Description

{Sterile drapes applied to surgical instruments}

The present invention relates to a sterile drape applicable to a surgical instrument, and more particularly, to a sterile drape applicable to a manually operable surgical instrument.

In medicine, surgery refers to the treatment of diseases by cutting, cutting, or manipulating the skin, mucous membrane, or other tissues using medical devices. In particular, laparotomy, which involves cutting open the skin of the surgical site and treating, shaping, or removing the organs inside, can cause problems such as bleeding, side effects, patient pain, and scars. Therefore, recently, surgery that only inserts medical devices such as a laparoscope, surgical instruments, or microsurgical microscopes through a small hole in the skin or surgery using a robot is gaining attention as an alternative.

A surgical instrument is a tool for operating on a surgical site by operating an end tool equipped at one end of a shaft that passes through a hole made in the skin, by directly manipulating it with the doctor's hand or by using a robotic arm using a predetermined driving unit. The end tool equipped on the surgical instrument performs rotating motions, gripping motions, cutting motions, etc. through a predetermined structure.

Meanwhile, although the end tools and shafts of surgical instruments are sometimes treated as disposable, the control parts including the driving parts are reused, so reusable handheld instruments require sterilization. For this purpose, the control parts of handheld instruments are sometimes covered with disposable sterile drapes.

For existing reusable handheld instruments, a disposable sterilization drape is covered for sterilization and fixed using fasteners or Velcro, etc. Existing sterilization drapes are made of polymer materials, which are slippery and inconvenient to handle during surgery, and the visibility of the UI is significantly reduced, which may cause usability problems.

FIG. 1 is a perspective view showing an example of a surgical instrument to which an embodiment of the present invention is applied.

The surgical instrument illustrated in FIG. 1 is a manually operable surgical instrument for use in laparoscopic surgery or various other surgeries, and the device illustrated in the drawing represents a handheld instrument equipped with a surgical stapler.

When performing laparoscopic surgery, a suture device inserted into the body is used to suture the surgical site within the abdominal cavity. A surgical stapler that sutures the surgical site using medical staples is used as the suture device.

Surgical staplers have the advantage of not only shortening the operation time but also achieving precise suturing of the surgical site because they can perform the cutting of the surgical site and the anastomosis of the organ at the same time. In addition, surgical staplers are widely used in modern surgical operations because they have the advantage of faster recovery and less scarring than surgical sutures used for tissue cutting and suturing. In particular, surgical staplers are widely used in cancer surgery to cut cancer tissue and suture the cut site.

Referring to FIG. 1, a surgical instrument (10) has an end tool (100) that performs operations such as cutting and suturing tissue during surgery, and has a control unit (200) that controls the operation of the end tool (100). In addition, a connecting unit (400) that connects the control unit (200) and the end tool (100) may be included. Here, the end tool (100) is exemplified as being equipped with the above-described surgical stapler, but the spirit of the present invention is not limited thereto, and various tools that can perform operations such as gripping, cutting, and suturing may be used.

The control unit (200) is equipped with an interface that can be directly controlled by the doctor, such as a forceps shape, a stick shape, a lever shape, etc. When the doctor controls it, the end tool (100) connected to the interface and inserted into the body of the surgical patient performs a predetermined operation, thereby performing the surgery.

Here, the control unit (200) is illustrated as being formed in a shape having a handle (201) and an operating button (230), but the idea of the present invention is not limited thereto, and various forms of control units that are connected to the end tool (100) and can operate the end tool (100) are possible.

Meanwhile, the control unit (200) may be an electronic device including a drive unit including a battery and a drive motor. And, it may include a display unit (220) that displays information regarding the operation of the control unit (200).

In this way, the control unit (200) including various electronic devices is manufactured to be reused rather than being manufactured as a disposable device, unlike the end tool (100) and the connecting unit (400). Meanwhile, since sterilization and maintenance of a sterile state of surgical instruments are necessary to prevent infection of patients, the control unit (200) is also used by covering it with a disposable sterile drape.

However, the sterile drapes used in existing reusable handheld instruments wrap the instrument and secure it using fasteners or Velcro, but they are made of polymer materials, which makes it slippery when the user holds the handle or uses the operation buttons, causing inconvenience in operation during surgery, and the visibility of the UI, such as the display section, is significantly reduced, which may cause problems in usability.

