Abstract

A combination comprises a handle module that is attachable to a detachable shaft module for collectively performing a surgical procedure, a first removable, rechargeable battery pack connectable to the handle module for providing electric power to the handle module during a surgical procedure and a charging station for charging the first battery pack when the battery pack is removed from the handle module and inserted into the charging station. The charging station comprises means for rapidly charging the first battery pack when a rapid charge user input for the battery pack is received by the charging station.

First claim

What is claimed is:

1 . A combination, comprising:
a handle module that is attachable to a detachable shaft module for collectively performing a surgical procedure; a removable, rechargeable battery pack connectable to the handle module for providing electric power to the handle module during a surgical procedure; and a charging station for charging the battery pack when the battery pack is removed from the handle module and inserted into the charging station, wherein the charging station comprises circuitry for rapidly charging the battery pack when a rapid charge user input for the battery pack is received by the charging station.

2 . The combination of claim 1 , wherein the charging station comprises a display for displaying the charge status of the battery pack.

3 . The combination of claim 2 , wherein the charging station comprises a user interface through which a user inputs the rapid charge user input to the charging station.

4 . The combination of claim 3 , wherein the user interface comprises a button on the charging station which is actuatable to provide the charging station with the rapid charge user input.

5 . The combination of claim 1 , wherein the circuitry for rapidly charging the battery pack comprises circuitry for changing a charging profile for the battery pack.

6 . The combination of claim 5 , wherein the circuitry for changing the charging profile for the battery pack comprises:
a voltage regulator connected to the battery pack; and a charging controller circuit connected to the voltage regulator.

7 . The combination of claim 1 , wherein the circuitry for rapidly charging the battery pack comprises a charge-storing device of the charging station, and wherein charge stored on the charge-storing device is used to charge the battery pack.

8 . The combination of claim 7 , wherein the charge-storing device comprises a supercapacitor.

9 . The combination of claim 8 , wherein the charging station further comprises circuitry for discharging the first battery pack to the supercapacitor.

10 . The combination of claim 7 , wherein the charge-storing device comprises one or more battery cells internal to the charging station.

11 . The combination of claim 7 , wherein the charge-storing device comprises a plurality of battery cells internal to the charging station, and wherein the circuitry for rapidly charging the battery pack comprises circuitry for charging the battery pack with the plurality of battery cells.

12 . The combination of claim 11 , wherein the plurality of battery cells are connected in series.

13 . The combination of claim 11 , wherein the plurality of battery cells are connected as parallel current sources.

14 . The combination of claim 1 , wherein the charging station further comprises circuitry for discharging the first battery pack to the internal plurality of battery cells.

15 . The combination of claim 1 , wherein the battery pack comprises a first battery pack, wherein the charging station comprises:
a first charging receptacle for receiving the first battery pack to charge the first battery pack; and a second charging receptacle for receiving a second battery pack to charge the second battery pack, and wherein the circuitry for rapidly charging the first battery pack comprises circuitry for charging the first battery pack with charge stored on the second battery pack.

16 . The combination of claim 15 , wherein the charging station further comprises circuitry for discharging the first battery pack to the second battery pack.

17 . The combination of claim 15 , wherein the charging station comprises a display for displaying the charge status of the first battery pack and the second battery pack.

18 . The combination of claim 1 , wherein the charging station comprises means for automatically securing the battery pack to the charging station when the battery pack is not ready for use in the handle module for a surgical procedure.

19 . A surgical instrument system, comprising:
a handle module for performing a surgical procedure; a removable, rechargeable battery pack connectable to the handle module for providing electric power to the handle module during the surgical procedure; and a charging station for charging the battery pack, wherein the charging station comprises circuitry for charging the handle module under two operating conditions:
a first operating condition in which the battery pack is charged from a primary power source; and
a second operating condition in which the battery pack is charged from the primary power source and a secondary power source in order to rapidly charge the battery pack in case the battery pack is urgently needed in the surgical procedure.

20 . The surgical instrument system of claim 19 , wherein the secondary power source comprises a second removable, rechargeable battery pack connectable to the handle module.
