Abstract Details

2006, MS, University of Cincinnati, Engineering : Electrical Engineering.
The objective of this work is to create or enhance a medical device by providing information on the forces acting on it using sensors that were built with MEMS fabrication techniques. It is important that the device serve a functional purpose as described by the customer or in this case a surgeon that would be using the tool. Many medical tools are quite effective at the task in which they were designed for, but when they are transformed to perform minimally invasive, or robotic surgeries certain tactile elements are lost. This is where it is important to create a way in which these elements can be sensed and translated in such a way so that the physician can seamlessly move from open surgeries to minimally invasive surgeries (MIS) with out losing quality of skills. The goal of this project is to develop force sensors for minimally invasive surgical products. As a proof of concept, a force sensor was developed for a scalpel using silicon as the structure and sensing mechanism. After successful completion of the proof of concept and subsequent feedback from a surgeon, a force sensor was developed for a minimally invasive dissector tool. In this work, force sensors were integrated on a 25 μm thick polyimide film, and rolled onto the exposed surface of a dissector tool. The structure provided a simple, but yet effective way to recognize and characterize forces applied to the tool. This new method shows great possibilities for new low cost, flexible, polymer, tactile sensing systems which could open the door for tactile guided minimally invasive tools.
