Abstract:
An air motor (21) driven device (10) adapted for driving tools (11, 12, 13, 14) used during orthopedic surgery by rotating a driven shaft (16, 17, 18, 19) on the tool. The device (10) has first and second spaced parallel output shafts (23, 24) driven at different speeds, at least one of which shafts (23, 24) can releasably engage the driven shaft (16, 17, 18, 19) of the tool (11, 12, 13, 14). The second shaft (24) has a through central opening (28) accessible from its end (29) opposite its output end (26) so that the device (10) can power pin or wire drivers or reamers guided on a guide wire. An attachment mechanism for releasably attaching a tool (11, 12, 13, 14) to the device (10) is provided which receives an oval portion (46, 47, 48, 49) of the tool (11, 12, 13, 14) in a mating socket (45), and in addition to trigger (84) operated valves (97) for operating the air motor (21), provides a valve (99) for shutting off or throttling the gas inlet line (80).
