In response to the usage status signal, the main unit controls the light source corresponding to the instrument that outputs the usage status signal to switch between the first light-emitting mode and the second light-emitting mode to emit light.

[0025] The host responds to the switch signal output by the pre-operation pedal and controls the light source corresponding to the pre-operation pedal to emit light in the third light emission mode.

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0041] Electrosurgical instruments offer unique advantages over traditional surgical instruments and are widely used. There are many types of electrosurgical instruments, including energy devices such as high-frequency, ultrasonic, and microwave devices. In a single surgery, multiple electrosurgical instruments are often used in combination to achieve efficient and safe results.

[0042] During the use of electrosurgical instruments, these instruments are generally activated and controlled via foot pedals. To differentiate the activation and control of different functions, electrosurgical energy platforms often use a method of matching one function of each electrosurgical instrument with a foot switch. When switching electrosurgical instruments is required, for example, replacing a monopolar hook with a monopolar bending shear, the electrosurgical instrument needs to be changed manually, and the foot switch definition needs to be reset in the host interface to match the foot switch with the electrosurgical instrument. This process reduces efficiency and requires basic understanding and operating skills of the electrosurgical equipment.

[0043] To save time when changing electrosurgical instruments, multiple energy devices can be connected simultaneously in laparoscopic or multi-port robotic surgery. However, when changing electrosurgical instruments, it is still necessary to set the electrosurgical instruments and foot switches on the main unit.

[0044] To address this issue, a host device with multiple output interfaces was developed. This host device includes a display unit 216, and each output interface is connected to a foot switch, such as... Figure 1As shown, the monopolar output interface 1 corresponds to and matches the monopolar foot pedal interface 1, and the monopolar output interface 1 can be used to connect a monopolar instrument; the monopolar output interface 2 corresponds to and matches the monopolar foot pedal interface 2, and the monopolar output interface 2 can be used to connect another monopolar instrument; the bipolar output interface corresponds to and matches the bipolar foot pedal interface, and the bipolar output interface can be used to connect a bipolar instrument; the large vessel output interface corresponds to and matches the large vessel foot pedal interface, and the large vessel output interface can be used to connect a large vessel closure device; the ultrasonic scalpel output interface corresponds to and matches the ultrasonic scalpel foot pedal interface, and the ultrasonic scalpel output interface can be used to connect an ultrasonic scalpel. With the increase in the integrated functions of the electrosurgical energy platform, the number of foot switches required will continuously increase, leading to a larger equipment footprint, increased equipment procurement costs, and a higher failure rate. Furthermore, as the types of electrosurgical instruments connected to the foot switches increase, the number of corresponding foot switches will also increase accordingly. The interaction between these two types of foot switches can easily lead to confusion and the risk of incorrect energy excitation output. This application proposes an electrosurgical host system and an electrosurgical operating system that can reduce the risk of incorrect energy excitation output.

[0045] In one embodiment, such as Figure 2 As shown, an electrosurgical host system is provided, comprising:

[0046] The host 210 includes multiple interfaces 212 for connecting the instrument 230, and each interface 212 is equipped with a corresponding prompting module 214.

[0047] Multiple foot pedals 220; each foot pedal 220 includes at least one pedal 222, and each pedal 222 is connected to the host 210; each pedal 222 is used to output a switch signal; each pedal 222 is correspondingly provided with a sensing module 224, and each sensing module 224 is connected to the host 210; the sensing module 224 is used to detect whether there is an obstruction in the sensing area, and thus output a sensing signal.

[0048] When the device 230 is connected to the interface 212, the host 210 establishes a matching relationship between the device, the interface and the pedal; in response to the sensing signal, the host 210 determines the pre-operation pedal and controls the prompting module 214 of the interface corresponding to the pre-operation pedal to issue a prompt message in response to the sensing signal or switch signal of the pre-operation pedal.

