Surgical instrument including a locking assembly
First Claim
1. A 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, the articulating tool assembly being 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 to the first longitudinal axis; and
a locking assembly including a pusher in mechanical cooperation with the body portion and a pivot in mechanical cooperation with the articulating tool assembly, the pusher having a pusher mating surface dimensioned to mate with a pivot mating surface of the pivot, the pusher being distally biased towards the pivot and forced proximally as the articulating tool assembly is move to the second position.

Abstract
A surgical instrument including a handle portion, a body portion, an articulating tool assembly and a locking assembly is disclosed. The body portion extends distally from the handle portion and defines a first longitudinal axis. The articulating tool assembly defines a second longitudinal axis and is movable from a first position where the second longitudinal axis is substantially aligned with the first longitudinal axis to at least a second position where the second longitudinal axis is at an angle to the first longitudinal axis. The locking assembly includes a pusher in mechanical cooperation with the body portion and a pivot in mechanical cooperation with the articulating tool assembly. The pusher includes a mating surface dimensioned to mate with a pivot mating surface. The pusher is distally biased towards the pivot and is forced proximally as the articulating tool assembly is moved to the second position.

10. A disposable loading unit configured for releasable engagement with a surgical instrument, comprising:
-
a body portion defining a first longitudinal axis; an articulating tool assembly disposed distally of the body portion being securable to a distal end of the body portion and defining a second longitudinal axis, the articulating tool assembly being movable from a first position in which the second longitudinal axis is substantially aligned with the first longitudinal axis to a second position in which the second longitudinal axis is disposed at an angle to the first longitudinal axis; and a locking assembly including a pusher in mechanical cooperation with the body portion and a pivot in mechanical cooperation with the articulating tool assembly, the pusher having a pusher mating surface dimensioned to mate with a pivot mating surface of the pivot, the pusher being distally biased towards the pivot and forced proximally as the articulating tool assembly is moved to the second position. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
