Abstract
A modular trocar assembly having a cannula, a passive valve seal assembly and an instrument seal assembly all releasably joined to define a central axial bore, where the passive valve seal assembly contains a valve seal which prevents passage of gas through the trocar assembly into the atmosphere when no instrument is inserted but which opens to allow for insertion of an instrument, and where the instrument seal assembly contains an instrument reducer seal which prevents passage of gas through the trocar assembly into the atmosphere when an instrument is inserted through the valve seal. The passive valve seal assembly and the instrument seal assembly are preferably composed of plastic so as to be disposable, while the cannula is preferably composed of a sterilizable material to enable reuse.
