ABSTRACT:
This invention provides an improved surgical instrument, namely sponger-dissector forceps particularly adapted for laparoscopic intra-abdominal surgery such as gall bladder removal. Thus, sponges are retained locked in place without manual force upon the distal end of a substantially cylindrical hand held assembly by means of an internally mounted ratchet mechanism. In one embodiment sponges are retained by a 7 shaped distal end on a reciprocating 2 mm diameter rod disposed in a 10 mm diameter cylindrical housing member. The ratchet locks the reciprocating rod in place against movement in the distal direction, and thus holds sponges clamped in place at the distal end. The ratchet lock is releasable by a catch release button. The rod is manually reciprocated to engage and clamp a sponge by a finger operated slide member. The sponge is thus firmly held in position for blunt manipulation including direct hemostasis pressure on small blood vessels or for sponging to keep the surgical region dry. A clamping jaw embodiment provides for holding a sponge or alternatively for using the instrument for dissection or as a blood vessel clamp. Thus, tissue in an abdominal cavity may be grasped, displaced, or removed by manual manipulation from outside the body.
