Ultrasound-assisted positioning of chin bard gun needle biopsy method

Needle biopsy device is mainly used in two situations. The first is breast ultrasound that indicates BI-RADS classification of four or more types of lesions, but does not touch the space-occupying lesions and needs to be used when biopsy is required; the second is palpable breast masses , Used when clarifying the nature of the mass. The Bard gun biopsy is first positioned by ultrasound, using a fully automatic biopsy gun, 14G is selected for puncturing the breast mass, and then 3-4 pieces of tissue are taken out for pathology. Advantages include better accuracy, 0.3-0.5cm living tissue can be removed locally, which is more than fine needle puncture; less trauma, only a small 0.3cm long skin incision is required, which is basically not painful, and the wound does not need to be sutured and checked There is no obvious scar afterwards; it is safe and efficient. Unlike needle biopsy, the hollow needle puncture specimen is taken out in the trocar, which does not cause malignant tumor cells to fall off, reduces the risk of implantation and metastasis, and compares the probability of wound bleeding, hematoma, and infection caused by injury small.
