Divergent and focused shock waves can be used to treat superficial tissues within 2 cm.
Case Details
The transmission form of shock waves: can be divided into focusing type, diverging type, etc.
The wave sources of shock waves have the following forms:
① pneumatic ballistic shock wave source;
② piezoelectric crystal shock wave source;
③ electromagnetic shock wave source;
④ liquid-electric shock wave source.
Among them, the focus of the liquid-electric type is like an ellipsoid, the focus of the electromagnetic shock wave is too narrow and long, and the focus of the piezoelectric shock wave is smaller and more targeted. It is the most accurate of the three focused shock waves.
The biological therapeutic effects of shock waves include:
① tissue damage repair and reconstruction;
② tissue adhesion loosening effect;
③ vascular dilation and vascular regeneration effect;
④ analgesia and nerve endings blocking effect;
⑤ high-density tissue lysis effect;
⑥ inflammation and infection control effect.
The difference between the principles of focused and divergent shock wave generation
Divergent shock wave mainly generates energy through pneumatic ballistics. The energy focus point is on the skin surface and enters the tissue in a divergent form to treat superficial tissue diseases. The advantages of divergent shock waves are simple operation and relative safety, while the disadvantages are energy divergence, poor precision targeting, and shallow penetration.
Focused shock waves mainly generate energy through piezoelectric, hydraulic, and electromagnetic focusing. They have fast propagation speed, low energy loss, and can treat deep lesions. The advantages of focused shock waves are large energy, strong targeting, and deep penetration. The disadvantages are that they require precise positioning and high operation requirements.
Piezoelectric focused shock waves overcome the technical bottlenecks of traditional focused shock waves, successfully improve focusing accuracy, greatly extend the treatment service life, and reduce the working noise of the machine. It is undoubtedly the development direction of focused shock wave technology and a new choice for clinical treatment.
Difference in scope of application
First, both can be used to treat superficial tissues within 2 cm.
Divergent type is more suitable for pain in superficial tissues and muscle groups with a larger area, and is suitable for mobile diseases. For example, tennis elbow, tenosynovitis, Achilles tendonitis, muscle spasms caused by stroke, relaxation of the overall muscles of the neck and shoulders, and relaxation of the lumbar and back fascial chains.
Focused shock waves have advantages for bone diseases, deep layers, and bone and muscle diseases with clear pain points, such as calcific supraspinatus tendinitis, piriformis syndrome, deep fascial pain points, nonunion and delayed healing, early femoral head necrosis, and other diseases.
