Abstract

The invention provides a bone-setting pin-board system, which 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), and the main bone plate (101) is fixedly connected with a main nail (102) ; the second fixing part (2) comprises one or more branch bone plates (201), and the bone plate (201) is fixedly connected with a sub-nail (202) ; a plurality of bone plates (201) form an included angle or are parallel to each other in the length extension direction; a barbed structure (400) is arranged on the main nail (102) and / or the sub-nail (202). According to the invention, the Y-shaped nail designis adopted, the angle is fixed, the fixed strength is larger, and the axial stability is higher; a barbed structure is adopted on the main nail and the sub-nail, the knocking implantation is convenient, and the anti-pulling force of the nails after being implanted is higher; the bone damage to the metaphyseal end of a child is small, the amount of bone is reduced, and the interference of the inner-implanted object to the healing and development of the metaphyseal end is reduced.

Description

technical field

[0001] The invention relates to the field of medical devices, in particular to a 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 bone plate specially designed for metaphyseal fractures in children at home and abroad. The traditional bone plate has a large area and is easy to interfere with the articular surface. Healing and development; and due to the large size of the screw during screw fixation, the s...
