Description

[Technical Field]

[0001] FIELD OF THE DISCLOSURE The present disclosure relates to a viscoelastic syringe handling surgical instrument and surgical instrument set. [Background technology]

[0002] The transparent lens in the human eye plays an important role in focusing an image of an object. This transparent lens can become blurred due to aging, inflammation in the eye, or trauma. This can lead to cataracts, a type of eye disease. When cataracts progress to the point where they cause inconvenience in daily life, medications are no longer effective and surgery must be considered.

[0003] Cataract surgery involves drilling a small hole in the pupil or white of the eye, inserting an ultrasonic instrument to remove the cataractous lens, and then inserting a permanent artificial lens in its place. Specifically, the cornea is incised, a viscoelastic of a predetermined viscosity is injected between the cornea and the lens, and a circular incision is made in the anterior capsule (the anterior part of the lens capsule) called a continuous curvilinear capsulorrhexis (CCC). During this process, the viscoelastic is injected between the cornea and the lens, creating a predetermined space to facilitate the insertion of surgical instruments and an artificial lens. The cataractous lens is then aspirated using ultrasound while the viscoelastic is injected through the incision in the anterior capsule. During this process, the viscoelastic prevents the lens capsule from shrinking due to lack of fluid after the anterior capsule incision and maintains the capsule's shape. The intraocular lens is then inserted and attached to the capsular bag, and the viscoelastic material may be aspirated and removed before or after insertion of the intraocular lens.

[0004] Generally, viscoelastic materials are provided by being stored or filled in a syringe. The practitioner injects the viscoelastic material using the syringe containing the viscoelastic material. Because the viscoelastic material has high viscosity to maintain the shape of the lens capsule, handling is required to move the viscoelastic material during the procedure. For example, handling of the viscoelastic material is performed using a needle-shaped instrument called a chopper. Summary of the Invention [Problem to be solved by the invention]

[0005] However, in conventional methods, when handling of the viscoelastic material is required during injection into the lens capsule, an injection instrument for injecting the viscoelastic material is withdrawn from the lens capsule, and a handling instrument for handling the viscoelastic material is then advanced into the lens capsule. After handling of the viscoelastic material is completed, the handling instrument is withdrawn, and the injection instrument is re-advanced. Repeated advancement and retraction of the injection and handling instruments in this manner can result in astigmatism. Furthermore, alternate advancement and retraction of the injection and handling instruments can lengthen the surgical time.

[0006] Embodiments of the present disclosure improve upon or overcome at least some of the problems associated with conventional viscoelastic injection and handling devices by providing a viscoelastic syringe-handling surgical device that can both inject and handle viscoelastic material while the surgical device is inserted.

[0007] Additionally, some embodiments provide a viscoelastic syringe handling surgical tool set including a syringe and a viscoelastic syringe handling surgical tool. [Means for solving the problem]

[0008] An embodiment according to one aspect of the present disclosure relates to a surgical instrument for handling a viscoelastic syringe, which includes a main body configured to be coupled in a front-to-rear direction with a syringe containing viscoelastic material, a first gripping portion formed to protrude from the main body in one direction perpendicular to the front-to-rear direction, and a second gripping portion formed to protrude from the main body in a direction opposite to the one direction.

[0009] In one embodiment, the main body may include a front plate having a first through hole formed therein so that a syringe can pass through in the front-rear direction, a rear plate having a second through hole formed therein so that a syringe can pass through in the front-rear direction, a hollow portion that connects the first through hole and the second through hole in the front-rear direction, a first side wall that is arranged in one direction based on the hollow portion, connects the front plate and the rear plate, and has the first gripping portion fixed thereto, and a second side wall that is arranged in the opposite direction based on the hollow portion, connects the front plate and the rear plate, and has the second gripping portion fixed thereto.

[0010] In one embodiment, the front plate and the back plate may be positioned alongside one another, and the first side wall and the second side wall may be positioned alongside one another.

[0011] In one embodiment, the hollow portion may be open to one side and to a side perpendicular to the front-to-rear direction.

