ABSTRACT:
An apparatus may serve as a surgical portal for the reception of surgical instruments for use in laparoscopic or similar surgery. The apparatus may include inner and outer tubular elongate members adapted for a longitudinal translation relative to one another to effect a length adjustment of the apparatus. An interface between the two elongate members includes a helical thread providing a mechanism for the translation of the elongate members, and indentations in one of the members provides a locking mechanism for affixing the length.
