Methods and devices for controlling motorized surgical devices

A surgical system, comprising:

• a handheld surgical device that includes a proximal handle portion and a distal end effector configured to engage tissue;
• a motor configured to provide an output that causes the distal end effector to move relative to the proximal handle portion;
• a wire extending outside the proximal handle portion and being configured to be selectively attached to and detached from the motor by being reattachable thereto;
• and
• a non-rechargeable power source attached to the wire at a location outside the proximal handle portion and being configured to provide power to the motor when the wire is attached to the motor, the power provided to the motor allowing the motor to provide the output;
• wherein the wire has a first end attached to the handheld surgical device and a second end configured to be selectively attached to and detached from the motor by being reattachable thereto, the power source being adjacent to the second end.

• a cutting element configured to move longitudinally through the distal end effector, the motor being configured to provide power that causes the movement of the cutting element;
• and
• a controller configured to, in response to the wire being attached to the motor, trigger sensing of an initial position of the cutting element.
