AI Technical Summary
The lack of finished suture hook products in the prior art leads to the need to make a hook manually for each operation, which increases the time and complexity of the operation, and the fixed force is insufficient, making it difficult to adapt to mass production.
A hook for fixing the lens capsule bag is designed, using an iris hook and a hollow ring to combine the sutures and fix the hollow ring, which simplifies operation and improves the fixing force.
Through this design, the hook can be mass-produced, simple to operate, strong fixed force, and is suitable for mass production and surgical use, reducing the risk of surgical time and complications.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a retractor for fixing a lens capsule bag. Background Art
[0002] The technology used for the subluxation of the lens during cataract surgery is to directly remove the entire lens and then suture an artificial lens. Alternatively, after the lens is removed by phacoemulsification or extracapsular removal, the dislocated capsular bag is retained, and a modified tension ring is used for suturing, and then the artificial lens is implanted into the capsular bag. Alternatively, after the lens is removed, the artificial lens is directly implanted into the capsular bag, and the dislocated capsular bag is hooked with a retractor made of homemade sutures, and then sutured to the scleral wall. For the dislocation of the artificial lens complex, a large incision is made directly to remove the complex, and then an artificial lens suturing operation is performed at an appropriate time. Alternatively, the artificial lens complex is sutured, but the operation is complicated and there are relatively more complications. The defects of the closest prior art are analyzed to highlight the innovative points of the present invention.
[0003] The closest existing technology is to use homemade sutures to heat the tail end of the suture into a hook-like structure, then use the hook to hook the capsular bag, and then fix the suture to the scleral wall to fix the dislocated capsular bag. However, there are currently no finished suture retractors. Each operation needs to be made manually, which has a certain failure rate, is inconvenient for mass production, and increases the operation time. The tension of the finished retractors is small, the angle is not uniform, and the fixing force for the capsular bag is weak. Some scholars also directly use iris retractors to hook the dislocated capsular bag, and then fix the long retractor directly on the scleral wall, but the shape of the retractor needs to be adjusted during the operation, and each operation cannot be standardized. The retractor on the scleral wall may be exposed in the long term, causing infection or foreign body sensation. Utility Model Content
[0004] 1. Technical Problems Solved
[0005] The technical problem to be solved by the utility model is that there is no finished suture retractor, and each operation needs to be manually made, which is inconvenient for mass production. The made retractors have low tension, non-uniform angles, and weak fixing force on the sac.
[0006] 2. Technical Solution
[0007] To solve the above technical problems, the utility model provides a technical solution: a retractor for fixing the lens capsule, comprising an iris retractor and a suture, wherein a hollow ring is provided at the rear end of the iris retractor, and one end of the suture is installed outside the hollow ring.
[0008] As an improvement, the hollow ring is perpendicular to the front end of the iris retractor.
[0009] As an improvement, the iris retractor is made of PMMA material.
[0010] As an improvement, the suture is a polypropylene non-absorbable suture.
[0011] 3. Beneficial Effects
[0012] Compared with the prior art, the utility model has the following advantages: a hollow ring is added to the rear of the iris retractor for tying sutures and fixing. The hook can be mass-produced, and the suture with a needle is directly tied to the hollow ring during surgery, which is extremely simple and convenient to operate. The retractor material has relatively stable tension and consistent angles, which has a strong fixing force on the capsular bag and is also convenient for pulling the capsular bag during surgery. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 The utility model is a structural schematic diagram of a retractor for fixing a lens capsule bag.
[0014] As shown in the figure: 1. Iris retractor; 2. Hollow ring; 3. Suture. DETAILED DESCRIPTION
[0015] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0016] As attached Figure 1 As shown, a retractor for fixing the lens capsule bag comprises an iris retractor 1 and a suture 3. The rear end of the iris retractor 1 is provided with a hollow ring 2, one end of the suture 3 is installed on the outside of the hollow ring 2, and the hollow ring 2 is perpendicular to the front end of the iris retractor 1. The iris retractor 1 is made of PMMA material, and the suture 3 is made of polypropylene non-absorbable suture.
[0017] The specific usage is as follows:
[0018] The iris retractor 1 is inserted directly from the 2 mm incision of the cataract. During the operation, the polypropylene non-absorbable suture 3 is directly fixed on the hollow ring 2. The iris retractor 1 is used to hook the dislocated lens capsule or complex. The suture 3 with a needle is straightened and directly passed through the ciliary sulcus and then fixed on the scleral wall.
[0019] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
[0020] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
