[0060] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0061] It should be noted that among surgical instruments, some surgical equipment are equipped with foot pedals, main units and handles. Doctors can output different control signals to the main unit through the foot pedal. After receiving the control signal, the main unit can control the handle to perform different actions according to different control signals, thereby driving the tool to complete the operation.

[0062] The existing foot pedal and the host can support wired and wireless connections to transmit control signals, but when the user switches from wired to wireless, if the foot pedal has not been wirelessly connected to the host before, when making a wireless connection, the foot pedal needs to know the host address of the host before it can send a connection request to the host for wireless connection, which requires the user to manually pair the foot pedal with the host so that the foot pedal can obtain the host address of the host before a wireless connection can be made, resulting in cumbersome operation and poor user experience.

[0063] In order to solve the above-mentioned defects, the present embodiment provides a wireless connection method, which is applied to the foot pedal in the surgical device on the one hand, and to the host of the surgical device on the other hand. Since the host address stored in the foot pedal in the present embodiment can be the address sent by the host when the foot pedal is connected to the host by wire, after the foot pedal enters the wireless connection mode, the stored host address can be obtained, and the generated connection request can be sent to the host based on the host address. After receiving the connection request, the host can establish a wireless connection with the foot pedal. Compared with the existing method that requires the user to manually pair the foot pedal with the host so that the foot pedal obtains the host address of the host, the present embodiment can enable the host to send the address to the foot pedal for storage when the foot pedal is connected to the host by wire, thereby eliminating the need for user operation, simplifying the operation process, and improving the user experience.

[0064] For ease of understanding, the following combination Figures 1 to 7 The wireless connection method provided in the embodiment of the present application and the surgical equipment provided in the following embodiment are introduced in detail.

[0065] The present application embodiment provides a wireless connection method, referring to Figure 1 as well as Figure 2 , Figure 1 This is a schematic diagram of the structure of the surgical device in the first embodiment of the wireless connection method of this application. Figure 2 This is a flow chart of the first embodiment of the wireless connection method of the present application.

[0066] like Figure 1 As shown, the surgical device in this embodiment may include: a foot pedal and a host, wherein the number of the host can be one, the number of the foot pedal can be one or more, and this embodiment uses two foot pedals for illustration (i.e. Figure 1 The above surgical equipment may also include a handle, wherein the handle may be a component used by the user to perform surgical operations, including but not limited to a drill handle, a milling handpiece, a grinding handpiece or a planing handpiece, etc., and this embodiment does not limit this. At the same time, the number of the above handles may be one or more. This embodiment uses two handles for illustration (i.e. Figure 1 In the embodiment, one foot pedal controls one handle.

[0067] Specifically, a main control board and several handle driving boards may be provided in the host in this embodiment. The number of handle driving boards may determine how many handles the host can support for operation at the same time, and the specific number is not limited in this embodiment; wherein each foot pedal may be connected to the main control board, and the main control board is then connected to the corresponding handle through each handle driving board.

[0068] The pedal may be provided with a pedal driver, the main control board may be provided with a main program, and the handle driver may be provided with a handle driver. In this embodiment, the pedal 1 corresponds to the control handle 1, and the pedal 2 corresponds to the control handle 2. In actual use, when the user steps on the pedal, the pedal may generate a control signal through the pedal driver and transmit it to the main control board. The main control board then analyzes the control signal and transmits the analysis result to the corresponding handle driver board. The handle driver in the handle driver board generates a corresponding operation signal according to the analysis result and transmits it to the corresponding handle. After receiving the operation signal, the handle may perform a corresponding operation, such as starting work, stopping work, or the corresponding function of the handle.

[0069] like Figure 2 As shown, in this embodiment, the above method can be applied to a foot pedal of a surgical device, and the surgical device can also include a host, and the method includes:

[0070] Step S10: when the host is connected to the host by wire, obtaining and storing the host address sent by the host;

[0071] Step S20: when entering the wireless connection mode is detected, obtaining the stored host address.

[0072] It can be understood that since the host and the pedal in this embodiment can support wired connection and wireless connection, the wired connection can be connected through the Recommended Standard 485 (RS485), and the wireless connection can be connected through Bluetooth connection. Therefore, the host and the pedal in this embodiment have two modes, one wired connection mode and one wireless connection mode.

