Abstract: Laparoscopic surgeries are predominant in present day healthcare services due to its reduced hospital stay. However, complex procedure usually increases the discomfort of surgeons. Customized surgical instruments incorporating hand anthropometric measurements and ergonomic factors can solve this issue. The paper addresses this problem by developing prototype of a customized laparoscopic forceps handle using hand anthropometric dimensions. Ergonomic factors included are mass of the tool handle, grip, contact area of the tool with the hand, and wrist posture. The evaluation is completed by collecting subjective ratings and subjects confirmed an enhanced comfort with modified prototype of the handle when compared to existing design of laparoscopic forceps handle.
