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.

The present application relates to lumbar abnormal image recognition method and system, wherein the lumbar abnormal image recognition method comprises the following steps: acquiring the lumbar region MRI image, positioning the left and right apices of the intervertebral disc and the posterior apices of the spinal canal as key points; determining the region of interest in the lumbar image according to the positioned key points, and obtaining the shape image of the lumbar spinal canal through pretreatment; inputting the obtained lumbar spinal canal shape image into the trained classification network model, and judging whether the image contains the abnormal shape of lumbar spinal canal stenosis. By positioning the key points, the region of the lumbar spinal canal is roughly determined, and the most interesting lumbar center region in machine learning is sent into the classification network. Compared with the existing technology of sending the whole MRI image into the classification neural network, the irrelevant information in the network input can be reduced, the features related to the spinal canal stenosis can be more focused on, the abnormal shape image of the lumbar spinal canal stenosis existing in the image data can be accurately recognized, and the recognition accuracy is improved.

The present disclosure is directed to devices, kits, and methods for treating lumbar spinal stenosis by at least partially decompressing a compressed nerve root. The method can include identifying the compressed nerve root and percutaneously accessing a region of a lamina located adjacent to the compressed nerve root. The method can also include forming a channel through the region of the lamina, wherein the channel can be formed medial to a lateral border of the lamina. Further, the method can include expanding the channel in a lateral direction.

A method and system for detecting spinal stenosis is provided. The method may receive image data corresponding to a spine region of a patient. The method may also identify a spinal cord in the image data. The method may determine at least one compression of the spinal cord and may mark an anatomical element proximate to a location of the determined at least one compression to yield at least one marking. The method may generate a decompression plan based on the at least one marking.

The invention discloses a spinal stenosis minimally invasive nerve protection decompression device, and relates to the related field of spinal stenosis minimally invasive, the spinal stenosis minimally invasive nerve protection decompression device comprises a fixing cylinder, the outer side of the upper end of the fixing cylinder is fixedly provided with a connecting block, and the lower end of the circle center of the fixing cylinder is movably provided with a fixing long needle; the top of the fixed long needle is fixed to the bottom end of the rotating ball body, a locking mechanism is arranged at the bottom of the threaded pipe, and the locking mechanism acts between the rotating ball body and the fixed ball body to achieve relative locking of the rotating ball body and the fixed ball body. According to the spinal canal stenosis minimally invasive nerve protection decompression equipment, a second rotating block drives a threaded pipe to move downwards, an arc-shaped ball is driven to extrude two sets of symmetrical locking blocks, the position of a drag hook can be accurately controlled, and the complexity and injury risk of manual nerve traction are avoided; through the cooperation of the penetrating type cleaning pipe and the one-way nozzle, the operation area can be cleaned synchronously, the pollution hidden danger in the operation is reduced, and the multiple requirements for nerve protection, operation efficiency and operation precision in the minimally invasive scene are met on the whole.

A system and method for excising tissue from a stenotic spinal region is disclosed. The system may comprise a surgical kit including an access instrument, a bone reamer, a bone removal instrument, and a soft tissue removal instrument. The access device may be cannulated and utilized to achieve a path for the insertion and advancement of the other surgical instruments towards a target area, such as the interlaminar region. The bone removal and / or soft tissue removal instrument may be used at various angular orientations and depths within the lumbar region to ergonomically excise compressive features including hypertrophied ligamentum flavum. Minimally invasive and open procedures are disclosed.

Catheter system, devices and methods for diagnosing and treating lateral stenosis causing back pain and or leg pain. The devices comprise a tubular part for insertion into a working cannula to self-position itself safely within the foramen, and minimize the risk of displacement medially or laterally, to prevent nerve or dura injury. An expandable membrane is configured to maintain the catheter device within the foramen. Expansion of this membrane would decompress the nerve within the foramen by opening the foraminal canal as the membrane expands.

The invention discloses a traditional Chinese medicine composition for treating lumbar spinal stenosis and a preoperative and postoperative conditioning method thereof, and belongs to the technical field of traditional Chinese medicines. Aiming at the problem of lack of relatively stable intervention measures before and after an operation, a traditional Chinese medicine component distribution strategy is divided into two parts, namely preoperative components and postoperative components, the preoperative components comprise astragalus membranaceus, codonopsis pilosula, loranthus parasiticus and the like which are used for benefiting qi and nourishing blood; the postoperative components comprise ground beetles, deer-horn glue, pseudo-ginseng powder and the like which are used for promoting blood circulation to remove blood stasis. Preoperative and postoperative operations are fully considered, and a whole-stage recovery curative effect is provided for a patient. Meanwhile, the traditional Chinese medicine components are forbidden by pregnant women, so that the medication safety is ensured. According to the research experience of lumbar spinal stenosis at the present stage, adaptation is performed according to the corresponding age stage, and in the young stage, muscle and bone strengthening drugs such as radix achyranthis bidentatae are added; at the middle-aged stage, liver and kidney tonifying medicines such as radix rehmanniae preparata are added; in the old stage, dogwood and other medicines for consolidating basis are added, so that adaptation of all ages is realized.
