Abstract

The invention discloses a biopsy needle and system. The biopsy needle comprises an inner tube, an outer telescopic piece, a tool bit and an electrode; the tool bit is arranged at the far end of the inner tube; the outer telescopic piece is configured to be arranged outside the inner tube in a sleeving mode and can be close to or away from the tool bit in the axial direction of the inner tube; one end of the electrode is connected with the tool bit, the other end of the electrode is connected with the far end of the outer telescopic piece, and the far end of the outer telescopic piece is the end, close to the tool bit, of the outer telescopic piece; in the process that the outer telescopic piece gets close to the tool bit in the axial direction of the inner tube, the electrode can be extruded to be bent outwards, and outward bending means that the electrode is bent away from the inner tube; and after the outer telescopic piece approaches the tool bit to a target position in the axial direction of the inner tube, the electrode is configured to rotate around the axial direction of the inner tube. According to the invention, sampling is carried out in a high-frequency electrotome rotary cutting mode, so that the problems of bleeding, complex structure, high cost and easy failure in the sampling of the existing physical cutting mode are solved.

Description

technical field [0001] The invention relates to the technical field of biopsy, in particular to a biopsy needle and a system. Background technique [0002] In today's society, with the improvement of people's living standards, the advancement of the times and technology, and the improvement of medical standards, people's awareness of their own health is also increasing. In recent years, the incidence of cancer has been increasing. Prior to this, lung cancer has always been the most common cancer in the world. According to the latest data in 2020, the number of new breast cancers has reached 2.26 million, and the number of lung cancers has increased to 2.2 million. Replaced lung cancer as the world's leading cancer. [0003] Breast cancer is not an incurable cancer, and the cure rate is quite high when it is detected in the early stage, up to 70% or even higher. Therefore, regular breast examination is the best preventive measure to reduce the incidence of breast cancer. ...
