Description

Technical Field

[0001] This application belongs to the field of medical technology, and in particular relates to implantable devices, implantable systems, and methods of using implantable systems. Background Technology

[0002] Aqueous humor drainage tubes are used for patients with high intraocular pressure. After implantation, one end of the tube is placed freely in the anterior chamber angle, and the other end is placed under the conjunctiva, forming a channel between the anterior chamber and the conjunctiva. This allows aqueous humor to drain from the anterior chamber to the subconjunctival space, lowering intraocular pressure. Aqueous humor drainage tube implantation procedures are generally divided into internal and external approaches. The surgeon will choose the appropriate approach based on their own habits and the patient's specific situation. The internal approach involves the needle penetrating the cornea, passing through the anterior chamber, and then through the trabecular meshwork and sclera to enter the subconjunctival space. The external approach involves the needle penetrating the conjunctiva, passing through the sclera and trabecular meshwork to enter the anterior chamber. The two approaches have different puncture depths, and usually require two different implantation systems to handle different situations. Summary of the Invention

When the switching member is configured to extend into the housing from the connection opening, at least a portion of the connecting shaft and the cam shaft are accommodated in the first and second switching grooves. At this time, rotating the switching member along the axis of the connecting shaft causes the cam shaft to rotate within the first and second switching grooves, driving the first and third seats to move along the first direction.

As the rotating wheel rotates, it can drive the push rod assembly to move away from the rotating wheel along a first direction, and drive the puncture needle assembly to move towards the rotating wheel along the first direction.

[0016] According to an embodiment of the first aspect of this application, a first groove and a second groove are respectively provided on the two end faces of the rotating wheel.

[0017] On the other hand, embodiments of this application also provide an implantation system, including the implantation device and implant as described above.

[0018] On the other hand, this application embodiment also provides a method of using an implantation system, applied to the implantation system as described above. The method of use includes: extending a switching member into the housing from the connection opening, with at least a portion of the connecting shaft and the cam shaft accommodated in the first switching groove and the second switching groove; rotating the switching member along the axis of the connecting shaft, with the cam shaft rotating in the first switching groove and the second switching groove; the cam shaft driving the first seat to move along a first direction, and the cam shaft driving the third seat to move along the first direction.

[0019] The implantation device according to this application embodiment is used for implanting an implant. The implantation device includes a housing, a push rod assembly, a puncture needle assembly, and a switching member. The housing has a connection opening and a front end opening. The push rod assembly is movably connected to the housing along a first direction, and at least a portion of the push rod assembly extends out of the housing from the front end opening. The push rod assembly includes a first seat, and the first seat has a first switching groove. The puncture needle assembly is movably connected to the housing along the first direction, and at least a portion of the puncture needle assembly extends out of the housing from the front end opening. The puncture needle assembly includes a third seat, and the third seat has a second switching groove. The second switching groove and the first switching groove are spaced apart along a second direction, and the second direction intersects the first direction. The switching member is detachably connected to the housing. The switching member includes a handle, a connecting shaft, and a cam shaft. The connecting shaft connects the handle and the cam shaft. When the switching member is configured to extend into the housing from the connection opening, at least a portion of the connecting shaft and the cam shaft are accommodated in the first and second switching grooves. At this time, rotating the switching member along the axis of the connecting shaft causes the cam shaft to rotate within the first and second switching grooves, driving the first and third seats to move along the first direction. By providing a first switching groove on the first seat and a second switching groove on the third seat, when the switching element rotates, the convex shaft rotates within the first and second switching grooves, driving the first and third seats to move along a first direction. This changes the extension length of the puncture needle assembly and the push rod assembly extending beyond their front openings, allowing the implantation device to meet different surgical requirements. Furthermore, by providing the switching element, when the switching element is not pulled out of the connection opening, the convex shaft restricts the movement of the push rod assembly and the puncture needle assembly along the first direction by limiting the movement of the first and second switching grooves, thus preventing accidental activation of the implantation device.