[0049] Specifically, the main unit 210 can connect to multiple foot pedals 220, each foot pedal 220 having at least one pedal 222. Each pedal 222 is connected to the main unit 210. For example, the main unit 210 may include foot pedal interface 1 and foot pedal interface 2, each connecting to two foot pedals 220. Each foot pedal 220 may include two pedals 222. The main unit 210 may be provided with multiple interfaces 212 for connecting devices 230. Devices 230 can be connected to interfaces 212 of the main unit 210. When a device 230 is connected to an interface 212 of the main unit 210, the main unit 210 can establish a matching relationship between the connected device and the corresponding interface and pedal. The connected device 230 may include monopolar devices, bipolar devices, large vessel closure devices, and ultrasonic scalpels, etc. Taking the first interface of the host 210 connected to a monopolar device as an example, the host 210 can establish a matching relationship between the monopolar device, the monopolar interface, and the pedal. The monopolar interface connected to the monopolar device can be matched with the monopolar device. The host 210 can select an unassigned pedal with the corresponding function to control the monopolar device and match it with the monopolar device. For example, based on the function of the monopolar device, an unassigned electrocautery pedal or an unassigned electrocoagulation pedal can be matched to the monopolar device. By matching the device 230 with the pedal 222 one by one in the above manner, the number of foot pedals 220 can be reduced. After establishing the matching relationship between the device, interface, and pedal, a foot can be placed on pedal 222. The sensing module 224 of pedal 222 detects an obstruction within the corresponding sensing area and outputs a corresponding sensing signal to the host 210. Based on the received sensing signal, the host 210 determines that the pedal 222 with the obstruction within the sensing area is the pre-operation pedal and can control the prompting module 214 of the interface corresponding to the pre-operation pedal to issue a prompt message. If pedal 222 is pressed, pedal 222 can output a corresponding switch signal. For example, when pedal 222 is not pressed, pedal 222 can output a low-level switch signal, and when pedal 222 is pressed, pedal 222 can output a high-level switch signal. Based on the received switch signal, the host 210 can determine which pedal 222 has been pressed and control the prompting module 214 of the interface corresponding to the pressed pre-operation pedal to issue a corresponding prompt message. The prompt message issued by the prompting module 214 can include at least one of sound signals, light signals, electrical signals, mechanical signals, and text signals.

[0050] In some examples, the foot pedal 220 may include a single pedal 222 for switching the corresponding instrument 230 between working and stopped states. The foot pedal 220 may also include two pedals 222 for different functions, each matched with an instrument 230 for a different function, allowing for switching between working and stopped states. The interfaces 212 of the host 210 are reusable; each interface 212 can connect to the required instruments 230 according to the needs of the current surgery, without limiting the types of instruments that can be connected, thus enabling flexible configuration of the instruments 230. The sensing module 224 may be located on the surface or inside the pedal 222. The sensing module 224 can be sealed by injection molding to improve waterproof and dustproof capabilities. For example, the sensing module 224 may be a photoelectric sensing module, which can be encapsulated using a transparent or light-guiding plastic material. Figure 3As shown, the sensing module 224 may include a light source, such as an infrared transceiver diode, a photodiode, or a microwave transceiver antenna, a potentiometer, and a matching circuit. The potentiometer is used to adjust the detection distance to change the range of the sensing area. The sensing module 224 may include a VCC interface, a GND interface, and an OUT interface. The VCC interface is used to connect to the power supply, the GND interface is used to ground, and the OUT interface is used to connect to the main control circuit of the host 210. Correspondingly, the signal processing software for controlling the light source to emit light can be built into the control chip of the host 210. Taking an infrared transceiver diode (or phototransceiver diode) as an example, an infrared transceiver diode has strong adaptability to ambient light and can include at least one pair of infrared emitting diodes and infrared receiving diodes (or photoemitting diodes and photoreceiving diodes). The infrared emitting diode can emit infrared signals of a certain frequency (or the photoemitting diode emits photoelectric signals). When an obstacle, such as a foot, is encountered in the detection direction of the sensing module 224, the infrared signal (or photoelectric signal) is reflected back and received by the infrared receiving diode (or photoelectric receiving diode). After being processed by the matching circuit connected to the light source, the sensing signal (e.g., a low-level digital signal) can be output to the host 210 through the OUT interface. The sensing module 224 can include an indicator light, which can light up green to indicate that a sensing signal is output. The host 210 will control the prompt module 214 of the interface corresponding to the pedal where the sensing module is located to issue a prompt message based on the received sensing signal. The potentiometer can be adjusted by a knob to change the detection distance, which can be from 2cm to 50cm, to change the effective range of the sensing area. The VCC interface of the sensing module 224 can be connected to a power supply with a working voltage of 3.3V-5V. Infrared emitters and receivers (or photoelectric emitters and receivers) can be integrated. The emitted light of the required wavelength is modulated by a modulator and then emitted by the infrared emitter (or photoelectric emitter). The beam frequency of the emitted light and the emission power of the infrared emitter can be adjusted. At the same time, the potentiometer can change the range of the sensing area. When the operator's foot is outside the sensing area, the emitted light cannot be effectively reflected back to the infrared receiver (or photoelectric receiver). When the operator's foot is within the sensing area, the infrared receiver (or photoelectric receiver) can receive the reflected light corresponding to the emitted light and demodulate the reflected light to output a sensing signal to the host 210 for processing. The host 210 can determine the pre-operation pedal based on the sensing signal. The aforementioned sensing module 224 can effectively avoid interference from visible light.

