Description

Technical Field

[0001] The utility model relates to a bone fracture plate, in particular to a micro-power pressurized locking bone fracture plate, belonging to the technical field of medical equipment. Background Art

[0002] Bone plates are perforated plate-shaped internal fixation devices for fractures. They are often used in conjunction with bone screws or bone wires in clinical practice. They are divided into two categories: ordinary bone plates and compression bone plates. They can be made into strips, Y-shapes, L-shapes, T-shapes, etc. according to different uses.

[0003] However, the rigidity of existing compression locking plates is not ideal. Insufficient rigidity may not provide sufficient support, resulting in ineffective fixation of the fracture, prolonged healing time, and even increased risk of re-displacement. Due to insufficient rigidity of the plate, the fracture may not be able to obtain ideal stability, affecting the healing process and prolonging the healing time. During activities, the plate with insufficient rigidity may not be able to effectively share the pressure at the fracture site, causing pain and discomfort.

[0004] Therefore, a micro-dynamic compression locking bone plate is proposed. Utility Model Content
