Force Feedback of Dual Force-sensing Instrument for Retinal Microsurgery

Last updated: 02/11/2013

Summary

Retinal surgery is a very delicate procedure requiring small and accurate movements. This procedure can benefit largely from the use of robot, which can reduce error and invasiveness as well as speed up the operation and recovery time. One existing problem with retinal surgery is the maximum acceptable magnitude of force by the tip of the instrument on the eye tissue is below the perceptible threshold. In addition, although the force exerted by the instrument on the sclera is above the sensing threshold, excess force may also be deleterious. It is our goal to test various methods of alerting the surgeon when the force applied to the eye tissue or the sclera is near or past the acceptable range using a novel retinal surgery instrument that is able to sense both the tip and sclera force. From the results, we will be able to conclude which combination of force feedback method provides for optimal operation proceedings.

Goal: To develop and assess different force feedback methods (auditory, haptic, etc.) for a dual force sensing instrument for retinal microsurgery
