Patent ID: 8480703

Claim:
A surgical device, comprising: a handle; a shaft portion coupled to the handle, the shaft portion defining a shaft longitudinal axis; an end effector supported on a distal end of the shaft portion so as to rotate and pivot relative to the shaft portion; a first drive shaft extending through the shaft portion and operatively connected to the end effector; a second drive shaft extending through the shaft portion and operatively connected to the end effector; and a controller supported on the handle so as to be actuated by a thumb of a hand of an operator holding the handle with a single hand in a pistol-grip fashion, the controller including: a first rotatable member; and a second rotatable member; the first rotatable member being configured to rotate the first drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction rotation and second direction rotation of the end effector relative to the shaft portion; and the second rotatable member being configured to rotate the second drive shaft in one of a first direction and a second direction upon a corresponding first direction and second direction rotation thereof to effectuate a corresponding first direction pivoting and second direction pivoting of the end effector relative to the shaft portion; wherein the controller includes: a first Hall-Effect switch associated with the first rotatable member for effectuating, the rotation of the first drive shaft; and a second Hall-Effect switch associated with the second rotatable member for effectuating the rotation of the second drive shaft.
