Abstract
Provided is a surgical instrument including a first holding member, a sleeve member, a linkage member, a second holding member, a hook member and an opening/closing member. The second holding member is pivotally connected to the first holding member and when the second holding member moves relative to the first holding member, the linkage member is moved inside the sleeve member so as to drive the opening/closing member to move relative to the hook member. Through the movement of the opening/closing member of the surgical instrument, surrounding soft tissues, blood vessels or nerves that have strayed into the hook member can be pushed out so as not to be damaged by the hook member during surgery.
