A laparoscopic surgical retractor (100) for use during a laparoscopic spinal procedure includes an elongated sleeve member (102) having proximal and distal end portions, defining a longitudinal opening therethrough, and a valve assembly (200) mounted to the proximal end portion of the elongated sleeve member for seating a surgical instrument introduced within the longitudinal opening of the sleeve member. The distal end portion is configured for insertion at least partially into an intervertebral space between adjacent opposed vertebrae to distract the adjacent vertebrae. A method for inserting a fusion implant (700) with the use of the retractor is also disclosed.

Cet écarteur inclut un manchon allongé (102) présentant une extrémité proximale et une extrémité distale qui délimitent une ouverture longitudinale. Le manchon allongé présente en outre un ensemble soupape monté sur son extrémité proximale pour fermer hermétiquement un instrument chirurgical inséré dans l'ouverture longitudinale du manchon. L'extrémité distale est configurée de manière à s'insérer au moins partiellement dans un espace intervertébral entre deux vertèbres adjacentes opposées et les écarter. L'invention porte également sur un procédé utilisant ledit écarteur pour insérer un implant de fusion (700).
