Abstract

The invention discloses a surgical knife handle capable of controlling reciprocating cutting of a blade, and relates to the technical field of medical instruments. The surgical knife handle comprisesa knife handle main body; a blade mounting base is movably arranged at the front end of the knife handle main body and used for being connected with the blade; a trigger buckle is arranged at the tailend of the knife handle main body, connected with the blade mounting base through a connecting rod and used for driving the blade mounting base to reciprocate through the connecting rod so as to drive the blade to conduct cutting; and a reset elastic piece is further connected between the trigger buckle and the knife handle main body. The blade can be driven to cut back and forth by pulling the trigger buckle, so that the blade does not need to be controlled to cut back and forth through wrist force, extra operation space is not needed, and smooth operation of an operation is guaranteed.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a scalpel handle capable of controlling reciprocating cutting of a blade. Background technique [0002] In the prior art, during the operation, the handle of the knife is held in hand, and the blade is controlled by the wrist force to incise the surgical site. However, the incision of many minimally invasive surgeries is small, and the operation space required to control the handle cutting by the wrist force is relatively large, which makes ordinary surgery more difficult. The knife does not work. Contents of the invention [0003] The object of the present invention is to provide a scalpel handle capable of controlling the reciprocating cutting of the blade, which can drive the reciprocating cutting of the blade by pulling the trigger, and requires little space for the operation. [0004] The technical solution to achieve the above object is: a scalpel handle that...
