Technical Field

The utility model relates to a spicule treatment field, concretely relates to fracture treatment connects skeleton with carbon fiber.

Background

Fracture is an important health problem affecting the labor capacity of the Chinese population. The common fracture treatment method is a bone-knitting operation, and the micro-motion of the local part of the fracture is eliminated through the pressurization and fixation of the fracture end and the reconstruction of an anatomical structure, so that the fracture can be healed for the first time without callus. In the process of fracture healing, the strong fixation can lead the joint muscles to perform full, active and painless activities as soon as possible without any external fixation, thereby preventing the occurrence of fracture diseases. In order to achieve strong internal fixation between the fractured ends, extensive exfoliation sometimes has to be performed to destroy the peripheral blood supply, resulting in osteoporosis of the fixed end, delayed or no healing of the fracture, and even infection, due to the pursuit of strong internal fixation, particularly crushing and complex fractures.

a carbon fiber-bonded framework comprises one or more horseshoe rings, spicules, spicule fixing pieces and horseshoe ring connecting pieces, wherein symmetrically distributed spicule fixing grooves and symmetrically distributed connecting piece mounting holes are formed in the annular plane of each horseshoe ring, the spicules are perpendicular to the bone penetrating through the human body along the axis of each horseshoe ring, and the two ends of each spicule are fixed on the surface of each horseshoe ring through the spicule fixing pieces; the adjacent horseshoe rings are connected through at least two horseshoe ring connecting pieces.

Furthermore, the spicule fixing groove is an arc-shaped waist-shaped groove, and one side of the waist-shaped groove, which is far away from the circle center of the horseshoe ring, is opened.

Furthermore, the horseshoe ring connecting piece is a rigid screw rod with external threads at two ends, or consists of two rigid screw rods connected by a universal joint, and the external threads are arranged at the end parts of the two rigid screw rods.

Furthermore, each end of the horseshoe ring connecting piece is fixedly connected with the horseshoe ring through a pair of nuts.

Furthermore, the spicule fixing piece is a bolt or a screw rod, one end of the screw rod is fixed on a spicule fixing groove of the horseshoe ring through a pair of nuts, and the spicule is fixedly arranged at the other end of the screw rod through the bolt.

Further, the horseshoe ring is made of carbon fiber materials.

Still further, the side of the horseshoe ring is provided with a plurality of lateral bone needle holes, and the axes of the bone needle holes are positioned in the plane of the horseshoe ring

After taking above technical scheme, the beneficial effects of the utility model are that: this technical scheme forms fixed support in the outside of fracture department through horseshoe ring and horseshoe ring connecting piece, and joint department can select to have universal joint to connect the horseshoe ring connecting piece and form flexible fixed stay, punctures the bone of the both sides of fracture department from the outside through the spicule to fix the spicule on the horseshoe ring through the spicule connecting piece and form fixedly, prevent the dislocation of bone. The bone-knitting frame is matched with different horseshoe ring connecting pieces and different bone needle fixing pieces, can realize the fixed treatment of the fracture of each part of the body, is convenient to combine and adjust, is stable in connection, only needs to be matched with a minimally-limited surgical operation, realizes minimally-invasive fracture treatment, and has a good treatment effect. Compared with the traditional single-arm external fixing frame, the fixing is reliable and effective. Because of adopting the carbon fiber material, the whole weight of the framework is lighter, the burden of the patient is lightened, and the rehabilitation of the patient is facilitated.
