First Claim
Patent Images
1. A surgical cartridge comprising:
- a cartridge body defining a path therethrough for operably receiving a firing member of a surgical instrument; and
an alignment member operably supported in the cartridge body and being configured to move the firing member from an inoperable configuration wherein firing member is misaligned with the path to an operable configuration wherein the firing member is in alignment with the path when the firing member is driven into contact therewith.

4. An end effector for a surgical instrument, the end effector comprising:
-
a support member comprising; a slot; and a lockout notch adjacent to said slot and wherein said end effector further comprises; a firing member movable between an inoperable configuration and an operable configuration, wherein said firing member is aligned with said slot and is structured to translate in said slot when in said operable configuration, and wherein said firing member is engaged with said lockout notch and misaligned with said slot when in said inoperable configuration. - View Dependent Claims (5, 6, 7, 8)

9. A surgical instrument comprising:
-
an elongate channel configured to removably support a cartridge therein, the cartridge comprising; a cartridge body; and an alignment member movably supported within the cartridge body for movement from a first position to a second position therein and wherein the surgical instrument further comprises; a firing member operably supported relative to the elongate channel for movement between a starting position and an ending position upon application of actuation motions thereto, the firing member being incapable from moving from the starting position to the ending position unless the firing member is in operable engagement with the alignment member in the cartridge body. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. An end effector for a surgical instrument, the end effector comprising:
-
an elongate channel configured to removably support a cartridge therein; a firing member operably supported relative to the elongate channel for movement between a starting and ending position; an implement drive shaft in operable engagement with the firing member for moving the firing member between the starting and ending positions upon applications of actuation motions thereto from a drive arrangement, the implement drive shaft being moveable from an inoperable position wherein the implement drive shaft is out of operable engagement with the drive arrangement to an operable position wherein the implement drive shaft is in operable engagement with the drive arrangement; and an alignment member movably supported for contact with the implement drive shaft to move the implement drive shaft from the inoperable position to the operable position upon installation of a cartridge in the elongate channel.

17. A surgical instrument comprising:
-
an elongate channel; a cartridge removably supported in the elongate channel; a firing member operably supported relative to the elongate channel for movement between a starting and ending position; an implement drive shaft in operable engagement with the firing member for moving the firing member between the starting and ending positions upon applications of actuation motions thereto from a drive arrangement, the implement drive shaft being moveable from an inoperable position wherein the implement drive shaft is out of operable engagement with the drive arrangement to an operable position wherein the implement drive shaft is in operable engagement with the drive arrangement; and an alignment member movably supported for contact with the implement drive shaft to move the implement drive shaft from the inoperable position to the operable position upon installation of a cartridge in the elongate channel. - View Dependent Claims (18, 19)
