Abstract

Pour répondre à la nécessite d'exercer des forces de compression externes sur la structure interne d'êtres vivants, on fait appel à différents dispositifs médicaux et procédés. La présente invention concerne un dispositif médical (100) prévu pour venir en appui contre la surface du corps d'un être vivant et pour exercer une force sur le bassin de l'être vivant, en particulier pour comprimer la symphyse pubienne et/ou l'articulation sacro-iliaque, comprenant : un mécanisme de réglage de taille (20) pour ajuster le diamètre du dispositif médical actif autour du bassin ; un mécanisme de compression (20a) pour appliquer une/la force prédéfinissable au bassin de l'être vivant, en particulier avec un mécanisme à câble de traction à palan ; une partie de fixation (30) prévue pour régler de manière réversible la taille sélectionnée du diamètre actif ; et une partie de tolérance au mouvement (40) prévue pour un agencement tolérant le mouvement, des parties longitudinales (18) du dispositif médical les unes par rapport aux autres. Selon l'invention, de tels dispositifs peuvent être optimisés par l'emploi de moyens de fixation qui permettent d'améliorer le mécanisme de réglage de taille et d'optimiser l'adaptation au mouvement. De ce fait, la gamme d'applications est également élargie.
