[0056] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings.

In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and therefore their description will be omitted.

[0057] Combination Figures 1 to 34 As shown, according to a specific embodiment of this application, a control system for an electric stapler is provided.

[0058] Specifically, such as Figure 1 As shown, the control system of the electric stapler includes a control unit and an output unit. The control unit includes at least a control module, and the signal input interface of the control module is electrically connected to the operation switch of the electric stapler. The output unit includes an output selection module, a first output module, and a second output module. The first output module is used to drive the actuator M1 of the electric stapler to operate, and the second output module is used to drive the bending motor M2 of the electric stapler to operate. The signal input interface of the output selection module is electrically connected to the output interface of the control module, and the signal output interface of the output selection module is electrically connected to the signal input interfaces of the first output module and the second output module. The output selection module is used to drive either the first output module or the second output module to output a signal, thereby driving either the actuator M1 or the bending motor M2 to operate.

[0059] The technical solution of this embodiment includes a control unit and an output unit in the control system of the electric stapler. The control unit includes a control module connected to an operating switch. After a user issues an operation command to the operating switch, the control module can recognize the operation command and control the output unit to perform the corresponding operation. The output unit includes an output selection module, a first output module, and a second output module. The first output module drives a generator M1 to control the forward and backward movement of the electric stapler, and the second output module drives a bending motor M2 to control the left and right bending of the electric stapler. The control module can transmit the operation command to the output selection module to select either the first or second output module for the electric stapler operation. Thus, the control system of the electric stapler, combined with the control unit and the output unit, can achieve various complex functions and intelligent operation. Compared with the prior art, which uses simple circuits to control the opening and closing of relay switches to control the connection and disconnection of motors, the technical solution in this embodiment uses multiple output modules for motor drive selection and independent motor drive control, resulting in higher motor control precision, more efficient and intelligent motor drive, and reduced noise in the control and drive process.

[0060] It should be noted that the operating switch is manually operated and can input various function commands. The operating switch includes left turn switch, right turn switch, switching switch, forward switch, return switch, stop switch and other function operation selection. The operating switch and the control system of the electric manipulator realize the multiple functions of the operating switch through circuit control. In order to increase the intelligence of operation, the control circuit of the control system can be improved. For example, the return switch and stop switch can be set to automatic trigger mode. When the return button on the generator M1 touches the trigger return switch on the control board, the return action is automatically started. The groove on the connecting rod of the generator M1 cooperates with the stop switch on the control board so that when the stop switch is opened, the return stops. Thus, the intelligent and automatic triggering of the return switch and stop switch is realized.

[0061] In one embodiment of this application, Figure 2 The control chip for the control module. Figures 3 to 8 This is the circuit diagram of the control module. The control module uses an MCU (Microcontroller Unit) as the chip to control and process the entire control system, such as... Figure 2 As shown, the MCU chip has multiple pins for connecting to components in the circuit to process operation commands and control the output commands of the output module. For example, Figure 3The circuit is connected to the SWCLK (Single Wire Clock) pin and SWDIO (Single Wire Data I / O) pin of the chip to debug and test the MCU and ensure normal interaction between the chip and the target device. Figure 4 The circuit is connected to the BOOT0 pin of the chip and is used to select the boot mode after downloading the debug program.

[0062] Specifically, the first output module includes a first drive module and a first switch module. The signal input interface of the first drive module is electrically connected to the signal output interface of the output selection module; the signal input interface of the first switch module is electrically connected to the signal output interface of the first drive module. The first drive module inputs a first drive signal to the first switch module, which adjusts the switching state of the first switch module, thereby adjusting the first operating mode of the actuator M1. The first operating mode includes at least a forward operating mode and a backward operating mode. After receiving the instruction from the output selection module, the first output module transmits the operation instruction to the first drive module. The first drive module controls the start / stop state of the actuator M1 through the first switch module. Simultaneously, when the first switch module controls the actuator M1 to start, it can also output the first operating mode, which controls the actuator M1 to perform forward or backward movements. After the output selection module selects the first output module, the first drive module and the first switch module work together to realize the start of the actuator M1 and its forward and backward operating states, thus realizing the cutting function of the electric stapler.

