The PC Mouse as a Learning Tool for the Development of Eye-Hand Coordination for Trainees in Laparoscopic Surgery

摘要

The introduction of laparoscopic surgery brought with it psychomotor challenges to the surgeon; notably, eye-hand coordination. This phenomenon is caused by a combination of field-video displacement, instrument movement distortion, depth misperception and tactile stimulus deprivation. Skill acquisition in laparoscopic surgery is time-dependent, as it is an adaptive reori-entation of the brain to the unusual. Since much of the training period in laparoscopic surgery is used for mastering eye-hand coordination, it is conceivable that exercises that mimic the actual situation would cut down on the time required to attain expertise.In open operations, the direction of intended and resultant motion are the same. Should the same instruments used in laparoscopic surgery be employed in open operations for the same procedures, they would be handled and used like type three levers, wherein the fulcrum is proximal, the effort is in the middle, and the load is distal. However, when employed in laparoscopic surgeryin the presence of immovable ports, the
