Description

Wicresoft's electronic intervertebral disc decompression apparatus

Technical field

This utility model relates to a kind of medical equipment, especially relates to a kind of Wicresoft electronic intervertebral disc decompression apparatus.

Background technology

Intervertebral disc is between human spine's two cones, a seal of being made up of cartilaginous lamina, fibrous ring, vertebral pulp.Cartilaginous lamina is arranged up and down, is that hyaline cartilage is covered on the vertebral body, below the intermediary surface of bone of epiphysis ring.Cartilaginous lamina up and down seals vertebral pulp with fibrous ring.Fibrous ring is made of the fibrous cartilage of collagenous fiber bundle, be positioned at vertebral pulp around.The mutual diagonal juxtaposition of the fibre bundle of fibrous ring makes fibrous ring become solid tissue, can bear bigger bending and torque load.

Degeneration promptly appears in various the organizing of human body after the adolescence, wherein the variation of intervertebral disc takes place early, the main variation is nucleus dehydrates, dehydration back intervertebral disc loses its normal elasticity and tension force, on this basis because heavier wound or repetitious not obvious damage, cause fibrous ring weak or break, vertebral pulp is promptly outstanding by this place, pressuring neural root and produce injured nerve root and hinder sign; The front side and the both sides of fibrous ring are thicker, and rear side is thinner.There is powerful anterior longitudinal ligament the front portion of fibrous ring, and the posterior longitudinal ligament of rear side is narrower, thinner.Therefore, vertebral pulp is rearward outstanding easily, pressuring neural root or spinal cord.

In recent years, adopt the method treatment intervertebral disk hernia of getting involved to obtain very large progress in the world.(lumbar disc prolapse, LDP) interventional therapy was risen in the 60 to 70's prolapse of lumbar intervertebral disc.Along with technological progress, new technology continues to bring out, and has obtained the achievement that attracts people's attention aspect clinical treatment.The common feature of this class Therapeutic Method is that operation wound is little, does not destroy the normal configuration of spinal column. complication is few, and appropriate as long as indication is selected, therapeutic effect is good, and patient is painful few, recovers fast. spend little.

Prolapse of lumbar intervertebral disc (lumbar disc prolapse, LDP) principle of its treatment of interventional therapy can be divided into several classes basically:

One class be chemical decompression (chemonucleolysis, CN): comprise that chymopapain (abbreviation carase), collagen hydrolysate enzyme (abbreviation collagenase) and medical ozone (03-02mixture) carry out the interior injection for curing LDP of intervertebral disc.Their effect substrate has nothing in common with each other.Carase acts on the noncollagen protein of proteoglycan aggregate, has molecular weight and stickiness, the mucinous polymerization of destruction and the water absorption of water soluble protein in the rapid minimizing vertebral pulp, causes the nucleus dehydrates contraction, and it is intrinsic pressure to reduce intervertebral disc.Then I, the II Collagen Type VI in hydrolysis vertebral pulp and the fibrous ring is white specifically for collagenase, vertebral pulp is degenerated and reaches the decompression purpose; After ozone injects vertebral pulp, its strong oxidation can directly destroy proteoglycan and the nucleus pulposus cell in the nucleus pulposus matrix, also may be by destroying the normal configuration of proteoglycan, make the proteoglycan afunction, synthesis secretion reduces, its consequence and carase are similar, and this is the main effect of ozone therapy intervertebral disc prolapse.Remove this, ozone still can stimulate the antioxidase overexpression with in and in the aseptic inflammation reaction (due to the intervertebral disk hernia) excessive active oxygen (ROS) but, promote release of cytokines with the antagonism inflammatory reaction, promote vasodilation to be beneficial to inflammatory resolution to absorb. the dissipation of inflammation absorbs alleviating neuropathic pain again.In addition, Boci[7] infer that ozone may activate the anti-damage system of body, stimulate inhibitory interneuron to discharge enkephalin and play analgesic activity; By the antiinflammatory and the analgesic activity of ozone, but mitigation symptoms promotes to recover.

Second class is the disc tissue gasification and decompression: mainly contain radio-frequency (RF) ablation vertebral pulp urethroptasty (Nucleoplasty, NP) and percutaneous laser vaporization art (percutaneous laser discdecompress ion, PLDD).Radio-frequency (RF) ablation vertebral pulp urethroptasty mainly send radio-frequency (RF) energy (125Vrms) in intervertebral disc by special-purpose bipolar radio frequency vaporization rod by the most advanced and sophisticated plasma blade hair of rod, thereby acquisition acceleration, interrupt the organic molecule key of nucleus pulposus, thereby vaporization part of intervertebral disc nucleus pulposus, form efficient accurate vaporization and melt and cuts effect, via the cold macromole of cutting be resolved into elements molecule, the low molecular weight gas (oxygen, nitrogen, hydrogen, carbon dioxide) of melting.And then auxiliary heat solidification technology, utilization is heated to about 70 ℃, the collagen molecules helical structure is shunk, further make nucleus pulposus volume-diminished (dwindling 0.94cm3 altogether approximately) in 6 ducts, gap of lumbar vertebra, reach and subtract capacitive decompression, remove compressing to dura mater and nerve root then to reach therapeutic purposes.Percutaneous laser vaporization art enlarges the space of nucleus pulpous cavity mainly by the gasification nucleus pulposus, makes that nucleus pulposus solidifies, carbonization, and it is intrinsic pressure to lower lumbar intervertebral disc, impels outstanding nucleus pulposus Hui Na.

The 3rd class is that apparatus is extractd decompression, promptly extracts nucleus pulposus by special instrument.The nucleus pulposus that the intervertebral disc centre could " be windowed ", extract to these class methods by fibrous ring is intrinsic pressure to reduce intervertebral disc, promote outstanding nucleus pulposus retraction, reach the purpose of indirect decompression, main method have percutaneous puncture lumbar discectomy art (percutaneous lumbar discectomy, PLD); Also there is the people that second class and the 3rd roughly the same is classified as physical property decompression class.

The operation of new class is the electronic intervertebral disc decompressor of Wicresoft, be that recent years are in the up-to-date operation at protrusion of lumber vertebral disc in vogue of the U.S., this is performed the operation in the process of implementing owing to the material of intervertebral disk hyperplasy can be taken out, belong to the Minimally Invasive Surgery class simultaneously, so be unique a kind of intervertebral disc operation method that can access AIA's approval in the U.S. at present, obtained simultaneously the U.S. FDA approval, this product is through domestic and international relevant expert's demonstration, be best a kind of in the intervertebral disc operation, but because this operating equipment expense height, and only suitable disposable use, therefore increased the cost of apparatus, made that introducing domestic being difficult to popularizes.
