FROM RENDERING TO REALITY WITH 3D TECHNOLOGY – A NEW INTRODUCER FOR GASTRIC BYPASS CIRCULAR ANASTOMOSIS

Abstract

Abstract Introduction A key step during laparoscopic gastric bypass circular anastomosis is the introduction of the stapler through the abdominal wall. The adipose panniculus and the 25mm circular flat surface of the endo-stapler involve a technical challenge. Methods To show the creative process and development of an innovative device designed directly by the surgeon, inspired by the technique of laparoscopic trocar placement for the introduction of the circular endo-stapler into the abdominal cavity. From a render, a digital image created with a 3D model, a realistic appearance is given to the initial idea. Using 3D printers, a first prototype is obtained, later adapted to achieve a safer shape and a more suitable size. Thus, a second prototype was born, meeting the safety and design standards to be used in the operating room. Its design and printing were conducted by a company, complying with patents, and guaranteeing the safety of the material used. Results We present three cases, standardizing the use of the device in the introduction of the endo-stapler and demonstrating its easier passage through the abdominal wall, serving as a guide, giving fluidity and less trauma to the procedure. After performing the anastomosis, we highlight its easy removal using a suture fixed on its peak, which allows it to be safely removed. Conclusions The surgeon is the one who best knows the instruments they need and how to optimize them. 3D technology makes it possible to give life to the innovative ideas of surgeons, for surgeons.
