[0073] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein.

[0074] Figure 1 This is a schematic diagram of the signal output control interface of a surgical system provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the signal output control interface of another surgical system provided in an embodiment of the present invention. See also... Figures 1-2 The signal output control interface of the surgical system includes: a signal acquisition circuit 1, a signal control circuit 2, a signal indication circuit 3, and an indicator panel 4. The signal acquisition circuit 1 is used to acquire the electrosurgical foot pedal signal and output the electrosurgical control signal. The signal acquisition circuit 1 is also used to acquire the ultrasonic scalpel foot pedal signal and output the ultrasonic scalpel control signal. The signal control circuit 2 is electrically connected to the signal acquisition circuit 1 and is used to output the electrosurgical indicator light control signal according to the electrosurgical control signal. The signal control circuit 2 is also used to output the ultrasonic scalpel indicator light control signal according to the ultrasonic scalpel control signal. The signal indication circuit 3 includes a first signal indication unit 30 and a second signal indication unit 31. The first signal indication unit 30 is connected to the signal acquisition circuit 1. Control circuit 2 is electrically connected. First signal indicator unit 30 outputs an electrosurgical indicator light ignition signal based on the electrosurgical indicator light control signal. Second signal indicator unit 31 outputs an ultrasonic scalpel indicator light ignition signal based on the ultrasonic scalpel indicator light control signal. Indicator panel 4 is electrically connected to first signal indicator unit 30 and controls the electrosurgical indicator light to illuminate based on the electrosurgical indicator light ignition signal. Indicator panel 4 is also electrically connected to second signal indicator unit 31 and controls the ultrasonic scalpel indicator light to illuminate based on the ultrasonic scalpel indicator light ignition signal. An energy device is used to perform electrosurgical ablation when the electrosurgical indicator light is illuminated, and to perform ultrasonic ablation when the ultrasonic scalpel indicator light is illuminated.

[0075] The energy devices include an electrosurgical unit and an ultrasonic scalpel. The electrosurgical unit is divided into a monopolar electrosurgical unit and a bipolar electrosurgical unit. The signal acquisition circuit 1 is electrically connected to multiple foot switches. The foot pedal signals for the electrosurgical unit and the ultrasonic scalpel are generated by their respective foot switches. In actual operation, the electrosurgical unit and the ultrasonic scalpel may be working simultaneously.

[0076] Signal acquisition circuit 1 acquires the electrosurgical foot pedal signal or ultrasonic scalpel foot pedal signal and transmits it to signal control circuit 2. Signal control circuit 2 outputs indicator light control signals for different energy devices according to the electrosurgical foot pedal signal or ultrasonic scalpel foot pedal signal. The first signal indication unit 30 outputs an electrosurgical indicator light ignition signal according to the electrosurgical indicator light control signal (i.e., a high-level signal). If the electrosurgical indicator light is lit, it indicates that there is no fault in the wiring between signal acquisition circuit 1, signal control circuit 2, and the first signal indication unit 30, and the energy output of the electrosurgical is normal. If the electrosurgical indicator light is not lit, it indicates that there is a fault in the wiring between signal acquisition circuit 1, signal control circuit 2, and the first signal indication unit 30, and the energy output of the electrosurgical is normal.

[0077] Similarly, the second signal indicator unit 31 outputs an ultrasonic scalpel indicator light illumination signal based on the ultrasonic scalpel indicator light control signal (i.e., a high-level signal). If the ultrasonic scalpel indicator light illuminates, it indicates that there is no fault in the wiring between the signal acquisition circuit 1, signal control circuit 2, and second signal indicator unit 31, and that the ultrasonic scalpel's energy output is normal. If the ultrasonic scalpel indicator light does not illuminate, it indicates a fault in the wiring between the signal acquisition circuit 1, signal control circuit 2, and second signal indicator unit 31, and that there is a fault in the wiring between the signal acquisition circuit 1, signal control circuit 2, and second signal indicator unit 31. (That is, the signal indicator circuit 3 can indicate the energy output status of the energy device and determine the fault node of the surgical system's signal output control interface through the indicator circuit). The indicator panel 4 is used for external indicator light prompts and energy device connection.

