Abstract
The present invention relates to surgical clamps and clamp devices that provide a handle-free surgical field. The clamp jaws may be opened or closed by a rotationally or translationally moveable drive element that may be actuated from a position proximal or distal to the jaws. The surgical clamps may also be deployed using a clamp applier which slidably engages the clamp along a wire to releasably attach itself to the clamp.

A surgical clamp comprising
- first and second body portions having proximal and distal ends, the proximal ends being pivotally connected, and said first and second body portions further comprising first and second jaw portions inserted into the first and second body portions respectively;
- a rotational drive element connected between the first body portion and the second body portion and axially aligned with the body portions when the first and second jaw portions are in a clamped position, such that movement of the drive element pivotally moves the body portions relative to one another;
- a drive shaft extending proximally from the drive element;
- and
- an actuating knob mounted on the drive shaft, the actuating knob including a first knob portion with a grooved grasping surface and a second knob portion rotatable and translationally immobile relative to the body portions and the first knob portion, wherein the drive shaft extends through and is rotatable relative to the first knob portion.
