Embodiment Construction

[0034] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0035] Such as Figure 1 to Figure 4 As shown, the stress-type compression locking osteosynthesis device of the present invention includes: at least one stress-type bone plate 700, and the stress-type bone plate 700 is provided with a first locking hole 100, a second locking hole 200 and a pressure locking hole 300 , the pressurized locking hole 300 is formed by the second locked hole 200 and the pressurized hole 500 interlaced with each other, and the pressurized lock hole 300 is symmetrically distributed on the stress-type bone plate 700 according to the specific and reasonable distribution; on the upper surface of the stress-type bone plate 700 On the edge side, between adjacent first locking holes 100 , between adjacent pressurization locking holes 300 , between second locking holes 200 and pressurization locking holes 300 , there ...

Abstract

The invention discloses a stress pattern pressuring and locking osteosynthesis device. The pressuring and locking osteosynthesis device comprises at least one stress pattern bone lamella provided withfirst locking holes, second locking holes and pressuring and locking holes, and the pressuring and locking holes are formed by crossing and communicating the second locking holes and pressuring holes; gradually changing stress notches are formed at the edge side of the upper surface of the stress pattern bone lamella and between any two adjacent holes among the first locking holes, the second locking holes and the pressuring and locking holes; stress through notches are formed between the first locking holes of the stress pattern bone lamella. The gradually changing stress notches are formedin the edge side of the stress pattern bone lamella of the locking osteosynthesis device, the stress through notches are formed between the first locking holes, thus the stress resistance effect of the stress pattern bone lamella is improved, and the situation that the stress pattern bone lamella fractures because the stress of the stress pattern bone lamella is over concentrated is avoided.

Description

technical field [0001] The invention relates to the technical field of internal fixation devices for fractures, in particular to a stress-type pressurized and locked osteosynthesis device. Background technique [0002] At present, the traditional metal bone plate still has problems such as stress shielding and stress concentration. In clinical application, during the process of correcting and fixing bones with traditional metal bone plate, the metal bone plate is easy to break, so that bone nonunion and bone malunion occur from time to time. [0003] After research, it was found that almost all metal bone plate fractures occurred at the fracture site or at the corresponding screw hole closest to the fracture site. The broken screw hole occurs in the nail hole where the screw is inserted near the fracture end, or occurs in the nail hole where the screw is not inserted in the corresponding part of the fracture. However, no fracture of the metal plate occurred in the solid pa...
