Abstract

A detachable motor-powered surgical instrument is disclosed. 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 disposable loading unit configured for operable attachment to a surgical instrument configured to selectively generate at least one control motion for the operation of said disposable loading unit, said disposable loading unit comprising:

a carrier operably supporting a cartridge assembly therein;

an anvil supported relative to said carrier and being movable from an open position to closed positions upon application of at least one control motion thereto;

a housing coupled to said carrier, said housing including means for removably attaching said housing to the surgical instrument;

an axial drive assembly at least partially supported within said housing and being supported for selective axial travel through said cartridge assembly from a start position to an end position upon application of a rotary motion thereto, said axial drive assembly comprising a rotary shaft; and

a motor operably interfacing with said rotary shaft to selectively apply said rotary motion thereto, said motor configured to receive power from a power source such that said motor can only selectively receive power from said power source when said means for removably attaching said housing to the surgical instrument is operably coupled to the surgical instrument.

2. The disposable loading unit of claim 1, wherein said cartridge assembly comprises a plurality of staples removably stored therein.

3. The disposable loading unit of claim 2, wherein said axial drive assembly comprises a sled movable between said start position and said end position to eject said staples from said cartridge assembly.

4. The disposable loading unit of claim 3, wherein said axial drive assembly further comprises a knife configured to incise tissue captured between said anvil and said cartridge assembly.

5. The disposable loading unit of claim 1, wherein said cartridge assembly is configured to be removed from said carrier and replaced with a different cartridge assembly.

6. A stapling system configured to be operably engaged with a surgical instrument system, said stapling system comprising:

a staple cartridge carrier;

a staple cartridge assembly supported by said staple cartridge carrier;

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

a housing, wherein said staple cartridge carrier extends from said housing, and wherein said housing comprises a housing connector removably attachable to the surgical instrument system;

a rotary shaft;

an axial drive member operably engaged with said rotary shaft, wherein said axial drive member is selectively movable through said staple cartridge assembly from a start position to an end position when a rotary motion is applied to said rotary shaft; and

an electric motor operably interfacing with said rotary shaft to selectively apply said rotary motion to said rotary shaft, wherein said electric motor is configured to receive power from a power source such that said electrical motor can only selectively receive power from said power source when said housing connector is attached to the surgical instrument.

7. The stapling system of claim 6, wherein said staple cartridge assembly comprises a plurality of staples removably stored therein.

8. The stapling system of claim 7, wherein said axial drive member comprises a sled movable between said start position and said end position to eject said staples from said staple cartridge assembly.

9. The stapling system of claim 8, wherein said axial drive member further comprises a knife configured to incise tissue captured between said anvil and said staple cartridge assembly.

10. The stapling system of claim 6, wherein said staple cartridge assembly is configured to be removed from said staple cartridge carrier and replaced with a different cartridge assembly.

11. A stapling system configured to be operably engaged with a surgical instrument system, said stapling system comprising:

a staple cartridge carrier;

a staple cartridge body supported by said staple cartridge carrier;

a plurality of staples removably stored in said staple cartridge body;

12. The stapling system of claim 11, wherein said translatable drive member comprises a sled movable between a start position and an end position to eject said staples from said staple cartridge body.

13. The stapling system of claim 12, wherein said translatable drive member further comprises a knife configured to incise tissue captured between said anvil and said staple cartridge body.

14. The stapling system of claim 11, wherein said staple cartridge body is configured to be removed from said staple cartridge carrier and replaced with a different staple cartridge body.

15. A stapling system configured to be operably engaged with a surgical instrument system, said stapling system comprising:

a staple cartridge carrier;

a staple cartridge body supported by said staple cartridge carrier;

a plurality of staples removably stored in said staple cartridge body;

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

a housing, wherein said staple cartridge carrier extends from said housing, and wherein said housing is removably coupled to the surgical instrument system;

a drive system, comprising;

a rotatable shaft comprising a threaded portion; and

a translatable drive member operably engaged with said threaded portion, wherein said translatable drive member is selectively movable through said staple cartridge body when a rotary motion is applied to said rotatable shaft; and

an electric motor system operably coupled with said rotatable shaft, wherein said electric motor system comprises a first state when said housing is coupled to the surgical instrument and a second state when said housing is not coupled to the surgical instrument, wherein said electric motor is configured to receive power from a power supply when said electrical motor system is in said first state, and wherein said electric motor system is decoupled from the power supply when said electric motor system is in said second state.

16. The stapling system of claim 15, wherein said translatable drive member comprises a sled movable between a start position and an end position to eject said staples from said staple cartridge body.

17. The stapling system of claim 16, wherein said translatable drive member further comprises a knife configured to incise tissue captured between said anvil and said staple cartridge body.

18. The stapling system of claim 15, wherein said staple cartridge body is configured to be removed from said staple cartridge carrier and replaced with a different staple cartridge body.
