A suture fastening device for forming a welded suture joint in situ includes a horn (8), and an anvil (16) movable relative to each other in a tubular shaft (3), a source of power (6) for actuating he horn, and anvil within the shaft, and relative to each other. Segments (20a, 20b) of a suture to be joined are captured within the anvil, and contacted by the horn for transfer of energy thereto during welding. A predetermined condition of the welded joint or of the horn, and anvil is detected so as to control the delivery of energy to the segments during welding.
L'invention concerne un dispositif d'attache de fils de suture permettant de former in situ un joint de suture soudé. Ce dispositif comporte un bras de soudure (8) et un contre-outil (16) mobiles l'un par rapport à l'autre dans une tige tubulaire (3), et un source d'alimentation (6) permettant d'actionner le bras, le contre-outil à l'intérieur de la tige, et les deux l'un par rapport à l'autre. Des segments (20a, 20b) d'un fil de suture à joindre sont enserrés à l'intérieur du contre-outil, le bras entrant en contact avec ceux-ci afin d'y transférer de l'énergie durant le soudage. On détecte une condition prédéterminée du joint soudé ou du bras et du contre-outil, de manière à commander l'apport d'énergie aux segments lors du soudage.
