Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an auxiliary device for aspirating thyroid cyst fluid. Background Art

[0002] A thyroid cyst refers to a sac-like object containing fluid found in the thyroid gland. Existing treatment methods mainly include: surgical resection, puncture and fluid extraction, drug sclerosis, radiofrequency ablation, etc. Among them, the puncture and fluid extraction method is the most common and simple to operate. A syringe is used to insert the puncture needle into the cyst position, and the cyst fluid is drawn into the syringe by pulling the piston handle. During the fluid extraction process, as the cyst fluid in the syringe increases, the difficulty of pulling the piston handle also increases. Therefore, in routine operations, two doctors need to cooperate with each other to complete it. If the operation is unstable, it is easy to cause failure of the puncture treatment, and a second puncture and fluid extraction will be required, which is also easy to cause secondary harm to the patient. Therefore, there is a need for an auxiliary device for thyroid cyst fluid aspiration. Utility Model Content
