Abstract

L'invention concerne un sachet protecteur médical destiné à recueillir des particules de tissu séparées d'un tissu réséqué lors d'un morcellement, le sachet protecteur pouvant être gonflé au moyen d'un gaz et, une fois gonflé, comportant un espace de réception rempli de gaz pour le tissu réséqué. Le sachet protecteur comprend une première ouverture permettant d'introduire le tissu réséqué dans l'espace de réception du sachet protecteur et au moins un col formé par un tuyau flexible, débouchant dans l'espace de réception et présentant une deuxième ouverture. Le sachet protecteur présente un état de départ, dans lequel une première partie de l'étendue longitudinale du tuyau flexible est retournée et entoure une deuxième partie de l'étendue longitudinale du tuyau flexible. Le col est à double paroi au moins une sur partie de sa longueur et peut être déployé pour augmenter sa longueur.