The present invention was conceived to solve the above-mentioned problems, and the problem-solving means of the present invention will be explained through the following examples.

(Example 1)

FIG. 2 is a side view showing an example in which a sterilizing drape according to the first embodiment of the present invention is applied to a surgical instrument. FIG. 3 is a perspective view showing a fastening portion of the sterilizing drape of FIG. 2, FIG. 4 is a perspective view showing a button portion of the sterilizing drape of FIG. 2, and FIG. 5 is a perspective view showing a screen display portion of the sterilizing drape of FIG. 2. Here, FIGS. 3 to 5 are drawings in which the drape body (301) shown in FIG. 2 is omitted.

Referring to FIGS. 2 to 5, a sterilizing drape (300) according to the first embodiment of the present invention may include a drape body (301), a fastening portion (310), a screen display portion (320), and a button portion (330).

A sterile drape (300) according to an embodiment of the present invention is prepared before surgery to cover the manipulation unit (200), and the following procedures may be required. The sterile drape (300) according to an embodiment of the present invention is a disposable drape, and can be sterilized and individually packaged. Then, the packaged sterile drape (300) can be taken out by a sterile area user with the help of a non-sterile area user.

The sterile drape (300) includes a fastening portion (310), a screen display portion (320), a button portion (330), etc., formed of a different material from the drape body (301), and may additionally be equipped with various markers, fasteners, etc. That is, the sterile drape (300) may be folded with the above components equipped. The sterile drape (300) is folded so that it can be unfolded without being obstructed by the above components, and may be folded in layers in a pleated manner, for example, like an accordion. Alternatively, the remaining drape portion may be folded so that the fastening portion (310) described below is arranged on the outside of the sterile drape (300).

Here, the fastening portion (310) is a portion that is preferentially fastened to the joining portion (210) of the control portion (200), and after the fastening portion (310) is fastened to the control portion (200), the drape body (301) may be packaged in a state where it is turned over with respect to the fastening portion (310) so that the draping process of wrapping the drape body (301) around the control portion (200) is easy. In other words, the packaged sterile drape (300) may be in a state where the outer surface and inner surface are turned over so that the inner surface of the drape body (301), which is a portion that comes into contact with the outer surface of the control portion (200), is exposed to the outside. For example, the sterile drape (300) illustrated in FIG. 2 is a sterile drape (300) that covers the control unit (200), and the sterile drape (300) before wrapping the control unit (200) can be described as being in an inverted state.

The user can take out the packaged sterilized drape (300), attach the fastening part (310) to the control part (200), and drape the drape body (301) by turning it over so that it wraps around the control part (200). Then, after fixing the drape body (301) to each position of the control part (200), the open part of the end of the drape body (301) can be sealed using a device such as Velcro or a fastener to complete the draping. Thereafter, the connection part (400) of the instrument can be attached to the fastening part (310).

The drape body (301) is a portion that covers the control unit (200) of the surgical instrument (10) and may be formed of a flexible material. Additionally, at least one area may be formed of a rigid material. As shown in the drawing, the drape body (301) is formed to cover the front of the control unit (200) and may include a fastening unit (310), a screen display unit (320), a button unit (330), etc., which will be described later.

Meanwhile, at least one of the fastening portion (310), the screen display portion (320), and the button portion (330) to be described later may be formed of a material with lower flexibility or higher hardness than the drape body.

The fastening portion (310) may be formed at one end of the drape body (301). Specifically, the fastening portion (310) may be formed to be positioned on the coupling portion (210) side of the control portion (200) that is interposed between the control portion (200) and the end tool connection portion (400) and coupled with the connection portion (400). In addition, the fastening portion (310) formed at one end of the drape body (301) may be coupled with the control portion (200) and the connection portion (400). In other words, one side of the fastening portion (310) may be coupled with the end tool connection portion (400), and the other side of the fastening portion (310) may be coupled with the control portion (200).

Meanwhile, the fastening member (310) may be formed of a rigid material, unlike the drape body (301). Unlike the flexible drape body (301), the fastening member (310) is positioned between the connecting member (400) and the control member (200) and primarily serves to fasten the drape body (301) to the control member (200), but also serves as an intermediary for fastening the connecting member (400) to the control member (200), and therefore may be formed of a high-strength material.

