[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0027] The energy device for tissue coagulation and its control method, apparatus and storage medium according to the embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] Figure 1 4 is a flow chart of a method for controlling an energy device for tissue coagulation according to an embodiment of the present invention.

[0029] like Figure 1 As shown, a method for controlling an energy device for tissue coagulation may include:

[0030] S11: In the process of controlling the energy device to output the target energy to coagulate the target tissue, the loop current between the energy device and the target tissue is obtained, and the change trend of the loop current is obtained.

[0031] Specifically, the energy device may be an electric energy device used during medical surgery. The electric energy device generates voltage and current of corresponding frequency through a generator, which is transmitted to the active electrode. The active electrode generates corresponding temperature on the tissue. After achieving the desired effect (coagulation or cutting), the current flows back through the ground electrode. Common electric energy devices include but are not limited to single-stage electric knives, bipolar electric devices and radiofrequency ablation devices. The target energy may be the current, voltage or power output by the electric energy device, and the target tissue may be the biological tissue of the patient undergoing surgery during medical surgery. Coagulation can be understood as the operation of performing physiological hemostasis on biological tissue during medical surgery.

[0032] In medical surgery, the target tissue can be coagulated by controlling the energy device to output the target energy. During this process, the loop current between the energy device and the target tissue and its changing trend can be obtained in real time through current sensors.

[0033] S13: Predict whether the target tissue will be coagulated based on the change trend.

[0034] Specifically, after the maximum temperature of the target tissue exceeds 100°C, the loop current between the energy device and the target tissue will decrease rapidly. When the target tissue is burned, scabbed or charred, the loop current will be close to zero. Therefore, by obtaining the changing trend of the loop current, when the loop current does not show a trend of rapid decrease, it can be predicted in advance that the target tissue is about to coagulate, and the maximum temperature of the target tissue can be effectively controlled within the range of 100°C, thereby avoiding thermal damage such as burns, scabbing or charring to the target tissue.

[0035] S15: When it is predicted that the target tissue will be coagulated, the energy device is controlled to stop outputting the target energy.

[0036] Specifically, Figure 2 The relationship between the output power of the energy device and the loop impedance between the energy device and the target tissue is shown in the graph. Figure 1 As shown in the figure, the horizontal axis represents the loop impedance (R / Ω) between the energy device and the target tissue, and the vertical axis represents the output power (P / W) of the energy device. It can be seen from the figure that the output power gradually increases with the increase of the loop impedance, then remains stable within a certain loop impedance range, and then decreases with the increase of the loop impedance. When the loop impedance increases to R0 (such as 2000) Ω, the output power of the energy device will drop to a lower value P0 (such as 5W) to avoid burns, scabs or charring of the tissue during the operation. However, in the process of controlling the energy device according to the relationship curve, when the loop impedance increases to R0, the target tissue may have been burned, scabbed or charred. If the output power of the energy device is reduced at this time, it will be difficult to avoid burns, scabs or charring of the tissue.

[0037] Based on this, in an embodiment of the present invention, in the process of coagulating the target tissue, the loop current between the energy device and the target tissue is obtained in real time, and whether the target tissue is coagulated is predicted based on the change trend of the loop current. Then, when the target tissue is coagulated, the energy device is controlled to stop outputting the target energy, thereby reducing the thermal damage to the patient, ensuring the safety of the patient as much as possible, and improving the surgical effect. It can be understood that when the target tissue is coagulated, if the energy device is continued to be controlled to output the target energy, the target tissue will be burned, scabbed or charred. Therefore, when predicting whether the target tissue is coagulated based on the change trend of the loop current, the target tissue will also be predicted to be burned, scabbed or charred.

