Abstract

A dual functioning instrument set, comprising a needle and guide, has not only the capabilities to enter and insufflate the abdominal cavity but also the ability of a suture passer to carry and retrieve suture for closure of the incision sites at the end of the procedure. The needle contains a deployable snare that is used to pass and retrieve suture. The guide is used to repeatedly locate the needle relative to the inner abdominal wall allowing for consistent placement of sutures. For insufflation purposes, obturator tips having different distal structures are provided for shielding the sharp needle tip after insertion through a body wall.
