Title
(EN) SPINAL ACCESS SYSTEM AND METHOD
(FR) SYSTÈME ET MÉTHODE D'ACCÈS À LA COLONNE VERTÉBRALE
Abstract
(EN)
Described herein are devices and systems for accessing a spine and particularly the epidural region of the spine and methods of using these systems and devices to access the spine or regions of the spine. In particular, cannulas that may be anchored to the ligamentum flavum or the periosteum are described. Ligamentum flavum access tools are also described. These tools may be used with (or without) an anchoring cannula to penetrate the ligamentum flavum and provide access to the epidural space without risk of injury to other structures within the epidural space. The devices, methods and systems described herein are particularly useful in minimally invasive surgical (MIS) uses. The devices, methods and systems described herein may be used for performing spinal decompressions and other spinal procedures.
(FR)
La présente invention concerne des dispositifs et des systèmes permettant d'accéder à une colonne vertébrale et, plus particulièrement, la région épidurale de la colonne vertébrale, ainsi que des procédés d'utilisation de ces systèmes et dispositifs permettant d'accéder à la colonne vertébrale ou des régions de la colonne. L'invention porte notamment sur les canules qui peuvent être ancrées au ligament jaune ou au périoste. De plus, l'invention a trait aux outils permettant d'accéder au ligament jaune. Ces outils peuvent être utilisés avec (ou sans) une canule d'ancrage afin de pénétrer dans le ligament jaune et permettre d'accéder à l'espace épidural sans blesser les autres structures présentes dans cet espace. Les dispositifs, procédés et systèmes de la présente invention se révèlent particulièrement utiles lors d'interventions chirurgicales à invasivité minimale (MIS). Les dispositifs, procédés et systèmes de la présente invention peuvent être utilisés pour effectuer des décompressions spinales et d'autres procédures.
