Abstract

L'invention concerne un instrument chirurgical à effraction minimale pour greffon cartilagineux à ingénierie tissulaire comprenant une pince (1) dotée de deux pointes de pince (2) en pointes incurvées. La pointe de pince (21) disposée sur un côté supérieur est pourvue de trous traversants (5) répartis uniformément sur une surface de la pointe de pince (21), les trous traversants (5) traversant deux surfaces latérales d'un côté supérieur et d'un côté inférieur de la pointe de pince (21), et une première partie barrière (8) est présente entre deux trous traversants adjacents (5) ; la pointe de pince (22) disposée sur un côté inférieur est dotée d'évidements (6) sur une paroi périphérique externe, et les évidements (6) sont disposés à intervalle le long de la paroi périphérique externe, et ont des emplacements correspondant aux emplacements des trous traversants (5), une seconde partie barrière (7) se situant entre deux évidements adjacents (6), et une structure en forme de dent rectangulaire est formée entre l'évidement (6) et la seconde partie barrière (7). Le support possédant deux pointes de pince incurvées (2) munies de trous et de dents respectivement forme des trous de suture après fermeture, répondant ainsi au problème de maintien en place d'une membrane de collagène pendant la suture arthroscopique.
