Abstract

Surgical suture tool according to the present invention and its application method is implemented with a variety of suture needles and sutures. According to the main embodiment of the present invention, the suture tool is composed of two needles (7) (8) which are temporarily joined to form a single point (9) having a quadrilateral, diamond or other shape in cross section. And a suture 10 having projections formed in the shape of a sawtooth on its surface. The jagged shape here is a very important factor because it can firmly connect the soft tissues and forcibly hold and hold the soft tissues even when a force is applied. The method of applying the suture tool according to the present invention includes inserting the two needles shallowly into one hole during parallel operation, wherein the needles are separated in two, and each needle moves along its contour. Such surgical suture tools are widely used for surgery and plastic surgery.

Description

SURGICAL SUTURE MATERIAL AND A METHOD TO THE USE THEREOF

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to instruments and methods for performing surgical operations and handwriting in the medical field, and more particularly to tools used in cosmetic surgery.

Sutures and needles are used as surgical suture tools, ie tools for suturing wound edges in surgical operations. The suture sutures the soft skin tissue of the outer surface using various types of needles or using a special tool instead of the needle to insert the needle into the tissue. These special tools are already disclosed and known in the following guns.

PCT Application PCT / RU2004 / 000252 (June 30, 2004)

European Patent EP 0205811A1 (December 30, 1986)

-Russian Patent RU 2186536 C2

-US Patent US 5342376 (August 30, 1994)

The needle is made of metal and steel is the most used. The needle may be straight or bent along its periphery, or else. One end of the needle is pointed and the other end has needle ears for the insertion of a surgical suture. Non-traumatic needles without needle ears have been used in recent decades to suture the edges of wounds, and sutures have been used to secure the needle in an industrial manner. Accordingly, the surgeon used disposable sterile sutures and suture needles, where an important point is that the suture needles do not have large needle ears and double sutures. This type of suture needle can cause trauma to the edge of the tissue during passage through the soft tissue with the suture.

The suture needle may be in the form of a double point pointed at both ends, in which case the suture may be coupled to the middle or extension of the needle. The shape of the needle depends on how it is applied during surgery.

The suture is non-traumatically connected to the needle and can be made of a nonabsorbent or absorbent material. In addition, the suture may be manufactured in the form of a unitary (one strand of fiber), woven, spun, or other material coated to have different thicknesses and strengths.

General characteristics of surgical suture needles include strength, smooth surface, and inertness that does not cause biological reactions. Surgical suture needles must penetrate the skin and easily pass through the subcutaneous tissue. Bending stitches are used to close open wounds with continuous sutures, and straight needles are not suitable in this case.

Surgical suture needles can be smooth or rough, and can also be shaped with protrusions arranged at angled portions of the surface.

Surgical closure methods for suturing wounds or subcutaneous tissues include intermittent closure, mattress closure, and continuous closure. Subcutaneous sutures are made in open wounds that must close the edges, which may be punctured without cutting the skin to tightly connect the soft tissues, or may be closed by suturing the skin briefly during endoscopic surgery. These two methods are applied to cosmetic surgery, which mainly sutures and tightens the subcutaneous tissue related to sewage and newly fixes the tissue to a higher position, which is cosmetically effective. Such surgery and manipulation can be done simply with a suture and a double point needle.

The protruding sutures, disclosed in US Pat. No. 5,053,047 dated Oct. 1, 1991, are used to suture the wound edge in a vertical single stitch fashion and are also used for continuous subcutaneous or intradermal sutures. However, the disclosed suture tools have some defect characteristics and are not suitable for advanced surgery.

When suturing open wounds according to the method disclosed in US WO-A-98 / 52473 dated May 21, 1997, the application of subcutaneous sutures alone results in misalignment of the skin edges of the wounds. However, when the suture method is applied to suture of the intradermal tissue, the appearance becomes noticeable. In addition, the suture method lacks a description of removing the suture after the wound has healed and will leave cosmetically inappropriate marks after surgery. Another drawback of the disclosed suture method is that it takes several times the suture to wounds of the same length compared to the continuous suture method, resulting in expensive surgical costs.

