Description

Technical Field

[0001] The present invention relates to the field of intelligent medicine, and more specifically, to an implantor for refractive correction, an implantation method, a system and a device based on the implantor. Background Art

[0002] Corneal stromal lenticule implantation is a newly emerging surgical procedure in recent years. Briefly, the process is to implant the discarded corneal stromal lenticule removed during SMILE surgery from a healthy donor into the eyes of recipient patients with thin corneas or those who have higher requirements for corneal thickness in further surgical treatments. The conventional implantation process is to first create a conventional pocket in the recipient eye using SMILE surgery, then use forceps to insert and flatten the corneal stromal sheet and lenticule into the pocket, and then perform a water-tight incision.

[0003] Existing problems: Since the edge incision of the pocket made by SMILE surgery is only 2 - 4 μm, although the corneal stromal lenticule has good ductility and flexibility, it is still very difficult to simply insert it into the pocket through the incision using forceps, and after insertion, it is mostly in a curled state, and occasionally there is a situation of the folded surface. Moreover, the pocket space is very small, and surgical operations in it will inevitably cause abrasion and other effects on the patient's anterior elastic layer and stromal layer, often resulting in postoperative corneal haze and edema, relative displacement of the implant, etc., which requires high experience and skills for the surgeon. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides an implantor for refractive correction, an implantation method, a system and a device based on the implantor.

[0010] In some embodiments, the through holes are provided on the left side and / or the right side of the placement sheet.

[0011] The second aspect of the present application discloses an implantation method based on the implantor described in the first aspect of the present application, and the method includes:

[0012] S101, making a capsular bag and making an incision of 4 - 5 μm in the capsular bag;

[0013] S102, placing the graft on the placement sheet described in the first aspect of the present application, and folding the placement sheet with the side on which the graft is placed as the inner side; at least one edge of the graft is exposed outside the edge of the folded placement sheet;

[0014] S103, putting the folded placement sheet into the capsular bag from the incision;

[0016] S105, rotating the placement sheet, and the graft flattens inside the capsular bag to complete the implantation.

[0017] In some embodiments, the manner in which at least one edge of the graft is exposed outside the edge of the folded placement sheet includes: the graft exposes the edge through the through hole, or the graft exposes the edge through the misalignment region formed after folding of the first region and the second region;

[0018] Optionally, the instrument in S104 is a fixation forceps;

[0019] Optionally, the graft is a lens.

[0020] The third aspect of the present application discloses an implantation system based on the implantor described in the first aspect of the present application, and the system includes:

[0021] A capsular bag making module 201, configured to make a capsular bag and make an incision of 4 - 5 μm in the capsular bag;

[0022] A graft placement module 202, which is used for or configured to place a graft on the placement sheet described in the first aspect of the present application, and fold the placement sheet with the side having the graft placed thereon as the inner side; at least one edge of the graft is exposed outside the edge of the folded placement sheet;

[0029] The present application has the following beneficial effects: 1. The present application innovatively discloses an implant for refractive correction. This implant completely abandons the traditional operation of using forceps to clamp the graft and unfold and flatten it inside the lens. Instead, it directly adopts a more gentle operation of placing the graft into the implant, folding the placement sheet and implanting the placement sheet into the pocket, and then using the pre-set misaligned area or through holes on the placement sheet to clamp the graft exposed at the edge of the placement sheet by a fixation forceps, and realizing the operation of flattening the graft by directly rotating the implant in a fan shape. This not only effectively avoids the problem that in the prior art, when the graft is stuffed into the pocket by forceps, most of the grafts are in a curled state or there are folded surfaces, which may cause abrasion or other adverse effects on the anterior elastic layer and stromal layer during the operation in a pocket with a small space, but also effectively solves the problem of damage to the graft caused by violent clamping of the graft, protecting the corneal tissue.

[0030] 2. The present application innovatively discloses an implantation method using an implant, which can complete the surgical operation in a relatively short time and has relatively low requirements for the experience and skills of the operator. Description of the Drawings

[0041] To enable those skilled in the art to better understand the solutions of the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention.

[0042] In some processes described in the specification, claims and above-mentioned drawings of the present invention, a plurality of operations appear in a specific order. However, it should be clearly understood that these operations may not be executed in the order in which they appear herein or may be executed in parallel. The serial numbers of the operations, such as 101, 102, etc., are only used to distinguish different operations, and the serial numbers themselves do not represent any execution order. In addition, these processes may include more or fewer operations, and these operations may be executed in sequence or in parallel. It should be noted that the descriptions such as "first" and "second" in this article are used to distinguish different messages, devices, modules, etc., and do not represent a sequence, nor do they limit that "first" and "second" are of different types.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0044] The embodiments of the present invention specifically disclose an implant for refractive correction. The implant includes an implantation sheet 1; the implantation sheet 1 includes a first region 11 and a second region 12, and a folding line is provided between the first region 11 and the second region 12; the first region 11 and the second region 12 are folded along the folding line, and the graft is placed inside the fold; after folding, the implantation sheet 1 has a space for the graft to extend out of the edge, so that at least one edge of the graft is exposed outside the edge of the implantation sheet 1 through the space.

