A needle passer instrument for use in minimally invasive surgical procedures, including arthroscopy. The instrument has upper and lower jaws for engaging tissue and a handle. A removable needle engaging cartridge is mounted to the upper jaw. A surgical needle with attached suture is mounted in a needle passage in the lower jaw. A needle actuation rod engages the surgical needle and pushes the needle through tissue contained between the jaws. The needle is engaged by the cartridge, and the needle may be cut away from the suture.

Il s'agit d'un instrument à passage d'aiguille pour actes chirurgicaux à effraction minimale, y compris l'arthroscopie. Cet instrument est muni de mâchoires supérieure et inférieure qui permettent d'accoupler des tissus et une poignée. Une cartouche engageant une aiguille amovible est montée sur la mâchoire supérieure. Une aiguille chirurgicale avec fil de suture est placée dans le passage de l'aiguille de la mâchoire inférieure. Une tige de manoeuvre d'aiguille s'accouple à l'aiguille chirurgicale et la pousse à travers les tissus pris entre les mâchoires. L'aiguille est accouplée par la cartouche, et l'aiguille peut être enlevée de la suture.
