A surgical device includes a handle assembly having a controller and a motor. The surgical device also includes an adapter assembly having: a tubular housing having a proximal end portion configured to couple to the handle assembly and a distal end portion; and an actuation assembly configured to couple to the motor. The surgical further includes a reload configured to couple to the distal end portion of the adapter assembly; and an anvil assembly including an anvil head pivotally coupled to an anvil shaft, the anvil assembly configured to couple to the actuation assembly and the reload. The controller of the surgical device is configured to control the motor to actuate the actuation assembly to move the anvil assembly in a distal direction for a distance based on a dimension of one of the reload or the anvil head, thereby pivoting the anvil head relative to the anvil shaft while maintaining engagement of the anvil assembly to the reload.