In addition, the fastening member (310) may have a step (311) formed on the outer surface of one side facing the fastening member (210) so that it can be fixed to the fastening member (210) of the control member (200). Alternatively, the fastening member (210) may also have a step (211) formed on the outer surface of one side facing the fastening member (310). The step (311) of the fastening member (310) may be fastened by force-fitting to the step (211) of the fastening member (210) or another portion to be coupled with the fastening member (210).

Meanwhile, the fastening part (310) may have an ID chip (not shown) built in, and the control part (200) may include a recognition part (not shown) that comes into contact with the ID chip.

Here, when the fastening part (310) is fastened to the control part (200), the ID chip can come into contact with the recognition part of the control part (200) and at the same time, a pre-set system can be operated. For example, when the ID chip is recognized, the control part (200) can notify that the sterilization drape (300) has been fastened through the display part (220) of the control part (200) and provide information confirming that the sterilization drape (300) is a disposable product. For example, the product can be operated by the ID chip to provide various information such as genuine product authentication, LOT and serial number, and whether or not it can be reused.

In addition, after the sterilization drape (300) is fastened to the control unit (200) or the sterilization drape (300) is fastened to the control unit (200) and the instrument's connection unit (400) is fastened to the fastening unit (310), the power system of the control unit (200) can be operated. That is, the control unit (200) can automatically start power-on (System Power ON) and status check without a separate power button operation.

In addition, the fastening portion (310) may include a magnetic material on one surface facing the coupling portion (210), and the coupling portion (210) of the control portion (200) may also include a magnetic material on one surface facing the coupling portion (310). Specifically, as illustrated in FIG. 3, the coupling portion (210) of the control portion (200) may include an N-pole magnetic material (212a) and a S-pole magnetic material (212b) on one surface facing the coupling portion (310), and the fastening portion (310) may include an S-pole magnetic material (312b) and an N-pole magnetic material (212a) at positions corresponding to the N-pole magnetic material (212a) and the S-pole magnetic material (212b), respectively. However, the number of magnetic bodies included in the fastening portion (310) and the joining portion (210) and the arrangement of the magnetic bodies are not necessarily limited, and the number of magnetic bodies and the arrangement method may vary.

In addition, the control unit (200) may include a protrusion (213) that protrudes from the coupling unit (210) toward the connection unit (400). The connection unit (310) may form a penetration unit (313) so that the protrusion (213) may penetrate the coupling unit (310) and be connected to a receiving unit (not shown) formed in the coupling unit (403) of the connection unit (400), respectively. Here, the protrusion (213) may perform a role of transmitting power by the rotation of the motor of the control unit (200) to the connection unit (400). Here, the protrusion (213) is illustrated as a kind of pin shape, but the spirit of the present invention is not limited thereto, and may be formed in any shape as a means for transmitting power of the control unit (200).

Meanwhile, in order for the protrusion (213) transmitting the power of the control unit (200) to be connected one-to-one with the receiving portion formed in the coupling portion (403) of the connection unit (400), the coupling portion (403) of the connection unit (400) and the fastening portion (310) can be coaxially aligned. That is, the fastening portion (310) is coupled with the coupling portion (210) of the control unit (200) at a predetermined position, and the connection unit (400) is coupled while being aligned with a predetermined position of the fastening portion (310), so that the connection unit (400) can be coaxially aligned with the control unit (200).

Specifically, the joining portion (403) of the connecting portion (400) and the joining portion (314) of the fastening portion (310) may be formed as a male-female structure. For example, the joining portion (314) of the fastening portion (310) may form a slit-shaped position fixing portion (not shown), and the joining portion (403) of the connecting portion (400) may form a fixing pin (not shown) that protrudes toward the fastening portion (310) and has a shape corresponding to the slit shape.

Therefore, when connecting the connecting part (400) to the fastening part (310), it is necessary to adjust the position by rotating the connecting part (400) so that the fixing pin is fitted into the position fixing part of the fastening part (310). Then, when the fixing pin is fitted into the slit-shaped position fixing part, the connecting part (400) can be coaxially aligned with the fastening part (310) and the control part (200).

Or, conversely, a fixing pin protruding toward the connecting portion (400) may be formed in the fastening portion (310), and a slit-shaped position fixing portion corresponding to the fixing pin may be formed in the joining portion (403) of the connecting portion (400).