[0040] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0041] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0042] The applicant found that in the existing technology, the two surgical procedures for implanting aqueous humor drainage tubes have different puncture depths, and usually require two implantation systems to deal with different situations.

[0043] In view of the above problems, the applicant proposes an implantation device for implanting an implant. The implantation device includes a housing, a push rod assembly, a puncture needle assembly, and a switching element. The housing has a connection opening and a front end opening. The push rod assembly is movably connected to the housing along a first direction, and at least a portion of the push rod assembly extends out of the housing from the front end opening. The push rod assembly includes a first seat, and the first seat has a first switching groove. The puncture needle assembly is movably connected to the housing along the first direction, and at least a portion of the puncture needle assembly extends out of the housing from the front end opening. The puncture needle assembly includes a third seat, and the third seat has a second switching groove. The second switching groove and the first switching groove are spaced apart along a second direction, and the second direction intersects the first direction. The switching element is detachably connected to the housing. The switching element includes a handle, a connecting shaft, and a cam shaft. The connecting shaft connects the handle and the cam shaft. When the switching element is configured to extend into the housing from the connection opening, at least a portion of the connecting shaft and the cam shaft are accommodated in the first and second switching grooves. At this time, rotating the switching element along the axis of the connecting shaft causes the cam shaft to rotate within the first and second switching grooves, driving the first and third seats to move along the first direction.

[0044] The implantation device provided in this application, by providing a first switching groove on a first base and a second switching groove on a second base, allows the convex shaft to rotate within the first and second switching grooves when the switching element rotates, driving the first and third bases to move along a first direction. This changes the extension length of the portions of the puncture needle assembly and the push rod assembly extending beyond their front openings, enabling the implantation device to meet different surgical requirements. By providing the switching element, when the switching element is not pulled out of the connection opening, the convex shaft restricts the movement of the first and second switching grooves along the first direction, thereby limiting the travel of the push rod assembly and the puncture needle assembly in the first direction and preventing accidental activation of the implantation device.

[0045] The display module provided in the embodiments of this application will be described below with reference to the accompanying drawings. It should be noted that the x-direction in the drawings is the first direction, the y-direction is the second direction, and the z-direction is the third direction. In the drawings, for ease of drawing, the dimensions are not necessarily proportional to the actual dimensions. To ensure clarity, some outlines may be hidden in the drawings, and line widths may be differentiated.

[0046] Please refer to Figures 1 to 3 , Figure 1 This is a three-dimensional structural diagram of an implantation device according to some embodiments of this application; Figure 2 An example is shown. Figure 1 A schematic diagram of the exploded structure of the implanted device and implant;

[0047] Figure 3 An example is shown. Figure 1 An exploded view of the push rod assembly, puncture needle assembly, and switching component.

[0048] like Figures 1 to 3 As shown, this application provides an implantation device 100 for implanting an implant 200. The implantation device 100 includes a housing 10, a push rod assembly 20, a puncture needle assembly 30, and a switching element 40. The housing 10 has a connection opening 11 and a front end opening 12. The push rod assembly 20 is movably connected to the housing 10 along a first direction (x direction in the figure). At least a portion of the push rod assembly 20 extends out of the housing 10 from the front end opening 12. The push rod assembly 20 includes a first seat 21, on which a first switching groove 211 is provided. The puncture needle assembly 30 is movably connected to the housing 10 along the first direction x. At least a portion of the puncture needle assembly 30 extends out of the housing 10 from the front end opening 12. The puncture needle assembly 30 includes a third seat 31, on which a second switching groove 311 is provided. The second switching groove 311 and the first switching groove 211 are spaced apart along a second direction (y direction in the figure), and the second direction y intersects the first direction x. The switching element 40 is detachably connected to the housing 10. The switching element 40 includes a handle 41, a connecting shaft 42, and a cam 43. The connecting shaft 42 connects the handle 41 and the cam 43. When the switching element 40 is extended into the housing 10 from the connection opening 11, at least part of the connecting shaft 42 and the cam 43 are accommodated in the first switching groove 211 and the second switching groove 311. At this time, the switching element 40 is rotated along the axis of the connecting shaft 42, and the cam 43 rotates in the first switching groove 211 and the second switching groove 311, driving the first seat 21 and the third seat 31 to move along the first direction x.

