The system and method in order to remedy the rachis tube stenosis include the endoscope access device and the bone removal device which are used for between hole enlargement technique or the execution of other bone removal operation. The bone removal device includes the cannula insertion type incision sword which possesses the image pickup lumen for the endoscope. To option, can the endoscope retention device, use in order to make the advance of the endoscope easy through the cannula insertion type incision sword. Being explained to this bill has the organizational removal device which has the proximal handle and the periphery which possesses the taper condition salient, in order long and narrow to receive the shaft and the endoscope which possesses the lumen which the terminal is done in the distal (2036) open part, long and narrow it is the system for the vertebral operation which is possible to have with the endoscope retention device which has support which is formed structure.脊柱管狭窄症を治療するためのシステムおよび方法は、椎間孔拡大術または他の骨除去手術の実行に使用する内視鏡的アクセスデバイスおよび骨除去デバイスを含む。骨除去デバイスは、内視鏡用撮像内腔を有するカニューレ挿入型切開刀を含む。随意に、内視鏡保持デバイスは、カニューレ挿入型切開刀を通して、内視鏡の前進を容易にするために使用することができる。本明細書に説明されるのは、近位ハンドルを備える組織除去デバイスと、テーパ状突出部を有する周辺部を備える、遠位開口部で終端する内腔を有する細長シャフトと、内視鏡を受容するように構成される細長支持構造を備える内視鏡保持デバイスとを備えてもよい脊椎手術のためのシステムである。