[0073] In this embodiment, a switch can be set on the foot pedal, and the user can control the foot pedal to enter the wired connection mode or the wireless connection mode through the switch. Of course, as another implementation method, the foot pedal can detect whether there is a cable connected to the host in the wired connection interface after power-on. If there is, it is in the wired connection mode, and if not, it enters the wireless connection mode. The specific switching method can be set according to the actual situation, and this embodiment does not limit this. At the same time, the host can be equipped with a display screen, and the user can set the host to enter the wireless connection mode through the display screen.

[0074] It should be understood that the host address may be the corresponding host address stored in the host when the pedal is previously connected to the host by wire. In this embodiment, when the host and the pedal are connected by wire, the host may send the host address stored in itself to the pedal, and the pedal may store the host address in its own storage space for preservation.

[0075] Step S30: Generate a connection request based on the host address and send it to the host, so that the host establishes a wireless connection with the pedal according to the connection request.

[0076] It should be noted that when the host disconnects the wired connection with the pedal and enters the wireless connection mode, it can continuously monitor whether a connection request sent by the pedal is received. The above connection request can be a request for the pedal to establish a wireless connection with the host. After obtaining the stored host address, the pedal can generate a connection request and send the connection request to the corresponding host based on the host address. When the host detects that the connection request has been received, it can establish a wireless connection with the pedal based on the connection request. Since the host address stored in the pedal in this embodiment is the host address sent by the host when the pedal is connected to the host by wire, there is no need for the user to manually pair the pedal with the host so that the pedal obtains the host address of the host, thereby simplifying the operation process and improving the user experience.

[0077] Furthermore, in order to enable the pedal to receive the host address of the host when connected to the host by wire, in this embodiment, the above step S10 includes:

[0078] Step S11: when it is detected that the current power supply mode is cable power supply, it is determined that there is a wired connection with the host, and a downlink instruction sent by the host is received.

[0079] It is understandable that the above downlink instruction can be an instruction for the host to query the pedal. In this embodiment, when the host is powered on, the downlink instruction can be generated and sent according to a certain preset time interval (such as 5 minutes, etc.);

[0080] In this embodiment, the cable used to connect the pedal and the host can not only realize the command transmission between the pedal and the host, but also power the pedal through the power supply of the host; at the same time, there is also a battery inside the pedal. When the pedal is not plugged into the connecting cable, the battery is in a working state, and when the pedal is plugged into the connecting cable, the battery is in a non-working state or in a charging state. Therefore, after the pedal is powered on, the current power supply mode can be detected. For ease of understanding, refer to Figure 3 , Figure 3 This is a schematic diagram of the foot pedal workflow in the first embodiment of the wireless connection method of this application; Figure 3 As shown, after the foot is powered on (i.e. Figure 3 The current power supply mode (i.e. Figure 3 When the power provided by the cable is detected, it is determined to be cable-powered; when the power provided by the pedal's own battery is detected, it is determined to be battery-powered; at the same time, when it is powered by the cable, it can be determined to be a wired connection, and when it is powered by the battery, it can be determined to be a wireless connection.

[0081] After confirming that the cable is powered, the pedal can communicate with the host (i.e. Figure 3 The foot pedal then continuously detects whether a downlink command is received (i.e. Figure 3 Since the host and the pedal are connected by wire, the host can transmit the downlink command to the pedal.

[0082] Step S12: upon receiving the downlink instruction, query whether a host address has been stored;

[0083] Step S13: when the host address is not stored, obtaining the host address carried in the downlink instruction, and storing the host address.

[0084] It should be noted that in this embodiment, the downlink instruction may carry the host address corresponding to the host. In actual use, the host may generate a downlink instruction with its own host address and send it to the pedal. When the pedal receives the downlink instruction, it may determine whether it has stored the host address. If the host address is not stored, it may be indicated that the pedal is a "new pedal" at this time, and then the pedal may store the host address carried in the downlink instruction.

