Problems solved by technology

The puncture needle method currently used in puncture surgery repeatedly punctures thyroid tissue and uses the principle of siphon to remove a small amount of thyroid cell tissue. The disadvantage is that less tissue is taken out, the accuracy rate is about 90%, and the operation is more troublesome.

Abstract

The thyroid puncture device comprises a puncture needle, a negative pressure suction needle tube, a driving device and a shell. The tip of the puncture needle is blocked, and a cutting hole is formed in the puncture needle close to the tip; the driving device comprises a first driving motor, a first speed reducer, a first transmission mechanism, a second driving motor, a second speed reducer and a second transmission mechanism which are arranged in the shell, the first transmission mechanism is connected with the first driving motor through the first speed reducer, the second transmission mechanism is connected with the second driving motor through the second speed reducer, and a control device is arranged in the shell. The thyroid tissue is cut by rotating the puncture needle and utilizing the cutting hole, and is sucked by the negative pressure suction device, so that the thyroid tissue can be sufficiently and quickly obtained, repeated puncture is not needed, the pain of a patient is reduced, electric work is realized, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a thyroid puncture device. Background technique [0002] Thyroid puncture is a method for diagnosing nodular thyroid disease. If the nodule is large, puncture can be performed directly, that is, after the puncture doctor locates, the tissue cells in the nodule are extracted with a fine puncture needle, and the corresponding cells are extracted. If the nodule is small or deep, it needs to be punctured under the guidance of B-ultrasound, and the tissue cells in the nodule are extracted for corresponding examination. At present, the puncture needle type used in puncture surgery removes a small amount of thyroid cell tissue by repeatedly puncturing the thyroid tissue and using the siphon principle. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the defects of the above technology and provide a thyroid puncture device....
