DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] In order to describe the object, technical matters and effects of the present invention in more detail, the technical matters of the embodiments of the present invention will be described in more detail and fully below with reference to the drawings of the embodiments of the present invention. The following embodiments are only a part of the embodiments of the present invention and do not represent all the embodiments. When referring to the embodiments of the present invention, a person skilled in the art can come up with other embodiments without creative research, and of course, these are included in the present invention.

[0012] Referring to Fig. 1, Fig. 1 is a diagram showing an application example of a method for controlling RF operation data according to an embodiment of the present invention. The method for controlling RF operation data can be implemented by a radio frequency host 10 or a syringe pump 20 in Fig. 1. The method for controlling RF operation data can also be implemented by computer equipment other than the RF host 10 or the syringe pump 20. The computer equipment can be, for example, a server, a desktop computer, a notebook computer, a laptop computer, a tablet personal computer, a personal computer, a smartphone, etc.

[0013] As shown in Fig. 1, the RF operating system includes an RF host 10, a syringe pump 20 with multiple injection passages, multiple temperature detection devices 30, an RF operating catheter 40, an indifferent electrode 50, and a resistance detection device 60. The multiple temperature detection devices 30 and the resistance detection device 60 are attached to the top of the RF operating catheter 40 or to the top of the extension tube 232 of the syringe pump 20. The multiple temperature detection devices 30 are used to detect the temperature of multiple parts of the operating site. The resistance detection device 60 is used to detect the resistance of the operating site of the RF object.

[0014] Hereinafter, the RF host 10 will be described as an example of the RF operation data control method according to the embodiment of the present invention. Specifically, the top of the RF operation catheter 40 that forms and outputs RF energy and the top of the extension tube 232 of the syringe pump 20 are inserted into the body of the RF operation target. That is, the top of the RF operation catheter 40 that forms and outputs RF energy and the top of the extension tube 232 of the syringe pump 20 are inserted to a predetermined operation site. Next, the neutral electrode 50 is abutted against the surface of the RF operation target. A current circuit is formed by RF current flowing through the RF operation catheter 40, the RF operation target, and the neutral electrode 50. When the RF operation is triggered, the RF host 10 controls the discharge of the RF operation catheter 40 to output RF energy to the operation site, and RF operation can be performed on the operation site.

[0015] At this time, the RF host 10 can open at least one injection passage of the syringe pump 20, thereby controlling the syringe pump 20 to inject liquid at a preset initial flow rate (preset initial flow rate, the same below) and inject liquid into the operation site. When the control mode of the RF operation data is a dual control mode, the temperatures of multiple positions of the operation site are obtained continuously by multiple temperature detection devices 30, and the syringe pump 20 can control the opening and closing of some or all of the injection passages according to the real-time changes of the temperature values ​​of each position, or the syringe pump 20 can control the flow rates of some or all of the injection passages.

[0016] When the flow rate of the syringe pump 20 reaches a preset temperature control limit value but the temperature values ​​of the multiple sites are still outside the temperature protection range, the RF output power is controlled so that the temperature values ​​of the multiple sites are within the temperature protection range. At the same time, the resistance values ​​of the multiple sites are detected, and when the resistance values ​​of the multiple sites are outside the preset resistance protection range, the syringe pump 20 controls the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites are within the resistance protection range.

[0017] The RF manipulation target can be any object that needs to be RF manipulated. For example, when the RF host 10 is a radio frequency ablation instrument, the RF manipulation target can be an animal body that needs to ablate mutant tissue therein.

[0018] Referring to Figures 2 and 3, Figure 2 is a diagram showing the internal structure of a syringe pump according to an embodiment of the present invention, and Figure 3 is a diagram showing the internal structure of the injection structure 23 of Figure 2. For ease of explanation, Figures 2 and 3 only show parts according to the embodiment of the present invention, but in actual application, the syringe pump of the present invention may include more or less structures. As shown in Figures 2 and 3, the syringe pump 20 includes a control device 21, a plurality of temperature and resistance detection devices 22, and an injection structure 23 in which a plurality of injection passages are formed (hereinafter referred to as an injection structure with multiple passages).

[0019] The temperature and resistance detection device 22 includes a temperature detection circuit and a resistance detection circuit, and can respectively detect the temperature and resistance at various positions of the operation site by the temperature and resistance detection device 22. The temperature detection circuit and the resistance detection circuit can be integrated together or respectively integrated as two modules.

[0020] Each injection structure 23 includes a syringe 231, an extension tube 232, a push rod 233 and a driving device 234. Each injection structure 23 is formed with an injection passage.

[0021] One end of the extension tube 232 is connected to the syringe 231, and the other end is equipped with at least one temperature and resistance detection device 22 (for ease of explanation, only one temperature and resistance detection device 22 is shown in the drawings). One end of the push rod 233 abuts against the syringe 231, and the push rod 233 is connected to a drive device 234 (e.g., a stepping motor).

[0022] One end of each extension tube 232 to which the temperature and resistance detection device 22 is attached can be fixed around the top end 41 of the RF operation catheter 40 by a fixing structure. In the fixing structure, a plurality of through holes are formed in the side wall of the catheter, and a plurality of through holes are formed through the head and tail of the catheter. Each extension tube 232 and the top end 41 of the RF operation catheter 40 are inserted into the plurality of through holes. When each extension tube 232 is inserted into the through hole, the temperature and resistance detection device 22 attached to one end of each extension tube 232 is delivered from the through hole in the side wall of the catheter closest to the temperature and resistance detection device 22. A clawed structure is formed by the plurality of temperature and resistance detection devices 22, and the clawed structure can detect the temperature at various positions of the RF operation target or operation site.

[0023] Hereinafter, an injection structure having six injection passages will be described as an example. As shown in FIG. 8, the dotted circle indicates a plurality of through holes formed on the side wall of the catheter, and the six injection passages C1-C6 of the injection structure are formed around the RF manipulation catheter 40, and the six injection passages C1-C6 correspond to the six temperature detection devices T1-T6, respectively. The RF manipulation catheter 40 can be a monopolar RF manipulation catheter or a multipolar RF manipulation catheter, but the present invention is not limited thereto. When the RF manipulation catheter 40 is a multipolar RF manipulation catheter, at least one injection passage can be formed around each electrode of the multipolar RF manipulation catheter, or multiple electrodes can share one injection passage.

[0024] The control device 21 controls the opening and closing of the injection passage by controlling the drive device 234 that drives the push rod 233 to move in a predetermined direction. For example, when the push rod 233 pushes the tail of the syringe 231 in the forward direction, the injection passage is opened, and the liquid in the syringe 231 can flow to the RF operation target side through the injection passage. When the push rod 233 does not push the tail of the syringe 231 in the forward direction, the injection passage is closed, and the liquid in the syringe 231 cannot flow to the RF operation target side through the injection passage.

[0025] The control device 21 controls the moving speed of the push rod 233 via the drive device 234, and also controls the flow rate of the liquid in the injection passage.

[0026] A valve is attached on the extension tube 232 of each injection structure 23, and the control device 21 controls the opening and closing of the valve, thereby controlling the opening and closing of the injection passage.

[0027] The control device 21 is electrically connected to the temperature and resistance detection device 22 by data wire or wireless network, and is also electrically connected to the multi-passage injection structure 23. Thereby, each step in the RF operation data control method according to the embodiment of Fig. 4 to Fig. 7 can be implemented. Specifically, When an RF operation mission is triggered, control the injection operation at a preset initial flow rate by opening at least one injection passage; Determine a control mode of the RF operation data. If the control mode of the RF operation data is a dual control mode, obtain temperature values ​​of a plurality of portions of the RF operation object at any time; When the temperature values ​​of the plurality of parts exceed a temperature protection range, the syringe pump controls opening and closing of some or all of the injection passages according to real-time changes in the temperature values ​​of the plurality of parts, or the syringe pump controls the flow rate of some or all of the injection passages; When the flow rate of the syringe pump reaches a preset temperature control limit value but the temperature values ​​of the plurality of locations are still outside the temperature protection range, control RF output power so that the temperature values ​​of the plurality of locations are within the temperature protection range; The resistance values ​​of the multiple sites are detected, and when the resistance values ​​of the multiple sites exceed a preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites fall within the resistance protection range.

[0028] The specific process by which the control device 21 realizes a predetermined function can be referred to in the description of the embodiment of FIG. 4 to FIG. 7, so that it will not be described again here.

[0029] The syringe pump 20 may further include common devices such as a display panel, a power supply, etc., but the present invention is not limited thereto.

[0030] In the embodiment of the present invention, a multi-passage injection structure is used. When an RF operation task is triggered, the syringe pump is controlled to open at least one injection channel to perform an injection operation at a preset initial flow rate. The control mode of the RF operation data is determined, and when the control mode of the RF operation data is a dual control mode, the temperature of the multiple parts of the RF operation object is obtained from time to time, and the syringe pump controls the opening and closing of some or all of the injection channels, or the syringe pump controls the flow rate of some or all of the injection channels to adjust the temperature. In addition, when the flow rate of the syringe pump reaches a temperature control limit value, the RF output power is controlled to control the temperature. After the temperature control is completed, the resistance of the RF operation object is detected, and when the resistance value of a predetermined part exceeds a preset resistance protection range, the flow rate of the syringe pump is controlled to control the resistance value of the predetermined part. When an RF operation task is performed, the temperature and resistance of the RF operation object are respectively controlled to improve the effect of RF operation and ensure the safety of RF operation, and the multiple injection channels of the syringe pump can be dynamically controlled according to the real-time change of the temperature value of the multiple parts of the RF operation object. By appropriately adjusting the injection amount of the syringe pump according to the real-time change in temperature value of various parts of the RF operation target, it is possible to reduce delays in operation and operational errors due to manual judgment. In addition, it is possible to improve the speed, accuracy and appropriateness of injecting liquid when performing an RF operation task. As a result, it is possible to reduce damage caused by RF operation to the RF operation target and improve the safety of RF operation.

[0031] Referring to Fig. 4, Fig. 4 is a flow chart showing a method for controlling RF operation data according to an embodiment of the present invention. The method is used to control a syringe pump having a plurality of injection passages (hereinafter, referred to as a syringe pump with a plurality of injection passages), for example, the syringe pump 20 shown in Fig. 2 and Fig. 3. The method can be implemented by the syringe pump 20 of Fig. 1, or by the RF host 10 of Fig. 1, or by other computer equipment electrically connected to the syringe pump. Fig. 4 shows the method for controlling RF operation data, which includes the following steps:

[0032] In step S401, when an RF operation task is triggered, the syringe pump is controlled to open at least one injection passage, and the opened injection passage is used to perform an injection operation at a preset initial flow rate.

[0033] Specifically, the RF operation task can be triggered by a trigger command sent by another computer equipment when a preset trigger time is reached, or by detecting an operation of a user to trigger the RF operation task. The operation of triggering the RF operation task can be, for example, a user pressing a physical button or a virtual button to trigger the RF operation task.

[0034] Each time the syringe pump is started, it sets the injection parameters to pre-defined initial values, which may include, but are not limited to, the initial flow rate, total injection volume, injection time, etc.

[0035] When the RF operation task is triggered, the RF operation catheter performs RF operation on the RF operation target, thereby outputting RF energy to the RF operation target. In addition, the syringe pump opens at least one injection passage designated by the triggered injection control command, and opens a predetermined injection passage so as to perform the injection operation at a preset initial flow rate. This allows liquid to be injected into the RF operation target and the temperature of the RF operation target to be adjusted. This prevents the external tissue of the RF operation target from being burned due to high temperature, or prevents the desired operation effect from being not achieved due to low temperature.

[0036] The injection control command can be a command that is automatically triggered when the syringe pump detects a preset event, or a command that is sent to the syringe pump by an ablation controller or other computer equipment electrically connected to the syringe pump. The preset event can be a user pressing a physical or virtual button that triggers the injection control command, or an event that triggers an RF operation mission.

[0037] In step S402, a control mode of the RF operation data is determined. If the control mode of the RF operation data is a dual control mode, temperature values ​​of multiple positions of the RF operation object are obtained continuously.

[0038] Specifically, the temperatures of multiple locations of the RF operation target are continuously obtained by multiple temperature detection devices.

[0039] The data control mode can be set by the user, and includes a single control mode and a dual control mode, the single control mode includes a temperature single control mode and a resistance single control mode, and the dual control mode can be a resistance and temperature control mode.

[0040] Obtain setting information for a user to set a data control mode. If the user sets the data control mode, determine the control mode of the RF operation data according to the user's setting; if the user does not set the data control mode, set the control mode of the RF operation data to a dual control mode.

[0041] In the dual control mode, it is preferable to control the temperature first, and adjust the resistance after the temperature is in the normal range. In the temperature single control mode, only the temperature is adjusted, and in the resistance single control mode, only the resistance is adjusted. In the temperature single control mode, the RF operation data can also be controlled by the change of the temperature value, and in the resistance single control mode, the RF operation data can also be controlled by the change of the resistance value.

[0042] The method of controlling the RF operation data according to the change in the temperature value can be referred to steps S403 and S404 below, and will not be described again here.

[0043] Controlling the RF operation data by changing the resistance value is similar to controlling the RF operation data by changing the temperature value. When controlling the RF operation data by changing the resistance value, resistance is used instead of temperature, and the specific control process can be referred to the following steps S403 and S404, so it will not be described again here.

[0044] In step S403, when the temperature values ​​of the plurality of parts exceed the temperature protection range, the syringe pump controls the opening and closing of some or all of the injection passages according to real-time changes in the temperature values ​​of the plurality of parts, or the syringe pump controls the flow rate of some or all of the injection passages.

[0045] Specifically, the multiple temperature detection devices attached to the RF manipulation system are used to respectively detect the temperatures of multiple sites of the RF manipulation target. The multiple injection passages of the syringe pump are used to respectively inject liquid into multiple sites of the RF manipulation target. When a certain injection passage is opened, the liquid can flow into the certain site through the injection passage. One injection passage corresponds to at least one temperature detection device.

[0046] The temperature values ​​of the plurality of parts exceeding the preset temperature protection range means that the temperature value of at least one of the plurality of parts exceeds the maximum value of the temperature protection range or is smaller than the minimum value of the temperature protection range.

[0047] The temperatures of the plurality of parts of the operating part are continuously acquired, and the real-time changes of the temperature values ​​of the plurality of parts are analyzed, and when the real-time change trend and change amplitude of the plurality of temperature values ​​meet a preset condition, the syringe pump is controlled to open or close some or all of the injection passages, or the syringe pump is controlled to control the flow rate of some or all of the injection passages.

[0048] The preset condition can for example mean that the obtained temperature is greater than a preset maximum temperature and that the obtained temperature is less than a preset minimum temperature.

[0049] When the syringe pump controls the opening and closing of some or all of the injection passages, or when the syringe pump controls the flow rate of some or all of the injection passages, the syringe pump is controlled to perform at least one of the following operations:

[0050] The syringe pump is controlled so that it opens some of the injection passages, or closes some of the injection passages, or opens all of the injection passages, or closes all of the injection passages, or controls the flow rates of some of the injection passages, or controls the flow rates of all of the injection passages.

[0051] The flow rate of the injection passage means the flow rate of the liquid in the injection passage. By controlling the flow rate of the liquid in the injection passage, the injection amount of the injection passage can be controlled, and the temperature of the RF operation target can be adjusted.

[0052] When the injection passage is opened, the syringe pump can be automatically connected to the opened injection passage to perform the injection procedure.

[0053] In step S404, if the flow rate of the syringe pump reaches a preset temperature control limit value but the temperature values ​​of the multiple locations are still outside the temperature protection range, the RF output power is controlled so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0054] A temperature control limit value corresponding to the liquid flow rate of one syringe pump is preset. When it is detected that the flow rate of the syringe pump reaches the temperature control limit value but the temperature values ​​of the plurality of parts are still beyond the temperature protection range, the method of controlling the temperature by changing the flow rate is not adopted. In this case, the temperature is controlled by controlling the RF output power so that the temperature values ​​of the plurality of parts are within the temperature protection range. This can avoid injecting too much liquid, which may cause other physical damage to the RF operation target. The RF output power is the output power of the RF host.

[0055] In step S405, the resistance values ​​of the multiple sites are detected, and when the resistance values ​​of the multiple sites exceed a preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites fall within the resistance protection range.

