Abstract
The utility model relates to a urethral puncture injection needle which comprises a sleeve guide pipe. The sleeve guide pipe is internally provided with 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.
Description
Technical field
This utility model relates to a kind of area of medical devices, particularly a kind of urethra puncture injection needle.
Background technology
When the symptoms such as prostatic hyperplasia, urethral stricture, hysterical urine retention occurring clinically, can cause dysuria, need to carry out direct injection to urethral wall.When needing clinically at present to carry out direct injection with entry needle in urethra, lack corresponding suitable instrument used for injection, head end is sharp-pointed, easily injure urethra when entering urethra, and entry needle is difficult to tell under ultrasound wave after entering urethra, tip position also is difficult to determine, can't inject accurately safety and shortage guarantee qualitatively at diseased region.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of reasonable in design, urethra puncture injection needle that accurately entry needle is taken to diseased region easy to use, safe is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme, a kind of urethra puncture injection needle, be characterized in: comprise the overcoat conduit, be provided with puncture injection needle in the overcoat conduit, the afterbody of described puncture injection needle is connected with the needle stand that coordinates with syringe, the leading section of described overcoat conduit is provided with the needle point outlet of puncture injection needle, is provided with the radiography line along the catheter body direction on the overcoat conduit, and the tail end of overcoat conduit is connected with hollow handle.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the length of described overcoat conduit and puncture injection needle equal in length.Because in urethra, tip position poorly determines, so just utilize catheter tip to locate, the overcoat conduit is with after puncture injection needle flushes, and catheter tip is the injection site namely.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described needle point outlet is located at the front end of overcoat conduit.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described puncture injection needle is the linear type puncture injection needle.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the front end closure of described overcoat conduit, and described needle point exports on the sidewall of the front portion that is located at the overcoat conduit, and the centrage of needle point outlet overlaps with the radiography line.
Technical problem to be solved in the utility model can also further realize by following technical scheme, is provided with the radiography granule in the front end of described overcoat conduit, is convenient to observe under ultrasound wave.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the front curvature of described puncture injection needle, angle of bend is 155 °-165 °, can make very easily puncture injection needle export out from the needle point on the anterior sidewall of overcoat conduit.
Technical problem to be solved in the utility model can also further realize by following technical scheme, the rear portion of hollow handle is provided with the gathering sill that the puncture injection needle needle stand moves, the hollow handle of gathering sill one side is provided with the bayonet socket that coordinates with the needle handle of needle stand, when not using, needle handle is placed on bayonet socket, during use, needle handle is pushed ahead along gathering sill.
Compared with prior art, puncture injection needle of the present utility model is in entering the process of urethra, entangle with the overcoat conduit, can prevent that puncture injection needle from scratching urethra, and puncture injection needle enters after urethra by tell the radiography line under ultrasound wave, can determine very accurately tip position, and diseased region is injected, it is easy to use, the taking entry needle to diseased region and inject of safety and precise.

The specific embodiment
With reference to accompanying drawing, a kind of urethra puncture injection needle, comprise overcoat conduit 3, be provided with puncture injection needle 5 in overcoat conduit 3, the afterbody of described puncture injection needle 5 is connected with the needle stand 7 that coordinates with syringe, and the leading section of described overcoat conduit 3 is provided with the needle point outlet 2 of puncture injection needle 5, is provided with radiography line 4 along the catheter body direction on overcoat conduit 3, can be with scale on radiography line 4, the tail end of overcoat conduit 3 is connected with hollow handle 6.The rear portion of hollow handle 6 is provided with the gathering sill 8 that puncture injection needle 5 needle stands 7 move, and the hollow handle 6 of gathering sill 8 one sides is provided with the bayonet socket 9 that coordinates with the needle handle of needle stand 7.
During use, first the needle stand 7 with puncture injection needle 5 is connected with the syringe that medicinal liquid is housed, and then penetrates in overcoat conduit 3, and the needle handle of puncture injection needle 5 is changed in bayonet socket 9.According to the radiography line 4 on overcoat conduit 3, under hyperacoustic guiding, overcoat conduit 3 and puncture injection needle 5 are inserted urethra, and overcoat conduit 3 is placed on puncture injection needle 5, avoids damaging urethra, puncture injection needle 5 has increased overcoat conduit 3 hardness simultaneously, be convenient to urethra and insert, after overcoat conduit 3 tops arrival diseased regions, promote puncture injection needle 5, puncture injection needle 5 is passed from the needle point outlet 2 of overcoat conduit 3, inject.