[0051] In some examples, such as Figure 4As shown, the sensing module 224 may include a modulator and a current regulator. The current regulator can be connected to a VCC power supply and connected to the modulator to stabilize the modulator's output. The modulator can be connected to an infrared emitting diode (or photoelectric emitting diode) to drive the infrared emitting diode to emit corresponding light. When the infrared receiving diode detects reflected light, it will output a signal according to the intensity of the reflected light. The resistance and output voltage of the infrared receiving diode will change proportionally with the intensity of the received reflected light. Figure 5 As shown, the sensing module 224 may also include an amplifier, a rectifier and voltage regulator circuit, a demodulator, and a clock logic circuit. The amplifier can be connected to the infrared receiver (or photodetector), the demodulator, and the rectifier and voltage regulator circuit respectively. The clock logic circuit can be connected to the demodulator and the host 210 respectively. After the amplifier amplifies the output signal of the infrared receiver, it is transmitted to the host 210 through the demodulator and the clock logic circuit. The rectifier and voltage regulator circuit can be connected to the VCC power supply to rectify and regulate the amplifier and the demodulator. The host 210 can identify whether there is an obstruction in the sensing area of ​​the pedal 222 corresponding to the sensing module 224 according to the high and low level of the sensing signal, and then determine the pre-operation pedal before the pedal 222 is pressed. The host 210 can also connect to and control the corresponding display unit 216 to display the matching relationship between the device, the interface, and the pedal.

[0052] The electrosurgical host system of this application includes: a host, which includes multiple interfaces for connecting instruments, and each interface is provided with a corresponding prompting module; multiple foot pedals; each foot pedal includes at least one pedal, and each pedal is connected to the host; each pedal is used to output a switch signal; each pedal is provided with a corresponding sensing module, and each sensing module is connected to the host; the sensing module is used to detect whether there is an obstruction in the sensing area, thereby outputting a sensing signal; when an instrument is connected to an interface, the host establishes a matching relationship between the instrument, the interface, and the pedal, matching the instrument with the pedal one by one, which can reduce the number of foot pedals required, thereby reducing the equipment footprint of the electrosurgical host system; the host responds to the sensing signal to determine the pre-operation pedal, and responds to the sensing signal or switch signal of the pre-operation pedal to control the prompting module of the interface corresponding to the pre-operation pedal to issue a prompting message, and prompts the operator through the prompting message issued by the prompting module, so that the operator can know which pedal's sensing area is currently placed or which pedal is currently pressed without looking at the ground, and thus know whether the instrument held corresponds to the pedal being operated, reducing the risk of energy excitation output error and improving the efficiency of operation.

[0053] In one embodiment, foot pedal 220 includes an electro-cutting pedal and / or an electrocoagulation pedal;

[0054] When the host 210 detects that the interface 212 is connected to the device 230, if it determines that the function of the device 230 is electrocautery, it will match an unassigned electrocautery pedal with the device 230; if it determines that the function of the device 230 is electrocoagulation, it will match an unassigned electrocoagulation pedal with the device 230.

[0055] Specifically, foot pedal 220 may include at least one of an electric cutting pedal and an electrocoagulation pedal. For example... Figure 6 As shown, foot pedal 220 may include an electrocautery pedal and an electrocoagulation pedal, and device 230 may include a device 230 for performing electrocautery and a device 230 for performing electrocoagulation. If the host 210 detects that a device 230 for performing electrocautery is connected to interface 212, it can match one of the unassigned pedals 222 with the device 230; if the host 210 detects that a device 230 for performing electrocoagulation is connected to interface 212, it can match one of the unassigned pedals 222 with the device 230.

[0056] In one embodiment, such as Figure 2 As shown, the prompt module 214 includes a light source, wherein at least one light source is provided at each interface 212;

[0057] The host 210 is connected to each light source. In response to the sensing signal, the host 210 controls the light source at the interface corresponding to the pedal 222 that outputs the sensing signal to switch between the first light-emitting mode and the second light-emitting mode to emit light.

[0058] The host 210 responds to the switch signal output by the pre-operation pedal and controls the light source at the interface corresponding to the pre-operation pedal to emit light in the third light-emitting mode.

