New Electric Thyroid Puncture Device with Negative Pressure

technical field

The utility model relates to the field of medical instruments, in particular to a novel electric thyroid puncture device with negative pressure.

Background technique

Clinically, in the process of diagnosing certain thyroid diseases, it is often necessary to use puncture to perform a biopsy of the thyroid to be punctured under the guidance of ultrasound, so as to obtain pathological specimens for diagnosis. At present, various types of puncture needles are widely used at home and abroad for puncture biopsy, or directly hold a syringe to make the puncture needle enter the mass through the skin, and then repeatedly advance and retreat in the mass, supplemented by negative pressure suction to obtain the puncture material for cytological analysis use. Among them, thyroid biopsy is divided into coarse needle aspiration and fine needle aspiration. Fine-needle aspiration biopsy has less damage to tissue, less bleeding, safety and quickness, and less chance of infection. It has high sensitivity and specificity in cytological diagnosis, and has been widely used in clinical practice. Studies have shown that fine-needle aspiration biopsy also has certain drawbacks. For example, for some deep or small parts to be tested, it is difficult to puncture the lesions with ultrasound-guided fine-needle aspiration, which requires high puncture techniques for the operator and requires professional expertise. It is difficult to perform histological examination of the obtained material.