[0078] When the electrosurgical indicator light is on, the electrosurgical unit performs electrical ablation, indicating that the electrosurgical unit is not malfunctioning. When the electrosurgical indicator light is on, the electrosurgical unit does not perform ablation, indicating that the electrosurgical unit is malfunctioning. When the ultrasonic scalpel indicator light is on, the ultrasonic scalpel performs ultrasonic ablation, indicating that the ultrasonic scalpel is not malfunctioning. When the ultrasonic scalpel indicator light is on, the ultrasonic scalpel does not perform ultrasonic ablation, indicating that the ultrasonic scalpel is malfunctioning.

[0079] In this embodiment of the invention, the signal acquisition circuit 1 is used to acquire the electrosurgical foot pedal signal or the ultrasonic scalpel foot pedal signal, and outputs the electrosurgical control signal or the ultrasonic scalpel control signal accordingly. The signal control circuit 2 is used to output the electrosurgical indicator light control signal and the ultrasonic scalpel indicator light control signal accordingly based on the electrosurgical control signal or the ultrasonic scalpel control signal. The first signal indication unit 30 is used to output the electrosurgical indicator light illuminating signal according to the electrosurgical indicator light control signal. The second signal indication unit 31 is used to output the ultrasonic scalpel indicator light illuminating signal according to the ultrasonic scalpel indicator light control signal. The indicator light panel 4 is used to control the electrosurgical indicator light and the ultrasonic scalpel indicator light to illuminate accordingly based on the electrosurgical indicator light illuminating signal or the ultrasonic scalpel indicator light illuminating signal. If the ultrasonic scalpel indicator light is on, it confirms that there is no fault in the connections between signal acquisition circuit 1, signal control circuit 2, and signal indication circuit 3, as well as between these circuits. Conversely, if the electrosurgical or ultrasonic scalpel indicator light is off, it confirms a fault in the connections between these circuits. If the electrosurgical or ultrasonic scalpel indicator light is on, and the corresponding energy device is working, then the energy device is not malfunctioning. If the electrosurgical or ultrasonic scalpel indicator light is on, but the corresponding energy device is not working, then the energy device is malfunctioning. This invention can intuitively display the real-time output status of the energy device and quickly identify the fault point, thus completing surgical operations more efficiently and reducing surgical risks for patients.

[0080] See Figures 1-2 Optionally, based on the above embodiments, the electrosurgical foot pedal signal includes an electrocuting foot pedal signal and an electrocoagulation foot pedal signal; signal acquisition circuit 1 is used to acquire the electrocuting foot pedal signal and output an electrocuting control signal; signal acquisition circuit 1 is used to acquire the electrocoagulation foot pedal signal and output an electrocoagulation control signal; signal control circuit 2 is electrically connected to signal acquisition circuit 1, and signal control circuit 2 is used to output an electrocuting indicator light control signal according to the electrocuting control signal; signal control circuit 2 is used to output an electrocoagulation indicator light control signal according to the electrocoagulation control signal; the first signal indication unit 30 is electrically connected to signal control circuit 2.

[0081] Among them, electro-cutting and electro-coagulation are two modes of monopolar electrosurgical knife, while bipolar electrosurgical knife only has an electro-coagulation mode. The energy output status of electro-cutting and electro-coagulation of monopolar electrosurgical knife and electro-coagulation of bipolar electrosurgical knife are indicated by the electrosurgical knife indicator light. The electro-cutting indicator light and the electro-coagulation indicator light belong to the same indicator light. The electro-cutting foot pedal signal and the electro-coagulation foot pedal signal are generated by the corresponding foot pedal switch.