[0049] Optionally, the implant 200 can be a conventional implant or an expansion stent. The expansion stent is made of shape memory materials, including nickel-titanium alloys, indium-thallium alloys, etc.

[0050] Optionally, during the procedure, the implant 200 is inserted into the patient's trabecular meshwork via the implantation device 100. After implantation into the patient's trabecular meshwork, the implant 200 becomes a pathway connecting the patient's anterior chamber to the Schlemm's canal, allowing aqueous humor to flow out of the anterior chamber through the implant 200, thereby reducing the patient's intraocular pressure and slowing the progression of glaucoma.

[0051] Optionally, in different embodiments, the implant 200 can be used to transfer aqueous humor to different parts of the eye, such as the space between the conjunctiva and sclera, the suprachoroidal space, a Schlemm tube, or a fluid reservoir formed on the posterior surface of the eye.

[0052] Optionally, after the switching member 40 extends into the connecting opening 11, depending on the rotation direction of the switching member 40, the convex shaft 43 can drive the first seat 21 to move relative to the second seat 22 in a direction away from the front opening 12, and drive the third seat 31 to move relative to the fourth seat 32 in a direction away from the front opening 12. This results in a shorter extension length of the push rod assembly 20 and the puncture needle assembly 30 extending beyond the front opening 12, making the implantation device 100 suitable for external implantation procedures. Alternatively, the convex shaft 43 can drive the first seat 21 to move relative to the second seat 22 in a direction towards the front opening 12, and drive the third seat 31 to move relative to the fourth seat 32 in a direction towards the front opening 12, resulting in a longer extension length of the push rod assembly 20 and the puncture needle assembly 30 extending beyond the front opening 12, making the implantation device 100 suitable for internal implantation procedures.

[0053] Optionally, the switching element 40 is key-shaped and can extend into the housing 10 through the connection opening 11. When the switching element 40 is inserted into the housing 10, the implantation device 100 cannot implant the implant 200 due to the limiting effect of the connecting shaft 42, the convex shaft 43, the first switching groove 211, and the second switching groove 311. After the switching element 40 rotates and completes the internal and external switching of the implantation device 100, the switching element 40 needs to be pulled out from the connection opening 11 before the implantation device 100 can perform the implantation operation.

[0054] Optionally, the push rod assembly 20 further includes a second seat 22, with the first seat 21 and the second seat 22 movably connected along a first direction x, and the second seat 22 located on the side of the first seat 21 opposite to the front opening 12. The puncture needle assembly 30 further includes a fourth seat 32, with the third seat 31 movably connected to the fourth seat 32 along the first direction x, and the fourth seat 32 located on the side of the third seat 31 opposite to the front opening 12. The switching member 40 is configured such that when the convex shaft 43 rotates within the first switching groove 211 and the second switching groove 311, it drives the first seat 21 to move relative to the second seat 22 along the first direction x, and drives the third seat 31 to move relative to the fourth seat 32 along the first direction x.

