[124] Citation: Abstract
The best method of training for laparoscopic
surgical skills is controversial. Some advocate
observation in the operating room, while others promote
animal and simulated models or a combination of surgical
related tasks. The mode of proficiency evaluation common to all of these
methods has been subjective evaluation by a skilled surgeon. In order to
define an objective means of evaluating performance, an instrumented
laparoscopic grasper was developed measuring the force/torque at the
surgeon hand/tool interface. The measured database demonstrated
substantial differences between experienced and novice surgeon groups.
Analyzing forces and torques combined with the state transition during
surgical procedures allows an objective measurement of skill in MIS.
Teaching the novice surgeon to limit excessive loads and improve
movement efficiency during surgical procedures can potentially result in
less injury to soft tissues and less wasted time during laparoscopic
surgery. Moreover the force/torque database measured in this study may
be used for developing realistic virtual reality simulators and
optimization of medical robots performance.
