摘要

A powered surgical tool system including a tool unit (124} and a battery and control module (128). The battery and control module includes: cells (38) for supplying a charging current; sensors for monitoring a switch and/or the state of the tool power generating unit; and a controller (530) that, based on the signals from the sensors, selectively sources energization signals to the power generating unit (950) internal to the tool.
