The shock wave therapy machine can be divided into the following four types according to the way the shock wave is generated:
1. Liquid-electric type: The electrode is discharged in water or other liquid, and the energy is concentrated by the reflector to the second focus. Now such equipment has been produced less;
2, pneumatic ballistic type: the use of vibrators in the cavity to move at high speed to generate vibration, coupled into the human body through the gun probe (principles with the same nail gun, cement gun), such equipment generated 3, mechanical waves do not have focusing characteristics, also known as a scattering shock wave treatment device;
4, electromagnetic type: high-voltage pulse strong current through the coil to generate a magnetic field, to promote the diaphragm movement to generate shock waves, to achieve focus, flat shot, or scattering into the human body, the corresponding treatment;
Piezoelectric ceramics: Piezoelectric crystal materials are used as transducers, and such equipment is not yet available.
Treatment characteristics
Shock wave treatment of strained disease treatment process is simple, non-invasive treatment, less damage to patients, shock wave treatment equipment analgesic effect is more obvious than other physiotherapy equipment, especially for the treatment of frozen shoulder.
