Thyroid puncture device

The invention relates to a thyroid puncture device, and belongs to the technical field of medical tool structures. The thyroid puncture device comprises an injector; a needle body in which a needle core is mounted is connected to the front of the injector; an one-way valve is arranged at an inlet of the injector; a pushing handle is arranged in the injector; a negative pressure pipe equipped with a piston is fixedly mounted at one side of the injector, and while a fluid storing bottle is mounted at the other side of the injector. According to the thyroid puncture device, the negative pressure pipe is arranged and can generate sufficient negative pressure to absorb cyst fluid, and the absorbed cyst fluid is enough for diagnosis; the liquid storing bottle is arranged, so that cyst fluid can be extracted at a plurality of times; the cyst fluid can be smoothly extracted in case of thick fluid or solid nodule mass; in addition, scales in the fluid storing bottle are able to accurately control the volume of the fluid extracted, which greatly facilitates the diagnosis and treatment of diseases.
