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.
Claims4
1-20. (canceled)
A loading unit configured to be operably attached to a surgical instrument, wherein the surgical instrument is configured to selectively generate at least one control motion for operating said loading unit, and wherein said loading unit comprises:
- a carrier operably supporting a cartridge assembly therein;
- an anvil supported relative to said carrier, wherein said anvil is movable from an open position toward a closed position;
- a housing coupled to said carrier, wherein said housing is removably attachable to the surgical instrument;
- an axial drive assembly at least partially supported within said housing, wherein said axial drive assembly is supported for selective axial travel through said cartridge assembly from a start position toward an end position upon the application of a rotary motion thereto;
- and
- a motor supported within said housing, wherein said motor operably interfaces with said axial drive assembly to selectively apply said rotary motion thereto, and wherein said motor is configured to receive power from a power source such that said motor can only selectively receive power from said power source when said housing is operably coupled to the surgical instrument.
A loading assembly configured to be operably attached to a surgical instrument system, wherein the surgical instrument system is configured to selectively generate at least one control motion for operating said loading assembly, and wherein said loading assembly comprises:
- a carrier operably supporting a staple cartridge assembly therein;
- an anvil movable from an open position toward a closed position;
- a housing, wherein said housing is removably attachable to the surgical instrument system;
- an axial drive assembly supported for selective axial travel through said staple cartridge assembly from a start position toward an end position upon the application of a rotary motion thereto;
- and
- a motor supported within said housing, wherein said motor operably interfaces with said axial drive assembly to selectively apply said rotary motion thereto, and wherein said motor is configured to receive power from a power source such that said motor can only selectively receive power from said power source when said housing is operably coupled to the surgical instrument system.
A stapling assembly configured to be operably attached to a surgical instrument system, wherein the surgical instrument system is configured to selectively generate at least one control motion for operating said stapling assembly, and wherein said stapling assembly comprises:
- a jaw configured to support a staple cartridge assembly;
- an anvil movable from an open position toward a closed position;
- a housing, wherein said housing is removably attachable to the surgical instrument system;
- a driver movable axially through said staple cartridge assembly from a start position toward an end position upon the application of a rotary motion thereto;
- and
- a motor positioned in said housing, wherein said motor operably interfaces with said driver to selectively apply said rotary motion thereto, and wherein said motor is configured to receive power from a power source such that said motor can only selectively receive power from said power source when said housing is operably coupled to the surgical instrument system.
