Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and in particular to an ablation device and a readable storage medium. Background Technology
[0002] Hypertension is a common chronic disease. If it is not detected and treated early, it will increase the mortality rate from cardiovascular events, stroke, and kidney disease. According to the 2020 International Hypertension Practice Guidelines and World Health Organization documents, hypertension is defined as a systolic blood pressure ≥140 mmHg and / or a diastolic blood pressure ≥90 mmHg after repeated measurements. The higher the blood pressure, the more difficult it is for the heart to pump blood. If left uncontrolled, hypertension can lead to: 1) heart attacks, enlarged hearts, and eventually heart failure; 2) blood vessels may bulge (forming aneurysms) and develop weak points due to the high pressure, making them more prone to blockage and rupture; 3) blood leaking into the brain, leading to stroke; 4) hypertension can also cause kidney failure, blindness, and cognitive impairment.
[0003] Hypertension is one of the most significant risk factors for cardiovascular and cerebrovascular diseases. Although lifestyle modifications and medication are effective ways to lower blood pressure, the control rate of hypertension remains low. Blood pressure is controlled by a complex interaction of signals from multiple systems in the body (nervous system, circulatory system, and endocrine system, etc.), and the kidneys play a central role in long-term blood pressure regulation. Abnormalities in the renal sympathetic nervous system can cause blood pressure to rise through both afferent and efferent nerve mechanisms. Renal sympathetic denervation (RDN) can significantly reduce renal sympathetic nerve activity, preventing the maintenance and progression of hypertension.
[0004] Renal sympathetic denervation (RDN) lowers blood pressure by inhibiting the activity of the renal sympathetic nerves. Radiofrequency ablation is one of the most common nerve ablation methods. RDN involves percutaneous insertion of a radiofrequency ablation catheter through the femoral artery to both renal arteries. Electrodes on the catheter release radiofrequency energy in selected areas, generating high temperatures in the renal artery intima. This selectively blocks the conduction function of sympathetic nerve fibers in the renal artery wall, reducing sympathetic nerve excitability and thus lowering blood pressure. Ablation of afferent nerves reduces nerve impulses to the ascending central nervous system, decreasing sympathetic nerve excitability, thereby lowering heart rate, myocardial contractility, and stroke volume, thus reducing cardiac output and lowering blood pressure. Ablation of efferent nerves reduces descending nerve activity, increasing glomerular filtration rate, decreasing renal reabsorption capacity, and reducing sodium and water reabsorption. This leads to increased sodium and water excretion, reducing blood volume and lowering blood pressure.
[0005] Currently available renal artery ablation devices lack an immediate and effective feedback mechanism for doctors after the procedure. This situation leaves surgeons without a clear and reliable indicator to confirm whether the surgery achieved the desired results. Due to the lack of immediate assessment methods, doctors often struggle to accurately determine whether renal artery ablation has completely eliminated sympathetic nerve innervation in the target area.
[0006] To compensate for this deficiency, some surgeons have proposed using CT scans immediately after surgery to observe whether blood vessels have dilated, thus indirectly determining whether the sympathetic nervous system has lost its innervation. However, while this method may provide doctors with an observation tool to some extent, it inevitably increases the radiation exposure burden on patients. Postoperative patients are already in a relatively weak state, and additional radiation exposure will undoubtedly have an adverse effect on their postoperative recovery and may even increase potential health risks.
[0007] Furthermore, the accuracy of measuring the degree of vascular dilation using CT images is relatively low. Due to limitations such as spatial resolution and contrast in CT images, doctors may encounter difficulties in interpreting the images and accurately determining the true state of the blood vessels. This not only increases diagnostic uncertainty but may also mislead doctors' judgment of surgical outcomes, thereby affecting subsequent treatment decisions and the patient's recovery process.