[0055] The implantation device 100 provided in this embodiment movably connects the first seat 21 and the second seat 22 along the first direction x, and the third seat 31 and the fourth seat 32 along the first direction x. A first switching groove 211 is provided on the first seat 21, and a second switching groove 311 is provided on the third seat 31. When the switching member 40 rotates, the convex shaft 43 rotates within the first and second switching grooves 211 and drives the first seat 21 and the third seat 31 to move along the first direction x. This changes the extension length of the portion of the puncture needle assembly 30 and the push rod assembly 20 extending out of the front opening 12, allowing the implantation device 100 to meet different surgical requirements. By providing the switching member 40, when the switching member 40 is not pulled out of the connection opening 11, the convex shaft 43 restricts the movement of the first and second switching grooves 211 along the first direction x, thereby limiting the travel of the push rod assembly 20 and the puncture needle assembly 30 in the first direction x, preventing accidental activation of the implantation device 100.

[0056] In some optional embodiments, the puncture needle assembly 30 further includes a puncture needle 33 connected to a third seat 31, located on the side of the third seat 31 opposite to the fourth seat 32, with at least a portion of the puncture needle 33 extending out of the housing 10 from the front opening 12, and a receiving cavity (not shown) provided within the puncture needle 33 for receiving the implant 200. The push rod assembly 20 further includes a push rod 23 connected to a first seat 21, located on the side of the first seat 21 opposite to the second seat 22, with at least a portion of the push rod 23 extending out of the housing 10 from the front opening 12, and at least a portion of the push rod 23 located within the receiving cavity.

[0057] Optionally, the implantation device 100 further includes a limiting tube 50, which is connected to the housing 10. At least a portion of the limiting tube 50 is sleeved over the puncture needle 33. The puncture needle 33, the push rod 23, and the limiting tube 50 all extend along a first direction x. When the implantation device 100 is in use, the puncture needle 33 is inserted into the patient's tissue, and the limiting tube 50 is placed against the tissue surface. The length of the puncture needle 33 extending from the limiting tube 50 is the puncture depth.

[0058] Please refer to Figure 4 and Figure 5 , Figure 4 An example is shown. Figure 3 A cross-sectional view of the push rod assembly after the push rod is hidden. Figure 5 An example is shown. Figure 3 A cross-sectional view of the puncture needle assembly after the puncture needle is concealed.

[0059] like Figure 4 and Figure 5As shown, in some optional embodiments, the push rod assembly 20 further includes a first limiting block. The first limiting member includes a first locking tooth 24 and a first locking groove 25, which are respectively located on the first seat 21 and the second seat 22. At least two first locking grooves 25 are spaced apart along a first direction x. The puncture needle assembly 30 includes a second limiting member, which includes a second locking tooth 34 and a second locking groove 35, which are respectively located on the third seat 31 and the fourth seat 32. At least two second locking grooves 35 are spaced apart along a first direction x.

[0060] Optionally, the first seat 21 has two first slots 25 on the side facing the second seat 22, and the second seat 22 has a protruding first tooth 24 on the side facing the first seat 21. The size of the first tooth 24 matches that of the first slots 25. When the switching member 40 rotates within the housing 10, the convex shaft 43 drives the first seat 21 to move relative to the second seat 22 along the first direction x, and the first tooth 24 moves from one of the first slots 25 to the other. The positions of the first slots 25 and the first tooth 24 can also be reversed.

[0061] Optionally, there is friction between the first locking tooth 24 and the first locking groove 25. This friction causes the first seat 21 and the second seat 22 to move synchronously when the switching element 40 is not inserted into the housing 10. The friction should be greater than the resistance when the puncture needle 33 pierces the tissue and the resistance when the push rod 23 pushes the implant 200. When it is necessary to switch the surgical mode, in addition to inserting the switching element into the housing 10 and rotating it, it is also necessary to restrict the movement of the second seat 22 along the first direction x. At this time, the cam shaft 43 drives the first seat 21 to overcome the friction between the first locking groove 25 and the first locking tooth 24, and causes the first seat 21 to move relative to the second seat 22.

[0062] The second limiting member operates on the same principle as the first limiting member, and will not be described again here.

