Description

Syringe for treating osteonecrosis

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.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides a syringe for treating osteonecrosis. The utility model provides a technical scheme that its technical problem adopted is: the structure of the utility model comprises a needle cylinder, an internal thread tube, a thread, a needle nozzle, a pintle card, and is characterized in that the injector is at least provided with the internal thread tube with the thread outside the needle nozzle at the front end of the needle cylinder, and the pintle of the pintle card is arranged at the tail part of the injector.

Preferably, the needle cylinder top is equipped with the needle mouth, and the outside of needle mouth sets up the internal thread pipe, and the bottom of internal thread pipe is connected with the needle cylinder, the inside screw thread that is equipped with of internal thread pipe, the top of internal thread pipe is less than the height of needle mouth, needle mouth department connects the pintle, and the afterbody of pintle is equipped with the pintle card, and the both sides of pintle card are equipped with crescent bulge respectively, the pintle card matches with the screw thread of internal thread pipe.

Preferably, 2-3 holes are arranged on the side surface of the front end of the injection needle connected with the pintle.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses novel structure, it is simple and convenient to use, the utility model discloses a pintle card of pintle and the screw thread swivelling joint back of internal thread pipe can make pintle and needle mouth be difficult for breaking away from, can bear great pulling force, excellent in use effect.