The suture tool disclosed in the U.S. Patent Case is unable to apply continuous sutures due to its excessive size and also leaves large surgical marks.

Sewing tools according to EP 1 075 843 are also very expensive. When sutures are wound with conventional non-traumatic sutures, the disclosed sutures can seal a wound of only 10 cm in one unit, whereas the suture of 7-10 cm can be sutured with a total of approximately 45 cm of sutures. It is also difficult to remove the suture after healing.

According to EP 1 075 843, the degree of engagement, strength and endurance of the suture joint in the second set is insufficient to prevent the free end of the suture from slipping in the depth direction of the wound. At the same time, the engagement degree, strength and durability of the first set of joints are sufficiently high. According to the invention, in fact the strength of the right and left sides of each joint is the same and the distance between the right and left sides of the joint is also equal. Each applied In a stitch, when the suture is stretched to some extent wrinkled at the edge of the wound, the tensile force of the first set of the second set gradually increases, and at some point it fails to overcome the tensile force and bends or ruptures, causing the suture to slide one turn into the depth of the wound. It will be lost. If the tensile force continues to increase, the same phenomenon occurs on the second and subsequent joints, eventually leading to the end of the suture into the skin. Even if this does not occur, there is a risk that the entire suture structure is loosened and the suture becomes unstable when the surgery is completed.

According to EP 1075 843, conical protrusions do not hold the skin tissue tight. In fact, tightening the sutures at both ends will gradually increase the pressure acting on the protrusions, causing the protrusions to unfold and bend vertically to the suture. The suture slides into the skin tissue one more time. That is, as confirmed above, when the sutures are tightened, the protrusions formed in the sutures do not change into a ring shape that couples the skin tissue, but are just bent. Therefore, sutures with protrusions are insufficient to be firmly fixed in the skin tissue. This is particularly important for the second group of joints.

Surgical practice often requires significant force to shrink the wound edge in the process of suturing the wound. At this point, the surgeon must mobilize a wide patch of skin thickness from both ends of the wound, which is not always possible. In addition, several layers of tight single stitch sutures must be applied to the skin as well as to the subcutaneous layer. In the case of a wide open wound, single stitches made at the edges of the wound, especially in the adipose tissue of the subcutaneous layer, leave a lot of holes, since the prior art suture needles cannot fix a large amount of skin tissue in the loop.

As the skin tissue is widely mobilized as described above, the wound edge is sutured several times, and the skin around the wound edge is pulled strongly, and further trauma occurs on the wound edge as well as the area adjacent to the wound, and the wound healing process is lengthened. The risk of opening the wound edge also increases, leaving rough, broad marks.

The use of double point surgical needles for tightening soft tissue, disclosed in PCT / RU2004 / 000252 (December 30, 2004), exhibits some of the defect characteristics of this suture tool.

Even if loose soft tissue is evenly and smoothly sutured and tightened without noticeable cuts and excessive pulling of the skin, the deformity of the sutures recurs very quickly, i. You are dissatisfied. The reason for the relapse is that the suture surface used for sutures is smooth and the skin tissue secured by the suture slips down easily.

"APTOS" sutures by RU 2268752 (PCT / RU 02/00285) also have defects.

Surgical results do not last long when loose soft tissues are tightened with APTOS suture according to the method disclosed in the patent case. Half of the protrusions formed on the APTOS suture according to the patent case act in the opposite direction to the other half in the skin tissue. Whether the protrusions are arranged opposite each other (left and right relative to the middle of the length direction) or staggered on each half of the suture, the amount of protrusions and their respective strength are sometimes insufficient to support the entire soft tissue mass. can do.

In addition, if the suture is not carefully inserted into the hole of the needle, the protrusions, particularly towards the sides of the suture movement, will bend and not spread in the tissue. This weakens one side of the suture engagement structure.

The weaknesses of these projections are explained by their structural defects. The lack of the number of protrusions is because only the protrusions formed on one side of the suture longitudinal direction serve to tighten the stretched tissues, while the protrusions on the other half hold and support the protrusions of the one side.

