[0046] The working principle of the present invention is: a thyroid puncture positioning device, when in use, firstly, the puncture medical needle 32 needs to be placed in the plastic splint 9, so that the upper circle 34 is located above the plastic splint 9, and the lower circle 33 is located below the plastic splint 9, then the electric telescopic rod 28 is started, and its output end drives the magnetic suction head 30 and the magnetic suction piston 31 to be magnetically attracted, and then the T-shaped plate 26 is pulled outward, and the T-shaped plate 26 drives the spring 25 to stretch the side length, at this time, the limiting state of the T-shaped plate 26 on the slot 23 is released, and the operator rotates the pressing plate 6, and the pressing plate 6 rotates After the U-shaped rotating plate 22 is driven to rotate together, the patient lies flat on the bed with his neck against the soft pad 2. At this time, the pressing plate 6 is rotated to drive the U-shaped rotating plate 22 to reset, and the T-shaped plate 26 is reinserted into the slot 23 to keep it stable. Then the degree of bending of the patient's neck can be adjusted. At this time, the second screw rod 13 is rotated to drive the triangular block 11 to slide, and the height of the trapezoidal plate 16 and the protrusion 18 in the slide cylinder 17 is changed. The height change of the trapezoidal plate 16 drives the height change of the lifting adjustment plate 14. After the lifting adjustment plate 14 contacts the inner top wall of the neck pillow 1, the lifting adjustment plate 14 changes. The cervical pillow 1 and the degree of neck bending are used to adjust the patient's neck bending. At this time, the first reduction motor 19 is started, and the output end of the first reduction motor 19 drives the first screw rod 20 to rotate. The rotation of the first screw rod 20 drives the U-shaped slide plate 21 and the pressing plate 6 to slide as a whole for height adjustment. When the height of the pressing plate 6 is appropriate, the second reduction motor 35 is started, and the output end of the second reduction motor 35 drives the first gear 36 to rotate. The rotation of the first gear 36 drives the arc rack 37 to slide on the surface of the pressing plate 6 for position adjustment. The movement of the arc rack 37 drives the plastic splint 9 to adjust the position. At this time, the angle of the puncture medical needle 32 located in the plastic splint 9 is changed, and the angle is judged by the indication of the angle scale line 8 through the indicator head 29. The puncture medical needle 32 performs the puncture operation as the height of the pressing plate 6 decreases. When sampling, the electric telescopic rod 28 is started, and the output end of the electric telescopic rod 28 drives the magnetic suction head 30 to move together with the magnetic suction piston 31, and the magnetic suction piston 31 rises to extract the sampling operation. With the above structure, the posture of the neck can be maintained, which is convenient and accurate for puncture positioning treatment.
