ABSTRACT:
A surgical instrument comprises an instrument head and an instrument handle. The instrument head has a proximal end, a distal end, a head static part at the proximal end, a reciprocative part generally at the proximal end, and a moveable distal part at the distal end. The reciprocative part is operatively connected to the moveable distal part so that movement of the reciprocative part between forward and rearward positions causes movement of the moveable distal part between first and second positions. The instrument handle has a handle body attachable to the head static part of the instrument head, a handle plunger configured for reciprocating relative to the handle body generally along the instrument axis, and a lever arm. The handle plunger is operatively engageable with the reciprocative part of the instrument head when the head static part is attached to the handle body. Movement of the handle plunger between forward and rearward positions causes movement of the reciprocative part of the instrument head between its forward and rearward positions. The lever arm is connected to the handle body is engaged and laterally reciprocated by a hand of a surgeon. It is operatively connected to the handle plunger for moving the handle plunger between its forward and rearward positions as the lever arm is moved between inward and outward positions. The instrument handle is configured so that the lateral movement of the lever arm is in a plane spaced below the handle plunger to provide a forward line of sight generally along the instrument axis to the distal end of the instrument head as viewed from behind the handle plunger for permitting the surgeon's hand to reciprocate the lever arm without blocking the line of sight.
