Cauterization needle device, high frequency cauterization treatment system and chemical cauterization treatment system

摘要

It is an object of the present invention to provide an actionable needle device that can be used for the treatment of jugular vein catheterization for primary adenosterosis. The action needle device of the present invention is an action needle device for performing cauterization treatment of adrenal tumors by injecting an injection needle into the adrenal vein, and includes a sharp tubular tip 11 and a tubular proximal portion 12 It is made of a metal injection needle 10 and a gripping portion 20 mounted on the proximal end side of the injection needle 10, and the proximal end portion 12 of the injection needle 10 is in the tip region 12A. While the spiral slit 14 is formed to provide flexibility, the outer surface of the proximal end 12 is covered with a resin 16, and the distal end 11 of the injection needle 10 is closed. At the same time, a plurality of pores 15 are formed on the outer surface of the distal end portion 11 including the obstruction portion 13, and the gripping portion 20 is supplied with liquid to the lumen of the injection needle 10. A liquid injection port 25 is provided for the purpose.