[0063] It should be noted that the output selection module, the first drive module, and the first switch module all contain chip structures, such as... Figure 9 , Figure 13 As shown, the output selection module includes two output selection chips, U13 and U14. U13 and U14 use an FSUSB30UMX controller for data transmission and storage. U13 and U14 can simulate the switch function of the output selection module, i.e., to switch between the first and second output modules; for example... Figure 10 , Figure 11 As shown, the first drive module also includes two drive chips, U1 and U4. U1 and U4 can amplify and selectively conduct the received high-side or low-side signals, and then send the signals to the first switching module. U1 and U4 use IR2101STRPBF integrated circuit (IC) chips to provide high current drive capability and amplify and process the drive signals; as shown... Figure 12As shown, the first switching module includes two switching control chips, U2 and U3. After receiving the drive signals from U1 and U4, U2 and U3 control the generator M1 to move forward or backward. U2 and U3 use BUK9K30-80EX MOSFETs to stably limit the output parameters of the generator M1 to ensure the stability of the generator M1's operation.

[0064] In this embodiment, the logic and circuit structure of the output selection module for selecting the first output module to control the generator M1 is as follows: The MCU sends a low-level signal to U13 and U14 through the M1 / M2 SEL pin. U13 and U14 then select PWM1_1, PWM2_1, PWM3_1, and PWM4_1 for output, and send the PWM signal to the driver chips U1 and U4. U1 and U4 output the amplified high-end signal and low-end signal to U2 and U3. When both the high-end signal HO1 and the low-end signal LO2 are turned on, the generator M1 can rotate forward. When both the high-end signal HO2 and the low-end signal LO1 are turned on, the generator M1 can rotate in reverse.

[0065] Furthermore, the second output module includes a second drive module and a second switch module. The signal input interface of the second drive module is electrically connected to the signal output interface of the output selection module; the signal input interface of the second switch module is electrically connected to the signal output interface of the second drive module. The second drive module inputs a second drive signal to the second switch module, which adjusts the switching state of the second switch module, thereby adjusting the second operating mode of the bending motor M2. The second operating mode includes at least a left-turning mode, a right-turning mode, and a return-to-center mode. After receiving the corresponding instruction from the output selection module, the second output module transmits the operation instruction to the second drive module. The second drive module controls the bending motor M2 to perform left-turning or right-turning actions through the second switch module. After the output selection module selects the second output module, the second drive module and the second switch module work together to start the bending motor M2 and enable its left-turning and right-turning operating states, realizing the multi-angle, directional cutting function of the electric stapler.

[0066] It should be noted that the second drive module and the second switch module also contain chip structures, such as... Figure 14 , Figure 15 As shown, the second drive module includes two drive chips, U5 and U8. U5 and U8 amplify and selectively conduct the received high-side or low-side signals, then transmit the signals to the second switching module. U5 and U8 use the IR2101STRPBF integrated circuit (IC) chip to provide high current drive capability and amplify and process the drive signal; as shown... Figure 16As shown, the second switch module includes two switch control chips, U6 and U7. After receiving the drive signals from U5 and U8, U6 and U7 control the bending motor M2 to make left or right turns. U6 and U7 use BUK9K30-80EX MOSFETs to stably limit the output parameters of the bending motor M2 to ensure the stability of the bending motor M2's operation.

[0067] In this embodiment, the logic and circuit construction principle of the output selection module in selecting the second output module to control the bending motor M2 are similar to the logic of the first output module controlling the generator M1. The MCU sends a high-level signal to U13 and U14 through the SEL pin of M1 / M2. U13 and U14 then select PWM1_2, PWM2_2, PWM3_2, and PWM4_2 outputs, and send the high-level signal to the driver chips U5 and U8. U5 and U8 output the amplified high-end signal and low-end signal to the field-effect transistors U6 and U7, thereby realizing the forward rotation, reverse rotation, and return-to-center control of the bending motor M2.

