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
The present invention relates to technical field of medical instruments, particularly to a kind of breastbone external fixer.
Background technology
Caused by fracture of sternum is often severe thoracic injury complicated, directly act on sternal region or extruding mainly due to powerful violence
Caused, how because the deceleration wound of traffic accident or direct collision injury cause, also can directly be hit by extruding and blunt and cause, account for thoracic trauma
5% about, mostly caused by traffic accident.Fracture mostly occurs in the body of breastbone, and majority is the bone of non-displacement, transecting type
Folding.Wherein fractured with sternal body most common, account for 76.5%, secondly for manubrium fracture, account for 9.0%, manubrium, body have a common boundary
Place's fracture accounts for 8.5%, is often associated with fracture of rib, haemopneumothorax, limbs fracture etc..
Because the stability of the front wall of the chest is affected after fracture of sternum, thorax leads to the broken ends of fractured bone cannot brake with respiratory movement, and
Produce violent local pain, lead to breathing limited, airway secretions increase, cause restricted obstructive ventilatory difficult and lung
The generation of complication, and fracture site is unstable, can aggravate broken ends of fractured bone bleeding, or even may result in increasing of associated injury.Therefore, emergency treatment
Early stage carries out local and fixes, and pain and fracture end displacement is effectively mitigated or eliminated, is the key link of fracture of sternum treatment
Breastbone is cancellous bone, the multigroup ligament of attachment, muscle, and obtains the support of costal cartilage, clavicle, and Peripheral blood supplies to enrich,
Self-healing ability is very strong, and fracture of sternum is stable mostly, therefore, though for the stable breastbone bone of no obvious displacement or displacement
Folding, typically without operation intervention, only need to take lie up, pain relieving braking, pectoral girdle are fixed, are encouraged expectoration, prevent infection etc. from controlling
Treat, and prognosis bona.And the obvious displacement for breastbone, cause thorax unstable, even result in nonunion, breathing occurs tired
Difficult person need to select operative treatment as early as possible, but also needs local to take fixation for treatment before surgery, to mitigate the pain of patient, stable disease
Feelings.The expectant treatment of fracture of sternum mainly selects effective External fixation at present, but there is no preferably outer fixation to control at present
Treatment method, conventional method has fracture site sandbag pressing, using pectoral girdle pressurized fixation for treatment, but all exists outer fixing easy
Displacement, fixing uncertain, limit movement of thorax, the deficiency such as impact respiratory function；Also have fixing outside the chest of employing " BABAKA "
Device treat, equally exist in-convenience in use, impact sleep the shortcomings of.
Content of the invention
It is an object of the invention to provide a kind of breastbone external fixer, fracture of sternum effectively can be fixed, fixing
Do not shift, effect is good, the restriction to movement of thorax can be mitigated it is ensured that respiratory function is normal, reduce pulmonary complication, prevent breastbone
The generation of hemotoncus and progress afterwards, improves patient comfort.
The above-mentioned technical purpose of the present invention technical scheme is that：Breastbone external fixer, including
Left fixed plate, right fixed plate, the left connect band being fixed in described left fixed plate and be fixed on the sum in described right fixed plate
The right connect band of described left connect band cooperation；Also include the air bag being located between described left fixed plate and described right fixed plate
And the manual inflatable ball with described air bag connection.
Preferably, described air bag includes frame, multiple strip air bags being located in described frame and multiple described
Strip air bag connect distributor and be located on described distributor be used for control enter described strip air bag compressed air amount