Alternatively, an elastic hook may be formed on one of the connecting portion (403) and the fastening portion (310), and a groove may be formed on the other at a position corresponding to the hook. Then, when the connecting portion (403) is fastened to the fastening portion (310), the hook may be elastically deformed and fitted into the groove.

Meanwhile, the screen display unit (320) is formed on the drape body (301) and can be formed at a position corresponding to the display unit (220) of the control unit (200).

In addition, the screen display unit (320) may be formed of a rigid material, unlike the drape body (301). In addition, the screen display unit may be formed of a light-transmitting material and may be formed in a shape corresponding to the display unit (220) of the control unit.

Specifically, as illustrated in FIG. 5, the body (202) of the control unit (200) may include a user interface (UI) that provides visual information to the user and can be used as a means of operating the device. Meanwhile, in order to easily check this UI, the drape body (301) needs to be in close contact with the display unit (220) of the control unit (200). Accordingly, the screen display unit (320) may be formed of a rigid material, unlike the flexible drape body (301), and may be formed to fit the shape of the display unit (220). In addition, in order to easily check the display unit (220), the screen display unit (320) may be formed of a material with high light transmittance.

In addition, the screen display unit (320) may include a magnet on one surface facing the display unit (220), and the display unit (220) may also include a magnet on one surface facing the screen display unit (320). Specifically, as illustrated in FIG. 5, the display unit (220) may include an N-pole magnet (221a) and a S-pole magnet (221b) on one surface facing the screen display unit (320), and the screen display unit (320) may include an S-pole magnet (321b) and an N-pole magnet (221a) at positions corresponding to the N-pole magnet (221a) and the S-pole magnet (221b), respectively. However, the number of magnets and the arrangement of the magnets included in the screen display unit (320) and the display unit (220) are not necessarily limited, and the number of magnets and the arrangement method may vary.

Meanwhile, the screen display unit (320) may be formed of a flexible material. For example, the drape body (301) corresponding to the display unit (220) may be formed of a material having good light transmittance and elasticity. Alternatively, the entire drape body (301) may be formed of an elastic material.

In this way, the screen display unit (320) may be a drape portion made of an elastic material, and when the drape body (301) wraps around the control unit (200), the drape body may be adhered to part or all of the control unit (200) by the elastic force. Or, the drape may be adhered to at least the display unit (220). Through this, the drape body (301) and the display unit (220) are adhered to each other to ensure visibility, so that a separate attachment element may not be required.

Meanwhile, the button portion (330) is formed on the drape body (301) and can be formed at a position corresponding to the operating button (230) of the control portion (200). In addition, unlike the drape body (301), the button portion (330) can be formed of a hard material.

The button portion (330) may be formed to fit the protruding shape of the attached operation button (230). For example, as illustrated in FIG. 4, the button portion (330) may include a base plate (331) and a button receiving portion (332). Here, the base plate (331) may include a magnetic material to be described later and may be a base surface on which the button receiving portion (332) may be formed.

The base plate (331) may include a button receiving portion (332) that protrudes in the opposite direction based on one surface that comes into contact with the portion of the handle (201) on which the operating button (230) is formed. To express this from another perspective, the button receiving portion (332) may be described as forming a concave portion that is concave in the same direction as the protrusion direction of the operating button (230) protruding from the handle (201). That is, when the base plate (331) is in close contact with the operating button (230) or the handle (201) adjacent to the operating button (230), the button receiving portion (332) may receive the operating button (230) in the concave portion therein.

Meanwhile, unlike the above, it can be assumed that the operation button (230) of the control unit (200) is not formed to protrude outward from the handle (201) but is formed flat, or rather, the operation button (230) is formed in a concave engraved shape. That is, if the operation button (230) formed on the handle (201) protrudes, the protruding portion may interfere when the drape is mounted, so the operation button (230) may be formed flat. In this case, the button portion (330) may be formed in a shape that protrudes from the base plate (331) toward the operation button (230). That is, the button portion (330) may be formed in a convex shape so as to protrude toward the inside of the drape body (301). Therefore, the user can press the operation button (230) of the control unit (200) by pressing the button portion (330).

Here, the base plate (331) may be formed of a material with higher hardness than the drape body (301), and the button receiving portion (332) may be formed of a material with lower flexibility than the drape body (301). That is, the button receiving portion (332) may be described as being more flexible than the base plate (331).

