Description

technical field [0001] The invention relates to the technical field of medical detection equipment, in particular to a semi-automatic and fully automatic percutaneous puncture biopsy needle. Background technique [0002] With the continuous development of the medical level, ultrasound-guided fine-needle aspiration cytology biopsy has been more and more used in daily medical treatment in recent years. This method is applied under ultrasonic monitoring, and the target cells of superficial organ tissues are obtained by lifting and inserting for pathological diagnosis, such as breast, thyroid, kidney, liver, lymph nodes, etc. Safe way. Compared with the previous histological biopsy, it has the advantages of less damage, less risk, and equally reliable results. This involves a very important tool - the puncture needle. [0003] The puncture needles currently used are hollow and extremely thin round tubular structures, with an outer diameter of 14-25G, corresponding to an outer...
