Abstract

The invention discloses a clavicle fracture percutaneous reduction distraction pressurization fixing device which comprises a reduction fixing plate arranged on the body surface and matched with the physiological curvature of a clavicle, an arc-shaped sliding groove is formed in the reduction fixing plate, a plurality of screw assemblies are connected in the arc-shaped sliding groove, and each screw assembly comprises a screw body and a locking nut. The screw body comprises an upper screw rod part, a lower screw rod part and a step part located between the upper screw rod part and the lower screw rod part, and the locking nut is connected to the upper screw rod part in a matched and screwed mode and matched with the step part to lock the screw body to the reset fixing plate. An expanding, pressurizing and fine-adjusting mechanism which is positioned outside the body and is adjustable in length is connected between the two adjacent screw assemblies close to the fracture end. When the device is used, only several small incisions need to be formed in the two ends of the fracture of the clavicle, and several screw assemblies locked into the clavicle are placed in the small incisions. According to the instrument, minimally invasive surgery is well achieved, periosteum stripping can be reduced through percutaneous body surface external fixation, blood supply is protected, and fracture nonunion is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a percutaneous reduction, distraction, pressurization and fixation device for clavicle fractures. Background technique [0002] The clavicle is the first long tubular bone to ossify in the human body. During development, it forms two physiological curves, the outer section is kyphosis, and the inner section is lordotic, resembling a horizontal S lying in front of the top of the thorax. The outer 1 / 3 is flat (the front is flatter), and the inner 1 / 3 is approximately triangular (the upper part is flatter). It lies subcutaneously along its full length, forms a sternoclavicular joint proximally with the manubrium sternum, and forms acromioclavicular joint distally with the acromion. Is the only bony structure that connects the shoulder girdle to the sternum. Clavicle fracture (fracture of the clavicle) occurs in adolescents and children, and the incidence rate accounts for ...
