Lumbar vertebrae is formed by the centrum of bone and than more flexible interverbebral disc, has spinal cord and spinal nerve at their rears, is responsible for
Waist sensorimotor below and stool and urine etc..Normal condition lumbar discectomy by fibrous ring remain attached to vertebral rim with
Interior, along with the cerebrospinal fluid around spinal cord contains, interverbebral disc does not have any contact with spinal cord and nerve root.Human body lumber ertebral disc exists
Start regression, dehydration after 30 years old, corresponding surrounding fibrous ring, rear zygapophysial joint suffered by stress increase, in external force
Under constantly squeezing, lumber ertebral disc outer layer fiber ring breakage, nucleus pulposus is prominent from rent, and compressing or stimulation nerve root lead to waist stern
Portion's pain (referred pain) and leg pain (Rediating Pain).
The basic principle of low temperature plasma procedures electrode is the energy generated using plasma generator, makes plasma
The plasma thin layer of high aggregation is formed between body procedures electrode and tissue, the plasma in thin layer is had by electric field acceleration
Organic molecule chain in enough energy comminution tissues makes the simple molecule of tissue breakdown, atom or low-molecular-weight gas, from
And reach the function of ablation cutting.Under C-arm or CT guidance, puncture needle is inserted into interverbebral disc by doctor from triangle of safety area,
Then interverbebral disc is acted on by Plasma surgical electrode, it, can will be to mind by melting repeatedly by surrounding them ablation of tissue
It is caused the tissue of compressing all to gasify to excrete.Entire ablation procedure electrode temperature maintains 70 DEG C, leaves electrode 1mm temperature
Degree is reduced to 40 DEG C, so a possibility that causing damage to peripheral nerve is very small.Plasma surgical can also be utilized simultaneously
The cooling solidification of electrode acts on, and makes to melt channel circumference tissue shrinkage, solidification, prevents nucleus pulposus from protruding again along ablation channel.
Traditional lumbar vertebrae Plasma surgical electrode ablation area is small, is difficult that the tip of procedures electrode is allowed to reach target spot position
It sets, influences the operability and practical effect of operation.
Utility model content
Technical problem to be solved in the utility model and the technical assignment of proposition are improved to the prior art, are provided
A kind of lumbar vertebrae Plasma surgical electrode, solve lumbar vertebrae Plasma surgical electrode in current technology is difficult to reach target spot position
It sets, the problem of surgical effect difference.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of lumbar vertebrae Plasma surgical electrode, including electrode and puncture needle, which is characterized in that the electrode is in elongated
Structure, and the tip of electrode is in bending structure, and puncture needle enters needle by the triangle of safety area of lumbar vertebrae, and electrode penetrates the needle of puncture needle
The minim channel that pipe is formed enters nucleus pulposus.Lumbar vertebrae Plasma surgical electrode described in the utility model uses the electricity of tip bending
It is extremely melted, is accessible to target position, circumferentially rotating electrode, electrode can realize that range melts, can will to nerve
It causes the tissue of compressing all to gasify to excrete, while melting channel circumference tissue shrinkage, solidification, prevent nucleus pulposus edge from disappearing
Circulation road protrudes again.
Further, the bending angle of the eletrode tip is 16 degree, large range of bending may be implemented, thus complete
It is melted at target spot.
Further, the needle tubing tip of the puncture needle is in bending structure, can individually rotate puncture needle or electrode, or
Person rotates puncture needle and electrode simultaneously, and large range of bending may be implemented in eletrode tip in nucleus pulposus, disappears to complete target spot
Melt.
Further, the needle tubing tip bending angle of the puncture needle is 8 degree, and ablation area is big, and realizes larger
The bending of range.
It further, further include guide pin, the guide pin penetrates in the needle tubing of puncture needle, and the tip of puncture needle is located at
In the fibrous ring of lumbar vertebrae, it is oriented to needle-penetration fibrous ring, further takes out guide pin, electrode is enabled easily to enter nucleus pulposus, guide pin
The function of fibrous ring is passed through in completion.
It further, further include syringe needle, after the completion of electrode is implemented to melt, syringe needle penetrates the needle tubing of puncture needle to disappearing
Melt place's injection Collagenase.
Compared with prior art, the utility model advantage is:
Lumbar vertebrae Plasma surgical electrode described in the utility model, structure is simple, compact, tip bending electrode with wear
Pricker cooperation, may be implemented large range of bending, to complete target spot ablation, not only eliminate sufferer, but also maintain interverbebral disc
Normal function, ablation area it is big, it is ensured that can will to nerve cause compressing tissue all gasification excrete, improve operation effect
Fruit.
