Investigating the muscle activities of performing surgical training tasks using a virtual simulator.
ABSTRACT The objective of this study was to determine the muscle activities of upper extremities while performing fundamental surgical training tasks using a virtual simulator. Six subjects performed virtual cutting tasks and their muscle activities of upper extremities were measured. The results demonstrated a significant increase in muscle activities in both proximal and distal upper extremities, which are the common areas of occurrence of injury after prolonged practice. This study suggests that the upper trapezius and the extensor digitorum are essential prime movers to perform surgical training tasks. These muscles should be monitored for performance assessment in future studies.

ABSTRACT: Abstract A modular control interface and simulated virtual reality environment were designed and created in order to determine how the kinematic architecture of a control interface affects minimally invasive surgery training. A user is able to selectively determine the kinematic configuration of an input device (number, type and location of degrees of freedom) for a specific surgical simulation through the use of modular joints and constraint components. Furthermore, passive locking was designed and implemented through the use of inflated latex tubing around rotational joints in order to allow a user to step away from a simulation without unwanted tool motion. It is believed that these features will facilitate improved simulation of a variety of surgical procedures and, thus, improve surgical skills training.Journal of Medical Engineering & Technology 09/2013; DOI:10.3109/03091902.2013.831492
