Description
Technical Field
The invention relates to the field of medical instruments, in particular to a intervertebral space distraction sleeve device for a split expandable percutaneous spine endoscope.
Background
The lumbar degenerative disease is a spinal mid-axis osseous organic lesion caused by age increase and injury accumulation, mainly affects nerve structures in intervertebral discs, ligaments and vertebral canals, including a series of diseases such as lumbar disc herniation and lumbar spinal stenosis, and often causes limb pain, numbness and weakness, even paralysis, and influences normal life and work of patients. The disease has complex pathogenic mechanism, high morbidity and wide sick population, is a frequently encountered disease which troubles the health of human beings and becomes the main reason of medical expenditure, absenteeism and disability of the masses. Especially, the morbidity of physical workers in rural areas is higher. Patients with lumbar degenerative diseases with poor conservative treatment effect often need surgical treatment. The prior surgical treatment is mainly open surgery, and has good clinical curative effect, but the traditional surgical treatment has large trauma, much bleeding and slow postoperative recovery, and the damage of the normal spinal structure caused by iatrogenic property in the operation often causes or aggravates the body injury. How to reduce surgical trauma, reduce complications and accelerate patient recovery while ensuring good treatment effect is a world problem to be solved urgently in the field of orthopedics.
The minimally invasive surgery is the key to solve the problems, and the endoscopic open spine surgery is an important way to realize the minimally invasive surgery. An aqueous medium spinal endoscope operating system developed by Anthony Yeung in 2000 is implanted into an operating sleeve with the diameter of about 7mm through a small skin incision and a muscle soft tissue and a lumbar intervertebral foramen, is implanted into a spinal endoscope and an operating instrument through the operating sleeve to perform discectomy decompression, reaches a protruded nucleus pulposus part and performs accurate discectomy, has small surgical trauma, is called a spinal minimally invasive surgery technology with real meaning, and lays the foundation of the modern percutaneous spinal endoscope operation technology. However, because the original natural clearance of the spinal intervertebral space is small, the existing spinal endoscope operation channel is integrated, the internal channel is small, and the application of the technology is greatly limited due to the difficulty in passing through the existing intervertebral fusion device and instrument with matched specifications. In addition, the original operating sleeve device is circular, so that for patients with serious degeneration, intervertebral space reduction and nerve clamping tissues are reduced, intervertebral space expansion is needed in the operation, and an intervertebral fusion device is implanted into bone fusion to maintain the sequence and the stability of the spinal segment, and the conventional spinal endoscope technology cannot be applied to operation.