[0082] Specifically, the first signal indication unit 30 outputs corresponding electric cutting indicator light and electric coagulation indicator light illumination signals according to the electric cutting indicator light control signal or the electric coagulation indicator light control signal. The indicator panel 4 controls the electric cutting indicator light to illuminate according to the electric cutting indicator light illumination signal, and the indicator panel 4 controls the electric coagulation indicator light to illuminate according to the electric coagulation indicator light illumination signal. If the electric cutting indicator light is on, it can be determined that the electric cutting energy output is normal and there is no fault in the electric cutting energy output line. If the electric coagulation indicator light is on, it can be determined that the electric coagulation energy output is normal and there is no fault in the electric coagulation energy output line. Conversely, if the electric cutting indicator light or the electric coagulation indicator light is off, it can be determined that there is a fault in the electric cutting energy output line or the electric coagulation energy output line.

[0083] If the electro-cutting indicator light is on and the electro-cutting knife is performing electro-cutting, or if the electro-coating indicator light is on and the electro-coating knife is performing electro-coating, then the electro-cutting knife is not malfunctioning. Conversely, if the electro-cutting indicator light is on and the electro-cutting knife is not performing electro-cutting, or if the electro-coating indicator light is on and the electro-coating knife is not performing electro-coating, then the electro-cutting knife is malfunctioning.

[0084] In this embodiment of the invention, such a setting can intuitively display the real-time energy output status of electrocautery and electrocoagulation, quickly identify fault nodes in the energy output circuit of electrocautery or electrocoagulation and electrocautery failure, shorten electrocautery repair time, and reduce the surgical risk for patients.

The first energy indicator light is turned on according to the control signal of the first energy indicator light; the second signal indicator unit 31 is used to turn on the second energy indicator light according to the control signal of the second energy indicator light; the indicator panel 4 is electrically connected to the second signal indicator unit 31, and the indicator panel 4 is used to control the first energy indicator light to turn on according to the first energy indicator light turning on signal; the indicator panel 4 is used to control the second energy indicator light to turn on according to the second energy indicator light turning on signal; when the first energy indicator light is turned on, the energy instrument performs ultrasonic ablation with the first energy; when the second energy indicator light is turned on, the energy instrument performs ultrasonic ablation with the second energy, the second energy being greater than or equal to the first energy.

[0086] The first energy mode and the second energy mode are the two modes of the ultrasonic scalpel. When either the first energy mode or the second energy mode is enabled, the ultrasonic scalpel indicator light will show energy output. The first energy indicator light and the second energy indicator light are the same type of indicator light. The first energy foot pedal signal and the second energy foot pedal signal are generated by corresponding foot switches.

[0087] The second signal indication unit 31 outputs a first energy indicator light ignition signal according to the first energy indicator light control signal. The indicator light panel 4 controls the first energy indicator light to ignite according to the first energy indicator light ignition signal. If the first energy indicator light is on, the energy output of the first energy mode is normal and there is no fault in the energy output line of the first energy mode. If the first energy indicator light is off, there is a fault in the energy output line of the first energy mode. If the second energy indicator light is on, the energy output of the second energy mode is normal and there is no fault in the energy output line of the second energy mode. If the second energy indicator light is off, there is a fault in the energy output line of the second energy mode.

[0088] When the first energy indicator light is on, the ultrasonic scalpel performs ultrasonic ablation at the first energy level, indicating that the ultrasonic scalpel is not malfunctioning. When the first energy indicator light is on, the ultrasonic scalpel does not perform ultrasonic ablation, indicating that the ultrasonic scalpel is malfunctioning. When the second energy indicator light is on, the ultrasonic scalpel performs ultrasonic ablation at the second energy level, indicating that the ultrasonic scalpel is not malfunctioning. When the second energy indicator light is on, the ultrasonic scalpel does not perform ultrasonic ablation, indicating that the ultrasonic scalpel is malfunctioning.

[0089] In this embodiment of the invention, such a setting can intuitively display the real-time energy output status of the first energy mode and the second energy mode, and can quickly determine the fault node of the energy output line of the first energy mode or the second energy mode and the failure of the ultrasonic scalpel, thereby reducing the repair time of the ultrasonic scalpel and reducing the surgical risk for patients.

When the second trigger signal is input from the first trigger signal input terminal 29 or the second trigger signal input terminal 32, the protection circuit unit 51 controls the first output terminal 33 to connect with the third output terminal 35 or controls the second output terminal 34 to connect with the fourth output terminal 36 according to the second trigger signal.