[0037] Compared with the prior art, the ablation device and readable storage medium provided by the present invention have the following beneficial effects:
[0038] During ablation surgery, when the sympathetic nerve is effectively ablated, a significant decrease in peripheral resistance occurs in the blood vessels it innervates, manifested as a marked change in the dicrotic wave. Therefore, the ablation device provided by this invention uses an energy generation module to provide ablation energy to the medical catheter for ablation of the target blood vessel. It uses a blood pressure detection module to collect first blood pressure data within a first preset time window before the procedure and second blood pressure data within a second preset time window after each ablation. It obtains preoperative dicrotic wave amplitude information based on the first blood pressure data and, after each ablation, obtains post-ablation dicrotic wave amplitude information based on the second blood pressure data. Thus, for each ablation, the device can provide timely feedback on the surgical effect based on the preoperative dicrotic wave amplitude information and the post-ablation dicrotic wave amplitude information, thereby helping the surgeon determine whether the sympathetic nerve has lost its innervation. In summary, the ablation device provided by this invention not only facilitates the surgeon's immediate assessment of the ablation effect (denervation effect) during the procedure, effectively reducing the learning curve, improving surgical response rate and safety, but also effectively shortens the surgical radiation exposure time, reducing patient discomfort. Furthermore, since the damage to the sympathetic nerves caused by ablation and the effect on vasodilation after the loss of sympathetic nerve innervation are cumulative processes, the ablation device provided by this invention determines whether further ablation of the target vessel is necessary after each ablation based on the post-ablation dichroic wave amplitude information and the pre-operative dichroic wave amplitude information, thereby effectively ensuring the accuracy of the judgment results.

Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
[0054] The core idea of this invention is to provide an ablation device and a readable storage medium, which not only allows the surgeon to easily judge the immediate ablation effect (denervation effect) during the procedure, effectively reducing the learning curve of the procedure, improving the surgical response rate and safety, but also effectively shortens the surgical radiation exposure time and reduces patient suffering.
[0055] It should be noted that the readable storage medium provided by this invention can be applied to the ablation device provided by this invention. Furthermore, it should be noted that although this invention uses the renal artery as the target vessel in the description, as those skilled in the art will understand, this does not constitute a limitation of the invention; the target vessel can also be the aorta or other vessels.
[0056] To achieve the above-mentioned goals, this invention provides an ablation device, please refer to [reference needed]. Figure 1 This is a schematic diagram of the block structure of an ablation device provided in one embodiment of the present invention. Figure 1 As shown, the ablation device provided by the present invention includes a controller 100, an energy generation module 200, a blood pressure detection module 300, and a medical catheter 400. Both the energy generation module 200 and the blood pressure detection module 300 are communicatively connected to the controller 100, and the medical catheter 400 is electrically connected to the energy generation module 200. The energy generation module 200 is configured to provide ablation energy to the medical catheter 400 under the control of the controller 100 to ablate the target blood vessel. The blood pressure detection module 300 is configured to collect a first blood sample within a first preset time window before the procedure. Within a second preset time window after each ablation, second blood pressure data is collected, and the first blood pressure data and the second blood pressure data are transmitted to the controller 100. The controller 100 is configured to: obtain preoperative dicrotic wave amplitude information based on the first blood pressure data; after each ablation, obtain post-ablation dicrotic wave amplitude information corresponding to the ablation based on the second blood pressure data after the ablation, and determine whether it is necessary to continue ablation on the target vessel after the ablation based on the preoperative dicrotic wave amplitude information and the post-ablation dicrotic wave amplitude information corresponding to the ablation.
