Therefore, during the entire surgical process, the intraocular tissue is not directly exposed, the intraocular pressure can be maintained stable, and the occurrence of surgical complications is greatly reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a corneal transplant eye stabilization system. Background Art

[0002] The cornea is the transparent, fibrous membrane at the front of the eyeball. Damage to the cornea due to trauma or certain diseases can cause severe vision impairment and require corneal transplantation.

[0003] Corneal transplant surgery can be broadly divided into lamellar keratoplasty and penetrating (or full-thickness) keratoplasty. If the lesion is superficial, lamellar keratoplasty is used, while if the lesion is deeper, penetrating (or full-thickness) keratoplasty is required. The choice of surgical procedure varies depending on the type of lesion. Currently, penetrating keratoplasty remains the main surgical procedure for treating corneal blindness. Simply put, penetrating keratoplasty involves first using a corneal trephine to cut the cornea, then using corneal scissors to remove the diseased part of the central cornea, i.e., to prepare a graft hole. A corneal trephine of the corresponding specifications is then used to prepare a corneal graft. The corneal graft is then positioned in the corneal graft hole, and then surgical sutures are used to sew it in place, completing the transplant.

[0004] However, during the operation, after the corneal implant hole is prepared, the eyeball will be in an exposed state with an "open skylight", which will lead to excessively low intraocular pressure and direct exposure of intraocular tissues, resulting in serious intraoperative complications such as prolapse of eye contents and even explosive choroidal hemorrhage. In severe cases, it can directly lead to blindness in the patient. Summary of the Invention

[0012] In a specific embodiment, a spring is further provided in the second push cylinder, and when the second push rod moves to hook the removal pull wire, the spring is compressed or stretched.

[0033] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0034] This embodiment provides a corneal transplant eye stabilization system, comprising an elastic implant membrane. Prior to creating a corneal implant hole, the membrane is implanted into the eye, positioned in the anterior chamber (between the cornea and iris). The implant hole is then prepared. After the implant hole is created, the membrane shields the eye from exposure, allowing the implant to be placed and sutured. Once the implant is secured, the membrane is removed. This prevents direct exposure of intraocular tissue throughout the procedure, maintaining stable intraocular pressure and significantly reducing the risk of surgical complications.

[0035] Please refer to Figure 1-2 , Figure 1 This is a schematic structural diagram of the elastic implant membrane 1 of the corneal transplant eye stabilization system in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram of the moderately elastic implant membrane 1 in a folded state.

[0036] The elastic implant membrane 1 comprises an annular elastic support 11 and an elastic membrane body 12 supported on the inner side of the annular elastic support 11. The membrane body 12 is a thin film structure and can be made of materials such as medical silicone, PU (Polyurethane), PE (Polyethylene), etc., but is not limited to these materials. A fully transparent silicone membrane can be selected. Figure 1 The membrane body 12 is made of a transparent material. The annular elastic support 11 around the membrane body 12 can be made of materials such as PMMA (Polymethylmethacrylate) or nickel-titanium alloy, but is not limited to these two types, as long as it meets medical requirements and has elastic properties.

[0037] like Figure 1As shown, the diaphragm body 12 in this embodiment is circular, and the annular elastic support 11 is correspondingly circular. In its initial state, when not subject to external forces, the annular elastic support 11 is in an expanded, closed, annular shape, ensuring that the entire diaphragm body 12 maintains a flat, tight, circular shape when stationary. In other words, the annular elastic support 11 acts as a tensioning frame for the elastic diaphragm body 12. Of course, the shape of the diaphragm body 12 when stretched is not limited to a circle, and its morphology and structure are not limited. However, the primary purpose is to seal the corneal implant hole after implantation. Furthermore, the circular shape of the annular elastic support 11 facilitates its deployment.

[0038] The elastic implant membrane 1 in this embodiment needs to be able to switch between two states: unfolded and folded. In the unfolded state, it can seal the implant hole position of the cornea, and in the folded state, it is convenient to enter the cornea through the corneal incision (such as a minimally invasive incision) and leave the cornea from the incision. The folding here mainly refers to the unfolded state of the elastic implant membrane 1. When folded, it is flattened in the radial direction, such as Figure 2 shown.

