Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and more specifically, to a goniosynechialysis device. Background Art

[0002] In the related art, glaucoma is the world's leading irreversible blinding eye disease. With the continuous development and innovation of glaucoma diagnosis and treatment technologies, glaucoma surgery has shifted from traditional filtering surgery with complex operations and relatively more complications to minimally invasive glaucoma surgery (MIGS) with simple operations and relatively fewer complications.

[0003] Goniosynechialysis (GSL) is an important technique in MIGS applied to PACG. Its purpose is to separate the adhesed goniosynechial structure and open the aqueous humor outflow channel. Currently, there is no dedicated surgical instrument for goniosynechialysis in clinical practice. Ophthalmologists often perform blind goniosynechialysis using viscoelastic agents in the anterior chamber, or use instruments such as iris repositors and phacoemulsification nucleus hooks for goniosynechialysis. However, no matter which alternative instrument is used, its holding angle, force application direction, iris grasping force, etc. cannot efficiently, minimally invasively, and conveniently complete goniosynechialysis, bringing many troubles to the clinic.

[0004] For example, using viscoelastic agents for goniosynechialysis has the following disadvantages: ① The goniosynechial cannot be directly visualized during the operation; ② The viscoelastic agent has a certain fluidity and insufficient acting force; ③ It is easy to remain and cause increased intraocular pressure; ④ The goniosynechialysis effect is uncertain.

[0005] Using an iris repositor has the following disadvantages: ① The instrument is relatively wide and has limited movement range in the anterior chamber; ② The instrument is flat and smooth, and it is not easy to apply force to the iris root; ③ Acting on the peripheral iris is prone to sliding, with low efficiency and poor effect.

[0006] Using a phacoemulsification nucleus hook has the following disadvantages: ① The head of the small hook is relatively sharp and is easy to damage the iris, causing tearing or bleeding; ② The width of the head of the small hook is narrow, and the separation range at one time is too small, resulting in low separation efficiency; ③ The long hook enters the anterior chamber in the horizontal position and is placed on the surface of the peripheral iris for separation, but it is relatively smooth and not easy to generate a grasping force, with low efficiency; ④ The force application direction of the wrist does not conform to human mechanics, making the surgical operation inconvenient; ⑤ The separation range of the goniosynechial to the right direction is insufficient, and the operation is more inconvenient.

[0007] Using an intraocular lens positioning hook has the following disadvantages: ① Although the head is round and blunt, due to the strong elasticity of the iris, the separation effect cannot be achieved; ② The same as the phacoemulsification nucleus hook.

[0008] Therefore, there is an urgent need to design a set of dedicated goniosynechialysis devices for direct visualization as an important practical tool for effective goniosynechialysis in glaucoma surgery. Summary of the Utility Model

[0036] Now, various exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0037] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present invention or its application or use.

[0038] Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods, and devices should be regarded as part of the description.

[0039] In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0040] It should be noted that: Similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0041] Next, the gonioseparator 100 according to the embodiments of the present invention will be specifically described with reference to the accompanying drawings.

[0042] As Figures 1 to 8 shown, the gonioseparator 100 according to the embodiments of the present invention includes: a handle part 10, at least one neck part 20, and at least one arc-shaped curved ring 30.

[0043] Specifically, each neck portion 20 is provided at an end of the handle portion 10. The neck portion 20 is designed in a long strip structure or in a bent structure. Each arc-shaped bent ring 30 is provided at one end of the corresponding neck portion 20 away from the handle portion 10 and is vertically arranged relative to the neck portion 20. At least one surface of the arc-shaped bent ring 30 is provided with a matte layer 31.

[0044] In other words, the gonioseparator 100 according to the embodiment of the present invention mainly consists of a handle portion 10, at least one neck portion 20 and at least one arc-shaped bent ring 30, and specifically may include but is not limited to the following several situations.

[0045] In the first situation, the gonioseparator 100 includes a handle portion 10, a neck portion 20 and an arc-shaped bent ring 30 that are connected in sequence.

[0046] In the second situation, the gonioseparator 100 includes a handle portion 10, two neck portions 20 and two arc-shaped bent rings 30. The two neck portions 20 are spaced apart and arranged at both ends of the handle portion 10, and an arc-shaped bent ring 30 is connected to one end of each neck portion 20 away from the handle portion 10.

