Special-shaped rib surrounding bone fracture plate and use method thereof

Abstract

The invention relates to a special-shaped rib surrounding bone fracture plate. The bone fracture plate is characterized by being provided with a main trunk, wherein 2-6 pairs of symmetric surrounding arms are arranged on the main trunk; the main trunk is arc-shaped; the 2-6 pairs of surrounding arms are uniformly arranged at the two ends of the main trunk; one end of the main trunk is provided with large-diameter surrounding arms, and the other end of the main trunk is provided with small-diameter surrounding arms; the diameter of the large-diameter surrounding arms is greater than that of the small-diameter surrounding arms; the entire bone fracture plate is conical. During use, a proper product can be selected according to the fracture shape of a rib, one larger-diameter segment is used for fixing one thicker segment of the rib, the other end is used for fixing one thinner segment of the rib, and two or four pairs of surrounding arms can effectively fix. For short-distance rib bone fracture, two or four pairs of the special-shaped rib surrounding bone fracture plates are adopted; for longer-distance rib bone fracture, six pairs of the special-shaped rib surrounding bone fracture plates are adopted. By adopting the (conical) special-shaped rib surrounding bone fracture plate, the rib fracture can be well fixed. Since dynamic surrounding and pressurized fixing are adopted, so that bone growth is facilitated, and the rehabilitation period is shortened. A good fixing effect is achieved, and the problem of difficulty in operation is solved.

Description

[0001] technical field [0002] The invention relates to the technical field of medical devices, in particular to an internal fixation device for fixing rib fractures in medical operations, and in particular to a special-shaped rib embracing bone plate. Background technique [0003] At present, the clinical treatment of ribs and surgical treatment of rib fractures require rib internal fixation devices to help reduce and fix them. The previous rib internal fixation devices are only suitable for general rib fractures, and it is difficult to deal with the following types of rib fractures: [0004] 1 one multi-segment fracture, or comminuted rib fracture; [0005] 2 Rib defect fractures caused by surgery; [0006] 3 Ribs with varying thickness, or ribs near the end of the spine. [0007] General rib fixation methods include: Kirschner wires, reconstruction plates, anatomical plates, locking plates, and absorbable screws. The Kirschner wire is easy to operate, but it is easy...

AI Technical Summary

Problems solved by technology

[0013] The purpose of the present invention is to provide an improved special-shaped rib embracing bone plate, which can overcome the fracture of a multi-segmented, crushed, defective or part of a special-shaped rib with a large change in the thickness of a single rib and the fracture near the end of the spine in the prior art. The left and right arc shaped ribs cannot well achieve some deficiencies in fracture reduction and fixation
