ILLUMINATION SUCTION INJECTION EXCLUSION OUTER CYLINDER FOR ENDOSCOPIC SURGERY FORCEPS

摘要

PROBLEM TO BE SOLVED: To provide an illumination suction injection exclusion outer cylinder capable of accurately holding blood vessels with a target lesion by attaching the outer cylinder to usually used forceps when an endoscopic surgery is performed with a laparoscope or thoracoscope or the like, disposing the outer cylinder behind the tissue and illuminating the blood vessels of the an organ (such as stomach, large intestine, small intestine, and esophagus) with the lesion to be resected so that the blood vessels of the tissue can be seen through, capable of safely resecting the target lesion and reducing the resection time by having a suction function for sucking bleeding and functions for injecting physiological saline for cleaning the tissue and excluding and avoiding the tissue at the same time.;SOLUTION: When the endoscopic surgery using the laparoscope or thoracoscope, etc. is performed, the outer cylinder 1 is attached to the usually used forceps from an insertion port of the laparoscope or thoracoscope, and inserted into the abdominal cavity or thoracic cavity. The outer cylinder is disposed behind the target organ and light is emitted from light emission parts 6 and 7 to see through the blood vessels, so that the position of the blood vessels can be accurately recognized. Because of the functions for suction, injection and exclusion of the outer cylinder, the endoscopic surgery can be safely performed.;COPYRIGHT: (C)2013,JPO&INPIT
