Analysis of surgical needle insertion modeling and viscoelastic tissue material interaction for minimally invasive surgery (MIS)

Abstract

Soft tissue modeling of surgical events is essential for both considering tissue reactions to surgical instrumentation, in addition, to conducting the design of the surgical instrument. Mainly with observes to surgical needle insertion for minimally invasive surgery (MIS) into soft biological tissue, one of the regularly performed surgical events, many works have been prepared in references to modeling how surgical needles insert the soft biological tissue material as they pass through in the direction of objects deep inside the living body. Deformation of biological soft tissue is one of the important issues, which impacts the surgical needle insert inside the living soft viscoelastic tissue. A needle insertion model is presented to calculate the insertion forces and tissue deformation phenomenon. The experimentations are done on the tissue mimic gel specimens, and the surgical needle insertion-based model for the deformation phenomenon is analyzed to investigate the force model, frictional stress and deflection phenomenon. This study can help to investigate the needle insertion process for analyzing the effect of the surgical needle insertion, which could advance the enactment of several surgical needle insertion-based procedures such as minimally invasive surgery (MIS) and brachytherapy.
