Microscopic needle

The utility model discloses a microscopic needle which comprises a tube body part and a needle tip part, the tube body part is of a hollow structure, the needle tip part is connected to one end of the tube body part, the needle tip part and the tube body part are integrally formed parts, and the end face of one end, far away from the tube body part, of the needle tip part is a plane or an arc-shaped surface. Due to the fact that the microscopic needle is a plastic piece, the microscopic needle has certain flexibility, the microscopic needle is not prone to being broken in the storage process or the use process, the service life of the microscopic needle is prolonged, the phenomenon that in the actual use process, the needle tip portion is broken or the fallopian tube wall is punctured, and consequently an experiment fails is not prone to occurring, and the experiment efficiency is improved. The experiment difficulty is reduced; the end face of one end, far away from the tube body part, of the needle tip part
