Abstract
Description
Conjunctival marker and marking device including same
[0001] The present invention relates to a conjunctival marker and a marking device including the same, and more particularly, to a conjunctival marker and a marking device including the same for indicating a point at which an injection needle is inserted or withdrawn in a fixation technique for fixing a portion of an artificial lens within the cornea.
[0002] [Cross-reference to related applications]
[0003] This application claims priority from Korean Patent Application No. 10-2023-0085643, filed July 3, 2023, the entire contents of which are incorporated herein by reference.
[0004] When a patient develops an eye disease such as a cataract, a surgery is performed to implant an artificial lens into the eye. If the artificial lens is dislocated in the eye of a patient with an implanted artificial lens, a flanged intrascleral intraocular lens fixation (IOL fixation with double-needle technique) is required, which fixes a part of the IOL (e.g., the haptic) into the sclera. In IOL fixation, it is important to position the IOL accurately in the sclera. Furthermore, in IOL fixation, it is important to firmly fix the haptic, which is a part of the IOL (hereinafter, collectively referred to as the IOL for convenience), into the sclera.
[0005] The intraocular lens (IOL) is fixed within the sclera by a fixation device (e.g., surgical thread). The fixation device uses an injection needle to secure the IOL within the sclera. During this process, the needle must be precisely inserted and withdrawn at specific points on the conjunctiva. Specifically, in intrascleral IOL fixation, the needle must be precisely inserted and withdrawn at six specific points on the conjunctiva.
[0006] When performing intrascleral fixation of intraocular lenses after marking multiple specific points where the injection needle is inserted and withdrawn using measuring tools such as a protractor or ruler, the surgical time increases significantly. Furthermore, when using measuring tools such as a protractor or ruler, the specific points where the injection needle is inserted and withdrawn are marked inaccurately, preventing the intraocular lens from being fixed in the correct position. Furthermore, when marking specific points using measuring tools, the eye may not be fixed and may continue to move, making it difficult to accurately mark the desired points. This problem is exacerbated by the fact that minimizing eye movement is very difficult for the patient to achieve voluntarily. Furthermore, when marking specific points using measuring tools, the patient's eye may be damaged when the measuring tool or the marking device that marks the specific points comes into contact with it, resulting in secondary damage.
[0007] The present invention aims to provide a marker capable of performing efficient surgery and a marking device including the same.
[0008] In addition, the present invention aims to provide a marker capable of accurately marking a specific point of an eye requiring surgery and a marking device including the marker.

[0057] A marking device according to one embodiment of the present invention can be used in a surgery to fix an artificial lens within the sclera (hereinafter, intrascleral intraocular lens fixation) in a patient with a dislocated intraocular lens, such as a cataract patient. However, the present invention is not limited thereto, and the marking device according to one embodiment can be used in various surgeries involving marking on the eye to treat ocular diseases. Hereinafter, for the convenience of understanding, a case in which the marking device according to one embodiment is used in intrascleral intraocular lens fixation will be described in detail with reference to the attached drawings as an example.
[0058] Figure 1 is a cross-sectional view schematically showing an eye in which the present invention is used.
[0059] The eyeball illustrated in Fig. 1 is a schematic representation. That is, the relative sizes and contact positions between the eyeball illustrated in Fig. 1 and the marking device described below are schematically illustrated. Furthermore, the relative sizes and positions of the tissues included in the eyeball illustrated in Fig. 1 may differ somewhat from those of an actual eyeball.
[0060] Referring to FIG. 1, the eyeball (100) may be composed of a sclera (20), a conjunctiva (30), a cornea (40), and an artificial lens (60). Intrascleral fixation of an artificial lens may be performed by inserting an artificial lens (60) into the eyeball and fixing the artificial lens (60) within the sclera (20). In the present specification, fixing the artificial lens (60) within the sclera (20) may be understood to mean fixing a haptic, etc., which is a part of the artificial lens (60), within the sclera (20).