[0057] During ablation surgery, when the sympathetic nerve is effectively ablated, a significant decrease in peripheral resistance occurs in the blood vessels it innervates, manifested as a significant change in the dicrotic wave. Therefore, the ablation device provided by this invention uses an energy generation module 200 to provide ablation energy to the medical catheter 400 to ablate the target blood vessel. A blood pressure detection module 300 collects first blood pressure data within a first preset time window before the procedure and second blood pressure data within a second preset time window after each ablation. Preoperative dicrotic wave amplitude information is obtained based on the first blood pressure data. After each ablation, the post-ablation dicrotic wave amplitude information is obtained based on the second blood pressure data. Thus, for each ablation, the surgical effect can be promptly reported based on the preoperative dicrotic wave amplitude information and the post-ablation dicrotic wave amplitude information, thereby helping the surgeon determine whether the sympathetic nerve has lost its innervation. In summary, the ablation device provided by this invention not only facilitates the surgeon's immediate assessment of the ablation effect (denervation effect) during the procedure, effectively reducing the learning curve, improving surgical response rate and safety, but also effectively shortens surgical radiation exposure time, reducing patient discomfort. Furthermore, since the damage to the sympathetic nerves caused by ablation and the effect on vasodilation after the loss of sympathetic nerve innervation are cumulative processes, the immediate ablation effect (denervation effect) can be accurately reflected after each ablation based on the post-ablation dichroic wave amplitude information and the pre-operative dichroic wave amplitude information. Moreover, since the damage to the sympathetic nerves caused by ablation and the effect on vasodilation after the loss of sympathetic nerve innervation are cumulative processes, the ablation device provided by this invention, by determining whether further ablation of the target vessel is necessary after each ablation based on the post-ablation dichroic wave amplitude information and the pre-operative dichroic wave amplitude information, effectively ensures the accuracy of the judgment results. In addition, the ablation device provided by the present invention is an integrated device that combines an energy generation module 200 and a blood pressure detection module 300. It can integrate the functions that originally required multiple independent products to work together, avoid the incompatibility problems that may occur when multiple products are connected to each other, and also greatly reduce the messy cable situation in the operating room.
[0058] Specifically, the energy generation module 200 is responsible for precisely controlling the output of ablation energy, ensuring the accuracy and safety of the surgical procedure, while the blood pressure monitoring module 300 is responsible for real-time monitoring of the patient's blood pressure changes, providing the surgeon with crucial vital sign information. The energy generation module 200 and the blood pressure monitoring module 300 are seamlessly integrated on the device, operated and controlled through a unified user interface, greatly reducing the complexity of clinical procedures. This not only improves surgical efficiency but also reduces the workload of medical staff, providing patients with a safer and more efficient surgical treatment experience.
[0059] Furthermore, the ablation energy provided by the energy generation module 200 can be, but is not limited to, radiofrequency energy, pulse energy, and ultrasound energy. Furthermore, the controller 100 can control the energy generation module 200 to provide ablation energy to the medical catheter 400 based on user-set ablation parameter ranges to ablate the target blood vessel. Ablation parameters include ablation power, ablation time, and temperature control. Specifically, the adjustable range of ablation power is 1W to 30W, preferably 6W to 15W; the adjustable range of ablation time is 1s to 180s, preferably 60s to 90s; and the temperature control range is 40℃ to 50℃, preferably 40℃ to 45℃. Furthermore, the ablation parameter range can be selected and input by the operator via a keyboard or other operating unit on the display interface provided by the display module 500 (described below). The preferred default parameter for ablation power is 8W, and the preferred default parameter for ablation time is 90s. The surgical operator can adjust the ablation power and ablation time according to the patient's blood vessel diameter and the position of the ablation electrode on the medical catheter 400. Furthermore, the blood pressure detection range of the blood pressure detection module 300 is 0mmHg to 300mmHg, preferably 50mmHg to 250mmHg.
[0060] Furthermore, the blood pressure detection module 300 can be an invasive blood pressure detection device, thereby enabling the controller 100 to accurately obtain preoperative dicrotic wave amplitude information based on the first blood pressure data collected by the blood pressure detection module 300 (invasive blood pressure detection device), and to accurately obtain post-ablation dicrotic wave amplitude information based on the second blood pressure data collected by the blood pressure detection module 300 (invasive blood pressure detection device).
[0061] It should be noted that the dicrotic wave is the waveform corresponding to the second heart sound generated by the elastic recoil of the aortic root at the end of cardiac systole. Its changes are closely related to peripheral vascular resistance. Therefore, by performing in-depth analysis of the dicrotic wave, the dynamic changes in peripheral vascular resistance before and after ablation can be accurately determined.