[0068] It should be noted that in this embodiment, U2, U3, U6, and U7 can also use other types of MOSFET chips, and are not limited to the chip selections mentioned above. Depending on actual needs, the second switching module and the first switching module can also use other switching devices, such as IGBT, JFET, bipolar transistor (BJT), thyristor (SCR), transistor array, integrated circuit, etc.

[0069] Furthermore, the control system also includes a bending limit module. The signal input interface of the bending limit module is electrically connected to the bending limit switch of the electric stapler, and the signal output interface of the bending limit module is electrically connected to the signal input interface of the control module. The bending limit module is used to detect the on / off state of the bending limit switch and send a bending limit status signal to the control module. The bending limit module limits the left and right bending operations of the electric stapler. When the generator M1 fires forward and backward, the forward limit is controlled by the retract button on the electric stapler, and the retracting limit is controlled by retracting to the groove of the firing lever.

[0070] In this embodiment, the bending limiting module is essentially a circuit board with solder pads, such as... Figure 17 As shown, Figure 17 The circuit structure of the circuit board is described, and the circuit board is connected to the MCU via wiring, specifically to the R_LIMIT, L / R_DELAY_2S, and L_LIMIT pins on the MCU, as shown below. Figure 18 As shown, Figure 18These are the pads attached to the circuit board. The terminals A, A1, B, B1, C, and C1 on the pads are the switch conduction points. The working principle is as follows: when the bending rod on the bending control module bends, it will drive the ejector pin. When the ejector pin conducts AA1, it is the left limit; when the ejector pin conducts BB1, it is the center return; and when the ejector pin conducts CC1, it is the right limit.

[0071] Furthermore, the control system also includes a power detection module. The signal output interface of the power detection module is electrically connected to the signal input interface of the control module. The power detection module is used to detect the battery level of the electric anastomosis device. Connecting the power monitoring module to the MCU enables the battery level detection and feedback function of the electric anastomosis device. Figure 19 As shown, Figure 19 The circuit for the power detection module is connected to the VIN_DETE pin of the MCU. Resistors R34 and R41 in this circuit act as a voltage divider. Its working principle is as follows: by feeding back different voltage values ​​to the MCU, the MCU can determine the actual voltage value, as well as whether power can be supplied to the motor, and take appropriate action. In this embodiment, the control system, through the inclusion of the power detection module, adds a power-off protection function in case of abnormalities in the electric stapler, making the use of the electric stapler safer.

[0072] Furthermore, the control system also includes an alarm module. The signal output interface of the alarm module is electrically connected to the alarm of the electric stapler, and the signal input interface of the alarm module is electrically connected to the signal output interface of the control module. The alarm module is used to control the alarm to emit an alarm signal. The alarm module has multiple warning functions; for example, it can alert the user when the motor is about to retract, and it can also indicate the remaining number of operations for the electric stapler, thus allowing the operator to be aware of the motor's operating status in a timely manner and avoiding accidental injury and subsequent impact on use.

[0073] Optionally, the warning module can also alert staff to low battery status and abnormal battery status of the electric stapler in the form of an alarm, or provide feedback to staff on the remaining battery status during normal operation in the form of an indication or prompt, so as to facilitate staff to make an estimate and judgment on the use of the electric stapler, thus realizing the intelligent battery feedback function.

