Since the hammer of the hammer crusher is suspended by the hinge on the hammer plate, the correct selection of the hammer head quality has a great effect on the crushing efficiency and energy consumption. If the quality of the hammer is chosen too small, it may not meet the requirement to break the material once hammering. If the selection is too large, the useless power consumption is too large. Therefore, the mass of the hammer must meet the hammering once to break the material and minimize the useless power consumption. At the same time, the hammer must not be overturned backwards. According to the principle of conservation of momentum, after the hammer hits the material, a speed loss will inevitably occur. The impact crusher needs to be improved due to structural and mechanical reasons, and the allowable speed loss of the hammer strike material varies with the size of the crusher.
Rib Locking Plate System is suitable for the fixation of rib fractures,which includes rib locking plate,rib locking screw and rib plate.
Ribs are structures throughout the thoracic cavity that protect vital organs such as the lungs, heart, and liver.The human body has 12 symmetrical pairs of ribs.
Where did the fracture occur?
Rib fractures are more common in adults. Fractures of one or more ribs may occur, and multiple fractures of the same rib may occur. The first to third ribs are shorter, protected by the scapula, clavicle, and upper arm, and are generally less prone to injury, while the floating ribs are more elastic and less prone to fracture. Fractures usually occur in four to seven ribs.
What is the cause of the fracture?
1. Direct violence. Fractures occur where violence directly affects them. They are usually cross-sectional or comminuted. Fracture fragments are often displaced inward and easily penetrate into the lungs, causing pneumothorax and hemothorax.
2. Indirect violence, chest is squeezed back and forth, fractures often occur near the axillary midline. The end of the fracture protruded outwards, which easily punctured the skin and caused open fractures, such as collapse or improper exertion during external cardiac massage. There have also been cases of posterior rib fractures due to violent blows to the anterior chest, or anterior rib fractures due to blows to the posterior chest. Most of the fractures were oblique.
3. Mix violence and others.
What type does fracture have?
1. Simple fracture
2. Incomplete fracture: mostly crack or green branch fracture
3. Complete fracture: most of them are transverse, oblique or comminuted
4. Multiple fractures: one bone and two fractures, multiple rib fractures
5. Open fracture: mostly caused by indirect violence or firearm injury
What are the complications of sternal fracture?
1. Abnormal breathing 2. Pneumothorax 3. Hemothorax
