[0052] The arm information acquisition module 22 includes a plurality of sensors for acquiring motion information of the joints of the robotic arm 12, such as position, velocity, acceleration, etc., and acquiring joint state information of the robotic arm 12, such as posture, etc.

It is worth noting that the data information about the surgical instrument 13 includes at least one of the following: the movement, type, configuration, and parameter version of the surgical instrument 13. The type of data information should be selected based on actual usage requirements and may include all or only one of the following, in any combination.

[0054] Among them, the serial port information of multiple arm information and instrument information is transferred out through the USB interface, which greatly reduces the number of wiring and simplifies the system wiring; the USB interface supports multi-channel serial port expansion, which can meet the needs of multi-instrument identification and multi-arm information transmission; it is worth mentioning that when the system starts, the host computer 25 reads the pre-stored arm information ID through the USB interface and initializes multiple serial port communication parameters to realize targeted data collection of the information of the robot arm 12 and ensure the accuracy of data collection.

[0055] Among them, the test module 24 is serially connected to the signal conversion module 21, that is, when the robot arm 12 and the instrument signals uploaded to the host computer 25 match, a signal can be sent to the test module 24 through the intermediate medium signal conversion module 21, so that the test module 24 can display in real time whether the information of the robot arm 12 and the instrument is accurate, thereby achieving the effect of self-verification and alarm display.

[0056] Exemplarily, there are multiple arm information acquisition modules 22 ; the multiple arm information acquisition modules 22 are connected to the signal conversion module 21 via one serial port.

[0058] Among them, the surgical robot includes a patient operating platform 1, and the patient operating platform 1 preferably includes three robotic arms 12; that is, the data information of the three robotic arms 12 is connected in parallel to form three lines and then transmitted to the signal conversion module 21 through one serial port information for transmission; when the host computer 25 transmits the control signal to the signal conversion module, the signal conversion module identifies the data information of one serial port signal through the ID reserved for the arm and transmits it to the corresponding arm information acquisition module 22, thereby realizing accurate and rapid identification and transmission of the arm information; the patient operating platform 1 also preferably includes four robotic arms 12; that is, the data information of the four robotic arms 12 is connected in parallel to form four lines and then transmitted to the signal conversion module 21 through one serial port information; when the host computer 25 transmits the control signal to the signal conversion module, the signal conversion module identifies the data information of one serial port signal through the ID reserved for the arm and transmits it to the corresponding arm information acquisition module 22, thereby realizing accurate and rapid identification and transmission of the arm information; it is worth mentioning that the ID of the arm information is pre-stored, and the identification and transmission of multiple arm information is realized through one serial port, thereby improving the efficiency and reliability of the information interaction system 2.

[0059] Exemplarily, there are a plurality of the device information acquisition modules 23 ; each of the device information acquisition modules 23 is connected to the serial port.

[0060] Specifically, the multiple device information acquisition modules 23 are connected to the signal conversion module 21 corresponding to one serial port respectively, so that the multiple device signals are connected in series with the signal conversion module 21 in a one-to-one correspondence, thereby improving the accuracy and reliability of system information transmission.

[0061] The surgical robot includes a patient operating platform 1, which preferably includes three robotic arms 12, and the ends of the three robotic arms 12 are each equipped with a surgical instrument 13; that is, the data information of the three surgical instruments 13 are respectively formed into three serial lines corresponding to each other and transmitted to the signal conversion module 21 for transmission; when the host computer 25 transmits the control signal to the signal conversion module, the signal conversion module transmits the three serial signals to the corresponding instrument information acquisition module 23 one by one, thereby realizing accurate and rapid transmission of the instrument information; the patient operating platform 1 also preferably includes four robotic arms 12, and the four robotic arms 12 are respectively equipped with surgical instruments ...; when the host computer 25 transmits the control signal to the signal conversion module, the signal conversion module transmits the three serial signals to the corresponding instrument information acquisition module 23 one by one, thereby realizing accurate and rapid transmission of the instrument information The end of the robotic arm 12 is equipped with a surgical instrument 13; that is, the data information of the four surgical instruments 13 are respectively corresponding to form four serial port lines and transmitted to the signal conversion module 21 for transmission; when the host computer 25 transmits the control signal to the signal conversion module, the signal conversion module transmits the four serial port signals one by one to the corresponding instrument information acquisition module 23, thereby realizing accurate and rapid transmission of instrument information; it is worth mentioning that since there are many types of surgical instruments 13, multiple serial ports are used to correspond to each surgical instrument 13 for collection, thereby ensuring the accuracy and reliability of the information interaction system 2.

