An Angle-Adjustable Sternoclavicular Joint Leaping Plate

Abstract

The invention discloses an angle-adjustable sternoclavicular joint spanning steel plate. The technical solution includes a fixed steel plate, two ends of the fixed steel plate are respectively provided with clavicle fixing parts, the middle part of the fixed steel plate is provided with a connecting part, and the connecting part is A connecting piece is provided on the clavicle fixing part, and a clavicle fixing hole is arranged on the clavicle fixing part. The clavicle fixing hole is provided with a plurality of them and is arranged at equal distances along the length direction of the clavicle fixing part. The connecting piece includes a communication hole, a rotating rod and an active slot And the connecting rod, the communication hole and the rotating rod are all extended along the thickness direction of the connecting part. During the rotation of the rotating rod, the connecting rod swings up and down in the movable groove, and there is space between the connecting part and the two clavicle fixing parts for the clavicle fixing part to swing up and down. There is a rotating handle in the communication hole, a limited rotation cap is set in the communication hole, and the height dimension of the limited rotation cap is not higher than the depth dimension of the communication hole. Adjustable.

Description

technical field [0001] The invention relates to a medical device, more specifically, it relates to a sternoclavicular joint spanning steel plate with adjustable angle. Background technique [0002] Traumatic sternoclavicular joint dislocation is relatively rare in clinical practice. Among the 1603 patients with shoulder girdle injuries summarized by Gave, sternoclavicular joint dislocation accounted for about 3% of the total. With the modernization of production and delivery tools, traumatic sternoclavicular joint dislocations have gradually increased in recent years. [0003] Due to the characteristics of the anatomical structure of the sternoclavicular joint, the dislocated sternoclavicular joint is not easy to stabilize, it is easy to dislocate again after reduction, and it is difficult to maintain external fixation. The best treatment option for such patients is internal fixation after reduction. The traditional plate fixation has the following problems: 1. There are m...

Problems solved by technology

The traditional plate fixation has the following problems: 1. There are many important blood vessels and organs in the sternoclavicular joint; 2. It is difficult to provide enough bone tissue for fixation at the proximal end of the sternum and clavicle; 3. The plate itself needs a suitable Angle, when the angle is too large or too small, the surgeon usually needs to bend the steel plate with something (it is inconvenient to grasp the angle). If the steel plate with an inappropriate angle is used directly, it will easily cause the steel plate to not be firmly attached, the steel plate to warp, etc., which is extremely serious.
