The Hall plate 8 and the button switch 4 are connected to the control circuit board 6 through wires, and then connected to the device through the external connecting line 5, so as to realize signal transmission. The signals generated by the foot pedal switch are transmitted to the device through the control circuit board 6 and the external connecting line 5, and then displayed on the display screen of the device, so as to realize human-computer interface interaction and bring more convenience to operation.

[0030] The upper end of the foot pedal 3 is provided with a through groove 11, and a driving rotating rod 15 is embedded in the through groove 11. The top end of the driving rotating rod 15 is fixedly connected with a control plate 9, the top end of the control plate 9 is connected with a positioning foot cover 10, and a non-slip pad is laid on the upper surface of the control plate 9. The positioning foot cover 10 is higher than the top end of the control plate 9, and the feet of medical staff can be fixed by the positioning foot cover 10, which plays a limiting role and is more convenient to operate.

[0031] The upper end of the base 1 is fixedly connected with a fixed bending rod 16, the top end of the fixed bending rod 16 is provided with a second bevel gear 14, the fixed bending rod 16 is embedded in the center shaft of the second bevel gear 14, the second bevel gear 14 and the fixed bending rod 16 are rotatably connected, the center shaft of the second bevel gear 14 is embedded with the driving rotating rod 15, and the driving rotating rod 15 and the second bevel gear 14 are fixedly connected. The rising and falling of the foot pedal 3 is controlled by the distance between the magnet 7 and the Hall plate 8 to realize the control of the device and human-computer interaction. When the angle of the foot pedal 3 is controlled, the medical staff needs to step into the inside of the positioning foot cover 10, and then rotate the ankle to make the positioning foot cover 10 and the control plate 9 rotate around the driving rotating rod 15 as the shaft. When the driving rotating rod 15 rotates, the first bevel gear 13 meshing with the driving rotating rod 15 rotates, and when the first bevel gear 13 rotates, the shaft rod 12 rotates, and when the shaft rod 12 rotates, the shaft rod 12 drives the foot pedal 3 to deflect the angle. After the angle of the foot pedal 3 deflects, the rising and falling of the foot pedal 3 is realized. The medical staff embeds the feet in the inside of the positioning foot cover 10, and the positioning foot cover 10 provides good support for the feet. Therefore, the control of the positioning foot cover 10 is more convenient. The difference between standing and sitting pedal stepping is whether the legs are supported. When standing, the legs have no external support, and during the pedal stepping process, the amplitude of the foot depression needs to overcome the weight of the body, and the control precision is relatively poor. The stability of the pedal stepping is also relatively poor. Therefore, the positioning foot cover 10 provides support for the feet, so that the control is more stable.
