Abstract
A powered or robotic surgical stapler includes a loading unit having an end effector with an anvil and staple cartridge. A drive shaft disposed in the loading unit is actuated by one or more motors. The drive shaft approximates the anvil and advances a knife and a sled to eject a plurality of staples from the cartridge. A position sensor and a torque or current draw sensor measure operation of the motor and a processor determines an initial peak in the torque or current. The processor then calculates a stop position from the drive shaft based on a motor position corresponding to the initial peak and actuates the drive shaft until it reaches the stop position, which occurs prior to the drive shaft reaching a mechanical limit of the drive shaft.