Accordingly, the base plate (331) can be firmly attached to the handle (201) of the control unit (200), and since the button receiving portion (332) can change shape by external pressure, it can be easy to press the operating button (230) received in the button receiving portion (332) by pressurizing the button receiving portion (332).

Therefore, the sterilization drape (300) according to the first embodiment of the present invention may not cause inconvenience to the user when pressing the operation button (230) even if it completely covers the control unit (200).

Meanwhile, the base plate (331) of the button portion (330) may include a magnet on one surface facing the operation button (230), and the operation button (230) may also include a magnet on one surface facing the base plate (331). Specifically, as illustrated in FIG. 4, the base plate (331) may include an N-pole magnet (333a) and a S-pole magnet (333b) on one surface facing the operation button (230), and the operation button (230) may include an S-pole magnet (233b) and an N-pole magnet (233a) at positions corresponding to the N-pole magnet (333a) and the S-pole magnet (333b), respectively. However, the number of magnets and the arrangement of the magnets included in the base plate (331) and the operation button (230) are not necessarily limited, and the number of magnets and the arrangement method may vary.

Meanwhile, the drape body (301) may include an identification mark (not shown) indicating a position corresponding to a position where it is fixed to the control unit (200). For example, a position where the sterile drape (300) is to be fixed may be indicated on a corner of the handle (201) and the body (202) of the control unit (200), and an identification mark (not shown) may be formed on the drape body (301) at a position corresponding to the indication. For example, letters or numbers may be indicated on the corresponding fixing portions of the control unit (200) and the drape body (301) to distinguish them, and the drape body (301) may be positioned on the control unit (200) according to the corresponding letters or numbers.

In addition, the drape body (301) includes a fixing means in an area adjacent to the identification mark, and the sterile drape (300) can be fixed to the control unit (200) through the fixing means. Here, the fixing means can include a fastener or Velcro, and the fixing means can be a magnetic body. Or, other than these, it can be various means that can attach the drape body (301) to the control unit (200).

In addition, the drape body (301) may include an area where a plurality of surface roughnesses are formed. And, the area where a plurality of surface roughnesses are formed may be formed at a position corresponding to the handle (201) of the control unit (200).

Here, the surface roughness may be formed on the outer surface of the drape body (301) or may be formed on the inner surface. Here, the surface roughness may provide friction when the user holds the handle (201) or may provide friction to the inner surface of the drape body (301) that comes into contact with the control unit (200).

Meanwhile, the screen display unit (320) may form an anti-glare layer through surface roughness. For example, an anti-glare layer including micro-sized beads may be formed on the inner or outer surface of the screen display unit (320) to scatter reflected light and implement a function of preventing glare from external lighting.

(Modification of the first embodiment)

Hereinafter, a sterilizing drape according to a modified example of the first embodiment of the present invention will be described. The sterilizing drape according to the modified example of the first embodiment of the present invention is characterized by a fastening portion (310) that is different from the drape according to the first embodiment of the present invention.

FIG. 6 is a perspective view showing an example of a sterilizing drape according to a modified example of the first embodiment of the present invention being applied to a surgical instrument, and FIG. 7 is a side view showing a state in which the sterilizing drape of FIG. 6 is applied to a surgical instrument.

Referring to FIGS. 6 and 7, a sterilizing drape (300) according to a modified example of the first embodiment of the present invention can be formed by integrally connecting a drape body (301) and a fastening portion (310) with an end tool connecting portion (400) of a surgical instrument.

That is, the sterilizing drape (300) according to the first embodiment of the present invention includes a fastening portion (310) at one end of the drape body (301), and the fastening portion (310) is interposed between the coupling portion (210) of the control portion (200) and the coupling portion (400), so that the fastening portion (310) is coupled with the control portion (200) and also coupled with the coupling portion (400), but the sterilizing drape (300) according to the modified example of the first embodiment of the present invention can be described as having the drape body (301) integrally coupled with the coupling portion (400). Specifically, the coupling portion (400) may include an adapter (404). The adapter (404) may be formed at an end of the connection portion (400) in a form in which the coupling portion (403) of the connection portion (400) and the coupling portion (310) are integrated into one. That is, an end tool (100) may be coupled to one end of the connecting portion (400) and an adapter (404) may be coupled to the other end. Here, the adapter (404) may be coupled to a sterile drape (300) including a drape body (301).

