Abstract

The invention relates to a medical needle which acts on meridians and collaterals, in particular to a sword needle for meridians and collaterals. The sword needle for the meridians and collaterals is composed of a needle body and a needle handle. The sword needle for meridians and collaterals is characterized in that the needle handle includes a handle body, a containing hole is formed in the handle body, the containing hole includes a first hole section and a second hole section, a chuck and an ejector rod are sequentially arranged in the second hole section in a front-to-back mode, a central hole is formed in the center of the chuck, at least two long grooves along front-back direction are formed in the periphery of the rear end of the chuck in a evenly-distributed mode, the long grooves are all communicated with the central hole, and therefore the rear end of the chuck forms a multiple flap shape; a receding hole is formed in the center of the front end of the ejector rod, and the front end hole orifice of the receding hole abuts against the rear end of the chuck in a matching mode. When the ejector rod moves forward, the orifice of the receding hole presses the multiple-flap-shaped rear end of the chuck closed to enable the needle body to be clamped, and a positioning structure for positioning is arranged between the ejector rod and the handle body opposite to the ejector rod in the state; when the ejector movers backward, the orifice of the receding hole breaks away from the multiple-flap-shaped rear end of the chuck, and the needle body is loosened.
