Rhegmatogenous retinal detachment, one of the eye diseases, is a disease in which the retina detaches from the eyeball and requires emergency surgery. When rhegmatogenous retinal detachment occurs, scleral buckling is performed by fixing the retina by tying a fixative (e.g., sponge) near the retinal tear from the outside of the eyeball. Scleral buckling involves positioning the fixative near the retinal tear, inserting needles at regular intervals, and suturing the fixative to the eyeball.

Rhegmatogenous retinal detachment is a disease in which the retina, which is relatively located at the back of the eye, is detached. When performing scleral buckling, it is difficult for the surgeon to secure a sufficient surgical field of view for the back of the eye. In addition, when using existing surgical instruments such as calipers, it is difficult to access the back of the eye, making it difficult to insert the needle into the location where the fixture is to be sutured. This results in a longer surgical time, and if the needle is not inserted into the correct location, it can lead to the failure of the surgery.

The present invention aims to provide a corneal marker capable of performing efficient surgery and a marking device including the same.

In addition, the present invention aims to provide a corneal marker that can easily access the back of the eye and a marking device including the same.

In addition, the present invention aims to provide a marker capable of collectively marking a position where a needle is introduced, and a marking device including the marker.

Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as commonly understood by a person of ordinary skill in the art to which the present invention belongs. Terms defined in commonly used dictionaries, such as those defined in common dictionaries, should be interpreted in a meaning consistent with the meaning they have in the context of the relevant art, and shall not be interpreted in an idealized or overly formal sense unless explicitly defined below.

Fig. 1 is a cross-sectional side view schematically showing the appearance of an eye with a fixture sutured to an eye with rhegmatogenous retinal detachment. Figs. 2a and 2b are side views schematically showing the appearance of the eye according to the suture direction of the fixture. The relative sizes and positions of the tissues included in the eye of Fig. 1 may be somewhat different from the actual eye and may be somewhat exaggerated. In addition, the size and position of the fixture (20) shown in Figs. 2a and 2b may be different from the actual surgical location and may be somewhat exaggerated.

*Referring to FIG. 1, FIG. 2a and FIG. 2b, the eyeball (10) may be composed of the sclera (12) and the retina (14). The sclera (12) is positioned relatively outer among the structures forming the eyeball so as to completely surround the eyeball. The retina (14) is positioned behind the eyeball relative to the pupil compared to the sclera (12). In order to treat an eyeball (10) in which rhegmatogenous retinal detachment, which is one of the retinal diseases, has occurred, scleral buckling may be performed. The scleral buckling is performed by positioning a fixture (20) near the location of a retinal tear, inserting a needle near where the fixture (20) is located, and suturing and fixing the fixture (20) on the eyeball. By suturing the fixture (20) on the eyeball, the pressure and potential of the eyeball structure are increased, thereby restoring and adhering the detached retina (14) to its original position, thereby treating rhegmatogenous retinal detachment.

The fixture (20) according to one embodiment may be a medical sponge. The sponge may be a silicone sponge product of MIRA (USA) (e.g., Silicon Sponge-506) and/or FCI (France) used when performing corneal buckling. The sizes of silicone sponge products of MIRA (USA) and/or FCI (France) may be standardized.

For example, as illustrated in FIG. 2a, the fixture (20) may be positioned near a position corresponding to a retinal tear location (T) of the eyeball (10). At this time, the fixture (20) may be positioned and sutured on the eyeball (10) with its longitudinal direction facing horizontally. Here, the horizontal direction may be understood as a direction that is generally orthogonal to the direction toward the pupil when the eyeball (10) is viewed from the side. According to one embodiment, in the scleral buckle surgery in which the fixture (20) is positioned horizontally and sutured on the eyeball (10), the fixture (20) must be positioned to cover the retinal tear location (T) and then sutured on the eyeball at a certain vertical interval. More preferably, the fixture (20) is sutured onto the eyeball (10) by inserting the needle at a position spaced a first distance (D1) above the opening position (T) and a second distance (D2) below the opening position (T). In one embodiment, the first distance (D1) may be approximately 2.5 mm, and the second distance (D2) may be approximately 5 mm.

In addition, as an example, as illustrated in FIG. 2b, the fixture (20) may be sutured onto the eyeball (10) with its longitudinal direction oriented vertically at the retinal tear location (T) of the eyeball (10). Here, the longitudinal direction may be understood as a direction generally parallel to the direction toward the pupil when the eyeball (10) is viewed from the side. According to one embodiment, when the fixture (20) is sutured onto the eyeball (10) with its longitudinal direction oriented vertically, the fixture (20) must be sutured onto the eyeball (10) at a predetermined horizontal interval (e.g., the third interval (D3)) after the fixture (20) is positioned to cover the retinal tear location (T). For example, the third interval (D3) may be approximately 8 mm.

