Abstract
Description
図34に、上端部166と下端部168を持つ非軸対称膨張装具153を示す。膨張装具153は、バリヤー12のフレームを形成する。本実施形態は、切開表面か端部160、放射状要素かフィンガー162及び中心支柱164からなる。切開端部160の円形により、髄核20及び/又は線維輪10内面に沿うか、又はその間を切開する手助けとなる。切開端部の最も左よりの点と最も右よりの点間の距離が膨張手段長さ170となる。この長さ170は、好ましくは移植後、後方輪の内周に位置する。膨張装具長さ170は、最短で約3mm、最長で線維輪の全内周でも良い。この切開端部160の上下高さは、好ましくは、後方椎間板の高さと等しいかそれより高い。
図80Aから図80Dに本発明のある実施形態による突起部612の種々の断面を示す。
当業者は、核増強物及び/又は輪増強物を含む上記手順のいずれかを自己の核のいずれか又は全てを除去する、除去しなくても実行できることが分かる。更に、核増強部材及び/又は輪増強装具がもはや必要で無くなったときに、安全且つ効果的に取り除けるように構成することができる。
