[0002] With the development of the medical field, in orthopedics, in order to fix the fracture site of the patient, bone screws or internal locking plates are often used to fix the fracture site of the patient. The locking plate is a fracture fixation device with a locking threaded hole. It is used in conjunction with a screw with a threaded head to fix it at the fracture site and relies on the locking plate's own interlocking structure to achieve fixation of the fracture site.

[0003] Patent document CN203576615U discloses an internal locking plate for toe bone fractures, including a plate body, wherein the plate body includes an upper portion and a bottom portion connected by an integral arc transition, wherein the upper portion and the bottom portion are in an oblique L-shape, and the bottom portion is in an 8-shape, and threaded locking holes are provided on the upper portion and the bottom portion. Due to the adoption of the above technical solution, the utility model has the advantages and positive effects of being conducive to the healing of broken bones, enabling patients to recover as soon as possible, and facilitating doctors' operations.

[0004] The above-mentioned internal locking plate for phalanx fracture enhances its fixation effect on the broken bone by means of the oblique L-shaped and 8-shaped structures. The existing internal locking plate is not firmly fitted with the bone surface when in use, which may cause harm to the patient. At the same time, most of the existing internal locking plates are plate bodies. Since the shape of the phalanx changes from thick to thin, the front end of the internal locking plate is prone to not fit firmly enough when fixing. Based on the shortcomings of the existing technology, the utility model designs a new distal radius steel plate. Utility Model Content

[0027] Please refer to Figure 1 , Figure 3 When used specifically, the auxiliary locking mechanisms 8 provided on both sides of the bone plate 1 can enable it to be well fitted and fixed with the thinner end of the toe bone, so that the locking effect of the right end of the locking plate is also better, thereby achieving the purpose of improving the locking effect of the locking plate on the fracture.

[0028] Four left threaded holes 3 are provided on the end 2, five locking holes 4 are provided on the bone plate 1, a right threaded hole 5 is provided on the right end of the bone plate 1, auxiliary fixing plates 6 are provided on both sides of the center of the bone plate 1, and plate holes 7 are provided on the auxiliary fixing plates 6.

[0029] Please refer to Figure 1 When used specifically, the bone plate 1 can be better fixed on the toe bone through the five locking holes 4 provided on the bone plate 1 and the two auxiliary fixing plates 6 on both sides of the bone plate 1, so that the locking is more secure.

[0030] Both sides of the bone plate 1 are provided with arcuate edges 101 , and both arcuate edges 101 are provided with mounting grooves 102 . Both mounting grooves 102 are fixedly connected with fixed shafts 103 . The two auxiliary locking mechanisms 8 are movably sleeved on the two fixed shafts 103 through plate sleeves 802 .

[0031] Please refer to Figure 3 When used specifically, the arcuate edges 101 on both sides of the bone plate 1 make the fitting surface between the bone plate 1 and the phalanges smoother, thus avoiding scratches on the surface of the phalanges during installation.

[0036] Please refer to Figure 3 When in use, the triangular distribution of the four left-end threaded holes 3 makes the left end of the plate more firmly fixed and less likely to loosen. At the same time, the fan-shaped structure at the left end of the end portion 2 increases the fitting area with the toe bone, and the rounded corners at the upper ends of the left-end threaded hole 3, the locking hole 4, the right-end threaded hole 5 and the plate hole 7 make the upper surface of the bone plate 1 smoother.

[0037] Working principle and use process of the utility model: During the use of the utility model, the bone plate 1 is placed on the phalanx fracture, so that the end 2 of the left end of the bone plate 1 is set at the thicker end of the phalanx, and the right end of the bone plate 1 is placed at the thinner end of the phalanx, and then the position of the locking plate is adjusted to be set at a better position for fixing the fracture site, and then screws are respectively screwed into the four locking holes 4 on the bone plate 1 to fix the bone plate 1 on the phalanx, and then screws are screwed into the four left end threaded holes 3 on the end 2 to fix the left end of the bone plate 1, and then the auxiliary A screw is screwed into the plate hole 7 opened on the fixing plate 6 to fix the middle part of the bone plate 1. Finally, the auxiliary locking mechanism 8 is slightly rotated to make the plate body 801 and the arc plate 807 fit well with the front end of the phalanx. Then a screw is screwed into the fixing hole 809 to fix the arc plate 807, so that the auxiliary locking mechanism 8 is locked and connected to the phalanx. At the same time, a screw is also screwed into the threaded hole 5 at the right end to lock the right end of the phalanx. The inner locking plate can firmly fix the fracture site of the phalanx, which is beneficial to the recovery of the fracture site.