[0085] Furthermore, considering that when a host address is stored in the pedal, it can be said that the pedal has been bound to the host corresponding to the stored host address, and when a new host is connected to the pedal by wire, in order to prevent the binding from being directly updated, in this embodiment, after the above step of determining whether the host address is stored, the following is further included:

[0086] When the host address has been stored, the stored host address is obtained, and the host address is fed back to the host through an uplink instruction, so that when the host determines that the actual host address does not match the fed-back host address and receives an update binding operation input by the user, the actual host address is sent;

[0087] The actual host address is obtained and stored.

[0088] It should be noted that the actual host address may be a host address stored by the host itself, the fed-back host address may be a host address stored by the pedal itself, and the uplink instruction may be an instruction carrying the host address stored by the pedal. When the pedal currently has a host address stored, the stored host address may be obtained and fed back to the host through the uplink instruction. When the host receives the uplink instruction, it may obtain the host address stored by the pedal, and then determine whether it matches its actual host address.

[0089] When the host detects a match, it means that the binding relationship has not changed, and there is no need to send the actual host address to the pedal for storage again. The pedal can communicate with the host normally and transmit the control signal generated by the pedal to the host through the cable for related control operations (i.e. Figure 3 RS485 returns device status data);

[0090] When the host detects a mismatch, it may indicate that the host address previously stored in the pedal is not the host address of the host, or that the pedal was not wirelessly connected to the host before. The pedal is a "new pedal" for the host, and the binding relationship may need to be updated. In order to determine whether an update is needed, the host may display an inquiry window on the display screen, specifically asking the user whether to update. The user may click on the screen as needed. When the result clicked by the user is "do not update", it may indicate that the user hopes that the pedal may be temporarily used for the host at this time, and only needs to maintain the current wired connection communication. Then, the host may receive the user's input of the non-update binding operation, and the pedal does not adjust the stored host address.

[0091] When the result clicked by the user is "update", it means that the user hopes that the pedal may be used for a long time for the host, and then the host can generate a reset instruction according to the update binding operation input by the user (i.e. Figure 3 command: 91H) to the pedal, the host address can be set in the reset command; when the pedal receives the reset command, it can feedback its own pedal address to the host (i.e. Figure 3 RS485 returns the local Bluetooth address) so that the host can save the pedal address for subsequent wireless connection through the host; at the same time, the pedal can obtain the actual host address of the host carried in the reset instruction (i.e. Figure 3 Get the Bluetooth remote address) and clear the previously stored host address (i.e. Figure 3 Clear the remote address in the remote address), save the actual host address of the host as the new host address to complete the reset, so as to obtain and store the actual host address (ie Figure 3 The remote address is reset in the remote address field to complete the update of the binding relationship. Then, when the pedal enters the wireless connection mode, it can directly connect to the host wirelessly according to the actual host address stored, without manual operation by the user.

[0092] Furthermore, considering that conventional foot pedals are generally provided with only one pedal, and the pedal can only be used to control the opening and closing of the handle, resulting in a relatively single function, in order to solve the above defects, the present embodiment can set the foot pedal to be steplessly continuously adjusted, which can be achieved by setting a sensor (such as a pressure sensor) or a Hall element in the foot pedal, etc., and the present embodiment does not limit this. Then, when the user steps on the pedal, as the pedal is stepped on more deeply, the control signal that can be output is enhanced, and the host can control the operation of the handle to be stronger and stronger (for example, the handle speed is getting faster and faster, or the output power is getting higher and higher, etc.), and when the pedal reaches the limit, the host can control the operation of the handle to reach the limit value (for example, the speed reaches the preset speed upper limit value).

[0093] In order to further increase the functional diversity, in this embodiment, several buttons can be set on the pedal. The specific button positions can be set according to actual conditions. In this embodiment, three buttons can be set on the pedal at the front end of the pedal, which are respectively recorded as the left button, the middle button and the right button; and different functions are set for different buttons. For example, the user steps on the left button to turn on / off the pedal; the user steps on the middle button to switch the function of the handle controlled by the pedal (that is, when the host is connected to a pedal and two handles, the two handles can be controlled by one pedal respectively); the user steps on the right button, which may include two situations, short press and long press. When the connected handle is a planing handle, long pressing the right button of the pedal can make the host enter the state of adjusting the planing handle window, that is, the state of controlling the rotation angle window of the planing handle. Short pressing the right button again can adjust the direction of the window, such as rotating by a certain number of degrees, etc. Then stepping on the right button again can exit the state of adjusting the planing handle window.

