This series of therapeutic instruments are medical devices developed by our company for fracture trauma treatment. They have detumescence and analgesia effect to the fracture trauma parts, moreover, they can stimulate the rapid forming of callus on the fracture parts and accelerate the bone healing. They can be widely used in clinical treatment for femur, tibia, fibula, femur neck, patella, ulna, radius and other fracture trauma.  They are convenient, safe, and non-invasive, etc, and wins a good reputation among the medical workers and the patients. They are advanced and regular standby medical devices fororthopedics and traumatology department, rehabilitation department, physiotherapy department, and Chinese traditional medicine department and so on.

The therapeutic instrument is based on microcomputer treatment, and combines three physical factors: magnetic, bioelectricity and heat, to carry out adjuvant treatment.

It has neither special requirement for working place nor interference with other kinds of medical devices. It doesn’t ask for any special care after starting up. It is stable, safe and easy to operate.

1. Principle of pulsed magnetic therapy: based on magnetic biology and clinical physical medicine, and designed according to the reasonable data filtered from our experimental research, adopting magnetic stimulation technique and using microelectronic technique to emerge the pulsed magnetic field which adapts to human bio-electricity activity, and output FM or AM, focusing or paramagnetic alternating electromagnetic fields through special magnetic therapeutic head to penetrate the plywood, plaster or other fixtures and clothes outside the patient’s fracture or sprain part, and act on bone, muscle, and soft tissues, etc., and then produce a series of magneto biological effect to achieve the therapy for fracture parts and soft tissue injury.

2. Therapeutic principle of electric stimulation: the main principle is to draw two groups of sinusoidal intermediate frequency currents into the fracture parts, and form the disturbance field at the fracture end, which produces a kind of rotational changeable healing current. This current can stimulate the growth of the bone cells, promote calcium deposition, improve blood and lymph circulation, and guide and nourish vessel’s growth.
