Scalpel

Abstract

The invention relates to a scalpel which comprises a blade, a scalpel handle and a scalpel rest. The blade and the scalpel handle are integrally formed. The blade comprises a body part and cutting edge parts, the cutting edge parts comprise the first cutting edge part and the second cutting edge part, the first cutting edge part is longer than the second cutting edge part, and the included angle a1 between the first cutting edge part and the medial axis of the blade is smaller than the included angle a2 between the second cutting edge part and the medial axis of the blade. The scalpel handle comprises a holding part and a connection part, the holding part is arranged at the front end of the scalpel handle and has a radian, the connection part is arranged at the rear end of the scalpel handle and provided with threads, a cylinder structure with built-in threads is arranged at the front end of the scalpel rest, and the rear end of the scalpel rest is arranged to be of a regular hexahedron structure. The scalpel is simple in structure, insertion depth of the scalpel can be accurately controlled, mechanical strength and sharpness of a cutting edge can be ensured, and operation quality is improved.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a medical surgical scalpel. Background technique [0002] The scalpel is a commonly used medical device, especially a very important tool in medical surgery, which provides a strong guarantee for human health; the scalpel generally includes a blade and a handle, usually the blade and The handle of a knife is set separately, and the blade is clamped on the handle of a knife during use, which easily causes the blade to loosen and causes inconvenience to the user; the blade in the prior art is generally made of metal materials, but because the blade is in the During the production process, the angle setting of the blade is unreasonable, resulting in insufficient strength of the blade, resulting in weak operation, and affecting the quality of surgery; in addition, the insertion depth of the existing surgical blades is based on the work experience of doctors, who generally master th...
