<P>PROBLEM TO BE SOLVED: To provide a puncture needle capable of easily adjusting the puncture angle. <P>SOLUTION: The puncture needle includes a leading end part 114 equipped with a needle tip 112, a hollow needle part 110 having the needle part lumen 118 communicating with the needle tip 112 and the stylet 120 freely sliding to be inserted in the needle part lumen 118. The needle part 110 is arranged at a position separated from the needle tip 112 and has a flexible part 113 elastically deformed by the puncture load of the needle tip 112. The stylet 120 has reinforcing parts 124A and 124B for obstructing the elastic deformation of the flexible part 113. The reinforcing parts 124A and 124B slide through the needle part lumen 118 to freely support the inner periphery of the flexible part 113. <P>COPYRIGHT: (C)2012,JPO&INPIT |
