  Japanese Patent No. 4502757   Utility Model Registration No. 3162161

There is a great difference between the installation of a tubular organ using a conventional endoscope operation training apparatus and the environment of an actual tubular organ. Since an actual tubular organ is bent not only in a straight line but also vertically and horizontally, there is a drawback that it cannot be accurately reproduced with conventional endoscope operation training apparatuses. In the esophageal canal, when examining or treating the diseased part, the actual technique is difficult because the pulsation of the heart on the left side of the esophagus presses the esophagus and deforms the inner wall of the esophageal canal as seen by the operator. In addition, during surgery, it is necessary to rotate the patient's body position in order to perform surgery more safely and properly, and the environment cannot be reproduced, so endoscopic surgery and inspection training in the state of an actual tubular organ cannot be performed. . In addition, as shown in FIG. 3, in the large intestine (16-25), after rotating from the rectum (16) to the upper layer resin network (14) while being rotated into an S shape (17), the back side is advanced toward the head. (20-21) and return to the abdomen again to form the left colonic curve (22). After that, through the formation of the transverse colon (23), it has a complicated form that sinks to the back side again to form the right colon curve (24), sinks into the lower resin network (15) and reaches the cecum (25). It cannot be reproduced by the method supported by both ends of the endoscope operation training device. Since the water in the tubular organ is lost due to spontaneous evaporation as the training time elapses, the electrocautery of the electrosurgical knife is remarkably reduced, and the diseased part cannot be accurately reproduced in the examination or treatment environment.
