PROBLEM TO BE SOLVED: To provide a puncture device which reduces a burden on a patient, exhibits high safety of the patient, and is capable of easily embedding an indwelling object for supporting a biological tissue into a living body.SOLUTION: A puncture device 1 comprises curved puncture needles 71 and 81 which are arranged so that the base ends of the puncture needles 71, 81 do not interfere with each other, in an initial state before puncture is performed. Then, the puncture needles 71 and 81 are turned together to the distal end side to cause the distal end parts of the puncture needles 71 and 81 to engage with each other. The respective distal ends of the puncture needles 71 and 81 move within nearly the same plane. The puncture needles 71 and 81 are each formed spirally. |
