Abstract

Disclosed is a biopsy needle with hemostasis function, which includes: a sampling needle; a cutting needle assembly including a cutting needle and an inner insulating layer covering a periphery of the cutting needle, where the cutting needle is fitted over a periphery of the sampling needle, with the distal end of the cutting needle exposed beyond the inner insulating layer to form a first electrode with the distal end of the sampling needle; a cannula assembly including a cannula and an outer insulating layer, an outer insulating layer, and a cannula plug, where the outer insulating layer covers a periphery of a cannula, with a distal end of the cannula exposed beyond the outer insulating layer to form a second electrode, the cannula assembly is configured to be detachably connected to a handle of the biopsy needle via the cannula plug, allowing the cannula to be coaxially fitted over the periphery of the cutting needle; the proximal ends of the sampling needle and the cannula plug are respectively electrically connected to a power supply device to enable the insertion of the sampling needle and the cutting needle assembly into the cannula after sample tissue extraction, and the application of electrical energy to perform hemostasis operation on the needle tract using the first electrode and the second electrode.
