Anatomical individualized dynamic physiological bone pressurizing, locking and setting plate

Abstract

The invention provides an anatomical individualized dynamic physiological bone pressurizing, locking and setting plate and belongs to the technical field of bone treatment instruments. The anatomical individualized dynamic physiological bone pressurizing, locking and setting plate aims at solving the problem that when an existing bone setting plate is used for fixing a fractured bone, stress shielding causes bone absorption at the broken ends of the fractured bone and nonunion of the fractured bone, and the bone setting plate is easily bent or easily breaks and the problem that the bone setting plate is large in external fixing volume and is inconvenient to carry after operation. The in-vivo external bone setting plate comprises an anatomical individualized locking plate, a right-angle fixing plate, a right-angle pressurizing plate and a physiological pressurizer, wherein the right-angle fixing plate and the right-angle pressurizing plate are installed in the middle of the anatomical individualized locking plate, the physiological pressurizer is installed between the vertical plate of the right-angle fixing plate and the vertical plate of the right-angle pressurizing plate, the anatomical individualized locking plate is provided with multiple screw holes, bone locking screws are installed in the screw holes, and the area, corresponding to the physiological pressurizer, of the anatomical individualized locking plate is an area free of holes and slots. The anatomical individualized dynamic physiological bone pressurizing, locking and setting plate is mainly used for internal and external fixation treatment of the fractured bone.

Description

technical field [0001] The present invention relates to a bone plate, in particular to an anatomically individualized dynamic physiological bone compression locking bone plate, which is used for internal and external fixation of fractures in various parts of the limbs of the human body, and is especially suitable for fracture nonunion anatomical dynamic physiological bone compression A locking osteosynthetic treatment belongs to the technical field of bone treatment instruments. Background technique [0002] Currently there is no anatomical individualized dynamic physiologic bone compression locking plate. The existing bone compression locking bone plates and bone compression fixation plates cannot achieve the purpose of physiological bone compression, and the design of several holes for fixing locking screws on various bone plates does not meet the load-bearing and bending resistance mechanics of fixed fracture ends. The principle is that they are all installed at the part...

Problems solved by technology

[0004] 1. Several fixing screw holes on the existing bone plate are evenly arranged. There are also holes in the fracture site that needs to be fixed and the fracture-resistant bending part, so that the bone plate is thin and the bending resistance is reduced at the fixed fracture site, so it cannot be firmly fixed. Immobilization of the fractured end while bending or breaking of the plate occurs (see Figure 1-Figure 12 )

[0005] 2. There are still bone plates that need to bear weight, and the part that bears bending resistance is designed with long and wide holes (see Figure 5 , Figure 11 ), thus burying hidden dangers for the fixation of the broken end of the fracture, resulting in frequent fracture of the long and wide holes of the bone plate during clinical application (see Figure 12 ), taking the middle 1 / 3 fracture of the femur as an example, analyze the shear force and bending force (see Figure 1-Figure 3 ), the lever arm of the lower limbs is long, affected by gravity, the movable steel plate is easy to break after operation

[0006] 3. The existing orthopedic experts are all dreaming of having a bone plate that can really achieve the compression of the broken end of the bone, but the existing bone compression plate (see Figure 4-Figure 12 ) cannot achieve the effect of bone compression, resulting in bone resorption at the fracture end, bone defect, and plate fracture often occurs

The bone plate designed for decades does not meet the clinical needs and is out of clinical operation. They are only experts in mechanical design, do not understand and do not participate in clinical operation