[0094] It should be emphasized that the specific functions of the above-mentioned different buttons can be set according to actual conditions. This embodiment is only used for illustration but not for limitation.

[0095] Furthermore, in order to facilitate the display of the status, the present embodiment can set indicator lights on both the handle and the pedal, and display the status together with the display screen of the host. And because the host in the present embodiment can be connected to two handles and two pedals, the indicator lights and the display screen of the host in the present embodiment can display the following content:

[0096] Scenario 1: When only one pedal is connected and it is channel 1 of the main unit, the work interface of pedal channel 1 on the display screen can display the type of the connected handle, and the icon of the work interface can be displayed in blue; the indicator light on the handle can be displayed in blue, and the indicator light on the pedal can be displayed in blue;

[0097] Scenario 2: When only one pedal is connected and it is channel 2 of the main unit, the work interface of pedal channel 2 on the display screen can show the type of the connected handle, and the icon of the work interface can be displayed in orange; the indicator light on the handle can be displayed in orange, and the indicator light on the pedal can be displayed in orange;

[0098] Scenario 3: When two pedals are connected, one for channel 1 and one for channel 2, the work interface of pedal channel 1 displays the type of handle connected to channel 1, and the work interface of pedal channel 2 displays the type of handle connected to channel 2. The icon of the work interface of foot pedal channel 1 may be displayed in blue; the indicator light on the handle may be displayed in blue, and the indicator light on the pedal may be displayed in blue; the icon of the work interface of foot pedal channel 2 may be displayed in orange; the indicator light on the handle may be displayed in orange, and the indicator light on the pedal may be displayed in orange;

[0099] Scenario 4: When the pedal is not connected (including wired and wireless), the interface displays that the pedal is not connected.

[0100] It should also be emphasized that a setting button can also be set on the host display screen. The user can click the setting button to switch the host to the wireless connection mode for Bluetooth matching. When the foot pedal channel 1 is successfully connected to the foot pedal wirelessly, the foot pedal indicator light can also display blue. When the foot pedal channel 2 is successfully connected to the foot pedal wirelessly, the foot pedal indicator light can also display orange. At the same time, the working interface of the corresponding foot pedal channel can also display the relevant content of the foot pedal. This embodiment will not go into details.

[0101] The host address stored in the foot pedal in this embodiment can be the address sent by the host when the foot pedal is connected to the host by wire. After the foot pedal enters the wireless connection mode, the stored host address can be obtained, and a connection request generated based on the host address can be sent to the host. After receiving the connection request, the host can establish a wireless connection with the foot pedal. Compared with the existing method that requires the user to manually pair the foot pedal with the host so that the foot pedal obtains the host address of the host, this embodiment can make the host send the address to the foot pedal for storage when the foot pedal is connected to the host by wire, and no user operation is required, which simplifies the operation process and improves the user experience.

[0102] Based on the above embodiment, the second embodiment of the wireless connection method of the present application is extracted, referring to Figure 4 , Figure 4 This is a flow chart of the second embodiment of the wireless connection method of the present application.

[0103] Considering that different pedals may have different travel distances, in order to facilitate host recognition, such as Figure 4 As shown, in this embodiment, before the step of obtaining and storing the host address sent by the host, the following step is further included:

[0104] Step S011: When power-on is detected, the pedal stroke is initially calibrated to obtain an initial calibration result.

[0105] It should be noted that the above initial calibration can be a calibration of the lower limit of the pedal, that is, a calibration when there is no pedaling. Figure 3 After powering on, the pedal itself can be initialized (i.e. Figure 3 After the initialization is completed, the pedal can calibrate the lower limit (i.e. Figure 3 The initial calibration result is obtained, and then the current power supply mode can be determined.

[0106] Step S012: perform secondary calibration on the pedal stroke to obtain a dynamic calibration result.

[0107] It is understandable that the above secondary calibration can be a calibration of the upper limit of the pedal, that is, the calibration when the pedal is stepped on to the upper limit. In actual use, when it is determined that the cable is powered, when the user steps on the pedal, the pedal can obtain the degree of stepping (i.e. Figure 3 The pedal value is obtained from the pedal stroke value, and it is detected whether the preset upper limit of the stroke is reached (the preset upper limit of the stroke can be the upper limit of the pedal stroke); when the preset upper limit of the stroke is reached, it can be said that the user has stepped to the bottom, and the pedal stroke is further calibrated (i.e. Figure 3 Dynamic calibration) is performed to obtain dynamic calibration results; when the preset travel limit is not reached, there is no need for secondary calibration.

