Description

Technical Field

[0001] The present disclosure relates to the technical field of medical equipment, and in particular to a pneumoperitoneum system and a method for controlling the pneumoperitoneum system. Background Art

[0002] During laparoscopic surgery, it is necessary to create a surgical space in the abdominal cavity, which requires infusing gas (such as CO2) into the abdominal cavity to raise the anterior abdominal wall so as to have a good field of vision and facilitate the operation of instruments. The pneumoperitoneum machine is a device for creating and maintaining pneumoperitoneum during laparoscopic surgery.

[0003] In the related art, during the use of the insufflator, it is necessary to supply gas to the target abdominal cavity according to the target abdominal cavity pressure. However, since the insufflator cannot take into account both pressure measurement and gas supply, it is impossible to accurately detect the target abdominal cavity pressure when supplying gas to the target abdominal cavity. Therefore, it is necessary to stop supplying gas to the target abdominal cavity when detecting the target abdominal cavity pressure. However, stopping supplying gas to the target abdominal cavity will affect the efficiency of gas leakage and gas replenishment, thereby causing the pressure in the target abdominal cavity to be unstable, affecting the surgical operation.

[0044] Combined with the following Figures 1 to 5 The pneumoperitoneum system, the pneumoperitoneum system control method, etc. disclosed in the present invention are described in detail.

[0045] Figure 1 Schematic diagram of application scenarios of the pneumoperitoneum machine system of some embodiments of the present disclosure. Figure 1 The pneumoperitoneum system 1000 provided by the present disclosure includes two pneumoperitoneum machines 1100 and a control system 1200. The two pneumoperitoneum machines 1100 can be connected to the same target abdominal cavity. The control system 1200 is used to determine the first pneumoperitoneum machine 1102 and the second pneumoperitoneum machine 1104 of the two pneumoperitoneum machines 1100, and control the first pneumoperitoneum machine 1102 to obtain the target abdominal cavity pressure, and control the second pneumoperitoneum machine 1104 to provide gas to the target abdominal cavity according to the target abdominal cavity pressure.

[0046] The insufflator system 1000 of the disclosed embodiment first determines the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, and then obtains the target abdominal cavity pressure through the first insufflator 1102, and supplies gas to the target abdominal cavity according to the target abdominal cavity pressure through the second insufflator 1104. That is, obtaining the target abdominal cavity pressure and supplying gas to the target abdominal cavity are completed by different insufflators 1100, and gas can be continuously supplied to the target abdominal cavity while obtaining the accurate target abdominal cavity pressure. There is no need to stop supplying gas to the target abdominal cavity in order to obtain the accurate target abdominal cavity pressure, which is beneficial to improving the efficiency of gas replenishment and gas leakage, stably maintaining the pressure in the target abdominal cavity, and facilitating surgical operations.

[0047] It is understandable that during laparoscopic surgery, smoke will be generated when using high-frequency electrocoagulation devices such as electrocautery, and this smoke will affect the surgical field of view. Therefore, negative pressure suction equipment is often used to remove smoke from the surgical area. If the supply of gas to the target abdominal cavity is stopped in order to obtain the target abdominal cavity pressure during the use of the negative pressure suction equipment, the target abdominal cavity pressure will drop rapidly, thereby affecting the surgical operation. However, the pneumoperitoneum machine system 1000 of the embodiment of the present disclosure does not need to stop supplying gas to the target abdominal cavity in order to obtain the target abdominal cavity pressure. Therefore, the negative pressure suction equipment can be used normally and the target abdominal cavity pressure will not be affected.

[0048] Optionally, the structures of the two insufflators 1100 in the insufflator system 1000 may be completely identical or partially identical, which is not limited here.

[0049] Optionally, the control system 1200 may be configured outside the two pneumoperitoneum machines 1100 , or may be configured in any one or both of the two pneumoperitoneum machines 1100 , which is not limited here.

[0050] For example, when supplying gas to the target abdominal cavity according to the target abdominal cavity pressure, if the target abdominal cavity pressure is greater than the target pressure threshold, the gas supply flow rate to the target abdominal cavity is reduced; if the target abdominal cavity pressure is less than the target pressure threshold, the gas supply flow rate to the target abdominal cavity is increased; if the target abdominal cavity pressure is equal to the target pressure threshold, the gas supply flow rate to the target abdominal cavity is kept unchanged. In this way, gas is dynamically supplied to the target abdominal cavity according to the target abdominal cavity pressure.

[0051] In one example, the target abdominal cavity is the abdominal cavity of a patient, and the gas is CO2 gas.

[0052] In some embodiments, the first pneumoperitoneum machine 1102 includes a first controller and a first communication module connected to the first controller. The first controller obtains the target abdominal pressure and sends the target abdominal pressure through the first communication module. The second pneumoperitoneum machine 1104 includes a second controller and a second communication module connected to the second controller. The second communication module can be communicatively connected with the first communication module, and the second controller can receive the target abdominal pressure sent by the first controller via the second communication module.

[0053] In this way, the first insufflator 1102 can obtain the target abdominal cavity pressure, and the second insufflator 1104 can obtain the target abdominal cavity pressure by communicating with the first insufflator 1102. By cooperating with each other, the target intra-abdominal pressure can be stably maintained, which is beneficial to improving the efficiency of gas replenishment and air leakage and facilitating surgical operations.

[0054] In some embodiments, both insufflators 1100 include a pressure detection module and an air supply module. After determining the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, the control system 1200 is also used to: control the pressure detection module of the first insufflator 1102 to work while the air supply module does not work, and control the air supply module of the second insufflator 1104 to work while the pressure detection module does not work.

[0055] In this way, the first insufflator 1102 and the second insufflator 1104 have clear division of labor and cooperate with each other to stably maintain the pressure in the target abdominal cavity, which is beneficial to improving the efficiency of gas replenishment and air leakage and facilitating surgical operations.