[0056] When the temperature is controlled to a normal value, i.e., when the temperature value is within the temperature protection range, the resistance values ​​of the plurality of parts are detected. When the resistance values ​​of the plurality of parts exceed a preset resistance protection range, the syringe pump controls the flow rates of some or all of the injection passages so that the resistance values ​​of the plurality of parts are within the resistance protection range. The process of the syringe pump controlling the flow rates of some or all of the injection passages to control the resistance value may refer to the process of the syringe pump controlling the flow rates of some or all of the injection passages to control the temperature value.

[0057] In the embodiment of the present invention, a multi-passage injection structure is used. When an RF operation task is triggered, the syringe pump is controlled to open at least one injection channel to perform an injection operation at a preset initial flow rate. The control mode of the RF operation data is determined, and when the control mode of the RF operation data is a dual control mode, the temperature of the multiple parts of the RF operation object is obtained from time to time, and the syringe pump controls the opening and closing of some or all of the injection channels, or the syringe pump controls the flow rate of some or all of the injection channels to adjust the temperature. In addition, when the flow rate of the syringe pump reaches a temperature control limit value, the RF output power is controlled to control the temperature. After the temperature control is completed, the resistance of the RF operation object is detected, and when the resistance value of a certain part exceeds a preset resistance protection range, the flow rate of the syringe pump is controlled to control the resistance value of the certain part. When an RF operation task is performed, the temperature and resistance of the RF operation object are respectively controlled to improve the effect of RF operation and ensure the safety of RF operation, and the multiple injection channels of the syringe pump can be dynamically controlled according to the real-time changes in temperature and resistance of the multiple parts of the RF operation object. By appropriately adjusting the injection amount of the syringe pump according to the real-time changes in temperature and resistance of various parts of the RF operation target, it is possible to reduce delays in operation and operational errors caused by human judgment. In addition, it is possible to improve the speed, accuracy and appropriateness of injecting liquid when performing an RF operation task. As a result, it is possible to reduce damage caused by RF operation to the RF operation target and improve the safety of RF operation.

[0058] Referring to Fig. 5, Fig. 5 is a flow chart showing a method for controlling RF operation data according to another embodiment of the present invention. The method is used to control a syringe pump with multiple injection passages, such as the syringe pump 20 shown in Fig. 2 and Fig. 3. The method can be implemented by the syringe pump 20 in Fig. 1, or by the RF host 10 in Fig. 1, or by other computer equipment electrically connected to the syringe pump. For ease of explanation, they are collectively referred to as a control device. As shown in Fig. 5, the method for controlling RF operation data includes the following steps:

[0059] In step S501, when an RF operation task is triggered, the syringe pump is controlled to open any one of the injection passages, and the liquid is injected into the RF operation target at an initial flow rate through the opened injection passage.

[0060] In step S502, the RF operation catheter is controlled to perform RF operation on the RF operation target. If the control mode of the RF operation data is the dual control mode, the temperatures of multiple parts of the RF operation target are obtained continuously.

[0061] Specifically, the RF manipulation catheter is controlled to perform RF manipulation on the RF manipulation target, and the control mode of the RF manipulation data is determined. If the control mode of the RF manipulation data is a dual control mode, the temperatures of multiple parts of the RF manipulation target are obtained continuously by multiple temperature detection devices.

[0062] When an RF manipulation task is triggered, the control device controls the syringe pump to open one of the injection passages, and injects liquid into the RF manipulation target at an initial flow rate through the opened injection passage, and then controls the RF manipulation catheter to perform RF manipulation on the RF manipulation target, and continuously obtains the temperatures of multiple sites of the RF manipulation target through multiple temperature detection devices.

[0063] Before the RF manipulation catheter performs RF manipulation, the syringe pump is controlled to open any one of the injection passages, and a small amount of liquid can be injected into the RF manipulation target through the opened injection passage. This avoids the problem of being unable to control based on the resistance value when the initial resistance of a special RF manipulation target is too high. Also, by injecting a small amount of liquid into the RF manipulation target, it is possible to avoid any effect on the RF manipulation target.

[0064] For the details of steps S501 and S502 not described in this embodiment, reference can be made to the details of steps S401 and S402 described in the embodiment of FIG.

[0065] In step S503, it is determined whether a first temperature exists in the temperatures of the multiple locations acquired at any time.

[0066] The first temperature is greater than a preset maximum temperature, which can be appropriately set by a user and preset in the execution body of the method for controlling RF operation data according to the embodiment of the present invention.

[0067] If the first temperature exists, perform step S504, that is, determine whether the first injection passage is opened.

[0068] Specifically, if the first temperature exists in the temperatures of the multiple locations acquired at any time, it means that the temperature of a location of the RF manipulation object exceeds the temperature control limit value, which may cause damage to the RF manipulation object. In this case, it is necessary to reduce the temperature of the location by increasing the injection amount, so it is determined whether the first injection passage is opened. The first injection passage is used to inject liquid into the first location, and the first temperature is the temperature of the first location.

[0069] For example, the four temperature detectors T1-T4 are used to detect the temperatures of the four parts B1-B4 of the RF operation target, respectively, and the four temperature detectors T1-T4 correspond to the four injection passages C1-C4 of the syringe pump, respectively. If the preset maximum temperature is 90°C (Celsius), the temperatures that the four temperature detectors T1-T4 can detect are 89.7°C, 91°C, 89.9°C, and 90.5°C. In this case, based on the correspondence between the temperature detection device, the operating parts and the injection passages and the temperatures obtained at any time {(T1, B1, C1, 89.7°C), (T2, B2, C2, 91°C), (T3, B3, C3, 89.9°C), (T4, B4, C4, 90.5°C)} and the preset maximum temperature of 90°C, it can be determined that the first temperatures exceeding the temperature control limit value are 91°C and 90.5°C, the first parts that need to be lowered are B2 and B4, and the first injection passages that need to be controlled are C2 and C4.

[0070] When an RF operation task is triggered, the control device controls which of the injection passages of the syringe pump is opened, so it is necessary to determine whether the first injection passages C2 and C4 are opened.

[0071] The control device stores the identification information (e.g., numbers) of the injection passages of the syringe pump, and creates a predetermined log every time the control device controls the opening and closing of the injection passages of the syringe pump. The log contains at least the identification information, flow rate, and opening and closing time related to the current opening and closing control of the injection passage. The log can be used to determine which injection passages are currently open, and whether the first injection passages C2 and C4 can be opened.

[0072] If the first injection passage cannot be opened, step S505 is carried out to control the syringe pump to open the first injection passage, and the process returns to step S503.

[0073] Once the first injection passage is opened, execute step S506, which controls the syringe pump to increase the flow rate of the first injection passage with a preset first amplification, and return to step S503. Repeat step S506 until the flow rate of the first injection passage reaches the limit value of the preset temperature control flow rate.

[0074] Specifically, when the first injection passage is not opened, the syringe pump is controlled to open the first injection passage, liquid is injected through all the opened first injection passages, and the steps of determining whether the first temperature exists in the temperatures of the multiple sites acquired at any time are carried out.When the first injection passage is opened, the syringe pump is controlled to increase the flow rate of the first injection passage with a preset first amplification, and the steps of determining whether the first temperature exists in the temperatures of the multiple sites acquired at any time are carried out.The above steps are repeated until the flow rates of all the first injection passages reach the limit value of the preset temperature control flow rate.

[0075] In the first injection passages C2 and C4, when the first injection passage C2 is opened and the first injection passage C4 is not opened, the syringe pump is controlled to open the first injection passage C4, and the liquid can be injected into the site B4 at an initial flow rate through the first injection passage C4. Also, the syringe pump is controlled to increase the flow rate of the first injection passage C2 with a preset first amplification, thereby increasing the injection amount of the liquid injected into the site B2, and quickly lowering the temperatures of the sites B2 and B4.

[0076] If the first temperature does not exist, perform step S507 of determining whether the proportion of the first temperature detection device in the temperature detection device is greater than the first proportion.

[0077] Specifically, if there is no first temperature higher than the preset maximum temperature among the temperatures of the multiple locations obtained at any time, it means that the temperatures of the locations of the RF operation object are all within a safe range, and the current RF operation is unlikely to harm the RF operation object. Therefore, by determining whether the proportion of the first temperature detection device among the temperature detection devices is higher than the first proportion, it is determined whether the RF operation achieves the desired operation effect.

