Abstract

The invention discloses a making method of a minimally invasive scalpel. One end of a blade is a cutting edge and the other end is provided with an inserting part; a lower bolt rod is screwed into a lower threaded hole and is embedded into a lower concave hole of the inserting part; a plurality of blood suction holes are formed in the cutting edge, and the blood suction holes communicate with a liquid collection tube via branch catheters; a chamfered inclined plane is arranged at the upper side of the cutting edge; a rubber sleeve sleeves the middle-rear part of a strip-shaped scalpel handle;and a plurality of convex points are uniformly distributed on the outer surface of the rubber sleeve. The blade is made by the following steps: crushing the following materials in a pulverizer: 50-60parts 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. According to the minimally invasive scalpel obtained by the making method provided by the invention, the blade of the scalpel is ultrahigh in hardness, and moreover, the blade, which is forged is quite sharp and is quite high in intensity so as to avoid easy bending; the minimally invasive scalpel is stable and reliable; and three-dimensional location is achieved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a method for manufacturing a minimally invasive 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 ex...
