Abstract

A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

Claims

1. A stapling system configured to be operably attachable to and detachable from a control unit, said stapling system comprising:

an end effector, comprising;

a staple cartridge carrier;

a staple cartridge assembly supported by said staple cartridge carrier, wherein said staple cartridge assembly comprises a plurality of staples removably stored therein; and

an anvil supported relative to said staple cartridge carrier and movable from an open position to a closed position;

a firing member configured to eject said staples from said staple cartridge assembly; and

a housing, comprising;

a connector portion attachable to and detachable from the control unit; and

an electric motor operably interfacing with said firing member.

2. The stapling system of claim 1, wherein said housing further comprises an electrical contact in communication with said electric motor.

3. The stapling system of claim 1, further comprising a lock portion configured to releasably hold said connector portion to the control unit.

4. The stapling system of claim 1, wherein said firing member comprises a sled movable along an axis between a start position and an end position to eject said staples from said staple cartridge assembly.

5. The stapling system of claim 4, wherein said sled comprises at least one ramped surface configured to lift said staples.

6. The stapling system of claim 4, wherein said firing member further comprises a knife configured to incise tissue captured between said anvil and said staple cartridge assembly.

7. The stapling system of claim 1, wherein said staple cartridge assembly is configured to be removed from said staple cartridge carrier and replaced with a different staple cartridge assembly.

8. The stapling system of claim 1, further comprising a threaded rotatable shaft operably engaged with said electric motor, wherein said electric motor is configured to rotate said threaded rotatable shaft, and wherein said threaded rotatable shaft is threadably engaged with said firing member.

9. A stapling system configured to be releasably attachable to and releasably detachable from a surgical instrument system, said stapling system comprising:
