Method and adaptor for connecting a powered surgical instrument to a medical console

A brush-to-brushless motor controller adapter for use with a two-wire output signal from a medical console consists of a small enclosure containing a circuit board and has a short cable terminating in a two-wire connector which plugs into the two-wire controller output of the medical console and a connector jack for an electrical connection to a surgical instrument having a brushless D.C. motor. The brush-to-brushless motor controller generates a stable voltage for the adapter internal electronics (i.e., 12 to 15 volts), from a varying input voltage (i.e., 2.5 to 30 volts D.C.). The surgical instrument brushless D.C. motor speed is controlled as a function of the console output signal drive voltage amplitude and the adapter accepts pulsed inputs from a high power two-wire motor controller (e.g., 10 watts and up). The adapter accepts bipolar drive signals and is adapted to reverse the surgical instrument brushless D.C. motor direction in response to a change in input voltage polarity from the two-wire medical console controller circuit. The adapter circuit of the present invention eliminates the need for a negative supply voltage by creating a positive bias in the control loop such that the control signal is nominally 2.5V above ground (i.e., zero volts) and the adapter internal positive voltage supply level. The adapter may be calibrated to provide a given top motor speed for different consoles by adjusting speed gain and speed offset voltages and so can work with consoles having different maximum speed voltage signals. The instrument including the brushless D.C. motor is preferably, but not necessarily, a surgical instrument such as a shaver or resector and may be used in conjunction with ancillary equipment such as a selectively switchable pump.
