Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of bone fracture plates, and in particular relates to an anatomical femoral locking bone fracture plate. Background Art
[0002] Distal femoral fracture refers to fracture within 10 cm of the lower end of the femur. According to the A0 classification, it is divided into A, B, and C fractures. Fractures treated with plates mainly include type A supracondylar femoral fractures and type C intra-articular fractures. Locking plates are a new internal fixation method that has emerged in the past 10 years. Its advantages are: it is designed according to anatomy, can lock between nails and plates, and is minimally invasively inserted percutaneously. Inserting screws through an aimer can significantly reduce surgical trauma and protect fracture blood supply. The main indications for locking plates are distal shaft fractures, supracondylar femoral fractures, and distal intra-articular fractures.
[0003] When in use, the existing locking plate is placed on one side of the femur and fixed with a locking screw, but has the following defects: (1) The length of the existing locking plate is fixed. During bone fixation, due to the inconsistent position of the femur, the length of the plate cannot be adjusted accordingly, resulting in a certain deviation in the locking position of the femur and a restriction on the installation position. For this reason, we propose an anatomical femoral locking plate. Utility Model Content

[0013] (1) Through the designed adjustment sleeve, adjustment plug plate, latch hole and clamp block, the traditional bone plate is split into two parts through the adjustment sleeve and the adjustment plug plate, which can be adjusted flexibly. When adjusting the overall length of the bone plate, the first bone plate body and the second bone plate body are pulled, and the adjustment plug plate slides in the adjustment sleeve and is adjusted to a suitable length. Then the clamp block is inserted into the latch hole so that both sides of the clamp block are clamped in the tooth grooves of the two side walls of the latch hole, so that the overall length of the bone plate is locked and fixed, ensuring that when the utility model is used for femoral locking, its length can be adjusted and adapted arbitrarily, avoiding a certain degree of misalignment of the femoral locking position due to the fixed length of the traditional bone plate. The deviation and the installation position are limited, so that the utility model can accurately lock the femur, and the locking position is not limited by length.
