A simulator for laparoscopic surgery
The do it yourself guide for any surgeon in the making
Many students and junior doctors want to become surgeons. But do they have the right technical skills? How would they fare during a laparoscopic procedure. Designing, building, and piloting a laparoscopy simulator training box is easy and cheap. You can produce a worthwhile surrogate for laparoscopic surgery for less than £100 (€115; $160).
Four primary challenges differentiate laparoscopic surgery from open surgery. For the simulator to be effective its design must reproduce the real life obstacles1: limited depth perception on a monitor, the fulcrum effect (access ports for the laparoscopic instruments act as a pivot—when the operator moves to the right the instrument will move to the left), reduced tactile feedback, and amplification of the surgeon’s movements. The following design for a video trainer has these obstacles in mind.
The plywood box has an open end to allow ambient light to enter. The box has five ports—two on top and
