Abstract

Claims (47)

1. A system for operating an assembly, comprising:

an instrument assembly;

a handpiece having a longitudinal axis defined therealong, including:

a housing that is sized and shaped to be held by a hand of a user;

a motor within the housing;

a first connector configured to engage the instrument assembly for performing a procedure with at least a portion of the instrument assembly;

a second connector formed on the housing;

a cartridge member having a cartridge connector configured to engage and hold the cartridge member relative to the handpiece, the cartridge member having a plurality of internal components including an irrigation line, an irrigation outlet, and an antenna;

wherein the cartridge member is configured to be removably connected to the handpiece to connect the irrigation line to the handpiece;

wherein the instrument assembly includes an irrigation passage;

wherein an irrigation fluid is able to flow from an irrigation source through the irrigation passage of the instrument assembly after the cartridge member is connected to the handpiece;

wherein the instrument assembly includes a first instrument assembly and a second instrument assembly;

wherein the first instrument assembly is configured to be connected to the handpiece and in fluid communication with the irrigation 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 through the cartridge member;

wherein the first instrument assembly is configured to be removed from the handpiece while the cartridge member is connected to the handpiece and the second instrument assembly is connected to the handpiece while the cartridge member is connected to the handpiece, wherein the cartridge member includes a slideable connection that, upon engagement with the handpiece, registers a plurality of internal components of the handpiece along the longitudinal axis for transverse mechanical engagement to or transverse electrical communication with the corresponding plurality of internal components of the cartridge member.

2. The system of claim 1 , wherein the cartridge member is fixedly connected to the irrigation line.

3. The system of claim 2 , wherein the second connector includes a rail;

wherein the cartridge connector includes a groove;

wherein the rail has an exterior dimension that is received in the groove to connect the cartridge member to the handpiece.

4. The system of claim 1 , further comprising:

a first identification member associated with the first instrument assembly;

a second identification member associated with the second instrument assembly;

wherein the antenna within the cartridge member is configured to interrogate the first identification member and the second identification member and transmit a signal based on the interrogation;

wherein the signal is configured to allow determination of an identify of either the first instrument assembly or the second instrument assembly.

5. The system of claim 1 , wherein the cartridge member further includes a control member configured to receive an input from a user to change an operation of at least one of the motor, a flow from the irrigation source, or combinations thereof.

6. The system of claim 1 , wherein the cartridge member further includes an indicator configured to provide an output to indicate a current operation of at least one of the motor, a flow from the irrigation source, or combinations thereof.

7. The system of claim 1 , further comprising a first sealing assembly disposed about the irrigation line on the cartridge member and a complimentary second sealing assembly disposed about an irrigation inlet of the handpiece, wherein the first and second sealing assemblies form a fluid tight seal upon sliding longitudinal registration and mechanical engagement of the cartridge member with the handpiece.

8. The system of claim 7 , wherein the first and second instrument assemblies include an integrated hub assembly and wherein the complimentary sealing assemblies provide fluid tight irrigation between the cartridge and the handpiece upon longitudinal registration and mechanical engagement therewith without manipulation of the integrated hub assembly separate from placing the instrument assembly onto the handpiece.

9. A system for operating an assembly, comprising:

an instrument assembly having an irrigation passage;

a handpiece, including:

a housing including a motor;

a first connector operably associated with the housing and configured to engage the instrument assembly including an irrigation passage defined therein; and

a cartridge member having a cartridge connector configured to slideably engage and hold the cartridge member relative to the handpiece, the cartridge member having a plurality of internal components including an irrigation line, an irrigation outlet, and an antenna;

a second connector operably associated with the housing and configured to removably connect the cartridge member relative to the handpiece to connect the irrigation line to the handpiece,

wherein an irrigation fluid is able to flow from an irrigation source through the irrigation passage of the instrument assembly after the cartridge member is connected to the handpiece,

wherein the instrument assembly includes a first instrument assembly and a second instrument assembly, both the first instrument assembly and the second instrument assembly operably connected to the handpiece and disposed in fluid communication with the irrigation source through the cartridge member when connected to the handpiece, and

wherein the first instrument assembly is configured to be removed from the handpiece while the cartridge member is connected to the handpiece and the second instrument assembly is connected to the handpiece while the cartridge member is connected to the handpiece, wherein the cartridge member includes a slideable connection that, upon engagement with the handpiece, registers a plurality of internal components of the handpiece along the longitudinal axis for transverse mechanical engagement to or transverse electrical communication with the corresponding plurality of internal components of the cartridge member.

10. The system of claim 9 , wherein the cartridge member is fixedly connected to the irrigation line.

11. The system of claim 9 , wherein the second connector includes a rail and wherein the cartridge connector includes a groove, the rail including an exterior dimension that is received in the groove to connect the cartridge member to the handpiece.

12. The system of claim 9 , further comprising:

a first identification member associated with the first instrument assembly;

a second identification member associated with the second instrument assembly; and

wherein the antenna within the cartridge member is configured to interrogate the first identification member and the second identification member and transmit a signal based on the interrogation,

wherein the signal is configured to allow determination of an identify of either the first instrument assembly or the second instrument assembly.

13. The system of claim 9 , wherein the cartridge member further includes a control member configured to receive an input from a user to change an operation of at least one of the motor, a flow from the irrigation source, or combinations thereof.

14. The system of claim 9 , wherein the cartridge member further includes an indicator configured to provide an output to indicate a current operation of at least one of the motor, a flow from the irrigation source, or combinations thereof.
