Description
Technical Field
The utility model relates to an injector manufacturing industry, in particular to an injector for treating osteonecrosis.
Background
The injector consists of a syringe with a small hole at the front end and a matched piston core rod, and is used for injecting a small amount of liquid or extracting the liquid or the liquid from an inaccessible area by other methods, wherein the liquid or gas is sucked from the small hole at the front end of the syringe when the core rod is pulled out, and the liquid or gas is extruded when the core rod is pushed in.
At present, when the bone necrosis is treated, the injection needle of the injector needs to be punctured into the bone of a patient for applying the medicine, after the medicine is applied, the injection needle is very easy to be clamped, so that the pintle is separated from the needle nozzle and is not easy to be pulled out, and the injector with firmer pintle and needle nozzle connection is needed.
