Abstract
A surgical instrument including a handle portion, a body portion, an articulating tool assembly and at least one coupling member 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 has a proximal end including at least one recess therein. The articulating tool assembly is securable to a distal end of the body portion and is movable from a first position where the first and second longitudinal axes are substantially aligned to at least a second position where the first and second longitudinal axes are at an angle. The coupling member has at least one spring arm and is securable to the body portion. At least a portion of the spring arm is receivable in the recess of the articulating tool assembly to releasably retain the articulating tool assembly in the first position.
