Improvement of depth perception and eye-hand coordination in laparoscopic surgery

摘要

Laparoscopic surgery is a minimally invasive surgical technique which is performed by using an endoscopic camera and long and slender instruments that &e inserted through small incisions in the patient's abdominal wall. The indirect way of observing and manipulating complicates the surgeon's depth perception and disorders the surgeon's eye-hand coordination. This paper describes a concept of an endoscope positioning system that compensates misorientations between the surgeon's hand movements and the movements on the monitor by using a 90° endoscope. Movement parallax is realized by means of an endoscope positioning robot which is controlled by the surgeon's head movements.
