1. An auxiliary device for use in a surgical stapler comprising:
- a nozzle assembly including a nozzle body defining a cavity and having a discharge port and a compression assembly movably mounted within the cavity of the nozzle body and having a compression roller, the compression assembly being movable between a proximal position wherein the compression roller is spaced from the discharge port to a distal position wherein the compression roller is substantially adjacent the discharge port; and
a drive mechanism operatively connected to said surgical stapler and configures to move the compression assembly between the proximal and distal positions, wherein the compression roller of the compression assembly urges material contained within the cavity toward the discharge port as the compression assembly moves between the proximal and distal positions.

Abstract
There is disclosed an auxiliary device for injecting material between the jaws of a surgical stapler. The auxiliary device includes a nozzle assembly having a discharge port and a compression assembly having at least one compression roller for forcing material out of the discharge port. The disclosed compression rollers may be formed of an incompressible or compressible material. The auxiliary device also includes a drive mechanism for moving the compression assembly within a nozzle body of the nozzle assembly. There is also disclosed a rupturable capsule for retaining material to be dispensed.

13. An auxiliary device for use in a surgical stapler comprising:
-
a nozzle assembly including a nozzle body defining a cavity and having a discharge port; a compression assembly movably mounted within the cavity of the nozzle body and having a first compression roller and a second compression roller, the first and second compression rollers being movable between a proximal position spaced from the discharge port to a distal position substantially adjacent the discharge port; and a drive mechanism operable to move the first and second compression rollers between the proximal and distal positions, wherein the first and second compression rollers urge material contained within the cavity toward the discharge port as the first and second compression rollers move between the proximal and distal positions.

14. An auxiliary device for use in a surgical stapler comprising;
-
a surgical stapler having a handle having a first jaw containing a staple containing cartridge and a second jaw movable relative to the first jaw and having an anvil surface; a nozzle assembly mounted on one of the first and jaws, the nozzle assembly including a nozzle body defining a cavity and having a discharge port open to a face of one of the first and second jaws; a compression assembly movably mounted within the cavity of the nozzle body and having a compression roller, the compression roller being movable between a proximal position spaced from the discharge port to a distal position substantially adjacent the discharge port; and a drive mechanism operable to move the compression roller between the proximal and distal positions, wherein the compression roller urges material contained within the cavity toward the discharge port as the compression roller moves between the proximal and distal positions.