[0056] Exemplarily, the pressure detection module can detect the target abdominal cavity pressure, and the gas supply module can provide gas to the target abdominal cavity.

[0057] In some embodiments, the control system 1200 includes a first controller and a second controller. The first controller is configured in one of the two insufflator machines 1100. The second controller is configured in the other of the two insufflator machines 1100.

[0058] In this way, the two insufflators 1100 can be controlled by the controller of the insufflator 1100 itself, which is helpful to improve the control efficiency.

[0059] Exemplarily, one of the first controller and the second controller can determine the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, and control the first insufflator 1102 to obtain the target abdominal cavity pressure, and control the second insufflator 1104 to provide gas to the target abdominal cavity according to the target abdominal cavity pressure.

[0060] In one example, two insufflators 1100 are respectively configured with a communication module 1300, so that the first controller can communicate with the second controller. Even if the first controller and the second controller are not on the same insufflator 1100, one of the first controller and the second controller can indirectly control the insufflator 1100 where the other of the first controller and the second controller is located by communicating between the two controllers.

[0061] In one example, the communication module 1300 configured for the two pneumoperitoneum machines 1100 is a communication interface, and the communication interface can be connected to the communication line 1400, so that the first controller and the second controller can be connected in wired communication through the communication line 1400.

[0062] In another example, the communication module 1300 configured for the two pneumoperitoneum machines 1100 is a wireless communication module, and thus the first controller and the second controller can be wirelessly connected via the wireless communication module.

[0063] In some embodiments, the two insufflators 1100 are respectively provided with a detection component, and the detection component can send a gas source connection signal to the control system 1200 when the gas inlet of the insufflator 1100 is connected to the gas source. When the control system 1200 determines the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, it is specifically used to: when one of the detection components sends a gas source connection signal and the other detection component does not send a gas source connection signal, the insufflator 1100 where the detection component that sends the gas source connection signal is located is used as the second insufflator 1104, and the insufflator 1100 where the detection component that does not send the gas source connection signal is located is used as the first insufflator 1102.

[0064] In this way, the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100 can be accurately determined based on the gas source connection signals sent by the two detection components.

[0065] Optionally, the detection component may include a pressure switch or a third pressure sensor. The detection component may be arranged at the air inlet of the pneumoperitoneum machine 1100 .

[0066] Exemplarily, when the high-pressure tube supplying the gas source is connected to the gas inlet of the insufflator 1100, the high-pressure tube can touch the pressure switch or the third pressure sensor, thereby triggering the pressure switch or the third pressure sensor to generate a gas source connection signal, and send the gas source connection signal to the control system 1200. The gas source connection signal is used to indicate that the corresponding insufflator 1100 is connected to the gas source. When the high-pressure tube supplying the gas source is not connected to the gas inlet of the insufflator 1100, the control system 1200 cannot receive the gas source connection signal.

[0067] Exemplarily, the third pressure sensor includes an air pressure sensor. When the high-pressure tube supplying the air source is connected to the air inlet of the pneumoperitoneum machine 1100, the high-pressure air source in the high-pressure tube can trigger the air pressure sensor to generate an air source connection signal and send the air source connection signal to the control system 1200.

[0068] In one example, the control system 1200 includes the aforementioned first controller and the second controller, the detection component includes the first detection component and the second detection component, the first detection component is connected to the first controller, and the second detection component is connected to the second controller. When determining the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, the first controller determines whether the gas source connection signal sent by the first detection component is received, and sends the determination result to the second controller, the second controller determines whether the gas source connection signal sent by the second detection component is received, and when one of the first detection component and the second detection component sends the gas source connection signal and the other of the first detection component and the second detection component does not send the gas source connection signal, the insufflator 1100 where the detection component that sends the gas source connection signal is located is used as the second insufflator 1104, and the insufflator 1100 where the detection component that does not send the gas source connection signal is located is used as the first insufflator 1102.

[0069] In some embodiments, the two insufflators 1100 are respectively provided with a detection component, and the detection component can send a gas source connection signal to the control system 1200 when the gas inlet of the insufflator 1100 is connected to the gas source. When the control system 1200 determines the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, it is specifically used to: when one of the detection components sends a gas source connection signal, the insufflator 1100 where the detection component that sends the gas source connection signal is located is used as the second insufflator 1104, and the other of the two insufflators 1100 is directly used as the first insufflator 1102.

[0070] In this way, the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100 can be quickly determined based on the gas source connection signal sent by a detection component.

[0071] Exemplarily, the implementation method of the detection component of this embodiment is the same as the implementation method of the detection component of the above-mentioned embodiment, which is not repeated here.

[0072] In one example, the control system 1200 includes the aforementioned first controller and the second controller, the detection component includes the first detection component and the second detection component, the first detection component is connected to the first controller, and the second detection component is connected to the second controller. When determining the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, the first controller determines whether the gas source connection signal sent by the first detection component is received, and sends the determination result to the second controller, and the second controller determines whether the gas source connection signal sent by the second detection component is received. If the second controller determines that one of the first detection component and the second detection component has sent an gas source connection signal, it will no longer determine whether the other detection component of the first detection component and the second detection component has sent an gas source connection signal, but directly use the insufflator 1100 where the detection component that sent the gas source connection signal is located as the second insufflator 1104, and use the other of the two insufflators 1100 as the first insufflator 1102.

[0073] In some embodiments, the insufflator system 1000 also includes a prompt component, and the control system 1200 is also used for: when both detection components have not sent an air source connection signal, a gas source connection prompt is given through the prompt component, and the gas source connection prompt is used to indicate that any one of the two insufflator machines 1100 is connected to the air source; when both detection components send an air source connection signal, a gas source disconnection prompt is given through the prompt component, and the gas source disconnection prompt is used to indicate that any one of the two insufflator machines 1100 is disconnected from the air source.

