    • An apparatus for tissue separation comprises a hollow retractor expandable in at least one dimension, the retractor having upper and lower guide surface portions for contacting respective upper and lower tissue surfaces; a first dilator having a distal portion configured to fit inside the upper and lower guide surface portions of the retractor so as to expand a distance between the upper and lower guide surface portions of the retractor and thereby separate the upper and lower tissue surfaces by a first distance; and a second dilator having a distal portion configured to fit inside the upper and lower guide surface portions of the retractor so as to expand a distance between the upper and lower guide surface portions of the retractor and thereby render the upper and lower tissue surfaces being separated by a second distance, the second distance greater than the first distance.
    • 用于组织分离的装置包括可在至少一个尺寸上扩张的中空牵开器,所述牵开器具有用于接触相应的上部和下部组织表面的上部和下部引导表面部分; 第一扩张器,其具有构造成装配在牵开器的上部和下部引导表面部分内的远端部分,以便扩张牵开器的上部和下部引导表面部分之间的距离,从而将上部和下部组织表面分开第一 距离; 以及第二扩张器,其具有构造成配合在所述牵开器的上部和下部引导表面部分内侧的远侧部分,以便扩张牵开器的上部和下部引导表面部分之间的距离,从而使上部和下部组织表面分离 第二距离,第二距离大于第一距离。
