Abstract
A trocar housing for a trocar assembly includes a first housing member selectively coupled to a second housing member, wherein the first and second housing members include aligned apertures shaped and dimensioned for passage of an instrument therethrough. A button latch mechanism selectively couples the first housing member and the second housing member, the button latch mechanism including a latching member which slides about a central axis of the first and second housing members for selectively coupling the first and second housing members.
