Novel ultrasonic guided puncture washing needle

Abstract

The invention provides a novel ultrasonic guided puncture washing needle, and belongs to the technical field of medical instruments. The novel ultrasonic guided puncture washing needle comprises an inner core, a needle tube and an electric knife, wherein the inner core, the electric knife and the needle tube are detachably arranged. The washing needle has two use states, wherein one state is thatthe inner core is inserted into an inner cavity of the needle tube, and the other state is that one end, which is provided with a cutting knife, of the electric knife is inserted into the inner cavityof the needle tube,, wherein the cutting knife is used for crushing viscous hydrops or fiber tissues. The needle tube is in a double-cavity structure and comprises an inner cavity and an outer cavity; the outer cavity is wrapped outside the inner cavity; the outer cavity is used for feeding water and flushing liquid; and the inner cavity is used for sucking diluted hydrops. The novel ultrasonic guided puncture washing needle not only can fully smash the viscous hydrops or the fibrous tissues, but also can dilute the viscous hydrops while sucking the hydrops, so that a better treatment effectis achieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a novel ultrasound-guided puncture washing needle. Background technique [0002] For infected pleural and peritoneal effusions, as well as cystic lesions of some solid organs (such as liver abscess, cystic echinococcosis of the liver, etc.), ultrasound-guided puncture and drainage is a common treatment method, and the curative effect is definite. The traditional treatment method is to insert a puncture needle into the effusion or cyst cavity to directly aspirate, or to insert a drainage tube along the puncture needle track for continuous drainage, but these methods have certain problems. After mechanicalization, it may become very viscous, or there are many fibrous separations, which will block the puncture needle and cause suction difficulties, which will eventually lead to treatment failure. Better dilute the cystic fluid to achieve adequate drainage. For this reason,...
