Improvement of Depth Perception and Eye-Hand Coordination in Laparoscopic Surgery 1

Abstract

Abstract Laparoscopic surgery is a minimally invasive surgical technique which is performed by using an endoscopic camera and long and slender instruments that are 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.
