Disposable remote flexible drive cutting apparatus

An external drive with a plurality of removably mounted disposable surgical hand cutting assemblies comprising:

• a housing control unit comprising a plurality of motors, each of said motors being capable of driving a selected removably mounted disposable surgical hand cutting assembly at a range of different rotational speeds;
• at least one disposable surgical hand cutting assembly being capable of debriding hard tissue at a first speed and a second disposable surgical hand cutting assembly being capable of debriding soft tissue at a second different speed;
• flexible shaft means for transmitting the torsional force from a selected motor to a selected disposable surgical hand cutting assembly;
• and,
• quick connect means disposed on the end of said flexible shaft means to quickly connect said selected disposable surgical hand cutting assembly to one of the motors of said plurality of motors.

An external drive with a plurality of selectively mounted disposable surgical handpiece assemblies for cutting tissue, comprising:

• a housing control unit comprising a plurality of motors, each of said motors being capable of driving a selected surgical handpiece assembly at a different range of rotational speeds;
• one of said selectively mounted disposable surgical handpiece assemblies being capable of debriding hard tissue with another of said surgical handpiece assemblies being capable of cutting soft tissue;
• flexible shaft means for transmitting the torsional force from a selected motor to a surgical handpiece included in each surgical handpiece assembly;
• and
• quick connect means disposed on an end of said flexible shaft means to quickly connect said surgical handpiece to a selected motor of said plurality of motors.

A surgical tissue cutting and debriding system, comprising:

• a motor control unit comprising a plurality of motors, each of said motors being adapted to operate in a different operating range of rotational speeds;
• control means for controlling the rotational speed and direction of a selected motor of said plurality of motors;
• a plurality of surgical hand cutter means comprising a first surgical hand assembly adapted to debride tissue at a first high range of rotational speeds and a second surgical hand assembly adapted to debride tissue at a second lower range of rotational speeds;
• and
• a plurality of flexible shaft assemblies, each shaft assembly of said plurality of shaft assemblies being selectively connected to a surgical hand assembly of said plurality of surgical hand assemblies for transmitting the rotational speed and direction of each motor shaft of said plurality of motors to each surgical hand assembly.
