Urethral puncture injection needle

Abstract

The invention relates to a urethral puncture injection needle which comprises a sleeve guide pipe. The sleeve guide pipe is internally provided width a puncture injection needle; the tail part of the puncture injection needle is connected with a needle base which is matched with an injection syringe; the front end part of the sleeve guide pipe is provided with a puncture injection needle point outlet; a contrast line is arranged on the sleeve guide pipe along the direction of the body of the sleeve guide pipe; and the tail end of the sleeve guide pipe is connected with a hollow handle. Before the urethral puncture injection needle enters the urethra, the urethral puncture injection needle is sleeved by the sleeve guide pipe so as to avoid scratching the urethra. After the urethral puncture injection needle enters the urethra, the contrast line is distinguished under the ultrasonic wave, so that the position of the puncture injection needle point can be determined accurately, and the liquid medicine can be injected into the diseased part. The urethral puncture injection needle is convenient to use and can be used for injecting a liquid medicine into the diseased part safely and accurately.
