A scaled variable curvature capsular scissors

Abstract

The invention discloses a scaled variable curvature capsular scissors, which specifically includes: a front end, a connecting screw, a left piece, a right piece, a left spring piece and a right spring piece, the tail of the straight part of the front end, and the head of the left piece The head of the front part and the right piece is connected by connecting screws; it also includes adjustment screws. The head of the straight part is provided with three adjustment holes of the same size. The three adjustment holes are not on the same horizontal line. The head of the straight part and the front end The downward bending part is connected by an adjustment screw, and a fixing hole with the same size as the adjustment hole is provided at the tail of the downward bending part, and the adjustment screw fixes the straight part and the downward bending part by connecting one of the fixing hole and the adjustment hole; Scales are set on the opposite blades of the front end to realize the standardization and precision of the incision in the process of radial anterior capsulotomy, which is convenient for quantitative observation of the diameter change of the capsulorhexis area after operation, and can effectively prevent the shrinkage of the capsular bag after operation.

Description

technical field [0001] The invention relates to the field of ophthalmic surgical instruments, in particular to a scaled variable curvature capsule scissors. Background technique [0002] During phacoemulsification, especially in some cases prone to postoperative capsular block syndrome, it is necessary to use capsular scissors to perform radioactive incision of the remaining anterior capsule of the patient who has completed circular capsulorhexis Sometimes it needs to be resected according to the specific situation of the patient's anterior lens capsule. [0003] In the process of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] During the anterior capsulotomy, the depth of entry of the blade can only be judged by the operating medical staff based on experience, and the accuracy of the depth cannot be achieved. In addition, for the different conditions of different patients or the different condit...

AI Technical Summary

Problems solved by technology

[0004] During the anterior capsulotomy, the depth of entry of the blade can only be judged by the operating medical staff based on experience, and the accuracy of the depth cannot be achieved

In addition, for the different conditions of different patients or the different conditions of the two eyes of the same patient, the size of the capsule to be cut is not the same, that is, the bending angle of the blade is different, so the bending angle of the blade needs to be adjusted, so a single curve High-degree capsular scissors cannot achieve precise incisions during surgery