[0039] Specifically, in order to facilitate folding in this embodiment, Figure 1 In the figure, the annular elastic bracket 11 is also provided with three elastic folding joints 111 arranged along the circumferential direction. The elastic folding joints 111 are specifically a spring-type structure. The annular elastic bracket 11 can be formed by bending a rod-like structure. By twisting the position of the elastic folding joint 111 for more than one circle, a spring-type structure can be formed. That is, the working principle of the torsion spring is utilized to allow the annular elastic bracket 11 to be deformed at the position of the elastic folding joint 111 when subjected to external force, and at the same time, it can automatically return to its initial state after the external force is removed. In addition, the provision of the elastic folding joint 111 can buffer the force applied to the annular elastic bracket 11 after folding, thereby improving the overall deformation capacity of the annular elastic bracket 11.

[0040] In addition, the annular elastic support 11 is provided with a rotating shaft-type movable joint 112. For example, the movable joint 112 is formed by riveting a rotating shaft at both ends of a rod-like structure. Other rotating shaft structures are also possible. In this case, the three elastic folding joints 111 and the one movable joint 112 divide the annular elastic support 11 into a first support segment 11a, a second support segment 11b, a third support segment 11c, and a fourth support segment 11d along the circumferential direction. The first support segment 11a and the second support segment 11b are located between two adjacent elastic folding joints 111, and the third support segment 11c and the fourth support segment 11d are located between a movable joint 112 and an elastic folding joint 111, respectively.

[0041] like Figure 1 As shown, when a force F is applied to the movable joint 112 toward the inner side of the annular elastic bracket 11, the third bracket segment 11c and the fourth bracket segment 11d rotate relative to each other and both enter the inner side of the annular elastic bracket 11, and then are in Figure 2The state shown, that is, the setting of the movable joint 112, can make the annular elastic bracket 11 partially retracted when folded, and the annular elastic bracket 11 is Figure 1 The unfolded circle folds into Figure 2 The slender shape shown in the figure achieves the purpose of reducing the overall width of the annular elastic support 11 after folding, so that it is convenient to fold the elastic implant membrane 1 and implant it into the eye through a smaller incision. Then, after the external force is removed, it can automatically unfold and seal the intraocular tissue in the eye. After the operation, it can be folded and then smoothly removed from the smaller incision.

[0042] The elastic implant membrane 1 can have different sizes, such as 7 / 8 / 9 / 10 mm, etc., to suit different sizes of eyeballs and different implant hole sizes.

[0043] In addition, if Figure 1 、 2 As shown, the annular elastic support 11 is also equipped with an implantation pull wire 14 and a removal pull wire 13, which cooperate with the implanter and remover 3 described below to facilitate the folding and removal of the elastic implant membrane 1. The two ends of the implantation pull wire 14 are respectively fixed to the movable joint 112 and the opposite elastic folding joint 111, and the two ends of the removal pull wire 13 are respectively fixed to the other two elastic folding joints 111.

[0044] Can be combined Figure 3 、 4 Understand the process of implanting and removing the elastic implant membrane 1, Figure 3 This is a schematic diagram of the elastic implant membrane 1 of the corneal transplant eye stabilization system in this embodiment being placed from the loading portion 21 of the implanter into the implant head 22; Figure 4 This is a schematic diagram of the implant pushing portion 23 of the implanter of the corneal transplant eye stabilization system in this embodiment pushing the elastic implant membrane 1 into the eye.

[0045] In this embodiment, the corneal transplant eye stabilization system includes, in addition to the elastic implant membrane 1 described above, an implanter and a remover 3 for implanting and removing the elastic implant membrane 1 .

[0046] The implanter includes a loading portion 21, an implant head 22, and an implant pusher 23. Figure 3 As shown, the loading part 21 is a flat tube structure, which includes a small diameter section 212 and a large diameter section 211. The loading inlet 21a is set in the large diameter section 211, and the outlet is set in the small diameter section 212. The radial size of the small diameter section 212 gradually decreases in the direction away from the large diameter section 211. The rear end of the implant head 22 is covered with the small diameter section 212 of the loading part 21, and the front end of the implant head 22 is provided with an outlet 22a. Figure 3Compared to the loading portion 21, the implant head 22 is thinner and also has a flat tube structure. From back to front, the diameter of the implant head 22 gradually decreases. The diameter of the implant head 22 is smallest at the outlet 22a, which can be 2-3mm. This allows the implant head 22 to be inserted into a relatively small minimally invasive incision around the cornea.

[0047] like Figure 3 As shown, the implant head 22 can be placed on the small diameter section 212 of the loading part 21, and then Figure 1 The elastic implant membrane 1 in the initial expanded state shown in the figure is loaded from the larger inlet 21a of the loading portion 21. The transverse diameter of the inlet 21a is about 11 mm to facilitate the loading of the elastic implant membrane 1. The loading portion 21 and the implant head 22 here are flat structures corresponding to the elastic implant membrane 1. Therefore, the above-mentioned radial dimension mainly refers to the transverse diameter, that is, the largest radial dimension.

