Surgical instrument
First Claim
1. A surgical instrument, comprising:
- a shank having a longitudinal axis and an inner width;
at least one swiveling tool including a first tool which is mounted for swivel movement at the end of said shank;
a second tool which opposes said first tool;
a first swivel element which is mounted for swivel movement about an axis of rotation for swiveling said first tool in a range of motion between a first position and a second position; and
a first actuating member actuatable from an end of said shank which is located opposite said first tool for swiveling said swivel element about said axis of rotation;
wherein;
said first actuating member comprises an arm which is articulatedly connected to said first swivel element at a first articulation point;
said arm is adapted to position said first tool in said first position when said arm is at an incline to an axis of said first swivel element and at an incline to said shank axis;
said axis of said first swivel element extends perpendicularly to said axis of rotation through said first articulation point;
said arm is adapted to position said first tool in said second position when said arm is approximately perpendicular to said axis of said first swivel element and almost perpendicular to said shank axis; and
a length of said arm corresponds almost to said inner width of said shank.

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.
