Abstract

L'invention concerne un dispositif de traction pour intervention chirurgicale et, plus particulièrement, un dispositif de traction qui agrandit une partie incisée de la peau pour faciliter l'insertion d'un instrument chirurgical, et comprend un module d'extension résiliente de forme cylindrique qui retient la partie incisée au sommet d'un module de fixation de sorte que la partie incisée soit maintenue dans un état agrandi. Selon l'invention, le module d'extension, constitué d'un matériau résilient, s'insère dans une partie incisée de manière à pouvoir former un espace pour l'intervention chirurgicale. Et comme le module d'extension peut être facilement couplé à ou séparé d'un module de fixation, un effet est créé qui, pendant une intervention chirurgicale, facilite un changement de position du dispositif de traction ou son retrait.
