Embodiment Construction

[0027] The following embodiments of the invention in conjunction with the accompanying drawings, embodiments of the present invention, technical solutions are clearly and completely described.

[0028] The present invention provides a novel tape having high strength and corrosion resistance of magnesium plate loop, embodiments thereof e.g. Figure 1 to 3 , The loop 10 with the surface of the new plate is covered with a magnesium nanocrystal layer 20, the surface of the nanocrystal layer 20 is covered with the pull rope is provided with holes 11 and the holes 10 of the graft ceramic film 30, the new loop with magnesium plate 12, pull rope holes 11 and 12 are through-holes graft new loop with magnesium plate 10, holes 11 for supplying pull rope pull rope through graft holes 12 for allowing through the graft.

[0029] During use, holes 11 for supplying pull rope pull rope through graft holes 12 for allowing through the graft, since the main material of the new plate 10 with loop magne...

Abstract

The invention discloses a novel belt-loop magnesium plate with high strength and corrosion resistance. The surface of the novel belt-loop magnesium plate is covered with a nanocrystal layer, the surface of the nanocrystal layer is covered with a ceramic membrane through a micro-arc oxidation technology, the novel belt-loop magnesium plate is provided with a pull rope hole and a graft hole, the pull rope hole and the graft hole both penetrate through the novel belt-loop magnesium plate, the pull rope hole is used for a pull rope to pass through, and the graft hole is used for a graft to pass through. As the main material of the novel belt-loop magnesium plate is magnesium, magnesium ions of the novel belt-loop magnesium plate can play a role in promoting osteogenesis, so that the formation of callus at the thighbone part is accelerated, the micromotion of a tendon graft in a bone tunnel is slowed down, the widening of the bone tunnel is inhibited, and the reconstruction success rate is improved; and the problems of insufficient mechanical property and poor corrosion resistance of magnesium metal can be solved through the nanocrystal layer and the ceramic membrane, so that the problems of unstable fixation and bone tunnel expansion of an existing tendon graft are practically solved.

Description

Technical field [0001] The present invention relates to the medical field, particularly relates to novel magnesium plate for a belt loop having high strength and corrosion resistance. Background technique [0002] The anterior cruciate ligament (Anterior Cruciate Ligament, referred to as ACL) reconstruction usually hamstring grafts alternatively torn ligament, this surgical procedure was a good clinical results. It is reported that the tendon graft fixed to the tibial side of the common interface screw, fixed to the femoral common steel belt loop (endobutton). At present, the inert metal plate is a band loop, a lack of biological activity, only play physically fixed effects. After ACL reconstruction, bone tunnel of clinical problems, easily lead to tendon graft fixation instability. [0003] The main reason may be a polyester sheet with a loop connected to drive ring moves tendon transplant in the bone tunnel. After the bone tunnel widening tendon graft fixation may appear loose ...
