1. A handle assembly for a surgical device comprising:
a stationary body including a proximal portion and a distal portion and defining a cavity, the distal and proximal portions of the stationary body each defining an opening, the stationary body having an outer gripping surface;
a distal body portion extending distally from the stationary body through the opening in the distal portion of the stationary body, the distal body portion defining a longitudinal axis, the gripping surface of the stationary body positioned about the longitudinal axis;
a firing rod assembly including a firing rod extending within the distal body portion and a drive rod, the drive rod supported within the cavity of the stationary body and having a distal portion coupled to the firing rod and a proximal portion;
a motor including a drive shaft supported within the cavity of the stationary body, the motor coupled to the drive rod and being operable to move the drive rod between a retracted position and an advanced position, wherein movement of the drive rod between its retracted and advanced positions moves the firing rod between retracted and advanced positions;
a release member attached to the proximal portion of the drive rod and extending from a proximal-most end of the proximal portion of the stationary body; and
a battery cover supported on the proximal portion of the stationary body and movable between an open position and a closed position, the battery cover defining a cavity, the release member extending into the cavity defined by the battery cover when the battery cover is in the closed position and being accessible when the battery cover is in its open position.
