[0002] Cyst is a disease with a high incidence in my country. Take thyroid cyst as an example. Thyroid cyst refers to a cyst containing fluid found in the thyroid gland. The lump is round, with a diameter of 2 to 5 cm, smooth, generally painless or slightly painful, and moves up and down with swallowing. Most are single nodules, and multiple nodules are rare. When the pressure inside the thyroid cyst is not high, the texture is relatively soft. If there is more fluid, the texture will be tougher. Thyroid cysts usually have no symptoms unless the cyst is very large or there is bleeding in the cyst, which may cause some compression symptoms such as pain, difficulty swallowing, difficulty breathing, hoarseness, etc.

[0003] In some treatment processes, puncture drainage and drug injection treatment methods are used. With this treatment method, the cyst needs to be punctured with a puncture needle to aspirate the cyst fluid. After aspiration, if drug injection is needed, it is necessary to puncture again and then inject the drug, which is inconvenient to use.

[0004] In summary, in the prior art, when the treatment of thyroid cysts requires fluid extraction and infusion treatment, repeated puncture treatment is required, which leads to inconvenience in treatment. Utility Model Content
