Designed for use in (but not limited to) laparoscopic surgery, this surgical instrument actuator (10) is a user-friendly handle (16) that contains operating means (20) which convert rotary input motion from a thumb operated input lever (20) to linear motion which is transmitted by means of an actuator rod (14) to the distal end (18) of the instrument (10) where the motion is used to operate various types of instrument tip assemblies (18) such as jaws, cutters, hooks, scissors, etc. The handle (16) is designed for right or left hand operation with minimum fatigue, and other features included are free rotation of the instrument tip(s) (18) about the axis of the main instrument shaft (12) a transitional lock system (58), accommodations for electric cautery (30), and a flushing system (108) for removing body fluids that leak into the main shaft tube (12) during surgery. |
