Abstract
The utility model discloses a kidney puncture needle, which relates to the technical field of medical appliances. The kidney puncture needle is made of stainless steel, and an annular switched layer containing air is disposed at a needle tip portion of the kidney puncture needle. During usage, the kidney puncture needle is guided by ultrasound, and as the ultrasound has strong reflectivity to air, a boundary of the annular switched layer containing air of the needle tip portion of the kidney puncture needle, kidneys and surrounded tissues thereof is clear on a screen of an ultrasonic machine, thereby being capable of assisting a doctor in a nephrology department to judge needle inlet conditions. The annular switched layer is convenient in processing and manufacturing, is formed by only cutting a section of stainless steel circular pipe with diameter slightly larger or smaller than that of the kidney puncture needle to be welded at the needle tip portion of the kidney puncture needle, and is relatively low in cost.
Description
Technical field
This utility model relates to technical field of medical instruments, relates in particular to a kind of kidney puncture needle.
Background technology
The renal puncture biopsy is a kind of method of judging that the nephropathy type is commonly used, and the Urology Department doctor can carry out blind wearing by rule of thumb generally speaking.Universal day by day along with ultrasonic instrument, it is then more accurate to carry out renal puncture under ultrasonic guidance, because common puncture needle ultrasonic down very not clear with kidney and surrounding tissue boundary, especially for the Urology Department doctor who does not often see ultrasonic image, needs and please ultrasonic doctor hold a consultation.There is the people that existing puncture needle is improved for this reason, makes it, judge the inserting needle situation to help the Urology Department doctor ultrasonic following clear with kidney and surrounding tissue boundary.Disclosed by utility model patent Liu Xinrong, Song Tao design, that the patent No. is 200620147684.9, name is called a kind of kidney puncture needle as State Intellectual Property Office on October 31st, 2007, this apparatus structure comprises a kidney puncture needle, make by rustless steel, the needle point position of this kidney puncture needle is welded with the ellipse stainless steel ball of a hollow, and the hollow part of ellipse stainless steel ball contains air.Owing to ultrasonic air is had intensive reflexive, it is clear with kidney and surrounding tissue boundary on the ultrasonic machine fluorescent screen to make renal puncture needle tip position contain the ellipse stainless steel ball of air, can help the Urology Department doctor to judge the inserting needle situation.Its shortcoming is that ellipse stainless steel ball itself is difficult for making, and also inconvenient with the welding of kidney puncture needle needle point position, as not prison welding it is fallen in the kidney, brings unnecessary trouble.
Summary of the invention
The purpose of this utility model is to provide a kind of processing and fabricating convenience, low, the safe and reliable kidney puncture needle of cost.
The technical scheme that this utility model is adopted for achieving the above object is:
A kind of kidney puncture needle is made by rustless steel, it is characterized in that: described kidney puncture needle needle point position is provided with the annular gap that contains air.
During use, this utility model kidney puncture needle carries out under ultrasonic guidance, because ultrasonic have intensive reflexive to air, the annular gap that can make this utility model renal puncture needle tip position contain air is clear with kidney and surrounding tissue boundary on the ultrasonic machine fluorescent screen, can help the Urology Department doctor to judge the inserting needle situation.And this annular gap processing and fabricating is convenient, and the needle point position that only needs one section diameter stainless pipe big or slightly littler slightly than the diameter of kidney puncture needle of intercepting to be welded in kidney puncture needle gets final product, and cost is lower.
Description of drawings
Fig. 1 is the sketch map of this utility model kidney puncture needle embodiment one.
Fig. 2 is the sketch map of this utility model kidney puncture needle embodiment two.
Among the figure: 1-kidney puncture needle, 2-annular gap.
The specific embodiment
Fig. 1 is the sketch map of this utility model kidney puncture needle embodiment 1, the 1st, this utility model kidney puncture needle, made by rustless steel, kidney puncture needle 1 needle point position is provided with the annular gap 2 that contains air, and annular gap 2 is positioned at kidney puncture needle 1 needle point position and gets the outside.During use, can under ultrasonic guidance, carry out during kidney puncture needle 1 puncture, because ultrasonic that the annular gap 2 that contains air is had intensive reflexive is can be on the screen of ultrasonic machine clear with kidney and surrounding tissue boundary, can help the Urology Department doctor to judge the inserting needle situation.
Fig. 2 is the sketch map of this utility model kidney puncture needle embodiment 2, the 1st, this utility model kidney puncture needle, made by rustless steel, kidney puncture needle 1 needle point position is provided with the annular gap 2 that contains air, and annular gap 2 is positioned at kidney puncture needle 1 needle point position and gets inboard.
