Abstract:
1. A stability assembly for a trocar system comprising: a stability member having a generally conical outer surface and a lumen extending through the stability member; a base positioned at least partially within the lumen of the stability member, the base having an outer surface and an inner surface defined by a passage extending therethrough, the passage adapted to receive a cannula therethrough, and the inner surface including at least one constriction; and a cannula retention member positioned at least partially within the passage of the base and is rotatably coupled to the base, wherein the cannula retention member is rotatable between a first position in which the passage of the base and the retention member define a first inner diameter, and a second position in which a portion of the retention member is advanced over the constriction such that the passage of the base and the retention member define a second inner diameter smaller than the first inner diameter further comprising a latch mechanism configured to selectively retain the cannula retention member in the second position, the latch mechanism comprising:
