Description

Technical Field

[0001] The invention belongs to the technical field of surgical devices, and in particular relates to an ablation electrode used under an endoscope. Background Art

[0002] Existing medical institutions are still using existing high-frequency electrosurgical equipment to perform deep spinal surgery. High-frequency electrosurgical equipment uses high-power electron tubes, high-power transistors, and UOS tubes to generate high-frequency oscillations, emitting penetrating high-frequency power to generate extremely high temperatures in human or animal tissues, causing cell tissues to rupture or coagulate, achieving surgical effects. However, during deep spine surgery, excessive temperatures can damage the spinal cord and cells, which is extremely detrimental to the surgery. Therefore, high-frequency electrode surgical equipment is not suitable for continued use in such surgeries. Therefore, radiofrequency ablation electrodes came into being, with a specific operating frequency of ≥1.2MHz, up to 41.2MHz. The bipolar power is ≥50W and can reach a maximum of 300W, so that the temperature generated by the product generally does not exceed 70℃, and difficult spinal surgeries can be successfully completed at a controllable temperature, greatly improving the safety and reliability of the surgery and simplifying the doctor's operation process. Perforaminal endoscopic lumbar disc surgery is recognized by industry experts as a "minimally invasive spinal surgery". The surgery can treat lumbar disc herniation and relieve compression without surgery or destroying the stability of the spinal canal, allowing patients with lumbar disc herniation to get rid of pain. Due to the rapid development of the medical industry, the difficulties of traditional high-frequency output equipment in minimally invasive spinal surgery have gradually become prominent.

The electrode wire 9 transmits the radio frequency energy in the spinal coagulation mode to the first electrode sheet 11 and then passes through the human body and returns to the radio frequency device through the second electrode sheet 12, forming a complete circuit to complete the spinal coagulation of the patient's operated part;

[0029] When using domestic radio frequency equipment for surgery, the present invention is connected to the domestic radio frequency equipment through the second plug, and then the radio frequency equipment is turned on. The user of the present invention pinches the handshake 13, and the handshake 13 drives the first handle 1 to move to the right. The first handle 1 squeezes the spring 7 to the right, and the spring 7 drives the push block 8 to move to the right. The push block 8 pushes the two electrode wires 9 to move to the right along the insulating sleeve 3. The electrode wire 9 pushes the electrode head 10 and the first electrode sheet 11 and the second electrode sheet 12 at the right end of the electrode head 10 to move to the right and extend the insulating sleeve 3 to the right. Then the user of the present invention uses the endoscope equipment to extend the present invention into the patient's surgical site to perform surgery on the patient. When the patient needs to undergo ablation cutting, the ablation cutting mode of the domestic radio frequency equipment is turned on. Then, the domestic radio frequency equipment transmits the radio frequency energy under the ablation mode cutting mode to the second wiring block through the second plug, and then transmits it to the electrode wire 9 located in the rear mounting cavity through the second wiring block. The electrode wire 9 transmits the radio frequency energy under the ablation cutting mode to the first electrode sheet 11 and then passes through the human body and returns to the radio frequency equipment through the second electrode sheet 12, forming a complete The complete circuit completes the ablation and cutting of the patient's operated part; when the patient needs spinal ablation, the spinal ablation mode of the domestic radio frequency device is turned on, and then the domestic radio frequency device transmits the radio frequency energy in the spinal ablation mode to the second wiring block through the second plug, and then transmits it to the electrode wire 9 located in the rear installation cavity through the second wiring block.

The electrode wire 9 transmits the radio frequency energy in the spinal coagulation mode to the first electrode sheet 11 and then passes through the human body and returns to the radio frequency device through the second electrode sheet 12, forming a complete circuit to complete spinal coagulation of the patient's operated part;

[0030] After the operation is completed, the present invention is removed from the domestic or imported radio frequency device, the disposable application chip in the first plug and the second plug of the present invention is prevented from being reused, and then the present invention is sent to the recycling location for centralized processing of the present invention;

[0031] The operating frequency of the host of domestic or imported radio frequency equipment is generally 1.2MHz~4MHz, and the bipolar power is ≥50W. It can treat spondylolisthesis within 2 degrees, spinal infectious diseases (tuberculosis, brucellosis, postoperative infection, etc.), spinal instability, endplate inflammation, spondylosis, intervertebral disc herniation and lumbar spinal stenosis. It combines fusion and non-fusion technology to form a combined minimally invasive technology, which can intervene in spinal stability and form a combined minimally invasive surgery that retains the middle and posterior columns to achieve ideal surgical results.

[0032] The radio frequency energy output flows through a relatively long distance through a roughly equal or smaller diameter on the human organ, and the human tissue is first heated at the smallest diameter part. If the radio frequency energy output current flows through the same diameter over a relatively long distance, the human tissue can be coagulated at the entire contact part. The present invention can fully release the function of radio frequency ablation. Conventional high-frequency ablation electrodes are short and the electrode heads are exposed too much. There is a risk of releasing energy when passing through other parts of the human body, and they cannot reach the predetermined surgical site, and cannot release the best effect of radio frequency equipment.

[0033] The present invention can accurately remove the protruding nucleus pulposus when used, can directly ablate the nucleus pulposus and repair the ruptured annulus fibrosus at low temperature, can perform ozone injection through a special ozone-resistant channel after surgery to instantly relieve the edema and aseptic inflammation of the nerve roots, and effectively prevent postoperative intervertebral disc infection. The corresponding target is directly targeted during the operation, and minimally invasive surgery allows patients to have less surgical trauma, less pain, a wide range of indications, good long-term efficacy, and flexible operation. It is easy to learn and use, can handle all types of intervertebral disc herniation, distinguish between spinal canal stenosis, intervertebral foraminal stenosis, calcification and other bone lesions, and has high safety 1. Low surgical risk. The surgery can be performed under local anesthesia. The patient can interact with the patient during the operation. Nerves and blood vessels will not be injured. There is little bleeding. The surgical field of view is clear, which greatly reduces the risk of operational errors. The patient can recover quickly and can walk the next day after the operation. It takes an average of 3-6 weeks to resume normal work and physical exercise. The patient has a high satisfaction rate in the later stage. The pain can be relieved quickly, and the patient can take care of his own urination and defecation. The care is simple. Outpatient surgery is feasible. The skin incision is only 7mm, which conforms to the aesthetic point of view and has a wide range of expansion. Combined with percutaneous fixation technology, it can complete the fusion and fixation of spinal slippage and instability in a minimally invasive way.
