This invention is an access device (10) including an anchoring structure (50) reinforced with an insert (61) and operable by a pair of sutures (65, 67). An electrosurgical obturator (25) is positioned in the tube (10), and functions to place the structure in a low profile state. The obturator (25) can be activated to insert the tube (10) through the abdominal wall (14) and the stomach wall (18) to provide access to the stomach cavity. The sutures (65, 67) can be tensioned to raise the anchoring structure (50) to a high profile state, and draw the stomach into proximity with the abdominal wall. Removing the obturator (25) leaves the tube (10) operatively disposed and providing direct access to the stomach cavity
L'invention concerne un dispositif d'accès (10) comprenant une structure d'ancrage (50) renforcée par une pièce rapportée (61) et fonctionnant au moyen d'une paire de fils de suture (65, 67). Un obturateur électrochirurgical (25) est placé dans le tube (10) et sert à mettre la structure dans un profil bas. On peut mettre en service cet obturateur (25) afin d'introduire le tube (10) à travers la paroi abdominale (14) et la paroi stomacale (18), ce qui permet d'accéder à la cavité stomacale. On peut tendre les fils de suture (65, 67) afin d'élever la structure d'ancrage (50) vers un profil élevé et d'attirer l'estomac à proximité de la paroi abdominale. Lorsqu'on retire l'obturateur (25), le tube (10) reste en place pour l'opération et permet d'accéder directement à la cavité stomacale.