[0078] The preset temperature duration obtained by the first temperature detection device is less than the preset minimum temperature. The preset minimum temperature is the minimum temperature limit value at which a desired operation effect can be obtained. The preset minimum temperature, the preset duration and the first proportion can be appropriately set by a user and preset in the execution subject of the RF operation data control method according to the embodiment of the present invention.

[0079] If the ratio of the first temperature detector among the temperature detectors is greater than the first ratio, execute step S508 of controlling the syringe pump to decrease the flow rate of the first injection passage by a preset first decrease width, and return to step S507. Repeat step S508 until the flow rate of the second injection passage reaches the preset minimum flow rate.

[0080] If the proportion of the first temperature detector among the temperature detectors is not greater than the first proportion, the process returns to step S503.

[0081] Specifically, if the ratio of the first temperature detector in each temperature detector is greater than the first ratio, it means that the temperature of the entire RF manipulation object is low, the temperature amplification is small, and the amount of liquid injected is too large, and the desired manipulation effect cannot be achieved. In this case, the syringe pump reduces the flow rate of the second injection passage by a preset first reduction amount, and performs a step of determining whether the ratio of the first temperature detector in each temperature detector is greater than the first ratio, and repeats the step until the flow rate of the second injection passage reaches the preset minimum flow rate. The second injection passage is used to inject liquid into the second portion, and the first temperature detector is used to detect the temperature of the second portion.

[0082] The proportion of the first temperature detector among the temperature detectors is not greater than the first proportion, which means that the temperature rise rate of the RF operation object changes in a positive direction and the current amount of injected liquid supports the temperature rise of the RF operation object. Therefore, a step of determining whether the first temperature exists in the temperatures of the multiple locations obtained at various times is carried out.

[0083] As described above, by increasing or decreasing the amount of liquid injected according to the real-time changes in the temperature values ​​of each part, the accuracy of controlling the injection of liquid can be improved, the risk of operation can be reduced, and better operation effects can be achieved.

[0084] Assuming that the preset minimum temperature is 65°C (Celsius), the first proportion is 49%, and the preset duration is 10 seconds, the temperatures acquired by the four temperature detection devices T1 to T4 are 64.2°C (duration is 11 seconds), 64.3°C (duration is 9 seconds), 65.1°C (duration is 6 seconds) and 64.2°C (duration is 12 seconds), respectively. According to the correspondence relationship between the temperature detection device, the operation part and the injection passage and the temperature obtained at any time {(T1, B1, C1, 64.2°C, 11 seconds), (T2, B2, C2, 64.3°C, 9 seconds), (T3, B3, C3, 65.1°C, 6 seconds), (T4, B4, C4, 64.2°C, 12 seconds)} and the preset lowest temperature of 65°C, it can be understood that the first temperature detection device is T1 and T4, and the proportion of the first temperature detection device in each temperature detection device is 2 / 4=50% (which is greater than the first proportion 49%). In this case, it is necessary to control the first injection passages C1 and C4. That is, the syringe pump is controlled to reduce the flow rate of the first injection passages C1 and C4 by the preset first reduction width. Thereby, the injection amount of the liquid injected into the parts B1 and B4 can be reduced, and the effect of increasing the temperature of the parts B1 and B4 can be obtained.

[0085] In another embodiment of the present invention, each temperature detector sets a preset maximum temperature and a preset minimum temperature corresponding to each temperature detector, and determines the first injection passage and the second injection passage according to the preset maximum temperature and the preset minimum temperature corresponding to each temperature detector. Then, the above steps S503 to S508 are performed according to the first injection passage and the second injection passage determined according to the preset maximum temperature corresponding to each temperature detector.

[0086] Specifically, it is determined whether a first temperature exists among the temperatures of the multiple locations acquired at various times, and the first temperature is greater than a preset maximum temperature corresponding to the temperature detection device that detects the first temperature.

[0087] When it is determined that a first temperature exists in the temperatures of the multiple sites acquired at any given time, it is determined whether a first injection passage is opened. The first injection passage is used to inject liquid into the first site, and the first temperature is the temperature of the first site. When the first injection passage is not opened, the syringe pump is controlled to open the first injection passage, and a step of determining whether a first temperature exists in the temperatures of the multiple sites acquired at any given time is performed. The first temperature is greater than a preset maximum temperature corresponding to the temperature detection device that detected the first temperature. When the first injection passage is opened, the syringe pump is controlled to increase a flow rate of the first injection passage with a preset first amplification, and a step of determining whether a first temperature exists in the temperatures of the multiple sites acquired at any given time is performed. The first temperature is greater than a preset maximum temperature corresponding to the temperature detection device that detected the first temperature. The above steps are repeated until the flow rate of the first injection passage reaches a limit value of the preset temperature control flow rate.

[0088] If it is determined that the temperature of the multiple locations acquired at any given time does not include a first temperature, it is determined whether the ratio of the first temperature detection device in the temperature detection devices is greater than a first ratio. The preset temperature duration acquired by the first temperature detection device is less than a preset minimum temperature corresponding to the first temperature detection device. If it is determined that the ratio of the first temperature detection device is greater than the first ratio, the syringe pump reduces the flow rate of the second injection passage by a preset first decrease amount, and performs a step of determining whether the ratio of the first temperature detection device in each temperature detection device is greater than the first ratio, and repeats the step until the flow rate of the second injection passage reaches the preset minimum flow rate. The second injection passage is used to inject liquid into the second location, and the first temperature detection device is used to detect the temperature of the second location. If it is determined that the ratio of the first temperature detection device is not greater than the first ratio, it is determined whether the temperature of the multiple locations acquired at any given time includes a first temperature. The first temperature is greater than a preset maximum temperature corresponding to the temperature detection device that detected the first temperature.

[0089] Due to the different surface shapes, internal tissue structures, tissue thicknesses, etc. of different parts of the RF operation target, the temperature changes corresponding to the output of RF energy are different, and the temperature limit values ​​that bring about qualitative changes are also different. By appropriately controlling the injection operation according to the maximum limit value and the minimum limit value obtained by the multiple temperature detection devices corresponding to the various parts of the RF operation target, the accuracy of the injection operation can be improved and the effect of the operation can be ensured.

[0090] In step S509, if the flow rate of the syringe pump reaches the temperature control limit value but the temperature values ​​of the multiple locations are still outside the temperature protection range, the RF output power is controlled so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0091] In the above step, the RF operation target is controlled by adjusting the flow rate of the liquid injected. When the flow rate of the syringe pump reaches the temperature control limit value but the temperature values ​​of the multiple locations are still outside the temperature protection range, the method of controlling the temperature by changing the flow rate is not adopted. In this case, the temperature is controlled by controlling the RF output power so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0092] In step S510, the resistance values ​​of the multiple sites are detected, and when the resistance values ​​of the multiple sites exceed a preset resistance protection range, the syringe pump is controlled to control the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites fall within the resistance protection range.

[0093] When the temperature is controlled to be normal, i.e., when the temperature value is within the temperature protection range, one or more resistance detection devices detect the resistance values ​​of the multiple sites, respectively. When the resistance values ​​of the multiple sites exceed the preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages to make the resistance values ​​of the multiple sites fall within the resistance protection range.

[0094] In an embodiment of the present invention, when an RF operation task is triggered, the syringe pump is controlled to open one of the injection passages, and the opened injection passage is used to inject liquid into the RF operation target at an initial flow rate. The control mode of the RF operation data is determined, and when the control mode of the RF operation data is a dual control mode, the syringe pump is controlled to open or close some or all of the injection passages, or to control the flow rate of some or all of the injection passages according to the temperatures of the multiple parts of the RF operation target obtained from the multiple temperature detection devices at any time. In addition, when the flow rate of the syringe pump reaches a temperature control limit value, the RF output power is controlled to control the temperature. After the temperature control is completed, the resistance of the RF operation target is detected, and when the resistance value of a specific part exceeds a preset resistance protection range, the flow rate of the syringe pump is controlled to control the resistance value of the specific part. When the RF operation task is performed, the temperature and resistance of the RF operation target are respectively controlled to improve the effect of RF operation and ensure the safety of RF operation, and the multiple injection passages of the syringe pump can be dynamically controlled according to the real-time changes in temperature and resistance of multiple parts of the RF operation target. By appropriately adjusting the injection amount of the syringe pump according to the real-time changes in temperature and resistance of various parts of the RF operation target, it is possible to reduce delays in operation and operational errors caused by human judgment. In addition, it is possible to improve the speed, accuracy and appropriateness of injecting liquid when performing an RF operation task. As a result, it is possible to reduce damage caused by RF operation to the RF operation target and improve the safety of RF operation.

