Active Bending Thin Scalpel Mechanism Capable of Separating Tissue into a Three-Dimensional Curved Surface

Abstract

We propose an active bending thin scalpel mechanism capable of separating tissue into a three-dimensional curved surface. Many mechanical tools have been developed, however, it has been difficult to separate a tissue into a curved shape. In this paper, we develop a scalpel that can realize active bending motion with a thin structure. The basic principle of the bending is demonstrated, and the prototype scalpel is fabricated. The basic bending experiment is conducted, and the target tissue was separated using the proposed prototype.