[0045] In some embodiments, as Figure 6 shown, the space includes through holes 14 provided in the first region 11 and / or the second region 12. The size, shape and position of the through holes 14 are configured to allow the lens 2 to extend out of at least one edge through the through holes 14; optionally, the first region 11 and the second region 12 are symmetric in shape, and the first region 11 and the second region 12 completely overlap and fold after folding.

[0046] In some embodiments, the through holes 14 are provided on the left side and / or the right side of the implantation sheet 1. As Figure 6The through hole 14 shown is provided on the left side of the implantation sheet 1. It should be noted that the positions of the through hole 14 or the misalignment area 13 are set according to the habits of the operator. For example, for an operator who habitually operates with the right hand, the through hole 14 or the misalignment area 13 is set at a position slightly to the left of the implantation sheet 1. Holding the fixation forceps with the left hand and using the right hand to perform translational and fan-shaped unfolding and rotation is more in line with the operating habits. If it is an operator who habitually operates with the left hand, the through hole 14 or the misalignment area 13 is set at a position slightly to the right of the implantation sheet 1. Holding the fixation forceps with the right hand and using the left hand to perform translational and fan-shaped unfolding and rotation is more in line with the operating habits. Since the lens 2 itself is part of the corneal stroma layer, it has good toughness and certain self-recovery ductility. After being rolled up, it has an outward elastic deformation. The thickness of the lens 2 varies from 50 to 100 μm. Since it is not completely inserted into the capsular bag, that is, the edge is left outside, the process of flattening the lens 2 by clamping the edge with the fixation forceps can be achieved through the through hole 14 or the misalignment area 13.

[0047] In some embodiments, the space includes a misalignment area 13 formed between the first area 11 and the second area 12 after folding. At this time, the shapes of the first area 11 and the second area 12 are asymmetric, and the shape of the asymmetric area is non-mirror symmetric; the size and shape of the misalignment area 13 are configured to allow the lens 2 to be located in the misalignment area 13 or extend out of at least one edge of the misalignment area 13; as Figure 7 shown, it is a schematic diagram of the misalignment area 13 formed after folding the first area 11 and the second area 12, with the edge of the lens 2 located in the misalignment area 13. The outside of the edge of the implantation sheet 1 is the edge of the smaller-sized area; or extend out of at least one edge of the misalignment area 13, as Figure 8 shown, it is a schematic diagram of the misalignment area 13 formed after folding the first area 11 and the second area 12, with the edge of the lens 2 extending out of the misalignment area 13. At this time, the outside of the edge of the implantation sheet 1 is the edge of the larger-sized area.

[0048] In some more specific embodiments, the space includes a through hole 14 provided in the misalignment area 13 and / or the first area 11 and / or the second area 12. The size, shape, and position of the through hole 14 are configured to allow the lens 2 to extend out of at least one edge through the through hole 14.

[0049] In some more specific embodiments, the implantation sheet 1 is made of an elastic and foldable material, and the material includes: silicone rubber, thermoplastic polyurethane, polyimide, nitrile rubber.

[0050] Of course, in some examples, the selectable materials are diverse and cannot be exhaustively listed in this application.

[0051] In some embodiments, the implantor further includes a handle 3 connected to the implanting sheet 1. The handle 3 includes a connected section and an operating section. The connected section is connected to the implanting sheet 1, and the outer surface of the connected section is smooth. The operating section is convenient for the operator to hold by hand, and its specific shape and length are not limited. The operating section of the handle 3 can be set to a straight shape or a curved shape.

[0052] It should be noted that the specific shape of the implanting sheet is not specifically limited in this embodiment. For example, Figure 6 as shown, the implanting sheet is set in a shape that is wider at the top and narrower at the bottom; as Figure 7 and Figure 8 shown, the implanting sheet is set to be rectangular.

[0053] In some embodiments, the folding line is collinear or non - collinear with the center line of the handle 3. If the first region 11 and the second region 12 are symmetrically distributed, the folding line is collinear with the center line; if the first region 11 and the second region 12 are asymmetrically distributed, the folding line is non - collinear with the center line.

[0054] Figure 1 FIG. is a schematic flow chart of an implantation method provided in the second aspect of the embodiments of the present invention. Specifically, the method includes the following steps: S101, making a pocket and making an incision of 4 - 5 μm in the pocket;

[0055] S102, placing the graft on the implanting sheet 1 described in the first aspect of the present application, and folding the implanting sheet 1 with the side on which the graft is placed as the inner side; at least one edge of the graft is exposed outside the edge of the folded implanting sheet 1; the placement position of the graft on the implanting sheet 1 is not limited, as long as one end edge thereof extends beyond the edge of the implanting sheet 1;

[0056] S103, putting the folded implanting sheet 1 into the pocket through the incision;

[0057] S104, using an instrument to extend into the pocket through the incision and clamp the exposed edge of the graft;

[0059] In some embodiments, the manner in which at least one edge of the graft is exposed outside the edge of the folded implanting sheet 1 includes: the graft exposes the edge through the through - hole 14, or the graft exposes the edge through the dislocation region 13 formed after folding the first region 11 and the second region 12;

[0060] In some more specific embodiments, the instrument in S104 is a fixation forceps;