Meanwhile, the sterile drape (300) coupled to the adapter (404) is provided to drape the control unit (200) by unfolding the drape body (301) in the direction in which the end tool connection part (400) is connected to the control unit (200), and the drape body (301) may be folded to a predetermined volume on the end tool connection part (400) side before unfolding toward the control unit (200). Here, the predetermined volume means a volume smaller than the volume after the drape body is unfolded, and preferably means the minimum volume possible when the drape body is folded. That is, the drape body may be folded so that the sterile drape can be packaged with a minimum volume when the end tool and connection part, which are integrally formed with the sterile drape, are packaged.

Specifically, as illustrated in FIG. 6, a portion of the drape body (301) is formed attached along the periphery of the adapter (404), and the remaining drape body (301) may be folded in layers. In addition, as illustrated in FIG. 7, when the end tool connecting portion (400) is mounted on the control unit (200), the folded portion of the drape body (301) formed attached to the adapter (404) may be unfolded and expanded to cover the control unit (200).

In this way, a dedicated sterilization drape (300) used for the surgical instrument (10) is provided so that there is no inconvenience in use, and since the sterilization drape (300) is attached to the disposable end tool connection part (400), there is no need to separately provide a sterilization drape, and the sterilization drape (300) can be used by covering the control part (200) at the same time as attaching the surgical instrument, which is very convenient and can shorten the surgical time.

Meanwhile, a sterilizing drape (300) according to a modified example of the first embodiment of the present invention may also include a screen display portion and a button portion. Although not shown in the drawing, the screen display portion and button portion formed in one area of the drape body (301) are substantially the same as the screen display portion (320) and button portion (330) of the sterilizing drape (300) according to the first embodiment of the present invention.

The screen display unit (320) and the button unit (330) may be formed of a material having lower flexibility or higher hardness than the drape body (301). In addition, the control unit (200) includes a first magnetic body arranged in at least one area, and the sterile drape (300) has a second magnetic body arranged in a position corresponding to the magnetic body of the control unit (200), and the first magnetic body and the second magnetic body may contact each other to fix the sterile drape (300) to the control unit (200). Specifically, the screen display unit and the button unit may include magnetic bodies, and the drape body (301) may be attached and fixed to the control unit (200) by contacting each of the magnetic bodies formed in the corresponding positions of the control unit (200).

Meanwhile, the drape body (301) may be formed in a shape corresponding to the shape of the control unit (200). That is, when covering the control unit (200) with the drape body (301), the space between the control unit (200) and the drape body (301) can be minimized, thereby reducing the sense of incongruity when the user holds the control unit (200) and operates the operation button (230).

In addition, the drape body (301) may include an area where a plurality of surface roughnesses are formed. And, the area where a plurality of surface roughnesses are formed may be formed at a position corresponding to the handle (201) of the control unit (200).

Here, the surface roughness may be formed on the outer surface of the drape body (301) or may be formed on the inner surface. Here, the surface roughness may provide friction when the user holds the handle (201) or may provide friction to the inner surface of the drape body (301) that comes into contact with the control unit (200).

Meanwhile, the screen display unit (320) can form an anti-glare layer through surface roughness. For example, an anti-glare layer including micro-sized beads can be formed on the inner or outer surface of the screen display unit (320) to scatter reflected light and implement a function of preventing glare from external lighting.

(Example 2)

Hereinafter, a sterilizing drape according to a second embodiment of the present invention will be described. The sterilizing drape according to the second embodiment of the present invention is characterized by a drape body (501) that is different from the drape according to the first embodiment of the present invention.

FIG. 8 is an enlarged perspective view showing a state in which a sterilizing drape according to the second embodiment of the present invention is applied to a surgical instrument.

Referring to FIG. 8, a sterile drape (500) according to a second embodiment of the present invention is formed by laminating a plurality of sterile drape layers in a drape body (501), and the plurality of sterile drape layers can be removed one by one from the outermost layer to the innermost layer and used. Here, the innermost layer means the sterile drape layer closest to the control unit (200), and the outermost layer means the sterile drape layer laminated outermost from the innermost layer.

In other words, it can be said that the drape body (501) covering the entire control unit (200) is formed of multiple sterile drapes rather than one sterile drape.

