Embodiments of surgical access cannulas and access systems for use in gaining access to a body cavity of a patient via a natural orifice are disclosed. A distal end of an access cannula is advanced through a natural orifice into a hollow organ. Instruments passed through the cannula are used to form an incision in the wall of the hollow organ. The access cannula is anchored in the incision with its distal opening giving access to a body cavity outside the hollow organ. Surgical instruments are passed through the access cannula and used to perform procedures in the body cavity.

L'invention porte sur des canules et des systèmes d'accès chirurgicaux utiles pour pouvoir accéder à une cavité du corps d'un patient par un orifice naturel. Pour cela, on fait avancer une extrémité distale d'une canule d'accès par un orifice naturel d'un organe creux. Les instruments qui passent par la canule sont utilisés pour pratiquer une incision dans la paroi de l'organe creux. La canule d'accès est ancrée dans l'incision par son orifice distal donnant accès à une cavité du corps à l'extérieur de l'organe creux. On fait passer les instruments chirurgicaux par la canule d'accès et on les utilise pour effectuer des interventions dans une cavité du corps.
