BACKGROUND

In some settings, endoscopic surgical instruments may be preferred over traditional open surgical instruments since a smaller incision may reduce the post-operative recovery time and complications. Consequently, some endoscopic surgical instruments may be suitable for placement of a distal end effector at a desired surgical site through a cannula of a trocar. These distal end effectors may engage tissue in a number of ways to achieve a diagnostic or therapeutic effect (e.g., endocutter, grasper, cutter, stapler, clip applier, access device, drug/gene therapy delivery device, and energy delivery device using ultrasound, RF, laser, etc.). Endoscopic surgical instruments may include a shaft between the end effector and a handle portion, which is manipulated by the clinician. Such a shaft may enable insertion to a desired depth and rotation about the longitudinal axis of the shaft, thereby facilitating positioning of the end effector within the patient.
Examples of endoscopic surgical instruments include those disclosed in U.S. Pat. Pub.

Control module (12) and power source (14) are coupled by an electrical connection (22), such as a cable and/or traces in a circuit board, etc., to transfer power from power source (14) to control module (12). Alternatively, power source (14) may be selectively coupled to control module (12). This allows power source (14) to be detached and removed from medical device (10), which may further allow power source (14) to be readily recharged or reclaimed for resterilization and reuse, such as in accordance with the various teachings herein. In addition or in the alternative, control module (12) may be removed for servicing, testing, replacement, or any other purpose as will be apparent to one of ordinary skill in the art in view of the teachings herein.
End effector (16) is coupled to control module (12) by another electrical connection (22). End effector (16) is configured to perform a desired function of medical device (10). By way of example only, such function may include cauterizing tissue, ablating tissue, severing tissue, ultrasonically vibrating, stapling tissue, or any other desired task for medical device (10). End effector (16) may thus include an active feature such as an ultrasonic blade, a pair of clamping jaws, a sharp knife, a staple driving assembly, a monopolar RF electrode, a pair of bipolar RF electrodes, a thermal heating element, and/or various other components. End effector (16) may also be removable from medical device (10) for servicing, testing, replacement, or any other purpose as will be apparent to one of ordinary skill in the art in view of the teachings herein. In some versions, end effector (16) is modular such that medical device (10) may be used with different kinds of end effectors (e.g., as taught in U.S. Provisional Application Ser.
