Method And Adaptor For Connecting A Powered Surgical Instrument To A Medical Console

US Patent:
5903117, May 11, 1999
Filed:
Oct 28, 1997
Appl. No.:
8/959027
Inventors:
William W. Gregory - Jacksonville FL
Assignee:
Xomed Surgical Products, Inc. - Jacksonville FL
International Classification:
H02K23/00
US Classification:
318254
Abstract:
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.
