A lumbar micro endoscopic discectomy is a minimally invasive procedure performed through a tubular device and designed to relieve pain caused by herniated discs pressing on nerve roots. This video provides an overview of the lumbar micro endoscopic discectomy.
显微内窥镜下腰椎间盘摘除术是通过管道系统做的微创手术，用于缓解因椎间盘突出压迫神经而引起的疼痛。本视频简要介绍显微内窥镜下腰椎间盘摘除术的方法。
Overview （概述）
This minimally-invasive proceduree is performed through a tubular device. It is designed to relieve pain caused by herniated discs pressing on nerve roots. This surgery is usually performed on and outpatient basis, which allows the patient to leave the hospital the same day.
这个微创手术通过一个管道系统来实施。它被设计用于缓解因椎间盘突出压迫神经而引起的疼痛。这个手术通常可以在门诊基地进行，也就是病人在手术当天可以出院。
Guide Wire Inserted（插入导丝）
A guide wire is insertedd through a small incision and is pushed to the affected disc level. The surgeon uses a special type of X-ray machine called a fluoroscope to ensure that the route to the herniated disc is made in the correct location.
通过一个小切口，将导丝插入，到达病变椎间盘水平。术者使用特殊的称为透视的X线机确定通往突出椎间盘的路径在正确的位置。
Dilating Tubes Inserte（插入扩张管道）
A series of dilating tubes are passed over the guide wire to push apart the tissue down to the vertebrae. The guide wire is then removed.
在导丝的引导下逐级插入一系列的扩张管道，将椎体表面的软组织推开，然后将导丝去除。
Retractor Inserted（插入工作通道）
The tubular retractor, through which the surgery will be performed, is slid over the dilating tubes. It is positioned on the bone surface. All the dilating tubes are the removed.
沿扩张管将管道式牵开器插入，到达椎骨表面，手术经此通道实施。然后将所有的扩张管道取出。
Instruments inserted（插入相关设备）
A surgical light and small camera or microscope are used to see through the tube. Surgical instruments are used to clear away bone and soft tissue in order to access the spinal canal.
通过管道使用手术照明灯及小型摄像头或显微镜来显露术野。用外科器械来清除骨和软组织以便进入椎管。
Spinal Nerve Moved（推开脊神经）
The surgeon uses a nerve retractor to gentely move the nerve away from the herniated disc.
术者使用神经牵开器轻柔地将神经从突出椎间盘上牵开。
Herniated Portion Cleared（清除突出椎间盘）
The herniated portion of the disc is removed and the area is cleared, which allows room for the nerve to move back to its normal position.
去除椎间盘的突出部分，清理局部，便于神经根回复到正常位置并有充足的空间。
End of Procedure（手术结束）
The tubular retractor is removed, allowing the body tissue to close around the surgery area. The surface wound is closed with a small bandage.
将管道式牵开器去除，人体组织关闭手术部位。表面的伤口用一个小敷料覆盖包扎。