[0108] After the above step of obtaining and storing the host address sent by the host, the method further includes:

[0109] Step S14: obtaining a current pedaling degree, and generating a pedal control signal according to the current pedaling degree, the initial calibration result and the dynamic calibration result;

[0110] Step S15: transmitting the pedal control signal to the host, so that the host performs a corresponding control operation according to the pedal control signal.

[0111] It should be understood that after obtaining the dynamic calibration result, the percentage corresponding to each pedal degree can be determined based on the initial calibration result and the dynamic calibration result, that is, the initial calibration result corresponds to the lower limit of the pedal stroke, and the dynamic calibration result corresponds to the upper limit of the pedal stroke. The percentage corresponding to each pedal degree can be determined based on the lower limit and the upper limit. Then, when the user steps on the pedal, the pedal can obtain the current degree of stepping, and generate a corresponding pedal control signal based on the percentage obtained by the previous calibration and transmit it to the host. After receiving the pedal control signal, the host can control the handle to perform the corresponding control operation according to the pedal control signal, so that the pedal can achieve stepless controllable adjustment, which is more conducive to the user to control the handle output according to needs.

[0112] Furthermore, in order to implement calibration in the wireless connection mode, in this embodiment, after the step of obtaining the stored host address, the following steps are further included:

[0113] Step S111: perform secondary calibration on the pedal stroke to obtain a dynamic calibration result.

[0114] It should be noted that when the pedal stroke is initially calibrated and the initial calibration result is obtained, the current power supply mode can be determined. If it is determined to be battery powered (i.e. Figure 3 When the battery is in the middle), it means that there is no wired connection between the pedal and the host, and the pedal enters the wireless connection mode.

[0115] After the pedal enters the wireless connection mode, it can be consistent with the wired connection mode. When the user steps on the pedal, the pedal can obtain the degree of stepping (i.e. Figure 3 The pedal value is obtained from the pedal stroke value, and it is detected whether the preset upper limit of the stroke is reached (the preset upper limit of the stroke can be the upper limit of the pedal stroke); when the preset upper limit of the stroke is reached, it can be said that the user has stepped to the bottom, and the pedal stroke is further calibrated (i.e. Figure 3 Dynamic calibration) is performed to obtain dynamic calibration results; when the preset travel limit is not reached, there is no need for secondary calibration.

[0116] After the step of sending the generated connection request to the host based on the host address, the method further includes:

[0117] Step S40: obtaining a current pedaling degree, and generating a pedal control signal according to the current pedaling degree, the initial calibration result and the dynamic calibration result;

[0118] Step S50: transmitting the pedal control signal to the host, so that the host performs a corresponding control operation according to the pedal control signal.

[0119] It is understandable that after obtaining the dynamic calibration result, the percentage corresponding to each pedal stepping degree can be determined based on the initial calibration result and the dynamic calibration result, that is, the initial calibration result corresponds to the lower limit of the pedal stroke, and the dynamic calibration result corresponds to the upper limit of the pedal stroke. The percentage corresponding to each stepping degree can be determined based on the lower limit and the upper limit. After establishing a wireless connection between the pedal and the host, when the user steps on the pedal, the pedal can obtain the current stepping degree, and generate a corresponding pedal control signal based on the percentage obtained by the previous calibration and transmit it to the host (i.e. Figure 3 After receiving the pedal control signal, the host can control the handle to perform corresponding control operations according to the pedal control signal, so that the pedal can be adjusted steplessly, which is more conducive to the user to control the handle output according to needs.

