    摘要： An instrument for taking a tissue sample is provided with a tissue receiving element (2) that has a distal end (4) and partly consists of a helix (6) comprising the distal end and has an outer surface (8), an inner surface (7), and a central longitudinal axis (X-X'). The helix has a zone (5) whereby for each point of a first intersecting line of the outer surface (8) and a plane of which the central longitudinal axis (X-X') forms part the distance (d) from the outer surface (8) to the longitudinal axis (X-X') is less than the distance (d) between the outer surface (8) and the longitudinal axis (X-X') on every more proximally located point, and whereby for each point of a second intersecting line of the inner surface (7) and an aforementioned plane, the distance (d') from the inner surface (7) to the longitudinal axis (X-X') is greater than the distance (d') from the inner surface (7) to the longitudinal axis (X-X') on every more proximally located point.

    摘要： A distal end component 1 includes: a transparent resin outer layer portion 2 that is made of a transparent first resin member and configures a surface of a distal end portion of an insertion section 11; an internal structure portion 3 that is made of a second resin member different from the first resin member and is provided in tight contact with an inner surface 2i of the transparent resin outer layer portion 2; a plurality of component fixing holes 30, 40A, 40B, and 50 in which distal-end-side end portions of components 9a, 5, and 6 provided in the insertion section 11 are respectively disposed, the component fixing holes 30, 40A, 40B, and 50 being provided in the internal structure portion 3; and lens sections 2a, 2b, and 2c provided in the transparent resin outer layer portion 2, the lens sections 2a, 2b, and 2c respectively facing distal end surfaces 5f of illumination optical sections 5 and a distal end surface 6f of an observation optical section 6, the illumination optical sections 5 and the observation optical section 6 being disposed in the insertion section 11, the illumination optical sections 5 having distal-end-side end portions that are respectively disposed in the illumination optics holes 40A and 40B, and the observation optical section 6 having a distal-end-side end portion that is disposed in the observation optics hole 50.
