Title (EN) SURGICAL INSTRUMENTS
(FR) INSTRUMENT CHIRURGICAL
Abstract:
(EN) The invention relates to instruments for surgery, particularly endoscopic surgery. In a first aspect the invention provides an instrument for placing sutures comprising an elongate shaft (20) terminating in a head (30) with a needle (31) having a tip (37), wherein said needle (31) has means (36) for releasable retaining suturing material and wherein said head (30) is profiled so that axial rotation of the shaft (20) moves the tip (37) forwardly of the instrument to draw suturing material forwardly and through tissue. In a second aspect the invention provides an instrument for pushing and retrieving ligatures comprising an elongate shaft (70) terminating in a head (80) with a suture material engaging portion (85), said engaging portion (85) comprising first and second opposed curved surfaces (87a, 87b) wherein the first curved surface (87b) is adapted to allow the suture material to be pushed toward a patient and the second curved surface (87a) is adapted to allow the suture material to be pulled away from a patient.
(FR) L'invention concerne des instruments pour chirurgie, en particulier pour la chirurgie endoscopique. Selon un premier aspect, l'invention concerne un instrument pour placer des sutures, comprenant un arbre allongé (20) se terminant par une tête (30) avec une aiguille (31) ayant une extrémité (37), où ladite aiguille (31) a un moyen (36) pour retenir d'une manière réversible du fil pour suture et où ladite tête (30) est profilée de manière à ce que la rotation axiale de l'arbre (20) déplace l'extrémité (37) vers l'avant de l'instrument pour tirer le fil pour suture vers l'avant et à travers le tissu. Selon un second aspect, l'invention concerne un instrument pour pousser et extraire des ligatures comprenant un arbre allongé (70) se terminant par une tête (80) avec une portion (85) s'engageant avec le fil de suture, ladite portion d'engagement (85) comprenant des première et seconde surfaces courbes opposées (87a, 87b), où ladite première surface courbe (87b) permet au fil de suture d'être poussé dans la direction du patient et la seconde surface courbe (87a) permet d'extraire le fil de suture du patient.
