Project Overview

Current minimally invasive laparoscopic surgical tools are insufficient in their ability to grasp and hold a large amount of the bowel without causing injury to the patient when performing surgery. A new tool suited to this task by providing feedback (auditory or tactile) to the surgeon is necessary. The goal is to reduce injury due to excessive pressure to the bowel organs during laparoscopic surgery.
