Problems solved by technology

However, for the fracture and collapse of both platforms, the steel plate cannot achieve a good fixation effect. At present, two ordinary steel plates are used to lock the fracture of the double platform separately, which is troublesome to operate and the locking effect is not ideal.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] as attached figure 1 , 2 The shown posterior locking plate for tibial double-plateau fractures includes an integrated plate body, a horizontal platform locking part 11, a vertical tibial body locking part 12 below the platform locking part 11, and a locking plate at the other end of the tibial body locking part 12. Reinforcing part 13, the junction of platform locking part 11 and tibial body locking part 12 is provided with transition connection part 14, and the width of both ends of platform locking part 11 is greater than the width of other places of platform locking part 11, makes both ends and platform The larger the contact area, the better the supporting effect. The transition connecting part 14 is a concave arc-shaped structure, which fits the tibial plateau and the tibial body transition to strengthen the supporting effect; eac...

Abstract

The invention belongs to the field of medical apparatuses and relates to a locking steel plate for fracture, in particular to a locking steel plate for posterior double tibial plateau fracture. The locking steel plate comprises a plate body; the plate body comprises a plateau locking part, a tibial body locking part and a locking reinforcing par, wherein the tibial body locking part is positioned below the plateau locking part, one end of the tibial body locking part is fixedly connected with the plateau locking part, and the locking reinforcing part is connected with the other end of the tibial body locking part; the plateau locking part, the tibial body locking part and the locking reinforcing part are respectively provided with a locking hole; the inner wall of each locking hole is provided with internal threads; the plate body and the tibia are locked by screws provided with external threads matched with the internal threads. The locking steel plate can be used for well supporting double tibial plateaus and can be matched with the shape of the bone on the rear side of the tibia so as to realize relatively firm attachment; the support effect is reinforced by means of the locking reinforcing part, the overall supporting and locking effects are better, and the operation is relatively convenient just by one integrated plate body.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to a locking steel plate for fractures, in particular to a rear locking steel plate for tibial double-plateau fractures. Background technique [0002] Tibial plateau fractures are one of the most common fractures in knee joint trauma. Intra-articular fractures require anatomical reduction and strong fixation. column fracture, and adopt the method of posterior support locking plate fixation, at the same time, a variety of support locking plates also emerge as the times require; for example, a posterolateral tibial plateau locking plate disclosed in the Chinese invention patent No. CN202505471, including Steel plate body, the steel plate body is composed of the lateral locking plate of the tibial plateau and the medial plate integrated with the lateral locking plate of the tibial plateau; there are locking holes on the lateral locking plate of the tibial plateau, and screw holes are provi...
