Transforaminal nanometer-bioglass-coating minimally-invasive fusing device

Abstract

The invention discloses a transforaminal nanometer-bioglass-coating minimally-invasive fusing device. The minimally-invasive fusing device comprises a body stretching net, and the surface of the body stretching net is coated with an ordered nanometer-mesoporous biological activity glass coating. The body stretching net is formed by cobalt-chromium alloy wires. A nanometer biological glass coating material is prepared from SiO2 sol, CaO sol and P2O5 sol, attachment of osteoblast and growing of blood vessels can be achieved through the biological glass coating, and bone fusion between centrums is promoted. The minimally-invasive fusing device can be applied to the lumbar vertebra fusing technology conducted under a foramen intervertebrale mirror. The transforaminal nanometer-bioglass-coating minimally-invasive fusing device has the advantage of being extensible in minimally invasive technology, is used in cooperation with a saccule, the saccule and the net-shaped fusing device with which the surface of the saccule is covered are expanded at the same time, intervertebral space with narrow reset is opened, extension of the net-shaped fusing device along the outline of an end plate reaches the estimated height, then the elliptic-cylinder-like shape is shown, the obtained the net-shaped fusing device and the outline of an end plate are completely matched, the saccule is pulled out, the fusing device is reserved in the intervertebral space, the intervertebral space is supported, and the transforaminal nanometer-bioglass-coating minimally-invasive fusing device can be applied to the lumbar vertebra fusing technology conducted under the foramen intervertebrale mirror for curing lumbar spine instability.

Description

Technical field [0001] The invention is a treatment device mainly used in spinal minimally invasive surgery, and belongs to the technical field of medical device manufacturing. Background technique [0002] Lumbar disc herniation is a common and frequently-occurring disease in orthopedics. Most cases of lumbar disc herniation that require surgery can be resolved by percutaneous endoscopic lumbardiscectomy (PELD). Minimally invasive percutaneous endoscopic lumbar discectomy has opened up a new way for the treatment of lumbar disc herniation. It has the advantages of less damage to the spine structure, less interference with the spinal canal, limited surgery, and minimal invasiveness. Patients can get out of bed early Activities significantly improve the quality of life. Minimally invasive percutaneous endoscopic lumbar discectomy usually uses the following procedures: ①YESS (Yeung Endoscopic Spine System) technology; ②TESSYS (Thomas Hoogland Endoscopy SpineSystems) technology; ③E...

AI Technical Summary

Problems solved by technology

Among them, the first two surgical methods are suitable for cases of simple lumbar disc herniation, but some cases often have narrow intervertebral space and lumbar instability before operation. Simply removing the intervertebral disc will increase the instability of the lumbar spine. Spinal fusion, EndoLIF transforaminal endoscopic lumbar interbody fusion came into being

[0003] In the past, there were reports at home and abroad that the B-Twin expandable intervertebral fusion device of the Israeli company was used for percutaneous lumbar interbody fusion. The stress is high and it is easy to herniate into the vertebral body, so the clinical application of this fusion device is less and less

In recent years, the EndoLIF cage promoted by Joimax in Germany has no expansion function and is easy to exit
