成果简介	NOVELTY - The needle has a stylet that is located in a cannula (1) and made with a sharpening with possibility of reciprocating movement relative to the cannula. Distal end (6) of the stylet protrudes beyond distal end (3) of the cannula, and a syringe connector (4) is located at a proximal end of the cannula. Outer surfaces of the cannula and the stylet have electrically insulating coatings that do not reach the distal ends, and an electrical connector (8) designed for connection to measuring device using a cable (9) is provided at proximal end of the stylet. A contact surface of electrical connector for connection with cannula is electrically insulated from the stylet by electrically insulating coating. USE - Biopsy needle used for targeted aspiration and trepanation biopsy of soft tissue and internal organ using beam guidance and bioimpedance control. ADVANTAGE - The needle can increase the accuracy of targeting a biopsy needle to a tumor site due to the possibility of assessing changes in tissue electrical conductivity using multifrequency impedancemetry along the entire trajectory of the needle and when the tip of the needle hits the tumor tissue. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the biopsy needle in assembled state. 1Cannula 3Distal end of the cannula 4Syringe connector 6Distal end of the stylet 8Electrical connector designed for connection to measuring device 9Cable