[0063] The implantation device 100 provided in this embodiment provides a first limiting member between the first seat 21 and the second seat 22, and a second limiting member between the third seat 31 and the fourth seat 32, so that the first seat 21 and the third seat 31 have two positions relative to the second seat 22 and the fourth seat 32, i.e. two surgical modes, and these two modes will not switch with each other when the switching member 40 is not inserted into the housing 10, thereby improving the precision of the surgery.

[0064] In some optional embodiments, the first switching slot 211 includes a first straight segment 212, a second straight segment 213, and a first connecting segment 214. The first straight segment 212 extends along a first direction x, the second straight segment 213 extends along a third direction (z direction in the figure), and the first connecting segment 214 connects the first straight segment 212 and the second straight segment 213. The second switching slot 311 includes a third straight segment 312, a fourth straight segment 313, and a second connecting segment 314. The third straight segment 312 extends along the first direction x, the fourth straight segment 313 extends along a third direction z, and the second connecting segment 314 connects the third straight segment 312 and the fourth straight segment 313. The third direction z, the first direction x, and the second direction y intersect each other.

[0065] Optionally, the first direction x is defined as the front-back direction of the implantation device 100, the second direction y is defined as the up-down direction of the implantation device 100, and the third direction z is defined as the left-right direction of the implantation device 100.

[0066] Optionally, both the first switching slot 211 and the second switching slot 311 are L-shaped.

[0067] Please refer to Figures 4 to 6 , Figure 6 An example is shown. Figure 3 A three-dimensional structural diagram of the switching component.

[0068] like Figures 4 to 6 As shown, in some optional embodiments, the convex shaft 43 includes a first convex shaft 431 and a second convex shaft 432. When the switching member 40 is configured to extend into the housing 10 from the connection opening 11, at least a portion of the connecting shaft 42 is accommodated in the first connecting segment 214 and the second connecting segment 314, at least a portion of the first convex shaft 431 is accommodated in the second straight segment 213, and at least a portion of the second convex shaft 432 is accommodated in the fourth straight segment 313.

[0069] Optionally, when the switching member 40 rotates along the axis of the connecting shaft 42, the first cam 431 and the second cam 432 swing in a fan shape. The first cam 431 presses against the side wall of the second straight segment 213, and the second cam 432 presses against the side wall of the fourth straight segment 313. When the position of the second seat 22 is fixed, and the thrust of the first cam 431 on the second straight segment 213 is greater than the friction between the first locking tooth 24 and the first locking groove 25, the first cam 431 drives the first seat 21 to move relative to the second seat 22 in the first direction x toward the direction away from the front opening 12, and the length of the push rod 23 extending out of the front opening 12 becomes shorter. Similarly, the second cam 432 drives the third seat 31 to move in the first direction x toward the direction away from the front opening 12. When the switching component 40 rotates 90 degrees, the first convex shaft 431 is located in the first straight segment 212, the connecting shaft 42 is located at one end of the first straight segment 212 away from the first connecting segment 214, the second convex shaft 432 is located in the third straight segment 312, and the connecting shaft 42 is located at one end of the third straight segment 312 away from the second connecting segment 314.

[0070] In some alternative embodiments, when the switching member 40 extends into the housing 10, the first convex shaft 431 is located in the first straight segment 212, the connecting shaft 42 is located at one end of the first straight segment 212 away from the first connecting segment 214, the second convex shaft 432 is located in the third straight segment 312, and the connecting shaft 42 is located at one end of the third straight segment 312 away from the second connecting segment 314. Rotating the switching member 40 90 degrees in the opposite direction causes the first convex shaft 431 and the second convex shaft 432 to drive the first seat 21 and the third seat 31 to move along the first direction x toward the front opening 12, and the push rod 23 and the puncture needle 33 extend beyond the length of the front opening 12. At this time, the connecting shaft 42 is accommodated in the first connecting segment 214 and the second connecting segment 314, the first convex shaft 431 is accommodated in the second straight segment 213, and the second convex shaft 432 is accommodated in the fourth straight segment 313.

