经皮经椎间孔内窥镜椎间盘切除术减压后纤维环破裂的缝合技术
2024年1月26日
该方案描述了一种创新的缝合技术，用于在经皮经椎间孔内窥镜椎间盘切除术中破裂的环状纤维。
本研究描述了一种创新的缝合技术，用于经皮经椎间孔内窥镜椎间盘切除术中环状纤维破裂，我们提出了一种通过拉起腰椎下后纵韧带进行内窥镜检查来缝合环状纤维撕裂的方法。要进行腰椎疝症的内窥镜手术技术，外科医生必须具备丰富的经验。然而，并非每个腰椎疝患者都适合采用这种技术。
在某些情况下，如果环状撕裂在减压后变得太窄，则可能不需要缝合。该技术提供了一种新的解决方案，可以解决由于传统的单碟缝合方法在腰椎内窥镜减压后出现的张力不足的问题。此外，环状纤维化撕裂周围的后纵韧带紧密可见，这有助于增加受压段处的腰椎管体积。

Executive Industry Relevance
Innovative suture techniques for annulus fibrosus repair following percutaneous transforaminal endoscopic discectomy address a critical challenge in minimizing recurrence risk after lumbar disc herniation surgery. By leveraging the posterior longitudinal ligament for enhanced closure tension, this method supports more reliable post-surgical outcomes and informs the development of advanced spinal repair strategies. The approach is relevant for R&D teams focused on improving procedural reproducibility and reducing biological failure points in minimally invasive spinal interventions.
