With the continuous improvement of examination means and methods, the accuracy of diagnosis has gradually increased, but there are still a large number of tumors that do not have typical imaging characteristics and are difficult to diagnose. Correct diagnosis requires a combination of clinical, imaging and pathological analysis. Among them, pathological diagnosis plays a key role in the choice of treatment plan, and puncture biopsy is the main way to obtain pathological diagnosis.

[0003] For example, publication number CN216495410U discloses a thyroid double-sheath puncture cell biopsy needle device, which relates to the field of medical device technology.

After wiping, the first locking plate 2 and the second locking plate 3 are continued to be moved downward to make the bottom of the buffer pad 4 fit with the patient's skin surface. By using the arc groove 23, the air inside the arc groove 23 is discharged by pressing the buffer pad 4 to form a negative pressure, which can improve the fitting stability of the buffer pad 4. Finally, the thyroid puncture biopsy device body 1 can be used to sample thyroid cells.
