| 简介 |
A percutaneous and minimally inva-sive instrument for inserting an interspinous process spacer into a patient is disclosed. The instrument in-cludes a first assembly connected to a handle assem-bly.
The first assembly includes an inner shaft located inside an outer shaft and configured for translational motion with respect to the outer shaft. The relative translational motion causes one of the outer or inner shafts to move with respect to the other and thereby deflect at least one prong formed on one of the inner or outer shafts wherein such deflection causes engage-ment with a juxtapositioned interspinous spacer. The instrument further includes a driver configured for re-movable insertion into a proximal end of a passage-way of the instrument. The driver has a distal spacer engaging portion configured to engage that part of the spacer requiring activation for deployment of the spacer from an undeployed configuration to a de-ployed configuration and vice versa. |
