Abstract

A surgical apparatus for introduction of laparoscopic instruments into an anatomical cavity through tissue at an entry site. The apparatus includes a body with a frustoconical-shaped wall. The body defines an interior cavity, an open bottom, and a substantially closed top wall with openings from which a plurality of ports extend upward therefrom. The ports are adapted to receive the laparoscopic instruments for introduction through the interior cavity and open bottom of the body into the anatomical cavity. In the preferred embodiment, the frustoconical-shaped wall of the body is placed through an incision in the umbilicus. In one aspect of the invention, the body is a unitary one-piece molded structure. A reinforcing belt or plate formed from a relatively hard material can be integral to the body, and separately formed port caps each having a septum may be bonded to the ports.
