Oval dilator and retractor set and method |
摘要 |
Access to a greater area of surgical site with minimally invasive procedure is obtained by using two sets of sequentially placed tissue dilators oriented with their axes in a plane parallel to the spinal axis and a final non-circular dilator encompassing the two sets, followed by a non-circular tubular retractor providing a working channel extending longitudinally of the spine.