[0071] In some optional embodiments, the first limiting member includes three first slots 25, which are spaced apart along a first direction x. In the initial position, the first locking tooth 24 is located in the middle first slot 25. The user can rotate the switching member 40 clockwise or counterclockwise to drive the first seat 21 and the third seat 31 toward or away from the front opening 12, thereby shortening or lengthening the puncture needle 33 and the push rod 23. The second limiting member can be configured with reference to the first limiting member.

[0072] In some alternative embodiments, the distance from the end of the first convex shaft 431 away from the connecting shaft 42 to the connecting shaft 42 is not equal to the distance from the end of the second convex shaft 432 away from the connecting shaft 42 to the connecting shaft 42.

[0073] The implantation device 100 provided in this embodiment, by making the lengths of the first convex shaft 431 and the second convex shaft 432 unequal, and the stroke of the push rod 23 and the stroke of the puncture needle 33 unequal when the switching member 40 rotates, thereby meeting the different stroke requirements of the push rod 23 and the puncture needle 33 between two surgical procedures and expanding the applicable scenarios of the implantation device 100.

[0074] In some alternative embodiments, the width of the first convex shaft 431 is smaller than the width of the first straight line segment 212 and the second straight line segment 213, and the width of the second convex shaft 432 is smaller than the width of the third straight line segment 312 and the fourth straight line segment 313.

[0075] The implantation device 100 provided in this embodiment allows the first convex shaft 431 to swing within the first and second straight segments 212 and 213 by making the width of the first convex shaft 431 smaller than the width of the first straight segment 212 and the second straight segment 213, thereby driving the first seat 21 to move along the first direction x. Similarly, by making the width of the second convex shaft 432 smaller than the width of the third and fourth straight segments 312 and 313, the second convex shaft 432 can swing within the third and fourth straight segments 312 and 313, thereby driving the third seat 31 to move along the first direction x.

[0076] Please continue to refer to this. Figure 2 In some optional embodiments, the connecting opening 11 includes a fifth straight segment 111, a sixth straight segment 112 and a third connecting segment 113, the fifth straight segment 111 extending along a first direction x, the sixth straight segment 112 extending along a third direction z, and the third connecting segment 113 connecting the fifth straight segment 111 and the sixth straight segment 112.

[0077] Optionally, the connecting opening 11 is L-shaped. When the switching member 40 is used to shorten the puncture needle 33 and the push rod 23, the convex shaft 43 extends into the housing 10 from the sixth straight segment 112 and exits the housing 10 from the fifth straight segment 111 after rotating 90 degrees, wherein the connecting shaft 42 is always located in the third connecting segment 113. When the switching member 40 is used to extend the puncture needle 33 and the push rod 23, the convex shaft 43 extends into the housing 10 from the fifth straight segment 111 and exits the housing 10 from the sixth straight segment 112 after rotating 90 degrees in the opposite direction, wherein the connecting shaft 42 is always located in the third connecting segment 113.

[0078] Please refer to Figure 2 , Figure 7 and Figure 8 , Figure 7 An example is shown. Figure 2 An exploded view of the push rod assembly, puncture needle assembly, and rotary wheel; Figure 8 An example is shown. Figure 2 The push rod assembly, puncture needle assembly, and rotary wheel are shown in an exploded structural diagram from another perspective.

[0079] like Figure 2 , Figure 7 and Figure 8 As shown, in some optional embodiments, the implantation device 100 further includes a rotating wheel 60, which is connected to the housing 10 via a rotating shaft 61. A second seat 22 and a fourth seat 32 are respectively connected to the two end faces of the rotating wheel 60. As the rotating wheel 60 rotates, it can drive the push rod assembly 20 to move in a first direction x away from the rotating wheel 60, and drive the puncture needle assembly 30 to move in the first direction x towards the rotating wheel 60. The housing 10 has a central opening 13, and at least a portion of the rotating wheel 60 extends out of the housing 10 from the central opening 13.