[0059] Specifically, light sources can be installed at each interface 212. After the instrument 230 is connected to the interface 212, if no operation is performed on the pedal 222 corresponding to the instrument 230, the host 210 can control the light source at the interface corresponding to the pedal 222 to be in the first light-emitting mode. This indicates that no operation has been performed on the pedal 222, and the pedal 222 corresponding to the light source at that interface 212 is in an operable state. If the host 210 determines, based on the received sensing signal, that a pedal 222 with an obstruction in the sensing area is a pre-operation pedal, the host 210 can control the light source at the interface corresponding to the pedal 222 to be in the first light-emitting mode. The light source at the interface is in the second light-emitting mode, indicating that the pedal 222 corresponding to the interface 212 where the light source is located is a pre-operation pedal. The operator can determine whether the currently held instrument 230 corresponds to the pre-operation pedal based on the second light-emitting mode of the light source, prompting the operator to move their foot to the sensing area of ​​the pedal 222 before pressing down on the instrument 230, reducing the risk of incorrect energy excitation output. Furthermore, when the operator moves their foot out of the sensing area of ​​the pedal 222, the light source at the interface corresponding to the pedal 222 can switch back to the first light-emitting mode. When the pre-operation pedal is pressed down, the pre-operation pedal can output a corresponding switch signal. The host 210 can determine whether the pre-operation pedal has been pressed based on the received switch signal. The host 210 can also control the light source at the interface corresponding to the pressed pre-operation pedal to be in the third light-emitting mode based on the switch signal, indicating that the pre-operation pedal corresponding to the interface 212 where the light source is located has been pressed down. The operator can know based on the third light-emitting mode that energy excitation is being performed on the instrument 230 corresponding to the pedal 222, reducing the risk of misoperation and improving operational safety.

[0060] In some examples, the first, second, and third emission modes can be distinguished by changing the emission color, flicker frequency, and brightness of the light source. In the first emission mode, the light source can emit gray light; in the second emission mode, the light source can emit yellow light; and in the third emission mode, the light source can emit red light.

[0061] In one embodiment, the host 210 further includes a display unit 216 for displaying the matching relationship and / or warning information between the device, the interface and the pedal.

[0062] Specifically, the host 210 may include a display unit 216, which can display the matching relationship and / or warning information between the instrument, the interface, and the pedal. For example, when the host 210 establishes a matching relationship between the instrument 230, the monopolar interface, and the pedal, the host 210 can control the display unit 216 to display the established matching relationship between the instrument 230, the monopolar interface, and the pedal, so as to prompt the operator to operate the instrument 230 and the pedal 222 corresponding to the instrument 230. When the host 210 determines that the pre-operated pedal and the pedal 222 that has been stepped on are inconsistent, the host 210 can control the display unit 216 to display warning information, so as to prompt the operator that there is a possibility of misoperation of the pedal 222 that has been stepped on.

[0063] In some examples, when the host 210 has multiple energy excitation functions, such as monopolar, bipolar, large blood vessel, and ultrasonic scalpel energy excitation functions, the corresponding instruments 230 can be connected to the interface 212 of the host 210 one by one according to the needs of the surgery. The host 210 can assign available foot pedals 220 to the instruments 230 and the connected interfaces 212, ensuring that all instruments 230 required for the surgery have corresponding foot pedals 222 to match. During use, there is no need to change the instruments 230 or re-set the instruments 230 and foot pedals 222. The corresponding foot pedals 222 can be directly operated to enable the host 210 to excite the corresponding instruments 230. Before and during the excitation process, the display unit 216 can display the matching relationship between the instruments, interfaces, and foot pedals to avoid misoperation and improve the safety of equipment use. Figure 7As shown, the main unit 210 may include two monopolar interfaces, one bipolar interface, and one large vessel interface; both the first and second foot pedals may include an electrocautery pedal and an electrocoagulation pedal. When the main unit 210 is connected to a monopolar hook via the corresponding interface 212, the main unit 210 can match the electrocautery pedal of the first foot pedal with the monopolar hook; when the main unit 210 is connected to a monopolar curved scissor via the corresponding interface 212, the main unit 210 can match the electrocoagulation pedal of the first foot pedal with the monopolar curved scissor; when the main unit 210 is connected to a bipolar electrocoagulation forceps via the corresponding interface 212, the main unit 210 can match the electrocautery pedal of the second foot pedal with the bipolar electrocoagulation forceps; when the main unit 210 is connected to a large vessel closure device via the corresponding interface 212, the main unit 210 can match the electrocoagulation pedal of the second foot pedal with the large vessel closure device. After the above-mentioned devices 230 and pedals 222 are matched one by one, the main unit 210 can control the energy excitation of each device 230 based on the operation of each pedal 222 through the built-in control program. Taking the first foot pedal's electrocautery pedal as an example, when the operator's foot is placed within the sensing area of ​​the electrocautery pedal, the sensing module 224 of the electrocautery pedal can detect an obstruction within the sensing area. Based on the matching relationship between the first foot pedal's electrocautery pedal and the monopolar hook, the host 210 can predict that the operator will perform a monopolar hook activation operation. At this time, the host 210 can control the light source at the interface corresponding to the monopolar hook to illuminate, or control the light source set on the monopolar hook to illuminate. The display unit 216 can display "Currently performing electrocautery operation, using foot pedal 1 for electrocautery activation, instrument 230 connection and activation normal." The display unit 216 may include a display screen connected to the host 210 and related circuitry. Figure 8 As shown, when the operator's foot is placed in the sensing area of ​​the electric cutting pedal, if the host 210 cannot control the light source at the interface corresponding to the single-pole electric hook to illuminate, the display unit 216 can display "Current triggering failure, please check if the adapter and foot pedal connection is abnormal".

