External sternal fixation device

Abstract

The invention discloses an external fixing device for a breastbone. The external fixing device comprises a left fixing plate, a right fixing plate, a left connection band fixed to the left fixing plate and a right connection band fixed to the right fixing plate and matched with the left connection band. The external fixing device further comprises an inflation air bag arranged between the left fixing plate and the right fixing plate and a manual inflation ball connected with the inflation air bag. According to the external fixing device for the breastbone, thoracic bones can be effectively fixed, the fixation effect is good, movements of the thorax cannot be limited, it is guaranteed that the breath function is normal, pulmonary complications can be reduced, substernal hematomas can be prevented from occurring and developing and the comfort of patients is improved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a sternal external fixation device. Background technique [0002] Sternal fractures are often caused by severe thoracic trauma, mainly due to strong violence directly acting on the sternal area or extrusion, mostly due to deceleration injuries or direct impact injuries in car accidents, or direct impacts from extrusion and blunt instruments. Accounting for about 5% of thoracic trauma, mostly caused by traffic accidents. Fractures mostly occur in the body of the sternum, and most are non-displaced, transverse fractures. Among them, fractures of the sternal body are the most common, accounting for about 76.5%, followed by fractures of the sternal manubrium, accounting for about 9.0%, and fractures at the junction of the sternal manubrium and body, accounting for about 8.5%, often accompanied by rib fractures, pneumothorax, and limb fractures. [0003] After the fractu...

AI Technical Summary

Problems solved by technology

At present, the conservative treatment of sternal fractures is mainly to choose effective external fixation treatment, but there is no ideal external fixation treatment method at present. The traditional methods include compressing the fracture site with sandbags and local compression and fixation with chest straps. Displacement, inaccurate fixation, restriction of thoracic movement, impact on respiratory function and other deficiencies; there are also "back and back" chest external fixation devices for treatment, which also have disadvantages such as inconvenient use and affecting sleep