[0074] In this way, when both detection components send or do not send the gas source connection signal, it is possible to ensure through prompts that one of the two insufflators 1100 is connected to the gas source and the other of the two insufflators 1100 is disconnected from the gas source, which is facilitating the subsequent accurate determination of the first insufflator 1102 and the second insufflator 1104.

[0075] Exemplarily, the prompt component may include one or more of a display screen and a speaker.

[0076] Exemplarily, after providing a gas source connection prompt or a gas source disconnection prompt, the control system 1200 continues to monitor the gas source connection status of the two insufflators 1100 until the first insufflator 1102 and the second insufflator 1104 are determined.

[0077] It is understandable that after the gas source disconnection prompt is given, if the operator disconnects the gas source connected to one of the two insufflators 1100, the detection component corresponding to the insufflator 1100 that has its gas source disconnected will no longer send the gas source connection signal to the control system 1200, while the detection component corresponding to the insufflator 1100 that has not had its gas source disconnected can still send the gas source connection signal to the control system 1200, and thus the control system 1200 can determine the insufflator 1100 that has not had its gas source disconnected as the second insufflator 1104, and determine the insufflator 1100 that has its gas source disconnected as the first insufflator 1102.

[0078] In some embodiments, the control system 1200 includes a control terminal, which is configured outside the insufflator 1100 , and the control terminal is used to determine the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 .

[0079] In this way, the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 can be determined through a control terminal outside the insufflator 1100, which is beneficial to improving control accuracy.

[0080] Exemplarily, the control terminal includes but is not limited to a mobile phone, a portable computer, a computer, etc. The control terminal can communicate with the two pneumoperitoneum machines 1100 .

[0081] In some embodiments, the insufflator system 1000 further includes an interactive component. When determining the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, the control system 1200 is specifically configured to: receive a configuration instruction of the insufflator 1100 through the interactive component; and determine the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100 according to the configuration instruction of the insufflator 1100.

[0082] In this way, the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 can be accurately determined based on the configuration instructions of the insufflator 1100, thereby improving the degree of freedom of operation and being conducive to meeting the operation requirements of different operators.

[0083] Optionally, the interactive component may include one or more of a setting button, a touch display screen, and a wireless communication module configured on the pneumoperitoneum machine 1100.

[0084] In one example, the interactive component includes a setting button configured on the insufflator 1100, and the setting button is used to set the insufflator 1100 to be the first insufflator 1102 or the second insufflator 1104. The operator can manually set the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 through the setting button. After the setting, the control system 1200 can automatically receive the configuration instructions of the insufflator 1100, and then determine the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 according to the configuration instructions of the insufflator 1100.

[0085] In another example, the interactive component includes a touch screen configured on the insufflator 1100, and the touch screen may include a setting control. The setting control is used to set the insufflator 1100 where the touch screen is located to be the first insufflator 1102 or the second insufflator 1104. The operator can manually set the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 through the setting control. After the setting, the control system 1200 can automatically receive the configuration instructions of the insufflator 1100, and then determine the first insufflator 1102 and the second insufflator 1104 of the two insufflator 1100 according to the configuration instructions of the insufflator 1100.

[0086] In another example, the control system 1200 includes a control terminal and a controller configured on the insufflator 1100, and the interactive component includes a wireless communication module configured on the insufflator 1100. The controller can communicate with the control terminal through the wireless communication module. The operator can set the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100 on the control terminal, and then the control terminal automatically generates configuration instructions for the insufflator 1100, and sends the configuration instructions for the insufflator 1100 to the controller through the wireless communication module, and then the controller can determine the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100 according to the configuration instructions of the insufflator 1100.

[0087] In some embodiments, the air inlets of the two insufflators 1100 are respectively provided with air inlet valves, and the two insufflators 1100 can be connected to the air source through the air inlet valves. After determining the first insufflator 1102 and the second insufflator 1104 of the two insufflators 1100, the control system 1200 is further used to: control the air inlet valve of the first insufflator 1102 to close, and control the air inlet valve of the second insufflator 1104 to open.

[0088] In this way, it is convenient to control the first pneumoperitoneum machine 1102 to detect the target abdominal cavity pressure and to control the second pneumoperitoneum machine 1104 to provide gas to the target abdominal cavity.

[0089] Please continue to combine Figure 1In some embodiments, the pneumoperitoneum system 1000 further includes a first pipeline 1500. One end of the first pipeline 1500 is connected to the first pneumoperitoneum machine 1102, and the other end of the first pipeline 1500 can be connected to the target abdominal cavity.

[0090] Exemplarily, one end of the first pipeline 1500 can be connected to the first pneumoperitoneum machine 1102 through the first filter 1700, and the other end of the first pipeline 1500 can be connected to the target abdominal cavity through the first puncture device.

[0091] Please continue to combine Figure 1 In some embodiments, the pneumoperitoneum system 1000 further includes a second pipeline 1600. One end of the second pipeline 1600 is connected to the second pneumoperitoneum machine 1104, and the other end of the second pipeline 1600 can be connected to the target abdominal cavity.

[0092] In this way, the second pipeline 1600 is used to connect the second pneumoperitoneum machine 1104 and the target abdominal cavity, which is conducive to the second pneumoperitoneum machine 1104 to better provide gas to the target abdominal cavity.

[0093] Exemplarily, one end of the second pipeline 1600 can be connected to the second pneumoperitoneum machine 1104 through the second filter 1800, and the other end of the second pipeline 1600 can be connected to the target abdominal cavity through the second puncture device.

[0094] In some embodiments, the first pneumoperitoneum machine 1102 is provided with a first pressure sensor, and the control system 1200 is used to control the first pneumoperitoneum machine 1102 to obtain the target abdominal cavity pressure through the first pressure sensor.

[0095] It can be understood that since the first pipeline 1500 is only connected to the target abdominal cavity and the first pneumoperitoneum machine 1102, but not directly connected to the second pneumoperitoneum machine 1104, when the second pneumoperitoneum machine 1104 provides gas to the target abdominal cavity, the airflow in the first pipeline 1500 is relatively stable and basically does not affect the pressure detection, so that the first pressure sensor can more accurately detect the target abdominal cavity pressure.

