title: Use of a linear motion stroke potentiometer as a high precision sensor for linear translation in a laparoscopic ligating loop simulation.
abstract: Virtual Basic Laparoscopic Skills Trainer (VBLaST) is a virtual reality trainer that replicates the Fundamentals of Laparoscopic Surgery (FLS) tasks for training in minimally invasive surgery. For the ligation loop task, we have developed a novel hardware interface using a linear motion stroke potentiometer to accurately sense the linear translation of the ligation loop and a mechanism to attach the tool interface to a PHANToM Omni for force feedback. Testing shows that the interface provided a realistic feel and control of the loop similar to the endoloop device used in FLS ligation loop task.
