Anterior and posterior cruciate ligament reconstruction under surgical arthroscopic tibial fixation device

Abstract

The invention relates to a tibia end fixing device in anterior and posterior cruciate ligament reconstruction under a surgical arthroscope. The tibia end fixing device aims at solving the problem that the burden of autogenous tendon cutting is heavy. The tibia end fixing device comprises a wiring harness ring used for connecting muscle tendon in a tibial tunnel and a titanium cable connected with the wiring harness ring, and the outer section, exposed out of the tibial tunnel, of the titanium cable is provided with a lock nut with a gasket in a fitting mode. The wiring harness ring and the titanium cable are connected in the mode that an end ring is woven at the inner end of the titanium cable and the titanium cable is connected with the wiring harness ring through the end ring in a sleeved mode, or in the mode that the wiring harness ring is connected with a U-shaped titanium steel piece in a sleeving mode, and an opening of the U-shaped piece is in rivet connection with the inner end of the titanium cable, or in the mode that the titanium cable of which the middle is dismantled back to form a U shape is connected with the wiring harness ring in a sleeved mode, or in the mode that the inner end of the titanium cable is dismantled back to form a U shape and connected with the wiring harness ring in a sleeved mode, and then the titanium cable and the wiring harness ring are fixed together through a rivet fixing sleeve. The tibia end fixing device has the advantages that the length of the muscle tendon in the tibial tunnel can be shortened, the treatment cost of a patient can be lowered, autogenous tendon cutting is reduced, operative incision does not need to be additionally performed, and operation wound is reduced.

Description

technical field [0001] The invention relates to a ligament reconstruction fixation device, in particular to a surgical arthroscopic anterior and posterior cruciate ligament reconstruction tibial end fixation device. technical background [0002] Anterior cruciate ligament injuries and posterior cruciate ligament injuries are common sports injuries. At present, the commonly used ACL reconstruction method is to take autologous semitendinosus and gracilis muscle, and fold four strands to reconstruct the ACL. The femoral end is usually fixed with button or rigidfix, and the tibial end is usually fixed with intrafix. The length of the tendon needs to be 10-12cm, and the diameter is about 7 -8mm. The posterior cruciate ligament is usually reconstructed with allogeneic Achilles tendon, but the supply source is limited and expensive. If the autologous tendon is obtained, it is often necessary to obtain bilateral semitendinosus and gracilis muscles, and four strands to reconstruct t...

AI Technical Summary

Problems solved by technology

The posterior cruciate ligament is often reconstructed with allogeneic Achilles tendon, but the supply source is limited and expensive. If the autologous tendon is obtained, it is often necessary to obtain bilateral semitendinosus and gracilis muscles, and four strands to reconstruct the posterior cruciate ligament. The femoral end is fixed with interface screws or buttons , the tibial end is double-fixed with intrafix and screws plus spacers, and the length of the tendon often needs to be 20cm