[0096] In some embodiments, the second pneumoperitoneum machine 1104 is provided with a second pressure sensor, and the pneumoperitoneum machine system 1000 further includes two state acquisition circuits, which can respectively acquire the working states of the two pneumoperitoneum machines 1100 and send the acquired working states to the control system 1200, wherein the working states include abnormal states or normal states. The control system 1200 is further used for: when one of the two pneumoperitoneum machines 1100 is in an abnormal state and the other of the two pneumoperitoneum machines 1100 is in a normal state, controlling the pneumoperitoneum machine 1100 in a normal state among the two pneumoperitoneum machines 1100 to obtain the target abdominal cavity pressure and provide gas to the target abdominal cavity.

[0097] In this way, when an abnormality occurs in one of the two insufflators 1100 , the insufflator system 1000 can still be ensured to continue operating, facilitating subsequent surgical operations.

[0098] It can be understood that since the first insufflator 1102 and the second insufflator 1104 have the same structure and the first pipeline 1500 and the second pipeline 1600 have the same structure, the first insufflator 1102 and the second insufflator 1104 can achieve the same function, the first insufflator 1102 can obtain the target abdominal cavity pressure and provide gas to the target abdominal cavity, and the second insufflator 1104 can also obtain the target abdominal cavity pressure and provide gas to the target abdominal cavity. Therefore, when one of the first insufflator 1102 and the second insufflator 1104 is in an abnormal state, the other insufflator 1100 of the first insufflator 1102 and the second insufflator 1104 can obtain the target abdominal cavity pressure and provide gas to the target abdominal cavity.

[0099] Specifically, when controlling the pneumoperitoneum machine 1100 in a normal state among the two pneumoperitoneum machines 1100 to obtain the target abdominal cavity pressure and supply gas to the target abdominal cavity, the pneumoperitoneum machine 1100 in a normal state can adopt pulsed gas supply, that is, periodically stop supplying gas to the target abdominal cavity, and then measure the target abdominal cavity pressure during the period of stopping supplying gas to the target abdominal cavity.

[0100] For example, when a pipeline is blocked or the pneumoperitoneum machine 1100 fails, the state acquisition circuit may detect that the pneumoperitoneum machine 1100 is in an abnormal state.

[0101] For example, for the pneumoperitoneum machine 1100 in an abnormal state, it can be controlled to stop providing gas to the target abdominal cavity and to stop detecting the target abdominal cavity pressure.

[0102] In certain embodiments, the control system 1200 is also used to: issue a fault alarm when it is detected that the pneumoperitoneum machine 1100 is in an abnormal state, thereby facilitating the operator to promptly discover and resolve the abnormal state of the pneumoperitoneum machine 1100 and ensure the safety of the surgical operation.

[0103] In some embodiments, the second pneumoperitoneum machine 1104 is provided with a second pressure sensor, and the pneumoperitoneum machine system 1000 further includes a state acquisition circuit, which can collect the working states of the two pneumoperitoneum machines 1100 in turn, and send the collected working states to the control system 1200, and the working states include abnormal states or normal states. The control system 1200 is also used for: when one of the two pneumoperitoneum machines 1100 is in an abnormal state and the other of the two pneumoperitoneum machines 1100 is in a normal state, controlling the pneumoperitoneum machine 1100 in a normal state among the two pneumoperitoneum machines 1100 to obtain the target abdominal cavity pressure and provide gas to the target abdominal cavity.

[0104] In this way, when an abnormality occurs in one of the two insufflators 1100 , the insufflator system 1000 can still be ensured to continue operating, facilitating subsequent surgical operations.

[0105] In some embodiments, the second insufflator 1104 includes a flow regulator, which is connected to the control system 1200. The control system 1200 is also used to adjust the gas supply flow through the flow regulator.

[0106] This makes the process of providing gas to the target abdominal cavity more precise and controllable.

[0107] Please combine Figure 2 In one example, the pneumoperitoneum machine 1100 may further include a third pressure sensor 1106, a first pressure reducing valve 1108, a second pressure reducing valve 1110, a first safety valve 1112, a proportional valve 1114, a flow meter 1116, a switch valve 1118, a second safety valve 1120, an exhaust valve 1122, a fourth pressure sensor 1124, and a fifth pressure sensor 1126, wherein the proportional valve 1114, the flow meter 1116, and the switch valve 1118 may be part of a flow regulator. The fourth pressure sensor 1124 and the fifth pressure sensor 1126 may be understood as sensors for measuring target abdominal cavity pressure.

[0108] In one example, two pneumoperitoneum machines 1100 in the pneumoperitoneum machine system 1000 have the same structure, and can include a power interface 1101, a power circuit 1103, a controller 1105, a display screen 1107, a communication interface 1109, an air inlet 1111, a gas flow detection circuit 1113, an abdominal pressure control circuit 1115, an abdominal pressure detection circuit 1117, a gas temperature control circuit 1119, a pipeline heating interface 1121 and an air outlet 1123, as shown in FIG. Figure 3 As shown. The gas flow detection circuit 1113 can detect the gas supply flow when providing gas to the target abdominal cavity. The abdominal cavity pressure control circuit 1115 can control the target abdominal cavity pressure. The abdominal cavity pressure detection circuit 1117 can obtain the target abdominal cavity pressure. The gas temperature control circuit 1119 can control the gas temperature when providing gas to the target abdominal cavity. The gas flow detection circuit 1113, the abdominal cavity pressure control circuit 1115, the abdominal cavity pressure detection circuit 1117 and the gas temperature control circuit 1119 can be understood as the main gas circuit.

