A laparoscopic instrument for forming an incision in a body cavity, insufflating the body cavity with gas, and suturing the incision at the completion of the surgery includes a set of jaws at the distal end of the Veress needle or cannula. The jaws are pivoted to one another for motion between an open position or a closed position in which they may be used to grasp a suture in the body cavity for removal from the cavity for knotting. A push mechanism at the proximal end of the instrument moves the jaws between their open and closed position on successive actuations of a pushbutton and retains them in that state until the next push. An illumination source is provided for the distal end of the instrument to provide illumination through the walls of the body cavity so that the surgeon can determine the degree of penetration of the instrument into the body cavity and can identify any major arteries which should be avoided in the formation of other laparoscopic openings.

In a device for use in laparoscopic surgery adapted to form an incision in a body cavity and inflate the cavity with gas passed through the incision, the improvement comprising an elongated member extending through the device from the proximal to the distal end and having a rounded distal end and a slot formed in the member adjacent to the end, the slot having tapered sides with a maximum width at the outer surface of the member and a minimum width at the interior end, with the slot oriented in the general direction of the proximal end, the slot being adapted to capture a length of suture thread for withdrawal through the incision.
