Problems solved by technology

[0002] The currently used scalpel consists of two parts, the stainless steel blade and the handle. The sharpness of the stainless steel blade will gradually decrease with the wear and tear during use. When the blade becomes blunt, it will affect the stripping and excision of the tissue. prone to corrosion and rust

Abstract

A medical scalpel for the department of ophthalmology is characterized by comprising a handle and a body, wherein both the handle and the body are made of reinforcement phase nickel alloys. A reinforcement phase in an extrusion die barrel comprises aluminium nitride, titanium carbide, silicon nitride, lanthanum nitride and tungsten carbide, and the mechanical performance of the material is improved; by the aid of powder mixing, pressing sintering, annealing, machining, quenching and tempering procedures, manufacturing procedures are simpler, and the cost is reduced.

Description

technical field [0001] The invention relates to an ophthalmic medical device scalpel, which belongs to the technical field of medical devices. Background technique [0002] The currently used scalpel consists of two parts, the stainless steel blade and the handle. The sharpness of the stainless steel blade will gradually decrease with the wear and tear during use. When the blade becomes blunt, it will affect the stripping and excision of the tissue. Corrosion and rust are prone to occur. There is an urgent need for a scalpel that is corrosion-resistant, wear-resistant, and difficult to pollute, and it has sufficient sharpness to fully meet the needs of surgery. Contents of the invention [0003] An ophthalmic medical instrument scalpel, characterized in that the ophthalmic medical instrument surgical knife includes a handle and a knife body, both the handle and the knife body are made of a reinforced phase nickel alloy, and the reinforced phase nickel alloy raw material p...
