    • A rotational drive sensor 31 which allows a radiation source 10 and a twomensional sensor 20 which are caused to be in one body to turn round a subject 50. An X-ray vessel 13 irradiates X-rays to the subject 50 in a pulsated manner. An X-ray/light conversion element 21 converts an X-ray transmitted image to an optical image. A CCD camera 23 picks up this optical image. An information processing unit 40 reconstructs a three-dimensional pictorial image on the basis of two dimensional pictorial images in plural directions obtained, and a display monitor 46 displays this three-dimensional pictorial image. A controller 39 controls the distance between the X-ray vessel 13 and the X-ray/light conversion element 21 and the focal size of the X-ray vessel 13 on the basis of the size of the subject 50. As a result, it is possible to obtain, in a short time, a three-dimensional pictorial image having less distortion and high resolution in a broad region, and to reduce X-ray exposure quantity to much more degree as compared to the conventional system.

    • A blade sleeve 5 having an annular cutting edge 6 is formed at the distal end of a handle 1. A pressing body 9 is received in the blade sleeve 5 such that the pressing body 9 is allowed to move in the axial direction C. A contact portion 12 is formed at the distal end of the pressing body 9. The contact portion 12 may be located at a retracted position separated inwardly from the cutting edge 6 and a projected position F to which the pressing body 9 is moved from the retracted position, toward the cutting edge 6. When located at the projected position F, the contact portion 12 of the pressing body 9 is projected outward from the cutting edge 6. The pressing body 9 is movable between the retracted position and the projected position F and may be maintained at the retracted position or the projected position F. With the pressing body 9 maintained at the projected position F, a sample SE may be easily removed from the contact portion 12. By projecting from the cutting edge 6 at the projected position F, the contact portion 12 prevents the cutting edge 6 from being damaged, thus protecting the cutting edge 6.
    • 具有环形切割刃6的刀片套筒5形成在手柄1的远端。 按压体9被容纳在刀片套筒5中,使得按压体9能够沿轴向C移动。接触部12形成在按压体9的前端。 接触部分12可以位于从切割边缘6向内分离的缩回位置和按压体9从缩回位置向切割刃6移动的突出位置F. 当位于突出位置F时,按压体9的接触部分12从切割刃6向外突出。 按压体9可以在缩回位置和突出位置F之间移动,并且可以保持在缩回位置或突出位置F.在按压体9保持在投影位置F的情况下,样本SE可以容易地从 接触部分12。 通过从突出位置F处的切削刃6突出,接触部12防止切削刃6受损,从而保护切削刃6。

    • A hand tool includes a holder and a movable head portion to which a blade body is secured. The movable head portion is supported by the holder in a manner movable relative to the holder between an accommodated state Q, in which the movable head portion is accommodated in the holder together with the blade body, and a projected state, in which the blade body is projected from the holder. The orientation N of the blade body in the accommodated state Q and the orientation N of the blade body in the projected state are different from each other. This improves operation of the blade body both in the accommodated state Q and the projected state and reduces the size of a front opening of the holder to provide a compact holder of the hand tool such as a medical edged tool.

    • An excision instrument includes a blade 2 mounted on the back surface of an elastic member 5 provided between gripping extensions 3, and is used by bringing the gripping extensions 3 close to each other to curve the elastic member 5 together with the blade 2 and by putting the convex surface produced on the blade 2 in a portion-to-be-removed. In the top surface of the elastic member 5, a plurality of slits 8, 9 and 10 are provided, and a plurality of projections 11 are provided between the slits 8, 9 and 10 so that contact parts 11a of the projections 11 are brought close to and into contact with each other via the slits 8, 9 and 10 when the elastic member 5 is curved. The contact parts 11a function as a curvature restricting part for restricting the curvature of the elastic member 5 or a flexural rigidity changing part for changing the flexural rigidity of the elastic member 5.
