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.
[ What is claimed is:] [1.] A surgical instrument for use in endoscopy comprising:a tubular barrel with no joints and having a proximal end and a distal end;an end effector comprising a first working piece and a second working piece, each working piece being pivotally attached directly to the distal
[ What is claimed is:] [1.] A surgical instrument for use in endoscopy comprising:a tubular barrel with no joints and having a proximal end and a distal end;an end effector comprising a first working piece and a second working piece, each working piece being pivotally attached directly to the distal end of the tubular barrel, the two working pieces forming an operating angle therebetween;a handle attached to the proximal end of the tubular barrel, the handle comprising:an elongated stationary portion permanently fixed in alignment with the longitudinal axis of the tubular barrel, the stationary portion having a grip portion that is grippable by a single hand, wherein the stationary portion has a longitudinal axis that extends at an angle relative to the longitudinal axis of the tubular barrel;a manually operated actuating control; anda manually operated pivot control, the actuating and pivot controls being operable by the same hand which grips the grip portion; andlinkage extending through the tubular barrel, the linkage operably connecting the actuating control and the pivot control to the first and second end effector working pieces, whereinin response to the actuating control being operated, the linkage acts on the end effector to alter the operating angle; andin response to the pivot control being operated, the linkage acts upon both the first and second end effector working pieces to pivot the end effector working pieces simultaneously and in the same direction while maintaining a substantially constant operating angle.
