Locking compression nail plate system for setting bone

Abstract

The invention provides a locking compression nail plate system for setting a bone. The system comprises a first fixing part (1) and a second fixing part (2). The first fixing part (1) and the second fixing part (2) are integrally formed and fixedly connected or detachably connected; the first fixing part (1) comprises a main bone plate (101), and a main rod locking hole (110) is formed in the mainbone plate (101); the second fixing part (2) comprises multiple branch bone plates (201), and auxiliary nails (202) are tightly fixed to the branch bone plates (201); the branch bone plates (201) include wavy parts (203). A Y-shaped nail plate design is adopted, a bone block is fixed at an angle after the system is implanted, the fixation strength is higher, and the axial stability of bone fractures is higher; a main nail and the auxiliary nails are of inverse thorn structures, the system is implanted by knocking, implantation is convenient, and a pull-out resistant force is higher; the inverse thorn-liked nails have less damage to metaphysis sclerotin of children, less bone amount is needed, and interference of internal implants on healing and development of metaphyseal bone fractures isreduced. By bending the wavy parts, the effect of pressurization can also be achieved to prevent formation of bone fracture gaps.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a locking and pressing bone nail-plate system. Background technique [0002] Metaphysis: There are long bones in the bones, such as the femur tibia of the lower limbs and the humerus ulnar radius of the upper limbs. Before the formation of long bones, cartilage first forms the embryonic form of bone, then ossifies and hardens, and finally forms cartilage at both ends, and the cartilage continues Ossification, growth, and finally the epiphyseal line is formed between the cartilage and bone at both ends of the bone, that is, the line between bone and cartilage, and the metaphysis is that part. [0003] At present, there is no bone plate specially designed for metaphyseal fractures in children. The traditional bone plate has a large area, which is easy to interfere with the articular surface, and the implanted screw body is large, which will cause great damage to the metaphysis du...

Problems solved by technology

[0003] At present, there is no bone plate specially designed for metaphyseal fractures in children. The traditional bone plate has a large area, which is easy to interfere with the articular surface, and the implanted screw body is large, which will cause great damage to the metaphysis during implantation, which is not conducive to the healing and development of the metaphysis. development; and when the screw is fixed, due to the large body of the screw, the screw may split the metaphyseal bone, resulting in failure to fix the fracture or bone malunion
