Description
Technical Field
The utility model relates to the field of medical supplies, specifically be an intervertebral disc radio frequency melts puncture location auxiliary device.
Background
The lumbar intervertebral disc protrusion is a common disease and frequently encountered disease in clinic, and the treatment of the disease mainly comprises conservative treatment, interventional treatment, minimally invasive treatment, open non-fusion and fusion treatment. The traditional open surgery may have blood vessel, nerve root and cauda equina injuries, and the surgery may have infection, epidural fibrosis and scar formation, and may even develop into lumbar vertebra surgery failure syndrome. The minimally invasive interventional therapy is accepted by patients due to the characteristics of small wound, less bleeding, short operation time, quick postoperative recovery and the like, and is rapidly developed in the field of spinal surgery. Among them, low-temperature plasma radiofrequency ablation nucleus pulposus forming operation is widely applied to treating mild and moderate lumbar intervertebral disc protrusion because of obvious curative effect, high safety and the like.
The low-temperature plasma radiofrequency ablation technology breaks organic molecular bonds of nucleus pulposus tissue through kinetic energy generated by radiofrequency energy, vaporizes the organic molecular bonds into oxygen, hydrogen, carbon dioxide and the like, can be discharged or absorbed by tissues through a cannula, and then reaches about 70 ℃ through the thermal effect generated by tissue resistance, so that the nucleus pulposus tissue is contracted and solidified. Research shows that the pressure of the intervertebral disc can be reduced by 10 to 20 percent when 1ml of intervertebral disc tissues are ablated. The annulus fibrosus is collapsed by intradiscal decompression to achieve the purpose of decompression of the tissues surrounding the intervertebral disc (nerve roots, arteries, spinal cord, etc.). In addition, CN may also act by altering the expression of inflammatory cytokines in degenerated discs (e.g., reducing interleukin 1 production, promoting interleukin 8 production, etc.).
The operation has the characteristics of small wound, low risk, obvious operation effect and the like. However, due to the self-restriction, most hospitals choose to complete the operation under the guidance of a C-arm machine. Because of the inability to precisely position, C-arm machine-guided rf ablation can only directly ablate the central region of the disc, relieving the disc from compression on the nerve root by indirect decompression by relieving the pressure in the center of the disc, and is not the optimal choice for treatment. And CT guide can be directly and accurately positioned in the operation, so that the puncture target point is closer to the disc herniation area, and the rest normal tissues can not be damaged too much while direct decompression is realized. However, there are two drawbacks to CT: firstly, the ray quantity in one fluoroscopy is large; secondly, the time required for one-time perspective is longer than that of a C-arm machine. For doctors with insufficient operation experience, repeated puncture and fluoroscopy are needed, and the needle insertion angle is adjusted, so that the operation time is prolonged, the soft tissue is damaged too much, the risk of blood vessel injury is increased, and the radiation receiving amount of a patient is increased. It is not uncommon for operators to be demanding, extremely difficult to handle, and without associated ancillary tools. The development of the radio frequency ablation is greatly limited, more and more patients with lumbar intervertebral disc protrusion have no medical search, so the condition of the disease is delayed, the disease is aggravated, irreversible serious consequences are caused, economic loss is caused, and the social medical burden is aggravated. Therefore, the popularization of the operation is imperative, and in order to solve the difficulty, the positioning device for the intervertebral disc low-temperature plasma radio frequency ablation operation can effectively guide the puncture needle insertion angle and strive for one-time perspective to reach the target point.
