Ultrasound-guided percutaneous puncture of thyroid nodules using a cytological biopsy instrument for pathologic examination is the gold standard for identifying benign and malignant thyroid nodules. Leading the general trend of domestic substitution of imports, Leapmed has independently developed and produced domestic Cytological Biopsy Instruments dedicated for thyroid puncture since 2015. Multiple specifications, including 22G, 23G and 25G, are available. Moreover, the Thyroid Nodule Biopsy Kit (consisting of an ultrasonic probe sleeve, and sterile ultrasound gels, etc.) has been launched, to serve as a one-stop solution for cytological biopsy of thyroid nodules.