[0012] In one embodiment, the first gripping portion may include a first gripping ring having a first through hole formed on a side perpendicular to one side and the front-to-back direction so that a finger can be inserted therethrough; a second gripping ring connected to the rear of the first gripping ring and having a second through hole formed on the side so that a finger can be inserted therethrough; and a third gripping ring connected to the rear of the second gripping ring and having a third through hole formed on the side so that a finger can be inserted therethrough.

[0013] In one embodiment, the third through-hole may be smaller than the first and second through-holes.

[0014] In one embodiment, the second gripping portion includes a fourth gripping ring having a fourth through hole formed on the side to allow insertion of a finger, and the fourth through hole may be larger than the first through hole, the second through hole, and the third through hole.

[0015] In one embodiment, the fourth gripping ring may include a forward extension defining a forward boundary of the fourth through hole, extending in opposite directions from the body and having a flat front end surface and a flat rear end surface, and a rearward extension defining a rearward boundary of the fourth through hole, extending in opposite directions from the body and having a flat front end surface and a flat rear end surface.

[0016] In one embodiment, the body, the first gripping portion, and the second gripping portion may be integrally formed.

[0017] An embodiment according to another aspect of the present disclosure relates to a surgical tool set for handling a viscoelastic material syringe. The surgical tool set for handling a viscoelastic material syringe according to an exemplary embodiment includes a main body having a syringe containing a viscoelastic material, a front plate having a first through-hole at its front end to allow the syringe to pass through in the front-rear direction, and a rear plate having a second through-hole at its rear end and spaced apart from the front plate, a first gripping portion formed to protrude from the main body in one direction perpendicular to the front-rear direction, and a second gripping portion formed to protrude from the main body in the opposite direction to the one direction.

[0018] In one embodiment, the fourth gripping ring may include a forward extension defining a forward boundary of the fourth through hole, extending in opposite directions from the body and having a flat front end surface and a flat rear end surface, and a rearward extension defining a rearward boundary of the fourth through hole, extending in opposite directions from the body and having a flat front end surface and a flat rear end surface. [Effects of the Invention]

[0019] According to various embodiments of the present disclosure, a surgical instrument for handling a viscoelastic material syringe has a syringe connected to a main body and first and second gripping portions formed to protrude in both directions from the main body, allowing the surgeon to inject or handle the viscoelastic material while holding at least a portion of the syringe connected to the surgical instrument in a state where it is injected into the lens capsule. Therefore, since there is no need to alternately advance and retract separate instruments for injecting and handling the viscoelastic material, the occurrence of astigmatism can be prevented or suppressed. Furthermore, the time required for surgery can be shortened. [Brief explanation of the drawings]

In addition, in the following description of the embodiments, repeated descriptions of identical or corresponding components may be omitted. However, omission of a description of a component does not mean that the component is not included in a certain embodiment.

[0035] FIG. 1 is a perspective view illustrating a surgical instrument for handling a viscoelastic syringe according to one embodiment of the present disclosure.

[0036] As shown in FIG. 1, a surgical instrument 1000 for handling a viscoelastic syringe (hereinafter simply referred to as the "surgical instrument") according to one embodiment of the present disclosure includes a main body 100, a first gripping portion 200, and a second gripping portion 300. The main body 100 is configured so that a syringe 400 (see FIGS. 4 to 7, described below) containing or filled with a viscoelastic material is coupled to the main body 100 in a forward-rearward (FD-RD) direction. For example, the syringe 400 may be coupled to the main body 100 in a direction from the rear (RD) to the front (FD). The first gripping portion 200 is formed to protrude from the main body 100 in a first side direction (FS), which is one side direction perpendicular to the forward-rearward (FD-RD) direction. The second gripping portion 300 is formed to protrude from the main body 100 in a second side direction (SS), which is the opposite direction to the one side direction.

[0037] As described above, the syringe 400 is connected to the main body 100, and the first and second gripping portions 200 and 300 are formed to protrude in both directions of the main body 100 (i.e., the first side direction (FS) and the second side direction (SS)). This allows the surgeon to inject or handle the viscoelastic material while holding at least a portion of the syringe 400 connected to the surgical instrument 1000 injected into the lens capsule. Therefore, there is no need to alternately advance and retract different instruments for injecting and handling the viscoelastic material, which can prevent or suppress the occurrence of astigmatism. Furthermore, the time required for surgery can be shortened.

