故障现象一：碎石治疗时，不时有连炮现象。分析检修：电极端连续放炮，与呼吸脉冲发生电路、高压触发电路有关；因为一次放炮的形成，先是呼吸脉冲电路产生脉冲，使触发电路光耦导通亮一下，可控硅导通，通过充放电，产生触发电压，使高压开关导通，而形成一次放炮。观察光耦 Symptom 1: The lithotripsy treatment, from time to time even the gun phenomenon. Analytical overhaul: Continuous firing of the electrode tip is related to the respiration pulse generation circuit and the high-voltage trigger circuit. Because of the formation of a shot, the first pulse is generated by the respiration pulse circuit, so that the trigger circuit optocoupler is turned on and the thyristor is turned on. Discharge, generate a trigger voltage, make the high-voltage switch conduction, and the formation of a shot. Observing the optocoupler
