ABSTRACT:
A surgical clamp includes a first jaw having a proximal end and a distal end, and a pawl secured to the first jaw near the proximal end. The pawl is biased in a proximal direction via a leaf spring. The surgical clamp further includes a second jaw having a proximal end and a distal end. The second jaw is adapted for being pivotally secured to the first jaw, and includes a ratchet disposed proximally relative to the pawl and in mesh with the pawl when the second jaw is secured to the first jaw. The surgical clamp further includes a movable member secured to the first jaw, which is adapted for contacting and moving the pawl in a distal direction against the bias of a leaf spring to thereby move the pawl out of mesh with the ratchet. The first jaw and the second jaw are movable from a closed state to an open state when the pawl is moved in the distal direction by the movable member. The pawl is adapted to be biased back into mesh with the ratchet when the movable member is removed from contact with the pawl.
