  • Method and system for performing endoscopic surgery at locations where tissue inserts into bone
    Patent number: 5429117
    Abstract: An endoscopic system and method for performing endoscopic surgery at locations where tissue inserts into bone which includes a sleeve member, obturator, cutting and excision instruments, and a marking and insertion assembly wherein the sleeve member has an expanded portal through which instrument access and improved visualization can be performed at arcuate lines of insertion of tissue into bone. The sleeve member can include a flange for engaging tissue along the line of insertion and exposing the bone and measurement means for gauging precisely the reduction or resection of bone. An alternative embodiment of the sleeve member has a non-uniform aperture with an instrument portion and a register portion providing increased space and maneuverability for instruments when operating at the portal on tissue or bone that can include the flange. Cutting instruments are provided with an extension portion to extravasate from tissue and palpitate underlying tissue.