[0120] For example, when in use, the pedal can be initially calibrated without being stepped on to determine the pedal stroke lower limit and a preset stroke upper limit, and then the user's current pedaling degree can be detected in real time. When the current pedaling degree exceeds the preset stroke upper limit, it can be said that the pedal does not meet the user's needs under the current calibration, and then the pedal can be recalibrated according to the current pedaling degree to obtain the pedal stroke upper limit, and the pedal stroke upper limit replaces the previous preset stroke upper limit. Then, a new percentage can be determined for each pedaling degree based on the pedal stroke lower limit and the new pedal stroke upper limit, and then a new control signal is generated based on the percentage and the current pedaling degree and transmitted to the host, so that the host performs the corresponding control operation. There is no need for the user to perform manual calibration again, which is more conducive to the user controlling the handle output according to demand.

[0121] Furthermore, considering that a button is also provided on the foot pedal in this embodiment, when a wired connection is made, the foot pedal can transmit the button data (i.e. Figure 3 The key value obtained in the data is also returned to the host through the cable, so that the host performs the corresponding operation according to the key data. Similarly, when the wireless connection is used, the corresponding key data can also be sent to the host via Bluetooth, which is not described in detail in this embodiment.

[0122] Furthermore, considering that when the wireless connection is used, the power supply is provided by a cable, and when the user turns off the host but forgets to turn off the pedal, it may cause a waste of power. In this embodiment, after the step of transmitting the pedal control signal to the host, the following step is further included:

[0123] When the communication instruction sent by the host is not received, communication loss timing is performed;

[0124] When the timing result exceeds the preset time, the current state is switched to a low power consumption state.

[0125] It should be noted that the communication loss timing can be a timing to determine the disconnection with the host. In subsequent operation, since the host can generate and send a downlink instruction to the pedal at a certain preset time interval (e.g., 5 minutes), the pedal can detect whether it has received the downlink instruction from the host (i.e. Figure 3 If the data is not received, the pedal can start the communication loss timing (i.e. Figure 3 If the timing result does not exceed the preset time (i.e. 5 minutes above, that is, Figure 3 If the communication loss is greater than 5 minutes, the timing will continue; if the timing result exceeds the preset time, it means that the pedal has not received the downlink command from the host within 5 minutes and may be disconnected from the host, and then the pedal can switch the current state to a low power state (i.e. Figure 3 The low power consumption state may be a state where the battery stops supplying power to the pedal, or other states where power consumption is reduced, which are not limited in this embodiment;

[0126] If the downlink command sent by the host is received, it means that the connection with the host is normal at this time, and the pedal normally outputs the generated control signal to the host (i.e. Figure 3 The serial port Bluetooth data output) and clear the previously recorded communication loss timing (i.e. Figure 3 Clear the communication missing time in the command window) so that the timer can start again from 5 minutes if no downlink command is received.

[0127] In addition, to achieve the above purpose, the present application embodiment also provides a wireless connection method, referring to Figure 5 , Figure 5 This is a flow chart of the third embodiment of the wireless connection method of the present application.

[0128] like Figure 5 As shown, in this embodiment, the above method can be applied to a host of a surgical device, and the surgical device may include the foot pedal of the above embodiment, and the method includes:

[0129] Step S60: When the foot pedal is connected by wire, a host address is sent to the foot pedal;

[0130] Step S70: when detecting that the wireless connection mode has been entered, monitoring whether a connection request sent by the foot pedal is received, the connection request being a request sent by the foot pedal based on the stored host address when detecting that the wireless connection mode has been entered;

[0131] Step S80: upon receiving the connection request, establishing a wireless connection with the pedal according to the connection request.

[0132] In actual use, when the host is connected to the pedal, it can first send the host address stored in the host to the pedal, and then the user can disconnect the wired connection between the host and the pedal through the display screen of the host, and switch to the wireless connection mode. When the host enters the wireless connection mode, it can continuously monitor whether it has received the connection request sent by the pedal, if not, it continues to wait, and if so, it can establish a wireless connection with the pedal based on the connection request. Since the host address stored in the pedal in this embodiment is the host address sent by the host when the pedal is connected to the host by wire, the user does not need to manually pair the foot pedal with the host so that the foot pedal obtains the host address of the host, thereby simplifying the operation process and improving the user experience.

[0133] It should be emphasized that, since the above embodiments have described the specific process, the process of the host in this embodiment can refer to the above embodiments, and this embodiment will not elaborate on it.

