Rotational latching system for a trocar

摘要

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. The trocar housing also includes a rotary latch mechanism selectively coupling the first housing member and the second housing member. The rotary latch mechanism includes a latching member which rotates relative to the first and second housing members about a longitudinal axis of the housing member for selectively coupling the first and second housing members.
