Disposable varicosity syringe needle

Abstract

The invention relates to the technical field of syringe needles, and specifically discloses a disposable varicosity syringe needle. The disposable varicosity syringe needle comprises a syringe needle body, wherein the syringe needle body comprises a handle, a Luer taper and a puncture needle; the left end of the handle is fixedly connected with a first fixing disk; the right end of the handle is fixedly connected with a second fixing disk; and the surface of a rod body of the puncture needle is in fixed sleeving with a movable loop bar. The disposable varicosity syringe needle can move the movable loop bar effectively by slowly screwing a regulation wheel, so that the puncture needle slowly reaches a predetermined injection point through a biopsy channel, in addition, when the regulation wheel is close to a first spacing card and a second spacing card, the rotation number of degrees of the regulation wheel can be restricted, i.e., a medical person is forced to only screw the regulation wheel in a gap so as to lower the pushing-in speed of the puncture needle, so that a phenomenon that the puncture needle is close to an injection point too fast can be avoided, and finally, the puncture needle is more safely close to the injection point.

Description

technical field [0001] The invention relates to the technical field of injection needles, in particular to a disposable varicose vein injection needle. Background technique [0002] Varicose veins are one of the most common diseases in extremity vascular diseases. Varicose veins mostly occur in the lower extremities. The main reason for the formation of varicose veins is that the congenital vascular wall membrane is relatively weak or the same posture is rarely changed for a long time, blood accumulates in the lower limbs, and the venous valve is damaged over time, resulting in excessive venous pressure, which makes the blood vessels protrude from the skin surface symptom. In many operations, intracavitary coagulation of varicose veins with sclerosing agents is a more convenient operation. It is an intracavitary injection of sclerosing agents to varicose veins to occlude the varicose great saphenous vein, organize the tissue, absorb the tissue, and then the varicose vein ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a disposable varicose vein injection needle. The design can accurately send the puncture needle to the injection point, and can ensure the stability of the puncture needle during the sending process, avoiding puncture The advantage of the return movement of the needle solves the problems in the prior art that the use and operation of the puncture needle are troublesome and have certain safety hazards