Depending on the patient's retinal detachment condition, the direction of the fixture (20) to be sutured on the eyeball (10) may vary. That is, depending on the patient's retinal detachment condition, the medical staff may suture the fixture (20) by positioning it in the vertical direction or by positioning it in the horizontal direction. Hereinafter, for the convenience of explanation, the case where the fixture (20) is sutured on the eyeball (10) with the longitudinal direction of the fixture (20) in the horizontal direction is defined as 'transverse surgery', and the case where the fixture (20) is sutured on the eyeball (10) with the longitudinal direction of the fixture (20) in the vertical direction is defined as 'vertical surgery'.

However, it is obvious that the examples of the first interval (D1), the second interval (D2), and the third interval (D3) described above may vary depending on the size specifications of the fixed body (20) (e.g., sponge).

FIG. 3 is a perspective view schematically showing a marking device according to one embodiment. FIG. 4 is a side view of the marking device of FIG. 3, FIG. 5 is a plan view of the marking device of FIG. 3, FIG. 6 is an enlarged view of part A of FIG. 3, and FIG. 7 is an enlarged view of part B of FIG. 3. Hereinafter, a marking device according to one embodiment of the present invention will be described in detail with reference to FIGS. 3 to 7, together with FIGS. 1, 2A, and 2B.

The marking device (30) according to one embodiment can be used for corneal buckling. More specifically, the marking device (30) can be used to mark on the cornea (12) the position where a needle is introduced to suture and adhere the fixture (20) on the eyeball (10). However, the present invention is not limited thereto, and the marking device (30) according to one embodiment can be used for various surgeries involving marking on the cornea (12) to treat various eye diseases. Hereinafter, for the convenience of understanding, a case in which the marking device (30) according to one embodiment is used for corneal buckling will be described as an example.

The marking device (30) may include a body (310), a connecting portion (330), and a marking portion (350). The body (310), the connecting portion (330), and the marking portion (350) may be formed integrally. However, the present invention is not limited thereto, and the body (310), the connecting portion (330), and the marking portion (350) may be formed separately and joined to each other by a method such as bonding. In addition, the body (310), the connecting portion (330), and the marking portion (350) may be made of a material including stainless steel. Without being limited to the above-described example, the body (310), the connecting portion (330), and the marking portion (350) may be manufactured by a combination of durable and relatively hard materials such as titanium, plastic, polycarbonate, or a combination of other appropriate materials.

The body (310) according to one embodiment may be a part that the operator grabs. The body (310) may generally have a rod shape. The cross-section of the body (310) may be circular. However, it is not limited thereto, and the body (310) may have various cross-sections such as a square or a hexagon. Although not shown, the body (310) may have a shape in which its diameter increases from the middle to the end to improve the operator's grabbing feeling. The operator may stably operate the marking device (30) by grasping the body (310) with his/her hand.

In one embodiment, a connecting portion (330) extends from a body (310) in the longitudinal direction of the body (310). More specifically, the connecting portion (330) may include a first connecting portion (331) and a second connecting portion (332). The first connecting portion (331) and the second connecting portion (332) may be formed symmetrically with respect to the body (310). The first connecting portion (331) extends from one end of the body (310), and the second connecting portion (332) extends from the other end of the body (310) opposite to one end of the body (310) in the longitudinal direction of the body (310). The first connecting portion (331) and the second connecting portion (332) may be formed in a generally conical shape. In addition, the first connecting portion (331) and the second connecting portion (332) may have a shape in which the diameter thereof decreases as they get farther away from the body (310). Due to the shapes of the first connecting portion (331) and the second connecting portion (332), the operator can easily secure a field of vision when performing corneal stenosis.

In one embodiment, the marking unit (350) can mark the position where the needle is introduced into the cornea (12) when performing corneal stenosis. The marking unit (350) can include a first marking unit (360) and a second marking unit (370). In one embodiment, the first marking unit (360) can mark the position where the needle is introduced into the cornea (12) when performing the 'horizontal surgery' described above, and the second marking unit (370) can mark the position where the needle is introduced into the cornea (12) when performing the 'vertical surgery' described above. A more detailed description thereof will be given later.

The marking portion (350) can be connected to the connecting portion (330). More specifically, the first marking portion (360) can be connected to the first connecting portion (331), and the second marking portion (370) can be connected to the second connecting portion (332).

A first marking portion (360) according to one embodiment may include a first marker body (361) and a first marker (362). The first marker body (361) according to one embodiment is connected to a first connecting portion (331). The first marker body (361) extends from the first connecting portion (331) in a direction away from the body (310) along a direction generally parallel to the longitudinal direction of the body (310). According to one embodiment, the first marker body (361) has a longitudinal direction parallel to the longitudinal direction of the body (310) when viewed from above.

