Embodiment 1

[0018] like Figure 1 - Figure 3 A novel tibia rear outer platform bone plate, including a bone plate body 1, and the bone plate body 1 is integrally being L-shaped, divided into near-platform segments 2 and the remote stage 3, the bone plate body thickness of 2 -2.5MM, the length is 3.3-5.3 cm, the width is 0.8-3.3cm, the near platform segment 2 is a curved curved arch structure, in line with the inside of the tibia, and the far platform section 3 adopts a bevel Structure 4 and the planar structure 5, the bevel structure 4 is smoothly connected to the near-platform segment 2, and the near platform segment 2 has near to bottom, and the near-platform lock hole 6 and the near-platform lock hole 7 are seated from top to bottom. The platform lock hole 7 has a plurality of arrangement along the near stage segment 2, and the far platform segment 3 opens from top to bottom, and the upper platform is on the upper platform on the upper platform, the upper platform is locked. 9, The remote l...

Embodiment 2

[0020] like Figure 1 - Figure 3 A new type of tibia, a rear outer platform, including a bone plate body 1, and the bone plate body 1 is integrally in shape, and the bone plate body 1 is close to the tibial platform portion according to the position when the bone plate body 1 is used. For near platform 2, it is far from the tibial platform portion as a remote platform section 3, and the edge of the bone plate body 1 is a smooth curved surface structure, which can reduce tendon, ligament, soft tissue friction damage and foreign body sensing, the bone plate body thickness. It is 2-2.5 mm, the length is 3.3-5.3cm, the width is 0.8-3.3cm, the near platform 2 is a curved curved curved curved structure, which is in line with the inside of the tibia, and the near platform 2 2 The thin design is thinner, the thinner is 2mm, which can reduce the friction damage of tendons, ligaments, soft tissues, which uses a slope structure 4 and a planar structure 5 to facilitate the insertion of the bon...

Abstract

Disclosed is a novel bone fracture plate for a tibia posterior lateral plateau which comprises a bone fracture plate body, the whole bone fracture plate body is in an L shape and is divided into a near plateau section and a far plateau section, the near plateau section is of an inwards-bent cambered surface structure and conforms to the anatomical structure characteristics of the tibia posterior lateral plateau, and the far plateau section is of an inclined surface structure and a plane structure. The inclined surface structure is smoothly connected with the near plateau section, the near plateau section is sequentially provided with near plateau kirschner wire holes and near plateau locking holes from top to bottom, and the near plateau locking holes are distributed in a row along the near plateau section. the far plateau section is sequentially provided with a far plateau upper kirschner wire hole, a far plateau upper locking hole, a far plateau lower locking hole and a far plateau lower kirschner wire hole from top to bottom. The width and the curvature are designed according to the anatomical structure of the posterior lateral platform of the tibia, and the invention is an anatomical locking plate and can be tightly attached to the bone cortex without intraoperative shaping, so that the strength of the bone fracture plate is not reduced, and the operation time is not prolonged.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, and more particularly to a novel tibial outer platform bone plate. Background technique [0002] A typical injury mechanism of the outer fracture of the tibial platform is a knee joint to be rushed and axially jointly violent when buckling or semi-flexion. Due to the backward force of the flexural tibia platform, the outer cascade of the femur hits the outer side of the tibial platform, causing the site to fracture. The outer fracture of the tibial platform can occur alone or in combination with other part of the tibial platform. The outer fracture of the simple tibial platform is surrounded on the X-ray film, sometimes it is only lowered or increased for the outer tibial platform, which is easy to mishand. Clinically, when the outer fracture of the tibial platform is more severe, the fracture end is usually fixed in a manner in which the bone plate anatomy is fixed. There are many dis...