[0064] In some examples, the number of interfaces 212 can be 4, 5, or 6; the number of foot pedals 220 can be 2 or 3; the interface 212 can include at least one of a monopolar interface, a bipolar interface, a large blood vessel closure interface, and an ultrasonic scalpel interface, or it can be a multiplexed interface for instruments 230 with different functions.

[0065] In one embodiment, such as Figure 2 As shown, an electrosurgical system is provided, comprising:

[0066] The host 210 includes multiple interfaces 212, and each interface 212 is equipped with a corresponding prompt module 214;

[0067] Multiple instruments 230 are connected to one interface 212. Each instrument 230 is equipped with an instrument sensor, and each instrument sensor is connected to the host 210. The instrument sensor is used to output a usage status signal in response to the use of the instrument 230.

[0068] Multiple foot pedals 220; each foot pedal 220 includes at least one pedal 222, and each pedal 222 is connected to the host 210; each pedal 222 is used to output a switch signal; each pedal 222 is correspondingly provided with a sensing module 224, and each sensing module 224 is connected to the host 210; the sensing module 224 is used to detect whether there is an obstruction in the sensing area, and thus output a sensing signal.

[0069] When the device 230 is connected to the interface 212, the host 210 establishes a matching relationship between the device, the interface, and the pedal; the host 210 determines the pre-operation pedal in response to the sensing signal; and determines the pre-operation device in response to the usage status signal; the host 210 controls the prompting module 214 of the interface corresponding to the pre-operation pedal to issue a first prompt message in response to the sensing signal or switch signal of the pre-operation pedal, and controls the prompting module 214 of the interface corresponding to the pre-operation device to issue a second prompt message in response to the usage status signal of the pre-operation device.

[0070] Specifically, compared to the main electrosurgical system, the electrosurgical system includes multiple instruments 230, which may include monopolar instruments, bipolar instruments, large vessel closure devices, and ultrasonic scalpels. The monopolar and bipolar instruments can be connected to the main unit 210 via interface 212. When the main unit 210 outputs excitation energy to the instruments 230, the energy is conducted to the active electrode, which generates a corresponding temperature on the tissue, achieving the desired effect (e.g., coagulation or cutting). Afterward, the current returns through a loop formed by the grounding electrode or the bipolar instrument. The large vessel closure device provides vascular closure when it is excited by energy from the main unit 210. The ultrasonic scalpel can be connected to the main unit 210 via interface 212. When the main unit 210 outputs excitation energy to the ultrasonic scalpel, the high-frequency vibration generated by the ultrasonic scalpel tip generates heat energy upon contact with the tissue, thereby achieving functions such as coagulation or cutting. Each instrument 230 is equipped with an instrument sensor. The instrument sensor outputs a usage status signal to the host 210 in response to the use of the instrument 230. The host 210 can then determine the instrument to be operated based on the usage status signal. For example, the instrument sensor may include a gravity sensor, an acceleration sensor, and a pressure sensor. When the operator picks up or holds the instrument 230, the instrument sensor outputs a corresponding usage status signal to the host 210. The host 210 then determines the instrument 230 for which the operator will perform the relevant operation and designates it as the pre-operation instrument. The host 210 can control the prompting module 214 of the corresponding interface of the pre-operation instrument to issue a second prompt message in response to the usage status signal of the pre-operation instrument. This message indicates to the operator which interface 212 the pre-operation instrument is connected to and that the interface 212 of the pre-operation instrument and the host 210 are in a valid electrical connection state. As described in the embodiment of the electrosurgical host system, after establishing the matching relationship between the instrument, interface, and pedal, a foot can be placed on pedal 222. The sensing module 224 of pedal 222 detects an obstruction within the corresponding sensing area and outputs a corresponding sensing signal to the host 210. Based on the received sensing signal, the host 210 determines that the pedal 222 with the obstruction within the sensing area is the pre-operation pedal and can control the prompting module 214 of the interface corresponding to the pre-operation pedal to issue a first prompt message. If pedal 222 is pressed, pedal 222 can output a corresponding switch signal. For example, when pedal 222 is not pressed, pedal 222 can output a low-level switch signal, and when pedal 222 is pressed, pedal 222 can output a high-level switch signal. Based on the received switch signal, the host 210 can determine which pedal 222 has been pressed and can control the prompting module 214 of the interface corresponding to the pressed pre-operation pedal to issue a corresponding first prompt message. The host 210 can also compare whether the pedal corresponding to the pre-operation instrument is consistent with the pressed pedal and issue a corresponding prompt message.The first and second prompt messages may include at least one of the following: sound signals, light signals, electrical signals, mechanical signals, and text signals.

