Operation principle of the present utility model is that ablation is combined with heat setting to remove part nucleus pulposus and make nucleus pulposus group
Contraction is knitted, to reduce the volume of nucleus pulposus and reduce the pressure in interverbebral disc.The 100kHz formed by welding tip 2
Strong rf electric field makes the electrolyte of its head be converted into plasmoid, forms about 50-100 μm of plasma thin layer,
These free charged ions obtain the kinetic energy of the organic molecule key interrupted enough in tissue under strong magnetic field, so that around causing
The gasification of nucleus pulposus, generation molecular weight gas and element molecule (02、H2、C02Deng), to nucleus pulposus group in a low temperature of about 40 DEG C
Knit to form cutting and ablation effect, therefore the technology is also known as " cold melt cuts ".Because operating temperature is at 40 DEG C or so,
While removing pathological tissues irreversible damage will not be produced to the normal structure of surrounding.When energy is relatively low, organize to penetrating
The resistance of frequency increases, so as to produce fuel factor, " heat setting closing " effect is produced at a temperature of about 70 DEG C, had both made the glue in nucleus pulposus
Former protein molecular helical structure vaporization is shunk and solidified, and the vigor of nucleus pulposus cell can be kept again, the cumulative volume of interverbebral disc is reduced, from
And the pressure in interverbebral disc is reduced, stimulation of the disc tissue to nerve root is alleviated, with relief of symptoms, makes collagen molecules
Helical structure shrinks, and further makes nucleus pulposus volume-diminished, reaches that volume reduction is depressurized, releases the pressure to dura mater and nerve root
Compel to reach therapeutic purposes.