[0062] In summary, when there are four robotic arms 12 and each end of the robotic arm 12 is equipped with an instrument, the signal conversion module 21 has six serial ports; one of the serial ports is connected to the four-arm arm information acquisition module 22 in parallel; the four serial ports are respectively connected to the information of the four surgical instruments 13 corresponding to the ends of the four robotic arms 12; and one serial port is connected to the test module 24, which is used to test whether the information collected by the arm information acquisition module 22 and the instrument information acquisition module 23 is accurate.

[0064] Specifically, the test module 24 includes a microcontroller 241 that can receive data information from the signal conversion module 21, that is, when the signal conversion module 21 sends a signal that the information of the robotic arm 12 is consistent with the corresponding ID robotic arm 12, the display component 242 sends a consistent signal; when the signal conversion module 21 sends a signal that the signal of the robotic arm 12 is inconsistent with the corresponding ID robotic arm 12, the display component 242 sends an inconsistent signal; when the signal conversion module 21 sends a signal that the information of the surgical instrument 13 is consistent with the corresponding surgical instrument 13, the display component 242 sends a consistent signal; when the signal conversion module 21 sends a signal that the information of the surgical instrument 13 is inconsistent with the corresponding surgical instrument 13, the display component 242 sends an inconsistent signal, so that the accuracy of data transmission can be intuitively understood in real time, thereby improving the usage performance.

[0065] Among them, the microcontroller 241 is preferably a programmable logic controller (PLC), which mainly includes a central processing unit, a storage and an input / output module, etc., and can better realize tasks such as information sampling, program execution and communication processing.

[0066] Exemplarily, the display element 242 is a first display light; the first display light has at least two status displays.

[0067] Specifically, whether the information of the robot arm 12 and the surgical instrument 13 obtained by the signal conversion module 21 is accurate is judged by at least two states of the first display light, thereby improving the accuracy and reliability of the overall system.

[0068] Exemplarily, the signal conversion module 21 further includes a power supply input port and a power conversion unit; the power supply input port can introduce an external power supply, and the power conversion unit can transform the external power supply introduced by the power supply input port to a preset voltage value.

[0069] Specifically, the power input port introduces an external power source, and the power conversion unit reduces the voltage of the introduced external power source to a preset voltage so as to provide energy to the signal conversion module 21 .

[0070] The external power supply voltage is introduced through the power input port, and the introduced voltage is changed in voltage value through the power conversion unit to meet various actual voltage value requirements.

[0071] For example, the external power supply voltage introduced by the power input port is 24 volts, and the programming voltage requirement of the signal conversion module 21 is 12 volts. At this time, the power conversion unit reduces the 24 volt external power supply voltage to 12 volts to provide energy to the signal conversion module 21.

[0072] Exemplarily, the arm information acquisition module 22 and / or the instrument information acquisition module 23 are connected to the serial port via a one-line protocol.

[0073] Specifically, the arm information acquisition module 22 and the instrument information acquisition module 23 are both connected to the above serial port through a one-line protocol, so that communication and power supply can be achieved with a single connection line, supporting bus topology and communication with multiple devices.

[0074] Exemplarily, the signal conversion module 21 further includes a second display light 215 ; the second display light 215 is used to display the working status of the signal conversion module 21 .

[0075] Specifically, the working status of the signal conversion module 21 is displayed by the second display light 215; when the signal conversion module 21 is in a normal working state, the second display light 215 displays green; when the signal conversion module 21 is in an abnormal working state, the second display light 215 displays red; the working status of the signal adapter module can be intuitively known through the second display light 215, thereby increasing the use effect.

[0084] Specifically, the top of the column 11 of the patient operating platform 1 is connected to the head end of the robotic arm 12, and the end of the robotic arm 12 is connected to the surgical instrument 13. The surgical instrument 13 is used to directly execute the instructions of the doctor's operating platform to perform surgical operations; when the patient operating platform 1 is in working state, the arm information acquisition module 22 installed on the robotic arm 12 collects data information of the robotic arm 12, and the instrument information acquisition module 23 installed on the surgical instrument 13 collects data information of the surgical instrument 13, and transmits the collected data information to the signal conversion module 21 in a serial port manner through a one-line protocol.
