摘要：

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 (170) configured to articulate the articulating tool assembly, wherein the articulation mechanism (170) includes: a motor (132) operatively coupled to the articulating tool assembly; a controller (400) electrically coupled to the motor (132) and configured to control operation of the motor (132); and at least one switch (114) coupled to the controller (400), wherein the at least one switch (114) is configured to signal the controller (400) to activate the articulation mechanism in response to the at least one switch (114) being engaged for a predetermined period of time.
