Patent ID: 8758392

Claim:
A closing assembly for a clamping device having first and second jaw members, comprising: a closing mechanism connected between the first and second jaw members, the jaws extending distally from the closing mechanism, wherein the closing member comprises a rotatable member and a drive member for rotating the rotatable member, wherein the drive member comprises a flexible member passing around the rotatable member for pulley-like rotation of the rotatable member responsive to movement of the flexible member; and means for applying a separating force to the first and second jaw members proximally of the closing mechanism, whereby the first and second jaw members can be maintained substantially parallel during closing, wherein the rotatable member is rotatably mounted relative to one jaw of the first and second jaw members, and wherein the closing mechanism further comprises a link member movably connected between the other jaw of the first and second jaw members and the rotatable member, whereby rotation of the rotatable member moves the first and second jaw members between an open and a closed position, wherein the rotatable member comprises a disk, and wherein the disk is mounted to the one jaw at a non-centric point relative to the disk, and wherein the link member is also mounted to the disk at another non-centric point relative to the disk.