[0109] Further, in a scenario where the first pneumoperitoneum machine 1102 obtains the target abdominal cavity pressure and the second pneumoperitoneum machine 1104 provides gas to the target abdominal cavity, the components running in the first pneumoperitoneum machine 1102 and the second pneumoperitoneum machine 1104 are as follows: Figure 4 As shown, in Figure 4In the example, the first pipeline and the second pipeline are not shown, and the shaded components indicate that they are not operating in the current scenario.

[0110] Based on the same inventive concept, an insufflator system control method corresponding to the insufflator system is also provided in the embodiment of the present disclosure. Since the principle of solving the problem by the insufflator system control method in the embodiment of the present disclosure is similar to that of the above-mentioned insufflator system in the embodiment of the present disclosure, the implementation of the insufflator system control method can refer to the implementation of the insufflator system, and the repeated parts will not be repeated.

[0111] Figure 5 FIG. 1 is a flow chart of a method for controlling an insufflator system according to some embodiments of the present disclosure. The method for controlling an insufflator system can be used to control an insufflator system according to any of the aforementioned embodiments. Figure 5 The pneumoperitoneum machine system control method M100 provided in the present disclosure may include step S110, step S120 and step S130.

[0112] S110: Determine a first insufflator and a second insufflator of two insufflators.

[0113] S120: Control the first pneumoperitoneum machine to obtain the target abdominal cavity pressure.

[0114] S130: Controlling the second pneumoperitoneum machine to provide gas to the target abdominal cavity according to the target abdominal cavity pressure.

[0115] The insufflator system control method of the disclosed embodiment first determines the first insufflator and the second insufflator among the two insufflators, and then obtains the target abdominal cavity pressure through the first insufflator, and supplies gas to the target abdominal cavity according to the target abdominal cavity pressure through the second insufflator. That is, obtaining the target abdominal cavity pressure and supplying gas to the target abdominal cavity are completed by different insufflators, and gas can be continuously supplied to the target abdominal cavity while obtaining the accurate target abdominal cavity pressure. There is no need to stop supplying gas to the target abdominal cavity in order to obtain the accurate target abdominal cavity pressure, which is beneficial to improving the efficiency of gas replenishment and air leakage, stably maintaining the pressure in the target abdominal cavity, and facilitating surgical operations.

[0116] In some embodiments, step S110 may include: detecting a gas source connection signal; and when it is detected that one of the insufflators sends a gas source connection signal and the other insufflator does not send a gas source connection signal, using the insufflator that sends the gas source connection signal as the second insufflator, and using the insufflator that does not send the gas source connection signal as the first insufflator.

[0117] In some embodiments, step S110 may include: detecting a gas source connection signal; and when detecting that one of the insufflators sends a gas source connection signal, using the insufflator that sends the gas source connection signal as the second insufflator, and directly using the other of the two insufflators as the first insufflator.

[0118] In some embodiments, after detecting the gas source connection signal, it also includes: when it is detected that both insmothermal machines have not sent the gas source connection signal, issuing a gas source connection prompt, the gas source connection prompt is used to indicate that any one of the two insmothermal machines should be connected to the gas source; and when it is detected that both insmothermal machines have sent the gas source connection signal, issuing a gas source disconnection prompt, the gas source disconnection prompt is used to indicate that any one of the two insmothermal machines should be disconnected from the gas source.

[0119] In some embodiments, step S110 may include: receiving an insufflator configuration instruction; and determining a first insufflator and a second insufflator of two insufflators according to the insufflator configuration instruction.

[0120] In some embodiments, after step S130, it also includes: detecting the working status of the two pneumoperitoneum machines, the working status including an abnormal state or a normal state; and when one of the two pneumoperitoneum machines is in an abnormal state and the other of the two pneumoperitoneum machines is in a normal state, controlling the pneumoperitoneum machine in the normal state among the two pneumoperitoneum machines to perform target abdominal cavity pressure detection and provide gas to the target abdominal cavity.

[0121] In some embodiments, both insufflators include a pressure detection module and an air supply module. After determining the first insufflator and the second insufflator among the two insufflators, it also includes: controlling the pressure detection module of the first insufflator to work while the air supply module does not work, and controlling the air supply module of the second insufflator to work while the pressure detection module does not work.

[0122] In some embodiments, both insmothermal machines include a pressure detection module, an air supply module and a controller. When the insmothermal machine works as an independent insmothermal machine, the controller can control the pressure detection module of the insmothermal machine to obtain the target abdominal cavity pressure, and control the air supply module of the insmothermal machine to provide gas to the target abdominal cavity according to the target abdominal cavity pressure.

[0123] Exemplarily, the insufflator is a insufflator in which the controller is located.

[0124] It should be pointed out that the two pneumoperitoneum machines disclosed in the present invention can form a pneumoperitoneum machine system, in which the two machines cooperate with each other to work; the two pneumoperitoneum machines disclosed in the present invention may not form a pneumoperitoneum machine system, but work separately as independent pneumoperitoneum machines. The two pneumoperitoneum machines can be configured to work in cooperation with each other or separately according to the precision requirements of the air pressure control in the operation, thereby increasing the application scenarios and utilization rate of the pneumoperitoneum machines. In addition, the pneumoperitoneum machine system disclosed in the present invention can also be constructed using the existing pneumoperitoneum machines in the hospital, thereby improving the precision of the pneumoperitoneum machine without increasing the cost.

[0125] In addition, considering that continuously providing gas to the target abdominal cavity may cause compressive damage to the organs in the target abdominal cavity, the present disclosure also proposes a communication method and a communication system.

[0126] Combined with the following Figures 6 to 9 The communication method, communication system, etc. disclosed in the present invention are described in detail.

[0127] Figure 6 is a flow chart of the communication method of some embodiments of the present disclosure. The communication method provided by the present disclosure is used for the second pneumoperitoneum machine. Figure 6 , the communication method M200 provided in the present disclosure may include step S210, step S220 and step S230.

