Abstract

The utility model relates to a telescopic safety scalpel, and belongs to the field of medical apparatus and instruments. The scalpel can effectively solve the problem that the existing scalpel blade is bare to easily cut medical staff and cleaning staff. The scalpel comprises a casing, a knife rest, a locking key and a spring. The casing is provided with a knife rest fixing groove, a locking key sliding groove, a locking key fixing hole and a spring baffle plate; the locking key is arranged on the knife rest, and is connected with the knife rest through a spring piece; and the spring and a spring fixing cap are arranged at the tail of the knife rest. One end of the spring piece is welded on the knife rest, and the other end of the spring piece is welded on the locking key. When the medical staff uses the scalpel, the locking key is pushed to the locking key fixing hole to expose the blade, and the locking key is tightly held to use the scalpel. When the scalpel is used up, the locking key is loosened and is automatically popped up, and the blade shrinks in the casing along the knife rest under the effect of the spring so as to achieve the purpose of protecting the medical staff; and the scalpel is simple, feasible, safe and reliable.

Description

The retractable safety scalpel

Technical field

This utility model provides a kind of retractable safety scalpel, is applicable to protect in the operation process medical personnel and cleanup crew's safety, belongs to medical instruments field.

Background technology

In the market medical scalpel and blade, great majority do not have safety guard, and blade is exposed, very easily hurts medical worker and cleanup crew, the threat that easily causes medical worker and cleanup crew's blood-borne pathogens to infect.Sometimes also very easily cause patient's secondary injury after the scalpel slippage.Telescopic surgical knife on the market exists operating process loaded down with trivial details, complicated now.Disclose a kind of retractable safety scalpel based on above reason, it has the advantages such as easy and simple to handle, safe.

Summary of the invention

For solving the exposed easily incised wound medical worker of present scalpel blade and cleanup crew's problem, this utility model provides a kind of Telescopic surgical knife, can effectively solve the exposed easily incised wound medical worker of scalpel blade and cleanup crew's problem, guarantee medical worker and patient's safety.

The technical scheme that its technical problem that solves this utility model adopts is: it is comprised of overcoat, knife rest, trivial key, several parts of spring.Knife rest holddown groove, trivial key sliding tray, trivial key fixing hole, spring stop have been put outward; Trivial key is arranged on the knife rest, and trivial key links together by spring leaf and knife rest, and the knife rest afterbody has spring and spring locking cap.Spring leaf one end is welded on the knife rest, and the other end is welded on the trivial key.

The beneficial effects of the utility model are: this utility model can effectively solve the exposed easily incised wound medical worker of scalpel blade and cleanup crew's problem, guarantees medical worker and patient's safety.And easy, easy row, safety, reliable.

The specific embodiment

This utility model retractable safety scalpel is to implement like this, and it is comprised of overcoat (1), knife rest (10), trivial key (5), several parts of spring (7).Knife rest holddown groove (2), trivial key sliding tray (3), trivial key fixing hole (4), spring stop (6) are arranged on the overcoat (1); Trivial key (5) is arranged on the knife rest, and trivial key (5) links together by spring leaf (9) and knife rest (10), and knife rest (10) afterbody has spring (7) and spring locking cap (8).Spring leaf (9) one ends are welded on the knife rest (10), and the other end is welded on the trivial key (5), and blade holddown groove (11) is used for installing blade.When medical personnel use this scalpel, promote trivial key to trivial key fixing hole place, expose blade, clutch trivial key, use scalpel.Finish using, unclamp trivial key, trivial key is upspring automatically, the effect bottom knife of spring with knife rest retraction overcoat in, reach protection medical worker's purpose, and easy, easy row, safety, reliably.

Claims

1. the retractable safety scalpel is characterized in that it comprises overcoat, knife rest, trivial key, spring, has put knife rest holddown groove, trivial key sliding tray, trivial key fixing hole, spring stop outward; Trivial key is arranged on the knife rest, and trivial key links together by spring leaf and knife rest, and the knife rest afterbody has spring and spring locking cap; Spring leaf one end is welded on the knife rest, and the other end is welded on the trivial key.
