Thyroid nodules are a thyroid disease with a high incidence, and are particularly closely related to thyroid cancer. Thyroid nodules are classified into benign nodules and malignant nodules, wherein malignant nodules are more occult and easily misdiagnosed or not easily found in the early stages. Clinically, tissue cells at the nodule site are extracted for a corresponding pathological examination using thyropuncture biopsy (Fine Needle Aspiration Biopsy, FNAB). A typical puncturing process is as follows, puncturing is carried out on a suspicious lesion site by adopting a mode of manually puncturing a fine needle under ultrasonic guidance, and when a needle point reaches the center of a nodule, the needle point is lifted and inserted back and forth in different needle tracks for a plurality of times so as to extract tissue fluid which is enough for sample preparation and carry out smear analysis. FNAB has the characteristics of being minimally invasive, convenient, economical and the like due to high sensitivity, strong controllability and strong specificity, and has become a currently accepted conventional thyroid nodule examination means. FNAB is susceptible to levels of puncture, smear, slide, and pathologist review of specimens. In particular, current puncturing techniques have their own drawbacks: firstly, when the needle reaches the center of the nodule, the lifting and inserting action is manually finished by a doctor, the accuracy of the hand action of the doctor is required to be high, the lifting and inserting depth is required to be strictly controlled, and particularly for the tiny nodule, if the target tissue cells are ensured to be effectively extracted, the interference of other tissue fluids is eliminated, and the method has high challenges to the doctor; secondly, because of the manual mode, the lifting and inserting speed is lower, and for complex focus, the puncturing consumes longer time, so that the efficiency is low, the puncturing depth is different, and the accurate quantification cannot be realized; finally, the hands of doctors are easy to fatigue, the problems of action coordination such as shaking and the like are easy to occur, the puncture effect is affected, and extra injury and pain can be brought to patients.