[0128] S210: Send a connection detection request to the first insufflator, where the connection detection request can instruct the first insufflator to return a connection detection response.

[0129] S220: In response to receiving a connection detection response sent by the first insufflator, an abdominal pressure detection instruction is sent to the first insufflator, and the abdominal pressure detection instruction can instruct the first insufflator to detect a target abdominal pressure and return abdominal pressure detection data according to the target abdominal pressure.

[0130] S230: In response to receiving the abdominal cavity pressure detection data sent by the first pneumoperitoneum machine, providing gas to the target abdominal cavity according to the abdominal cavity pressure detection data.

[0131] The communication method of the embodiment of the present disclosure, upon receiving a connection detection response sent by the first pneumoperitoneum machine, sends an abdominal pressure detection instruction to the first pneumoperitoneum machine to obtain abdominal pressure detection data, and provides gas to the target abdominal cavity according to the abdominal pressure detection data, thereby effectively establishing a laparoscopic surgical operating space and providing an appropriate amount of gas to the target abdominal cavity according to the target abdominal pressure, thereby avoiding compressive damage to the target abdominal organs due to supplying too much gas, which is conducive to safe and smooth laparoscopic surgery.

[0132] Optionally, the communication method of the embodiment of the present disclosure may be used in the pneumoperitoneum machine system of the aforementioned embodiment.

[0133] Optionally, the first insufflator and the second insufflator are connected via a communication line, thereby facilitating high-speed transmission of abdominal pressure detection data.

[0134] Exemplarily, the second insufflator may periodically send a connection detection request to the first insufflator after the device is powered on, and may further periodically obtain abdominal pressure detection data, which is beneficial for dynamically adjusting the gas supply flow when providing gas to the target abdominal cavity according to the abdominal pressure detection data.

[0135] Exemplarily, the abdominal cavity pressure detection data can represent the target abdominal cavity pressure, and then after receiving the abdominal cavity pressure detection data sent by the first insufflator, the second insufflator can reasonably provide gas to the target abdominal cavity according to the abdominal cavity pressure detection data.

[0136] In one example, the communication architecture diagram of the first pneumoperitoneum machine and the second pneumoperitoneum machine is as follows: Figure 7 As shown, the first pneumoperitoneum machine 1102 may include a first controller 1202, a first level conversion chip 1127 and a first serial communication interface 1302, and the second pneumoperitoneum machine 1104 may include a second controller 1204, a second level conversion chip 1128 and a second serial communication interface 1304, and the first serial communication interface 1302 and the second serial communication interface 1304 are connected through a communication line. The first serial communication interface 1302 and the second serial communication interface 1304 may be DB9 interfaces. The first serial communication interface 1302 and the second serial communication interface 1304 may communicate based on the RS-232 communication standard, the communication baud rate may be 115200, the data bit may be 8 bits, and the stop bit may be 1 bit. The first controller 1202 and the first level conversion chip 1127 may perform data transmission based on the TTL (Transistor-Transistor Logic, transistor-transistor logic) level standard, and the second controller 1204 and the second level conversion chip 1128 may also perform data transmission based on the TTL level standard.

[0137] Furthermore, each frame of data transmitted between the first pneumoperitoneum machine and the second pneumoperitoneum machine may include a frame header part (13 bytes), a parameter part (113 bytes) and a check part (2 bytes), and the maximum length of each frame of data may be 128 bytes, as shown in Table 1.

[0138] Table 1 Frame format description

[0139] Frame header Parameters section Verification part

[0140] The format of the frame header is shown in Table 2. The frame type may include: 0x02, indicating that the second insufflator actively sends to the first insufflator; 0x03, indicating that the second insufflator sends to the first insufflator; 0x04, indicating that the first insufflator sends to the second insufflator; 0x05, indicating that an error report is sent.

[0141] Table 2 Format of the frame header

[0142]

[0143] The parameter part includes the data to be transmitted, including query, setting, action, test and other related instructions or data, such as target abdominal pressure. Unsigned characters can be used in the parameter part.

[0144] The verification part includes the verification results. The format of the verification part is shown in Table 3.

[0145] Table 3 Format of the verification part

[0146] CRC check value (high byte) CRC check value (low byte)

[0147] In one example, a first insufflator and a second insufflator may form a dual-machine communication system, and the double-machine communication system adopts a bus-type master-slave structure, wherein the second insufflator serves as a host and can perform communication management task processing; the first insufflator serves as a slave and can respond to the scheduling and control of the host, for example, sending abdominal pressure detection data.

[0148] In one example, the communication protocol of the second insufflator may include a basic protocol and a functional protocol. The basic protocol may include one or more of querying device information, heartbeat detection, setting the working mode according to the gas source, and querying the working status of the master and slave machines. The functional protocol may include one or more of intermittent valve cutting (pulse gas injection), continuous gas injection, fault alarm, and safety guard mechanism. The communication protocol of the first insufflator is the same as that of the second insufflator, which will not be repeated here.

[0149] In some embodiments, the abdominal pressure detection data includes a target abdominal pressure and a first verification result, wherein the first verification result is obtained by the first pneumoperitoneum machine performing data verification on the target abdominal pressure based on a target verification algorithm. Step S230 includes: performing data verification on the target abdominal pressure based on the target verification algorithm to obtain a second verification result; and providing gas to the target abdominal cavity according to the first verification result and the second verification result.

[0150] In this way, the abdominal pressure detection data sent by the first insufflator includes the target abdominal pressure and the first verification result. After receiving the abdominal pressure detection data sent by the first insufflator, the second insufflator first performs data verification on the target abdominal pressure in the abdominal pressure detection data based on the target verification algorithm to obtain the second verification result, and then provides gas to the target abdominal cavity based on the first verification result and the second verification result, thereby facilitating timely detection and processing of target abdominal pressure that is transmitted incorrectly during the communication process, and effectively improving the accuracy of the target abdominal pressure used by the second insufflator.