[0061] The artificial lens (60) can be fixed within the sclera (20) by means of medical thread, etc. More specifically, the medical thread, etc. connects the artificial lens (60) located within the eyeball (100) and the sclera (20) by passing through the conjunctiva (30). In order for the artificial lens (60) to be fixed at an accurate position within the sclera (20), the position at which the injection needle (not shown) connected to the medical thread, etc. is introduced and / or withdrawn into the eyeball is important. To this end, the marking device (200) described below marks the position at which the injection needle (not shown) is introduced and / or withdrawn at a plurality of specific points on the conjunctiva (30) in advance. An injection needle (not shown) connected to a medical thread, etc., is inserted into the inside of the eyeball (100) through a specific point indicated, fixes the artificial lens (60) and the cornea (20) located inside the eyeball (100) to each other, and then is withdrawn to the outside of the eyeball (100) through another specific point indicated, thereby performing intrascleral fixation of the artificial lens.
[0062] Fig. 2 is a perspective view showing a marking device according to one embodiment. Fig. 3 is a side view showing a marking device according to one embodiment. Fig. 4 is a schematic drawing showing a top view of a body and a marking unit according to one embodiment. Fig. 5 is an enlarged view schematically showing a top view of a marking unit according to one embodiment. Fig. 6 is an enlarged view schematically showing a front view of a marking unit according to one embodiment.
[0063] Hereinafter, a marking device according to one embodiment of the present invention will be described in detail with reference to FIGS. 1 to 6.
[0064] As described above, the marking device (200) according to one embodiment can make a mark at a specific point on the eyeball (100) by coming into contact with the eyeball (100). For example, the marking device (200) can make a mark at a specific point on the conjunctiva (30). The mark may be a specific point where an injection needle (not shown) is inserted and / or withdrawn to fix the artificial lens (60) within the sclera (20) in intrascleral fixation of an artificial lens.
[0065] A marking device (200) according to one embodiment may include a body (210), a connecting portion (230), a grip portion (250), and a marking portion (300).
[0066] The body (210) may be formed generally in a ring shape. For example, the body (210) may be formed in a ring shape with one portion protruding laterally. A connecting groove (211) may be formed in the protruding portion of the body (210) to which a connecting portion (230) to be described later is coupled. The body (210) may have a constant thickness. In addition, the material of the body (210) may include stainless steel. The diameter of the body (210) may be approximately 11 mm to 13 mm. More specifically, the inner diameter of the body (210) may be approximately 11 mm to 12 mm, and the outer diameter of the body (210) may be approximately 12 mm to 13 mm. This is to efficiently perform intrascleral fixation of the intraocular lens by matching the diameter of the body (210) with the diameter of the intraocular lens (60) when viewed from above.
[0067] The connecting portion (230) connects the body (210) and the grip portion (250) described below. The connecting portion (230) includes a first connecting portion (231) and a second connecting portion (232). The first connecting portion (231) may have a generally rod shape. The first connecting portion (231) is connected to the body (210) generally vertically. More specifically, one end of the first connecting portion (231) may be inserted into a connecting groove (211) formed in a protruding portion of the body (210) to be connected to the body (210). The second connecting portion (232) may have a generally rod shape.
[0068] One end of the second connecting portion (232) is coupled with the first connecting portion (231). The other end of the second connecting portion (232) is coupled with the grip portion (250). The second connecting portion (232) may have a shape in which the width thereof increases from the first connecting portion (231) toward the grip portion (250). In addition, the longitudinal direction of the second connecting portion (232) may be inclined with respect to the longitudinal direction of the first connecting portion (231). For example, the longitudinal direction of the second connecting portion (232) may be inclined upward in a direction toward the side of the body (210). Accordingly, the connecting portion (230) may have an overall curved shape.
[0069] The grip portion (250) may be formed in a generally rod shape. For example, the cross-section of the grip portion (250) may have a rectangular shape. However, the present invention is not limited thereto, and the cross-section of the grip portion (250) may be deformed into various shapes. The grip portion (250) is coupled to the connecting portion (230). More specifically, one end of the grip portion (250) is coupled to the second connecting portion (232). Accordingly, the grip portion (250) is coupled to the body (210) via the connecting portion (230). The longitudinal direction of the grip portion (250) may be generally parallel to the longitudinal direction of the second connecting portion (232). That is, the longitudinal direction of the grip portion (250) may be inclined upward with respect to the body (210).
