Description

A kind of tumor cutting scalpel

Technical field:

This utility model relates to scalpel technical field, particularly a kind of tumor cutting scalpel.

Background technology:

At present, treatment tumor the most effectively, method is performed the operation exactly the most thoroughly, operation will be used scalpel, existing scalpel is made up of cutter head and handle of a knife, and this scalpel is in the time doing tumor cutting, owing to there is no safeguard procedures, cutter head is easy to injure contiguous normal structure, even more serious while particularly cutting deep tumor, increase work difficulty to medical worker, also easily cause malpractice simultaneously.

Summary of the invention:

The purpose of this utility model is to overcome the shortcoming existing in prior art, and a kind of easy to operate tumor cutting scalpel with being difficult for injuring normal structure is provided.

To achieve these goals, this utility model provides a kind of tumor cutting scalpel, comprise cylindrical knife shank, wherein, front end face the first half of described handle of a knife is provided with cylindrical cutter head guard column, it is leg-of-mutton cutter head that front end face the latter half of described handle of a knife is provided with the cross section being connected with described cutter head guard column, the front end arranged outside of the outside of described cutter head and described cutter head guard column and described handle of a knife has protective cover, the fore-end that is positioned at the described protective cover in the outside of described cutter head and described cutter head guard column is semicircle annular, the rear end part that is positioned at the described protective cover in the front end outside of described handle of a knife is annular, the rear end of described protective cover is vertically installed with riffled tube, described riffled tube female thread is connected with fastening bolt, on the outer wall of described handle of a knife, be provided with graduation mark.

This utility model outstanding advantages is: simple in structure, when use, the front end of protective cover is adjusted to the lower end that is positioned at cutter head outside, tighten fastening bolt, cutter head is stretched to tumor site by operative incision, screwed tightening fixing bolt, by protective cover Rotate 180 degree or according to graduation mark, protective cover is moved to suitable distance backward, tumor is cut with cutter head, easy to operate, because cutter head top is provided with cutter head guard column, and cutter head arranged outside has protective cover, can effectively avoid cutter head to stretch in process, may the injury causing to the tissue between tumor site and tumor site adjacent tissue to operative incision, also the injury that can effectively avoid the flat knife back of traditional cutter head to cause adjacent tissue, simultaneously in cutting process, can also control the naked length of leaking part of cutter head, can control the degree of depth or the length of cutting, thereby the injury of avoiding cutter head may cause adjacent tissue.
