Safety Method For Powered Surgical Instruments
First Claim
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 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; 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; and
at least one switch coupled to the controller, wherein the at least one switch is configured to signal the controller to activate the articulation mechanism in response to the at least one switch being engaged for a predetermined period of time.

Abstract
The present disclosure provides for a surgical instrument. The 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.

13. An articulation mechanism configured to articulate an articulating tool assembly, the articulation mechanism comprising:
-
a motor operatively coupled to an articulating tool assembly; a controller electrically coupled to the motor and configured to control operation of the motor; and a first switch and a second switch coupled to the controller, wherein the controller activates the articulation mechanism in response to the first and second switches being concurrently engaged for a predetermined period of time. - View Dependent Claims (14, 15, 16, 17)