[0071] The electrosurgical system of this application includes: a main unit, which includes multiple interfaces, each interface being equipped with a corresponding prompting module; multiple instruments, each connected to one interface, each instrument being equipped with an instrument sensor, and each instrument sensor being connected to the main unit, the instrument sensor being used to output a usage status signal in response to the use of the instrument; multiple foot pedals, each foot pedal including at least one pedal, each pedal being connected to the main unit; each pedal being used to output a switch signal; each pedal being equipped with a corresponding sensing module, each sensing module being connected to the main unit; the sensing module being used to detect whether there is an obstruction in the sensing area, thereby outputting a sensing signal; when an instrument is connected to an interface, the main unit establishes a matching relationship between the instrument, the interface, and the pedals, matching the instrument and the pedal one by one, which can reduce the number of foot pedals required, thereby reducing the equipment footprint of the electrosurgical main unit system; the main unit responds... Based on the sensing signal, the pre-operation pedal is determined; in response to the usage status signal, the pre-operation device is determined; the main unit, in response to the sensing signal or switch signal of the pre-operation pedal, controls the prompt module of the interface corresponding to the pre-operation pedal to issue a first prompt message, so that the operator can know which pedal's sensing area is currently placed or which pedal is currently pressed without looking at the ground. In response to the usage status signal of the pre-operation device, the main unit controls the prompt module of the interface corresponding to the pre-operation device to issue a second prompt message, so that the main unit can automatically identify whether the current pre-operation pedal and the pre-operation device correspond. This allows the main unit to provide the operator with more prompt information, and even the main unit can make more safety settings based on the prompt information, reducing the risk of energy excitation output errors, improving operational efficiency, and enhancing the system's intelligence.

[0072] In one embodiment, the system also includes an alarm module connected to the host 210;

[0073] The host 210 determines the target operating pedal corresponding to the pre-operation device based on the matching relationship through the pre-operation device;

[0074] If the pre-operation pedal is different from the target operation pedal, the host 210 controls the alarm module to issue an alarm signal.

[0075] Specifically, upon detecting that the device 230 is connected to the interface 212 of the host 210, the host 210 can establish a matching relationship between the device, the interface, and the pedal. Based on this matching relationship, the host 210, upon identifying the device to be operated, determines the target operating pedal corresponding to it. The target operating pedal is the pedal 222 that the operator needs to press, while the pre-operation pedal is the pedal 222 that the operator will actually press. Furthermore, if the host 210 determines that the pre-operation pedal and the target operating pedal are different, it indicates that the pedal 222 that the operator is actually about to press cannot generate energy for the device to be operated. In this case, the host 210 controls the alarm module to issue an alarm signal to indicate that the operator's foot is on the pedal 222 that does not correspond to the device to be operated, thus preventing the operator from pressing the pre-operation pedal.

[0076] In one embodiment, the prompting module 214 includes a light source, wherein two light sources are provided at each interface 212, one of which is matched with the pedal 222 corresponding to the interface 212, and the other light source is matched with the instrument 230 corresponding to the interface 212.

[0077] The main unit 210 is connected to each light source. In response to the sensing signal, the main unit 210 controls the light source corresponding to the pedal 222 that outputs the sensing signal to switch between the first light-emitting mode and the second light-emitting mode to emit light. In response to the usage status signal, the main unit 210 controls the light source corresponding to the device 230 that outputs the usage status signal to switch between the first light-emitting mode and the second light-emitting mode to emit light.

