Abstract

The invention discloses an electric resection biopsy needle, an electric resection biopsy needle suite and a vacuum-assisted breast biopsy system. The electric resection biopsy needle comprises a puncture assembly, wherein the puncture assembly comprises a puncture tube, the puncture tube is provided with a front end and a rear end, and the tube wall of the puncture tube is provided with a sampling groove; a cutting assembly which comprises a cutting piece, wherein the cutting piece can reciprocate back and forth in the axial direction of the puncture tube, the cutting assembly is provided with a first electrode, the puncture assembly is provided with a second electrode, and a first interface and a second interface which are electrically connected with the first electrode and the second electrode respectively, wherein any one of the first interface and the second interface is used for being directly or indirectly connected with a high-frequency output end of a host, and the other interface is used for being directly or indirectly connected with a high-frequency input end of the host. According to the electric resection biopsy needle with the structure, radio waves between the cutting edge and the puncture tube are used for cutting tissue, and the electric resection biopsy needle has the advantages of being high in safety, convenient to operate, simple in structure and low in cost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an electrocution biopsy needle, an electrocution biopsy needle set and a vacuum-assisted breast biopsy system. Background technique [0002] The Vacuum Assisted Breast Biopsy System is a medical device used for the minimally invasive treatment or biopsy of breast masses (tumors). The vacuum-assisted breast biopsy system is mainly composed of a host, a biopsy device, and a vacuum negative pressure system. The system mainly punctures the biopsy needle of the biopsy surgical device to the operation point under the guidance of imaging equipment (such as B-ultrasound), and then uses electrical control to make the biopsy needle perform partial or complete rotary resection of the lesion tissue through mechanical movement. And the rotary cut tissue specimens are finally transported to the outside through negative pressure, and then used for film production, pathological detectio...