[0047] The handle portion 10 can be straight, which is convenient for the user to hold and operate. The neck portion 20 can be in a long strip shape or in a bent shape. The long strip-shaped neck portion 20 and the straight handle portion 10 can be coaxially arranged. At least a part of the bent neck portion 20 and the handle portion 10 can form an angle. The arc-shaped bent ring 30 can be connected to one end of the neck portion 20 away from the handle portion 10.

[0048] For the convenience of description, the extending direction of the handle portion 10 can be defined as the first direction. When the neck portion 20 is designed in a long strip shape, the neck portion 20 extends along the first direction, and the extending direction of the connection line between the two farthest points on the arc-shaped bent ring 30 connected to the neck portion 20 can be perpendicular to the first direction. When the neck portion 20 is designed in a bent structure, a part of the neck portion 20 extends along the first direction, and another part of the neck portion 20 can extend along the second direction. There is an angle between the second direction and the first direction, and the extending direction of the connection line between the two farthest points on the arc-shaped bent ring 30 connected to the neck portion 20 can be perpendicular to the second direction.

[0049] Setting the neck portion 20 as a long strip structure or a bent structure can be applicable to incisional surgeries at different parts. The bent structure is applicable to the corneal incision above the nose, which can effectively avoid the occlusion of the eyelid and the speculum and the regulation of the eye position. The long strip structure is applicable to the temporal incision, and can directly enter the anterior chamber under the direct vision of the microscope to reach the contralateral gonioscope for operation.

[0050] In Case 1, the gonioseparator 100 includes only one arc-shaped bent ring 30, and a frosted layer 31 may be provided on the surface of the arc-shaped bent ring 30. In Case 2, the gonioseparator 100 includes two arc-shaped bent rings 30, and a frosted layer 31 may be provided on the surface of one of the arc-shaped bent rings 30, or frosted layers 31 may be provided on the surfaces of both arc-shaped bent rings 30.

[0051] Thus, for the gonioseparator 100 according to the embodiment of the present invention, by providing the arc-shaped bent ring 30 in the gonioseparator 100, the arc-shaped bent ring 30 can better fit the curvature of the corneal limbus, making the separation position deeper and the separation more thorough, suitable for large-range separation to the left and right sides, and the structure of the arc-shaped bent ring 30 is more suitable for separating the gonioscope with slight adhesion, risk of bleeding or greater iris damage, avoiding bleeding problems. At the same time, by providing the frosted layer 31 on the surface of at least one arc-shaped bent ring 30, the friction can be increased, and an acting force can be effectively applied to the iris without damaging the iris tissue, so that the gonioseparator 100 has higher safety and stronger operability.

[0052] According to an embodiment of the present invention, one end of the arc-shaped bent ring 30 is connected to the neck 20, and the other end of the arc-shaped bent ring 30 is a free end.

[0053] That is to say, an L-shaped design can be formed between the arc-shaped bent ring 30 and the end of the neck 20 away from the handle portion 10. Thus, it is convenient for the gonioseparator 100 to enter and exit the corneal incision, suitable for smaller incisions, and reducing surgical source damage.

[0054] According to some other embodiments of the present invention, as Figure 2 and Figure 6 shown, the numbers of the neck 20 and the arc-shaped bent ring 30 are both two. The two necks 20 are the first neck 20a and the second neck 20b respectively, and the two arc-shaped bent rings 30 are the first arc-shaped bent ring 30a and the second arc-shaped bent ring 30b respectively. The first arc-shaped bent ring 30a, the first neck 20a, the handle portion 10, the second neck 20b and the second arc-shaped bent ring 30b are connected in sequence.

[0055] By providing one neck 20 and a corresponding arc-shaped bent ring 30 at each end of a single handle portion 10, it is beneficial to improve the integration of the gonioseparator 100, increase the functions that a single gonioseparator 100 can achieve, and reduce the waste of medical consumables.

[0056] In some specific embodiments of the present invention, the free ends of the first arc-shaped bent ring 30a and the second arc-shaped bent ring 30b extend in opposite directions, which is convenient for doctors to use. As Figure 2 shown, the first arc-shaped bent ring 30a above the handle portion 10 may extend towards the left, and the second arc-shaped bent ring 30b below the handle portion 10 may extend towards the right.

[0057] According to some alternative embodiments of the present utility model, when the first neck portion 20a and the second neck portion 20b are both designed as bent structures, the bent structures of the first neck portion 20a and the second neck portion 20b face opposite directions, and a frosted layer 31 is provided on the surfaces of both the first arc-shaped bent ring 30a and the second arc-shaped bent ring 30b.