[0078] The host 210 responds to the switch signal output by the pre-operation pedal and controls the light source corresponding to the pre-operation pedal to emit light in the third light emission mode.

[0079] Specifically, at least two light sources can be provided at each interface 212. For the light source matched with the pedal 222 corresponding to the interface 212, after the instrument 230 is connected to the interface 212, if no operation is performed on the pedal 222 corresponding to the instrument 230, the host 210 can control the light source matched with the pedal 222 corresponding to the interface 212 to be in the first light-emitting mode, which indicates that no operation has been performed on the pedal 222 and the pedal 222 matched with the light source is in an operable state; if the host 210 determines, based on the received sensing signal, that the pedal 222 with an obstruction in the sensing area is a pre-operation pedal, the host 210 can control the light source matched with the pedal 222 corresponding to the interface 212 to be in the second light-emitting mode, which indicates that the pedal 222 matched with the light source is a pre-operation pedal; when the operator moves his foot out of the sensing area of ​​the pedal 222, the light source matched with the pedal 222 can switch back to the first light-emitting mode. When the pre-operation pedal is pressed, the pre-operation pedal can output a corresponding switch signal. The host 210 can determine whether the pre-operation pedal has been pressed based on the received switch signal. The host 210 can also control the light source at the interface corresponding to the pressed pre-operation pedal to be in the third light emission mode based on the switch signal, so as to indicate that the pre-operation pedal corresponding to the interface 212 where the light source is located has been pressed. The operator can know that the device 230 corresponding to the pedal 222 is being excited based on the third light emission mode, which can reduce the risk of misoperation and improve the safety of operation.

[0080] For the light source that matches the device 230 corresponding to interface 212, the device sensor set on the device 230 responds to the use of the device 230 and outputs a usage status signal to the host 210. Then, the host 210 can determine the device 230 picked up or held by the operator as the pre-operation device based on the received usage status signal, and determine the current usage status of the pre-operation device based on the received usage status signal. For example, if the current usage status of the pre-operation device is that the operator is holding the pre-operation device, the light source corresponding to the pre-operation device can be controlled to emit light in the second light emission mode. If the current usage status of the pre-operation device is that the operator is not holding the pre-operation device, the light source corresponding to the pre-operation device can be controlled to emit light in the first light emission mode. The light source corresponding to the operating device 230 can switch between the first light emission mode and the second light emission mode to emit light as the current usage status of the pre-operation device changes. It should be noted that the first light emission mode of the light source corresponding to pedal 222 can be the same as the first light emission mode of the light source corresponding to instrument 230, and the second light emission mode of the light source corresponding to pedal 222 can be the same as the second light emission mode of the light source corresponding to instrument 230. When the operator holds the instrument 230 to be operated and their foot is within the sensing area of ​​pedal 222, if both the light source corresponding to pedal 222 and the light source corresponding to instrument 230 of the same interface emit light in the second light emission mode, it indicates that the pedal 222 and instrument 230 are connected normally. In some examples, the first light emission mode can be yellow light, the second light emission mode can be green light, and the third light emission mode can be red light.

[0081] Furthermore, for the same interface 212, the operator can determine whether the pedal 222 and the instrument 230 correspond to each other, and whether the pre-operation instrument and the pre-operation pedal correspond, based on the light emission mode of the light source matched with the pedal 222 corresponding to the interface 212 and the light emission mode of the light source matched with the instrument 230 corresponding to the interface 212. For example, if the light source matched with the pedal 222 corresponding to the same interface 212 is in the first light emission mode and the light source matched with the instrument 230 is in the first light emission mode, it indicates that the pedal 222 and the instrument 230 corresponding to the interface 212 are not connected. If the light source matched with the pedal 222 corresponding to the interface 212 is in the second light emission mode and the light source matched with the instrument 230 corresponding to the interface 212 is in the second light emission mode, it indicates that the pedal 222 and the instrument 230 corresponding to the interface 212 are connected, the pre-operation instrument and the pre-operation pedal correspond, and the operator can perform the next operation on the pre-operation instrument and the pre-operation pedal. When the operator holds the instrument 230 to be operated and their foot is within the sensing area of ​​the pedal 222, if the light emission mode of the light source matched by the pedal 222 corresponding to the interface 212 is inconsistent with the light emission mode of the light source matched by the instrument 230 corresponding to the interface 212, for example, if the light emission mode of the light source matched by the pedal 222 corresponding to the same interface 212 is the first light emission mode and the light emission mode of the light source matched by the instrument 230 is the second light emission mode, or if the light emission mode of the light source matched by the pedal 222 corresponding to the same interface 212 is the second light emission mode and the light emission mode of the light source matched by the light source matched by the instrument 230 is the first light emission mode, it can indicate that the pedal 222 and the instrument 230 corresponding to the same interface are not connected accordingly. For example, the instrument 230 held by the operator does not correspond to the pedal 222 where the foot is located. The two light sources at the same interface 212 can prompt the operator to move their foot to another pedal 222 in time before pressing the pedal 222, so that the instrument 230 held corresponds to the pedal 222 where the foot is located, thereby reducing the risk of energy excitation output error.

