Abstract

An endoscopic surgical instrument with manual controls and single-handed design has a tubular barrel with a handle at its proximal end and an end effector at its distal end. A linkage extends through the tubular barrel and connects the handle with the end effector. The handle has a stationary finger loop, in fixed alignment with the longitudinal axis of the tubular barrel, and is designed to receive a middle finger. The handle also includes a thumb lever, a fingerwheel control and a rotate control. The thumb lever, operated by the thumb of the hand gripping the finger loop, actuates the end effector; the fingerwheel control, operated by the index finger of the hand gripping the finger loop, pivots the end effector; and the rotate control, which is also actuated by the same index finger, rotates the tubular barrel and attached end effector. The endoscopic surgical instrument may also be configured to include electrocautery capability, an integrated endoscope, and irrigation and aspiration capabilities is also disclosed.
