Classification: CPC A | IPC A

Claim 12:
13. A medical device comprising:
a shaft including a distal end and a proximal end;
an end effector at the distal end of the shaft; and
a handle at the proximal end of the shaft, wherein the handle includes:
a first actuator that is movable in a first direction relative to the handle, wherein the first actuator is configured to actuate an actuator wire coupled to the end effector, wherein the end effector is actuated in response to moving the first actuator in the first direction;
a second actuator that is movable in a second direction relative to the handle, wherein, in response to moving the second actuator in the second direction, the second actuator is configured translate a first drive wire and a second drive wire longitudinally to deflect the end effector relative to the shaft; and
a third actuator that is movable in a third direction relative to the handle, wherein the third actuator is configured to rotate the actuator wire coupled to the end effector, wherein the end effector is rotated relative to the shaft in response to moving the third actuator in the third direction;

wherein the first direction is parallel to a longitudinal axis of the shaft, and the third direction is about the longitudinal axis of the handle,
wherein the first drive wire extends around the third actuator on a first side of the handle, wherein the second drive wire extends around the third actuator on a second side of the handle, and wherein the second side of the handle is opposite the first side of the handle.
