Abstract

La présente invention concerne une aiguille de suture (45) chirurgicale constituée d'une tige de forme allongée se définissant par une première extrémité s'affinant en une pointe, par une seconde extrémité et par une partie médiane. Dans la partie médiane se trouve une rainure (46) axialement alignée menant à un trou aveugle dans lequel une suture (48) chirurgicale est retenue de façon fixe. L'invention concerne également un porte-aiguille (10) constitué d'un tube (31) de forme allongé comportant une cavité interne et une face distale (35) arrondie. Une rainure externe (36) présente une profondeur suffisante pour y retenir une suture. Le porte-aiguille de suture comporte également, au voisinage de l'extrémité distale, une paire d'ailettes (37), chaque ailette étant fixée en l'une de ses extrémités au tube par un pivot, l'autre extrémité de chaque ailette étant pourvue d'un dispositif de fixation d'aiguille (38). Pour commander le mouvement de pivotement des ailettes, le porte-aiguille de suture comporte en outre un organe de commande (32) raccordé à la paire d'ailettes.
