Articulating powered surgical instruments

摘要

A surgical instrument includes a handle portion and a body portion extending distally from the handle portion and defining a first longitudinal axis. The surgical instrument includes an articulating tool assembly defining a second longitudinal axis and having a proximal end. The articulating tool assembly is disposed at a distal end of the body portion and is configured to be articulated with respect to the body portion, namely, the articulating tool assembly is movable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position in which the second longitudinal axis is disposed at an angle with respect to the first longitudinal axis. The surgical instrument also includes an articulation mechanism configured to articulate the articulating tool assembly.

1. A powered surgical instrument comprising:
a handle portion; a body portion extending distally from the handle portion and defining a first longitudinal axis; an articulating tool assembly defining a second longitudinal axis and having a proximal end, the articulating tool assembly disposed at a distal end of the body portion and being movable from a first position in which the second longitudinal axis is aligned with the first longitudinal axis to at least a second position in which the second longitudinal axis is disposed at an angle with respect to the first longitudinal axis; and an articulation mechanism configured to articulate the articulating tool assembly, wherein the articulation mechanism includes:
a motor operatively coupled to the articulating tool assembly;a controller electrically coupled to the motor and configured to control operation of the motor; anda first switch and a second switch, the first and second switches being coupled to the controller, wherein a rotation of the first switch and the second switch in a same rotational direction signals the controller to activate the articulation mechanism.
