PROBLEM TO BE SOLVED: To provide a biopsy needle allowing a needle part and a driving part to be separated and disposed of separately. SOLUTION: This biopsy needle has an inner needle 1 with a cutout part formed at the tip part, and a hollow outer needle 2 into which the inner needle 1 is inserted. A hub 11 is rigidly fixed to the rear end of the outer needle 2, and the hub 11 is detachably fitted to a moving piece 12. A notch 1b is formed at the inner needle 1, and if the outer needle 2 is slightly pulled out to bend the inner needle 1, the inner needle 1 is ruptured from the notch 1b part. |
