The present invention relates to surgical retractors and devices for stabilizing a predetermined area of the body during a surgical procedure, more particularly to surgical retractors and stabilizing devices used in connection with minimally invasive coronary artery bypass grafting surgical procedures, and more specifically to surgical retractors and stabilizing devices especially configured for use with each other for such surgical procedures wherein the retractor includes an external rail system which enables the surgeon to position a stabilization arm on either of the arms or the rack segment of the retractor and also includes a connector which releasably controls the rotation of the connector with respect to the retractor and the rotation of the stabilization arm with respect to the retractor as well as the rotational and sliding movement of the stabilization arm with respect to the connector upon actuation of a single knob or actuator.

La présente invention concerne des écarteurs chirurgicaux et des dispositifs destinés à stabiliser une zone prédéterminée du corps lors d'une intervention chirurgicale, en particulier des écarteurs et des dispositifs stabilisants utilisés en relation avec des procédures chirurgicales de greffe de dérivation d'artère coronaire avec invasion minimale. L'invention concerne plus spécialement des écarteurs et des dispositifs stabilisants spécialement configurés afin d'être utilisés ensemble lors d'interventions chirurgicales dans lesquelles l'écarteur comprend un système de rail externe qui permet au chirurgien de positionner un bras de stabilisation sur l'un des bras de segment de crémaillère de l'écarteur. Cet écarteur comprend aussi un connecteur qui permet de commander, de manière détachable, la rotation du connecteur par rapport à l'écarteur, la rotation du bras de stabilisation par rapport à l'écarteur, aussi bien qu'un mouvement de rotation et de glissement du bras de stabilisation par rapport à l'écarteur lors de la mise en oeuvre d'un bouton unique ou d'un actionneur.
