Medical instrument motor driving circuit

The invention relates to the medical field, in particular to a medical instrument motor driving circuit. The technical problem of the invention is to provide a medical instrument motor drive circuit capable of avoiding instrument damage. According to the technical scheme, the medical instrument motor drive circuit comprises an MCU, a first optical coupler isolation circuit, a second optical coupler isolation circuit and the like. The input end of the first optical coupler isolation circuit and the input end of the second optical coupler isolation circuit are both connected with the MCU. According to the invention, through the first optical coupler isolation circuit and the second optical coupler isolation circuit, an isolation effect can be achieved, the anti-interference capability is improved, the direct current motor is prevented from being interfered by other signals, instrument damage is avoided, and through the effect of the second LED indicating lamp and the first LED indicating lamp, people can conven
