Abstract

A surgical stapling device includes a clamp slide assembly and an end effector that includes a cartridge module. The clamp slide assembly includes a distal portion that defines a curved slot and includes a linear section that defines linear channels. The cartridge module includes a curved module body that includes a linear section that includes linear ribs. The linear ribs are received within the linear channels to facilitate loading of the cartridge module into the distal portion of the clamp slide assembly in a linear fashion.

First claim

What is claimed is:

1. A stapling device comprising:
an elongate body having a proximal portion and a distal portion;
a clamp slide assembly having a distal portion that defines a curved pocket, the distal portion of the clamp slide assembly including spaced walls that define a linear section of the distal portion of the clamp slide assembly, the linear section of the distal portion of the clamp slide assembly positioned on a first end portion of the clamp slide assembly and defining linear channels; and
an end effector supported on the distal portion of the elongate body, the end effector including:
an end effector frame having a U-shaped configuration and including a distal transverse portion, a proximal transverse portion, and a longitudinal portion, the longitudinal portion connecting the distal transverse portion to the proximal transverse portion to define a gap between the distal transverse portion and the proximal transverse portion, the distal portion of the clamp slide assembly positioned within the gap and movable between retracted and advanced positions;
an anvil assembly supported on the distal transverse portion of the end effector frame; and
a cartridge module removably received within the curved pocket of the clamp slide assembly, the cartridge module including a module body having a curved configuration with a linear section, the linear section of the module body including linear ribs that are received in the linear channels in the linear section of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly.

2. The stapling device of claim 1 , wherein each of the linear ribs of the module body includes a raised bumper.

3. The stapling device of claim 2 , wherein each of the spaced side walls defining the linear section of the distal portion of the clamp slide assembly defines a pocket that communicates with one of the linear channels of the clamp slide assembly, the pockets receiving the raised bumpers when the cartridge module is loaded into the clamp slide assembly.

4. The stapling device of claim 3 , wherein the spaced side walls defining the linear section of the distal portion of the clamp slide assembly define through bores, each of the through bores communicating with one of the pockets.

5. The stapling device of claim 4 , wherein each of the raised bumpers includes indicia, the indicia visible through the through bores in the spaced side walls of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly.

6. The stapling device of claim 5 , wherein the linear section of the cartridge module includes overhangs that define linear channels, the linear channels receiving portions of the spaced side walls of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly.

7. The stapling device of claim 1 , wherein the module body of the cartridge module includes a proximal extension, and the cartridge module includes an alignment pin assembly that is positioned within the proximal extension.

8. The stapling device of claim 7 , further including an alignment pin pusher supported on the elongate body, the alignment pin pusher having a coupling portion that engages the alignment pin assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly, wherein the alignment pin pusher is movable to move the alignment pin assembly between retracted and advanced positions.

9. The stapling device of claim 8 , wherein the proximal extension defines a cutout, the cutout facilitating passage of the coupling portion of the alignment pin pusher into the proximal extension of the module body of the cartridge module.

10. A stapling device comprising:
a handle assembly;
an elongate body having a proximal portion and a distal portion, the proximal portion of the elongate body coupled to the handle assembly;
a clamp slide assembly having a distal portion that defines a curved pocket, the distal portion of the clamp slide assembly including spaced walls that define a linear section of the distal portion of the clamp slide assembly, the linear section of the distal portion of the clamp slide assembly positioned on a first end portion of the clamp slide assembly and defining linear channels;
an alignment pin pusher supported on the elongate body, the alignment pin pusher having a coupling portion; and
an end effector supported on the distal portion of the elongate body, the end effector including:
an end effector frame having a U-shaped configuration and including a distal transverse portion, a proximal transverse portion, and a longitudinal portion, the longitudinal portion connecting the distal transverse portion to the proximal transverse portion to define a gap between the distal transverse portion and the proximal transverse portion, the distal portion of the clamp slide assembly positioned within the gap and movable between retracted and advanced positions;
an anvil assembly supported on the distal transverse portion of the end effector frame;
a cartridge module removably received within the curved pocket of the clamp slide assembly, the cartridge module including a module body having a curved configuration with a linear section, the linear section of the module body including linear ribs that are received in the linear channels in the linear section of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly, the module body of the cartridge module including a proximal extension, the cartridge module including an alignment pin assembly that is positioned within the proximal extension, wherein the coupling portion of the alignment pin pusher engages the alignment pin assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly such that the alignment pin pusher is movable to move the alignment pin assembly between retracted and advanced positions.

11. The stapling device of claim 10 , wherein the proximal extension defines a cutout, the cutout facilitating passage of the coupling portion of the alignment pin pusher into the proximal extension of the module body of the cartridge module when the cartridge module is loaded into the distal portion of the clamp slide assembly.

12. The stapling device of claim 10 , wherein each of the linear ribs of the module body includes a raised bumper.

13. The stapling device of claim 12 , wherein each of the spaced side walls defining the linear section of the distal portion of the clamp slide assembly defines a pocket that communicates with one of the linear channels of the clamp slide assembly, the pockets receiving the raised bumpers when the cartridge module is loaded into the clamp slide assembly.

14. The stapling device of claim 13 , wherein each of the raised bumpers includes indicia, the indicia visible through the through bores in the spaced side walls of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly.

15. The stapling device of claim 14 , wherein the linear section of the cartridge module includes overhangs that define linear channels, the linear channels receiving portions of the spaced side walls of the distal portion of the clamp slide assembly when the cartridge module is loaded into the distal portion of the clamp slide assembly.

16. An end effector for a stapling device comprising:
a clamp slide
