Surgical device

摘要

A surgical device includes a shaft portion coupled to a handle, the handle defining a longitudinal axis. The surgical device also includes a first driver configured to actuate a rotational movement via a first drive shaft and a second driver configured to actuate an articulation movement via a second drive shaft. The surgical device also includes a controller having a first dial and a second dial, the first dial actuated by the first driver and the second dial actuated by the second driver, the second dial positioned within the first dial.

1. A surgical device, comprising:
a handle; a shaft portion operatively coupled to the handle and defining a shaft longitudinal axis; an end effector operatively connected to the handle via the shaft portion; a first drive shaft operatively connected to the end effector; a second drive shaft operatively connected to the end effector; and a controller supported on the handle and including:
a first rotation wheel;a second rotation wheel nested with the first rotation wheel;a first sensor disposed adjacent the first rotation wheel; anda plurality of circumferentially-spaced sensed elements disposed around the first rotation wheel;the first rotation wheel 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;the second rotation wheel 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;the plurality of circumferentially-spaced sensed elements being configured to be sensed by the first sensor such that the first sensor effectuates the rotation of the first drive shaft upon a threshold amount of rotation of the first rotation wheel relative to the first sensor; andwherein the first sensor is a hall-effect sensor and the plurality of sensed elements are magnets.