[0048] After the elastic implant membrane 1 is loaded into the loading part 21, a medical hook-shaped instrument is used to extend from the outlet 22a at the front end of the implant head 22 into the implant head 22 and then into the loading part 21, and hook the implant pull wire 14, and then pull the implant pull wire 14. In order to facilitate hooking and pulling, a pull ring 15 can be provided on the pull wire 14. Of course, the implant pull wire 14 can also be hooked directly. Under the pulling action of the implant pull wire 14, the movable joint 112 drives the third bracket segment 11c and the fourth bracket segment 11d of the annular elastic bracket 11 to rotate inward and fold. At the same time, during the hooking and pulling process, the elastic implant membrane 1 moves toward the small-diameter section 212 of the loading part 21. At this time, the tube diameter of the loading part 21 is also continuously reduced, and the tube wall has an extrusion effect on the annular elastic bracket 11. After the elastic implant membrane 1 moves to the small-diameter section 212 of the loading part 21, the initial folding is completed. After further pulling, the elastic implant membrane 1 slides from the small-diameter section 212 of the loading part 21 into the implant head 22 and further folds. Figure 3 As shown, the elastic implant membrane 1 is initially located in the large diameter section 211 of the loading portion 21 and then enters the implant head 22 after being folded.

[0049] The implant pull wire 14 in this embodiment can be a double-strand wire, that is, a ring-shaped pull wire, so that after the elastic implant membrane 1 enters the implant head 22, it is convenient to cut and remove the implant pull wire 14. Of course, it can also be cut and removed if it is not a double-strand wire, which can reduce the structure entering the minimally invasive incision.

[0050] Look again Figure 4The implant pushing portion 23 includes a first push cylinder 231 and a first push rod 232, which are similar to the structure of a syringe. The first push rod 232 is inserted into the first push cylinder 121. After the elastic implant membrane 1 is placed into the implant head 22, the loading portion 21 can be separated from the implant head 22, and the rear end of the implant head 22 can be put onto the front end of the first push cylinder 121, and the outlet 22a of the implant head 22 can be inserted into the minimally invasive incision at the surgical site. Then, the first push rod 232 is pushed, and the elastic implant membrane 1 is pushed out of the implant head 22 by the first push rod 232 and passes through the minimally invasive incision into the anterior chamber of the eye to complete the implantation.

[0051] Then, a transplant hole can be prepared on the cornea and the transplant can be placed and sutured. During the operation, the elastic implant membrane 1 maintains intraocular pressure and protects intraocular tissue.

[0052] Furthermore, the elastic implant 1 can be fixed after entering the eye, making its position more stable during surgery. For example, the three elastic folding joints 111 of the annular elastic support 11 can be attached with fixing parts to ensure relative positioning of the elastic implant 1 after insertion into the eye. The fixing parts can be, for example, fixing rings. A minimally invasive incision can be made at the corresponding corneal location, and the fixing rings can be pulled outside the eye and sutured to the corneal wall before being fixed. Of course, the elastic implant 1 can also be fixed by other means, such as the fixing parts can be wedged into the annular elastic support 11 to form a horn-shaped structure.

[0053] In this embodiment, the rear end of the implant head 22 of the implant device can be enclosed by the loading portion 21 and the implant pusher 23. Obviously, the rear end of the implant head 22 can also be inserted into the loading portion 21 and the implant pusher 23. The outer cover arrangement is more conducive to the elastic implant membrane 1 entering the implant head 22 and the pushing of the first push rod 232, avoiding interference with the docking interface.

[0054] After the above-mentioned implant is sutured and fixed, the elastic implant membrane 1 needs to be taken out.

[0055] like Figure 5 、 6 As shown, Figure 5 Schematic diagram of the extractor 3 of the corneal transplant eye stabilization system in this embodiment ready to remove the elastic implant membrane 1; Figure 6 for Figure 5 Schematic diagram of the extractor 3 pulling the elastic implant membrane 1 to fold.

