Dual Compression Locking Screw-Plate System

Abstract

The invention provides a double-pressure locking bone-setting nail plate system. The double-pressure locking bone-setting nail plate system comprises a first fixing part (1) and a second fixing part (2), wherein the first fixing part (1) and the second fixing part (2) are integrally formed, fixedly connected or detachably connected; the first fixing part (1) comprises a main bone plate (101), anda main rod locking hole (110) and a pressurizing hole (112) are arranged on the main bone plate (101) ; the second fixing part (2) comprises one or more bone plates (201), and the bone plate (201) isfixedly connected with a secondary nail (202) ; the bone plate (201) includes a wave-shaped part (203). The double-pressure locking bone-setting nail plate system adopts Y-shaped nail design, and hasthe advantages of angular fixation, greater fixation strength and higher axial stability, inverted stabbing structure on the auxiliary nail, convenient knocking and implantation, higher pullout resistance after implantation, and double pressure effect through deformation of wave-shaped part and pressurizing hole to effectively prevent fracture gap formation.

Description

Technical field [0001] The present invention relates to the field of medical equipment, in particular to a double compression locking bone nail plate system. Background technique [0002] Metaphysis: There are long bones in the bones, such as the femur and tibia of the lower limbs and the humerus and radius of the upper limbs [0003] Before long bones are formed, cartilage forms the embryonic shape of the bone, then ossifies and hardens, and finally forms cartilage at both ends. The cartilage continues to ossify and grow. Finally, an epiphyseal line is formed between the cartilage and bone at both ends of the bone. The line between bone and cartilage, the metaphysis is that part. [0004] At present, there is no bone plate specially designed for children's metaphyseal fractures. The traditional bone plate has a large area, which is easy to interfere with the articular surface, and the implanted screw is large. The implantation damages the metaphysis and is not conducive to the heal...

AI Technical Summary

Problems solved by technology

[0004] 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