[0038] In one embodiment, the main body 100, the first gripping portion 200, and the second gripping portion 300 may be integrally formed. For example, the main body 100, the first gripping portion 200, and the second gripping portion 300 may be made of the same metal material. Furthermore, the main body 100, the first gripping portion 200, and the second gripping portion 300 may be manufactured by casting or die casting to have shapes according to various embodiments described below.

[0039] Fig. 2 is a front view showing the viscoelastic syringe handling surgical instrument shown in Fig. 1. Fig. 3 is a cross-sectional view taken along line III-III shown in Fig. 1.

[0040] In one embodiment, as shown in FIGS. 2 and 3, the body 100 may include a front plate 110, a rear plate 120, a hollow portion 130, a first side wall 140, and a second side wall 150.

[0041] A first through hole 111 is formed in the front plate 110 so that the syringe 400 passes through in the front-rear direction (FD-RD). For example, the inner diameter of the first through hole 111 may have a size corresponding to the outer diameter of the barrel 410 of the syringe 400. Therefore, when the syringe 400 is attached to the surgical instrument 1000, the syringe 400 is prevented from moving relative to the surgical instrument 1000, allowing the surgeon to perform precise surgery.

[0042] A second through hole 121 is formed in the rear plate 120 so that the syringe 400 passes through in the front-rear direction (FD-RD). The rear plate 120 may be thicker than the front plate 110. In one embodiment, the front plate 110 and the rear plate 120 may be arranged side by side. The inner diameter of the second through hole 121 may correspond to the outer diameter of the barrel 410 of the syringe 400. In addition, since the barrel 410 of the syringe 400 generally has the same outer diameter along the front-rear direction (FD-RD), the inner diameter of the second through hole 121 may be formed to be the same as the inner diameter of the first through hole 111. Therefore, when the syringe 400 is attached to the surgical instrument 1000, the syringe 400 is prevented from moving relative to the surgical instrument 1000, allowing the surgeon to perform precise surgery.

[0043] The hollow portion 130 communicates the first through hole 111 and the second through hole 121. In one embodiment, the hollow portion 130 is open in a third side direction (TS), which is a side direction perpendicular to the first side direction (FS) and the second side direction (SS). For example, the hollow portion 130 may be formed by configuring the first side wall 140 and the second side wall 150 so that they are not connected to each other in the first side direction (FS) or the second side direction (SS). In other words, the empty space formed between the first side wall 140 and the second side wall 150 may be understood as the hollow portion 130. When the syringe 400 is coupled to the surgical instrument 1000, the barrel 410 of the syringe 400 is located in the hollow portion 130. Therefore, while the syringe 400 is coupled to the surgical instrument 1000 and the viscoelastic material is being injected, the remaining amount of the viscoelastic material filled or stored inside the barrel 410 can be visually confirmed by the surgeon through the hollow portion 130. Furthermore, by forming the hollow portion 130, the overall weight of the surgical instrument 1000 can be reduced, thereby reducing the surgeon's fatigue.

[0044] The first side wall 140 is disposed in a first side direction (FS), which is one side direction based on the hollow portion 130, and connects the front plate 110 and the rear plate 120 in the front-rear direction (FD-RD). A first gripper 200 is fixed to the first side wall 140. A corner where the first side wall 140 meets the front plate 110 and a corner where the first side wall 140 meets the rear plate 120 may have a rounded shape. The first side wall 140 may have a thickness thinner than the front plate 110 and the rear plate 120.

[0045] The second side wall 150 is disposed in a second side direction (SS), which is the opposite side direction of the hollow portion 130, and connects the front plate 110 and the rear plate 120 in the front-rear direction (FD-RD). A second gripper 300 is fixed to the second side wall 150. A corner where the second side wall 150 meets the front plate 110 and a corner where the second side wall 150 meets the rear plate 120 may have a rounded shape. The second side wall 150 may have a thinner thickness than the front plate 110 and the rear plate 120. In one embodiment, the first side wall 140 and the second side wall 150 may be disposed side by side.

