Powered surgical cutting and stapling apparatus with manually retractable firing system
A surgical system is disclosed including a frame, an electric motor, a power source configured to supply power to the electric motor, a firing member, a manual release for retracting the firing member, and a controller for de-energizing the electric motor while a retraction motion is applied to the firing member. The electric motor is configured to impart a firing motion to the firing member.
1. A surgical system, comprising:
a frame;
an electric motor;
a power source configured to supply power to said electric motor;
a firing member, wherein said electric motor is configured to impart a firing motion to said firing member;
a manual release for retracting said firing member; and
means for de-energizing said electric motor while a retraction motion is applied to said firing member.
2. The surgical system of claim 1 , wherein said power source cannot apply a voltage potential to said electric motor while said retraction motion is applied to said firing member.
3. The surgical system of claim 1 , wherein said means for de-energizing is configurable between a first state and a second state, and wherein said means for de-energizing de-energizes said electric motor in said second state.
4. The surgical system of claim 3 , wherein said manual release is configured to transition said means for de-energizing toward said second state.
5. The surgical system of claim 4 , wherein said means for de-energizing is unable to transition to said first state after being placed in said second state.
6. The surgical system of claim 4 , wherein said means for de-energizing is resettable to said first state after being placed in said second state.
7. The surgical system of claim 1 , wherein said manual release is configured to mechanically decouple said electric motor from said firing member.
8. The surgical system of claim 1 , further comprising a second means for de-energizing said electric motor while a retraction motion is applied to said firing member.
9. A surgical system, comprising:
a nozzle;
an electric motor;
a power source configured to energize said electric motor;
a firing member, wherein said electric motor is configured to impart a firing motion to said firing member;
a retraction system for retracting said firing member; and
means for preventing said power source from energizing said electric motor while a retraction motion is applied to said firing member.
10. The surgical system of claim 9 , wherein said means for preventing is configurable between a first configuration and a second configuration, and wherein said means for preventing prevents said power source from energizing said electric motor in said second configuration.
11. The surgical system of claim 10 , wherein said retraction system is configured to transition said means for preventing toward said second configuration.
12. The surgical system of claim 11 , wherein said means for preventing is unable to transition to said first configuration after being placed in said second configuration.
13. The surgical system of claim 11 , wherein said means for preventing is resettable to said first configuration after being placed in said second configuration.
14. The surgical system of claim 9 , wherein said retraction system is configured to mechanically decouple said electric motor from said firing member.
15. The surgical system of claim 9 , further comprising a second means for preventing said power source from energizing said electric motor while said retraction motion is applied to said firing member.
16. A surgical system, comprising:
a housing;
an electric motor;
a power source configured to provide power to said electric motor;
a firing member, wherein said electric motor is configured to impart a firing motion to said firing member;
means for retracting said firing member; and
means for interrupting said power source from said electric motor while a retraction motion is applied to said firing member.
17. The surgical system of claim 16 , wherein said means for interrupting is configurable between a first state and a second state, and wherein said means for interrupting interrupts said power source from providing said power to said electric motor in said second state.
18. The surgical system of claim 17 , wherein said means for retracting is configured to transition said means for interrupting toward said second state.
19. The surgical system of claim 18 , wherein said means for interrupting is unable to transition to said first state after being placed in said second state.
20. The surgical system of claim 18 , wherein said means for interrupting is resettable to said first state after being placed in said second state.