In view of these shortcomings of existing suture tools and methods of use, there is a need to apply a new, more effective surgical tool with protrusions to sutures so that the surgical wound can be more firmly sealed by a continuous molding suture method. There is a need for a new and effective method for contraction of surgical wound edges that requires considerable force. In addition, by applying a new surgical suture tool that combines the use of double point needles to suture the soft tissue internally and the APTOS suture clamping method, the surgery to clamp the tissues of the face, body and limbs effectively There is a need for action.

The present invention proposes a series of new forms of suture tools for use in surgical and plastic surgery and methods of use thereof, in order to solve the drawbacks of the suture tools and methods of use mentioned above.

In the suture tool according to the embodiment of the present invention including a suture needle made of metal, a polymer material or an organic material, and a suture having protrusions of the same material on the surface, the suture needle is temporarily attached to each other, It is characterized by consisting of two needles having four sides and forming one needle having a cross-section or other shape, and both ends of the suture are attached to the pointed ends of the needles, that is, different needles facing opposite points. The protrusions of any type are characterized in that their ends are arranged from both ends relative to the center of the suture such that the ends face away from the direction in which the suture is attached to the needles.

According to another aspect of the suture tool, the needle is in the form of a double point and the suture is fixed to a central part spaced apart from the points of the needles, and certain types of protrusions have their ends opposite to the direction in which the suture is attached to the needles. Characterized by facing.

The suture tool according to another aspect is characterized in that the needle is in the form of a double point with a suture and its ends are attached directly to either pointed end of the needle.

The suture tool according to another aspect is characterized in that it consists of a needle of the double point form with a suture having a protrusion shaped into a predetermined shape.

As another type of suture tool, the suture has serrated protrusions having various shapes of cross-sections of about 1.5 to 5 times its outer diameter, the protrusions having a quarter of the suture outer diameter from the surface at the base. The center portion is gradually deformed from the surface to the pointed end with about one third of the outer diameter of the suture, and when the suture is pulled again while suturing the soft tissue, it is formed to be bent into a fishing hook shape.

The surgery is performed in the following way. A method of applying a suture for closing a wound that requires force to retract an edge, wherein one point of the double point needle having a suture with some form of inclined protrusions has a predetermined depth on one side of the wound edges. And then the double point needle is moved parallel to the skin surface in a direction perpendicular to the wound edge from the desired distance from the wound edge, and then the inserted point is moved toward the skin surface but not pulled out completely, Leave the point at about the depth that the suture passed through and rotate the needle 90 degrees to continue the square stitch, joining both ends of the suture together.

The amount of stitches applied is determined as needed to secure and sufficiently secure the wound edges.

The method of suturing the wound edge through the continuous molding closure method is carried out as follows. The needle is inserted approximately 1 cm away from one end of the wound so that the point of the needle is inserted into the subcutaneous cell tissue of the wound, and successive stitches are applied to the edges of the wound in order to provide a Tighten the suture of each stitch with a predetermined force to puncture the wound and shrink the edge of the wound, and when necessary to complete the closure of the wound, puncture the other end of the skin surface with the needle to further tighten the suture, leaving the suture at least 3 cm above the skin. Clean up.

The method of applying a face lift plastic surgery surgical tool that lifts the soft tissues of the cheeks and cheekbones of the face comprises the steps of: puncturing the local area, inserting the suture needle into the subcutaneous tissue to a desired depth, and inserting the needle. Separating the two and moving each needle along the corresponding contour, and when rotating the needles, the next motion is continued along the remaining contours using the other point without pulling the needle completely out of the skin surface; Fastening the skin tissue, the needle is pulled from the first punctured position and the suture tool application method characterized in that to fix the suture in the same position, through which the quality of the surgical operation can be improved. The skin is not pulled in the locations where the sutures are bent, and this bend of the suture is located at the depth where the needle of the subcutaneous layer is separated.

The present invention presented can be illustrated by the following figures.

The surgical suture tool of the present invention and its method of use will be described through various types of needles and threads for performing surgical and plastic surgery.

