Novel dissection locking steel plate for sternoclavicular joint and matched barrier plate

Abstract

The invention discloses a novel dissection locking steel plate for the sternoclavicular joint and a matched barrier plate and relates to the field of medical apparatus and instruments. The novel dissection locking steel plate is used for solving the technical problems of complex fixing mode, large operation risk and the like in fracture dislocation of the sternoclavicular joint in the prior art. The steel plate comprises a breastbone handle plate part, a collarbone end plate part, a sternoclavicular joint plate part and the matched barrier plate; the breastbone handle plate part comprises a breastbone handle front plate, a breastbone handle back plate and an arc breastbone incisura hook plate which connects with the breastbone handle front plate and the breastbone handle back plate, the breastbone handle plate part is in a U shape, and the matched barrier plate comprises a barrier plate head part, a barrier plate body part and a barrier plate tail part; the barrier plate head part is connected with the barrier plate tail part through the barrier plate body part, the barrier plate head part is arranged to be in a groove shape, and the barrier plate tail part is arranged to be in a handle shape. The novel dissection locking steel plate for the sternoclavicular joint accords with anatomy characteristics of the sternoclavicular joint of Chinese, is reasonable in mechanical property, is easy, convenient and safe to operate during operation, is fixed reliably, is low in risk, allows a patient to conduct rehabilitation function exercising after operation in the early stage, and restores the function of the shoulder girdle.

Description

technical field [0001] The invention relates to the technical field of medical devices, and more specifically relates to a novel anatomical locking steel plate for a sternoclavicular joint and a matching blocking plate. Background technique [0002] Dislocation of the sternoclavicular joint includes anterior dislocation in which the inner end of the clavicle protrudes upward and forward, and posterior dislocation in which the inner end of the clavicle protrudes downward and backward or the clavicular head slides posteriorly and inwardly toward the manubrium of the sternum. The common cause of sternoclavicular joint dislocation is high-energy injury. Sternoclavicular joint dislocation and surrounding fractures are rare in clinical practice. Most of them are high-energy direct or indirect violence transmitted from the side of the shoulder or the abducted upper arm along the clavicle to the chest. Injury to the clavicle joint. Depending on the magnitude of the force and the po...
