PROBLEM TO BE SOLVED: To obtain an ultrasonic endoscope that can easily describe a treatment instrument of a flexible line shape in an ultrasonic tomographic image without relying on capability of an operator in the ultrasonic endoscope in which an ultrasonic probe that obtains an ultrasonic tomographic image of an observation region is disposed in an insertion part distal end, and a forceps channel to project the treatment instrument of a flexible line shape in an ultrasonic tomographic image of an ultrasonic probe is opened in the insertion part distal end.SOLUTION: An ultrasonic endoscope makes a forceps channel meander in a plane including an ultrasonic scanning plane of an ultrasonic probe near the opening. |
