Abstract
A clamping device, preferably for use on a retractor support, has an upper clamp and a lower clamp. The clamps include a movable jaw and a fixed jaw pivotal between a locked configuration and an unlocked configuration which both locks the clamps in a shut configuration and fixes the angular position of the clamps relative to one another. A drawbar and cam act together to compress the upper and lower clamps into a clamping or locking position.
Claims21
A surgical clamp apparatus comprising:
- a first clamp having first and second jaws pivotally attached to each other;
- a second clamp having first and second jaws pivotally attached to each other, said second clamp connected to the first clamp and rotatable relative to the first clamp in an unlocked configuration;
- first and second serrated locks located between the first and second clamp, wherein said first serrated lock is connected to the first clamp and the second serrated lock is connected to the second clamp;
- wherein the serrated locks are in contact with one another thereby fixing the angular relationship of the first clamp relative to the second clamp in a locked configuration, and
- the serrated locks are spaced apart from one another in the unlocked configuration allowing the second clamp to rotate relative to the first clamp.

A surgical clamp apparatus comprising:
- a first clamp member having a first jaw and a second jaw pivotable at a pivot point relative to the first jaw, said first clamp having a bore extending therethrough, said second jaw connected to a first lever arm with a pivot point intermediate the first lever arm and the second jaw, said first lever arm having a channel therethrough;
- a second clamp member having a first jaw and a second jaw pivotable relative to the first jaw, said second clamp having a bore extending at least partially therethrough, said second jaw connected to a second lever arm with a pivot point intermediate the second lever arm and the second jaw, said lever arm having a channel therethrough;
- a drawbar extending through the bore of the first clamp and through the channel of the leg of the first clamp and at least partially into at least one of the bore of the second clamp and the channel of the leg of the second clap, said drawbar having a proximal end with a head and a distal portion, said head having a gripping surface connected thereto;
- and
- a cam configured to cooperate with the distal portion of the drawbar, wherein movement of the drawbar from an unlocked configuration to a locked configuration moves the cam from an unlocked configuration to a locked configuration with said cam member moving toward the proximal end of the drawbar and securing the second lever arm and the second clamp in a locked configuration.

A surgical clamp apparatus comprising:
- a first clamp having a first jaw and a second jaw pivotable at a pivot point relative to the first jaw, said first clamp having a bore extending therethrough, said second jaw connected to lever arm opposite a gripping surface about the pivot point;
- a second clamp connected to the first clamp member;
- and
- wherein said first clamp member is spring biased into a closed configuration in an unlocked position, and locked in the closed configuration in a locked configuration.
