Problems solved by technology

[0002] Biopsy needle is a kind of biopsy needle used for sampling and absorbing cells of pyramidal tumors and unknown tumors in various organs such as kidney, liver, lung, breast, thyroid, prostate, pancreas, testis, uterus, ovary, and body surface. For medical devices, some of the existing one-time biopsy needles with multiple integrated structures need to be discarded after use, the purchase cost is high, and the operation is not convenient enough to take out samples. Therefore, we propose a one-time sex cytology biopsy needle
