Abstract
A powered handle for a surgical stapler can have a drive system including an electric motor. The powered handle can include a manual return mechanism. The powered handle can also include a retention mechanism to prevent unintentional movement of drivetrain components upon actuation of the manual return mechanism. For example, the retention mechanism can apply a direction-dependent frictional force on an actuation shaft of the handle assembly to prevent unintentional movement of the actuation shaft towards a distal end of the handle assembly. The retention mechanism can include a featherboard-like configuration with a plurality of ribs oriented transversely to the actuation shaft to restrict movement of the actuation shaft in one direction while allowing movement of the shaft in the opposite direction.
