1. A disposable loading unit comprising:
- a cartridge assembly;
a housing coupled to said cartridge assembly and configured for operable attachment to a surgical instrument;
an axial drive assembly 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 housing and operably interfacing with said axial drive assembly to selectively apply said rotary motion thereto; and
a power source axially movable within said housing 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, said power source configured for attachment to an axially movable control member of the surgical instrument such that said power source is axially moved from said disconnected position to one of said at least one connected positions upon attachment to the control member.

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.

10. A surgical instrument comprising:
-
a handle assembly; an elongated shaft coupled to said handle assembly an axially movable control member operably supported within said elongated shaft and being selectively axially movable in response to actuation motions applied thereto; and a disposable loading unit comprising; a housing coupled to said elongated shaft; a staple cartridge supported by said housing assembly; an axial drive assembly 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 housing and operably interfacing with said axial drive assembly to selectively apply said rotary motion thereto; and a power source axially movable within said housing from a disconnected position wherein said power source is disconnected from said motor to a first connected position wherein said power source provides power to said motor upon attachment to the control member. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