[0038] For example, Figure 3 A graph showing the relationship between loop current and target tissue temperature is shown in FIG. Figure 3As shown in the figure, the horizontal axis represents the maximum temperature of the target tissue (°C), and the vertical axis represents the loop current (A). In the process of controlling the energy device to coagulate the target tissue, the temperature of the target tissue will gradually rise with the passage of time. At this time, the conductivity of the target tissue will gradually increase with the increase in temperature. Since the conductivity is proportional to the loop current, the loop current between the energy device and the target tissue will also increase with the increase in conductivity. When the loop current reaches the maximum value Imax, the maximum temperature T1 of the target tissue will be close to 100°C. If a large amount of energy continues to be output at this time, the maximum temperature T1 of the target tissue will exceed 100°C, the moisture content of the target tissue will decrease rapidly, and the conductivity of the target tissue lacking moisture will also decrease rapidly, causing the change trend of the loop current to show a rapid downward trend. When the target tissue is burned, scabbed or charred, the conductivity of the target tissue will be close to zero, and the loop current will also drop to close to zero. Therefore, when the loop current just begins to show a downward trend, it is predicted that the target tissue will coagulate. At this time, the energy device is controlled in advance to stop outputting the target energy, thereby reducing the patient's thermal injury, ensuring the patient's safety as much as possible, and improving the surgical effect.

[0039] In the above embodiment, in the process of controlling the energy device to output the target energy to coagulate the target tissue, the loop current between the energy device and the target tissue and its changing trend are obtained, and when it is predicted that the target tissue will be coagulated according to the changing trend of the loop current, the energy device is controlled to stop outputting the target energy to avoid burns, scabbing or charring of the target tissue, thereby reducing the risk of thermal damage to the patient, ensuring the patient's safety as much as possible, and improving the surgical effect.

[0040] In some embodiments, based on the changing trend, the energy device is controlled to stop outputting the target energy, including: when the loop currents obtained for multiple consecutive times are all smaller than the corresponding previous loop currents, and after a preset delay time, it is predicted that the target tissue will be coagulated.

[0041] Exemplarily, the preset time has a value range of 8 ms to 15 ms, and the time interval between two adjacent loop currents acquired in the loop currents acquired multiple times in succession is less than or equal to 50 μs.

[0042] When predicting the coagulation of the target tissue, it is possible to first determine whether the loop current is in a downward trend. If so, after a delay of a period of time, it is predicted that the target tissue is about to coagulate, and the energy device is controlled to stop outputting the target energy. In other words, when it is determined that the loop current is actually showing a downward trend, it is predicted that the target tissue is about to coagulate, and the energy device is controlled to stop outputting the target energy in a short period of time to avoid thermal damage to the tissue caused by continued energy output. For example, assuming that the loop current between the energy device and the target tissue is obtained three times in a row as I1, I2, and I3, if I3 < I2 < I1, then after a preset delay of 10ms, it is predicted that the target tissue is about to coagulate, and the energy device is controlled to stop outputting the target energy.

[0043] In some embodiments, based on the changing trend, the energy device is controlled to stop outputting the target energy, including: when the loop currents acquired for multiple consecutive times are all smaller than their corresponding previous loop currents, and the deviation between the last acquired loop current and its corresponding previous loop current is greater than a preset deviation, it is predicted that the target tissue is about to coagulate.

[0044] Exemplarily, the deviation amount may be the current difference between the last loop current obtained and its corresponding previous loop current, or may be the ratio of the current difference between the last loop current obtained and its corresponding previous loop current to the loop current obtained last time, wherein, when the deviation amount is the current difference, the preset deviation amount is greater than or equal to 0.05A; when the deviation amount is the ratio of the current difference to the last loop current obtained, the preset deviation amount is greater than or equal to 5%.

[0045] When predicting the coagulation of the target tissue, it is possible to first determine whether the loop current is in a downward trend. If so, it is further determined whether it is showing a rapid downward trend. If so, it is predicted that the target tissue is about to coagulate. In other words, when it is determined that the loop current is actually showing a rapid downward trend, it can be predicted that the target tissue is about to coagulate. At this time, the energy device is controlled to stop outputting the target energy to avoid continued energy output that may cause thermal damage to the tissue.

[0046] Exemplarily, it is assumed that the loop currents between the energy device and the target tissue are obtained three times in succession as I1, I2 and I3.

[0047] As an example, if I3<I2<I1, and the current difference between I3 and I2 is greater than the preset current difference (such as 0.05A or above) or the ratio of the current difference between I3 and I2 in I2 is greater than the preset ratio (such as 5% or above), it is predicted that the target tissue is about to coagulate, and the energy device is directly controlled to stop outputting the target energy.