[0151] It is understandable that during laparoscopic surgery, it is necessary to establish a surgical space in the abdominal cavity, which requires the infusion of gas (such as CO2 gas) into the abdominal cavity to raise the anterior abdominal wall in order to have a good field of view and facilitate the operation of instruments. The pneumoperitoneum machine is a device for establishing and maintaining pneumoperitoneum during laparoscopic surgery. Due to factors such as the environment and transmission distance, the data transmitted during the communication process may be erroneous. If the target abdominal pressure is incorrect during the communication process, causing the pneumoperitoneum machine to use the wrong target abdominal pressure, it will affect the surgical operation and even endanger the life of the patient on the operating table. Therefore, it is crucial to ensure the accuracy of the target abdominal pressure used by the pneumoperitoneum machine.

[0152] Exemplarily, the target check algorithm may include a cyclic redundancy check algorithm, such as CRC ITU-T (x^16+x^12+x^5+x^1).

[0153] Exemplarily, the second pneumoperitoneum machine may use a cyclic redundancy check algorithm to perform data verification on the target abdominal cavity pressure, thereby obtaining a second verification result.

[0154] Exemplarily, the second pneumoperitoneum machine may compare the first verification result with the second verification result to obtain a comparison result, and then provide gas to the target abdominal cavity according to the comparison result.

[0155] In some embodiments, providing gas to the target abdominal cavity based on the first verification result and the second verification result includes: in response to the first verification result being the same as the second verification result, providing gas to the target abdominal cavity based on the target abdominal cavity pressure; in response to the first verification result being different from the second verification result, sending a first retransmission instruction to the first pneumoperitoneum machine, and re-receiving the abdominal pressure detection data, the first retransmission instruction being able to instruct the first pneumoperitoneum machine to resend the abdominal pressure detection data.

[0156] It can be understood that when the first test result is the same as the second test result, it can be considered that the target abdominal pressure received by the second pneumoperitoneum machine is the same as the target abdominal pressure sent by the first pneumoperitoneum machine, that is, the accuracy of the target abdominal pressure is not affected during the data transmission process. Therefore, the second pneumoperitoneum machine can directly provide gas to the target abdominal cavity according to the target abdominal pressure in the received abdominal pressure detection data, thereby ensuring the safety of the operation.

[0157] It can be understood that when the first test result is different from the second test result, it can be considered that there is a difference between the target abdominal pressure received by the second insufflator and the target abdominal pressure sent by the first insufflator, that is, the accuracy of the target abdominal pressure is affected during the data transmission process. At this time, re-receiving the abdominal pressure detection data can avoid using the previously received target abdominal pressure with a difference for subsequent control, thereby improving the accuracy of the target abdominal pressure used by the second insufflator, and facilitating the safe conduct of surgical operations.

[0158] Exemplarily, the first retransmission instruction may be preset by relevant personnel, or may be automatically generated in real time by the second pneumoperitoneum machine, which is not limited here.

[0159] Exemplarily, when the first pneumoperitoneum machine resends the abdominal cavity pressure detection data, it can directly resend the abdominal cavity pressure detection data sent last time without redetecting the target abdominal cavity pressure and generating new abdominal cavity pressure detection data before sending.

[0160] In some embodiments, before sending the first retransmission instruction to the first pneumoperitoneum machine, it also includes: determining the error details and the corresponding error code based on the difference between the first verification result and the second verification result; writing the error details and the error code into a preset retransmission instruction template to obtain the first retransmission instruction.

[0161] In this way, after receiving the first retransmission instruction, the first pneumoperitoneum machine can determine the error details and error code from the first retransmission instruction.

[0162] Exemplarily, when the first verification result is different from the second verification result, the difference between the first verification result and the second verification result can be determined, and the difference can be used as the error details, and the error code corresponding to the error details can be determined according to the target mapping relationship. The target mapping relationship may include multiple preset error details and their corresponding preset error codes.

[0163] Exemplarily, the preset retransmission instruction template may be a retransmission instruction template in a preset response mechanism between both parties in the communication process.

[0164] In some implementations, an error report may also be stored, the content of the error report including error details and an error code.

[0165] In some embodiments, after obtaining the second verification result, it also includes: in response to the first verification result being the same as the second verification result, determining a target confirmation signal; sending a target confirmation signal to the first pneumoperitoneum machine, the target confirmation signal can indicate that the first pneumoperitoneum machine successfully receives the abdominal pressure detection data.

[0166] This helps the first pneumoperitoneum machine to understand the reception status of the abdominal pressure detection data, which is beneficial for data tracking.

[0167] In one example, determining the target confirmation signal includes: using the abdominal pressure detection data as the target confirmation signal. In this way, after receiving the target confirmation signal, the first insufflator can quickly know that the second insufflator has successfully received the abdominal pressure detection data sent previously.

[0168] In another example, determining the target confirmation signal includes: using a pre-configured confirmation signal as the target confirmation signal. In this way, the first insufflator can be informed that the second insufflator has successfully received the abdominal pressure detection data sent previously based on the confirmation signal pre-agreed by both parties.

[0169] In some embodiments, the communication method further includes: in response to detecting that the reception time length of the target data is greater than the reception time length threshold, sending a second retransmission instruction to the first pneumoperitoneum machine, wherein the second retransmission instruction can instruct the first pneumoperitoneum machine to resend the target data.

[0170] In this way, a timeout mechanism is added during the communication process to prevent the second pneumoperitoneum machine from failing to respond.

[0171] Exemplarily, the target data may be understood as any data that the second pneumoperitoneum machine needs to receive. The target data may include abdominal pressure detection data. The receiving time threshold may be preset by relevant personnel and is not limited here. The second retransmission instruction may be preset by relevant personnel or may be automatically generated in real time by the second pneumoperitoneum machine and is not limited here.

