Abstract
A trocar assembly includes a seal assembly that maintains insufflation pressure when sized seal cartridges are removed and replaced. The trocar assembly includes a housing that defines a working chamber, and a cannula distally extends from the housing and defines a lumen that communicates with the working chamber. The seal cartridge is arranged within the working chamber, and may include one or both of a proximal seal assembly and a distal seal assembly arranged distally from the proximal seal assembly, and may further include a bushing extending distally from a distal end of the seal cartridge and into the lumen. A tertiary seal may also be positioned within the working chamber distal to the seal cartridge, such that the bushing extends through the tertiary seal when the seal cartridge is received within the working chamber.
