Numerical Analysis of Strength Properties of Anatomical General Surgical Tweezers

Abstract

The purpose of the work was to perform a numerical analysis, with the FEM method, of anatomical tweezers loaded with the forces of 10 and 50 N. Tweezers consist of two arms connected permanently by welding and are used for holding tissues. ANSYS software was used for the simulation. The force of 10 N expresses the gripping force during correct handling of tweezers, whereas the force of 50 N simulates a very high load on tweezers. Distribution of stresses, deformations and displacements created during tweezers� work was obtained as a result of the simulations conducted.

“…The finite element method (FEM) is a tool used in engineering and scientific computations, allowing to perform computer simulations identifying the effect of various phenomena and processes on the elements made from specific materials subject to the research [17][18][19][20][21][22][23]. The tool abandons analytical solutions to the problem for the sake of division into finite elements (sections for one-dimensional space) and into distinctive nodes of this division [24][25][26][27][28][29].…”
