Sealing pack assembly for use with endoscopic stitching device

An endoscopic stitching device comprising:

• an elongate shaft assembly including an axial rod extending therethrough;
• a tool assembly coupled with the elongate shaft assembly, the tool assembly including:
• first and second jaws operatively coupled with the axial rod of the elongate shaft assembly such that axial displacement of the axial rod transitions the first and second jaws between open and closed positions;
• and
• first and second needle receiving blades slidably disposed in the respective first and second jaws;
• and
• a sealing pack disposed in the elongate shaft assembly to inhibit passage of fluid into the elongate shaft assembly, the sealing pack defining:
• a central lumen configured to receive the axial rod therethrough, the central lumen including opposing planar portions and opposing arcuate portions, the opposing planar portions and opposing arcuate portions having a cross-section complementary to a cross-section of the axial rod;
• and
• first and second lumens dimensioned to receive the respective first and second needle receiving blades therethrough, the first and second lumens being separate from the central lumen, the sealing pack including a body portion, a plurality of outer lips extending outwardly from the body portion, and a plurality of inner lips extending inwardly from the central lumen, each outer lip of the plurality of outer lips configured to engage the elongate shaft assembly in a sealing relation, each inner lip of the plurality of inner lips configured to engage the axial rod in a sealing relation.