[0074] Specifically, the warning system includes an audible warning device and multiple illuminated warning devices. The warning module includes an audible control circuit and an illuminated control circuit. The audible control circuit includes at least an audible control switch, which is connected in series with the audible warning device. When the audible control switch is turned on, the audible warning device emits an audible warning signal. There are multiple illuminated control circuits, each corresponding to an illuminated warning device. Each illuminated control circuit includes an illuminated control switch, and when the illuminated control switch is turned on, the illuminated warning device in that circuit emits an illuminated warning signal. For example... Figure 20 As shown, Figure 20 This is the circuit diagram for the sound control of the audible alarm. The audible alarm is used to issue a warning sound to alert the operator when the electric stapler retracts (i.e., to notify the operator that the electric stapler has begun to retract). Figure 21 As shown, Figure 21 This is a circuit diagram for the lighting control of a light warning device. The light warning device is divided into multi-level light warnings, using different light colors to indicate the number of times the electric stapler has been used or the remaining number of uses. The light control circuit is divided into multiple circuit loops, and multiple circuit loops can control different light warning devices to work.

[0075] In this embodiment, the audible alarm uses a buzzer, which works by sending a high-level signal to the sound control circuit via the MCU's BUZZER pin, causing... Figure 20 Q3 in the circuit is turned on, which causes the buzzer H1 to emit a sound.

[0076] In another embodiment of this application, the light warning device uses three different colored LEDs, and its working principle is as follows: it is controlled by the LED_RED, LED_GREEN, and LED_ORANGE pins of the MCU respectively. Figure 21 The conduction of Q1, Q2, and Q4 in the LED controls the LED to emit different colors of light or to flash different colors of light to indicate different usage times or remaining operation times.

[0077] Furthermore, the control system also includes a power management module, which is located at the power output terminal of the electric stapler. The power management module is used to regulate the power output of the electric stapler, and its signal input interface is electrically connected to the signal output interface of the control module. By incorporating the power management module into the control system, intelligent power management of the electric stapler can be achieved, resulting in energy savings, power system optimization, extended battery life, and improved equipment reliability. It can also be used to design circuits to implement various intelligent functions such as intelligent sleep / wake-up.

[0078] In this embodiment, the power management module includes multiple smart chips U10, U11, and U12, such as... Figure 22As shown, U10 can realize the power supply control output and overcurrent and overvoltage monitoring and control, and realize control together with the MCU. U11 and U12 can realize level conversion. U10 uses TPS54531DDA converter, which can provide stable and efficient power management control. U12 and U11 use REG1117 voltage regulator to adjust the output to a more stable voltage value.

[0079] Specifically, the power management module includes a voltage conversion circuit and a power protection circuit. The voltage conversion circuit converts the power output voltage to the target voltage; the power protection circuit cuts off the power output when the power output is in an abnormal state, which includes at least overcurrent, overvoltage, and undervoltage states. The power protection circuit is controlled by U10, such as... Figure 22 As shown, the output voltage control VOUT = 0.8(R16 / R40+1). When the abnormal state is undervoltage, that is, when the voltage is detected to be lower than a certain value, the output of chip U10 can be interrupted through the EN pin. When the abnormal state is overvoltage, that is, when the voltage of the VSENSE pin is higher than the internal threshold voltage, the MOSFET inside the chip is turned off, thereby stopping the circuit output. When the voltage of the VSENSE pin is lower than the internal threshold voltage, the MOSFET is turned on again, thereby achieving the purpose of protecting the circuit. When the abnormal state is overcurrent, the switching current and the voltage of the COMP pin are compared in each cycle. When the peak value of the inductor current intersects with the voltage of the COMP pin, the high-level switch is turned off. The voltage conversion circuit is controlled by U12 and U11 to realize the level conversion. In this embodiment, U12 converts 12V to +5V, and U11 converts 5V to +3.3V.

