Processing method of surgical blade and scalpel

Abstract

The invention belongs to the field of medical apparatus and instruments, and provides a processing method for a surgical blade and a surgical knife. The blade is made of zirconia ceramics, a knife blank is formed by adopting the tape casting process, equipment adopted to grind the surface of the knife blank is a vertical type knife grinder, and the grinding linear velocity of the vertical type knife grinder is 2080-2640 meters per minute; big knife-edge processing is performed, equipment adopted in the big knife-edge processing step is a first horizontal type numerical control knife grinder, and the grinding linear velocity of the first horizontal type numerical control knife grinder is 2630-3270 meters per minute; surface tumbling is performed; small knife-edge processing is performed, equipment adopted in the small knife-edge processing step is a second horizontal type numerical control knife grinder, and the grinding linear velocity of the second horizontal type numerical control knife grinder is 2520-3150 meters per minute. According to the surgical blade, the surface is smooth, the sharpness is high, and the service life is longer than a surgical blade made of metal materials; in addition, the tape casting process is adopted to form the blank, therefore, the density is high, outside impurities can be prevented from entering, the product appearance and the finished product strength can be easily guaranteed.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a processing method of a scalpel and a surgical blade used in medical surgical operations. Background technique [0002] The scalpel is a very important tool in medical surgery, which provides a strong guarantee for human health. A scalpel generally includes a blade and a handle, and the blade is generally made of metal material. [0003] The most commonly used metal material is stainless steel. The blade of a stainless steel scalpel will have a serrated structure during processing. Although this serrated structure is very fine and difficult to identify with the naked eye, it is easy to cause scars after surgical operations using this scalpel. In addition, scalpels made of metallic materials run the risk of diffusion of metallic elements, thereby contaminating the wound. In addition, scalpels made of metal materials have a short service life and need to be replaced regularly,...

Problems solved by technology

[0005] Because zirconia ceramics have many excellent characteristics, if it can be applied to surgical blades, it will significantly improve the performance of surgical blades. However, due to the complexity of processing zirconia ceramics and the special industry standards in the field of medical devices, the existing technology Supplied surgical blades or scalpels made of zirconia ceramics do not meet requirements or are less satisfactory
