ABSTRACT: Laparoscopic surgery is a new abdominal surgical procedure which
helps the patients in many ways like less hospital stay, faster recovery and
reduced pain. The main disadvantage in this surgical procedure is the reduced
haptic perception by the surgeons due to the usage of laparoscopic instrument
to handle tissues which in turn cause damage of it as compared to an open
surgery. The primary aim of this investigation was to compare the pinch force
applied during two different methods of laparoscopic grasping: Finger and Palm
grasp. A low cost force sensing resistor tailor made for the grasper tip was
designed and fabricated for quantifying the grasper tip force in the study. The
results indicate more pinch force was applied during palm grasp as compared to
finger grasp so as to prevent the slippage of the tissues from the jaws of the
laparoscopic graspers.
