Abstract
A surgical stapling instrument includes an anvil assembly, a shell assembly, and an adapter assembly. The adapter assembly includes a tubular shaft, an approximation assembly, and a seal. The approximation assembly includes a lead screw, a tubular member, a cable, and a trocar assembly. The tubular member threadably engages the lead screw such that rotation of the lead screw causes axial displacement of the tubular member. The cable extends within the tubular shaft and is coupled to the tubular member for concomitant displacement with the tubular member. The trocar assembly extends from the cable. The trocar assembly is coupled to the anvil assembly such that axial displacement of the tubular member transitions the anvil assembly between a spaced apart configuration and an approximated configuration. The seal provides a fluid-tight seal such that the adapter assembly includes a sealed portion and an unsealed portion. The lead screw is disposed within the sealed portion.