[0046] In this embodiment, the front plate 110, the first side wall 140, the rear plate 120, and the second side wall 150 may form a substantially rectangular shape connected to each other in a clockwise direction on the front side as viewed from the third side direction (TS).

[0047] In one embodiment, first gripping portion 200 may include first gripping ring 210, second gripping ring 220, and third gripping ring 230. As an example, first gripping ring 210, second gripping ring 220, and third gripping ring 230 may be formed sequentially from front (FD) to rear (RD).

[0048] The first grip ring 210 has a first through hole 211 formed in a first side direction (FS) that is one side direction to allow insertion of a finger and in a third side direction (TS) that is a side perpendicular to the front-rear direction (FD-RD). For example, a ring finger 40 may be inserted into the first through hole 211. The first grip ring 210 has a shape of approximately " TIFF2025532691000002.tif44" shape, and the first through-hole 211 may have a shape of approximately " The file may have the shape "TIFF2025532691000003.tif44".

[0049] The second grip ring 220 is connected to the rear of the first grip ring 210, and has a second through hole 221 formed in the third side direction (TS) to allow insertion of a finger. For example, the middle finger 30 may be inserted into the second through hole 221. The second grip ring 220 may have a general "C" shape when viewed from the front, and the first through hole 211 may have a "C" shape corresponding to the shape of the first grip ring 210. In one embodiment, the second through hole 221 may be formed to have approximately the same size as the first through hole 211.

[0050] The third grip ring 230 is connected to the rear of the second grip ring 220, and has a third through-hole 231 formed in a third side direction (TS) so that a finger can be inserted. For example, the index finger 20 can be inserted into the third through-hole 231. The third grip ring 230 has a shape of approximately " TIFF2025532691000004.tif44" shape, and the third through-hole 231 may have a shape of approximately " TIFF2025532691000005.tif44”. In one embodiment, the third through-hole 231 may be smaller than the first through-hole 211 and the second through-hole 221.

[0051] In one embodiment, the second grip part 300 may include a fourth grip ring 310 having a fourth through hole 311 formed in a third side direction (TS) so that a finger can be inserted. For example, the thumb 10 may be inserted into the fourth through hole 311. The fourth grip ring 310 has a generally " TIFF2025532691000006.tif44", and the fourth through-hole 311 may have a shape roughly like " TIFF2025532691000007.tif44”. In this embodiment, the fourth through-hole 311 may be formed larger than the first through-hole 211, the second through-hole 221 and the third through-hole 231.

[0052] In one embodiment, the fourth gripping ring 310 may include a forward extension 312 and a rearward extension 313. The forward extension 312 defines a front boundary of the fourth through hole 311. The forward extension 312 extends from the main body 100 in a second side direction (SS) and has a flat front end surface 312a and a flat rear end surface 312b. The rearward extension 313 defines a rear boundary of the fourth through hole 311. The rearward extension 313 extends from the main body 100 in a second side direction (SS) and has a flat front end surface 313a and a flat rear end surface 313b. When the thumb 10 is inserted into the fourth through hole 311 for injection of the viscoelastic material (see FIG. 7 ), the forward extension 312 and the rearward extension 313 serve to support the inserted thumb 10 so that it does not move forward (FD) or backward (RD) relative to the surgical instrument 1000. When the little finger 50 is positioned in front of the fourth grip ring 310 for handling the viscoelastic material (see FIG. 6), the little finger 50 abuts against the front end surface of the front extension portion 312 and is supported by the front extension portion 312.

[0053] Fig. 4 is a perspective view of a surgical tool set for handling a viscoelastic syringe according to one embodiment of the present disclosure, and Fig. 5 is an exploded perspective view of the surgical tool set for handling a viscoelastic syringe shown in Fig. 4.

