Abstract

A surgical instrument including a shank, at least one tool mounted for swivel movement at the end of the shank, a swivel element mounted for swivel movement about an axis of rotation for swivelling the tool between an open position and a closed position, and an actuating member actuatable from an end of the shank located opposite the tool for swivelling the swivel element about the axis of rotation. The high closing forces required for plastic deformation of objects can also be achieved without excessive forces being transmitted to the drive mechanisms. The actuating member is an arm which is articulatedly connected at a first articulation point to the swivel element, and that in the open position of the tool, the arm be at an incline to an axis of the swivel element extending perpendicularly to the axis of rotation through the first articulation point and in the closed position of the tool, be essentially perpendicular to the axis of the swivel element.