[0082] In one embodiment, the host 210 further includes a host display unit; the host display unit is used to display warning information when the pre-operated pedal is different from the target operating pedal.

[0083] Specifically, the host 210 can determine the target operating pedal corresponding to the pre-operated device based on the matching relationship between the device, interface, and pedal. The target operating pedal corresponding to the pre-operated device is the pedal 222 that the operator needs to press, while the pre-operated pedal is the pedal 222 that the operator will actually press. Furthermore, if the host 210 determines that the pre-operated pedal and the target operating pedal are different, it indicates that the pedal 222 that the operator is about to press cannot achieve energy activation of the pre-operated device. In this case, the host display unit displays a warning message to indicate that the operator's foot is placed on the pedal 222 that does not correspond to the pre-operated device, thus reminding the operator that pressing the pre-operated pedal will cause the pre-operated device to fail to be activated or may lead to other misoperations.

[0084] In some examples, the host display unit may include a display screen and related circuitry connected to the host 210. When the pre-operation pedal differs from the target operation pedal, the host display unit can show the connection relationship between the pre-operation pedal and the corresponding device 230, as well as the connection relationship between the target operation pedal and the pre-operation device, and provide a prompt indicating that the pre-operation pedal and the pre-operation device cannot be connected. The operator can then adjust the pedal 222 under their foot according to this prompt until the pre-operation pedal matches the target operation pedal. When the pre-operation pedal matches the target operation pedal, the operator can correctly activate the pre-operation device by pressing the pre-operation pedal. When the pre-operation pedal differs from the target operation pedal, the host 210 can perform a safety lock operation on the pre-operation pedal; for example, even if the pre-operation pedal is pressed, power cannot be supplied, and the output power of the interface corresponding to the pre-operation pedal cannot be controlled.

[0085] In one embodiment, the surgical system further includes an operation guidance unit. If the pre-operation pedal and the target operation pedal are not the same, the host 210 outputs operation guidance information based on the relative position between the pre-operation pedal and the target operation pedal, and presents it through the operation guidance unit.

[0086] Specifically, the operation guidance unit may include a host display unit or a display device connected to the host 210 (e.g., a head-mounted display or a screen), and the operation guidance unit may also provide voice prompts. If the pre-operation pedal and the target operation pedal are different, the host 210 can obtain the relative position between the pre-operation pedal and the target operation pedal, and output operation guidance information based on the relative position between the pre-operation pedal and the target operation pedal. The operation guidance unit may display or provide voice prompts for the operation guidance information.

[0087] In some examples, the relative position between the pre-operation pedal and the target operation pedal can be determined based on the preset relative position between each pedal 222, or by setting a corresponding position sensor on each pedal 222 to determine the relative position between each pedal 222, and further obtaining the relative position between the pre-operation pedal and the target operation pedal based on the determined pre-operation pedal and target operation pedal.

[0088] In one embodiment, each pedal 222 is provided with a position sensor; the host 210 is connected to each position sensor respectively, and the host 210 determines the relative position between the pre-operation pedal and the target operation pedal based on the output signal of each position sensor.

[0089] Specifically, position sensors can be installed on each pedal 222, and the host 210 can connect to each position sensor. Based on the output signals received from each position sensor, the relative position between each pedal 222 can be determined, and then the relative position between the pre-operation pedal and the target operation pedal can be obtained according to the determined pre-operation pedal and target operation pedal.

[0090] In some examples, the host 210 can output operation guidance information based on the relative position between the pre-operation pedal and the target operation pedal. The operation guidance unit can output voice prompts based on the operation guidance information to guide the operator on how to move their feet to efficiently find the position of the target operation pedal. Alternatively, the host display unit or a display device connected to the host 210 can display a positional relationship image between the pre-operation pedal and the target operation pedal to guide the operator on how to quickly move their feet based on the positional relationship image.

[0091] In one embodiment, a host 210 is provided, the internal structure of which can be shown in the following diagram. Figure 9As shown, the host 210 includes a processor, memory, input / output interface, communication interface, display unit, and input device.
