Compression Screw Plate System

Abstract

The invention provides a compression bone-set plating system, which comprises a first fixing portion (1) and a second fixing portion (2), wherein the first fixing portion (1) and the second fixing portion (2) are integrally formed, fixedly connected or detachably connected; the first fixing portion (1) comprises a main bone plate (101), and the main bone plate (101) is fixedly connected with a main nail (102) ; the second fixing portion (2) comprises a plurality of supporting bone plates (201), and a secondary nail (202) is fixedly connected on the supporting bone plates (201) ; the supportingbone plates (201) include a wave-shaped portion (203). According to the invention, the Y-shaped nail plate is adopted, and the bone blocks are fixed at angles after implantation, the fixing strengthis larger, and the axial stability of the fracture is higher; a barbed structure is adopted on the main nail and the secondary nail, the tapping is carried out to implant, the implantation is convenient, and the anti-pulling force is higher; the barbed nail has small bone damage on the metaphysis of the children, needs little bone mass, and reduces the interference of internal plants on the healing and development of the metaphysic fracture; the bending of wave-shaped portion can also serve as a pressurizing effect to prevent the formation of fracture gaps.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a pressurized bone nail-plate system. Background technique [0002] Metaphysis: The long bones in the skeleton, such as the femoral tibia of the lower limbs and the humerus ulna and 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 bone plate specially designed for metaphyseal fractures in children at home and abroad. The traditional bone plate is easy to interfere with the articular surface due to the large area of ​​the plate; the implanted screw body is large, and it will cause great dama...

AI Technical Summary

Problems solved by technology

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