Abstract
The invention discloses an operating knife handle which comprises a knife handle body. An extension rod is arranged at one end of the knife handle body, a convex block is fixedly arranged at one end of the knife handle body, four round holes are symmetrically formed above and below the convex block, a spring and a steel ball are arranged in each round hole, each steel ball is arranged at one end of the corresponding spring, a groove is formed in one end of the extension rod, and limiting holes are symmetrically formed above and below the groove. The operating knife handle is simple in structure, reliable in connection, adjustable in length according to needs, capable of reducing an operating opening and reducing suffering of patients and easy to popularize and use.
Description
Technical field
The present invention relates to field of medical device, especially relate to a kind of blade holder.
Background technology
Traditional blade holder is enough long, when carrying out some little wound operations because the less hands in space puts in inconvenient operation, will reach into when performing an operation, and leave can viewport, wound is comparatively large, is unfavorable for that the later stage of patient recovers, also larger to the wound of patient.
Summary of the invention
The present invention solves the shorter problem can not carrying out little wound operation of current scalpel, for herein is provided a kind of blade holder, comprise handle of a knife body, described handle of a knife body one end is provided with extension bar, and one end of described handle of a knife body is fixedly installed projection, and the upper and lower of described projection is symmetrically arranged with four circular holes, spring and steel ball is provided with in described circular hole, described steel ball is arranged on one end of spring, and one end of described extension bar is provided with groove, and the upper and lower of described groove is symmetrically arranged with spacing hole.
As preferably, the rear portion of described extension bar is provided with anti-skidding raised line.
As preferably, described projection is identical with the shape of groove, and shape of cross section is trapezium structure.
The invention has the beneficial effects as follows: mechanism of the present invention is simple, connect reliable, the length of blade holder can be regulated as required, the opening of performing the operation can be reduced, reduce the misery of patient, be easy to promote the use of.
