Tamper proof circuit for surgical instrument battery pack

1. A surgical instrument, comprising:

a shaft;

an end effector extending distally from said shaft; and

a housing extending proximally from said shaft, said housing comprising:

a motor configured to generate at least one motion to effectuate said end effector; and

a power source configured to supply power to said surgical instrument, wherein said power source comprises:

a casing;

a data storage unit;

an interface configured to permit an external device to download data stored in the data storage unit, wherein said interface is enclosed by said casing;

a deactivation mechanism comprising a severable connector, the severable connector coupling the interface and the data storage unit; and

wherein the severable connector is severed when the casing is opened, thereby interrupting access via the interface to the data stored in the data storage unit.

2. The surgical instrument of claim 1 , wherein said deactivation mechanism is activated by disassembly of said power source.

3. The surgical instrument of claim 1 , wherein said deactivation mechanism is triggerable by breach of said casing.

4. The surgical instrument of claim 1 , wherein said power source comprises a battery pack.

5. The surgical instrument of claim 4 , wherein said battery pack is rechargeable.

6. The surgical instrument of claim 1 , wherein said power source is detachably coupled to said housing.

7. The surgical instrument of claim 1 , wherein said data storage unit is positioned within said casing.

8. The surgical instrument of claim 1 , wherein the interface comprises a wired interface.

9. The surgical instrument of claim 1 , wherein the interface comprises a wireless interface.

10. A surgical instrument, comprising:

a shaft;

an end effector extending distally from said shaft; and

a housing extending proximally from said shaft, said housing comprising:

a motor configured to generate at least one motion to effectuate said end effector; and

a power source configured to supply power to said motor, wherein said power source comprises:

a casing;

a memory unit;

a data access portal configured to permit an external device to download data stored in said memory unit, wherein said data access portal is only accessible by breach of said casing;

a battery pack; and

a deactivation mechanism comprising a circuit connected to the battery pack, the circuit couplable to an external power source to permit the external power source to recharge the battery pack;

the circuit comprising a breakable portion;

wherein the breakable portion is broken if the casing is breached, thereby rendering the battery pack incapable of being recharged via the circuit.

11. The surgical instrument of claim 10 , wherein said casing comprises:

a first shell; and

a second shell separably coupled to said first shell, wherein said circuit is breakable by separating said first shell from said second shell.

12. A surgical instrument, comprising:

a shaft;

an end effector extending distally from said shaft; and

a housing extending proximally from said shaft, said housing comprising:

a motor configured to generate at least one motion to effectuate said end effector; and

a power source configured to supply power to said motor, wherein said power source comprises:

a casing comprising a first shell and a second shell

separably coupled to said first shell;

a memory unit;

a data access portal configured to permit an external device to download data stored in said memory unit, wherein said data access portal is only accessible by separating said first shell from said second shell;

a battery pack; and

a deactivation mechanism comprising a circuit connected to the battery pack, the circuit couplable to an external power source to permit the external power source to recharge the battery pack;

the circuit comprising a breakable portion;

wherein the breakable portion is broken if the casing is breached, thereby rendering the battery pack incapable of being recharged via the circuit.
