Endoscopic disc removal and radiofrequency decompression Endoscopic radiofrequency decompression means that under the guidance of C-arm X-ray machine, with the help of minimally invasive intervertebral foramoscope, under local anesthesia and consciousness of the patient, a working channel for nucleus pulposus is established by breaking through the intervertebral foraminal safety triangle and entering the intervertebral disc, and then minimally invasive special nucleus pulposus forceps combined with bendable bipolar radiofrequency are used to remove and ablate the herniated nucleus pulposus, so that the herniated nucleus pulposus is The herniated nucleus pulposus is removed or smashed and sucked out, so that the nerve root compression is released, thus achieving the purpose of treating the herniated disc. The incision is less than 7mm, the operation time is short, the bleeding is low, the cost is low, and generally the patient can get out of bed and walk after the operation is completed, and the symptoms of back and leg pain disappear completely. Minimally invasive internal fixation Minimally invasive internal fixation technology refers to the establishment of minimally invasive small incision surgical environment through puncture positioning under the guidance of C-arm X-ray machine and through special access system, light source system and surgical instruments, which can reduce surgical bleeding, reduce surgical trauma and avoid nerve damage due to frequent intraoperative pulling in open surgery as much as possible without affecting the surgical effect. Reduce the risk of surgery and anesthesia, and shorten the patient’s postoperative recovery time. Clinical studies have shown that this technique has the advantages of less bleeding, less trauma, fewer neurological complications, faster recovery, and significant efficacy. At present, minimally invasive internal fixation techniques of the spine are classified according to the surgical access: minimally invasive posterior lumbar interbody fusion (MIS-PLIF), minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF), lumbar lateral approach fusion through the psoas major muscle (DLIF), extreme lateral interbody fusion (XLIF), and small incision anterior lumbar interbody fusion (MINI-ALIF). The selection of the appropriate treatment plan for different patient conditions is of great importance to the patient’s surgical outcome and prognosis. Minimally invasive percutaneous spinal system techniques include interventional treatments such as balloon-expandable vertebroplasty (PKP/PVP), laser, collagenase, ozone, excisional aspiration, and low-temperature plasma radiofrequency ablation (Coblation). Minimally invasive treatment of spinal tuberculosis Spinal tuberculosis seriously endangers the health of patients, and even paraplegia endangers the lives of patients, the advantages of open surgery is more thorough treatment, more mature technology. The advantages of open surgery are that the treatment is more thorough and the technology is more mature, but the disadvantages are high risk, bleeding, long recovery time and high cost. Minimally invasive surgery means that the pus is extracted from the lesion under local anesthesia and the patient is conscious under CT guidance, and a tube is placed to inject drugs into the lesion to increase the concentration of local anti-TB drugs and promote the healing of the lesion.
