Abstract
The utility model discloses a kidney puncture needle, which comprises a needle body and a needle handle fixedly arranged together with the needle body. Air cavities distributed along the length direction of the needle body are arranged inside the needle body; and the air cavities annularly surround an inner cavity of the needle body. As the air cavities are arranged into an annular shape surrounding the inner cavity of the needle body, the needle body can be presented more completely both in length and width under ultrasonic wave so as to bring more convenience for doctors to more accurately control accurate positions for the kidney puncture needle, and to achieve better effect. The kidney puncture needle has reasonable structure and clear imaging under ultrasonic wave, is suitable for being used in various kidney puncturing occasions, particularly suitable for being used in occasions incapable of accurately controlling puncture positions, and helps to increase puncture efficiency.
Description
Technical field
This utility model relates to a kind of kidney puncture needle.
Background technology
Kidney puncture needle be the doctor be used for carrying out the renal puncture biopsy must use instrument, by the renal puncture biopsy, the doctor can fully understand the kidney state, thereby kidney disease is made diagnosis accurately.Traditional kidney puncture needle comprises needle body and the needle handle that is solid-located with needle body at present, the doctor is when carrying out the renal puncture biopsy, control needle handle, by rule of thumb needle body is thrust the human kidney position then, therefore its puncture position order of accuarcy is relatively poor, for the empirical doctor that do not puncture, the puncture effect is poorer.Extensive use along with excusing from death ripple instrument, utilize ultrasound wave must get more and more to the kidney puncture needle navigation application that punctures, but, it is not clearly that the puncture needle of traditional structure is demarcated with kidney and surrounding tissue thereof under ultrasound wave, cause having children outside the state plan image blurring, be unfavorable for that the doctor punctures accurately and rapidly.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of clearly kidney puncture needle of imaging under a kind of rational in infrastructure, ultrasound wave at above-mentioned deficiency.
For solving the problems of the technologies described above, this kidney puncture needle comprises needle body and the needle handle that is solid-located with needle body, and its construction features is: be provided with the air chamber that distributes along the needle body length direction in the needle body.
The kidney puncture needle of this structure is to realize that by the air chamber catoptric arrangement imaging clearly under the ultrasound wave.The air chamber catoptric arrangement comprises and is arranged on the intravital air chamber of pin that air chamber distributes along the needle body length direction, is loaded with air in the air chamber.Because air has intensive reflexive to ultrasound wave, therefore, under ultrasound wave, the imaging of air chamber is just obviously distinguished with kidney and surrounding tissue thereof and is come, and will present a strip tape along the air chamber that the needle body length direction distributes, like this, the doctor is when carrying out renal puncture, just can accurately judge the position of kidney puncture needle, thereby accurately puncture according to the position that air chamber presents strip tape.
As improvement, air chamber is the ring-type around needle lumen.
Air chamber is arranged to ring-type around needle lumen, can makes needle body under ultrasound wave, no matter still embodying more comprehensively on the width on the length, will more help the accurate position that the doctor accurately grasps kidney puncture needle, the puncture better effects if.
In sum, adopt the kidney puncture needle of this structure, under rational in infrastructure, the ultrasound wave imaging clear, be adapted at various renal puncture occasions and use, be particluarly suitable for accurately holding under the occasion of puncture position and use, help to improve puncture efficient.
Description of drawings
In conjunction with the accompanying drawings this utility model is described in further details:
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1 is needle body, and 2 is needle handle, and 3 is air chamber.
The specific embodiment
As shown in Figure 1, structural representation for this utility model, this kidney puncture needle comprises needle body 1 and the needle handle 2 that is solid-located with needle body 1, be provided with the air chamber 3 that distributes along needle body 1 length direction in the needle body 1, be loaded with air in the air chamber 3, air has intensive reflexive to ultrasound wave, therefore, air chamber 3 will have tangible difference with kidney and surrounding tissue thereof under ultrasound wave, like this, the doctor just can grasp the accurate position of needle body 1 according to the guide of air chamber 3 when carrying out renal puncture, thereby realizes accurately puncture.In order further to improve the assurance degree of doctor to the accurate position of needle body, air chamber 3 is designed to ring-type around needle body 1 inner chamber, like this, the imaging area of air chamber 3 will be more near the actual size of needle body 1, can improve doctor's renal puncture effect greatly.
Claims (2)
1. kidney puncture needle, comprise needle body (1) and with the needle handle (2) that needle body (1) is solid-located, it is characterized in that: be provided with the air chamber (3) that distributes along needle body (1) length direction in the needle body (1).
2. kidney puncture needle as claimed in claim 1 is characterized in that: air chamber (3) is around the ring-type of needle body (1) inner chamber.
