Spine surgery device, affiliated guide sleeve, and set with guide sleeve

摘要

The intervertebral disc between them is damaged, so that it can load the patient during percutaneous spinal surgery to introduce an intervertebral cage (an interbody cage) between the two vertebrae from which it has been removed. In order to reduce as much as possible, the present invention first proposes a guide sleeve (3) for spinal surgery having a non-cylindrical mantle (3.1). In order to solve the above-mentioned problems of the present invention, a spinal surgery set comprising at least one guide sleeve of the above type and a dilator (4) is proposed, the outer contour of the dilator being the lumen of the guide sleeve. It is adapted to the contour. Finally, the present invention proposes a spinal surgical set consisting of a guide sleeve and an intervertebral cage to be introduced by this guide sleeve, in which the guide sleeve lumen is adapted to the maximum cross-sectional profile of the intervertebral cage. ing.
