Embodiment

[0022] Such as figure 1 As shown, the patella bone plate of the present invention includes an upper patella plate 1, an inferior patella plate 2, and two parallel patella plate screws 3, and the upper patella plate 1 and the lower patella plate 2 are connected by the patella plate screw 3.

[0023] The upper plate 1 of the patella is provided with a first hook part 2, and the lower plate 2 of the patella is provided with two second hook parts 5, and the positional relationship between the first hook part 4 and the second hook part 5 is a relative positional relationship,

[0024] Both the superior patella plate 1 and the inferior patella plate 2 are pure titanium superior patella plates, and the patella plate screws 3 are chromium patella plate screws.

[0025] In the present invention, the patella plate screw can also be 1, 3, 4, 5, 6, 7, 8, 9 or 10; Nickel patella upper plate 1 or molybdenum patella upper plate 1, patella inferior plate 2 can also be chromium inferior patel...

Abstract

The invention relates to a patella bone fracture plate for treating patella fracture and belongs to the technical field of medical instruments. The patella bone fracture plate comprises a patella upper steel plate, a patella lower steel plate and a plurality of parallel patella steel plate screws, wherein the patella upper steel plate and the patella lower steel plate are connected through the patella steel plate screws, the number of the patella steel plate screws is two, a first bent hook component is arranged on the patella upper steel plate, the patella lower steel plate is provided with two bent hook components, and the position relationship of the first bent hook component and the second bent hook components is the corresponding position relationship. The patella bone fracture plate has the advantages that the remote end bone block can be effectively fixed, patients can carry out effective function exercise, in addition, the bone fracture displacement caused during the functional exercise is avoided, the limb function disability in different degrees is avoided, simplicity and practicability are realized, and in addition, the cost is low.

Description

technical field [0001] The invention relates to a patella bone plate for treating patella fractures, belonging to the technical field of medical instruments. Background technique [0002] The patella is a bony bridge connecting the quadriceps femoris and the osseous ligament. It is an important device for protecting the musculoskeletal ankle, enhancing the strength of knee extension and stabilizing the knee joint. Patella fractures require anatomical reduction, such as comminuted fractures, especially in the distal 1 / 3 of the fracture. Due to the small size of the distal bone fragments, the existing internal fixation equipment cannot effectively grasp it, and the purpose of firm fixation cannot be achieved, so it cannot be performed. Effective functional exercise or functional exercise can cause redisplacement of the fracture, and patients with such fractures will have different degrees of functional disability of the affected limb. Therefore, there is an urgent need in thi...
