Abstract

L'invention concerne une matière de renforcement des ligaments, dans laquelle trois composantes, des portions annulaires, linéaires et ramifiées (des portions linéaires et une portion annulaire), sont chacune tressées au moyen d'un élément de production de tresse ou reliées aux portions linéaires au moyen d'un métal mou, ou un feuille est utilisée afin de fixer l'extrémité de façon plus élaborée, cette matière renforce donc ainsi le tissu de la personne. Cette matière est simple et pratique et fournit des résultats constants. Elle possède une élasticité d'étirement correspondant au tissu humain, permet la fixation d'une extrémité sectionnée à un endroit facultatif, et réduit le volume de matière de fixation à introduire dans le corps humain. Le montage d'une plaque d'extrémité, d'une vis d'extrémité ou d'un bouchon d'extrémité dans la matière de renforcement des ligaments réduit le nombre d'heures d'opération, les plaies résiduelles, ainsi que le volume du tunnel osseux. L'invention concerne également une matière de renforcement du corps humain sur laquelle on a fixé un corps rotatif afin de protéger les tissus de la personne des dommages.
