Claims8
A trocar housing for a trocar assembly, comprising:
- 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 coupling the first housing member and the second housing member, the button latch mechanism including:
- a resilient latching member positioned within an annular groove formed in the second housing member, the latching member circumferentially sliding in the annular groove about a central axis of the first and second housing members for selectively coupling the first and second housing members, the latching member including a detainment pin;
- at least one arm downwardly extending from the first housing member;
- and an aperture formed in the second housing member through which the arm is passed to engage the detainment pin for engagement of the first and second housing members, the aperture being only slightly larger than the arm to prevent bending of the arm by the interaction of the at least one arm with the detainment pin.
