Methods and apparatus means of medical scalpels sharpness checking

Abstract

The article is devoted to the development of methods and hardware for scalpels sharpness checking. The necessity of improving the methodology and hardware for scalpels sharpness testing, based on the implementation of the conditions for conducting similar tests of injection needles, is substantiated. The values of piercing force and various materials puncturing time with a scalpel with a sharply sharpened and with a dull point were experimentally determined. Taking into account the revealed high sensitivity of the cellophane film puncture force to the scalpel condition, it has been suggested that it's nessesary to use 40 pm cellophane film as a punctured material when testing its sharpness.
