颈椎MED(Micro Endoscopic Posterior Cervical Discectomy)

显微内窥镜下行颈椎间盘摘除术,一般从颈后部进行。穿刺针定位,在皮肤上作1.8cm大小切口,逐级扩张,在椎板外放置工作通道,带光源的摄像头及其它手术器械经由此通道进入手术部位,术者将椎板及小关节内缘切出小的骨洞,即可显露椎管内的脊髓和神经根。将神经根轻柔地牵开,即可取出突出的椎间盘。

  A cervical herniated disc may be treated by removing part of the disc through a small incision (microdiscectomy). If this is done from the back (posteriorly) rather than from the front of the neck, a spinal fusion is not necessary. The alternative is an anterior cervical discectomy and fusion procedure.

  颈椎间盘疝出可以通过经小切口(显微椎间盘摘除)将部分椎间盘取出来治疗。如果不从颈前路,而是从背侧(后路)进行该手术,就不需要进行脊椎融合。替代方法是从前路行颈椎间盘切除并融合。

Overview(概述)

  This surgery removes bone and/or portions of a herniated or diseased disc torelieve neck and radiating arm pain caused by parts of the disc pressing on nerve roots.

  本手术将骨和/或部分疝出或病变椎间盘去除,以缓解因部分椎间盘压迫神经根引起的颈痛和上肢放射痛。

Guide Wire Inserted(插入导丝)

  Through a small incision, a guide wire is inserted to locate 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.

  通过小切口,插入导丝来确定受累椎间盘节段。外科医生借助特殊类型的称为透视的X线机来确定到达疝出椎间盘的入路在正确位置。

Retractor Positioned(放置牵开器)

  The tubular retractor, through which the surgery will be performed, Slides over the dilating tubes. It is positioned on the bone surface. All the dilation tubes are then remorved.

  沿扩张管道放置通道牵开器,其前端位于骨表面,手术将由此进行。将所有的扩张管取出。

Instuments Inserted(放置设备)

  A surgical light and small camera or microscope placed through the tube to allow the surgeon to view the disc. The surgeon uses surgical instruments to clear away bone and soft tissue, accessing the spinal canal.

  经通道放置外科手术光源和小摄像头或显微镜,便于外科医生观察椎间盘。外科医生使用手术器械将骨和软组织清除,进入椎管。

Nerve Exposed(显露神经)

  A drill may be used to clear away bone, exposing the pinched nerve root and the herniated disc below it.

  医生可能会使用磨钻将骨去除,显露受压的神经根及其深层的疝出的椎间盘。

Nerve Inspected(检查神经)

  A small instrument is passed through the retractor tube and used to check the freedom of the nerve.

  经牵开通道使用小器械检查神经的自由度。

Damaged Disc Removed(去除受损椎间盘)

  Then surgeon removes the herniated potion te disc and clears the area. Creating room for the nerve to move back to its normal position.

  然后,外科医生将疝出部分的椎间盘去除,并清理局部,为神经留出空间以便它回到正常位置。

End of Procedure(手术结束)

  The tubular retractor is removed, allowing the tissue to close. The surface wound is covered with a samll bandage.

  取出通道牵开器,使组织闭合,表面伤口用小敷料包扎。
