Passive identification for limited-use surgical devices and limited-use disposable attachments

1 . A surgical system for a cutting device, comprising:

an integrated power console (IPC) configured to power a motor of a cutting device and monitor feedback from at least one indicator during use over time to indicate the condition of the motor, the IPC including a database of disposable cutting tools and associated operating and safety parameters;

and

a disposable cutting tool operably connected to the IPC, the disposable cutting tool including an elongated shaft operably engageable within the cutting device and supporting a cutting head at a distal end thereof such that rotation of the elongated shaft and the cutting head cuts tissue or bone, the disposable cutting tool including:

a shaft assembly configured to operably engage and selectively lock the disposable cutting tool onto the cutting device;

a proximal connector configured to operably align and engage the elongated shaft of the disposable cutting tool with an output shaft of the motor; and

an annular coupling disposed within the shaft assembly and configured to operably engage the shaft assembly and the proximal connector, at least a portion of an inner peripheral surface of the coupling made from a material configured to contact the elongated shaft such that upon engagement of the disposable cutting tool with the cutting device and during initialization, the IPC transmits and receives one or more electricals signals from the elongated shaft enabling the IPC to identify the disposable cutting tool from the database of disposable cutting tools and configure the associated operating and safety parameters particular to the disposable cutting tool,

wherein a contact geometry of the inner peripheral surface of the coupling varies to create a unique electrical ID for each disposable cutting tool.

2 . The surgical system according to claim 1 , wherein the amount of material in contact with the elongated shaft varies to create the unique electrical ID for each disposable cutting tool.

3 . The surgical system according to claim 1 , wherein the type of material in contact with the elongated shaft varies to create the unique electrical ID for each disposable cutting tool.

4 . The surgical system according to claim 1 , wherein the contact geometry of the inner peripheral surface of the coupling includes a series of annular rings configured to create the unique electrical ID for each disposable cutting tool.

5 . The surgical system according to claim 1 , wherein the contact geometry of the inner peripheral surface of the coupling includes one or more flanges that extend along the coupling parallel to the elongated shaft to create the unique electrical ID for each disposable cutting tool.

6 . The surgical system according to claim 5 , wherein the one or more flanges comprises a plurality of flanges arranged 90° relative to one another.

7 . A surgical system for a cutting device, comprising:

a disposable cutting tool including an elongated shaft having a proximal portion configured to operably engage the cutting device, the disposable cutting tool operably supporting a cutting head at a distal end thereof such that rotation of the elongated shaft and the cutting head cuts tissue or bone, the disposable cutting tool operably connected to an integrated power console (IPC) configured to power a motor to rotate the elongated shaft upon activation thereof and configured to monitor a condition of the motor via the elongated shaft, the IPC including a database of disposable cutting tools and associated operating and safety parameters, the proximal portion of the elongated shaft including a first geometric cross section, and the disposable cutting tool including:

a shaft assembly configured to operably engage and selectively lock the disposable cutting tool onto the cutting device;

a proximal connector configured to operably align and engage the elongated shaft of the disposable cutting tool with an output shaft of the motor; and

an annular coupling disposed within the shaft assembly and configured to operably engage the shaft assembly and the proximal connector, at least a portion of an inner peripheral surface of the coupling including a second geometric cross section configured to complement and slidingly receive the first geometric cross section therein, such that upon engagement of the disposable cutting tool with the cutting device and during initialization, the IPC transmits and receives one or more electrical signals from the elongated shaft enabling the IPC to identify the disposable cutting tool from the database of disposable cutting tools and configure the associated operating and safety parameters particular to the disposable cutting tool.

8 . The surgical system for a cutting device of claim 7 , wherein the second geometric cross section of the coupling engages the first geometric cross section of the shaft in a fluid-tight sealing relation therewith.

9 . The surgical system for a cutting device of claim 7 , wherein a contact geometry of the inner peripheral surface of the coupling includes a series of annular rings.

10 . The surgical system for a cutting device of claim 7 , wherein a contact geometry of the inner peripheral surface of the coupling includes one or more flanges that extend along the coupling parallel to the elongated shaft.

11 . The surgical system for a cutting device of claim 10 , wherein the one or more flanges comprises a plurality of flanges arranged 90° relative to one another.
