Abstract
The utility model discloses a novel puncture needle for the nephrology department and relates to the technical field of medical instruments. The novel puncture needle for the nephrology department comprises a needle body and a needle tip. A transparent blind pipe is arranged outside the needle body. An annular air cavity is arranged close to the needle tip and on the needle body. A fixing sleeve is arranged outside the transparent blind pipe and is provided with a fixing screw. A needle handle is arranged at the tail end of the needle body and is provided with a groove. The outer surface of the needle handle is provided with rubber threads. The novel puncture needle for the nephrology department has the advantages of being simple in structure, convenient to use, capable of effectively controlling puncture depth and clearly separating the needle body from a kidney and surrounding tissues through ultrasound, and accurate in puncture location, and reducing work difficulty of medical workers.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of New Kidney internal medicine puncture needle.
Background technology
The renal puncture biopsy is a kind of important method of diagnosis of kidney disease, when using clinically at present the capable renal needle biopsy of kidney puncture needle, needs two people operation, aspirates negative pressure by the assistant.During puncture puncture needle is thrust, depth of needle will be used ruler measurement repeatedly, makes troubles impact puncture quality to operation.After having measured paracentesis depth during puncture, be fixed on the puncture needle with finger, with definite puncture depth of needle, but it is mobile to be prone to finger in the operating process, and affects the accuracy of paracentesis depth.In addition, common puncture needle is very unintelligible in ultrasonic lower projection, is difficult to kidney and surrounding tissue distinguishes, and the site of puncture is determined inaccurate, and this has just increased work difficulty to the medical personnel.
The utility model content
This utility model is for the prior art above shortcomings, a kind of New Kidney internal medicine puncture needle is provided, this New Kidney internal medicine with puncture needle by the design of transparent blind pipe so that can be clear under ultrasonic needle body and kidney and surrounding tissue be distinguished, the design by the annular air chamber is so that the Urology Department doctor further judges the inserting needle situation simultaneously.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of New Kidney internal medicine puncture needle, comprise needle body, needle point, described needle body is provided with transparent blind pipe outward, be provided with the annular air chamber near described needle point place on the described needle body, described transparent blind pipe outside is provided with fixed cover, and described fixed cover is provided with hold-down screw, and described needle body end is provided with needle handle, described needle handle is provided with groove, and described needle handle outer surface is provided with the rubber screw thread.
It is conical that described needle point is.
This utility model beneficial effect: simple in structure, easy to use, can effectively control paracentesis depth, can be clear under ultrasonic needle body and kidney and surrounding tissue be distinguished, the puncture accurate positioning has alleviated medical worker's work difficulty.
Description of drawings
Fig. 1 is New Kidney internal medicine puncture needle structure sketch map described in the utility model.
Among the figure:
The 1-needle body; The 2-needle point; The transparent blind pipe of 3-; 4-annular air chamber; 5-rubber screw thread; The 6-fixed cover; The 7-hold-down screw; The 8-needle handle; The 9-groove.
The specific embodiment
The below is described in further detail this utility model with embodiment with reference to the accompanying drawings:
As shown in Figure 1, a kind of New Kidney internal medicine puncture needle, comprise needle body 1, needle point 2, it is conical that described needle point 2 is, be provided with transparent blind pipe 3 outside the described needle body 1, under ultrasonic, can clear needle body 1 and kidney and surrounding tissue be distinguished, be convenient to it is checked, be provided with annular air chamber 4 near described needle point 2 places on the described needle body 1, because ultrasonic have strong reflexive to air, make the boundary of kidney and surrounding tissue clear in the ultrasonic machine fluorescent screen, can effectively help the Urology Department doctor to judge the inserting needle situation, described needle body 1 middle part is provided with fixed cover 6, and described fixed cover 6 is provided with hold-down screw 7, fixed cover 6 can slide along transparent blind pipe 3, and then needle body 1 is fixing, described needle body 1 end is provided with needle handle 8, and described needle handle 8 is provided with groove 9, described needle handle 8 outer surfaces are provided with rubber screw thread 5, and the medical worker will hold in the above can not carry out maloperation to the patient because hands is sliding.
During use, the medical worker is with holding on the groove 9 of needle handle 8, syringe needle is lunged in the patient body, and it is clear that annular air chamber 4 can make the boundary of kidney and surrounding tissue under ultrasonic effect, when the degree of depth is suitable, fixed cover 6 slides along transparent blind pipe 3, tighten hold-down screw 7, and then needle body 1 is fixed, then transparent blind pipe 3, under ultrasonic, can clear needle body 1 and kidney and surrounding tissue be distinguished, check.
Claims (2)