[0095] Referring to Fig. 6, Fig. 6 is a flow chart showing a method for controlling RF operation data according to another embodiment of the present invention. The method is used to control a syringe pump with multiple injection passages, such as the syringe pump 20 shown in Fig. 2 and Fig. 3. The method can be performed by the syringe pump 20 in Fig. 1, or by the RF host 10 in Fig. 1, or by other computer equipment electrically connected to the syringe pump. For ease of explanation, they are collectively referred to as a control device. Fig. 6 shows the method for controlling RF operation data, which includes the following steps:

[0096] In step S601, when an RF operation task is triggered, the syringe pump is controlled to open any one of the injection passages, and the liquid is injected into the RF operation target at an initial flow rate through the opened injection passage.

[0097] In step S602, the RF operation catheter is controlled to perform RF operation on the RF operation target. If the control mode of the RF operation data is the dual control mode, the temperatures of multiple parts of the RF operation target are obtained continuously.

[0098] The RF operation catheter is controlled to perform RF operation on the RF operation object, and a control mode of the RF operation data is determined. When the control mode of the RF operation data is a dual control mode, the temperatures of multiple parts of the RF operation object are obtained continuously by multiple temperature detection devices.

[0099] Steps S601 and S602 are the same as steps S501 and S502 in the embodiment of FIG. 5, and the description of the embodiment of FIG. 5 can be referred to, so they will not be described again here.

[0100] In step S603, it is determined whether the proportion of the second temperature is greater than the second proportion in the temperatures of the multiple locations acquired at random.

[0101] The second temperature is greater than the preset maximum temperature. The second proportion can be appropriately set by a user and can be preset in the execution body of the method for controlling RF operation data according to the embodiment of the present invention.

[0102] If the proportion of the second temperature is greater than the second proportion, step S604 is performed to determine the injection increase according to the preset increase rule.

[0103] Specifically, if the proportionality of the second temperature, which is higher than the preset maximum temperature, is greater than the second proportionality among the temperatures of the multiple regions acquired at any time, it means that the temperature of the entire RF operation target is high and there is a risk of damage, in which case the amount of liquid injected should be increased to lower the temperature of the specified region, and the injection increase should be determined according to the preset increase rule (i.e., the injection amount should be increased).

[0104] The preset dose increase rule determines the dose increase according to the difference between the maximum temperature of the temperatures of the multiple sites and the preset maximum temperature. The difference between the maximum temperature of the temperatures of the multiple sites and the preset maximum temperature is directly proportional to the dose increase. That is, the greater the difference between the maximum temperature of the temperatures of the multiple sites and the preset maximum temperature, the greater the dose increase that is required to increase the dose.

[0105] The injection increment and the injection decrement can be appropriately set by the user and can be fixed values ​​preset in the control device.

[0106] Specifically, the control device can preset a correspondence relationship between a plurality of difference intervals and a preset injection amount increase. First, it is determined which difference interval the maximum temperature of the temperatures of the plurality of parts falls into. Next, the injection amount increase falling into the difference interval is set to the desired injection amount according to the difference interval in which the maximum temperature falls and the correspondence relationship.

[0107] In step S605, the open standby quantity is determined according to the injection increment and the initial flow rate, and the third injection passage is determined according to the open standby quantity and the first determination rule.

[0108] As is well known, the initial flow rate of each injection passage is the same, and each time the syringe pump opens an injection passage, it performs an injection operation at the preset initial flow rate through the opened injection passage.

[0109] Specifically, the first determination rule is to determine the third injection passage according to the distance between the injection passage and the second temperature detection device, the number of open waiting, and the order from the closest to the furthest. The temperature obtained by the second temperature detection device is the highest temperature. When there are multiple injection passages at the same distance from the second temperature detection device, the required third injection passage can be determined randomly from the multiple injection passages.

[0110] The formula for determining the open waiting quantity according to the injection increment and the initial flow rate is, for example, injection increment / initial flow rate+1.

[0111] In the present embodiment, referring to FIG. 8, the six temperature detectors T1-T6 are provided, which correspond to the six regions B1-B6 of the RF operation target, and the six injection passages C1-C6 of the syringe pump inject liquid into the six regions B1-B6. When the preset maximum temperature is 90°C and the second proportion is 50%, the temperatures acquired by the six temperature detectors T1-T6 at any given time are 90.2°C, 80.9°C, 90.1°C, 90.3°C, 80.8°C, and 90.3°C, respectively, and the four second temperatures are 90.2°C, 90.1°C, 90.3°C, and 90.3°C, respectively. The proportion between the quantity of the second temperatures and the quantity of the temperatures acquired by the six temperature detectors T1-T6 is 4 / 6≒67%, which is greater than the second proportion of 50%. The desired injection increment (e.g., 0.5 ml) is determined according to the difference between the maximum temperature of the six temperatures, 90.3°C, and the preset maximum temperature of 90°C, which is 0.3°C, and the corresponding relationship between a number of difference intervals and the preset injection increment. Next, the open standby quantity determined according to the initial flow rate of each injection passage (e.g., 0.2 ml) and the determined injection increment is [(0.5 / 0.2)]+1=3. Finally, the third injection passages determined according to the distance between the injection passage and the second temperature detection device T6 (the temperature acquired by the second temperature detection device T6 is the highest), the open standby quantity, and the order from the closest to the furthest are C5, C1, and C2, respectively.

[0112] In step S606, the syringe pump is controlled to open the third injection passage, and then the process returns to step S603. The process repeats this step until all the injection passages are opened.

[0113] The control device stores the identification information of the injection passages of the syringe pump, controls the syringe pump to open the third injection passage according to the identification information, and performs a step of determining whether the proportion of the second temperature is greater than the second proportion in the temperatures of the multiple sites obtained at any time, and repeats the step until all the injection passages are opened.

[0114] The control device forms a certain log every time it controls the opening and closing of the injection passage of the syringe pump. The log contains at least the label information, flow rate, and opening and closing time related to the current opening and closing control of the injection passage. Before controlling the syringe pump to open the third injection passage, it can determine whether the third injection passage can be opened based on the log. If the third injection passage cannot be opened, the third injection passage is opened, and when the third injection passage is opened, other injection passages adjacent to the third injection passage are opened. For example, when the injection passage C2 is opened, the injection passage C3 adjacent to the injection passage C2 is opened. When the injection passage C3 is also opened, the injection passage C4 adjacent to the injection passage C3 is opened. The steps are repeated until all the injection passages are opened, or until the number of the third injection passages that can be opened reaches the open standby number.

[0115] If all the injection passages are opened but the proportion of the second temperature is still greater than the second proportion, it means that the injection control effect is not good and the temperature of the whole RF operation object is too high. In this case, the syringe pump controls the flow rate of all the injection passages to increase to the limit value of the preset temperature control flow rate to obtain a rapid cooling effect.

[0116] If the proportion of the second temperature is not greater than the second proportion, then perform step S607 of determining whether the proportion of a third temperature sensing device among the temperature sensing devices is greater than a third proportion.

[0117] Specifically, if the proportion of the second temperature, which is greater than the preset maximum temperature, is not greater than the second proportion in the temperatures of the multiple locations acquired at any time, it means that the temperature of the entire RF operation object is within a safe range, and there is no risk of the current RF operation damaging the RF operation object. In this case, by determining whether the proportion of the third temperature detection device in each temperature detection device is greater than the third proportion, it is ensured that the RF operation achieves the desired operation effect. The temperature acquired by the third temperature detection device is less than the preset minimum temperature. The third proportion can be appropriately set by the user and preset in the execution body of the RF operation data control method according to the embodiment of the present invention.

[0118] If the proportion of the third temperature detection device is greater than the third proportion, step S608 is carried out to determine the injection reduction according to the preset reduction rule.

[0119] In each temperature detection device, if the ratio of the third temperature detection device is greater than the third ratio, it means that the temperature of the entire RF operation object is low and the amount of liquid injected is too large, which cannot achieve the desired operation effect. In this case, it is necessary to determine the injection amount reduction according to the preset reduction rule.

