これらの間に高周波を印加するものである。The bone fusion promoting device using the DC electrical stimulation method and the AC electrical stimulation method inserts two electrodes in the vicinity of the fractured part and allows current to flow between them. A pulsed electromagnetic field is irradiated from outside the body to the fracture to generate an induced current in the fracture. In addition, the bone fusion promoting device using the capacity induction method attaches two electrodes to the skin around the fractured portion with the fractured portion interposed therebetween,
A high frequency is applied between them.

う欠点がある。"Problems to be solved by the invention" By the way, among the conventional bone fusion promoting devices described above,
According to the DC stimulation method and the AC stimulation method, the DC electrode is inserted into the living body as described above, so that there is an advantage that the electric stimulation energy can be concentrated on the fracture. However, since the electrode is inserted into a living body, there is a disadvantage that physical pain is involved. On the other hand, the method using the pulsed electromagnetic field stimulation method and the capacitance induction method has an advantage that the burden on the patient is light because there is no need to insert an electrode into a living body. However, there is a disadvantage that it is difficult to efficiently concentrate the electrical stimulation energy on the fracture, and callus formation and bone fusion take a considerable period of time.
