Haptic Training Simulator for Pedicle Screw Insertion in Scoliosis Surgery

摘要

Pedicle screw insertion is a common treatment in fixing spinal deformities in idiopathic scoliosis. This paper discusses the development of a haptic device which will aid in training for pedicle screw insertion surgery. By translating the rotational and linear effects of the surgery into tunable haptic parameters, a realistic haptic simulator is created. Over 10 surgeons of varying experience levels used the simulator, and were able to tune the device to what they felt was most realistic. They were also asked to judge the system based on its feasibility and usefulness. The results indicate the simulator is feasible for surgical education.
