Abstract
The invention relates to an improved scalpel which comprises a cylindrical scalpel handle. A sliding groove is formed from one end face of the scalpel handle to the other end face of the scalpel handle. The section of the sliding groove is round. A sliding base is installed in the sliding groove in a sliding mode. A blade is detachably connected to one end of the sliding base. A push rod is fixedly installed on the outer cylindrical face of the sliding base, extends out of the outer side of the scalpel handle and can slide along the scalpel handle. The outer side of the scalpel handle is connected with a ring through a metal wire. By means of the arrangement of the sliding groove, when the scalpel is not used, the blade of the scalpel can be hidden in the sliding groove, and medical staff are prevented from being hurt. The sliding base is arranged so that the blade can be detached and installed conveniently. The ring is arranged so that the scalpel can be effectively prevented from slipping off from hands in use.
Description
Technical field
The present invention relates to technical field of medical instrument, particularly relate to a kind of modified model scalpel.
Background technology
The scalpel that in hospital, surgeon uses divides blade and handle of a knife.Blade is disposable, and handle of a knife is not.Other apparatus neither be disposable, but be all through autoclaved when each use.All microorganisms are killed in so-called sterilizing exactly.The holding mode of current scalpel is divided into following five kinds: 1, hold bow formula: the most frequently used one holds cutter mode, and actuating range is wide and flexibly, firmly relates to whole upper limb, mainly at wrist, for the incision etc. of longer skin incision and theca of rectus abdominis muscle.2, pen-holding type: firmly soft, flexible operation is accurate, is convenient to the dynamic degree controlling cutter, its action and strength mainly at finger, for short and small otch and delicate procedure, as dissected blood vessel, nerve and incision peritoneum etc.3, holding: full hands grips handle of a knife, and thumb and forefinger tightly pinch handle of a knife indentation place.This method control cutter is more stable.The main activity force operated is shoulder joint, hard thick, the firmly larger incision of, tissue wide for cut coverage, as amputation, tendon incision, longer skin incision etc.4, instead choose formula: a kind of transition form being pen-holding type, blade is teasing upwards, in order to avoid damage deep tissue.First thrust during operation, dynamic point is at finger.For cutting the hollow organs such as abscess, blood vessel, trachea, common bile duct or ureter, cutting off the tissue of clamp or expanding skin incision etc.5, finger pressing type: firmly heavy, forefinger pushes down handle of a knife front end, and later half end is hidden in hands.This method control cutter is slightly dumb.Mainly be applicable to the skin histology being difficult to cut.
At present, in use, there is following problem in scalpel: 1, when blade fractures, then need separately to change, troublesome poeration, wastes time and energy, and adds great work difficulty to medical worker; 2, when performing the operation to patient, handle of a knife is easy to slippage in hands, thus causes malpractice, adds work difficulty to medical worker; 3, when blade is not when using, easy scratch medical personnel.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of modified model scalpel.
The present invention is achieved through the following technical solutions:
A kind of modified model scalpel, comprise handle of a knife, described handle of a knife is cylindrical, one end along described handle of a knife offers chute on direction, other end, and the cross section of described chute is circular, and is slidably fitted with slide in described chute, and be removably connected with blade in one end of described slide, and catch bar is installed with on the external cylindrical surface of described slide, described catch bar stretches out the outside of handle of a knife, and can slide along described handle of a knife; The outside of described handle of a knife is connected with an annulus by tinsel, effectively prevents scalpel landing from hands.
As the preferred technical solution of the present invention, on the length direction of described blade, offer graduation mark.
As the preferred technical solution of the present invention, described slide is in " convex " shape structure.
Compared with prior art, the invention has the beneficial effects as follows: 1, by being provided with chute, like this when not using, can the blade of scalpel is hidden in chute, prevent from producing damage to medical worker; 2, slide is provided with, blade easy for removal and installation; 3, by being provided with annulus, in use, scalpel landing from hands can effectively be prevented.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
Described a kind of modified model scalpel, comprise handle of a knife 10, described handle of a knife 10 is cylindrical, on direction, other end, chute 20 is offered along one end of described handle of a knife 10, the cross section of described chute 20 is circular, and slide 30 is slidably fitted with in described chute 20, and be removably connected with blade 40 in one end of described slide 30, described slide 30 is in " convex " shape structure; And catch bar 300 is installed with on the external cylindrical surface of described slide 30, described catch bar 300 stretches out the outside of handle of a knife 10, and can slide along described handle of a knife 10; The outside of described handle of a knife 10 is connected with an annulus 60 by tinsel 50.By being provided with chute, like this when not using, can the blade of scalpel be hidden in chute, prevent from producing damage to medical worker; Be provided with slide, blade easy for removal and installation; By being provided with annulus, in use, scalpel landing from hands can effectively be prevented.
On the length direction of described blade 40, offer graduation mark 70, be convenient to control depth of cut, alleviate the work difficulty of medical worker.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
