Paraglider-shaped fixed plate device for cruciate ligament reconstruction

Abstract

The invention discloses a paraglider-shaped fixed plate device for cruciate ligament reconstruction and aims at providing a paraglider-shaped fixed plate device for cruciate ligament reconstruction of knee joints. The paraglider-shaped fixed plate device comprises an elastic fixed plate and is characterized in that the elastic fixed plate is shaped like a conical umbrella; two ends of the elastic fixed plate are connected with a suspension loop; a standby extension loop is suspended on the suspension loop; a dragging loop connected with the dragging wire is suspended at the upper part of the elastic fixed plate; and a restraint loop provided with a restraint wire is suspended at the lower part of the elastic fixed plate. The dragging wire is a double-strand semi-loop type dragging wire with the length of 250-350mm. The elastic fixed plate is an elastic titanium alloy fixed plate with the length of 9-15mm, the width of 3-4mm and the thickness of 1.2-2mm after being strutted. The paraglider-shaped fixed plate device is mainly used for knee arthroscopic cruciate ligament reconstruction.

Description

technical field [0001] The invention relates to a fixed plate device, in particular to a paraglider-shaped fixed plate device for cruciate ligament reconstruction. Background technique [0002] The cruciate ligament reconstruction paragliding fixation plate (English name: Paragliding Baffler) is used for the fixation of the ligament graft at the femoral end. Arthroscopic cruciate ligament reconstruction is a common operation in orthopedics and sports medicine. The fixation of the tibial end of the ligament graft is relatively simple and reliable, while the fixation methods of the femoral end are in various forms, each with its own shortcomings, such as the following representative ones: interface screws lead to grafting The object is flattened in the bone tunnel and the long-term healing is not good; the basis of the transverse nail fixation system is that the direction of the femoral tunnel is determined by the tibial tunnel, and it is often necessary to sacrifice the tunne...

Arthroscopic cruciate ligament reconstruction is a common operation in orthopedics and sports medicine. The fixation of the tibial end of the ligament graft is relatively simple and reliable, while the fixation methods of the femoral end are in various forms, each with its own shortcomings, such as the following representative ones: interface screws lead to grafting The object is flattened in the bone tunnel and the long-term healing is not good; the basis of the transverse nail fixation system is that the direction of the femoral tunnel is determined by the tibial tunnel, and it is often necessary to sacrifice the tunnel selection that is closer to the physiological position; Endobutton (button titanium plate) is Currently the most popular suspension-type fixation device, but the operation is relatively cumbersome: the diameter of the femoral tunnel needs to be made into a stepped shape; the bone tunnel, graft, and bone bridge (referring to the thickness of the femoral tunnel and the thinness of the outside) need to be carefully measured and calculated. The thickness of the formed step) and the length of the loop, the operation is also risky, because the steel plate is pulled up and pulled longitudinally, it is easy to pull out of the muscle periphery, and it is difficult to fully pull back and stick to the cortical bone, and it is generally inconvenient to apply to the posterior cross Ligament reconstruction
