Description
Technical field
The present invention relates to medical instruments field, be specifically related to a kind of therapeutic medical puncture needle.
Background technology
In the past, in order to endoceliac affected part being carried out check diagnosis, having carried out suction and having extracted body cavity inner tissue, the hands of body fluid
Method；By utilizing ultrasonic endoscope to observing in body cavity while using puncture needle to run through Stomach duodenum
Digestive canal walls etc. also carry out this maneuver, by this hands to the target site puncture puncture needle of the deep internal organs such as pancreas, liver, kidney
It is referred to as endoscopic ultrasound-guided fine-needle aspiration biopsy, in recent years, by arranging ultrasonic reflections face on the needle tubing of puncture needle
It is accurately positioned, and then comes aspirate tissue, body fluid such that it is able to reach the raising of therapeutic effect and alleviating of side effect；But,
At present the formation of reflecting surface is mostly to offer circular groove or spiral groove on needle tubing, again or the master of needle tubing
Surface is formed has effigurate groove, but the ultrasonography that any method all can cause puncture needle is unclear
Clear, it is difficult to hold the tram of puncture needle, therefore, study and a kind of can accurately determine that the position of puncture needle has important meaning
Justice.
Summary of the invention
It is an object of the invention to provide a kind of puncture needle, it can make the ultrasonography of puncture needle clearly, accurate assurance
The position of puncture needle.
The technical scheme is that a kind of puncture needle, including cannula body portion and syringe tip, described cannula body
Portion comprises a cavity, and cavity connects with syringe tip, and described syringe tip is the inclined plane with a tip, described cannula body
Being formed with endless groove in portion, the formation the first side wall of endless groove, the bottom of the second sidewall are intersected, described the first side wall and the second side
Wall is respectively formed on the wall of peaking wave, and relative to the crest of axis the first side wall of described endless groove and the second side
The crest of wall is oppositely arranged, and the trough of the first side wall and the trough of the second sidewall are oppositely arranged.
Angle a that the bottom of described the first side wall and the second sidewall is formed is at least 30 degree.
Peaking wave wall on described the first side wall and the second sidewall is set to zigzag fashion.
Zigzag fashion wall on described the first side wall and the second sidewall is set to the axis pair along described endless groove
Claim distribution.
Peaking wave wall on described the first side wall and the second sidewall is set to zigzag fashion.
Peaking wave wall on described the first side wall and the second sidewall is formed by Laser Processing or passes through punching press
Instrument is stamped and formed out.
The beneficial effects of the present invention is:
Be formed at the first side wall of cannula body portion endless groove, the second sidewall constitutes reflecting surface, can generate relative to ultrasound wave
Incidence wave be parallel echo, it is possible to clearly obtain from ultrasonic probe injection ultrasound wave formed needle tubing image,
The position of accurate assurance puncture needle.
Accompanying drawing explanation
Fig. 1 is the top view of puncture needle of the present invention.
Fig. 2 is the front view of puncture needle of the present invention.
Wherein: 1, cannula body portion 11, cavity 12, endless groove 121, axis 13, the first side wall 131,
The crest 132 of the first side wall, the crest 142, second of trough the 14, second sidewall the 141, second sidewall of the first side wall
The trough 2 of sidewall, syringe tip.
Detailed description of the invention
The invention will be further described with detailed description of the invention below in conjunction with the accompanying drawings.
A kind of puncture needle as shown in Figure 1 and Figure 2, including cannula body portion 1 and syringe tip 2, described cannula body portion 1 wraps
Containing a cavity 11, cavity 11 connects with syringe tip 2, and described syringe tip 2 is the inclined plane with a tip, described needle tubing master
Being formed with endless groove 12 on body 1, the bottom of the first side wall the 13, second sidewall 14 forming endless groove 12 is intersected, and described first
Sidewall 13 and the second sidewall 14 are respectively formed on the wall of peaking wave, and relative to the axis 121 of described endless groove 12
The crest 131 of the first side wall 13 is oppositely arranged with the crest 141 of the second sidewall 14, the trough 132 of the first side wall 13 and the second side
The trough 142 of wall 14 is oppositely arranged；This kind of setting ensure that no matter puncture needle from which direction penetrates, can be clearly
Imaging；Angle a that the bottom of described the first side wall 13 and the second sidewall 14 is formed is at least 30 degree, so that the first side wall 13 and the
Peaking wave on two sidewalls 14 can form good echo, it is preferable that angle a is set to 60 degree；By described
Peaking wave wall on one sidewall 13 and the second sidewall 14 is set to zigzag fashion, preferably to form echo, preferably
Ground, is set to symmetrical point of the axis 121 along endless groove 12 by the zigzag fashion wall on the first side wall 13 and the second sidewall 14
