  • S023023 Virtual reality apparatus for conveying sensation from surgical scissor in soft tissue

抄録

In recently years arthroscopic surgery has been applied extensively to many diseases. It requires a skilled operator's performance because of the narrow view and decreased freedom of motion. The virtual reality simulator, DKASTM(Tol Tech, Inc.), conveys tactile sense from cartilage surfaces, behavior of menisci and tonus of cruciate ligaments but authors have found it lacked cutting sensation. This study attempts develop a system that conveys a cutting sensation to the simulation. In order to get the sensation of cutting, we made an apparatus using two load cells, one measuring cutting strength at the handle and the other measuring cutting resistance, and an actuator which provided the resistance. In the first part of the experiment, six subjects cut porcine meniscus with normal arthroscopic surgical scissors. In the second part of the study, the subjects used the new device to simulate the sensation of cutting porcine meniscus through the force feedback system. Compared to cutting porcine meniscus, the apparatus recorded higher cutting force values. However, all six subjects felt a cutting sensation. In future experiments, the practicality of this system will be improved by allowing a high degree of freedom for the apparatus.