[0134] Furthermore, in order to enable the pedal to obtain the host address of the host, in this embodiment, the above step S60 includes:

[0135] Step S061: When connected to the pedal by wire, a downlink instruction is generated and sent to the pedal, so that when the pedal receives the downlink instruction, it queries whether a host address has been stored, and when the host address is not stored, it obtains the host address carried in the downlink instruction and stores the host address.

[0136] In actual use, when the host is connected to the pedal by wire, the host can send a downlink instruction with its own host address to the pedal. When the pedal receives the downlink instruction, it can determine whether it has already stored the host address; if the host address is not stored, it can be said that the pedal is a "new pedal" at this time, and then the pedal can store the host address carried in the downlink instruction.

[0137] Furthermore, the above step S60 also includes:

[0138] Step S062: when the pedal is wiredly connected, a downlink instruction is generated and sent to the pedal, so that when the pedal receives the downlink instruction, it inquires whether a host address has been stored, and if a host address has been stored, it obtains the stored host address and feeds back the host address to the host through an uplink instruction;

[0139] Step S063: When it is determined that the actual host address does not match the fed-back host address and an update binding operation input by the user is received, the actual host address is sent so that the pedal acquires and stores the actual host address.

[0140] When the pedal currently stores a host address, the stored host address can be obtained and fed back to the host through the above-mentioned uplink instruction. After receiving the host address stored in the pedal, the host can determine whether it matches its actual host address;

[0141] When the host detects a match, it means that the binding relationship has not changed, and there is no need to send the actual host address to the pedal for storage again. The pedal can communicate with the host normally and transmit the control signal generated by the pedal to the host through the cable for related control operations;

[0142] When the host detects a mismatch, it may indicate that the host address previously stored in the pedal is not the host address of the host, or that the pedal was not wirelessly connected to the host before. The pedal is a "new pedal" for the host, and the binding relationship may need to be updated. In order to determine whether an update is needed, the host may display an inquiry window on the display screen, specifically asking the user whether to update. The user may click on the screen as needed. When the result clicked by the user is "do not update", it may indicate that the user hopes that the pedal may be temporarily used for the host at this time, and only needs to maintain the current wired connection communication. Then, the host may receive the user's input of the non-update binding operation, and the pedal does not adjust the stored host address.

[0143] When the result clicked by the user is "update", it means that the user hopes that the pedal may be used for the host for a long time, and then the host can generate a reset instruction to the pedal according to the update binding operation input by the user, and the host address can be set in the reset instruction; when the pedal receives the reset instruction, it can feed back its own pedal address to the host, so that the host can save the pedal address for subsequent wireless connection through the host; at the same time, the pedal can obtain the actual host address of the host carried in the reset instruction, and clear the previously stored host address, and save the actual host address of the host as the new host address to complete the reset, so as to obtain and store the actual host address and complete the update of the binding relationship. Then, after the pedal enters the wireless connection mode, it can directly connect to the host wirelessly according to the stored actual host address, without the need for manual operation by the user.

[0144] Since the above embodiments have described the specific process, the process of the host in this embodiment can refer to the above embodiments, and this embodiment will not elaborate on it.

[0145] Furthermore, considering that the host in this embodiment can support wired connection and wireless connection with the pedal, in order to determine which method is finally used as the control source, in this embodiment, after the step of establishing a wireless connection with the pedal according to the connection request, the following is further included:

[0146] Acquire the current signal source type of the pedal, and determine the initial control source according to the current signal source type;

[0147] Determining a final control source based on the initial control source according to a preset priority;

[0148] When the final control source is the foot pedal, a corresponding control operation is performed according to a pedal control signal generated by the foot pedal.

[0149] It should be noted that the above-mentioned signal source types may include wired signal source types and wireless signal source types, wherein the wired signal source type may correspond to a wired connection, and the wireless signal source type may correspond to a wireless connection.