[0080] The implantation device 100 provided in this embodiment allows the user to fix the positions of the second seat 22 and the fourth seat 32 by manually restricting the rotation of the rotating wheel 60 when using the switching component 40. Then, rotating the switching component 40 extends or retracts the puncture needle 33 and the push rod 23. During implantation, rotating the rotating wheel 60 causes the push rod assembly 20 to move in the first direction x away from the rotating wheel 60. The push rod 23 pushes the implant 200 forward, and the rotating wheel 60 causes the puncture needle assembly 30 to move in the first direction x towards the rotating wheel 60. The puncture needle 33 retracts, exposing the implant 200, completing the implantation operation.

[0081] In some optional embodiments, the two end faces of the rotating wheel 60 are respectively provided with a first groove 62 and an eccentric first connecting rod shaft 63. The end of the second seat 22 opposite to the first seat 21 is provided with a second connecting rod shaft 221 corresponding to the first groove 62, and the end of the fourth seat 32 opposite to the third seat 31 is provided with a second groove 321 corresponding to the first connecting rod shaft 63. The first groove 62 includes a first variable radius groove section 621 and a first arc-shaped groove section 622. When the rotating wheel 60 rotates, the second connecting rod shaft 221 slides from the end of the first variable radius groove section 621 to the end of the first arc-shaped groove section 622, thereby driving the push rod assembly 20 to move in the first direction x in the direction opposite to the rotating wheel 60. The second groove 321 includes a second arc-shaped groove section 323 and a second variable radius groove section 322. When the rotating wheel 60 rotates, the first connecting rod shaft 63 slides from the end of the second arc-shaped groove section 323 to the end of the second variable radius groove section 322, thereby driving the puncture needle assembly 30 to move along the first direction x toward the rotating wheel 60.

[0082] Optionally, the center of the first arc-shaped groove segment 622 coincides with the center of the rotating wheel 60. The first arc-shaped groove segment 622 is connected to the first variable radius groove segment 621. The first variable radius groove segment 621 can be a groove segment of various shapes, such as an involute groove segment. When the rotating wheel 60 rotates, the second connecting rod shaft 221 slides from the end of the first variable radius groove segment 621 toward the end of the first arc-shaped groove segment 622. In the first variable radius groove segment 621, the distance between the second connecting rod shaft 221 and the rotating shaft 61 gradually increases, and then enters the first arc-shaped groove segment 622. After that, the distance between the second connecting rod shaft 221 and the rotating shaft 61 remains unchanged.

[0083] Optionally, the second variable radius groove segment 322 and the second arc-shaped groove segment 323 are connected. The second variable radius groove segment 322 can be selected from various shapes of groove segments, such as an arc-shaped groove with an approximate involute shape. When the wheel 60 rotates, the first connecting rod shaft 63 on the wheel 60 slides from the end of the second arc-shaped groove segment 323 toward the end of the second variable radius groove segment 322. In the second arc-shaped groove segment 323, the distance between the first connecting rod shaft 63 and the center of the second arc-shaped groove segment 323 remains constant. Then, as it enters the second variable radius groove segment 322, the distance between the first connecting rod shaft 63 and the center of the second arc-shaped groove segment 323 gradually decreases.

[0084] Optionally, in the initial state, the second connecting rod shaft 221 is located at the end of the first variable radius groove segment 621 of the first groove 62, and the first connecting rod shaft 63 is located at the end of the second arc-shaped groove segment 323 in the second groove 321. After the rotating wheel 60 rotates, the first groove 62 first drives the push rod assembly 20 to move away from the rotating wheel 60 along the first direction x, and the push rod 23 pushes the implant 200 forward. Then, the first connecting rod shaft 63 drives the puncture needle assembly 30 to move towards the rotating wheel 60 along the first direction x, and the puncture needle 33 retracts and exposes the implant 200 to complete the implantation operation.

