摘要

PURPOSE: A current-rotating type surgical instrument is provided to easily rotate an operation head by using a current applied from outside. CONSTITUTION: An operation head(10) is connected with a support stand(20) which can be rotated. One side of a driving link(18) is connected with one side of the operation head. The driving link moves according to the longitudinal direction of a current-rotating type surgical instrument and rotates and drives the operation head. A driving body(60) is connected with the other side of the driving link. The driving body is transformed by a current applied from outside and operates the driving link. The driving body is placed between a top ring and a bottom ring. The top ring moves with the driving link. One side of the driving link is fixed to the bottom ring.
