<P>PROBLEM TO BE SOLVED: To provide a hemostatic apparatus simultaneously stopping bleeding at a plurality of sites by utilizing a characteristic of a shape memory material which varies its shape according to a temperature. <P>SOLUTION: The shape memory material in which a shape memory function of changing a low-temperature-side length L<SB>1</SB>to a high-temperature-side length L<SB>2</SB>after phase transformation is generated is used for a needle support part 11, and a plurality of hemostatic needles 12 are fixed to the needle support part 11. When the hemostatic needles 12 are inserted to blood vessels inside of an internal organ and when this comb hemostatic apparatus 10 is heated by heat of internal organ, a plurality of blood vessels are batch pressed and blood-stopped by the hemostatic needles 12 whose adjacent intervals are narrowed from P<SB>1</SB>to P<SB>2</SB>. Hemostatic needle in which a shape memory function of releasing a twisted state on the low-temperature-side by the phase transformation is generated can be used. <P>COPYRIGHT: (C)2004,JPO |
