Patent ID: 7866524

Claim:
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, the nozzle body being longitudinally tapered; and a compression assembly movably mounted within the cavity of the nozzle body and having a compression roller, a drive block, a clevis arm having first and second ends and pivotally mounted to the drive block at the first end and a spindle mounted to the clevis arm at the second end, the first roller mounted on the spindle; 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 engagable with the drive block, the drive mechanism configured 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.
