DISPOSABLE LOADING UNIT WITH FIRING INDICATOR
First Claim
1. A disposable loading unit for attachment to a surgical stapling apparatus, said disposable loading unit comprising:
- a carrier;
a staple cartridge supported in said carrier;
an anvil assembly movably coupled to said carrier for selective movable travel between open and closed positions relative to said staple cartridge;
an axial drive assembly having a distal end portion constructed to move in a distal direction from a start position to an end position through said staple cartridge in response to a drive motion imparted to said axial drive assembly from the surgical stapling apparatus;
a housing coupled to said carrier and configured for operable attachment to the surgical stapling apparatus; and
a firing indicator assembly on at least one of said anvil assembly and said housing, said firing indicator assembly cooperating with said axial drive assembly for indicating a position of said axial drive assembly as said axial drive assembly is driven from said start position to said end position.

Abstract
A disposable loading unit for operable attachment to a surgical stapling apparatus. The disposable loading unit may have a carrier that supports a staple cartridge therein, an anvil assembly that is movably coupled to the carrier, and an axial drive assembly that is constructed to move in a distal direction from a start position to an end position through the staple cartridge in response to a drive motion imparted to the axial drive assembly from the surgical stapling apparatus. A firing indicator is provided on at least one of the anvil assembly and housing for indicating a position of the axial drive assembly as the axial drive assembly is driven from the start position to the end position.
