An apparatus and method for minimally invasive suturing is disclosed. A suturing device for minimally invasive suturing includes proximal section having a proximal end, a distal end, and a longitudinal axis therebetween; a suture head assembly extending from the distal end of the proximal section; a suturing needle having a pointed end and a blunt end, the suturing needle capable of rotating about an axis approximately perpendicular to a longitudinal axis of the proximal section, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to and after rotation of the suturing needle; and an actuator extending from the proximal end of the proximal section to actuate a drive mechanism having a needle driver for engaging and rotating the suturing needle.

L'invention concerne un appareil et procédé pour une suture à invasion minimale. Un dispositif de suture pour une suture à invasion minimale comprend une section proximale comportant une extrémité proximale, une extrémité distale et un axe longitudinal entre les deux; un ensemble tête de suture s'étendant depuis l'extrémité distale de la section proximale; une aiguille de suture comportant une extrémité pointue et une extrémité épointée, l'aiguille de suture pouvant tourner autour d'un axe à peu près perpendiculaire à l'axe longitudinal de la section proximale, dans lequel l'extrémité pointue de l'aiguille de suture est placée dans l'ensemble tête de suture avant et après la rotation de l'aiguille de suture; et un actionneur s'étendant depuis l'extrémité proximale de la section proximale pour actionner un mécanisme d'entraînement comportant un pilote d'aiguille pour enclencher et faire tourner l'aiguille de suture.
