Description
Technical field
The utility model relates to a kind of ultrasonic development enhance puncture needle, for Issues of Human Assisted Reproductive Technologies (ART) ultrasound at
As guidance oocyte retrieval, belong to medical instruments field.
Background technique
In the medical field, it is guided by ultrasonography, puncture needle is used to puncture to acquire body target site
Liquid, tissue, cell or importing medical fluid etc..In art, doctor is placed on ultrasonic probe to site of puncture or to site of puncture body surface, from
The raking of probe.On the display screen of imaging system, it can be seen that institutional framework, needle and needle point are worn to accurately hold
Pricker reaches target position.In the actual operation process, since puncture needle outside wall surface is smooth, it is anti-that mirror surface is generated to incident acoustic wave
It penetrates, and puncture needle and the angle of ultrasonic beam are smaller (angle of needle more tilts), can be got over by the received sound wave of ultrasonic probe
Few, puncture needle is less susceptible to develop, and can't see needle or syringe needle on the display screen of ultrasonic image-forming system, and it is fixed to greatly reduce ultrasound
The accuracy of position puncture needle.It is related to Issues of Human Assisted Reproductive Technologies (Assisted Reproductive Technology, ART) neck
Domain also generallys use ultrasonic imaging guidance and is punctured specifically in Oocyte Pickup by Vagina Puncturing.It is well known, in such hand
In art, above-mentioned puncture needle or the unsharp problem of syringe needle development are equally existed.
For the unsharp problem of puncture needle ultrasonic development, existing patent proposes solution:
Chinese patent 200580051150.4 discloses a kind of puncturing needle for ultrasound wave, is formed in the front end of needle body
There is sharp point, in the specified position of needle body, by the pit of triangular pyramid at least formed with a corner cube mirror.Even if
When the angle that the axis of the exposure pathways of ultrasonic wave and puncture needle is formed is smaller, the puncture needle that can also clearly be imaged.
Chinese patent 200610066108.6 provides a kind of puncture needle, by having the outer cylinder of the tubulose of sword head in front end
Needle and insertion are combined intracavitary interior needle in above-mentioned outer cylinder needle and are constituted；To from the sword head of above-mentioned outer cylinder needle to the region of cardinal extremity
Recessed processing is implemented in periphery, and implements coarse processing to the periphery since the front end of above-mentioned interior needle to the region of cardinal extremity.In this way,
In ultrasonic image-guided puncture, it can be seen that the distincter ultrasonic development until sword head end of puncture needle.
However, in a kind of technical solution of puncturing needle for ultrasound wave disclosed in the patent 200580051150.4, although its
The ultrasonic imaging of front end is clear, and the part ultrasonic development that remaining is not processed is unsatisfactory.In addition, for without resinous coat
Puncture needle will increase the penetration Resistance of needle using the pit of electric machining or punching press production triangular pyramid.Patent
In a kind of puncture needle disclosed in 200610066108.6, if remain cannot will for the coarse processing supplement outer cylinder needle of non-used interior needle
Ultrasonic reflections to diagnostic ultrasound equipment test section position, due to remained in the recessed processing of the periphery of outer cylinder needle plus
The smooth outer peripheral surface of work, puncture needle can be decreased obviously until the ultrasonic development effect of its sword head end.
For the puncture needle for being used to take ovum in oocyte retrieval, in the prior art, generally by the nearly needle point of puncture needle
Region carries out specially treated, such as processing groove or protrusion, and the region of the nearly needle point of puncture needle is made to have more ultrasonic waves to be popped one's head in
It receives, to enhance the ultrasonic development in the region.
United States Patent (USP) US7470249 discloses a kind of suction for taking out egg mother cell and rinses needle assemblies, in the component
Flushing needle is characterized in that: improving the ultrasonic echo of flushing needle such as impression, annular knurl by specially treated to the front end of flushing needle
Feature.
Chinese patent 201720152801.9 discloses a kind of image feedback and takes ovum needle, and the front end of stainless steel needle tubing is equipped with abdomen
Sword needle point or back abdomen twolip needle point, the stainless pin pipe surface on rear side of needle point are equipped with image and feed back area；Image feeds back area
Surface is in point shape, frosted shape or shape of threads.
Chinese patent 201220497802.4 discloses a kind of puncture of oocyte collector with ultrasonic wave positioning line
Needle comprising needle tubing is formed with needle point on the front end face of needle tubing, and ultrasonic wave identification line is formed on the front end outer wall of needle tubing, is surpassed
Sound wave identification line is made of multiple annular recess for being arranged successively and being parallel to each other along needle tubing central axes.It is specific: adjacent ring
There is certain interval between shape groove；The width of annular recess is 0.1mm~1mm；Ultrasonic wave identifies that the axial length of line is 5mm
~30mm.
What Chinese patent 201810132418.6 disclosed a kind of suitable one-handed performance takes ovum system, puncture needle in the system
Be characterized in that: the front end of the puncture needle is equipped with ultrasonic wave and identifies line；Ultrasonic wave identifies that the axial length of line is 4mm~30mm.
In the specific embodiment of the patent, ultrasonic wave identifies that line can identify that line, loop-shaped ultrasound identify line by more for loop-shaped ultrasound
Dotted groove is arranged to constitute.
It can be seen that the technology of above-mentioned patent disclosure carries out specially treated by the front end to needle mostly, such as before needle
Grooves or the protrusions such as dotted, frosted shape, shape of threads, ring-type are added in end, enhance the ultrasonic imaging of syringe needle, are promoted to a certain extent
The accuracy of puncture needle localization by ultrasonic.Although can be obtained in a kind of puncture needle disclosed in patent 200610066108.6 until
Distincter ultrasonic development until the sword head end of puncture needle, if removing coarse processing (such as puncture needle only list of interior needle
Pipe construction), merely with the recessed processing of the periphery of outer cylinder needle, will lead to until the ultrasonic development of puncture needle sword head end is not very clear
Clear, the validity of the method is lowered.
In addition, during ova harvest, especially puncture carry out when, operator generally requires sight from display screen
It moves on on puncture needle, confirms depth of needle by observing puncture needle on hand, doctor, which operates, to be inconvenient, and is also affected
The accuracy of surgical procedure.Well known, the effective length of the puncture needle of ova harvest is longer, about 30cm~35cm, even if
The puncture needle head ultrasonic imaging of prior art is clear and legible, and due to puncture needle, remaining position for not carrying out specially treated surpasses
Sound development is difficult, and doctor can not directly observe depth of needle in real time on a display screen, also reduces the accuracy of surgical procedure.
Utility model content
The purpose of the utility model is to overcome the defects of the prior art, provide a kind of ultrasonic development enhancing puncture needle, make to wear
The ultrasonic imaging of pricker is presented light and dark scale, real directly on the display screen of ultrasonic image-forming system in easily operated person's art
When observe depth of needle, keep surgical procedure more accurate.
Realizing the technical solution of above-mentioned purpose is: a kind of ultrasonic development enhances puncture needle, including needle tubing and coupled
Needle point is provided with ultrasonic development enhancing band group in the outside wall surface of the needle tubing；
The ultrasonic development enhancing band group enhances band comprising several ultrasonic developments, several described ultrasonic developments enhance band
