  • Device for driving tools used in orthopedic surgery
    Patent number: 4834092
    Abstract: An air motor driven device adapted for driving tools used during orthopedic surgery by rotating a driven shaft on the tool. The device has first and second spaced parallel output shafts driven at different speeds, at least one of which shafts can releasably engage the driven shaft of the tool. The second shaft has a through central opening accessible from its end opposite its output end so that the device can power pin or wire drivers or reamers guided on a guide wire. An attachment mechanism for releasably attaching a tool to the device is provided which receives an oval portion of the tool in a mating socket, and in addition to trigger operated valves for operating the air motor, provides a valve for shutting off or throttling the gas inlet line.
    Type: Grant
    Filed: November 9, 1987
    Date of Patent: May 30, 1989
    Assignee: Minnesota Mining and Manufacturing Company
    Inventors: Charles E. Alexson, Heinz H. Guenther