[0056] Figure 5The extractor 3 shown in the figure is syringe-shaped and includes a second push tube 31, a second push rod 32, a retractor rod 33, and a spring 34. The second push tube 31 includes a thin-diameter section 311 and a thick-diameter section 312, which are arranged frontally and rearwardly. The front end of the thin-diameter section 311 is flat, tubular, and can be set to an outer diameter of 2-3 mm, so that the front end of the thin-diameter section 311 can be inserted into the tiny incision in the peripheral portion of the cornea. The second push rod 32 is inserted into the second push tube 31, with the rear end of the second push rod 32 outside the second push tube 31. A spring 34 is disposed within the second push tube 31, with one end of the spring 34 located at the rear end of the second push tube 31 and the other end connected to the second push rod 32. The front end of the second push rod 32 is provided with a retractor rod 33, with the front end of the retractor rod 33 hooked.

[0057] When in use, first push the second push rod 32 to make the hook rod 33 at the front end enter the eye and hook the removal pull wire 13 of the elastic implant membrane 1. At the same time, the front end of the second push cylinder 31 extends from the minimally invasive incision around the cornea. At this time, the spring 34 is stretched. After releasing the second push rod 32, the spring 34 automatically retracts and pulls the second push rod 32 to retract. The hook rod 33 tightens the removal pull wire 13. At the same time, the auxiliary instrument (such as the phacoemulsification T-shaped hook) pushes the movable joint 112 of the annular elastic bracket 11 inward. The hook rod 33 of the extractor 3 further pulls the removal pull wire 13, which can be pulled into the second push cylinder 31. The elastic implant membrane 1 is folded, and the entire extractor 3 is pulled. The elastic implant membrane 1 can slide out from the incision, completing the removal of the elastic implant membrane 1.

[0058] It can be seen that the provision of the spring 34 here facilitates the automatic retraction of the spring 34 to drive the hook rod 33 to pull the removal wire 13. It is understandable that the connection relationship between the spring 34 and the second push rod 32 is not limited to this. For example, when the second push rod 32 is pushed to hook the removal wire 13, the spring 34 can also be compressed, as long as it can drive the second push rod 32 to return to the initial position to pull the removal wire 13. In addition, it is obviously also possible to not provide the spring 34, and the hook rod 33 can be pulled manually.

[0059] Further Figure 5 As shown, a narrow-mouthed channel 35 is provided in the second push cylinder 31. The narrow-mouthed channel 35 is mainly provided in the thin-diameter section 311. The diameter of the narrow-mouthed channel 35 is slightly larger than the radial dimension of the hook rod 33. This can better guide the hook rod 33 along its length to extend into the incision, making it easier to hook and remove the pull wire 13. Of course, the narrow-mouthed channel 35 can also be omitted.

[0060] In addition, if Figure 6 As shown, the hook rod 33 pulls the pull wire 13 and pulls it into the front end of the thin-diameter section 311, and the elastic implant membrane 1 is folded. The pull wire 13 is pulled to pull a part of the elastic implant membrane 1 into the front end of the thin-diameter section 311. Figure 6In the figure, the two elastic folding joints 111 adjacent to the movable joint 112 are folded close to each other and stuck in the front end of the thin-diameter section 311, so that the remover 3 and the elastic implant membrane 1 are relatively positioned, making it easier to remove the elastic implant membrane 1.

[0061] It should be noted that in this embodiment, both the extractor 3 and the implanter are devices with a certain hardness to achieve the implantation and removal of the elastic implant membrane 1, such as medical metal or plastic materials.

[0062] In addition, in this embodiment, a remover 3 and an inserter are specifically provided for the elastic implant membrane 1 to perform the corresponding implantation and removal operations. However, it is understood that the corneal transplant eye stabilization system can also be equipped with the aforementioned remover 3 and inserter. The elastic implant membrane 1 can be folded outside the body and then introduced into the incision using an existing hook-shaped medical device. It can also be squeezed and folded by the hook-shaped medical device before being removed. However, it is clear that the aforementioned matching inserter and remover 3 can more conveniently and safely complete the implantation and removal of the elastic implant membrane 1. The number of elastic folding joints 111 and movable joints 112 of the elastic implant membrane 1 can also be varied accordingly, and is not limited to one movable joint 112 and three elastic folding joints 111. For example, more elastic folding joints 111 can be provided. In fact, the elastic implant membrane 1 is not limited to the structure of setting the elastic folding joint 111 and the movable joint 112. The annular elastic bracket 11 and the membrane body 12 themselves can also be folded and contracted under the action of external force. The elastic folding joint 111 and the movable joint 112 make folding easier. Moreover, due to the setting of the movable joint 112, the elastic implant membrane 1 can achieve local folding and retraction, thereby reducing the length after folding and better entering from the corneal incision.

The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
