Abstract
An adaptor cap assembly is provided for a trocar, consisting of a base which contains an opening which is the same size as the opening of the trocar cannula handle. There is also a cap integrally attached to the base which contains a gasketing assembly wherein the assembly is of a smaller diameter than the diameter of the trocar cannula handle opening as well as the opening in the base of the adaptor cap assembly. This cap is hingedly attached to the base so that it can be flipped by using the thumb either into or out of alignment with the openings of the trocar cannula handle and the base of the adaptor cap assembly. Thus, this mechanism can be used so that a smaller diameter instrument can be placed within a larger diameter opening (with the adaptor cap in place), or, the adaptor cap can be moved out of place so that a larger diameter mechanism can be inserted within the adaptor cap assembly and into the trocar cannula handle, with both the base and the trocar cannula handle having the same size opening.
