Lumbar disc herniation is due to the degeneration of the intervertebral disc, the nucleus pulposus protrudes after the rupture of the annulus fibrosus and compresses the nerve root, resulting in low back pain as the main manifestation of the disease, it is one of the more common lumbar disorders in clinical practice, and in recent years its incidence has been on the rise year by year. Its treatment is divided into non-surgical treatment and surgical treatment, non-surgical treatment is less traumatic, high security, mostly for bulging type, herniation of mild type, no obvious spinal stenosis type, for the early lumbar disc herniation patients can get a better clinical treatment; surgical treatment is suitable for patients with more serious condition, surgical indications require high, difficulty and risk is relatively large, and postoperative complications are more. Therefore, surgical treatment is increasingly moving towards the trend of minimally invasive, low-risk, less painful and faster recovery. At present, clinical minimally invasive percutaneous disc aspiration resection, whose treatment can reduce the pressure within the intervertebral disc, reduce the tension of the posterior longitudinal ligament and the annulus fibrosus, and prompt the herniated material to retract, thus eliminating or alleviating the compression on the nerve root, and with the advantages of low risk, low pain, and fast recovery, has been widely used in the clinic. However, due to the percutaneous disc suction and excision puncture path with the spinal column and spinal cord obstruction, the resection instruments used in the operation are all in the direction of the protruding nucleus pulposus to form an angle, which can not be directly clamped on the local protruding nucleus pulposus tissue and retracted back to reset, so for the patients with protruding discs that have already ruptured the annulus fibrosus, the efficacy of this treatment is poor, or even ineffective. At present, we use “modified percutaneous lumbar disc aspiration resection” – that is, the use of percutaneous lumbar disc aspiration resection decompression, combined with controllable steering forceps (homemade) to directly extract and retract the local protruding nucleus pulposus tissue can play a better clinical efficacy, expanding the percutaneous lumbar disc aspiration resection. Clinical efficacy, expanding the clinical indications of percutaneous lumbar disc suction excision, is a minimally invasive treatment of lumbar intervertebral disc herniation without surgery is another innovation, the patient can be discharged after one week of hospitalization, the advantages of: 1, minimally invasive, 2, safety, 3, fewer complications, 4, fast recovery, 5, low cost of treatment and so on.
