SPLIT-TYPE ABLATION NEEDLE AND CRYOABLATION PUNCTURE SYSTEM

Abstract

A split-type ablation needle connected to a cryoablation device comprising a needle arranged at a distal end of the split-type ablation needle; a tube body connected to the needle, wherein two second channels used for delivering a medium to the needle and delivering the medium returned from the needle respectively, and an insulation structure circumferentially wrapping the exterior of the two second channels, are provided inside the tube body; and a second-type joint, comprising a second connector and a second cavity. The split-type ablation needle is enable to be disassembled from the cryoablation device for puncture only, thereby reducing the impact of the tail weight of the split-type ablation needle on the puncture process.
