The fixing mode of the bone fracture plate mainly comprises screw fixing, binding fixing and the like. In order to ensure the stability of the relative positions of bones and avoid the occurrence of activities, bone plates are commonly made of materials and structural shapes with higher hardness so as to ensure the fixing effect, and have high stability in human bodies. With the gradual healing of the patient's bone, the bone plate may be removed at a later stage.
However, in the treatment of the bone fracture of teenagers, the traditional bone fracture plate can play a good role in the early stage, but the bone fracture plate is too stable and is easy to limit the normal growth of bones due to the fact that the teenagers are in a rapid growth and development period, so that the bone development of the teenagers is asymmetric.
Disclosure of Invention
The invention aims to provide a bone plate structure so as to solve the problem that the bone plate in the prior art is too stable to limit the normal growth of bones.
In order to achieve the above purpose, the invention provides a bone plate structure, which comprises a sliding rail and a plurality of bone plates, wherein the bone plates are arranged on the sliding rail, two adjacent bone plates are connected through a connecting piece, and the connecting piece can be ablated after being implanted for a preset time to separate the two adjacent bone plates.
Further, the sliding rails are two in parallel arrangement, and the plurality of bone plates are arranged between the two sliding rails.
Further, a dovetail groove is formed in the sliding rail, and a sliding block matched with the dovetail groove is arranged on the bone fracture plate.
Further, the plurality of bone plates includes two end plates and at least one connecting plate disposed between the two end plates, the end plates and the connecting plate being connected by a connector.
Further, the connecting plates are multiple, and the connecting plates are connected through connecting pieces.
Further, two screw holes are formed in the connecting plate and are arranged in a staggered mode.
Further, the screw holes are countersunk holes.
Further, the connecting piece is made of degradable biological materials.

Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other. The application will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 to 4, the bone plate structure of the present embodiment includes a sliding rail 10 and a plurality of bone plates 20, the plurality of bone plates 20 are disposed on the sliding rail 10, two adjacent bone plates 20 are connected by a connecting member 30, and the connecting member 30 can be ablated after implantation for a preset time to separate the two adjacent bone plates 20.
The connector 30 may be made of a degradable biomaterial suitable for implantation in a living being, such as magnesium alloy, degradable polymer material, etc., which is dissolved or degraded after being implanted in the living being for a period of time, thereby losing the connection and allowing the bone plate 20 to freely slide in the sliding rail 10. The bone plate 20 may be made of a relatively stable medical material such as titanium alloy, ceramic or polymer material and provides adequate fixation and support to the patient's bone during the initial stages of implantation.
By applying the technical scheme of the embodiment, the connecting piece 30 loses the function of connecting the two adjacent bone plates 20 after the preset time, so that the bone plates 20 can slide in the slide rail 10 along with the growth of bones of a patient, and the limitation of the bone plates in the growth direction of the bones of the patient is weakened, thereby avoiding the problem of asymmetric bone development of teenagers. Meanwhile, the sliding rail still plays a certain supporting and fixing role on the bone fracture plate 20 and bones, and secondary injury is avoided.
The specific degradation time of the connector 30 may be set according to the characteristics of the degradation material of the specific application and the physical and bone conditions of the patient themselves.
Preferably, as shown in fig. 3, the sliding rails 10 of the present embodiment are two sliding rails 10 disposed in parallel, and a plurality of bone plates 20 are disposed between the two sliding rails 10. The slide rail 10 is provided with a dovetail groove 11, and the bone fracture plate 20 is provided with a slide block matched with the dovetail groove 11. The dovetail groove 11 of the slide rail 10 can limit the moving direction of the bone plate 20, can effectively prevent the bone plate 20 from separating from the slide rail 10, and ensures the stability of the bone plate structure and the fixing effect.
As shown in fig. 1, the bone plate 20 of the present embodiment includes two end plates 22 and a plurality of connection plates 21, the end plates 22 being disposed at both ends, the connection plates 21 being disposed between the two end plates 22, the connection plates 21 and the end plates 22 being connected between the two adjacent connection plates 21 by the connection members 30. The number of the connecting plates 21, the length of the end plates 22 and other factors can be increased or decreased according to the actual condition of a patient, so that the bone plate structure can provide enough supporting and fixing effects in the bone growth process of the patient, and the condition that the end plates 22 are separated from the slide rail 10 can not occur.
The connecting plate 21 and the end plate 22 are curved towards one side of the bone to improve the fit between the connecting plate and the bone; the sides of the connecting plate 21 and the end plate 22 remote from the bones are also curved to increase the contact area with the surrounding soft tissue to reduce discomfort caused by sharp edges.
In the bone plate structure of the present embodiment, one screw hole 23 is provided on each end plate 22, and two screw holes 23 are provided on each connecting plate 21, with the two screw holes 23 being offset. Preferably, screw holes 23 are countersunk so that the heads of the bone screws are hidden within the bone plate 20 when the bone screws are implanted into the bone, reducing irritation of the heads to soft tissue surrounding the patient's bone, reducing pain, and improving comfort. The sliding rail 10 is not in direct contact with bones, the extension of the bone fracture plate 20 is not affected, and a certain resistance exists between the dovetail groove 11 and the bone fracture plate 20, so that the sliding rail 10 cannot slide out of the bone fracture plate 20.
