PID Model for Real-Time Measurement of Tissue Thickness in Bariatric Surgery

This paper reports the development of PID controller for real-time measurement of tissue thickness in bariatric surgery. The measured thickness is utilized to instantly modify stapling and cutting depths. Bariatric surgery is intended to help people with obesity to lose excess weight and reduce your risk of potentially life-threatening weight-related health problems. This surgery must be safe and completed quickly in order to reduce the risk of developing and experiencing possible side-effects that can sometimes be fatal. Due to this, the linear stapler endocutter, which is the surgical tool used to conduct the surgery, must accurately measure the height of the tissues to be sleeved to ensure a perfect b-shape staple has been put in place. This helps to prevent any dangerous and risky blood leakage, thus allowing a short recovery stay at the hospital. In this paper, we report a PID model of a digital caliper to be embedded in linear staplers currently available in the market to ensure a correct measurement of tissue thickness is taken and consequently an appropriate staple fitting the height of the tissue has been used. The digital caliper will work to stop the firing of the stapler in case the measurements are not correct fit thus preventing any further damage to the tissues from the extra staples and preventing the need for additional firing with the staples.
