Description
Technical field
The utility model relates to the field of medical instrument technology, especially a kind of ultrasonically enhanced neural radio frequency needle.
Background technique
Neural radio frequency needle is the consumptive material of neural RF therapy indispensability, is punctured near target nerve, makes using neural radio frequency needle
Organization internal friction of motion heat, selectivity damage nociceptive nerve fibres and lead branch, and pain signal is blocked to pass to upper nerve signal
It leads, makes pain signal that can not pass to brain, sensation of pain and experience cannot be generated, to achieve the purpose that control pain.
During neural RF therapy, radio frequency needle whether can disposable wearing to target nerve near, directly affect treatment
Effect.If radio frequency needle punctures the damage that can bring surrounding tissue, infection not through correct region repeatedly, and may cause
The damage or function for closing on other nerves are lost, and the severe complications such as numb, pain exacerbation, the paralysis of even muscle are caused.
Ultrasonic guidance is the important image-guided mode of one kind of neural radio frequency, has real-time dynamic guiding, radiationless etc.
Advantage.So far, a variety of neural radio frequency needles have been developed all over the world, have also thought that many methods make it possible to by ultrasonic real
When show, however actual effect is often not satisfactory, and is influenced, penetrates by many reasons such as needle angle, tissue depth, front decaying
Frequency needle shows still dissatisfied.
Utility model content
For the problems of above prior art, the purpose of the utility model is to provide a kind of ultrasonically enhanced nerves
Radio frequency needle, it is simple and reasonable, ultrasonic guidance display effect can be enhanced, promote the accuracy of radio frequency needle guiding in real time, guidance
It punctures into around target nerve, so that the function of puncturing the damage that can bring surrounding tissue, infection and nerve repeatedly is avoided to lose,
Mitigate patient suffering, improves the success rate for the treatment of.
To achieve the goals above, the technical solution of the utility model is:
A kind of ultrasonically enhanced neural radio frequency needle comprising have: syringe needle, needle be dry, backshank and connects with the backshank signal
The neural radiofrequency generator connect, wherein the dry surface of the needle has the multi-segment thread unit of spaced set；The threaded elements
Flank angles are 90 °.
As a kind of specific embodiment, the head and the tail total length of threaded elements described in multistage is 30~50mm.
Further, the aggregation length of one section of threaded elements sum is 10mm；One section of threaded elements includes 20
Enclose thread.
Further, the spacing between adjacent two sections of threaded elements is 1mm.
As a kind of specific embodiment, closest to the point of that section of threaded elements and the syringe needle of the syringe needle
Spacing between end is 3mm.
As a kind of specific embodiment, the syringe needle is flat construction.
As a kind of specific embodiment, the syringe needle is bending structure.
The ultrasonically enhanced neural radio frequency needle of one kind of the utility model has following advantageous effects compared with the prior art:
When ultrasonic wave is transmitted to the threaded elements, since the flank angles of the threaded elements are 90 °, it is directed to described
Ultrasonic wave on threaded elements can rebound along ultrasonic wave incident direction opposite direction, and echo-signal is splendid, thus ultrasonic image is more
It is bright, it shows apparent；Threaded elements spaced set described in multistage is conducive to real-time then convenient for threaded elements described in positioning single hop
Grasp the position of the nerve radio frequency needle.The technical program promotes the accuracy of radio frequency needle guiding in real time, so that operation is more accurate
Reliably, operation risk and the pain of patient are reduced significantly.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.

Specific embodiment
Embodiment 1
Please refer to Fig. 1 and Fig. 2, a kind of ultrasonically enhanced neural radio frequency needle comprising have: syringe needle 1, needle be dry 2, backshank 2 with
And the neural radiofrequency generator 5 being connect with backshank 2 by 4 signal of connecting line, the surface of needle dry 2 have 5 sections of screw threads of spaced set
Unit 6；The flank angles of threaded elements 6 are 90 °.Wherein, the head and the tail total length of multi-segment thread unit 6 is 50mm.One section of screw thread
The aggregation length of 6 sum of unit is 10mm；One section of threaded elements 6 includes 20 circle threads；Between between adjacent two sections of threaded elements 6
The length of vacancy 7 away from formation is 1mm.Closest to syringe needle 1 that section of threaded elements 6 and syringe needle 1 tip between spacing
For 3mm.In the present embodiment, syringe needle 1 is flat construction, is suitable for specific corresponding human body lacuna.
When ultrasonic wave is transmitted to threaded elements 6, since the flank angles of threaded elements 6 are 90 °, it is directed to threaded elements 6
On ultrasonic wave can rebound along ultrasonic wave incident direction opposite direction, echo-signal is splendid, thus ultrasonic image is brighter, display more
Clearly；6 spaced set of multi-segment thread unit, while the spacing between the tip of syringe needle 1 and most proximity its threaded elements 6 is
3mm, aforementioned vacancy 7 are used as location graduation, convenient for positioning single hop threaded elements 6, conducive to the position for grasping the nerve radio frequency needle in real time
It sets.The technical program promotes the accuracy of radio frequency needle guiding in real time, so that operation is more accurate and reliable, reduces operation significantly
The pain of risk and patient.