Here, the drape body (501) is formed by stacking multiple disposable drapes, so even if the sterile drapes are removed one by one after using the surgical instrument, another sterile drape is draped inside. Accordingly, the sterile state can be maintained during multiple surgeries, and since there is no separate procedure for attaching the drape each time it is used, simplification of the surgical procedure can be expected.

Meanwhile, the drape body (501) may include a mark (not shown) indicating the number of uses for each sterile drape layer. For example, a number indicating the number of sheets may be marked on each sterile drape layer.

Meanwhile, although not shown in the drawing, the sterilizing drape (500) according to the second embodiment of the present invention may also include one or more components of the fastening portion (310), the screen display portion (320), and the button portion (330) of the sterilizing drape (300) according to the first embodiment of the present invention.

Here, the plurality of sterile drape layers may each be connected to one of a fastening portion (not shown), a button portion (not shown), and a screen display portion (not shown).

For example, a plurality of sterile drape layers may be connected to the fastening portions, respectively, and an innermost layer among the plurality of sterile drape layers may be connected to the fastening portions, the button portion, and the screen display portion. In addition, a plurality of sterile drape layers excluding the innermost layer may be laminated on the button portion and the screen display portion.

Alternatively, each of the multiple sterile drape layers may be connected to the fasteners, button portions and display portions.

In addition, the drape body (501) may be formed with a cutting line that facilitates the removal of each sterile drape layer while being draped on the control unit (200). For example, as shown in FIG. 8, a cutting line may be formed on the upper side of the body (202) of the control unit (200). That is, a cutting line may be formed that extends from the distal part (500a) of the control unit (200) through the display part (220) of the control unit (200) to the proximal part (500b) of the control unit.

Additionally, a cutting line may be formed at the connection portion where the multiple sterile drape layers and the fastening portion, button portion and screen display portion are connected to facilitate the removal of each sterile drape layer.

On the other hand, the innermost layer of the plurality of sterile drape layers can be connected to the fastening portion, button portion, and screen display portion without a cut line. Therefore, the innermost layer can be stably draped on the control portion without being cut or separated.

The user can remove the drape layers one by one, starting from the outermost layers, by spreading the portion adjacent to the cut line to either side or by using a separate tool to cut the drape layers along the cut line.

Meanwhile, the drape body (501) may be formed of a light-transmitting material. As described above, in order to easily check the display unit (220) of the control unit (200), the drape body (501) corresponding to the corresponding portion may be formed of a highly light-transmitting material, or the front may be formed of a highly light-transmitting material.

In addition, the drape body (501) may include an area where a plurality of surface roughnesses are formed. And, the area where a plurality of surface roughnesses are formed may be formed at a position corresponding to the handle (201) of the control unit (200).

Here, the surface roughness may be formed on the outer surface of the drape body (501) or may be formed on the inner surface. Here, the surface roughness may provide friction when the user holds the handle (201) or may provide friction to the inner surface of the drape body (501) that comes into contact with the control unit (200).

Meanwhile, the drape body (501) can form an anti-glare layer through surface roughness. For example, an anti-glare layer including micro-sized beads can be formed on the inner or outer surface of the drape portion corresponding to the display portion (220) to scatter reflected light and implement a function of preventing glare from external lighting.

And, a friction function or an anti-glare function can be implemented through the drape layer of the outermost layer of the sterile drape (500), and since surface roughness is formed on each of a plurality of drape layers, even if the outermost layer is removed, the same function can be implemented by the surface roughness of the inner drape layer.

(Example 3)

Hereinafter, a sterilizing drape according to a third embodiment of the present invention will be described. The sterilizing drape according to the third embodiment of the present invention is characterized by a fastening portion (610) that is different from the drape according to the first embodiment of the present invention.

FIG. 9 is a perspective view showing a state in which a sterilizing drape according to a third embodiment of the present invention is applied to a surgical instrument, and FIG. 10 is a perspective view showing a fastening portion of the sterilizing drape and a vacuum pump tool of FIG. 9.

Referring to FIGS. 9 and 10, a sterilizing drape according to a third embodiment of the present invention may include a drape body (601) that wraps around a control unit of a surgical instrument and a fastening unit (610) formed at one end of the drape body (601) and coupled with the control unit (200).

One side of the fastening portion (610) may form a first fastening means (611) that is coupled with the control portion (200), and the other side of the fastening portion (610) may form an opening (612).