[0150] Reference Figure 6 , Figure 6 FIG. 1 is a schematic diagram of determining a signal source of a host in the third embodiment of the wireless connection method of the present application. Figure 6 As shown, when the pedal 1 is connected to the host, the host can collect the signal of the pedal 1 (i.e. Figure 6 In the middle pedal 1 signal collection), first determine whether there is a wired signal (i.e. Figure 6If the signal exists, it means that the pedal is connected to the host by wire. The current signal source type of the pedal is the wired signal source type. The wired signal source type can be set as the highest priority, and then the pedal 1 can be determined as the input source (i.e. Figure 6 1 input source is set in the foot pedal 1 input source) as the above initial control source; when there is no wired signal, it is determined whether there is a wireless signal (i.e. Figure 6 If there is a wireless signal, it can be determined that the current signal source type is a wireless signal source type, and the AND gate (i.e. Figure 6 In the case of no wired connection, wireless is determined, and the wireless signal source type is the secondary priority. Similarly, pedal 1 can be determined as the input source as the initial control source mentioned above;

[0151] Similarly, the above method can also be used for the pedal 2, which will not be described in detail in this embodiment.

[0152] Taking into account that a handle can also be connected in this embodiment, the handle will also be provided with operation buttons, and in order to select one from the handle and the pedal as the final control source, after determining that pedal 1 is the input source, the final control source can be determined according to the above-mentioned preset priority, among which this embodiment can default to the preset priority that the pedal priority is higher than the handle priority.

[0153] like Figure 6 As shown, Figure 6 Shows 3 controllers connected to the host (i.e. Figure 6 The user clicks the display screen (i.e. Figure 6 The middle foreground output register) selects two of the three handles as handle control sources. This embodiment uses the selection of handle control source 1 and handle control source 2 for illustration.

[0154] After obtaining handle control source 1 and handle control source 2, the host can use the foot pedal as the final control source according to the preset priority. As another implementation, the user can click the display screen (i.e. Figure 6 In the control source type register, one is selected from handle control source 1 and foot pedal 1 as the final control source 1, and one is selected from handle control source 2 and foot pedal 2 as the final control source 2.

[0155] Furthermore, when the final control source determined is the foot pedal, the host can receive the pedal control signal generated by the foot pedal and perform related control operations, and the handle control is invalid at this time.

[0156] The surgical device further includes a handle, and after the step of determining the final control source according to the preset priority based on the initial control source, further includes:

[0157] When the final control source is the handle, a corresponding control operation is performed according to a handle control signal generated by the handle.

[0158] When the final control source determined is the handle, the host can receive the handle control signal generated by the handle and perform related control operations, and the foot control is invalid at this time.

[0159] In addition, to achieve the above purpose, this embodiment also provides a surgical device, referring to Figure 7 , Figure 7 This is a structural block diagram of the first embodiment of the surgical device of the present application.

[0164] The host address stored in the foot pedal in this embodiment can be the address sent by the host when the foot pedal is connected to the host by wire. After the foot pedal enters the wireless connection mode, the stored host address can be obtained, and a connection request generated based on the host address can be sent to the host. After receiving the connection request, the host can establish a wireless connection with the foot pedal. Compared with the existing method that requires the user to manually pair the foot pedal with the host so that the foot pedal obtains the host address of the host, this embodiment can make the host send the address to the foot pedal for storage when the foot pedal is connected to the host by wire, and no user operation is required, which simplifies the operation process and improves the user experience.

[0169] The host is further configured to send the actual host address when it is determined that the actual host address does not match the fed-back host address and when an update binding operation input by a user is received;

[0170] The pedal is also used to obtain and store the actual host address.

[0175] The host is also used to perform corresponding control operations according to the pedal control signal.

[0176] As an implementation mode, the pedal is also used to perform secondary calibration on the pedal stroke to obtain a dynamic calibration result;

[0177] The pedal is further used to obtain a current pedaling degree, and generate a pedal control signal according to the current pedaling degree, the initial calibration result and the dynamic calibration result;

[0178] The pedal is also used to transmit the pedal control signal to the host;

[0179] The host is also used to perform corresponding control operations according to the pedal control signal.

[0180] As an implementation mode, the pedal is also used to perform communication loss timing when the communication instruction sent by the host is not received; when the timing result exceeds a preset time, the current state is switched to a low power consumption state.

[0181] As an embodiment, the host is also used to obtain the current signal source type of the foot pedal, and determine the initial control source according to the current signal source type; determine the final control source according to a preset priority based on the initial control source; when the final control source is the foot pedal, perform corresponding control operations according to the pedal control signal generated by the foot pedal.

[0182] As an embodiment, the surgical device further includes a handle, and the host is further configured to perform a corresponding control operation according to a handle control signal generated by the handle when the final control source is the handle.
