All any surgeon wants in the operating room is for the surgery to go as smoothly and successfully as possible. Although laparoscopic surgery is considered a minimally invasive surgery (MIS), there is still some risk, such as accidentally over-puncturing and hitting a vital organ with the trocar.
Nikolai Begg, a PhD candidate at Massachusetts Institute of Technology, has identified this as a major issue and has engineered a way to overcome it. When a traditional trocar is used, the surgeon applies force to penetrate the layer of tissue. However, once the trocar has breached a specific tissue layer, the surgeon experiences a decrease in resistance. With the decrease of resistance and the same force applied, the trocar can potentially accelerate and puncture internal organs. By studying the physics behind a puncture, Beggs designed a device using simple principles of friction and a spring to make this part of a surgical procedure safer.
