Abstract

A surgical stapling assembly comprises a housing, wherein the housing comprises an engagement member for removably coupling the housing to a surgical system. The surgical stapling assembly further comprises a first jaw and a second jaw. The surgical stapling assembly further comprises a drive member and a motor positioned in the housing, wherein the motor is operable to selectively move the drive member. The surgical stapling assembly further comprises at least one electrical contact supported by the housing, wherein the at least one electrical contact is operable to supply power from a power source to the motor only when the housing is operably attached to the surgical system.

Claims

1. A surgical cutting and stapling instrument, comprising:

a housing comprising at least one engagement member for removably coupling said housing to a surgical system;

first and second jaws;

a drive member movable axially relative to said first and second jaws;

a motor positioned in said housing, wherein said motor is configured to selectively move said drive member between a starting position and an ending position relative to said first and second jaws; and

at least one battery contact positioned in said housing, wherein said at least one battery contact is configured to permit power to be supplied to said motor only when said housing is operably attached to the surgical system.

2. The surgical cutting and stapling instrument of claim 1, wherein one of said first and second jaws comprises a staple cartridge.

3. A surgical stapling assembly, comprising:

a housing configured to be removably coupled to a robotic surgical system;

first and second jaws;

a drive member movable axially relative to said first and second jaws;

a motor positioned in said housing, wherein said motor is configured to selectively move said drive member between a starting position and an ending position relative to said first and second jaws; and

at least one battery contact configured to permit power to be supplied to said motor only when said housing is operably attached to the robotic surgical system.

4. The surgical stapling assembly of claim 3, wherein one of said first and second jaws comprises a staple cartridge.

5. A surgical cutting and stapling instrument, comprising:

a housing comprising at least one engagement member for removably coupling said housing to a robotic surgical system;

a carrier;

a surgical staple cartridge operably positioned in said carrier;

an anvil movable relative to said carrier;

a drive member comprising a distal cutting edge configured for axial travel relative to said carrier;

a motor configured to move said drive member between a starting position and an ending position; and

a plurality of battery contacts configured to permit power to be supplied to said motor only when said housing is operably attached to the robotic surgical system.

6. A surgical stapling assembly, comprising:

a housing comprising an engagement member for removably coupling said housing to a surgical system;

a first jaw;

a second jaw;

a drive member moveable from a starting position toward an ending position;

a motor positioned in said housing, wherein said motor is operable to selectively move said drive member; and

at least one electrical contact supported by said housing, wherein said at least one electrical contact is operable to supply power from a power source to said motor only when said housing is operably attached to the surgical system.

7. The surgical stapling assembly of claim 6, wherein one of said first and second jaws comprises a staple cartridge.
