Abstract
A surgical instrument handle is removably attachable to a surgical instrument head for operation of a microsurgical instrument on the head by manipulation of the instrument handle. The instrument handle has an elongate center rod with a piston mounted on the rod for reciprocating movement. The piston engages with a piston in the attached surgical instrument head for operation of the microsurgical instrument of the head. A tapered ring is mounted on the rod and engages with the piston for reciprocating the piston. A plurality of resilient arms extend along the length of the rod and engage against a sliding surface of the ring. The plurality of resilient arms are alternatively squeezed radially inwardly by the surgeon's hand and released by the surgeon's hand to allow the resilient arms to flex radially outwardly. The inward and outward movement of the plurality of arms reciprocates the piston on the handle rod to cause operation of the surgical instrument head. The radial position of the resilient arms relative to the handle is adjustable as desired by the surgeon.
