CA 2481180

Methods and devices for performing percutaneous surgery in a patient are provided. A retractor includes a working channel formed by a first portion coupled to a second portion. The first and second portions are movable relative to one another from an unexpanded configuration to an expanded configuration to increase the size of the working channel along the length of the working channel while minimizing trauma to skin and tissue.

L'invention concerne des méthodes et des dispositifs permettant d'effectuer des actes chirurgicaux percutanés sur un patient. Un écarteur comprend un canal de travail formé par une première partie couplée à une deuxième partie. Lesdites première et deuxième parties peuvent être déplacées l'une par rapport à l'autre d'une configuration non allongée à une configuration allongée, de sorte à augmenter les dimensions du canal de travail sur sa longueur, tout en réduisant au minimum le traumatisme causé à la peau et au tissu.