[0080] Furthermore, the control system includes a main control board 1 and a bending limit plate 4. The main control board 1 is equipped with a control unit and an output unit; the bending limit plate 4 is equipped with a bending limit module, and the signal output interface of the bending limit module is electrically connected to the control module of the control unit through a connecting signal line; wherein, the bending limit plate 4 is equipped with multiple sets of limit switch terminals, and when any set of limit switch terminals is turned on, the signal output interface of the bending limit module outputs the corresponding bending limit status signal. The connection circuit between the bending limit plate 4 and the MCU chip of the main control board 1 is as follows. Figures 23 to 29 As shown, Figures 23 to 29 The circuit diagram showing the specific connection of the limit switch terminals when the bending limit plate 4 controls the bending motor M2 is shown, for example, as follows: Figure 23 As shown, Figure 23 The circuits in the circuit are connected to the L_limit, L / R_Delay_2s, and R_limit pins of the MCU respectively to realize the left limit, center return, and right limit of the bending motor M2 by the bending limit module; for example Figure 24 As shown, Figure 24The circuit is connected to the M1 / M2_SWITCH pin of the MCU to realize the control switching between the generator M1 and the bending motor M2. That is, when the generator M1 is working, the bending motor M2 is not allowed to work, and when the bending motor M2 is working, the generator M1 is not allowed to work.

[0081] Specifically, the main control board 1 has two sides, such as... Figure 30 , Figure 31 As shown, Figure 30 The front of the main control board 1 Figure 31 On the reverse side of the main control board 1, 1-1 is the bending limit connection end, 1-2 is the speaker, 1-3 is the status indicator light, 1-4 is the main power switch, 1-7 is the generator start button, 1-8 is the right bend button, 1-9 is the motor switch, 1-10 is the left bend switch, 1-11 is the start and retract switch, and 1-12 is the stop switch.

[0082] In this embodiment, the connection and interaction between the main control board 1 and the electric stapler are as follows:

[0083] The bending limit connection terminal 1-1 on the main control board 1 is connected to the bending limit plate 4 of the electric stapler. The AA1 switch terminal on the bending limit plate 4 is connected to the right limit switch, the BB1 ​​switch terminal on the bending limit plate 4 is connected to the return switch, and the CC1 switch terminal on the bending limit plate 4 is connected to the left limit switch. The speaker 1-2 is a buzzer, which serves as a warning sound. The status indicator 1-3 is an LED tri-color light, which indicates the power status. 1-4 is the main power switch. 1-5 on the main control board 1 is connected to the bending motor M2 of the electric stapler, which controls the forward and reverse rotation of the bending motor M2, thereby controlling the left bending, return, and right bending of the electric stapler. 1-6 on the main control board 1 is connected to the generator M1 of the electric stapler, which controls the forward and reverse rotation of the generator M1, thereby controlling the forward movement of the electric stapler. The electric anastomosis device has several control mechanisms: a retraction switch and a retraction switch; a generator button 1-7 connected to the generator trigger button, which, when triggered, causes the generator to rotate forward; a right-turn button 1-8 connected to the electric anastomosis device, which, when triggered, causes the retraction motor M2 to rotate forward; a motor switching switch 1-9 connected to the electric anastomosis device, which, when closed, allows the generator M1 to operate, and when open, allows the retraction motor M2 to operate, thus controlling and avoiding the risk of both motors operating simultaneously; a left-turn switch 1-10 connected to the left-turn button of the electric anastomosis device, which, when triggered, causes the retraction motor M2 to rotate in reverse; when the retraction button of the electric anastomosis device touches the retraction switch 1-11, the connecting rod of the electric anastomosis device automatically retracts; and a stop switch connected to the connecting rod of the electric anastomosis device, which has a groove that mates with the stop switch. When the connecting rod retracts and the stop switch is in the groove, the generator M1 of the electric anastomosis device stops rotating in reverse.

[0084] The logic for automatically stopping and reversing the generator M1 and its connection with the MCU are as follows: the RETURN_SWTICH pin of the MCU is connected to the SW2 back switch, and the STOP_SWTICH pin of the MCU is connected to the SW3 stop switch. The logic function implemented by the above connection is as follows: when the trigger switch is pressed, the generator M1 moves forward with the connecting rod, and SW3 is triggered at the same time. When the return switch is touched, the connecting rod retracts. When SW3 retracts to the groove of the connecting rod, the generator M1 stops rotating.
