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.

Abstract: A microsurgical instrument is comprised of a handle and a plurality of interchangeable instrument heads. Each of the instrument heads is constructed to perform a microsurgical operation such as forcep clamping and scissors cutting in a plane parallel to a longitudinal axis of the instrument, and in a plane positioned at an angle relative to the longitudinal axis of the instrument. The instrument handle is comprised of an exterior surface formed as at least two lever arms that are manually manipulable laterally toward and away from the longitudinal axis of the instrument to control the surgical operation performed by the instrument head connected with the handle. Because the entire handle exterior surface is manipulated to operate the instrument head connected with the handle, the instrument need not be held at any specific orientation relative to the hand in order to easily operate the instrument head by manipulating the fingers of the hand.

Abstract: A surgical instrument for use in penetrating and working in the vitreous humor of an eye comprises a finger grip member and a rigid needle extending from the finger grip member, with a single continuous fiber optic member extending from a distal end of the needle through the needle and the finger grip member to a cone shaped proximal end contained in a large connecting member constructed of heat conductive material. The surgical instrument includes a stripping tool at its distal end that is bent at a right angle and positioned in a plane that is parallel to the longitudinal axis of the needle but does not intersect this axis. The surgical instrument also comprises an infusion/aspiration system including a hollow pipe attached to the needle that extends parallel to the longitudinal axis of the needle but does not interfere with a beam of light projected from the distal end of the fiber optic member extending through the needle.
