Problems solved by technology

[0002] At present, most bone plates used for surgical orthopedics use strong pressure internal fixation, that is, pressure holes and pressure screws are used to pressurize the fracture end surface, and at the same time, the friction force between the bone surface and the bone plate is used to fix the fracture, which seriously affects the two sides of the fracture. poor blood supply, leading to poor quality healing, complications, and prolonged healing time

Embodiment 1

[0014] Embodiment 1, a kind of stress groove internal fixation support system, refer to figure 1 , figure 2 As shown, the system is composed of a main structure 4, seven locking holes 2, a locking pressure hole 3 and a stress groove area 1; the main structure 4 is a shuttle-shaped elongated alloy plate, the middle part of which is close to the side of the bone, The main structure presents a concave arc shape, and its concave height is 0.3mm-0.5mm, which is the stress groove area 1; the locking hole 2 and the locking pressure hole 3 are evenly distributed on both sides of the main structure except the stress groove area. plate.

[0015] During use, such as image 3 , Figure 4 As shown, through the locking hole 2, the end of the locking bone screw 6 uses locking screws to fix the internal fixation bracket system on the bone; the pressure bone screw 7 enters the bone through the locking pressure hole 3, so that the bracket system is fixed on the different fractures of the ba...

Abstract

The invention provides a fixing bracket system with a stress groove. The fixing bracket system is characterized in that the system comprises a main structure, locking holes, locking pressurizing holes and a stress groove area; the main structure is a fusiform stripped alloy plate; the middle section of the alloy plate is close to one side of a skeleton; the main structure is in a downwardly-concave arc shape; the downwardly-concave height of the main structure is 0.3mm to 0.5mm; the downwardly-concave arc part of the main structure is the stress groove area; and the locking holes and the locking pressurizing holes are uniformly distributed in the alloy plate at the two sides of the main structure except the stress groove area.

Description

technical field [0001] The invention belongs to the field of orthopedic orthopedics in clinical medicine, and in particular relates to an internal fixation bracket system. Background technique [0002] At present, most of the bone plates used for surgical orthopedics are internal fixation with strong pressure, that is, pressure holes and pressure screws are used to pressurize the fracture end surface, and at the same time, the friction between the bone surface and the bone plate is used to fix the fracture, which seriously affects the two sides of the fracture. Terminal blood supply, so the healing quality is poor, easily lead to complications, and prolong the healing time. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a stress groove internal fixation bracket system that is safe, reliable, effectively reduces complications, and accelerates fracture healing time. [0004] The techn...