In addition, the first marker body (361) may be formed to be curved when viewed from the side. That is, the first marker body (361) may be formed in a generally arc shape when viewed from the side. For example, when viewed from the side, the first marker body (361) may have its leading edge positioned higher than its distal edge. The first marker body (361) may be formed to have a curvature corresponding to the curvature of the eyeball (10). Here, the leading edge refers to the end of the first marker body (361) facing the distal edge, and the distal edge refers to the end of the first marker body (361) connected to the first connecting portion (331).

According to one embodiment, the first marker (362) is coupled to the first marker body (361). According to one embodiment, the first marker (362) may be coupled to the lower end of the first marker body (361). The first marker (362) may be provided in multiple numbers. For example, the number of first markers (362) may be three. According to one embodiment, the first marker (362) may include a first-first marker (364), a first-second marker (366), and a first-third marker (368).

According to one embodiment, the first-first marker (364), the first-second marker (366), and the first-third marker (368) may each have a truncated cone shape. That is, the first-first marker (364), the first-second marker (366), and the first-third marker (368) may each have a flat tip shape. The diameters of the tips of the first-first marker (364), the first-second marker (366), and the first-third marker (368) may be approximately 0.2 mm. Medical ink may be applied to the tip surfaces of each of the first-first marker (364), the first-second marker (366), and the first-third marker (368) to mark a position where a needle is introduced onto the cornea (12). More specifically, the first-first marker (364), the first-second marker (366), and the first-third marker (368) can mark the position where the needle is introduced on the cornea (12) during 'transverse surgery'. In addition, the lengths between the upper and lower ends of the first-first marker (364), the first-second marker (366), and the first-third marker (368) can all be the same.

The first-first marker (364), the first-second marker (366), and the first-third marker (368) may be spaced apart from each other at a predetermined interval and may be coupled to the lower end of the first marker body (361). Accordingly, the first-first marker (364), the first-second marker (366), and the first-third marker (368) may be spaced apart from each other in a direction that is generally parallel to the longitudinal direction of the body (310) when viewed from above.

The first-first marker (364) is formed at the tip of the first marker body (361). The first-third marker (368) is formed at the end of the first marker body (361). In addition, the first-second marker (366) is formed between the first-first marker (364) and the first-third marker (368). Due to the shape of the first marker body (361) described above, when the first-first marker (364), the first-second marker (366), and the first-third marker (368) are viewed from the side, the first-first marker (364) can be positioned higher than the first-second marker (366), and the first-second marker (366) can be positioned higher than the first-third marker (368). That is, the first markers (362, 364, 366) can be spaced apart from each other in an arc so as to have a curvature corresponding to the curvature of the eyeball.

In one embodiment, a straight-line distance between the tip of the first-first marker (364) and the tip of the first-second marker (366) may be a second interval (D2), and a straight-line distance between the tip of the first-second marker (366) and the tip of the first-third marker (368) may be a first interval (D1). The first interval (D1) may be approximately 5 mm, and the second interval (D2) may be approximately 2.5 mm. Accordingly, the first marking portion (360) may accurately mark a point at which a needle is to be introduced into the sclera (12) in a corneal buckle technique in which the fixture (20) is placed horizontally and sutured onto the eyeball (10).

The second marking portion (370) according to one embodiment may include a second marker body (371) and a second marker (372). The second marker body (371) according to one embodiment has a length direction that is perpendicular to the length direction of the body (310) when viewed from above. In addition, the second marker body (371) is connected to the second connecting portion (332). For example, the middle of the second marker body (371) is connected to an end of the second connecting portion (332). In addition, the second marker body (371) may be formed to be curved when viewed from the front. That is, the second marker body (371) may be formed to have a generally arc shape when viewed from the front. For example, the second marker body (371) may be formed to be curved so that the middle is positioned at a lower height than both ends when viewed from the front. The curvature of the second marker body (371) can correspond to the curvature of the eyeball (10).

In one embodiment, the second marker (372) is coupled to the second marker body (371). In one embodiment, the second marker (372) may be coupled to the upper end of the second marker body (371). The second marker (372) may be provided in multiples, and as an example, two markers may be provided. In one embodiment, the second marker (372) may include a second-first marker (374) and a second-second marker (376).

According to one embodiment, the 2-1 marker (374) and the 2-2 marker (376) may each have a truncated cone shape. The tips of the 2-1 marker (374) and the 2-2 marker (376) may have a flat shape. The diameters of the tips of the 2-1 marker (374) and the 2-2 marker (376) may each be approximately 0.2 mm. Medical ink may be applied to the tip surfaces of the 2-1 marker (374) and the 2-2 marker (376), respectively, to mark a position where a needle is introduced onto the sclera (12). More specifically, the 2-1 marker (374) and the 2-2 marker (376) may mark a position where a needle is introduced onto the sclera (12) during 'vertical surgery'. In addition, the lengths of the 2-1 marker (374) and the 2-2 marker (376) may both be the same.

