[0004] This patent is a puncture needle, which is used as a puncture product as a whole. Although the adjustment function of the needle is provided, in the specific operation, the adjustment of the needle can only be adjusted at a limited angular position, and the adjustment of the needle cannot be realized. The fixed and stable puncture operation, a little carelessness, will cause the change of the puncture point, and the adjustment of the angle after the subcutaneous puncture is extremely difficult, and often needs to be punctured again, so there are certain defects in this prior art

Embodiment Construction
[0021] Such as figure 1 , 2 , 3, 4, 5, and 6, a disposable thyroid puncture device positioning device includes two longitudinal support plates 1, and a horizontal support rod 12 fixedly installed between the bottoms of the two longitudinal support plates 1, the described The two longitudinal support plates 1 are plate-like structures with an arc-shaped notch 3 at the bottom and a semicircular top. Limiting grooves 2 are provided on the two longitudinal supporting plates 1, and the two limiting grooves 2 run through A sliding shaft 7 is installed, and a rotary bearing 4 is installed at the center positions of the two longitudinal support plates 1. The two rotary bearings 4 are sleeved with a rotary shaft 5. The two ends of the sliding shaft 7 on the outside of the two longitudinal support plates 1 are A sliding link 6 is fixedly installed, and the bottoms of the two sliding links 6 are respectively set on the two ends of the rotating shaft 5 outside the two longitudinal suppor...

The invention relates to a disposable thyroid puncture outfit positioning device. Limiting grooves are formed in two longitudinal supporting plates respectively, sliding shafts penetrate through the two limiting grooves, the centers of the two longitudinal supporting plates are provided with rotating bearings respectively, the two rotating bearings sleeve rotating shafts, the two ends of the sliding shafts at the outer sides of the two longitudinal supporting plates are fixedly provided with sliding connecting rods respectively, the bottoms of the two sliding connecting rods sleeve the two ends of the rotating shafts at the outer sides of the two longitudinal supporting plates respectively, one sides of the two longitudinal supporting plates are fixedly provided with a b-ultrasound scanner probe fixator, a sliding support is fixedly connected between the sliding connecting rods and the rotating shafts between the two longitudinal supporting plates, and a puncture outfit sliding clamping groove is movably formed in the sliding support. The disposable thyroid puncture outfit positioning device can stably achieve a supporting effect on a puncture outfit, and achieves stable longitudinal operation of an injector after the puncture angle position is determined, thereby reducing the re-puncture pain of a patient.
Description
technical field [0001] The invention relates to the medical field, in particular to a positioning device for a disposable thyroid puncturer. Background technique [0002] Thyroid biopsy is a procedure used to diagnose nodular thyroid disease. Thyroid fine-needle aspiration biopsy is now established as a highly accurate diagnostic method. In traditional thyroid puncture, it is necessary to use a disposable thyroid puncture device to obtain pathological specimens for diagnosis of thyroid nodules, and it is necessary to use a B-ultrasound probe to determine the specific puncture location. The B-ultrasound probe and disposable puncturer are used to carry out the overall biopsy sampling operation. The disposable puncturer used is mostly a syringe. The needle of the syringe is used to enter the puncture sampling position, and then a certain amount of thyroid nodule sample is extracted. However, in this operation, there are certain defects. The specific performance is as follows:...
