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.

[ What is claimed is:] [1.] A surgical instrument handle for use with an elongate surgical instrument head, the surgical instrument head having a proximal end, a distal end forward of the proximal end and insertable into a patient, a head static part at the proximal end attachable to the surgical instrument, a reciprocative part generally at the proximal end, and a moveable distal part at the distal end, the moveable distal part being moveable relative to the head static part between a first position and a second position for enabling a surgeon to perform a surgical procedure on the patient, the reciprocative part being reciprocally moveable relative to the head static part generally along an instrument axis X between a forward position and a rearward position, said reciprocative part being operatively connected to said moveable distal part so that movement of the reciprocative part between its forward and rearward positions causes movement of the moveable distal part between its first and second positions, the surgical instrument handle comprising:a handle body comprising a handle stationary part and a handle rotor rotatably connected to the handle stationary part for rotation about the instrument axis X, the handle rotor being configured for fixedly receiving the head static part of the surgical instrument head so that rotation of the handle rotor relative to the handle stationary part causes like rotation of the surgical instrument head when the head static part is attached to the handle rotor;a handle plunger configured for reciprocating motion relative to the handle body generally along the instrument axis X between forward and rearward positions, the handle plunger being operatively engageable with the reciprocative part of the surgical instrument head when the head static part is attached to the handle body, the handle plunger being configured so that movement of the handle plunger between its forward and rearward positions causes movement of the reciprocative part of the surgical instrument head between its forward and rearward positions; andat least one lever arm connected to the handle body for lateral movement thereof relative to the handle axis between inward and outward positions, said at least one lever arm being configured for being engaged and laterally reciprocated between its inward and outward positions by a hand of a surgeon, said at least one lever arm being operatively connected to the handle plunger for moving the handle plunger between its forward and rearward positions as said at least one lever arm is moved between its inward and outward positions;said surgical instrument handle being configured so that said lateral movement of said at least one lever arm is in a plane spaced below the handle plunger to provide a forward line of sight generally along the instrument axis X to the distal end of the surgical instrument head as viewed from behind the handle plunger for permitting the surgeon's hand to move said at least one lever arm between its inward and outward positions without blocking the line of sight.
