ABSTRACT:
An assembly to facilitate endoscopic surgery comprises an endoscopic dual head needle holder, a needle transporter, a needle guide forceps and an endoscopic suture with a terminal loop. The assembly is utilized in a unique process wherein the tissue to be sutured is grasped by the needle guide forceps and the needle inserted into and through the tissue with the assembly. The needle is inserted into a body cavity with a transporter, a first needle holder is advanced to the appropriate level and the needle transferred to the first needle holder. The needle is then passed through the tissue to a second needle holder and then back to the first needle holder. The needle is then passed through the suture loop securing the thread on the tissues. Continuous suturing is then achieved by successive passage of the needle by the first needle holder through the tissues by the first needle holder, retrieval of the needle by the second needle holder and passage of it back to the first needle holder. Continuous suturing is therefore accomplished at a fast, safe and effective pace. Finally, the needle is transferred to a transport instrument, the thread cut and the needle removed from the cavity by the transporter.
