Abstract
Minimally invasive surgical (MIS) procedures of the gastric tract often involve resection of tissues such as the bowel, colon or part of the stomach. Modern surgical trends point toward surgical robotics being more and more widely applied, but manual laparoscopy is still prevalent. We believe that gathering large quantities of mechanical data through tissue characterization is fundamental for the improvement of laparoscopic tools and procedures. A crucial feature of small-scale integrated measurement systems is the coverage of the sensor and the accompanying readout electronics. In our work we intended to test our proprietary MEMS force sensor developed by HUN-REN CER’s Microsystems Lab for in-situ tissue characterization by integrating it into a stapler currently used in medical practice. Using a flexible printed circuit board (PCB) carrier and customized 3D printed enclosures, a series of stapler-compatible sensorcasings were developed. These were tested both with hard cover used in our tabletop measurement system [1] as well as combining with polydimethylsiloxane (PDMS) to evaluate its effectiveness as a biocompatible sensor encapsulation.
