Abstract: An endoscope is provided in which an attachment/detachment operation of the proximal end of a wire is easily performed to/from an erecting operation mechanism and leakage of current to the outside can be prevented. An endoscope has an operation section 22 provided with an erecting lever, and a movable member 96 that moves in association with an operation of the erecting lever. The movable member 96 is arranged to be exposed to the outside of the operation section 22. A wire 60 is, at a distal end side thereof, coupled to an erecting base, and, at a proximal end side thereof, coupled to an attachment member 98 that is attachable to or detachable from the movable member 96 by a one-touch operation. The wire 60 includes a wire body 60A, and an insulating coat 60B coating a wire exposure region L.

Abstract: In an ultrasound endoscope system and a method of operating an ultrasound endoscope system of the invention, an ultrasound image recognition unit learns at least one of a relationship between an ultrasound image for learning and a name of an organ displayed in the ultrasound image for learning or a relationship between the ultrasound image for learning and a position of a distal end portion of an ultrasound endoscope at the time of imaging of the ultrasound image for learning, on a plurality of ultrasound images for learning in advance. The ultrasound image recognition unit recognizes at least one of the name of the organ displayed in the ultrasound image for diagnosis or the position of the distal end portion of the ultrasound endoscope from the ultrasound image for diagnosis based on a learning result, and a display controller displays at least one of the name of the organ or the position of the distal end portion of the ultrasound endoscope, on a monitor.

Abstract: An endoscope includes a standing base in a tip portion body, an operation wire of which a tip side is connected to the standing base, and a stretchable coating member that covers the operation wire along an extending direction of the operation wire and so as to allow the operation wire to be relatively movable over the entire region from a connection portion between the standing base and the operation wire to an operation wire-guide passage. A tip of the coating member and the standing base are liquid-tightly fixed to each other, and a base end of the coating member and the operation wire-guide passage are liquid-tightly fixed to each other, and the coating member is disposed at a position where a moving path of the coating member and a moving path of a treatment tool led from a treatment tool-guide passage do not interfere with each other.
