TECHNIQUE AND HARDWARE FOR ASSESSING SHARPNESS OF THE TIP OF SURGICAL NEEDLES

Abstract

The article is devoted to the methodology and hardware for assessing sharpness of the tip of surgical needles. In order to quantify sharpness of the tip of surgical needles, it has been proposed to use a technique for checking this parameter in injection needles based on measuring the maximum effort to pierce a particular material, which should not exceed the normalized value. A device has been created and a methodology for conducting experimental studies has been developed, which allow determining the force acting on a surgical needle when it pierces samples of various materials (office paper, plastic film, cellophane film).