[0062] It should also be noted that on a pulse waveform (blood pressure waveform), the dicrotic wave is usually located after the main wave (i.e., the systolic peak) and is a smaller peak. It appears on the descending limb of the pulse wave and the waveform shows an upward trend. The dicrotic wave peak is the highest point of the dicrotic wave waveform; the height of the dicrotic wave is usually lower than the main wave but higher than other reflected waves or tidal waves. By comparing the height and position of different waveforms, the dicrotic wave can be more easily identified. Furthermore, it should be noted that the dicrotic wave amplitude refers to the height between the dicrotic wave peak and a baseline parallel to the bottom of the descending trough.
[0063] Furthermore, the present invention does not limit the specific values of the first preset time window and the second preset time window. The specific values of the first preset time window and the second preset time window can be set according to actual needs. The value range of the first preset time window and the second preset time window can be set to 1s to 60s. For example, the first preset time window and the second preset time window can both be set to 10s. It should be noted that, as those skilled in the art will understand, the values of the first preset time window and the second preset time window can be the same or different.
[0064] In some exemplary embodiments, the controller 100 is configured to obtain the preoperative dicrotic wave amplitude information based on the average amplitude of each dicrotic wave in the first blood pressure data.
[0065] Therefore, by obtaining the preoperative dicrotic wave amplitude information based on the average value of all dicrotic waves in the first blood pressure data collected before the operation, the present invention can effectively ensure the accuracy and stability of the obtained preoperative dicrotic wave amplitude information, thus laying a good foundation for accurately reflecting the surgical effect of each ablation.
[0066] In some exemplary embodiments, the controller 100 is configured to: after each ablation, obtain the post-ablation dichroic wave amplitude information corresponding to the ablation based on the average amplitude of each dichroic wave in the second blood pressure data after the ablation.
[0067] Therefore, after each ablation, the amplitude information of the post-ablation dichroic wave is obtained by averaging all dichroic waves in the second blood pressure data collected after the ablation. This can effectively ensure the accuracy of the obtained post-ablation dichroic wave amplitude information, thus laying a good foundation for accurately reflecting the surgical effect of each ablation.
[0068] In some exemplary embodiments, the controller 100 is configured to: after each ablation, obtain the change information of the dichroic wave amplitude corresponding to the ablation based on the preoperative dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to the ablation, and determine whether it is necessary to continue ablation on the target vessel after the ablation based on the change information of the dichroic wave amplitude corresponding to the ablation.
[0069] Therefore, after each ablation, by using the preoperative dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to that ablation, the change information of the dichroic wave amplitude corresponding to that ablation can be obtained. This allows for accurate feedback of the ablation effect based on the change information of the dichroic wave amplitude corresponding to that ablation, thus laying a good foundation for accurately determining whether further ablation of the target vessel is necessary.
[0070] In some exemplary embodiments, the diphtheria wave amplitude change information includes either information on the amount of decrease in diphtheria wave amplitude or information on the percentage decrease in diphtheria wave amplitude.
[0071] During ablation surgery, when the sympathetic nerve is effectively ablated, there will be a significant decrease in peripheral resistance in the blood vessel area it innervates, which is manifested as a significant reduction in the amplitude of the dichroic wave. Therefore, after each ablation, the ablation effect can be accurately reflected based on the amount or percentage of the decrease in the amplitude of the dichroic wave corresponding to that ablation.
[0072] Please continue to refer to this. Figure 2 and Figure 3 ,in, Figure 2 A preoperative blood pressure waveform diagram provided as a specific example of the present invention; Figure 3 This is a postoperative blood pressure waveform provided as a specific example of the present invention. By comparison... Figure 2 and Figure 3 It can be seen that the amplitude of the dichroic wave after surgery was significantly reduced compared to the amplitude of the dichroic wave before surgery.
