Abstract: An endoscope includes an insertion part and an operation part. The operation part is consecutively provided at the insertion part. A bendable portion is provided at a distal end portion of the insertion part so as to be bendable. An operation part-side operation member is provided at a distal end portion of the operation part and has an operation part-side protruding portion. An insertion part-side operation member is provided at a proximal end portion of the insertion part and has an insertion part-side protruding portion and finger rest protruding portions, and the insertion part-side protruding portion and the operation part-side protruding portion indicate a rotational movement position of the insertion part with respect to the operation part.

Abstract: A treatment tool for an endoscope includes a transmitting part that transmits an operation of an operating part to a grip part and a bendable part of a distal end part. The transmitting part has a first transmitting member hat is moved to an operating part side based on the operation of the operating part and closes the grip part and a second transmitting member that is moved to the operating part side based on the operation of the operating part and bends the bendable part. In response to the operation of the operating part, first, the first transmitting member is moved to the operating part side, and the second transmitting member is moved to the operating part side after the start of the movement of the first transmitting member.

Abstract: A treatment tool for an endoscope includes an operating part and a transmitting part that transmits an operation of the operating part to a grip part of a distal end part and a bendable part. The operating part has an operating member that is movable in a first direction and a second direction orthogonal to the first direction. The transmitting part has a first transmitting member that is moved to an operating part side based on an operation of the operating member in the first direction and closes the grip part and a second transmitting member that is moved to the operating part side based on an operation of the operating member in the second direction and bends the bendable part.

Abstract: Provided are a pickup sensor and a biological sensor that are small-sized and can detect micro vibration efficiently and stably with high accuracy. The pickup sensor includes an electroacoustic converter film including: a piezoelectric polymer composite in which piezoelectric particles are dispersed in a viscoelastic matrix that is formed of a polymer material having viscoelasticity at normal temperature; two thin film electrodes that are laminated on opposite surfaces of the piezoelectric polymer composite, respectively; and a protective layer that is laminated on at least one of the two thin film electrodes, in which at least a part of a surface of the electroacoustic converter film is an abutting surface that abuts against a test object, and the thin film electrode on a surface opposite to the abutting surface is grounded.
