The ultrasonic endoscope includes: an elongated insertion part having a longitudinal axis and a distal end hard portion provided on a distal end side; an ultrasonic transducer that is provided in the distal end hard portion, and transmits and receives an ultrasonic wave; and a supply port that is provided in the distal end hard portion and supplies water into a balloon surrounding the ultrasonic transducer, in which an indicator indicating a position of the supply port in a peripheral direction around the longitudinal axis is provided on a proximal end side of the insertion part with respect to the distal end hard portion.

Ultrasonic endoscope

An endoscope system includes: an endoscope including a side-viewing observation unit that includes a field of view in a lateral direction of an insertion part to be inserted into an object to be observed and a second protruding portion that protrudes from the insertion part and forms a blind spot in the field of view of the side-viewing observation unit; an image acquisition unit that acquires a side-viewing observation image by using the side-viewing observation unit; a monitor that displays the side-viewing observation image; and a display control section that allows at least a part of the blind spot of the side-viewing observation image in which the second protruding portion is shown up not to be displayed, and displays the side-viewing observation image on the monitor.

Endoscope system and method of driving endoscope system

Operability in inserting an insertion part of an endoscope into a body cavity using an insertion assisting tool is improved. In an insertion assisting tool, a sidewall portion of a tube main bodythrough which an insertion partof an endoscopeis passed is provided with a sidewall opening parthaving a size in which the insertion partcan pass through. A distal end side of the sidewall opening partis provided with a guiding valve, and the insertion partis guided by the guiding valveto be easily fed from the sidewall opening part. The guiding valveis swingably supported, and when the insertion partis fed from a distal end opening partof the tube main body, allowing the parallel state of being substantially parallel to an axial direction of the insertion partand passing the insertion partto a distal end opening partside are enabled.