1-4 show the components of the surgical suture. The suture 1 is made of metal, high molecular material or organic material and has a complex protrusion consisting of two sets on the surface. The ends of the protrusions of the first set 2 are positioned facing the direction of tightening the suture. The protrusions of the first set 2 are placed in the skin tissue and serve to effectively contract the edges of the wound, and the protrusions of the second set 3 face the suture clamping direction. The protrusions of the second set 3 lie on the skin surface to prevent slippage of the suture.

Figure 4 briefly shows the effect of the force of the skin tissue on the protrusions formed as described above. A series of types of surgical suture needles and sutures for performing this function and the manufacture of the suture tools are described.

In Fig. 5, the suture 1 is shown similarly to Figs. 1 and 2 with a suture needle 4 for closing the wound by a continuous suture method. The suture is provided with protrusions 2 and 3 of a predetermined type.

FIG. 6 shows a suture with two suture needles 5 and the protrusions 2 and 3 of the predetermined type in a similar fashion to the suture 1. The suture consists of a double suture that can be separated into two separate sutures during surgery.

The most characteristic of the various forms disclosed is shown in FIG. 10. The suture tool of FIG. 10 has two suture needles 7 and 8 temporarily joined together to form one suture needle 6 having a pointed end, ie a single point. The coupled needle has four sides and may have a rectangular or other shape in cross section. The suture 10 is attached to the ends 11 and 12 of each of the suture needles 7 and 8, and the protrusions 13 and 14 of the predetermined shape are formed from opposite ends relative to the center of the suture. The ends are positioned so as to face opposite sides attached to the suture needle.

The use of double-sided needles improves the quality of surgical and plastic surgery. The suture needle 6 is drilled into the subcutaneous layer in the desired depth, and then the suture needles 7 and 8 are separated so that each faces a different contour. After the needles are drilled through the marked points, i.e., where the needles are introduced, the bend of the suture enters the depth below the epidermal layer where the needles were separated.

Another application of the suture is shown in FIG. 11. A double point needle (15) consisting of needles (16) and (17) drills a hole in point A (see Fig. 17) above the cheekbone area and is suture 18 attached to the needle 16 and provided with protrusions of a predetermined shape. ) Along the triangular outlines A, B, and C. On the other hand, the double point needle 15 having the other half of the suture 18 causes the holes and the bends to follow the contours A ₁ , B ₁ , C ₁ , respectively. The protrusions of some type are bent and buried below the source of suture from where the protrusions are cut. When the needles return to the point A again and a knot is made, the skin tissue is firmly fixed in the newly elevated position.

As described above, when suturing soft tissues with a double point needle having a suture having protrusions, the soft tissues are evenly distributed and can be fixed along the longitudinal direction of the suture, so that it is more reliable than clamping with a smooth suture without protrusions, The tissues do not fall or slip over time.

As a type of suture tool corresponding to this method, there is a suture in which predetermined protrusions are arranged in opposite directions along the entire length. The sutures are arranged in the form of flexible tubes, such as cellophane, to escape from the suture's path after surgery. The suture may be coated with an absorbent material.

7 and 8 show the types of stitching the wound in two layers using a suture. The form shown in FIG. 7 has two sutures and the other form according to FIG. 8 has one suture with protrusions formed in different directions.

According to another manner of applying the suture tool shown in FIGS. 12 and 13, the surgery is performed as follows. This method is a suture method in which a force is required to retract the edges of the wounds 19 and 20, which is a point of the double point needle 21 having a suture having bent protrusions in a predetermined shape, i.e. One end is inserted to one side of the edges of the wound to a predetermined depth, and then the double point needle 21 is moved parallel to the skin surface in a direction perpendicular to the wound edge from an unspecified distance from the wound edge. The inserted point is moved toward the skin surface but is not completely pulled out, leaving the other end at approximately the depth through which the suture passes. The needle is rotated 90 degrees to continue the square stitch, and the above method is performed on the remaining sides of the wound edge, and then the ends of the suture are joined to each other.

As described above, the present invention presented can be widely applied to various plastic surgery and surgery, and can also be applied in parallel with other surgery.

Surgical sutures presented in the present invention are feasible and widely applicable.
