3D Printed Single Incision Laparoscopic Manipulator System Adapted to the Required Forces in Laparoscopic Surgery

摘要

3D printing in medical technology is mainly used to produce customized devices for surgical planning or surgical guides and templates. However, for laparoscopic systems, 3D printing is hardly used. A challenge is the transmission of the necessary forces required in laparoscopic surgery. We designed and manufactured a 3D printed customizable manipulator system for Single Incision Laparoscopic Surgery (SILS), fulfilling the force-related requirements in laparoscopic surgery. The Single Incision Laparoscopic Manipulator System can apply forces at its tip up to 5.6 N with acceptable operating forces not exceeding 30 N. We showed the functionality of the manipulator system in a manipulation experiment in comparison to standard SILS instruments.