[0070] A grip protrusion (251) may be formed on the upper and lower surfaces of the grip portion (250). The grip protrusion (251) may be a groove. According to one embodiment, the grip protrusion (251) may be formed only on a specific portion of the upper and lower surfaces of the grip portion (250). However, the present invention is not limited thereto, and the grip protrusion (251) may be formed over the entire upper and lower surfaces of the grip portion (250). Unlike the foregoing, the grip protrusion (251) may be formed only on the upper surface among the upper and lower surfaces of the grip portion (250).
[0071] Due to the inclined longitudinal direction of the second connecting portion (232) and the grip portion (250), it can help secure the operator's field of vision when performing intrascleral fixation of an artificial lens using the marking device (200). That is, since the connecting portion (230) and the grip portion (250) can minimize obstruction of the operator's field of vision, efficient intrascleral fixation of an artificial lens can be performed using the marking device (200). In addition, due to the grip protrusion (251) described above, the operator's grip strength for the marking device (200) is improved, thereby minimizing slipping of the marking device (200) from the operator.
[0072] The first connecting portion (231) and the second connecting portion (232) described above may be formed integrally. In addition, the connecting portion (230) and the grip portion (250) described above may be formed integrally. In addition, unlike the above, the connecting groove (211) is not formed in the body (210), and the body (210), the connecting portion (230), and the grip portion (250) may be formed integrally.
[0073] According to one embodiment, a marking portion (300) may include a protruding body (310), a first marking portion (330), and a second marking portion (350).
[0074] The protruding body (310) is coupled to the body (210). In one embodiment, the protruding body (310) may be integrally coupled to the body (210). The material of the protruding body (310) may include stainless steel. The protruding body (310) protrudes laterally from the body (210). The thickness of the protruding body (310) may be the same as the thickness of the body (210). The upper surface of the protruding body (310) may be positioned at a height corresponding to the upper surface of the body (210), and the lower surface of the protruding body (310) may be positioned at a height corresponding to the lower surface of the body (210). The protruding body (310) may be formed in a generally 'ㄱ' shape. A plurality of protruding bodies (310) may be provided. For example, two protruding bodies (310) may be provided. The two protruding bodies (310) may have a symmetrical structure with respect to the center (C) of the body (210). For example, the two protruding bodies (310) may have a point-symmetrical structure with respect to the center (C) of the body (210). In addition, the two protruding bodies (310) may have a line-symmetrical structure with respect to an imaginary line connecting the connection groove (211) and the center (C) of the body (210). The above-described connection groove (211) and one of the protruding bodies (310) may be spaced apart at 90 degrees counterclockwise with respect to the center (C) of the body (210) when viewed from above, and the connection groove (211) and the other protruding body (310) may be spaced apart at 90 degrees clockwise with respect to the center (C) of the body (210) when viewed from above. In addition, one protruding body (310) may be spaced 180 degrees apart from another protruding body (310) when viewed from above and may be symmetrical. That is, one protruding body (310), a connecting groove (221), and another protruding body (310) may be sequentially arranged along the circumferential direction of the body (210) when viewed from above, but may be spaced 90 degrees apart from each other.
[0075] The first marking portion (330) and the second marking portion (350) may each include a plurality of markers. The plurality of markers may each contact the conjunctiva (30) to mark the conjunctiva (30) for performing intrascleral fixation of an artificial lens. As described above, the first marking portion (330) and the second marking portion (350) have a symmetrical structure with respect to the body (210) and are mostly formed of the same or similar structures. Therefore, the following description will focus on the first marking portion (330).
[0076] The first marking section (330) may include a first marker (331), a second marker (332), and a third marker (333).
[0077] Each of the markers (331, 332, 333) may generally have a rod shape. The cross-section of each of the markers (331, 332, 333) may have a circular shape. However, this is not limited to this, and the cross-section of each of the markers (331, 332, 333) may of course be transformed into various shapes other than a circular shape.
