Abstract
A surgical stapling device includes a staple reload and a handle assembly that supports a drive rack, a motor assembly, a gear assembly, a reload select mechanism, and a safety toggle mechanism. The gear assembly is adapted to facilitate uncoupling of the motor assembly from the drive rack to allow manual movement of the drive rack. The reload select mechanism allows the length of a stroke of the drive rack to be selectively adjusted to allow the stapling device to accommodate different length staple reloads. The safety toggle mechanism is provided to move the stapling device from a non-firing state to a firing state to allow for firing of the stapling device.
