Surgical instrument handle with adjustable actuator position

摘要

A surgical instrument handle operates a microsurgical instrument on a surgical instrument head by manipulation of the instrument handle. The instrument handle has an elongate center rod with a ring mounted on the rod for reciprocating movement. The ring is operatively associated with the surgical instrument head for operation of the microsurgical instrument of the head. A plurality of resilient arms extend along the length of the rod and engage against a sliding surface of the ring. The inward and outward movement of the plurality of arms reciprocates the ring on the handle rod to cause operation of the surgical instrument head.

主权项

1. A surgical instrument handle comprising:
an elongate rod having a center axis that defines mutually perpendicular axial and radial directions, the rod having a length with axially opposite proximal and distal ends; a ring mounted on the rod adjacent the rod distal end for axially reciprocating sliding movement of the ring over the rod toward and away from the rod distal end; a forward grip member connected to the rod proximal end, the forward grip member having a plurality of resilient arms that extend axially from the rod proximal end along the rod to distal ends of the arms that are circumferentially arranged around and in sliding engagement with the ring whereby manual movement of the arm distal ends radially inwardly moves the ring axially toward the rod distal end and movement of the ring axially away from the rod distal end moves the arm distal ends radially outwardly; the ring having a distal end face that faces toward the rod distal end and the ring having a proximal end face that faces toward the rod proximal end, the ring proximal end face being formed as a sliding surface; and the distal ends of the forward grip member arms engaging in sliding engagement with the ring sliding surface.