[0172] Exemplarily, since the transmission duration of each byte in the target data is fixed, and the total transmission duration of each frame of target data is also fixed, during the transmission of one frame of target data, if the second insufflator detects that any byte in the target data is lost or the receiving duration of the target data is greater than the receiving duration threshold (i.e., the fixed total transmission duration), a second retransmission instruction is sent to the first insufflator.

[0173] Exemplarily, when the first pneumoperitoneum machine resends the target data, it may directly resend the target data sent last time without re-detecting, generating or determining new target data before sending.

[0174] In some embodiments, after sending a connection detection request to the first insufflator, it also includes: in response to receiving a connection detection response, sending a connection detection request to the first insufflator based on a first interval duration; in response to not receiving a connection detection response, sending a connection detection request to the first insufflator based on a second interval duration, the first interval duration being greater than the second interval duration.

[0175] In this way, a heartbeat detection mechanism is added during the communication process, and based on the connection detection response of the first insufflator, it is regularly determined whether the communication connection between the first insufflator and the second insufflator is normal, which is conducive to ensuring the smooth operation of the insufflator system. It is conducive to long-term monitoring of the target abdominal cavity pressure, improving the accuracy of the target abdominal cavity pressure used by the second insufflator, and facilitating the safe operation of the surgical operation.

[0176] Exemplarily, after the first insufflator establishes a communication connection with the second insufflator, the second insufflator can automatically trigger a connection detection request to the first insufflator by sending a heartbeat packet. If a connection detection response is received from the first insufflator, a connection detection request is sent to the first insufflator once every first interval. If no connection detection response is received from the first insufflator, a connection detection request is sent to the first insufflator once every second interval.

[0177] Exemplarily, the first interval duration and the second interval duration may be preset by relevant personnel, which is not limited here.

[0178] In one example, the first interval duration is 2 seconds, and the second interval duration is much shorter than 2 seconds.

[0179] In some embodiments, when a connection detection response is not received, a communication connection prompt can be provided, which can prompt the operator to promptly check the communication connection between the first insufflator and the second insufflator. In this way, it is convenient to restore communication in time when the communication connection between the first insufflator and the second insufflator is disconnected, thereby ensuring the normal operation of the insufflator system and facilitating the smooth progress of the surgical operation.

[0180] Based on the same inventive concept, the presently disclosed embodiment also provides a communication method for the first insufflator corresponding to the communication method for the second insufflator. Since the principle of solving the problem by the communication method for the first insufflator in the presently disclosed embodiment is similar to that of the communication method for the second insufflator in the presently disclosed embodiment, the implementation of the communication method for the first insufflator can refer to the implementation of the communication method for the second insufflator, and the repeated parts will not be repeated.

[0181] Figure 8 is another flow chart of the communication method of some embodiments of the present disclosure. The communication method provided by the present disclosure is used for a first pneumoperitoneum machine. Figure 8 , the communication method M300 provided in the present disclosure may include step S310, step S320 and step S330.

[0182] S310: In response to receiving the connection detection request sent by the second insufflator, sending a connection detection response to the second insufflator, where the connection detection response can instruct the second insufflator to send an abdominal pressure detection instruction.

[0183] S320: In response to receiving the abdominal cavity pressure detection instruction sent by the second pneumoperitoneum machine, detecting the target abdominal cavity pressure.

[0184] S330: Sending abdominal cavity pressure detection data to the second insufflator according to the target abdominal cavity pressure.

[0185] In some embodiments, abdominal pressure detection data is sent to a second pneumoperitoneum machine based on the target abdominal pressure, including: performing data verification on the target abdominal pressure based on a target verification algorithm to obtain a first verification result; sending abdominal pressure detection data to the second pneumoperitoneum machine, the abdominal pressure detection data including the target abdominal pressure and the first verification result, the abdominal pressure detection data can trigger the second pneumoperitoneum machine to perform data verification on the target abdominal pressure based on the target verification algorithm to obtain a second verification result, and provide gas to the target abdominal cavity based on the first verification result and the second verification result.

[0186] In some embodiments, it also includes: in response to receiving a first retransmission instruction sent by the second pneumoperitoneum machine, re-sending the abdominal pressure detection data to the second pneumoperitoneum machine, the first retransmission instruction being determined by the second pneumoperitoneum machine when the first verification result is different from the second verification result.

[0187] In some embodiments, the first retransmission instruction is obtained by the second pneumoperitoneum machine by writing error details and error code into a preset retransmission instruction template when the first verification result is different from the second verification result, and the error details and error code are obtained by the second pneumoperitoneum machine based on the difference between the first verification result and the second verification result.

[0188] In some embodiments, the communication method further includes: in response to receiving a second retransmission instruction sent by the second pneumoperitoneum machine, resending the target data to the second pneumoperitoneum machine, the second retransmission instruction being determined by the second pneumoperitoneum machine when it detects that the reception time of the target data is greater than a reception time threshold.

[0189] Based on the same inventive concept, a communication system corresponding to the communication method for a second pneumoperitoneum machine is also provided in the embodiment of the present disclosure. Since the principle of solving the problem by the communication system in the embodiment of the present disclosure is similar to the communication method for the second pneumoperitoneum machine in the embodiment of the present disclosure, the implementation of the communication system can refer to the implementation of the communication method for the second pneumoperitoneum machine, and the repeated parts will not be repeated.

[0191] Among them, the first insufflator 1102 is used to send a connection detection response to the second insufflator upon receiving a connection detection request sent by the second insufflator, and is used to detect the target abdominal pressure upon receiving an abdominal pressure detection instruction sent by the second insufflator, and is used to send abdominal pressure detection data to the second insufflator according to the target abdominal pressure.

[0192] The second insufflator 1104 is used to send a connection detection request to the first insufflator, and to send an abdominal pressure detection instruction to the first insufflator when receiving a connection detection response sent by the first insufflator, and to provide gas to the target abdominal cavity according to the abdominal pressure detection data when receiving the abdominal pressure detection data sent by the first insufflator.
