VERTEBRALLY-MOUNTED TISSUE RETRACTOR AND METHOD FOR USE IN SPINAL SURGERY
First Claim
1. A retractor system for a surgical site on a spine comprising a retractor, the retractor being a hollow structure comprising:
- a proximal surface having a proximal aperture,a base comprising a distal aperture, the base configured to couple to one or more vertebral bodies, the distal aperture smaller than the proximal aperture; and
an internal surface connecting the proximal aperture and the distal aperture, the surface and the apertures defining a distally-narrowing operating volume.

Abstract
A retractor system and associated method are provided to manage soft tissue around a spinal surgical field. The system includes a hollow retractor with proximal and a distal apertures and an internal circumferential surface connecting the apertures, the surface and the apertures defining an operating volume and the area of the distal aperture defining an operating field. The system may further include other elements such as a handling tool to facilitate placement and removal of the retractor, a bone cutting tool, a trajectory control sleeve to guide the bone cutting tool, and/or an implantable bone plate upon which to position the retractor. A method for spinal surgery, particular from an anterior approach, includes positioning the retractor at a surgical site, and performing a medical procedure through the operating volume provided by the retractor.

22. A method for performing a medical procedure on a spine from an anterior approach comprising:
-
positioning a retractor at a surgical site on the spine such that the retractor contacts one or more vertebral bodies and maintains retraction of soft tissue surrounding the site, the retractor being a hollow structure comprising a proximal surface having a proximal aperture, a base comprising a distal aperture, the base configured to couple to one or more vertebral bodies, the distal aperture smaller than the proximal aperture; and
an internal surface connecting the proximal aperture and the distal aperture, the surface and the apertures defining a distally-narrowing operating volume; andperforming the medical procedure through the operating volume of the retractor. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
