Disposable motor-driven loading unit for use with a surgical cutting and stapling apparatus
First Claim
1. A disposable loading unit configured for operable attachment to a surgical instrument configured to selectively generate at least one control motion, for operation of the disposable loading unit, the disposable loading unit comprising:
- a carrier operably supporting a cartridge assembly therein;
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 instrument;
an axial drive assembly at least partially supported within the housing and being supported for selective axial travel through said cartridge assembly from a start position to an end position upon application of a rotary motion thereto; and
a motor supported within said housing and operably interfacing with said axial drive assembly to selectively apply said rotary motion thereto, said motor configured to receive power from a power source such that said motor can only selectively receive power from said power source when said means for removably attaching on the housing is operably coupled to a portion of the surgical instrument.

Abstract
A self contained motor-powered disposable loading unit for use with a surgical cutting and stapling apparatus. The disposable loading unit may contain a battery that is retained in a disconnected position when the disposable loading unit is not in use and is moved to a connected position when the disposable loading unit is coupled to the surgical cutting and stapling apparatus to permit the motor to be selectively powered thereby. Indicators may be supported on the disposable loading unit to indicate when the axial drive assembly thereof is in a starting position and an ending position. Another indicator may be provided to indicate when the anvil assembly is in a closed position.

4. A surgical stapling unit comprising:
-
a cartridge assembly operably supporting a plurality of staples therein configured for attachment to an elongated support member; an anvil supported relative to said cartridge assembly and being movable from an open position to a closed positions upon application of at least one control motion thereto; an axial drive assembly operably supported for selective axial travel through said cartridge assembly from a start position to an end position upon application of a rotary motion thereto; a motor supported within said elongated support member and operably interfacing with said axial drive assembly to selectively apply said rotary motion thereto; and a power source axially movable within said elongated support member from a disconnected position wherein said power source is disconnected from said motor to at least one connected position wherein said power source provides power to said motor upon application of an actuation motion from an axially movable control member. - View Dependent Claims (5, 6, 7, 8, 9, 10)