[0078] The ends of each of the markers (331, 332, 333) come into contact with the conjunctiva (30). The ends of each of the markers (331, 332, 333) are formed to be round. When performing intrascleral fixation of an artificial lens, surgical ink or the like is applied to the ends of each of the markers (331, 332, 333), and then each of the markers (331, 332, 333) is brought into contact with the conjunctiva (30) to mark the conjunctiva (30) for intrascleral fixation of an artificial lens.
[0079] The first marker (331) is coupled to the body (210). More specifically, the first marker (331) is coupled so as to protrude downward from the lower end of the body (210). According to one embodiment, the first marker (331) may be coupled to the body (210) by being inserted into a coupling groove (not shown) formed in the body (210). However, the present invention is not limited thereto, and the first marker (331) may be integrally formed at the lower end of the body (210) and protrude downward from the lower end of the body (210).
[0080] The second marker (332) and the third marker (333) are each coupled to the protruding body (310). More specifically, the second marker (332) and the third marker (333) are each formed to protrude downward from the bottom of the protruding body (310). According to one embodiment, the second marker (332) and the third marker (333) may be each inserted into a coupling groove (not shown) formed in the protruding body (310) to be coupled to the protruding body (310), or may be integrally formed at the bottom of the protruding body (310). For the sake of convenience of understanding, an example will be described below in which the first marker (331) is inserted into a coupling groove (not shown) formed in the body (210), and the second marker (332) and the third marker (333) are each inserted into a coupling groove (not shown) formed in the protruding body (310).
[0081] The first marker (331) and the second marker (332) are respectively positioned on the first virtual line (L1) when viewed from above. In addition, the second marker (332) and the third marker (333) are respectively positioned on the second virtual line (L2) when viewed from above. The first virtual line (L1) passes through the center (C) of the body (210), the first marker (331), and the second marker (332), when viewed from above. The second virtual line (L2) may be perpendicular to the first virtual line (L1) when viewed from above. In addition, the second virtual line (L2) passes through the second marker (332) and the third marker (333), when viewed from above.
[0082] The first marker (331) may be positioned to be spaced apart from the second marker (332) by a first distance (D1) when viewed from above. For example, the first distance (D1) may be 2 mm. In addition, the second marker (332) may be positioned to be spaced apart from the third marker (333) by a second distance (D2) when viewed from above. For example, the second distance (D2) may be 2 mm. That is, when viewed from above, the first marker (331) and the second marker (332) may be positioned to be spaced apart horizontally by a distance of 2 mm, and the second marker (332) and the third marker (333) may be positioned to be spaced apart vertically by a distance of 2 mm.
[0083] In addition, the distance between the first marker (331) and the center (C) of the body (210) may be shorter than the distance between the second marker (332) and the center (C) of the body (210). That is, the first marker (331) is positioned closer to the center (C) of the body (210) than the second marker (332). In addition, the distance between the second marker (332) and the center (C) of the body (210) may be shorter than the distance between the third marker (333) and the center (C) of the body (210). That is, the second marker (332) is positioned closer to the center (C) of the body (210) than the third marker (333).
[0084] In one embodiment, the length of the first marker (331) is shorter than the length of the second marker (332). In addition, the length of the first marker (331) is shorter than the length of the third marker (333). In addition, the lengths of the second marker (332) and the third marker (333) may be the same. More specifically, the length of the first marker (331) protruding downward from the lower surface of the body (210) is shorter than the lengths of each of the second marker (332) and the third marker (333) protruding downward from the lower surface of the protruding body (310). For example, the difference in protruding length between the first marker (331), the second marker (332) and the third marker (333) may correspond to the difference in length between the relative center of the eyeball (100) and the relative edge of the eyeball (100) according to the curvature angle of the eyeball (100).
