In the prior art, the two sides of the head of the small locking plate are provided with sharp hooks, so that the small locking plate can be firmly and firmly fixed on bones while wrapping the inner ankle protrusion. However, the current tibia far-end inner side locking bone fracture plate has fixed anatomy, and the fixed angle locking holes and the combining holes cannot be adjusted according to specific fracture conditions. In this regard, a more reasonable technical solution is also needed to solve the current technical problem.

According to the technical scheme, in the fixing process of the locking hole at the first end, the distal end of the tibiofibular bone is reset and fixed by the reset forceps and the Kirschner wire at the same time, the drill bit is used for punching through the tibiofibular bone by the guide, the half-thread hollow locking bone screw with proper length is selected to be screwed into the locking hole, the threaded part is screwed into the fibular bone, the screw head is locked in the locking hole, and the fixation of the combined relative position of the tibiofibular bone is ensured. The universal hole design of the adjusting hole is convenient for doctors to adjust the angle of the screw driving according to specific fracture conditions, the preoperative planning is more flexibly carried out, and the phenomenon of nail collision in the using process is avoided. The tibia far-end combined locking plate has smaller overall volume, can avoid strong foreign body sensation after being implanted into the convex part of the tibia far-end inner ankle, prevents irritation to surrounding tissues, and is beneficial to improving the comfort of patients in operation based on the design of the small plate type.
Additional features and advantages of the utility model will be set forth in the detailed description which follows.

Detailed Description
The following describes specific embodiments of the present utility model in detail with reference to the drawings.
According to an embodiment of the present utility model, a distal tibial joint locking plate is provided. The distal tibial locking plate is designed primarily for tibiofibular joint injury, with one particular embodiment shown in fig. 1.
Referring to fig. 1, the tibia distal end combined locking plate comprises a plate body 1, wherein the plate body 1 is provided with a first end and a second end which are opposite, and the first end is provided with a locking hole 2 for driving a screw; the second end is provided with a combining hole 3, so that the operation is convenient to select pressurizing and locking; an adjusting hole 4 is arranged between the combining hole 3 and the locking hole 2, the inner wall of the adjusting hole 4 is provided with an inclined plane, at least two guide grooves 5 which are obliquely arranged are formed in the inclined plane, and the included angle alpha of the guide grooves 5 relative to the axial lead of the adjusting hole 4 is 10-30 degrees, so that the guide screw can be reliably driven into broken bones at a uniform speed.
Through the technical scheme, in the fixing process of the first end locking hole 2, the distal end of the tibiofibular bone is reset and fixed by the reset forceps and the Kirschner wire at the same time, the tibiofibular bone is perforated and penetrated by the drill bit through the guide, the half-thread hollow locking bone screw with proper length is selected to be screwed into the locking hole 2, the threaded part is screwed into the fibular bone, the screw head is locked in the locking hole 2, and the fixation of the combined relative position of the tibiofibular bone is ensured. The universal hole design of the adjusting hole 4 facilitates doctors to adjust the driving angle of the screw according to specific fracture conditions, preoperative planning is more flexibly carried out, and meanwhile, the phenomenon of nail collision in the using process is avoided. The tibia far-end combined locking plate has smaller overall volume, can avoid strong foreign body sensation after being implanted into the convex part of the tibia far-end inner ankle, prevents irritation to surrounding tissues, and is beneficial to improving the comfort of patients in operation based on the design of the small plate type.
It should be noted that, although the screws are the standard components, the screws in the above description are named the same, those skilled in the art may still select screws with different specifications according to actual situations, so as to be able to effectively cooperate with the corresponding holes.
