Abstract

The invention discloses a tibia medial plateau bone fracture plate which comprises a bone fracture plate body, the bone fracture plate body is divided into a far plateau section, a middle section and a near plateau section, and the near plateau section is of an arc-shaped structure and a slope structure. The near plateau section is sequentially provided with a near-plateau upper kirschner wire hole, a near-plateau upper locking hole, a near plateau lower kirschner wire hole and a near plateau lower locking hole from left to right, the middle section is in a plane design and accords with a tibia backbone anatomical structure, the middle section is sequentially provided with a sliding hole and a plurality of middle locking holes from left to right,. A middle Kirschner wire hole is formed between every two adjacent middle locking holes, and the far platform section is sequentially provided with a sliding hole I, a far platform locking hole and a far platform Kirschner wire hole from left to right. The width and the curvature are designed according to an anatomical structure of a tibia medial platform, and the device is an anatomical locking plate and can be tightly attached to bone cortex without intraoperative shaping, so that the strength of the bone fracture plate cannot be reduced, and the operation time cannot be prolonged.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a tibial medial platform bone plate. Background technique

[0002] The medial tibial plateau fracture is a fracture caused by violence on the contact surface between the tibia and the lower end of the femur. The tibial plateau is an important load-bearing structure of the knee. Once a fracture occurs, the force on the inner and outer platforms will be uneven, and osteoarthritis will easily occur over time. Medial tibial plateau fractures are common in adolescents and can easily lead to meniscal injury and cruciate ligament injury. In severe cases, bone plate reduction and fixation surgery will be used. The commonly used bone plates in the treatment of medial tibial plateau fractures are dynamic compression DTS bone plate and anatomical bone plate, but the existing dynamic compression DTS bone plate and anatomical bone plate have many shortcomings, for example: dynamic co...

Examples

Embodiment 1

[0018] Such as Figure 1-Figure 3 A tibial medial plateau bone plate is shown, comprising a bone plate body 1, the bone plate body 1 has a T-shaped structure as a whole, the bone plate body 1 has a thickness of 0.2-0.4 cm, a length of 7-20 cm, and a width of 1.1-1.3cm, the bone plate body 1 is divided into a far platform segment 2, a middle segment 3 and a proximal platform segment 4, the proximal platform segment 4 adopts an arc-shaped structure and a slope structure, which conforms to the anatomical structure of the medial tibial platform. The near-platform section 4 is successively provided with a Kirschner wire hole 5 on the near platform, a locking hole 6 on the near platform, a lower Kirschner wire hole 7 near the platform, and a lower locking hole 8 near the platform. The pinhole 5 and the upper locking hole 6 near the platform are located on the arc structure, the lower Kirschner wire hole 7 near the platform and the lower locking hole 8 near the platform are located o...

Embodiment 2

[0020] Such as Figure 1-Figure 3 A medial tibial plateau bone plate is shown, including a bone plate body 1. The bone plate body 1 has a T-shaped structure as a whole. Friction damage and foreign body sensation, the bone plate body 1 has a thickness of 0.2-0.4 cm, a length of 14-20 cm, and a width of 1.1-1.3 cm. The bone plate body 1 is divided into a distal platform section 2, a middle section 3 and a near The platform section 4, the near-platform section 4 adopts an arc-shaped structure and a bevel structure, which conforms to the anatomical structure of the medial tibial platform, facilitates the insertion of the bone plate body 1, does not require shaping, and reduces surgical steps and time. From left to right, there are Kirschner wire holes 5 on the near platform, locking holes 6 on the near platform, lower Kirschner holes 7 near the platform, and locking holes 8 near the platform. The locking hole 6 on the platform is located on the arc structure, and there are two Ki...