The 2-1 marker (374) and the 2-2 marker (376) may be spaced apart from each other by a certain interval. In addition, the 2-1 marker (374) and the 2-2 marker (376) may be respectively coupled to the upper end of the 2nd marker body (371). Accordingly, the 2-1 marker (374) and the 2-2 marker (376) may be spaced apart from each other along a direction orthogonal to the longitudinal direction of the body (310) when viewed from above. In addition, the arrangement direction of the 2-1 marker (374) and the 2-2 marker (376) may be orthogonal to the arrangement direction of the 1-1 marker (364), the 1-2 marker (366), and the 1-3 marker (368) when viewed from above.

The second-first marker (374) and the second-second marker (376) may be formed at both ends of the second marker body (371), respectively. The second-first marker (374) and the second-second marker (376) may be arranged at substantially the same height when viewed from the front. The straight-line distance between the tip of the second-first marker (374) and the tip of the second-second marker (376) may be a third interval (D3). The third interval (D3) may be approximately 8 mm. Accordingly, when the second marking portion (370) is sutured onto the eyeball (10) while the fixture (20) is placed in a vertical direction, the point at which the needle is to be introduced into the cornea (12) may be accurately marked.

The first marking unit (360) can accurately and uniformly mark the position where the needle is to be introduced on the sclera (12) when performing corneal scleroptosis with the fixture (20) placed horizontally. In addition, the second marking unit (370) can accurately and uniformly mark the position where the needle is to be introduced on the sclera (12) when performing corneal scleroptosis with the fixture (20) placed vertically. That is, when corneal scleroptosis is performed using the marking device (30) according to one embodiment of the present invention, the fixture (20) can be placed horizontally or vertically and a retinal slit can be adhered using one device. That is, by changing the markers (362, 372) according to the fixing direction of the fixture (20) depending on the retinal detachment condition of the patient and using them, efficient corneal scleroptosis can be performed. In addition, since the intervals of the markers (362, 372) for marking the insertion positions of the needles are determined and designed to correspond to the size of the standardized fixture (20), marking can be performed at an exact position on the cornea (12) at once, thereby shortening the surgical time. In addition, since the first marker body (361) and the second marker body (371) are formed to have a curvature corresponding to the curvature of the eyeball, the marking device (30) can easily enter the retinal retinal hole position at the back of the eyeball (10) while minimizing secondary damage to the eyeball (10).

Below, a marking device according to another embodiment of the present invention will be described. Since the marking device described below has a structure that is mostly the same or similar to the marking device described with reference to FIGS. 3 to 7, a description of overlapping content will be omitted.

Figure 8 is a perspective view schematically showing a marking device according to another embodiment.

Referring to FIG. 8, protrusions may be formed on the outer surface of the body (310) according to one embodiment. The protrusions formed on the outer surface of the body (310) may be arranged in a grid shape. The shape of the protrusions may be variously modified within a range that can be modified by those skilled in the art. The grip of the operator for the marking device (30) is improved by the protrusions formed on the outer surface of the body (310), so that when performing corneal buckling surgery, the marking device (30) can be minimized from slipping out of the operator's hand, thereby further improving the efficiency of the surgery.

In addition, according to one embodiment, the marking device (30) may be provided as a kit. Here, the marking device (30) includes both the marking device described with reference to FIGS. 3 to 7 and the marking device described with reference to FIG. 8. More specifically, the marking device (30) may be packaged in a sterilized state in a packaging material and provided as a kit. The marking device (30) may be accommodated in a packaging material (e.g., a tray, etc.). In addition to the marking device (30), an instruction manual for the marking device (30) may be further accommodated inside the kit.

The above detailed description is illustrative of the present invention. In addition, the above contents are described by showing a preferred embodiment of the present invention, and the present invention can be used in various other combinations, changes, and environments. That is, changes or modifications are possible within the scope of the inventive concept disclosed in this specification, the scope equivalent to the written disclosure, and/or the scope of technology or knowledge in the art. The written embodiment describes the best state for implementing the technical idea of the present invention, and various changes required for specific application fields and uses of the present invention are also possible. Therefore, the above detailed description of the invention is not intended to limit the present invention to the disclosed embodiments. In addition, the appended claims should be interpreted to include other embodiments.

According to embodiments of the present disclosure, a corneal marker and a marking device including the same can efficiently suture a fixture to a retinal tear location.
