Surgical scissors are provided having two scissor blades mounted for pivotal movement relative to each other about a pivot axis and having one cutting edge each. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention. The electronic module is mounted to at least one of the lens module and the image sensor module. A substantial performance gain is attained compared to microprocessor controlled format converters. The controller enables the high voltage control system to cooperate with motor, therefore a user is not necessary to design a new high voltage control system when replacing the conventional AC motor with the DC brushless motor, which saves time, and reduces cost. The internal power source voltage generating circuit configured to generate a first internal power source voltage is applied to the first functional integrated circuit and a second internal power source voltage is applied to the second functional integrated circuit.
