Abstract

Disclosed is an instrument assembly usable in a procedure. The instrument includes a connection for a working portion and to a tool handle. The assembly includes a method and system for interconnection and/or identification of the working portion and the handle. The instrument may also include various trackable features to allow for a navigated procedure.

First claim

What is claimed is:

1. A system for connecting a tool assembly, comprising:
a handpiece, including:
a housing that is sized and shaped to be held by a hand of a user;
a motor within the housing;
a handpiece connector;

a cartridge member having:
a cartridge connector configured to engage the handpiece connector;
a first line extending from the cartridge member and operable to be connected to a console;
a second line extending from the cartridge member and operable to be connected to the console;

wherein the cartridge member is configured to be removably connected to the handpiece to connect the first line and the second line to the handpiece;
wherein at least the first line or the second line is an electrical power line;
wherein the cartridge member further includes an electrical connector;
wherein the electrical connector is operable to deliver electrical energy from the electrical power line to at least one of the handpiece or an instrument assembly connected to the handpiece;
wherein the electrical connector includes an antenna operable to wirelessly transfer power to at least one of the handpiece or the instrument assembly connected to the handpiece.

2. The system of claim 1 , wherein the engagement of the cartridge connector to the handpiece connector is operable to hold the cartridge member relative to the handpiece.

3. The system of claim 1 , further comprising:
the console, wherein the console is operable to provide operation features to the handpiece.

4. The system of claim 3 , wherein the first line is an irrigation line wherein an irrigation fluid is able to flow from an irrigation source through the irrigation line to an irrigation passage within the handpiece after the cartridge member is operably engaged with the handpiece.

5. A system for connecting a tool assembly, comprising:
a handpiece, including:
a housing that is sized and shaped to be held by a hand of a user;
a motor within the housing;
a handpiece connector;

a cartridge member having:
a cartridge connector configured to engage the handpiece connector;
a first line extending from the cartridge member and operable to be connected to a console;
a second line extending from the cartridge member and operable to be connected to the console;

wherein the cartridge member is configured to be removably connected to the handpiece to connect the first line and the second line to the handpiece;
wherein the first line is at least one of an irrigation line or a suction line;
wherein the second line is an electrical power line;
a first instrument assembly operable to be removably connected to the handpiece; and
a second instrument assembly operable to be removably connected to the handpiece separate from the first instrument assembly;
wherein the first instrument assembly is configured to be connected to the handpiece and in fluid communication with an irrigation source and a power source through the cartridge member;
wherein the second instrument assembly is configured to be connected to the handpiece and in fluid communication with the irrigation source and the power source through the cartridge member;
wherein the first instrument assembly is configured to be removed from the handpiece while the cartridge member remains connected to the handpiece and the second instrument assembly is connected to the handpiece while the cartridge member remains connected to the handpiece.

6. The system of claim 5 , wherein the first line is the suction line.

7. The system of claim 5 , wherein the cartridge member further includes an electrical connector;
wherein the electrical connector is operable to deliver electrical energy from the electrical power line to at least one of the handpiece, the first instrument assembly or the second instrument assembly connected to the handpiece.

8. The system of claim 7 , wherein the electrical connector includes an antenna operable to wirelessly transfer power to at least one of the handpiece, the first instrument assembly or the second instrument assembly connected to the handpiece.

9. The system of claim 5 , wherein the cartridge member further includes a receiver assembly;
wherein the receiver assembly is operable to receive a signal from at least one of an identification member associated with an instrument connected to the handpiece or a tracking device associated with the instrument connected to the handpiece.

10. The system of claim 9 , wherein the receiver assembly includes an antenna to wirelessly receive the signal from at least one of the identification member associated with the instrument connected to the handpiece and the tracking device associated with the instrument connected to the handpiece.

11. The system of claim 5 , wherein the cartridge member provides an only connection to the console from the handpiece and the first instrument assembly or the second instrument assembly.

12. The system of claim 11 , further comprising:
a first identification member and a first tracking device associated with the first instrument assembly;
a second identification member and a second tracking device associated with the second instrument assembly;
an antenna within the cartridge member configured to:
interrogate the first identification member and the second identification member and transmit a signal based on the interrogation; and
receive a tracking signal from the first tracking device and the second tracking device.

13. A system for connecting a tool assembly, comprising:
a handpiece, including:
a housing that is sized and shaped to be held by a hand of a user;
a motor within the housing;
a handpiece connector;

a cartridge member having:
a cartridge connector configured to engage the handpiece connector;
a first line extending from the cartridge member and operable to be connected to a console;
a second line extending from the cartridge member and operable to be connected to the console;

a first instrument assembly configured to be removably connected to the handpiece to be powered by the motor;
a first tracking device associated with the first instrument assembly configured to be connected to a surgical navigation system via the first line; and
an irrigation system connected to the second line;
wherein the cartridge member is configured to be removably connected to the handpiece to connect the first line and the second line to the handpiece.

14. The system of claim 13 , further comprising:
the surgical navigation system configured to track the first tracking device based on a signal from the first tracking device via the first line;
wherein the first line is further configured to deliver power to the tracking device.

15. The system of claim 14 , further comprising:
a second instrument assembly configured to be removably connected to the handpiece to be powered by the motor; and
a second tracking device associated with the second instrument assembly configured to be connected to the surgical navigation system via the first line;
wherein the first instrument assembly is configured to be removed from the handpiece while the cartridge member remains connected to the handpiece and the second instrument assembly is connected to the handpiece while the cartridge member remains connected to the handpiece.

16. The system of claim 15 , wherein the cartridge member is an only connection to the console from the handpiece.

17. A system for connecting a tool assembly, comprising:
a handpiece, including:
a housing that is sized and shaped to be held by a hand of a user;
a motor within the housing;
a first co
