PROBLEM TO BE SOLVED: To provide a medical needle capable of reliably preventing a needle body from being projected again from a protector after the needle body is stored.SOLUTION: A medical needle 10 includes: a needle body 12 having a needle tip 12a at the distal end; a shaft 24 provided on the proximal end of the needle body 12; a storage cylinder 16 surrounding the shaft 24, on the inner side of which the shaft 24 is disposed so as to be displaced in an axial direction; and a lock member 18 fixed to the storage cylinder 16 and provided with an engaging part 62 which can be engaged with the shaft 24. The shaft 24 can be slid, with respect to the storage cylinder 16, from a first position at which the distal end of the needle body 12 is projected from the storage cylinder 16 for a prescribed length to a second position at which the distal end of the needle body 12 is stored inside the storage cylinder 16. When the shaft 24 is moved to the second position, the engaging part 62 of the lock member 18 is engaged with the shaft 24, and thus, the shaft 24 is locked at the second position with respect to the storage cylinder 16. |
