Problems solved by technology

However, due to the strong force that the human knee ligament bears during exercise, the reconstruction of the ligament inevitably has problems such as the "wiper effect" that swings like a car wiper after being fixed, and the "bungee effect" that stretches and rebounds after being fixed.

Embodiment

[0049] figure 1 with image 3 Two structural schematic diagrams of the ligament reconstruction and fixation device provided in this embodiment, wherein, image 3 The ligament reconstruction fixation device does not show ligaments; figure 2 with Figure 4 It is a schematic diagram of the scene structure of the ligament reconstruction fixture. In order to show the structure more clearly, the ligament reconstruction fixture in the figure is processed in perspective.

[0050]This embodiment provides a ligament reconstruction fixation device, which is applied to ligament repair and reconstruction, especially to ligament repair and reconstruction in cruciate ligament injury.

[0051] see Figure 1-Figure 4 As shown, the ligament reconstruction fixation device includes a ligament fixation structure 100 and a ligament 200;

[0052] The ligament fixation structure 100 is connected to one end of the ligament 200;

[0053] Along the direction perpendicular to the extension of the ...

Abstract

The invention discloses a ligament reconstruction fixing device and a using method thereof, which relate to the technical field of medical instruments. The ligament reconstruction fixing device comprises a ligament fixing structure and a ligament, the ligament fixing structure is connected with one end of the ligament; and a maximum size of the ligament fixing structure is larger than the size ofthe ligament in the direction perpendicular to the extending direction of the ligament. The using method comprises the following steps that a bone tunnel is opened in the preset positions of the thighbone and the tibia; pulling the ligament of the ligament reconstruction fixing device into the bone tunnel from the outer side of the femoral cortex to the tibia side until the ligament fixing structure is matched with the femoral outer side section of the bone tunnel; after one end of the tibia side of the ligament is pulled to a certain tension, the tibia end of the ligament is fixed on the tibia. According to the ligament reconstruction fixing device and the using method thereof, the problems of the windshield wiper effect and the bungee jumping effect in the prior art are solved to a certain extent, and the stability of ligament reconstruction is improved to a certain extent.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ligament reconstruction fixation device and a method for using the same. Background technique [0002] Cruciate ligament injury is a common joint injury in clinical practice, usually caused by severe joint twisting. Improper treatment can lead to joint instability and secondary damage to the joint, thereby affecting the performance of the joint. Surgical reconstruction is an important option for cruciate ligament injuries, usually by reconstructing the ligament that connects the femoral and tibial ends. [0003] In the prior art, after the reconstruction ligament passes through the femur, one end of the reconstruction ligament is connected to a titanium plate and a U-shaped nail to achieve limited fixation of the reconstruction ligament on the femur. However, due to the strong force that the human knee ligament bears during exercise, the reconstruction of the ligament ...
