Problems solved by technology

[0004] For thyroid nodules and cysts, puncture must be used to obtain pathological specimens for diagnosis, or to extract cystic fluid for treatment. Therefore, thyroid puncture needles are an important medical device. Among the existing thyroid puncture needles, thyroid The puncture needle can only be extracted once, and the cystic fluid cannot be successfully extracted due to insufficient negative pressure or insufficient fluid extraction. When the fluid in the thyroid cyst is viscous or solid nodular mass, it is not appropriate to use the thyroid puncture needle. It is easy to take out, which brings great inconvenience to diagnosis and disease treatment

Embodiment 1

[0019] The thyroid puncture device of this embodiment includes a syringe 2 connected with a needle body 1 at the front, a needle core 3 is installed in the needle body 1, an opening is provided on one side of the needle body 1, and a cover plate 10 is movably connected to the opening. When using the needle core 3 to extract liquid, open the cover plate 10, socket the needle core 3 on the front end of the syringe 2, and close the cover plate to perform extraction.

[0020] A one-way valve 4 is provided at the inlet of the syringe 2 to avoid liquid backflow, and a push handle 5 is provided inside the syringe 2, and the end of the push handle 5 is an airfoil structure, which is convenient for pushing and pulling by medical personnel; one side of the syringe 2 is fixedly installed with a piston The negative pressure tube 6 of 7, when the negative pressure tube 6 is not needed, the piston 7 plugs the opening of the negative pressure tube 6, and when negative pressure assistance is n...

Abstract

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.
