Multi-carrier interventional needle

The utility model belongs to the technical field of medical instruments, and particularly relates to a multi-carrier interventional needle which comprises a main body and a needle body. After the hole is formed in the outer side of one end of the needle body and the push ring is arranged on the outer side of the hole in a sleeving mode, the limiting pin is pressed downwards to enable the positioning clamping block to be connected into the limiting clamping groove in the lower end in a clamped mode, the elastic blocking block can be driven to be connected into the needle body in a clamped mode to block the hole, and through the structure, the limiting pin can be conveniently taken out upwards to remove blocking and apply carrier particles; the overall working efficiency is improved, and meanwhile, the external push ring and the limiting pin can be detached and recycled; after the sliding block is installed in the sliding way in a sliding mode and the push ring is moved out, the feeding pipe can automatically s
