A new p approach full endoscopic lumbar fusion surgery method

PendingCN122272106ALumbar spondylolisthesisIntervertebral space
This invention relates to a novel P-approach endoscopic lumbar fusion surgery method, belonging to the field of lumbar fusion surgery technology. This method addresses the high risk of nerve injury and insufficient operational precision in existing endoscopic fusion techniques by proposing an improved solution. It utilizes Kirschner wires for positioning at the inferior articular process to establish a precise entry point avoiding the nerve root pathway; a visually guided circular saw is used throughout the endoscopic procedure to construct a safe triangular working channel directly reaching the spinal canal; under full endoscopic monitoring, a unilateral approach is used for bilateral spinal canal decompression, thoroughly removing diseased tissue and scraping the endplates until punctate bleeding occurs; a bone graft cannula with a curved tip is used to precisely implant the fusion device into the anterior region of the intervertebral space, restoring intervertebral height through a self-locking structure; finally, a universal pedicle screw is percutaneously implanted for fixation. This method reduces the risk of nerve injury, improves surgical safety and efficiency, and is suitable for patients with lumbar spondylolisthesis complicated by spinal stenosis.

An ergonomic adaptive seat lumbar support method, device and passenger car

This invention provides an ergonomic adaptive lumbar support method, device, and bus, relating to the bus industry. By collecting occupant back pressure distribution data in zones and combining it with a human lumbar spine physiological curvature model to calculate the target inflation volume of each airbag unit, it can automatically identify the body shape characteristics and lumbar support needs of different occupants. Personalized comfort support can be obtained without manual operation by the occupant. Multiple independent airbag units arranged in a matrix achieve multi-zone independent control of the lumbar support, accurately supplementing support in areas with insufficient pressure based on the pressure distribution map, avoiding the lumbar discomfort or unsupported lumbar position problems of traditional single-point lumbar supports. A closed-loop feedback control mechanism is employed to monitor pressure distribution changes in real time during adjustment until a preset comfort range is reached, ensuring high adjustment accuracy and avoiding over-adjustment or under-adjustment.

A biomimetic intervertebral fusion device with a piezoelectric multifunctional coating

A biomimetic intervertebral fusion device with a piezoelectric multifunctional coating belongs to the field of implantable medical devices. It includes an upper piezoelectric multifunctional coating, a fusion device body, and a lower piezoelectric multifunctional coating. A bone graft window is located in the middle of the biomimetic intervertebral fusion device. The piezoelectric multifunctional coating is made of electrospun piezoelectric PVDF / HA fibers, which are conformally adhered to the upper and lower surfaces of the fusion device body through a polydopamine adhesive layer. The upper and lower surfaces of the fusion device body have a biomimetic curved surface configuration to match the morphology of the vertebral endplates, increasing the contact area and reducing stress concentration at the fusion interface. While maintaining an elastic modulus similar to natural bone and good radiation permeability, this fusion device, after implantation, can create a microenvironment conducive to cell adhesion and proliferation. Under the influence of cell traction, ultrasonic stimulation, and the physiological load of the human lumbar spine, it generates electrical stimulation signals, promoting bone fusion, improving the stability of the fusion interface, and reducing the risk of postoperative loosening and subsidence of the fusion device.
