Abstract

A surgical device for closing an incision created by a trocar or similar surgical device is disclosed. The surgical device comprises a support member within which are disposed a first and second needle positioning means. Each of these means carries a suture needle in retrorse configuration relative to the distal end of the support member. The needles can be retracted or deployed relative to the support member in a plurality of desired positions. In operation, the needles are deployed at a desired distance from the edge of the incision. The surgeon then pulls the device out of the body of the patient, thereby capturing and pulling the needles through first the peritoneum followed by the fascia. Needle capture means are provided which retain and remove the needles after the peritoneum and fascia are sutured, leaving the loose ends of the suture thread which can then be tied off below skin level to close the incision.
