Abstract: There is provided an endoscope apparatus which can notify an operator whether or not a forceps elevator is in a reclined state by simple and inexpensive means. The endoscope includes: a forceps elevator which is erectably provided at the distal end part of an operation part that is provided to the insertion part. The forceps elevator has an erecting motion range from a minimum angular position to a maximum angular position. The operation part includes an index which is shielded by the erecting operation member when the forceps elevator is in the minimum angular position, and which is exposed when the forceps elevator is in a position in which the forceps elevator is erected from the minimum angular position.

Abstract: Provided is an ultrasound endoscope system including an ultrasound endoscope, in which a control circuit controls a transmission circuit such that a transmission of an ultrasound generating transmission signal for generating an ultrasound image and a transmission of a polarization process transmission signal for performing a polarization process are simultaneously performed on a plurality of ultrasound transducers on one side and the plurality of ultrasound transducers on the other side different from each other, and simultaneously performs transmission and reception of an ultrasonic wave and a polarization process on the plurality of ultrasound transducers different from each other.
Accordingly, it is possible to provide an ultrasound endoscope system capable of performing a polarization process on the plurality of ultrasound transducers on the other side, which pause a transmission of ultrasonic waves for acquiring an ultrasound image, by using an existing transmission circuit, simultaneously with a case where the transmission of the ultrasonic wave and a reception of a reflected wave are performed using the plurality of ultrasound transducers on one side to acquire the ultrasound image, and an operation method of an ultrasound endoscope system.-

Abstract: There are provided an ultrasound diagnostic apparatus and an operation method of an ultrasound diagnostic apparatus capable of performing polarization processing during the execution period of ultrasound diagnosis without affecting the image quality of an ultrasound image. In the ultrasound diagnostic apparatus and the operation method of the ultrasound diagnostic apparatus of the invention, a trigger generation circuit generates a trigger for starting polarization processing. After a trigger is given, during the execution period of ultrasound diagnosis, in a non-diagnosis period which is a period other than a period for acquiring an image of each frame and during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, within each frame time in which an image of each frame of an ultrasound image is acquired, a control circuit performs polarization processing on a plurality of ultrasound transducers.

Abstract: In an ultrasound diagnostic apparatus and an operation method of the ultrasound diagnostic apparatus of the invention, a control circuit performs polarization processing on a plurality of ultrasound transducers in a non-diagnosis period, during which transmission of ultrasound waves and reception of reflected waves for performing ultrasound diagnosis are not performed, in a case where the cumulative driving time of the plurality of ultrasound transducers for performing the ultrasound diagnosis becomes equal to or longer than a specified time. A transmission circuit generates a first transmission signal having a driving voltage for performing ultrasound diagnosis using a pulse generation circuit in the case of performing the ultrasound diagnosis, and generates a second transmission signal having a polarization voltage for performing polarization processing using the same pulse generation circuit as in the case of generating the first transmission signal in the case of performing the polarization processing.

Abstract: There is provided an endoscope capable of suppressing the degradation of a distal-end-part body over time that is caused by the sandwiching of a treatment tool.
An endoscope includes a distal-end-part body that is provided at a distal end of an insertion unit. The distal-end-part body includes an elevator-housing space-forming wall that forms an elevator-housing space opened in a direction perpendicular to the direction of the longitudinal axis of the insertion unit, a lead-out portion that includes a treatment tool outlet opened into the elevator-housing space, and an elevator that is provided in the elevator-housing space so as to be rotatable about a rotating shaft between a standing position and a fallen position and includes a guide surface guiding a treatment tool. The elevator-housing space-forming wall includes an opening wall portion provided on an opening side of the elevator-housing space. An opposite wall portion, which is opposite to the guide surface in a case where the elevator is in the standing position, of the opening wall portion is made of a material harder than that of all other wall portions other than the opposite wall portion.-
