Problems solved by technology

The steel-handled scalpel is mainly composed of a disposable blade and a non-disposable steel handle. Before use, the blade needs to be installed on the handle, and the blade is removed from the handle after use; It is difficult to avoid the problem of shaking and loosening, and the cutter head may fall off under external force, which is extremely dangerous

Abstract

The invention discloses a non-slip surgical scalpel, which comprises a blade and a strip-shaped scalpel handle. A making method comprises the following steps: I, crushing the following materials in apulverizer: 50-60 parts of superfine tungsten carbide, 12-20 parts of strontium titanate, 8-10 parts of titanium carbide, 6-8 parts of chromium carbide, 4-8 parts of molybdenum disilicide, 7-9 parts of titanium nitride, 1-2 parts of vanadium carbide and 3-4 parts of graphite powder, so that mixed powder, which is less than 20mm in diameter, is formed; II, heating the mixed powder obtained from thestep I to 850 DEG C under a vacuum condition for 4h, then adding 4-6 parts of phenolic resin, fully stirring all materials uniformly so as to obtain a mixture, and cooling the mixture; III, forming and pressing the mixture via a press machine, so that a pressed blank is formed; and IV, sintering the pressed blank in a sintering furnace, so that a blade blank is formed. According to the multifunctional scalpel provided by the invention, the cutting edge is sharper, and hard tissues can be cut open quite easily; and the blade is quite shape, quite high in intensity and cannot get bent easily.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an anti-skid surgical scalpel. Background technique [0002] The scalpel is an essential tool for surgical operations, and its safety is of paramount importance to surgeons and patients. In the past, there are usually two types of traditional scalpels: one is a plastic handle scalpel, and the other is a steel handle scalpel. The plastic handle scalpel is mainly composed of a disposable blade and a disposable plastic handle. The front part of the plastic handle is provided with a blade holder, and the blade is installed on the blade holder. The steel handle scalpel is mainly composed of a disposable blade and a non-disposable steel handle. Before use, the blade needs to be installed on the handle, and the blade is removed from the handle after use; It is difficult to avoid the problem of shaking and loosening, and the cutter head may fall off under external force, which is ext...
