Claim 0:
1. A surgical clamp comprising:
a two-piece body comprising a top jaw housing that inter-fits with a bottom jaw housing;
the top jaw housing comprising a top jaw and a top wall, the top wall comprising an open slot through which a lever extends to contact a rack;
the bottom jaw housing comprising a bottom jaw, a bottom wall, and a bottom base, the bottom base comprising a shoulder;
the inter-fitting top jaw housing and bottom jaw housing disposed for movement relative to one another, the top wall and the bottom wall moving along each other's length in a telescopic movement delimited by a top wall upper surface abutting the shoulder;
a bias to separate the top jaw housing and bottom jaw housing apart and to urge the top jaw and the bottom jaw apart; and
the lever moveable between a lock position and an open position and the lever disposed to prevent opening movement of the top jaw housing relative to the bottom jaw housing and to allow graduated relative closing movement of the top jaw housing relative to the bottom jaw housing in the lock position and to allow opening and closing movement of the top jaw housing relative to the bottom jaw housing in the open position;
wherein the lever comprises an axial arm and a lateral arm, the axial arm extending in a direction between the top jaw housing and the bottom jaw housing, the lateral arm extending in a direction of the top jaw and the bottom jaw, wherein the axial arm comprises one or more tooth or pawl disposed at a distal end of the axial arm and the lateral arm comprises a button disposed on a distal end of the lateral arm, wherein the one or more tooth or pawl is disposed on a jaw side of the surgical clamp to extend through the open slot to thereby contact the rack and the button is disposed on an opposite side of the surgical clamp;
wherein the lever comprises an integral component comprising the lateral arm and the axial arm and the button in one piece, wherein pressing the button or the distal end of the lateral arm obliquely pivots or moves the axial arm out of the open slot and disengages the one or more tooth or pawl from the rack;
wherein the button comprises a region of the lever of increased width to assist in applying a force required to pivot or move the lever; and
wherein the lever comprises a top bias retaining surface and the bottom jaw housing comprises a bottom bias retaining surface to retain the bias therebetween;
such that compressive force applied to one or more of the top jaw housing and the bottom jaw housing causes graduated closing movement of the top jaw housing and the bottom jaw housing to close the top jaw and the bottom jaw.
