Usefulness of a Flexible Port for Natural Orifice Transluminal Endoscopic Surgery by the Transrectal and Transvaginal Routes
(a) The method to carry the apex socket for flexible port insertion out of the body after setting the flexible port: after completing the setting of the flexible port in the abdominal cavity, the apex socket for flexible port insertion is carried out of the body. The carriage is performed by grasping the wire attached to the socket apex with the traction wire which is attached to the flexible port set. The traction wire is inserted into the abdominal cavity after passage through the forceps hole of the transgastric endoscope. The removal of the apex socket from the flexible port is achieved with an instant slight force and by traction for a short distance. The socket separated from the port is carried outside the body from the mouth after passage through the gastric cavity and esophagus. (b) It is possible to set a given number of ports and to carry the sockets outside the body by repeating the procedures as those in Figure 5(a). (c) The sockets for port insertion that were carried outside the body in Figures 5(a) and 5(b): (a) indicates a scene in which the sockets for guidance of the flexible port with the loop wire are removed from the mouth. (b) indicates the sockets for guidance of the flexible ports with the loop wire which were retrieved completely.
