A Safety Improvement for Laparoscopic Surgery and Other Medical Specialties


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.
