Accurate intraoperative parathyroid gland recognition method and detection device thereof

Abstract

The invention discloses an accurate intraoperative parathyroid gland recognition method and a detection device thereof. The detection device comprises a No. 22 needle, a 5ML sterile injector, a glassslide, a shell, a digital display angle gauge, a micro stepping motor, a rotating shaft, a gear, a sliding groove, a first clamping groove, a sliding plate, a rack, a first travel switch, a second travel switch, a second clamping groove, a close cover, a first switch, a second switch and a storage battery. The accurate intraoperative parathyroid gland recognition method and the detection device thereof have the advantages that by the angle detection and display device, accuracy of inclined puncture angles can be improved, and follow-up extraction success rate can be increased; by an internal electric pumping mechanism, operation of medical workers is facilitated and high efficiency in pumping is improved; through coordination between multiple clamping grooves and limiting and fixing devices, the detection device can be used with the 5ML sterile injector in the prior art, and an electric mechanism can be reused sterilely; operation burdens of the medical workers are relieved, detectioncost is reduced, and clinical popularization and application are benefited.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a method for accurately identifying parathyroid glands in an operation and a detection device thereof. Background technique [0002] Accurate identification and protection of parathyroid glands is the key to affecting the quality of life of patients with thyroid disease after surgery. However, the parathyroid glands are characterized by their small size, secret location, and many variations, which make it difficult to effectively protect the parathyroid glands during surgery. According to statistics, the incidence rate of temporary hypoparathyroidism in thyroid surgery is 6.9%-46%, and the patients with permanent hypoparathyroidism account for about 0.5%-2%. Commonly used parathyroid localization methods in thyroid surgery include methylene blue staining, 5-aminolevulinic acid (5-ALA) fluorescence detection, 99mTc-MIBI imaging, lymph node tracer, optical coherence tomogr...

Problems solved by technology

[0003] According to the above, although a variety of positioning methods in the current clinical technology can reduce parathyroid damage, there are still false positives and false negatives, the sensitivity needs to be improved and the operation is complicated. In view of the above defects, it is necessary to design intraoperative parathyroid Accurate gland recognition method and detection device
