A biopsy driver includes a housing, a battery power source, a motor, a trigger, and a control circuit. The control circuit has a flip-flop switch circuit, a resistance network circuit, and a pulse width modulation circuit. The flip-flop switch circuit has an off state and an on state. The resistive network circuit is coupled to an input of the pulse width modulation circuit. The pulse width modulation circuit is configured to generate a variable pulse width signal to control a rotational speed of the motor. When the flip-flop switch circuit is in an on state, the flip-flop switch circuit is configured to connect a negative terminal of the battery power supply to chassis ground and select a resistance value from the resistance network circuit to select a desired duty cycle of the variable pulse width signal generated by the pulse width modulation circuit. 一种活检驱动器，包括壳体、电池电源、马达、触发器和控制电路。控制电路具有触发器开关电路、电阻网络电路和脉宽调制电路。触发器开关电路具有关闭状态和开启状态。电阻网络电路耦合到脉宽调制电路的输入端。脉宽调制电路被配置为生成可变脉冲宽度信号以控制马达的转速。当触发器开关电路处于开启状态时，触发器开关电路被配置为：将电池
