Description

A kind of ophthalmology scalpel

Technical field

This utility model belongs to technical field of medical instruments, is specifically related to a kind of scalpel.

Background technology

The length of the scalpel that uses at present clinical is fixed, can't regulate as required, often need be equipped with the scalpel of all lengths during operation, has not only increased the cost of medical apparatus and instruments, and in operation, has increased trouble for operation; And the degree of depth that scalpel need cut in the time of can not complying with operation is adjusted.

Summary of the invention

The problem that the degree of depth that this utility model can't be regulated for the length that solves existing scalpel as required and scalpel need cut can not be according to operation the time is adjusted proposes a kind of ophthalmology scalpel.

A kind of ophthalmology scalpel; Described scalpel comprises blade and handle of a knife, and the middle part of the upper surface of handle of a knife is provided with chute along the length direction of handle of a knife, and the middle part of the lower surface of handle of a knife is provided with gathering sill along the length direction of handle of a knife; The length direction of one side channel handle of a knife along the upper edge of handle of a knife is provided with positioning tooth; The tail end of blade is fixedly connected with pushing block, and pushing block is arranged in the chute, and the adjacent side with positioning tooth of pushing block is provided with the positioning convex that matches with positioning tooth; The lower surface of pushing block is fixedly connected with the upper surface of zigzag spring leaf; The lower surface of zigzag spring leaf is fixedly connected with the upper surface of lead, and lead is arranged in the gathering sill, is positioned at the opposite side groove on the upper surface of handle of a knife and is provided with the graduated scale timberline along the place.

This utility model is simple in structure, and the scalpel of this utility model can adapt to different surgical environments through the length of regulating blade, and is easy to adjust, quick; In addition, utilize the scalpel of this utility model,, be convenient to operation in the weight that operation Shi doctor can grasp cutting.

When needs were regulated the length of knife blade, only with hand was pressed pushing block, and promotes pushing block forward or backward; When reaching needed length, unclamp hands, make that the power that is loaded on the pushing block is zero; At this moment, the positioning convex on the pushing block cooperates with positioning tooth, and blade is fixed.
