Disposable safety scalpel

Abstract

The invention discloses a disposable safety scalpel, and belongs to the field of a medical apparatus; a knife sheath is formed by buckling and connecting two matched protecting bodies, wherein a knife handle is arranged at the back end of the knife sheath; a sliding base which is capable of sliding forward and backward along the protecting bodies is arranged in a hollow cavity inside the knife sheath in a matched mode; a knife clamping convex block is arranged on the side face of the front end of the sliding base, and a blade is clamped on the knife clamping convex block; a plurality of toothed grooves are formed on the part, positioned at the top of the hollow cavity, in any one of the protecting bodies; an elastic plate is correspondingly arranged on the sliding base; toothed bumps are formed on the tail end of the elastic plate; the toothed bumps correspond to the toothed grooves; a pressing handle is connected to the middle of the elastic plate; an elastic hook head is arranged at the tail end of the sliding base, and a locking clamping block is arranged on the corresponding protecting body; and the elastic hook head can pass over the locking clamping block and hook the locking clamping block when the pressing handle is pushed and squeezed backwards. The scalpel disclosed by the invention is simple in structure and convenient in operation, the extension length of the blade can be conveniently adjusted, and misoperation is not easily caused; the scalpel, after being used, is convenient to lock; and the scalpel is disposable only, so that the scalpel is safer to use.

Description

technical field [0001] The invention relates to a medical device, in particular to a disposable scalpel. Background technique [0002] In the Chinese patent database, a one-time use safety scalpel is disclosed. Its application number: 201410228377.2; application date: 2014-05-27; publication number: 103976776A; publication date: 2014-08-13. It is composed of a blade, a knife handle and a knife cover. When the knife cover slides back and forth relative to the knife handle and is positioned, the blade presents two states of protruding and retracting from the knife cover. A first The locking opening, the knife guard locking opening and the first locking opening are transitioned through an inclined surface or an arc surface; a second locking opening and a blocking block are arranged in front of the through groove on the front of the knife handle. When the button is pressed, when the knife cover is pushed forward, because the bumper is intercepted by the blocking block, the bump...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. During the sliding process of the protective cover, the buckle point may be broken and exposed to the outside, which is very prone to medical accidents

2. The use length of the blade cannot be adjusted, because the medical staff cannot adjust the length of the blade according to the size of the patient's trauma when using it

3. In the process of performing surgery, if the medical staff takes a long time, they will be easily fatigued, and they will easily slip when using the scalpel

4. The blade allows patients to see it intuitively, and it may cause fear in their hearts

5. There is a possibility of misoperation. If it enters the locked position by mistake during the operation, it will affect the progress of the operation and delay the treatment time of the patient.
