A sensor-based minimally invasive surgery tool for detecting tissutal elastic properties(003) 5323219

TLDR

Minimally invasive surgery removes surgeons’ haptic perception, especially of tissue elasticity. The study aims to modify minimally invasive tools to reliably estimate tissue properties for recognition and characterization. The authors prototype a sensor‑based surgical tool by modifying a commercial instrument. Experiments demonstrate that the tool improves surgeons’ haptic perception of tissue.

Abstract

Nowadays, the surgeon who is using minimally invasive tools loses almost completely the haptic perception of the manipulated tissue. In particular, he or she loses the perception of the tissue elastic properties. It is possible to modify the actual mini-invasive surgical tools in such a way that they may give a reliable estimation of the manipulated tissue properties for recognition and characterization purpose. In this paper we present a first attempt to realize a prototype of sensor-based surgical tool using a modified commercial tool. Experimental tests have shown that using such a tool could enhance surgeon's haptic perception of the manipulated tissue.
