Abstract

This Medical needle plays an important role in modern clinical medicine. The penetration and pull process of medical injection needle was simulated by FEM software Abaqus, and the equivalent stress and strain were analyzed. Self-developed mechanical loading equipment was adopted to test the penetration force with different needle tip angles, needle diameters and penetration speeds. The results showed that: the puncture of medical needle into skin was mode I crack. The maximum stress and strain was focused on skin around the tip of needle. The penetration force decreased with needle diameter and penetration speed. The angle of needle tip form greatly affected the penetration force. When the angle of needle tip was 90°, the penetration force reached a maximum value of 708.3 mN, which was 2.21 times that of the needle tip angle 30°. The penetration force of isosceles triangle tip was minimum value.
