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