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.
Claims20
A surgical cutting and stapling instrument comprising:
- a housing including at least one engagement member for removably coupling the housing to an actuator arrangement;
- first and second jaws operably coupled to the housing such that at least one said jaw is selectively movable relative to the other said jaw;
- an axial drive assembly movably supported for selective axial travel relative to said first and second jaws;
- a motor supported by said housing and operably interfacing with the axial drive assembly to selectively move said axial drive assembly between a starting position and an ending position relative to the first and second jaws;
- and
- a contact arrangement supported by said housing and configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.
A surgical cutting and stapling instrument comprising:
- a housing including at least one engagement member for removably coupling the housing to an actuator arrangement;
- a carrier operably coupled to the housing;
- a surgical staple cartridge operably supported in the carrier;
- an anvil movably supported relative to the carrier;
- a drive beam including a distal cutting edge supported for axial travel relative to the carrier;
- a motor supported by said housing and operably interfacing with the drive beam to selectively move said drive beam between a starting position and an ending position;
- and
- a contact arrangement supported by said housing and configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.
A surgical cutting and stapling instrument comprising:
- an end effector configured to cut and staple tissue;
- a housing coupled to the end effector and including means for removably coupling the housing to an actuator arrangement;
- a motor supported by said housing and operably interfacing with a portion of the end effector for selective actuation thereof;
- and
- a contact arrangement supported by said housing and configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.