[0058] Specifically, as Figure 7 shown, the first neck portion 20a above the handle portion 10 can be bent towards the right, and the second neck portion 20b below the handle portion 10 can be bent towards the left, which can make it more convenient for doctors to use and improve the operating feel. In the gonioseparator 100, frosted layers 31 are provided on the surfaces of both arc-shaped bent rings 30. For a corneal incision above the nose, it is more difficult to apply force when using the gonioseparator 100 with a neck portion 20 having a bent structure. Therefore, providing frosted layers 31 on both arc-shaped bent rings 30 can effectively apply a force to the iris.

[0059] According to some other embodiments of the present utility model, when the first neck portion 20a and the second neck portion 20b are both designed as strip-shaped structures, as Figures 2 to 4 shown, a frosted layer 31 is provided on the surface of the first arc-shaped bent ring 30a, and the surface of the second arc-shaped bent ring 30b is smooth.

[0060] The first arc-shaped bent ring 30a with the frosted layer 31 is beneficial to increasing the friction force and effectively applying a force to the iris without damaging the iris tissue. The second arc-shaped bent ring 30b with a smooth surface is beneficial to reducing the risk of bleeding and iris damage.

[0061] In some specific embodiments of the present utility model, the total length L5 of the arc-shaped bent ring 30 is 1.2 mm to 2.0 mm, and the diameter of the arc-shaped bent ring 30 is 0.2 mm to 0.4 mm. This is beneficial to reducing the risk of bleeding and iris damage. Preferably, the total length L5 of the arc-shaped bent ring 30 is 1.6 mm and the diameter is 0.3 mm.

[0062] According to some alternative embodiments of the present utility model, a bent portion is provided on the neck portion 20 designed as a bent structure, and the bending angle α of the bent portion is 130° to 140°, which can effectively avoid the occlusion of the eyelid and the speculum and the regulation of the eye position.

[0063] Preferably, the bending angle α of the bent portion is 135°.

[0064] According to some other embodiments of the present utility model, the bending portion divides the neck 20 into a straight portion 21 and a curved portion 22. The straight portion 21 is connected to the handle portion 10, and the curved portion 22 is connected to the arc-shaped bent ring 30. The length L3 of the straight portion 21 is 14 mm to 16 mm, the length L4 of the curved portion 22 is 10 mm to 12 mm, and the length L2 of the neck 20 designed in a long strip shape is 20 mm to 26 mm, which is beneficial to improving the operation feel and facilitating the doctor's operation.

[0065] Preferably, the length L3 of the straight portion 21 is 15 mm, the length L4 of the curved portion 22 is 11 mm, and the length L2 of the neck 20 designed in a long strip shape is 24 mm.

[0066] In some specific embodiments of the present utility model, the diameter of the neck 20 is smaller than the diameter of the handle portion 10. The length L1 of the handle portion 10 is 80 mm to 100 mm. The middle of the handle portion 10 is designed in a cylindrical structure. A plurality of annular protrusions 11 are provided at intervals along the length direction of the handle portion 10 in the middle of the handle portion 10. The two ends of the handle portion 10 are designed in a conical structure.

[0067] Setting the diameter of the handle portion 10 to be larger can facilitate the doctor's grip, and setting the diameter of the neck 20 to be smaller can improve the operability. The length L1 of the handle portion 10 is 80 mm to 100 mm, which can have a good grip feel and avoid the influence of the length of the handle portion 10 being too long or too short on the use experience. The middle of the handle portion 10 is designed in a cylindrical structure, which better meets the requirements of ergonomics for the convenience of exerting force on the wrist and fingers. A plurality of annular protrusions 11 are provided in the middle of the handle portion 10, which can increase the friction when gripping. The two ends of the handle portion 10 are provided with a conical structure, which can facilitate better connection with the neck 20 with a smaller diameter.

[0068] Preferably, the length of the handle portion 10 is 90 mm.

[0069] Optionally, the handle portion 10, the neck 20, and the arc-shaped bent ring 30 are integrally formed, and preferably made of stainless steel material. The integrally formed structure setting is more conducive to mass production, and no other auxiliary tools are required, with better safety and operability. The stainless steel material is convenient for high-temperature disinfection and repeated use, thereby reducing the waste of medical consumables.
