title: The use of a GripForce system to map force distribution patterns of laparoscopic instruments.
abstract: While it is acknowledged that the forces required to manipulate laparoscopic instruments can be significant and are important in terms of potential discomfort after prolonged use, no systematic study has been conducted. In this paper we present a GripForce system that allows for the mapping of force distribution patterns of laparoscopic instruments. Initial results showed significant differences in force distribution between various instrument handles, thus demonstrating the viability of the system and proposed methodology. Analysis of force distribution patterns of laparoscopic instruments can help towards improving instrument design, better understanding the relationship between force applied and performance, as well as provide useful feedback to trainees and surgeons.
