Endoscopic Device
First Claim
1. An endoscopic surgical instrument for performing a surgical procedure inside a patient, said instrument comprising:
- a handle assembly including a grip for holding the instrument and a plurality of controls for controlling movement of the instrument;
an elongate shaft having a grip end mounted on the handle assembly and a working end opposite said grip end, said shaft having a proximal portion adjacent said grip end and a distal portion adjacent said working end, said proximal portion having a centerline and being selectively rotatable with respect to the handle assembly about the centerline of the proximal portion of the shaft, said distal portion having a centerline and being selectively articulatable relative to the centerline of the proximal portion of the shaft; and
an end effector mounted on the working end of the elongate shaft, said end effector being selectively rotatable about the centerline of the distal portion of the shaft.

Abstract
An endoscopic surgical instrument for performing a procedure inside a patient. The instrument includes a handle assembly including a grip for holding the instrument and controls for controlling movement of the instrument. An elongate shaft having a grip end is mounted on the handle assembly. The shaft has a working end opposite the grip end. The shaft has a proximal portion adjacent the grip end and a distal portion adjacent the working end. The proximal portion has a centerline and is selectively rotatable with respect to the handle assembly. The distal portion has a centerline and is selectively articulatable relative to the proximal portion of the shaft. The instrument includes an end effector mounted on the working end of the elongate shaft. The end effector is selectively rotatable about the distal portion of the shaft.
