Abstract: Provided is an ultrasound endoscope capable of achieving both improvement of the kink resistance of a forceps tube in a bending part and improvement of electromagnetic wave shieldability in a distal end hard part.
A forceps tube is configured such that a metal element wire is wound around a tube bending part that is disposed inside a bending part, and a tube distal end part including an opening portion facing region facing an opening portion of a shield ring is formed of a material that is hardly influenced by electromagnetic waves. The tube distal end part is configured of only the forceps tube. That is, the metal element wire that is influenced by electromagnetic waves is not wound around the tube distal end part, and resin, such as fluororubber or silicon rubber, to be hardly influenced by electromagnetic waves is exposed from the opening portion facing region.

Abstract: Provided is an ultrasonic endoscope with which it is possible to improve a brush cleanability of a communication path. A distal end portion (44) of an ultrasonic endoscope (10) includes: a balloon attachment portion (152) for attachably and detachably attaching a balloon (60) to the distal end portion (44), the balloon attachment portion (152) including a first balloon groove (154) that is provided over an outer periphery of the distal end portion at least on a proximal end side of an ultrasound oscillator (92); and a communication path (90) for supply or suction of a fluid with respect to an inner space of the balloon (60). An entrance and exit way (91) of the communication path (90) is formed to be diagonally inclined with respect to a longitudinal axis of an insertion portion (12). The first balloon groove (154) includes a shallow groove portion (158) that is formed to have a groove depth smaller than other portions in a circumferential direction of the distal end portion (44), and the entrance and exit way (91) of the communication path (90) is provided in an internal region of the distal end portion (44) where the shallow groove portion (158) is formed.
