Abstract

The invention discloses a percutaneous puncture biopsy needle. The needle comprises a needle tubing, a needle core and a handle operation end, the handle operation end comprises an outer shell, an inner sleeve, an anti-error button, a rear percussion button, a left button and a right button, and the outer shell comprises an upper cover and a lower cover; the inner sleeve is arranged in the outer shell and comprises an inner sleeve upper cover and an inner sleeve lower cover, and an inner sleeve structure surface and a movable assembly are further arranged in the inner sleeve; the movable assembly comprises a needle core base, a buffer cushion, a needle tubing base, a front spring and a rear spring, the needle core base is connected with the tail of the needle core, and the buffer cushion is connected with a side hole of the needle core base; the rear spring sleeves the tail of the needle core base, the needle tubing base is connected with the tail of the needle tubing, and the front spring sleeves the tail of the needle tubing base. According to the percutaneous puncture biopsy needle, the inner sleeve structure surface divides an inner cavity of the inner sleeve into a front cavity and a rear cavity, the front cavity can contain the needle tubing base and the front spring, and the rear cavity can contain the needle core base and the rear spring. The percutaneous puncture biopsy needle is reasonable in structure and high in safety, and a user can operate the needle by single hand.

Description

technical field [0001] The invention relates to the technical field of medical detection equipment, in particular to a percutaneous 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 diameter of 2.1mm-0.4mm, which can be equip...
