| 摘要 |
The present invention is directed toward an external drive with a plurality of removably mounted disposable surgical hand cutting assemblies including a housing control unit with a plurality of motors, each of the motors being capable of driving each surgical hand cutting assembly at a different range of rotational speeds. One disposable surgical hand cutting assembly is capable of debriding soft tissue at a first speed and high torque, and a second disposable hand cutting assembly is capable of debriding hard tissue at a second higher speed. A plurality of flexible shafts for transmitting the torsional force from a selected motor to a selected surgical hand cutting assembly provided with a quick connect mechanism disposed on the end of each flexible shaft to quickly connect the surgical hand cutting assembly to one of the motors.
