Endoscope system and operation method for endoscope

Abstract

According to the endoscope system of the present invention, when the image pickup device of the first endoscope device detects illumination light irradiated from the illumination device of the second endoscope device, the control device performs control so as to reduce light quantity of the illumination device of the second endoscope device based on the level of luminance signal outputted from the solid state image pickup element of the image pickup device, and when the image pickup device of the second endoscope device detects illumination light irradiated from the illumination device of the first endoscope device, the control device performs control so as to reduce light quantity of the illumination device of the first endoscope device based on the level of luminance signal outputted from the solid state image pickup element of the image pickup device.

1 . An operation method of endoscopes comprising
 a first endoscope device provided with an endoscope and an insertion assisting tool into which an insertion part of the endoscope is inserted and which assists insertion of the insertion part into a body cavity, and   a second endoscope device provided with an endoscope and an insertion assisting tool into which an insertion part of the endoscope is inserted and which assists insertion of the insertion part into a body cavity, comprising the steps of:   inserting the first endoscope device from the mouth of a patient; and   inserting the second endoscope device from the anus of the patient,   wherein treatment is performed by the first endoscope device and the second endoscope device.   
     
     
         2 . The operation method of endoscopes according to  claim 1 ,
 wherein an expandable and contractible first balloon is provided at a tip part of the insertion part of the endoscope of the first endoscope device and a second balloon is provided at a tip part of the insertion assisting tool of the first endoscope device,   wherein an expandable and contractible third balloon is provided at a tip part of the insertion part of the endoscope of the second endoscope device and a fourth balloon is provided at a tip part of the insertion assisting tool of the second endoscope device, and   wherein the insertion parts of the endoscopes are inserted while expanding and contracting the first to fourth balloons.