[0085] As described above, each of the markers (331, 332, 333) is positioned at a different distance from the center (C) of the body (210). If the protruding lengths between the markers (331, 332, 333) are all the same, when the eyeball (100) and the markers (331, 332, 333) come into contact with each other, the curved eyeball (100) may be damaged. In particular, the first marker (331) closest to the center (C) of the body (210) may come into deep contact with the surface of the eyeball (100) and cause damage to the eyeball (100). In contrast, the third marker (333) located farthest from the center (C) of the body (210) may not be able to make a mark on the conjunctiva (30) because it may not be able to make a mark on the surface of the eyeball (100). Accordingly, by making the protruding lengths between the markers (331, 332, 333) different, when performing intrascleral fixation of an artificial lens, damage to the eyeball (100) caused by the markers (331, 332, 333) due to the curvature angle of the eyeball (100) can be minimized, and an accurate mark can be made on the conjunctiva (30).
[0086] Due to the rounded structure of the ends of each of the markers (331, 332, 333) described above, when the markers (331, 332, 333) and the conjunctiva (30) come into contact with each other, damage to the conjunctiva (30) can be minimized. Accordingly, secondary damage due to damage to the patient's eye can be prevented when performing intrascleral fixation of an artificial lens. In addition, since a plurality of markers come into contact with the patient's eye (e.g., conjunctiva (30)) at once, intrascleral fixation of an artificial lens can be performed more quickly. Accordingly, the time required for the surgery can be shortened, thereby minimizing surgical fatigue of the patient. In addition, since a plurality of markers are spaced apart from each other at the precise points where the injection needle is inserted and / or withdrawn, an accurate mark can be made at the required point with a single mark. Accordingly, the artificial lens (60) can be precisely fixed at the required point within the eye, thereby improving the completeness of the intrascleral fixation of the artificial lens.
[0087] In the above-described example, the first marking unit (330) is described as including a first marker (331), a second marker (332), and a third marker (333), but is not limited thereto. For example, the first marking unit (330) may include one marker or two markers. In addition, the first marking unit (330) may further include N markers (N is a natural number greater than or equal to 4).
[0088] Although not shown, according to another embodiment of the present invention, the length of the first marker (331) is shorter than the lengths of the second marker (332) and the third marker (333). In addition, the second marker (332) may be shorter than the length of the third marker (333). More specifically, the length of the first marker (331) protruding downward from the lower surface of the body (210) is shorter than the lengths of each of the second marker (332) and the third marker (333) protruding downward from the lower surface of the protruding body (310). In addition, the length of the second marker (332) protruding downward from the lower surface of the protruding body (310) may be shorter than the length of the third marker (333) protruding downward from the lower surface of the protruding body (310). The difference in protruding length between the first marker (331) and the second marker (332) may correspond to the difference in length between the relative center of the eye (100) and the relative edge of the eye (100), which is caused by the difference in the distance of the first marker (331) and the second marker (332) from the center (C) of the body (210). The difference in protruding length between the second marker (332) and the third marker (333) is also as described above.
[0089] In addition, when N markers (N is a natural number greater than or equal to 4) are provided in the marking section, the length difference between each marker may vary depending on the distance from the center of the body (210). For example, when viewed from above, a marker that is closer to the center of the body (210) may have a shorter vertical length than a marker that is relatively farther from the center of the body (210).
[0090] According to the marking device (200) according to another embodiment of the present invention described above, damage to the eyeball (100) can be prevented more efficiently, and marking can be made more efficiently and accurately on the conjunctiva (30), thereby further improving the completion rate of intrascleral fixation of an artificial lens.
[0091] The detailed description above is illustrative of the present invention. Furthermore, the above description illustrates and describes preferred embodiments of the present invention, and the present invention can be used in various other combinations, modifications, and environments. In other words, 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 embodiments illustrate the best possible state for implementing the technical idea of the present invention, and various modifications required for specific application fields and uses of the present invention are also possible. Therefore, the detailed description of the invention above is not intended to limit the present invention to the disclosed embodiments. Furthermore, the appended claims should be construed to include other embodiments.
[0092] The present invention relates to a conjunctival marker and a marking device including the same, and more particularly, to a conjunctival marker and a marking device including the same for indicating a point at which an injection needle is inserted or withdrawn in a fixation technique for fixing a portion of an artificial lens within the cornea.
