摘要： A trocar seal system is provided which permits surgical instruments of at least two different diameters to use the same cannula of a trocar while maintaining a sealed body cavity. The seal system mounts to a cannula of the trocar. The seal system includes an upper seal and a lower seal with the upper seal having a larger opening than the lower seal. The lower seal is mounted on a pivotal hinge plate which permits the lower seal to be moved out of the way when a larger diameter surgical instrument is inserted through the upper seal. When a smaller diameter surgical instrument is inserted through the upper seal, the lower seal is not moved out of its path and the lower seal seals about the smaller diameter surgical instrument.