[0120] The preset weight reduction rule determines the injection weight reduction according to the difference between the lowest temperature of the temperatures of the multiple sites and the preset lowest temperature. The difference between the lowest temperature of the temperatures of the multiple sites and the preset lowest temperature is directly proportional to the injection weight reduction. That is, the greater the difference between the lowest temperature of the temperatures of the multiple sites and the preset lowest temperature, the greater the injection weight reduction that is required to reduce the injection weight.

[0121] Specifically, the control device can preset a correspondence relationship between a plurality of difference intervals and a preset injection amount reduction. First, it is determined which difference interval the lowest temperature among the temperatures of the plurality of parts falls into. Next, the injection amount increase falling into the difference interval is set to the desired injection amount reduction according to the difference interval in which the lowest temperature falls and the correspondence relationship.

[0122] In step S609, the off-standby quantity is determined according to the injection reduction amount and the initial flow rate, and the fourth injection passage is determined according to the off-standby quantity and the second determination rule.

[0123] Specifically, the formula for determining the off standby quantity according to the injection reduction and the initial flow rate is, for example, injection reduction / initial flow rate+1.

[0124] The second determination rule is to determine the fourth injection passage according to the distance between the injection passage and the fourth temperature detection device, the order from the nearest to the furthest, and the number of off standbys. The temperature obtained by the fourth temperature detection device is the lowest temperature.

[0125] The method of determining the fourth injection passage is similar to the method of determining the third injection passage, and the method of determining the fourth injection passage can refer to the given description in step S605, so it will not be described again here.

[0126] In step S610, the syringe pump is controlled to close the fourth injection passages, and then the process returns to step S607. The process repeats this step until all the fourth injection passages are closed.

[0127] The control device controls the syringe pump to close the fourth injection passage according to the mark information of each injection passage, and performs a step of determining whether the proportion of the third temperature detection device among each temperature detection device is greater than the third proportion, and repeats the step until all injection passages are closed.

[0128] When a fourth injection passage that needs to be closed is closed, close the injection passage adjacent to the fourth injection passage. When the adjacent injection passage is also closed, close the next injection passage adjacent to that injection passage. Repeat the steps until all injection passages are closed or until the number of fourth injection passages that are closed reaches the off standby quantity.

[0129] If the proportion of the third temperature detecting device is not greater than the third proportion in all the temperature detecting devices, perform step S603, that is, determine whether the proportion of the second temperature is greater than the second proportion in the temperatures of the multiple locations obtained at random.

[0130] As described above, by increasing or decreasing the amount of liquid injected according to the real-time changes in the temperature values ​​of each part, the accuracy of controlling the injection of liquid can be improved, the risk of operation can be reduced, and better operation effects can be achieved.

[0131] In step S611, if the flow rate of the syringe pump reaches the temperature control limit value but the temperature values ​​of the multiple locations are still outside the temperature protection range, the RF output power is controlled so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0132] In the above step, the RF operation target is controlled by adjusting the flow rate of the liquid injected. When the flow rate of the syringe pump reaches the temperature control limit value, the method of controlling the temperature by changing the flow rate is not adopted. In this case, the temperature is controlled by controlling the RF output power so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0133] In step S612, the resistance values ​​of the multiple sites are detected, and when the resistance values ​​of the multiple sites exceed a preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites fall within the resistance protection range.

[0134] When the temperature is controlled to be normal, i.e., when the temperature value is within the temperature protection range, the resistance values ​​of the plurality of parts are detected, and when the resistance values ​​of the plurality of parts exceed the preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages so that the resistance values ​​of the plurality of parts are within the resistance protection range.

[0135] For matters not described in this embodiment, please refer to the description in the embodiment of FIG. 4 and FIG.

[0136] In an embodiment of the present invention, when an RF operation task is triggered, the syringe pump is controlled to open one of the injection passages, and the opened injection passage is used to inject liquid at an initial flow rate. The control mode of the RF operation data is determined, and when the control mode of the RF operation data is a dual control mode, the syringe pump is controlled to open or close some or all of the injection passages, or to control the flow rate of some or all of the injection passages according to the temperatures of the multiple parts of the RF operation object obtained from the multiple temperature detection devices at any time. In addition, when the flow rate of the syringe pump reaches a temperature control limit value, the RF output power is controlled to control the temperature. After the temperature control is completed, the resistance of the RF operation object is detected, and when the resistance value of the predetermined part exceeds a preset resistance protection range, the flow rate of the syringe pump is controlled to control the resistance value of the predetermined part. When the RF operation task is performed, the temperature and resistance of the RF operation object are respectively controlled to improve the effect of the RF operation and ensure the safety of the RF operation, and the multiple injection passages of the syringe pump can be dynamically controlled according to the real-time changes in the temperature and resistance of the multiple parts of the RF operation object. By appropriately adjusting the injection amount of the syringe pump according to the real-time changes in temperature and resistance of various parts of the RF operation target, it is possible to reduce delays in operation and operational errors caused by human judgment. In addition, it is possible to improve the speed, accuracy and appropriateness of injecting liquid when performing an RF operation task. As a result, it is possible to reduce damage caused by RF operation to the RF operation target and improve the safety of RF operation.

[0137] Referring to Fig. 7, Fig. 7 is a flow chart showing a method for controlling RF operation data according to another embodiment of the present invention. The method is used to control a syringe pump with multiple injection passages, such as the syringe pump 20 shown in Fig. 2 and Fig. 3. The method can be performed by the syringe pump 20 of Fig. 1, or by the RF host 10 of Fig. 1, or by other computer equipment electrically connected to the syringe pump. For ease of explanation, they are collectively referred to as a control device. Fig. 7 shows the method for controlling RF operation data, which includes the following steps:

[0138] In step S701, when an RF operation task is triggered, the RF operation catheter is controlled to perform RF operation.

[0139] Specifically, the RF operation task can be triggered by a trigger command sent by another control device when a preset trigger time is reached, or by detecting an operation of a user to trigger the RF operation task. The operation of triggering the RF operation task can be, for example, a user pressing a physical button or a virtual button to trigger the RF operation task.

[0140] Each time the syringe pump is started, it sets the injection parameters to pre-defined initial values, which may include, but are not limited to, initial flow rate, total injection volume, injection time, etc.

[0141] When an RF manipulation mission is triggered, the RF manipulation catheter outputs RF energy to the RF manipulation target by performing RF manipulation on the RF manipulation target.

[0142] In step S702, after waiting for a preset time, the syringe pump is controlled to open all the injection passages, and liquid is injected into the RF operation target at an initial flow rate through the opened injection passages.

[0143] Specifically, the preset duration can be appropriately set by a user and preset to the executing entity of the method for controlling RF operation data according to the embodiment of the present invention.

[0144] As is well known, if the temperature of the RF operation target does not rise to a predetermined temperature, the desired operation effect cannot be achieved. After the RF operation catheter is controlled to perform RF operation, a preset time is waited. When the temperature of the RF operation target rises to a predetermined temperature, the syringe pump opens all the injection passages to perform the injection operation. This avoids affecting the temperature rise of the RF operation target due to early injection, and ensures a good operation effect.

[0145] In step S703, the RF operation catheter is controlled to perform RF operation on the RF operation target. If the control mode of the RF operation data is the dual control mode, the temperatures of multiple parts of the RF operation target are obtained continuously.

[0146] When the RF manipulation catheter is controlled to perform RF manipulation on the RF manipulation target, and the control mode of the RF manipulation data is a dual control mode, the temperatures of multiple parts of the RF manipulation target are obtained continuously by multiple temperature detection devices.

[0147] Step S703 can refer to the description of step S402 in the embodiment of FIG. 4, so it will not be described again here.

[0148] In step S704, it is determined whether the third temperature ratio is greater than the fourth temperature ratio in the temperatures of the multiple locations obtained at random.

[0149] If the third temperature proportionality is greater than the fourth proportionality, step S705 is performed to close any injection passages that have been opened, and then the process returns to step S704.

[0150] Specifically, the third temperature is less than the preset minimum temperature. If the proportion of the third temperature, which is less than the preset minimum temperature, is greater than the fourth proportion in the temperatures of the multiple locations obtained, it means that the current injection amount is large and the temperature of the entire RF operation target does not reach the desired temperature. In this case, the amount of liquid injected is reduced by closing any of the opened injection passages, and a step of determining whether the proportion of the third temperature is greater than the fourth proportion in the temperatures of the multiple locations obtained at any time is repeated until all injection passages are closed.

