<P>PROBLEM TO BE SOLVED: To provide a puncturing needle for an endoscope for which the complete pulling out of a stylet is not required when a texture is suction-sampled by puncturing the puncturing needle into an objective site, and which is excellent in operability and handling properties. <P>SOLUTION: On the rear outer peripheral surface of a site where the distal end member 52 of the pipe-like stylet body 51 is fixed, a cutout section 51a extending in the axial direction by a specified length is installed. When a tissue is suction-sampled by puncturing the needle tube 22 to the target site, the cutout section 51a of the stylet body 51 is exposed from the needle tube 22, and thus, the suction-sampling of the tissue into the stylet body 51 becomes possible. By this way, a troublesomeness that the stylet is completely pulled out at the time of the suction-sampling of the tissue, and attention is paid to the storage place and the storage state can be eliminated, and the inspection period of time can be shortened by improving the operability and the handling properties. <P>COPYRIGHT: (C)2011,JPO&INPIT |
