A modular trocar system which includes an obturator assembly, and a cannula assembly defining a longitudinal passageway therethrough configured and dimensioned to slidably receive the obturator assembly, the cannula assembly including a housing which includes a valve assembly and a first mating portion, and a cannula defining a passageway of a predetermined dimension therethrough, the cannula and housing movable alternately between a spaced apart relative orientation and an attached orientation wherein the first and second mating portions are engaged.

Modular trocar system and methods and assembly

A modular trocar system is provided which includes an obturator assembly, and a cannula assembly defining a longitudinal passageway therethrough configured and dimensioned to slidably receive the obturator assembly, the cannula assembly including a housing which includes a valve assembly and a first mating portion, and a cannula defining a passageway of a predetermined dimension therethrough, the cannula including a second mating portion disposed thereon, the cannula and housing movable alternately between a spaced apart relative orientation and an attached orientation wherein the first and second mating portions are engaged. A method of assembly is also provided and includes the steps of connecting a shield member of a first predetermined configuration and dimension to a first housing section, attaching a knife blade assembly of a second predetermined configuration and dimension to the first housing section with a single motion wherein the attachment permits rotation of the knife blade relative to the first housing section, and attaching the first housing section to a second housing section with a quick connect mechanism which includes first and second mating portions such that the first and second housing sections are movable from a spaced apart position to a connected position in a single motion.