[0151] If the proportion of the third temperature is not greater than the fourth proportion, then perform step S706 of determining whether the proportion of the fourth temperature is greater than the fifth proportion in the temperatures of the multiple portions obtained at random.

[0152] If the fourth temperature ratio is greater than the fifth temperature ratio, perform step S707 of determining whether there is an unopened injection passage.

[0153] When there is an injection passage that cannot be opened, step S708 is performed to open any of the injection passages that cannot be opened, and then the process returns to step S706. This step is repeated until all the injection passages are opened.

[0154] If there are no injection passages that cannot be opened, step S709 is performed to increase the flow rate of each injection passage by a preset second amplification, and then the process returns to step S706. The process is repeated until the flow rate of the injection passage reaches the preset temperature control flow rate limit value.

[0155] If the fourth temperature proportion is not greater than the fifth proportion, step S704 is performed.

[0156] Specifically, in the temperatures of the multiple locations acquired at any time, if the proportion of the third temperature, which is lower than the preset minimum temperature, is not greater than the fourth proportion, it means that the temperature of the entire RF operation object reaches the desired temperature, and the current amount of liquid injected can support the temperature rise of the RF operation object. In this case, in order to avoid the RF operation object being damaged due to the temperature being too high, it is determined whether the proportion of the fourth temperature is greater than the fifth proportion in the temperatures of the multiple locations acquired. The fourth temperature is greater than the preset maximum temperature. The fourth proportion and the fifth proportion can be appropriately set by the user, and can be preset in the execution body of the RF operation data control method according to the embodiment of the present invention.

[0157] If the proportion of the fourth temperature is greater than the fifth proportion in the temperatures of the multiple locations acquired, it means that the temperature of the RF operation target is too high, which may cause a risk of injury to the RF operation target. In this case, it is necessary to determine whether there is an injection passage that cannot be opened in order to increase the amount of liquid injected and reduce the temperature of a certain location. If there is an injection passage that cannot be opened, open one of the injection passages that cannot be opened, and perform a step of determining whether the proportion of the fourth temperature is greater than the fifth proportion in the temperatures of the multiple locations acquired at any time, and repeat the step until all the injection passages are opened. When all the injection passages are opened, increase the flow rate of the injection passage with a preset second amplification, and perform a step of determining whether the proportion of the fourth temperature is greater than the fifth proportion in the temperatures of the multiple locations acquired at any time, and repeat the step until the flow rate of the injection passage reaches a preset limit value of the temperature control flow rate. When the flow rate of the injection passage reaches a preset limit value of the temperature control flow rate, but the proportion of the fourth temperature is still greater than the fifth proportion in the temperatures of the multiple locations acquired at any time, an early warning is output.

[0158] If the proportion of the fourth temperature is not greater than the fifth proportion in the temperatures of the multiple locations acquired at any given time, a step of determining whether the proportion of the third temperature is greater than the fourth proportion in the temperatures of the multiple locations acquired at any given time is performed.

[0159] As described above, by increasing or decreasing the amount of liquid injected according to the real-time changes in the temperature values ​​of each part, the accuracy of controlling the injection of liquid can be improved, the risk of operation can be reduced, and better operation effects can be achieved.

[0160] In step S710, if the flow rate of the syringe pump reaches the limit value of the preset temperature control flow rate but the temperature values ​​of the multiple locations are still outside the temperature protection range, the RF output power is controlled so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0161] In the above step, the RF operation target is controlled by adjusting the flow rate of the liquid injected. When the flow rate of the syringe pump reaches the temperature control limit value, the method of controlling the temperature by changing the flow rate is not adopted. In this case, the temperature is controlled by controlling the RF output power so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0162] In step S711, the resistance values ​​of the multiple sites are detected, and when the resistance values ​​of the multiple sites exceed a preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites fall within the resistance protection range.

[0163] When the temperature is controlled to be normal, i.e., when the temperature value is within the temperature protection range, the resistance values ​​of the plurality of parts are detected, and when the resistance values ​​of the plurality of parts exceed the preset resistance protection range, the syringe pump controls the flow rate of some or all of the injection passages so that the resistance values ​​of the plurality of parts are within the resistance protection range.

[0164] For matters not described in this embodiment, the explanations in the embodiment of Figs. 4 to 6 can be referred to.

[0165] In the embodiment of the present invention, when an RF operation task is triggered, first, the RF operation catheter is controlled to perform RF operation. Then, after waiting for a preset time, the syringe pump is controlled to open all the injection passages, and the liquid is injected into the RF operation target at an initial flow rate through the opened injection passages. The control mode of the RF operation data is determined. If the control mode of the RF operation data is a dual control mode, the syringe pump controls the opening and closing of some or all of the injection passages, or controls the flow rate of some or all of the injection passages according to the temperatures of the multiple parts of the RF operation target obtained from the multiple temperature detection devices at any time. In addition, when the flow rate of the syringe pump reaches the temperature control limit value, the RF output power is controlled to control the temperature. After the temperature control is completed, the resistance of the RF operation target is detected, and when the resistance value of a specific part exceeds the preset resistance protection range, the flow rate of the syringe pump is controlled to control the resistance value of the specific part. When performing an RF operation task, the temperature and resistance of the RF operation target are controlled respectively, thereby improving the effect of RF operation and ensuring the safety of RF operation. Multiple injection paths of the syringe pump can be dynamically controlled according to real-time changes in temperature values ​​of multiple parts of the RF operation target. Operation delays and operational errors due to artificial judgment can be reduced by appropriately adjusting the injection amount of the syringe pump according to real-time changes in temperature values ​​of various parts of the RF operation target. In addition, when performing an RF operation task, the speed, accuracy and appropriateness of injecting liquid can be improved. As a result, damage caused by RF operation to the RF operation target can be reduced and the safety of RF operation can be improved.

[0166] Referring to FIG. 9, FIG. 9 is a diagram showing the structure of a control device for a plurality of injection passages of a syringe pump according to an embodiment of the present invention. For the sake of simplicity, FIG. 9 shows only parts according to the embodiment of the present invention. The control device for a plurality of injection passages of a syringe pump can be implemented by the syringe pump 20, the RF host 10 or other computer terminals in FIG. 1, or can be implemented by a virtual module of the device. The control device for a plurality of injection passages of a syringe pump is used to control a syringe pump having a plurality of injection passages. The control device for a plurality of injection passages of a syringe pump includes a control module 901, a confirmation module 902, a temperature detection module 903 and a resistance detection module 904.

[0167] The control module 901 controls the syringe pump to open at least one injection passage when an RF operation mission is triggered, and performs an injection operation at a preset initial flow rate through the opened injection passage.

[0168] The validation module 902 determines the control mode of the RF operational data.

[0169] When the control mode of the RF operation data is a dual control mode, the temperature detection module 903 continuously obtains temperature values ​​of a plurality of parts of the RF operation target.

[0170] The control module 901 controls the syringe pump to open or close some or all of the injection passages according to real-time changes in the temperature values ​​of the multiple sites when the temperature values ​​of the multiple sites exceed a preset temperature protection range, or controls the syringe pump to control the flow rate of some or all of the injection passages according to real-time changes in the temperature values ​​of the multiple sites.

[0171] When the flow rate of the syringe pump reaches a preset temperature control limit value but the temperature values ​​of the multiple locations are still outside the temperature protection range, the control module 901 controls the RF output power so that the temperature values ​​of the multiple locations are within the temperature protection range.

[0172] The resistance detection module 904 detects the resistance values ​​of the multiple locations.

[0173] When the resistance values ​​of the multiple sites exceed a preset resistance protection range, the control module 901 controls the syringe pump to control the flow rate of some or all of the injection passages so that the resistance values ​​of the multiple sites fall within the resistance protection range.

[0174] The confirmation module 902 obtains setting information for the user to set the data control mode. If the user sets the data control mode, the control mode of the RF operation data is determined according to the user's setting. The data control mode is one of a temperature single control mode, a resistance single control mode, and a dual control mode. If the user does not set the data control mode, the control mode of the RF operation data is the dual control mode.

[0175] The control module 901 includes a first control sub-module that controls the syringe pump to open any one of the injection passages when an RF operation task is triggered, and injects liquid into the RF operation target at an initial flow rate through the opened injection passage, and the first control sub-module controls the RF operation catheter to perform RF operation on the RF operation target.

