Abstract

The invention discloses an artificial clavicle coracoid joint capable of resetting and fixing an acromioclavicular joint. The artificial clavicle coracoid joint comprises an artificial clavicle acetabulum, a coracoid hook, an artificial clavicle pestle and a lifting threaded sleeve, wherein a hemispherical concave surface is arranged in the artificial clavicle acetabulum, and the lifting threaded sleeve and the artificial clavicle pestle are arranged in the hemispherical concave surface in an up-down overlapping manner. The lower portion of the artificial clavicle pestle is provided with a spherical convex face corresponding to the hemispherical concave face, the upper portion of the coracoid hook penetrates through the artificial clavicle pestle and extends into the lifting threaded sleeve, a threaded hole is formed in the lifting threaded sleeve, and the outer circle of the upper portion of the coracoid hook is provided with a first external thread corresponding to the threaded hole. By means of the mode, the artificial clavicle coracoid joint capable of resetting and fixing the acromioclavicular joint is specially designed with the artificial clavicle acetabulum and the artificial clavicle pestle, the acromioclavicular joint can be accurately reset by lifting the coracoid hook via rotation of the lifting threaded sleeve, the pestle-acetabulum-type artificial joint with the fixing and moving functions is formed, and thus flexible fixation of the acromioclavicular joint is formed.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an artificial clavicular coracoid joint that can reset and fix the acromioclavicular joint. Background technique [0002] For the dislocation of the acromioclavicular joint, the clavicular hook plate or the coracoid process hook can be used for fixation, and the upwardly displaced clavicle can be pressed down to fix the clavicle and the acromion or between the coracoid process, thereby correcting the dislocation. [0003] The existing clavicle hook plate and coracoid hook are usually an internal fixation device, which rigidly fixes the coracoid process and the clavicle, does not allow the movement of the acromioclavicular joint, and does not conform to the inherent physiological fretting law of the acromioclavicular joint. Complications such as posterior shoulder pain, limited joint mobility, and acromion osteolysis. The clavicle hook plate often needs to destroy a large part of t...
