Laparoscopic surgery is an increasingly popular form of abdominal surgical intervention. These procedures are performed using multiple trocars placed in various locations on the abdomen. Current laparoscopic practice and trocar placement creates scarring over the abdomen and improper trocar use can lead to postoperative complications such as hernia formation and bleeding. This project aimed to develop a trocar system that enables the use of multiple trocars in the umbilicus to maximize postoperative cosmetic results and ensure the most minimally invasive procedure. A final stage prototype was designed in SolidWorks and manufactured by stereolithography. Through mechanical testing and data analyzation the design prototypes were validated to have achieved the original project goals.