[0176] The control module 901 further includes a second control sub-module, the second control sub-module being: determining whether a first temperature exists among the temperatures of the plurality of locations acquired at any one time, the first temperature being greater than a preset maximum temperature; determining whether a first injection passage is opened if a first temperature is determined to exist, the first injection passage being used to inject liquid into a first portion, and the first temperature being a temperature of the first portion; If the first injection passage is not opened, control the syringe pump to open the first injection passage, and determine whether a first temperature exists in the temperatures of the plurality of sites acquired at regular intervals; When the first injection passage is opened, the method further includes a step of controlling the syringe pump to increase the flow rate of the first injection passage with a preset first amplification, and determining whether a first temperature exists in the temperatures of multiple sites acquired at any time, and repeating the step until the flow rate of the first injection passage reaches a limit value of a preset temperature control flow rate.

[0177] The control submodule determines whether a first temperature exists in the temperatures of the plurality of locations, and when it is determined that the first temperature does not exist, determines whether a proportion of a first temperature detection device in the temperature detection devices is greater than a first proportion, and a preset temperature duration obtained by the first temperature detection device is less than a preset minimum temperature; when it is determined that the proportion of a first temperature detector in the temperature detectors is greater than the first proportion, the syringe pump reduces the flow rate of the second injection passage by a preset first reduction amount, and performs a step of determining whether the proportion of the first temperature detector in each temperature detector is greater than the first proportion, and repeating the steps until the flow rate of the second injection passage reaches a preset minimum flow rate, wherein the second injection passage is used to inject liquid into a second portion, and the first temperature detector is used to detect the temperature of the second portion; If it is determined that the proportion of the first temperature detection device is not greater than the first proportion, the step of determining whether the first temperature exists in the temperatures of the multiple locations acquired at various times is further carried out.

[0178] The control device of the multiple injection passages of the syringe pump further includes a setting module for setting a preset maximum temperature and a preset minimum temperature corresponding to each temperature detection device, and the second control sub-module determines the first injection passage and the second injection passage according to the preset maximum temperature and the preset minimum temperature corresponding to each temperature detection device.

[0179] The control module 901 further includes a third control sub-module, determining whether a proportion of a second temperature is greater than a second proportion among the temperatures of the plurality of locations acquired at regular intervals, the second temperature being greater than a preset maximum temperature; determining an injection increase according to a preset increase rule if the proportion of the second temperature is greater than a second proportion; determining an open standby quantity according to the injection increment and an initial flow rate, and determining a third injection passage according to the open standby quantity and a first determination rule; The method further includes the steps of controlling the syringe pump to open a third injection passage, determining whether the proportion of the second temperature is greater than the second proportion in the temperatures of multiple locations acquired at any given time, and repeating the steps until all injection passages are opened, and when the third injection passage is opened, opening other injection passages adjacent to the third injection passage.

[0180] The third control sub-module controls the syringe pump to increase the flow rates of all injection passages up to a preset temperature controlled flow rate limit value when all injection passages are opened but the proportion of the second temperature is still greater than the second proportion.

[0181] The preset increase rule determines the injection increase according to the difference between the highest temperature among the temperatures of multiple locations and the preset highest temperature. The difference between the highest temperature and the preset highest temperature is directly proportional to the injection increase. The first determination rule determines the third injection passage according to the distance between the injection passage and the second temperature detection device, the number of open waiting, and the order from the closest location to the furthest location. The temperature obtained by the second temperature detection device is the highest temperature.

[0182] The third control sub-module: if the proportion of the second temperature is not greater than the second proportion, determining whether the proportion of a third temperature sensing device in each temperature sensing device is greater than a third proportion, where the temperature acquired by the third temperature sensing device is less than a preset minimum temperature; determining an injection reduction according to a preset reduction rule when the proportion of the third temperature detection device is greater than a third proportion; determining an off standby quantity according to the injection reduction amount and an initial flow rate, and determining a fourth injection passage according to the off standby quantity and a second determination rule; controlling the syringe pump to close the fourth injection passage, determining whether the proportion of the third temperature detection device in each temperature detection device is greater than the third proportion, and repeating the steps until all injection passages are closed, and when the fourth injection passage is closed, closing the injection passage adjacent to the fourth injection passage; If the proportion of the third temperature detecting device is not greater than the third proportion, the step of determining whether the proportion of the second temperature is greater than the second proportion in the temperatures of the multiple locations obtained at different times is further performed.

[0183] The preset weight loss rule determines the injection weight loss according to the difference between the lowest temperature among the temperatures of the plurality of portions and a preset lowest temperature, and the difference between the lowest temperature and the preset lowest temperature is directly proportional to the injection weight loss. The second determination rule is to determine the fourth injection passage according to the distance between the injection passage and the fourth temperature detection device, the order from the nearest to the furthest, and the number of off standbys. The temperature obtained by the fourth temperature detection device is the lowest temperature.

[0184] The control module 901 further includes a fourth control sub-module for controlling the RF operation catheter to perform RF operation when an RF operation task is triggered; The fourth control submodule waits a preset time, and then controls the syringe pump to open all the injection passages, and injects liquid into the RF operation target at an initial flow rate through the opened injection passages.

[0185] The fourth control submodule: determining whether a third temperature ratio is greater than a fourth temperature ratio in the temperatures of the plurality of locations acquired at random, the third temperature being less than a preset minimum temperature; If the third temperature ratio is greater than the fourth ratio, closing any of the opened injection passages, determining whether the third temperature ratio is greater than the fourth ratio at the temperatures of the multiple locations obtained at any time, and repeating the steps until all of the injection passages are closed; if the third temperature ratio is not greater than the fourth ratio, determining whether the fourth temperature ratio is greater than the fifth ratio in the temperatures of the multiple locations acquired at random, where the fourth temperature is greater than a preset maximum temperature; determining whether there is an unopened injection passage when the fourth temperature ratio is greater than the fifth temperature ratio; When there is an injection passage that cannot be opened, opening any of the injection passages that cannot be opened, determining whether the fourth temperature ratio is greater than the fifth temperature ratio in the temperatures of the multiple locations obtained at any time, and repeating the steps until all the injection passages are opened; if there is no unopened injection passage, increasing the flow rate of the injection passage by a preset second amplification, determining whether the proportion of the fourth temperature is greater than the fifth proportion in the temperatures of the multiple locations obtained at any time, and repeating this step until the flow rate of the injection passage reaches a limit value of the preset temperature control flow rate; If the proportion of the fourth temperature is not greater than the fifth proportion, the step of determining whether the proportion of the third temperature is greater than the fourth proportion in the temperatures of the multiple portions acquired at any given time is further carried out.

[0186] The specific process by which each module realizes a predetermined function can be referred to in the description of the embodiment of FIG. 4 to FIG. 9, so it will not be described again here.

[0187] In the embodiment of the present invention, an injection structure with multiple passages is used. When an RF operation task is triggered, the syringe pump is controlled to open at least one injection passage to perform an injection operation at a preset initial flow rate. The control mode of the RF operation data is determined. When the control mode of the RF operation data is a dual control mode, the syringe pump controls the opening and closing of some or all of the injection passages, or controls the flow rate of some or all of the injection passages according to the temperatures of the multiple parts of the RF operation object obtained from the multiple temperature detection devices at any time. In addition, when the flow rate of the syringe pump reaches a temperature control limit value, the RF output power is controlled to control the temperature. After the temperature control is completed, the resistance of the RF operation object is detected, and when the resistance value of a certain part exceeds a preset resistance protection range, the flow rate of the syringe pump is controlled to control the resistance value of the certain part. When the RF operation task is performed, the temperature and resistance of the RF operation object are respectively controlled to improve the effect of the RF operation and ensure the safety of the RF operation, and the multiple injection passages of the syringe pump can be dynamically controlled according to the real-time changes in the temperature and resistance of the multiple parts of the RF operation object. By appropriately adjusting the injection amount of the syringe pump according to the real-time changes in temperature and resistance of various parts of the RF operation target, it is possible to reduce delays in operation and operational errors caused by human judgment. In addition, it is possible to improve the speed, accuracy and appropriateness of injecting liquid when performing an RF operation task. As a result, it is possible to reduce damage caused by RF operation to the RF operation target and improve the safety of RF operation.
