Surgical knife with protective sliding sleeve

Abstract

The invention belongs to the field of medical appliances, and relates to a surgical knife with a protective sliding sleeve. The surgical knife mainly comprises a blade, the protective sliding sleeve and a knife handle, and is characterized in that: an elastic button is arranged on the protective sliding sleeve; elastic strips on front and back sides are fixedly connected with the protective sliding sleeve to increase the deformation elasticity of the elastic button and the connection strength of the both, so that the protective sliding sleeve is stably locked on the knife handle after completely wrapping the blade; a top block and an elastic strip convex block with a bevel can cooperatively lighten the pressing force for opening the elastic button; the back side of the body of the knife handle is provided with a groove for sliding the elastic strip convex block to eliminate the frictional resistance of the elastic strip convex block when the elastic strip convex block moves on the knife handle, and solve the problems of a series of related performance required by safe transfer of the surgical knife; highly matched head and neck convexes guarantee that the protective sliding sleeve and the blade therein can be easily assembled on and disassembled from the knife handle so as to improve the safety and convenience of the product in various using links; and the metal tail of the knife handle can be transformed into a plug-in unit for a bit of a safe electric knife so as to widen the usable range of the product in the technical scheme.

Description

Technical field: [0001] The invention relates to a medical operation instrument, in particular to a scalpel and a cutting instrument with a protective sliding sleeve. Background technique: [0002] The severity of blood-borne pathogen infection caused by sharp medical instruments and punctures and cuts to medical workers and users is well known. The development of safe medical sharp instruments has become a research and development goal in the field of medical instrument production. Various types of Therefore, safety scalpels have also appeared on the market one after another. Most of them are products with a blade sheath attached to the handle or structural products that extend and retract the blade in the body of the handle. It is also difficult to meet the clinical requirements of thoroughly cleaning and sterilizing the knife handle after use, so this type of product can only use disposable materials, such as disposable products made of plastic, which not only increases t...

Problems solved by technology

Even so, when these technical products are used in the operation, there are still deficiencies, especially in the safety of the scalpel transfer process, the reliability of the locking of the protective sliding sleeve, and the ease of one-handed operation. Research statistics show that the most common occurrence of scalpel stabs and cuts is in the transmission process, so it is necessary to further improve the existing patented technology to enhance its safety, practicability and versatility