The first coupling means (611) of the fastening portion (610) may form a step on the outer surface of one side facing the fastening portion (210) so that it can be fixed to the fastening portion (210) of the control portion (200). Alternatively, the fastening portion (210) may also form a step (211) on the outer surface of one side facing the fastening portion (610). The first coupling means (611) of the fastening portion (610) may be fastened by force-fitting to the step (211) of the fastening portion (210) or other portions to be coupled with the fastening portion (210).

The opening (612) is coupled with a vacuum pump tool (v12), and air filled between the drape body (601) and the control unit (200) can be removed through the vacuum pump tool (v12) to drape the drape body (601) so that it is in close contact with the control unit (200).

Specifically, the opening (612) may include a second coupling means (614) that can be coupled with the connecting portion (400), and may include a through hole (613) that acts as a passage for sucking internal air of the drape body (601) by being coupled with a vacuum pump tool (v12).

Meanwhile, the fastening member (610) may also function as a coupler that mediates the connection of the end tool connection member (400) and the control member (200), like the fastening member (310) of the sterilizing drape (300) according to the first embodiment of the present invention. That is, the fastening member (610) may be interposed between the end tool connection member (400) and the control member (200) of the surgical instrument, and the first coupling means (611) of the fastening member (610) may be coupled with the control member (200), and the second coupling means (614) of the opening (612) may be coupled with the end tool connection member (400).

As shown in Fig. 9, after draping the sterile drape (600) on the control unit (200), the fastening member (610) can be mounted on the control unit (200) and the vacuum pump tool (v12) can be operated through the opening (612) to ensure that the drape body (601) is in close contact with the control unit (200). Thereafter, by connecting the end tool connecting member (400) to the opening (612), the drape body (601) can be maintained in a state of being vacuum-absorbed to the control unit (200).

Through this, the sterilization drape (600) according to the third embodiment of the present invention can improve the operability of the operation button (230) and the visibility of the display unit (220).

As described above, the sterilizing drape according to an embodiment of the present invention is applicable to surgical instruments, and a surgical instrument to which the sterilizing drape according to an embodiment of the present invention is applied will be described.

The surgical instrument may include an end tool (100), a manipulator (200), and a connecting portion (400).

Here, the end tool (100) is inserted into the surgical site and performs a motion required for the surgery. As an example of such an end tool (100), a pair of jaws for performing a grip motion as illustrated in FIG. 1 may be used. However, the idea of the present invention is not limited thereto, and various devices for surgery may be used as the end tool (100). For example, a configuration such as a one-armed cauterizer may also be used as the end tool. Such an end tool (100) is connected to a control unit (200), and receives the driving force of the control unit (200) through a connection unit (400), thereby performing motions required for the surgery, such as a grip, cutting, and suturing motion.

Here, the end tool (100) may be provided with a pair of jaws, that is, a first jaw (101) and a second jaw (102), and the end tool (100) may be formed to be rotatable in one or more directions. In addition, the end tool (100) may include a staple and a blade. Specifically, one of the jaws may be provided with a staple and a blade. In addition, the control unit (200) may control the stapling operation and the cutting operation of the end tool (100).

Here, the end tool (100) can perform stapling and cutting operations simultaneously. That is, it can be explained that when body tissue is resumed between the first section (101) and the second section (102), suturing and cutting of the body tissue are performed simultaneously.

Here, the end tool (100) is shown as having a pair of jaws, i.e., the first jaw (101) and the second jaw (102), for performing a grip operation, but the idea of the present invention is not limited thereto, and it goes without saying that an end tool capable of performing various operations can be applied.

The connecting portion (400) can play a role of connecting the control portion (200) and the end tool (100). That is, one end of the connecting portion (400) can be connected to the end tool (100), and the other end can be connected to the control portion (200).

The control unit (200) is connected to the other end of the connecting unit (400) and is provided with an interface that can be directly controlled by a doctor, such as a handle, forceps shape, stick shape, lever shape, etc. When the doctor controls it, the end tool connected to the corresponding interface and inserted into the body of the surgical patient performs a predetermined operation, thereby performing the surgery. Here, the control unit (200) is illustrated as being formed of a handle that can be held with one hand and a main body, but the spirit of the present invention is not limited thereto, and various forms of control units that are connected to the end tool (100) and can operate the end tool (100) are possible.