[0048] In some embodiments, based on the changing trend, the energy device is controlled to stop outputting the target energy, including: when the loop currents obtained for multiple consecutive times are all smaller than their corresponding previous loop currents, after a preset delay time or the deviation between the last loop current obtained and its corresponding previous loop current is greater than a preset deviation, it is predicted that the target tissue will be coagulated.

[0049] When predicting the coagulation of the target tissue, it is possible to first determine whether the loop current is in a downward trend. If so, it is further determined whether it is showing a rapid downward trend. At the same time, the time is determined so that when the loop current shows a rapid downward trend or the delay time reaches the preset delay time, it is predicted that the target tissue is about to coagulate. At this time, the energy device is controlled to stop outputting the target energy, thereby reducing the possibility of thermal damage to the tissue due to the inability to accurately judge whether the loop current is showing a rapid downward trend and the inability to stop the target energy output in time due to interference with the loop current, further reducing the possibility of tissue burns caused by excessive heating.

[0050] Exemplarily, it is assumed that the loop currents between the energy device and the target tissue are obtained three times in succession as I1, I2 and I3.

[0051] As another example, if I3<I2<I1, then after a preset delay of 10ms, or when the current difference between I3 and I2 is greater than a preset current difference (such as 0.05A or above) or the ratio of the current difference between I3 and I2 in I2 is greater than a preset ratio (such as 5% or above), it is predicted that the target tissue is about to coagulate, and the energy device is directly controlled to stop outputting the target energy.

[0052] In this way, by acquiring the loop current between the energy device and the target tissue multiple times in succession, the changing trend of the loop current can be accurately determined, thereby reducing the problem of inaccurate loop current acquisition due to signal interference or human factors, which in turn leads to inaccurate judgment of the changing trend of the loop current. This ensures that the loop current actually changes from an increasing trend to a decreasing trend, thereby achieving accurate control of the energy device, controlling the maximum temperature of the target tissue within a safe range as much as possible, and effectively avoiding thermal damage to the target tissue such as burns, scabs or scorching.

[0053] In the above embodiment, in the process of controlling the energy device to output the target energy to coagulate the target tissue, the loop current between the energy device and the target tissue and its changing trend are obtained, and according to the changing trend of the loop current, it is determined when to control the energy device to stop outputting the target energy, thereby avoiding the risk of thermal damage such as burns, scabbing or scorching of the target tissue caused by different judgment standards and limited field of view of medical staff, thereby improving the safety of the patient's surgery.

[0054] It should be noted that the specific numerical values ​​mentioned above are only used as examples to illustrate the implementation of the present invention in detail, and should not be understood as limiting the present invention. In other examples or implementations or embodiments, other numerical values ​​can be selected according to the present invention, and are not specifically limited here.

[0055] Corresponding to the above embodiments, an embodiment of the present invention further proposes a computer-readable storage medium on which a program is stored. When the program is executed by a processor, the energy device control method for tissue coagulation of any of the above embodiments is implemented.

[0056] According to the computer-readable storage medium of the embodiment of the present invention, when it is predicted that coagulation of the target tissue occurs according to the changing trend of the loop current, the energy device can be controlled to stop outputting the target energy to avoid burns, scabbing or charring of the target tissue, thereby reducing the thermal damage to the patient, ensuring the patient's safety as much as possible, and improving the surgical effect.

[0057] For example, when the program is executed by a processor, the following energy device control method for tissue coagulation is implemented:

[0058] S11: in the process of controlling the energy device to output target energy to coagulate the target tissue, obtaining a loop current between the energy device and the target tissue, and obtaining a change trend of the loop current;

[0059] S13: predict whether the target tissue will be coagulated based on the change trend;

[0060] S15: When it is predicted that the target tissue will be coagulated, the energy device is controlled to stop outputting the target energy.

[0061] It should be noted that the above-mentioned explanation of the embodiments and beneficial effects of the energy device control method for tissue coagulation is also applicable to the computer-readable storage medium of the embodiment of the present invention, and will not be elaborated here in detail to avoid redundancy.

[0062] Corresponding to the above embodiment, an embodiment of the present invention further proposes an energy device.

[0063] Figure 4 is a block diagram of an energy device according to an embodiment of the present invention. Figure 4 As shown, the energy device 100 includes a memory 102, a processor 104, and a program 106 stored in the memory 102 and executable on the processor 104. When the processor 104 executes the program 106, the energy device control method for tissue coagulation according to any of the above embodiments is implemented.

