METHOD AND APPARATUS FOR MINIMALLY INVASIVE INSERTION OF INTERVERTEBRAL IMPLANTS |
摘要 |
METHOD AND APPARATUS FOR MINIMALLY INVASIVE INSERTION OF INTERVERTEBRAL IMPLANTS A dilation introducer for orthopedic surgery is provided for minimally invasive access for insertion of an intervertebral implant. The dilation introducer may be used to provide an access position through Kambin's triangle from a posterolateral approach. A first dilator tube with a first longitudinal axis is provided. A second dilator tube may be introduced over the first, advanced along a second longitudinal axis parallel to but offset from the first. A third dilator tube may be introduced over the second, advanced along a third longitudinal axis parallel to but offset from both the first and the second. An access cannula may be introduced over the third dilator tube. With the first, second, and third dilator tubes removed, surgical instruments may pass through the access cannula to operate on an intervertebral disc and/or insert an intervertebral implant.
