The Observation of the Spinal Canal and its Contents Using Newly Developed Ultrathin Fiber Optic Myeloscope.

新研制的超薄纤维脊髓镜对人椎管及其内容物的观察本研究的目的是用纤维超薄脊髓镜直接观察脊髓、马尾神经的部分神经或血液成分以及硬膜外间隙。我们的脊髓纤维镜已成功地显示了98例成人的马尾神经至枕大池的脊髓。外径0.75 mm、工作长度120 cm的插管非常灵活。该仪器有4000夸兹光纤像导和35个光导。在局麻下用18G Tuohy针悬吊法确定腰椎蛛网膜下腔。可见大量脊神经根及其伴行血管、脊髓肿瘤、粘连性蛛网膜炎。这一过程将有助于建立肿瘤、椎管狭窄或神经血管压迫的鉴别诊断。

The observation of the human spinal canal and its contents using newly developed ultrathin fiberoptic myeloscope. The purpose of this study was observed directly the spinal cord, some of the nerves or blood constituents of cauda equina and epidural space with fiberoptic ultrathin myeloscope.Our myelofiberscope has been used successfully in visualizing the spinal cord from cauda equina to cisterna magna in 98 adults. It is very flexible with insertion tube of outer diameter 0.75mm and with a working length of 120cm. This instruments has 4000 quartzfiber optic image guide and 35 light guides. The lumbar subarachnoid space was identified by the hanging drop method with an 18 Gauge Tuohy needle under local anesthesia. We could see the many spinal nerve roots with its accompanying blood vessels, spinal cord tumor, adhesive arachnoiditis. This procedure would be useful for establishing the differential diagnosis of tumor, spinal canal stenosis or neurovascular compression.
