Laparoscopic surgical clamp
First Claim
1. A surgical clamp having a longitudinal configuration and an axis extending between a proximal end and a distal end, the clamp comprising:
- a support structure;
first and second opposed jaws coupled to the support structure, the first jaw being pivotally attached to one of the support structure and the second jaw and the jaws being operable between an open state wherein the first jaw is spaced from the second jaw to accept a body conduit, and a closed state wherein the jaws are proximate to at least partially occlude the body conduit;
means for biasing the first jaw to the open state;
portions of the first jaw defining a beveled surface which is disposed at an angle to the axis of the clamp;
means carried by the support structure and movable relative to the support structure for engaging at least the first jaw to move the first jaw relative to the second jaw between the open state and the closed state; and
a screw included in the engaging means and disposed at the proximate end of the clamp, the screw being operable to move axially along the beveled surface of the first jaw in the open state to move the first jaw toward the closed state.

Abstract
A surgical clamp combination includes a clamp movable between a free state and operable state, the clamp including a pair of jaws which can be operated to occlude a body conduit. A clamp applier is adapted to releasibly engage the clamp in the free state and to operate the clamp in the operable state to close the jaws. The applier has a housing disposed at a proximal end and a tube extending distally and configured to receive the clamp in the operable state. A shaft is disposed within the tube and movable between an extended position to engage the clamp in the free state and a retracted position to releasibly hold the clamp in the operable state. With the clamp in the operable state, the shaft is rotatable by operation of a handle and aladdin screw, to alternatively rotate in opposite directions to open and close the jaws of the clamp.
