Abstract

A surgical kit is disclosed. The kit comprises a surgical instrument, a loading unit, and a plurality of cartridge members. The surgical instrument includes a handle assembly, and an elongated portion extending distally from the handle assembly and defining a longitudinal axis. The loading unit is configured for selective engagement with a distal portion of the elongated portion. The loading unit including an anvil assembly and a cartridge channel. Each cartridge member includes a plurality of retention slots with at least some of the slots including fasteners therein. Each cartridge member is configured for selective mechanical engagement with the cartridge channel, and includes a longitudinal length and a working length. The working length is the longitudinal distance along retention slots having fasteners therein. The longitudinal length of each cartridge member is substantially the same, and the working length of at least two of the plurality of cartridge members is different.

Claims

1. A surgical kit, comprising:

a surgical instrument including a handle assembly, and an elongated portion extending distally from the handle assembly and defining a longitudinal axis;

a loading unit configured for selective engagement with a distal portion of the elongated portion, the loading unit including an anvil assembly and a cartridge channel;

first and second cartridge members, each cartridge member containing a plurality of retention slots, at least some retention slots of the plurality of retention slots including fasteners therein, each cartridge member being configured for selective mechanical engagement with the cartridge channel, each cartridge member having a longitudinal length and a working length, the working length being a longitudinal distance along the retention slots of the plurality of retention slots having fasteners therein, the longitudinal lengths of the first and second cartridge members are substantially the same, the working length of the first cartridge member being different from the working length of the second cartridge member; and

a tissue stop pivotably coupled to the second cartridge member and disposed adjacent a proximal end thereof, the tissue stop disposed proximally of the working length.

2. The kit of claim 1, wherein the working length of the first cartridge member is about 60 mm.

3. The kit of claim 2, wherein the working length of the second cartridge member is about 45 mm.

4. The kit of claim 3, further including a third cartridge member having a working length of about 30 mm.

5. The kit of claim 4, wherein the longitudinal length of each cartridge member is about 65 mm.

6. The kit of claim 4, wherein the third cartridge member includes a tissue stop disposed adjacent a proximal end thereof, and wherein the tissue stop is disposed proximally of the working length of the third cartridge member.

7. The kit of claim 1, wherein each cartridge member is configured for a snap-fit connection with the cartridge channel.

8. A surgical kit, comprising:

a surgical instrument including a handle assembly, an elongated portion extending distally from the handle assembly and defining a longitudinal axis, and an end effector disposed adjacent a distal portion of the elongated portion, the end effector including an anvil assembly and a cartridge channel;

a first cartridge member configured for selective mechanical engagement with the cartridge channel, the first cartridge member including a plurality of retention slots, at least some retention slots of the plurality of retention slots including fasteners therein, the first cartridge member having a longitudinal length and a working length, the working length being a longitudinal distance along the retention slots of the plurality of retention slots having fasteners therein;

a second cartridge member configured for selective mechanical engagement with the cartridge channel, the second cartridge member including a plurality of retention slots, at least some retention slots of the plurality of retention slots including fasteners therein, the second cartridge member having a longitudinal length and a working length, the working length being a longitudinal distance along the retention slots of the plurality of retention slots having fasteners therein, the longitudinal length of the first cartridge member is substantially the same as the longitudinal length of the second cartridge member, the working length of the first cartridge member is different from the working length of the second cartridge member; and

a pivotable tissue stop coupled to the second cartridge member and disposed adjacent a proximal end thereof, the tissue stop disposed proximally of the working length.

9. The kit of claim 8, further comprising a third cartridge member configured for selective mechanical engagement with the cartridge channel, the third cartridge member including a plurality of retention slots, at least some retention slots of the plurality of retention slots including fasteners therein, the third cartridge member having a longitudinal length and a working length, the working length being a longitudinal distance along the retention slots of the plurality of retention slots having fasteners therein, the longitudinal length of the third cartridge member is substantially the same as the longitudinal length of the second cartridge member, the working length of the third cartridge member is different from the working length of the first cartridge member and is different from the working length of the second cartridge member.

10. The kit of claim 9, wherein the working length of the first cartridge member is about 60 mm, wherein the working length of the second cartridge member is about 45 mm, and wherein the working length of the third cartridge member is about 30 mm.
