Fibre Optic Interrogated Palpation Sensor for Mechanical Tissue Assessment in Minimally Invasive Surgery

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The advantages robotic assisted surgery offers compared with conventional laparoscopic surgery has led to increased use in recent years. However, a limiting factor is the lack of physical feedback information for the surgeon. For example, a characteristic marker for cancer location is the stiffness of the soft tissue. Typically, cancerous tissue has a higher stiffness than the surrounding healthy tissue. In this paper, we propose a design for an optical fibre interrogated palpation probe that can be used within minimally invasive robotic assisted surgery. The probe measures the force and displacement applied to the tissue via a flexible membrane. Initial tests have been carried out to measure the stiffness of silicone phantoms. In future, this can be expanded to more complex phantoms with stiff inclusions, and ex-vivo tissue samples.
