Embodiment 1

[0018] Such as Figure 1-Figure 3 A kind of distal tibial medial bone plate as shown, comprises bone plate 1, and described bone plate 1 conforms to the anatomical shape characteristic of distal tibial medial side, and described bone plate 1 thickness is 0.15-0.4cm, and length is 15-25cm, and width 1.2-2.0cm, the bone plate 1 is divided into the proximal end 2 of the bone plate and the distal end 3 of the bone plate, the proximal end 2 of the bone plate is far away from the ankle joint, the distal end 3 of the bone plate is close to the ankle joint, and the distal end 3 of the bone plate is far away from the ankle joint. The end 3 is curved upwards relative to the proximal end 2 of the bone plate, and the two are smoothly transitioned and connected, forming an integrated structure. From right to left, there are proximal Kirschner wire hole 4, proximal locking hole 5, proximal sliding hole 6, proximal lower locking hole 7 and proximal sliding hole I8. The proximal lower locking...

Abstract

The invention discloses a tibia far-end inner-side bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body is divided into a bone fracture plate near end and a bone fracture plate far end, the two sides of the bone fracture plate far end are bent inwards, and the bone fracture plate near end is sequentially provided with a near-end kirschner wire hole, a near-end locking hole, a near-end sliding hole, a near-end lower locking hole and a near-end sliding hole I from right to left; A plurality of near-end lower locking holes is arranged. Near-end lower kirschner wire holes are formed between the adjacent near-end lower locking holes, a far-end locking hole, a far-end kirschner wire hole, a far-end upper locking hole, a far-end upper kirschner wire hole and a far-end lower locking hole are sequentially formed in the bone fracture plate far end from right to left, and the far-end lower locking hole is distributed in an annular structure. A far-end middle locking hole is formed in the middle of the annular structure, and far-end lower kirschner wire holes are formed in the periphery of the far-end lower locking hole. The near end and the right end of the bone fracture plate are designed to be inclined surfaces, so that the bone fracture plate can be conveniently inserted, an operator can operate conveniently, and soft tissue injury is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a tibial distal medial bone plate. Background technique [0002] Distal tibial fractures refer to the fracture line located at the distal end of the tibia. Affected by too little soft tissue in the distal tibia and impaired blood supply, complications such as soft tissue necrosis, delayed healing, and infection are prone to occur, and the prognosis is poor. Fractures of the distal tibia are a difficult point in clinical fracture management. Due to the lack of muscle coverage and thin soft tissues at this site, complications such as soft tissue necrosis, fracture nonunion, and infection are prone to occur during fractures. At present, internal fixation is often used for the treatment of such fractures. However, there are many problems in the existing bone plate, for example: during open reduction, the bone plate will further aggravate the local soft tissue injury and ...
