Abstract: An endoscope button for an endoscope including a cylinder communicating with tubes includes: a first unit and a second unit that are attachable and detachable with respect to a fitting part fixed to the cylinder, and that are separable from each other in a state being removed from the fitting part. The first unit has a cylindrical shape, and includes a cylindrical member that is attachable and detachable with respect to the fitting part. The second unit includes: a fixing member that is inserted inside the cylindrical member in a state in which the endoscope button is attached to the fitting part, and is fixed to the cylindrical member; and a first movable member that is installed movably with respect to the fixing member, and that is movable back and forth inside the cylinder in the state in which the endoscope button is attached to the fitting part.

Abstract: An ultrasound endoscope, includes: an insertion portion configured to be inserted into a subject, acquire an optical subject image, and transmit and receive ultrasound; an ultrasound transducer configured to emit the ultrasound in a direction perpendicular to a longitudinal direction of the insertion portion, and perform scanning in a circumferential direction of an axis parallel to the longitudinal direction; a forward field optical portion that is provided at a distal end of the insertion portion in the longitudinal direction, the distal end being where observation light coming from a forward field enters; and a side field optical portion that is provided at a distal end side of the insertion portion in the longitudinal direction and is where observation light from a side field including a part of a scan plane of the ultrasound transducer enters, the side field being a field in a direction perpendicular to the longitudinal direction.

Abstract: An intracoelomic mobile body comprising: a capsule body which has a body to be rotated and can be introduced into the human body; and a rotation drive unit which has a rotation shaft for freely rotating the body to be rotated back and forth. The rotation drive unit is arranged in the capsule body in such a way that a first line obtained by linking the positions of center of gravity of cross-sections formed up to a limit of the formation when the capsule body is cut along a plane perpendicular to the rotation shaft does not overlap a second line obtained by extending the rotation shaft as the same line.

Abstract: A magnetic fluid detection device includes an exciting unit for generating an exciting magnetic field to excite a magnetic fluid staying in a subject, a coil for detecting a local distortion in magnetic field distribution occurring due to the magnetic fluid excited with the exciting magnetic field generated by the exciting unit, and a control unit for signal-processing an output from the coil and informing the resultant signal magnitude.