[0054] 4 and 5, in another aspect of the present disclosure, a surgical instrument set 2000 for handling a viscoelastic syringe according to one embodiment (hereinafter simply referred to as the "surgical instrument set") includes a syringe 400, a main body 100, a first grip portion 200, and a second grip portion 300. The main body 100, the first grip portion 200, and the second grip portion 300 according to this embodiment are the same as or similar to the main body 100, the first grip portion 200, and the second grip portion 300 according to the embodiment shown in FIGS. 1 to 3, so detailed description of these components will be omitted and the following description will focus on the syringe 400 and its related components.

[0055] The syringe 400 is filled with or stores a viscoelastic material. The syringe 400 is coupled to the main body 100 of the surgical instrument 1000 by passing through the second through-hole 121 of the rear plate 120 and the first through-hole 111 of the front plate 110 in that order from rear (RD) to front (FD). For example, the syringe 400 may include a barrel 410 in which the viscoelastic material is filled or stored, a plunger 420 that pressurizes the viscoelastic material, and a needle 430 from which the viscoelastic material is expelled. A thumb rest 421 is formed at the rear end of the plunger 420. The needle 430 includes a first pipe-shaped extension 431 extending in the front-rear direction (FD-RD) and a second pipe-shaped extension 432 bent at a predetermined angle from the first extension 431. The viscoelastic material is expelled from the tip of the second extension 432 as the plunger 420 moves forward and is injected into the lens capsule.

[0056] In one embodiment, the syringe 400 may include one or more flanges 440 protruding radially outward from the rear end. The flanges 440 are formed at the rear end of the barrel 410. In the embodiment shown in FIGS. 4 and 5, the flanges 440 are formed in a ring shape along the circumferential direction at the rear end of the barrel 410. However, two or more flanges may be formed spaced apart at equal intervals along the circumferential direction. The flanges 440 in this embodiment may be understood as finger flanges of a general syringe. In this embodiment, when the barrel 410 of the syringe 400 passes through the first through hole 111 and the second through hole 121, the front end surface 441 of the flanges 440 is configured to rest on the rear end surface 122 of the rear plate 120. Therefore, the practitioner can inject or handle the viscoelastic material by holding the first grip portion 200 and the second grip portion 300 instead of holding the flanges 440 with their fingers.

[0057] FIG. 6 is a perspective view schematically showing a first example of use of the surgical instrument set for handling a viscoelastic substance syringe shown in FIG.

[0058] 6 , to inject the viscoelastic material, the practitioner can grasp the surgical instrument set 2000 by inserting the ring finger 40 into the first through hole 211 of the first gripping ring 210, the middle finger 30 into the second through hole 221 of the second gripping ring 220, the index finger 20 into the third through hole 231 of the third gripping ring 230, positioning the little finger 50 on the front end surface 312a of the forward extension portion 312 of the first gripping ring 210, and positioning the thumb 10 on the thumb rest 421 of the plunger 420. In this state, the practitioner can inject the viscoelastic material by applying forward (FD) pressure to the thumb rest 421 of the plunger 420 with the thumb 10.

[0059] FIG. 7 is a perspective view schematically showing a second example of use of the surgical instrument set for handling a viscoelastic substance syringe shown in FIG.

[0060] As shown in FIG. 7 , to handle the viscoelastic material, the surgeon can grasp the surgical instrument set 2000 by inserting the thumb 10 into the fourth through-hole 311 of the fourth gripping ring 310 while holding the ring finger 40, middle finger 30, index finger 20, and little finger 50 in the position shown in FIG. 6 . In this state, the surgeon can handle the viscoelastic material. As another example of use when handling the viscoelastic material, the surgeon can handle the viscoelastic material while holding the ring finger 40, middle finger 30, index finger 20, and thumb 10 in the position shown in FIG. 7 and separating the little finger 50 from the first extension portion 431. In this way, by changing the position of the thumb 10, it is possible to switch between injecting and handling the viscoelastic material. As a result, the time required for surgery can be shortened.

[0061] Although the technical idea of ​​the present disclosure has been described above by way of some embodiments and examples shown in the accompanying drawings, it should be understood that various substitutions, modifications, and changes can be made without departing from the technical idea and scope of the present disclosure, which can be understood by those skilled in the art to which the present disclosure pertains. Furthermore, such substitutions, modifications, and changes should be considered to fall within the scope of the appended claims.
