Description

Bone fracture plate for fixing rear ankle fracture Technical Field The utility model relates to the technical field of bone plates, in particular to a bone plate for fixing a rear ankle fracture. Background The rear ankle fracture is a very important component part of ankle fracture, and has a high proportion, and can be frequently encountered in clinical work, and is mostly caused by the combined action of high-energy vertical violence and low-energy rotating shearing force, and the conventional treatment method of the rear ankle fracture is to fix by using a bone fracture plate, so that the strength is ensured, and meanwhile, a good fixing function can be realized. Through searching, for example, the utility model with the bulletin number of CN214761417U discloses a bone fracture plate for fixing a rear ankle fracture, wherein the tibia fixing plate is a longitudinal long plate, the bending connecting plate is an oblique long plate, the upper end of the bending connecting plate is connected to one side of the lower end of the tibia fixing plate, an included angle is formed between the plate surface of the bending connecting plate and the plate surface of the tibia fixing plate, the space between fixing screw holes for fixing is relatively fixed, and a certain position in a rear ankle bone is not suitable for being screwed, so that the number of screws on the bone fracture plate is reduced, the bone fracture plate is easy to fix and infirm, healing of the rear ankle fracture is influenced, and the treatment period is prolonged. Disclosure of utility model The utility model mainly aims to provide a bone fracture plate for fixing a rear ankle fracture, which can effectively solve the problem that the interval between fixing screw holes for fixing the bone fracture plate in the prior art is relatively fixed. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides a bone fracture plate of fixed back ankle fracture, includes the bone fracture plate body, a plurality of removal holes have been seted up to one side of bone fracture plate body, the inside of removal hole is equipped with a plurality of fixed blocks, the equal fixed mounting in surface left and right sides of fixed block has the backup pad, and two backup pads keep away from one side middle part of fixed block and all have seted up the concertina hole, two the equal fixed mounting in inside in concertina hole has the spring, and two springs are close to the equal fixed mounting of one end of concertina hole opening part and have the fixed head. Preferably, the movable grooves are formed in the left side and the right side of the inside of the movable hole, the movable holes are formed in the upper side and the lower side of the inside of the movable groove, the movable balls are movably connected to the inside of the movable holes, the fixed holes are formed in one side of the inside of the movable groove, and the fixed holes are arranged at equal intervals.