[0064] The energy device according to the embodiment of the present invention can predict the occurrence of coagulation of the target tissue based on the changing trend of the loop current, and control the energy device to stop outputting the target energy to avoid burns, scabbing or charring of the target tissue, thereby reducing thermal damage to the patient, ensuring the patient's safety as much as possible, and improving the surgical effect.

[0065] For example, when the program 106 is executed by the processor 104, the following energy device control method for tissue coagulation is implemented:

[0066] S11: in the process of controlling the energy device to output target energy to coagulate the target tissue, obtaining a loop current between the energy device and the target tissue, and obtaining a change trend of the loop current;

[0067] S13: predict whether the target tissue will be coagulated based on the change trend;

[0068] S15: When it is predicted that the target tissue will be coagulated, the energy device is controlled to stop outputting the target energy.

[0069] It should be noted that the above-mentioned explanation of the embodiment and beneficial effects of the energy device control method for tissue coagulation is also applicable to the energy device 100 of the embodiment of the present invention, and will not be elaborated here in detail to avoid redundancy.

[0070] Corresponding to the above-mentioned embodiment, an embodiment of the present invention further proposes an energy device control apparatus for tissue coagulation.

[0071] Figure 5 FIG. 1 is a block diagram of an energy device control apparatus for tissue coagulation according to an embodiment of the present invention. Figure 5 As shown, the energy device control apparatus 300 for tissue coagulation includes: an acquisition module 302 and a control module 304. The acquisition module 302 is used to acquire the loop current between the energy device and the target tissue and acquire the change trend of the loop current during the process of controlling the energy device to output the target energy to coagulate the target tissue; the control module 304 is used to predict whether the target tissue will coagulate based on the change trend, and control the energy device to stop outputting the target energy when it is predicted that the target tissue will coagulate.

[0072] According to the energy device control device for tissue coagulation of the embodiment of the present invention, the acquisition module obtains the loop current and its change trend between the energy device and the target tissue in the process of controlling the energy device to output the target energy to coagulate the target tissue, and the control module predicts whether the target tissue will coagulate based on the change trend, and controls the energy device to stop outputting the target energy when it is predicted that the target tissue will coagulate. Therefore, when it is predicted that the target tissue will coagulate according to the change trend of the loop current, the energy device can be controlled to stop outputting the target energy, avoiding the phenomenon of burns, scabs or charring on the target tissue, thereby reducing the situation of thermal damage to the patient, ensuring the safety of the patient as much as possible, and improving the surgical effect.

[0073] In some embodiments of the present invention, the control module 304 is specifically used to: when the loop currents obtained for multiple consecutive times are all smaller than the corresponding previous loop currents, and after a preset delay time, predict that the target tissue has coagulated.

[0074] In some embodiments of the present invention, the control module 304 is specifically used to predict that coagulation of the target tissue occurs when the loop currents acquired for multiple consecutive times are all smaller than their corresponding previous loop currents, and the deviation between the loop current acquired for the last time and its corresponding previous loop current is greater than a preset deviation.

[0075] In some embodiments of the present invention, the control module 304 is specifically used to: when the loop currents obtained for multiple consecutive times are all smaller than their corresponding previous loop currents, after a preset delay time or when the deviation between the last loop current obtained and its corresponding previous loop current is greater than a preset deviation, it is predicted that coagulation of the target tissue occurs.

[0076] In some embodiments of the present invention, the preset time ranges from 8 ms to 15 ms.

[0077] In some embodiments of the present invention, when the deviation is the current difference, the preset deviation is greater than or equal to 0.05A; when the deviation is the ratio of the current difference to the last acquired loop current, the preset deviation is greater than or equal to 5%.

[0078] In some embodiments of the present invention, the time interval between two adjacent acquisitions of the loop current is less than or equal to 50 μs.

[0079] It should be noted that the above explanation of the embodiment and beneficial effects of the energy device control method for tissue coagulation is also applicable to the energy device control apparatus 300 for tissue coagulation according to the embodiment of the present invention, and will not be elaborated here in detail to avoid redundancy.
