RT Method applied analysis on practice repetition related operation characteristic measured by surgical scalpel haptic device

Abstract

With the objective of developing a system for surgical scalpel cutting skill training, a prototype specialized for measurement and modeling capabilities was produced, based on the concept of Haptic Recorder. RT method was applied for pattern recognition and discrimination of the scalpel dissection skills between two types of knife and practice sessions. In this report, we propose an inverse analysis method of RT method to generate a target featured reference data from the prerecorded frequent practice trainee. As a simulation, target tool and stage force data are computed in relation to the knife tip position, based on the prerecorded sensor data of dissection of gelatinous substance. The differential data were computed comparing the model data and the actual recorded data of less experienced subject data. The results showed tidy difference to be used to project a guide force to the trainee.