[0085] Please refer to Figure 9 and Figure 10 , Figure 9 A top view of an example third-base structure is shown; Figure 10 Another example is shown Figure 2 A partially enlarged structural diagram of the push rod assembly, puncture needle assembly, and rotary wheel. Among them, Figure 10 For ease of description, some parts in the attached drawings are shown in cross-section.

[0086] like Figure 9 and Figure 10As shown, in some alternative embodiments, the push rod assembly 20 does not include the second seat 22, and the puncture needle assembly 30 does not include the fourth seat 32. The first seat 21 and the third seat 31 are respectively connected to the two end faces of the rotating wheel 60, and as the rotating wheel 60 rotates, they can drive the push rod assembly 20 to move away from the rotating wheel 60 in the first direction x, and drive the puncture needle assembly 30 to move towards the rotating wheel 60 in the first direction x.

[0087] Optionally, the two end faces of the rotating wheel 60 are respectively provided with a first groove and a second groove. The end of the first seat 21 opposite to the front opening 12 is provided with a third groove 26 and a third connecting shaft 27 corresponding to the first groove. One end of the third connecting shaft 27 extends into the first groove, and the other end is movably connected to the third groove 26 along the first direction x. The end of the third seat 31 opposite to the front opening 12 is provided with a fourth groove (not shown) and a fourth connecting shaft (not shown) corresponding to the second groove. One end of the fourth connecting shaft extends into the second groove, and the other end is movably connected to the fourth groove along the first direction x. Both the third groove 26 and the fourth groove are provided with at least two locking positions 261 spaced apart along the first direction x. When the switching component 40 is configured to rotate within the first switching groove 211 and the second switching groove 311, the convex shaft 43 drives the first seat 21 and the third seat 31 to move along the first direction x until the third connecting rod shaft 27 moves from one of the engagement positions 261 of the third groove 26 to the other engagement position 261, and the second connecting rod shaft moves from one of the engagement positions of the fourth groove to the other engagement position.

[0088] Optionally, the first and second grooves can be configured as described in the above embodiments. The third groove 26 and the fourth groove extend along the first direction x. There is friction between the third connecting rod shaft 27 and the third groove 26, and between the fourth connecting rod shaft and the fourth groove. This friction prevents the connecting rod shaft from sliding in the third groove 26 and the fourth groove when the switching member 40 is not inserted into the housing 10. The friction should be greater than the resistance when the puncture needle 33 pierces the tissue and the resistance when the push rod 23 pushes the implant 200. When it is necessary to switch the surgical mode, the convex shaft 43 drives the first seat 21 and the third seat 31 to overcome the friction between the connecting rod shaft and the third groove 26 and the fourth groove, and moves the connecting rod shaft from one of the locking positions 261 to the other locking position 261.

[0091] Step S01: Insert the switching component 40 into the housing 10 from the connection opening 11, with at least part of the connecting shaft 42 and the convex shaft 43 accommodated in the first switching groove 211 and the second switching groove 311.

[0092] Step S02: Rotate the switching component along the axis of the connecting shaft 42, and rotate the convex shaft 43 within the first switching groove 211 and the second switching groove 311.

[0093] Step S03: The convex shaft 43 drives the first seat 21 to move along the first direction x, and the convex shaft 43 drives the third seat 31 to move along the first direction x.

[0095] Step S05: Insert the implantation system into the patient's eye.

[0096] In step S06, the rotating wheel 60 is rotated. The first groove 62 first drives the push rod assembly 20 to move away from the rotating wheel 60 along the first direction x. The push rod 23 pushes the implant 200 forward. Then the first connecting rod shaft 63 drives the puncture needle assembly 30 to move along the first direction x towards the rotating wheel 60. The puncture needle 33 retracts and exposes the implant 200 to complete the implantation operation.
