Detachable motor powered surgical instrument
First Claim
1. A removable loading unit configured to be operably attached to a surgical device which is configured to selectively generate at least one control motion for the operation of said removable loading unit, said removable loading unit comprising:
- a cartridge assembly comprising a plurality of staples deployable from said cartridge assembly;
a carrier operably supporting said cartridge assembly;
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 device;
a rotary drive at least partially supported within said housing;
a motor attached to said housing and operably interfacing with said rotary drive to selectively apply a rotary motion thereto, wherein said motor is configured to receive power from a power source such that said motor can only selectively receive power from the power source when said means for removably attaching said housing to the surgical device is operably coupled to the surgical device; and
a linear member coupled with said rotary drive which is configured to move axially upon the application of a rotary motion thereto from said motor to deploy said staples.

Abstract
A removable stapling attachment configured to be operably attached to a surgical device is disclosed. The removable stapling attachment comprises a staple cartridge carrier and a staple cartridge body. The removable stapling attachment further comprises a plurality of staples removably stored in the staple cartridge body, an anvil supported relative to the staple cartridge carrier and movable from an open position to a closed position, and a housing. The housing is removably attachable to the surgical device. The removable stapling attachment further comprises an electric motor attached to the housing. The electric motor is configured to produce rotational motion. The electric motor selectively receives power from a power source only when the housing is coupled to the surgical device. The removable stapling attachment further comprises drive means for converting the rotational motion produced by the electric motor to translational motion to eject the staples from the staple cartridge body.

2. A stapling sub-system configured to be operably engaged with a surgical system, said stapling sub-system comprising:
-
a staple cartridge carrier; a staple cartridge assembly supported by said staple cartridge carrier, wherein said staple cartridge assembly comprises a plurality of staples; 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 system; and a rotary drive system, comprising a rotary shaft; a translatable drive member operably engaged with said rotary shaft, wherein said translatable drive member is selectively translatable to deploy said staples when a rotary motion is applied to said rotary shaft; and an electric motor attached to said housing, wherein said electric motor is operably interfacing with said rotary shaft to selectively apply said rotary motion to said rotary shaft, wherein said electric motor is operably disconnected from a power source when said housing is not attached to the surgical system, and wherein said electric motor is operably connected to the power source when said housing is attached to the surgical system.

3. A removable stapling attachment configured to be operably attached to a surgical device, said removable stapling attachment comprising:
-
a staple cartridge carrier; a staple cartridge body supported by said staple cartridge carrier, wherein said staple cartridge body comprises a proximal end and a distal end; 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 attachable to the surgical device; an electric motor attached to said housing, wherein said electric motor is configured to produce rotational motion, wherein said electric motor selectively receives power from a power source only when said housing is coupled to said surgical device; and drive means for converting the rotational motion produced by said electric motor to translational motion to eject said staples from said staple cartridge body.