[0073] Specifically, for each ablation, the decrease in dichroic wave amplitude corresponding to that ablation is equal to the difference between the preoperative average dichroic wave amplitude and the postoperative average dichroic wave amplitude corresponding to that ablation; the percentage decrease in dichroic wave amplitude corresponding to that ablation is equal to the percentage of the difference between the preoperative average dichroic wave amplitude and the postoperative average dichroic wave amplitude corresponding to that ablation, and the preoperative average dichroic wave amplitude.
[0074] It should be noted that, in some other implementations, after each ablation, the change information of the dichroic wave amplitude corresponding to that ablation can be obtained based on the ratio of the average dichroic wave amplitude after the ablation to the average dichroic wave amplitude before the procedure.
[0075] Please continue to refer to this. Figure 4 This is a flowchart illustrating the immediate ablation effect judgment of the ablation device provided in one embodiment of the present invention. Figure 4 As shown, in some exemplary embodiments, the controller 100 is configured to: if the decrease in the dicrotic wave amplitude corresponding to the ablation is less than a first preset amplitude, or the percentage decrease in the dicrotic wave amplitude corresponding to the ablation is less than a first preset percentage, then determine that the target blood vessel needs to be ablated again after the ablation, and control the energy generation module 200 to increase the output power to continue ablation at the ablation site corresponding to the ablation, or prompt the surgeon to move the medical catheter 400 to the next ablation site to continue ablation.
[0076] Since the decrease in dicrotic wave amplitude corresponding to a certain ablation is less than the first preset amplitude (e.g., 2 mmHg), or the percentage decrease in dicrotic wave amplitude corresponding to that ablation is less than the first preset percentage (e.g., 10%), it indicates that the damage to the sympathetic nerve after that ablation is still insufficient, or that the sympathetic nerve is buried in a deeper location. Therefore, by determining under this condition that it is necessary to continue ablation on the target blood vessel after that ablation, and controlling the energy generation module 200 to increase the output power to continue ablation at the ablation site corresponding to that ablation, or prompting the surgeon to move the medical catheter 400 to the next ablation site to continue ablation, the ablation effect on the target blood vessel can be fully guaranteed.
[0077] It should be noted that although the present invention is illustrated using the first preset amplitude of 2 mmHg and the first preset percentage of 10% as an example, as those skilled in the art will understand, the present invention does not limit the specific values of the first preset amplitude and the first preset percentage, and the specific values of the first preset amplitude and the first preset percentage can be set according to actual circumstances.
[0078] Please continue to refer to this. Figure 4 ,like Figure 4 As shown, in some exemplary embodiments, the controller 100 is configured to: if the decrease in the dicrotic wave amplitude corresponding to the ablation is greater than or equal to a first preset amplitude and less than or equal to a second preset amplitude, or the percentage decrease in the dicrotic wave amplitude corresponding to the ablation is greater than or equal to a first preset percentage and less than or equal to a second preset percentage, then it is determined that the target vessel needs to be ablated again after the ablation, and the surgeon is prompted to move the medical catheter 400 to the next ablation site to continue ablation or to the vicinity of the ablation site corresponding to the ablation to continue ablation.
[0079] Since the decrease in dicrotic wave amplitude corresponding to a certain ablation is greater than or equal to the first preset amplitude (e.g., 2 mmHg) and less than or equal to the second preset amplitude (e.g., 4 mmHg), or the percentage decrease in dicrotic wave amplitude corresponding to the ablation is greater than or equal to the first preset percentage (e.g., 10%) and less than or equal to the second preset percentage (e.g., 20%), it indicates that the ablation of the sympathetic nerve is effective and the sympathetic nerve has been significantly damaged, but the damage to the sympathetic nerve is still insufficient. Therefore, by determining under this condition that it is necessary to continue ablation on the target blood vessel after the ablation, and prompting the surgeon to move the medical catheter 400 to the next ablation site to continue ablation or to the vicinity of the ablation site corresponding to the current ablation to continue ablation, the ablation effect on the target blood vessel can be fully guaranteed.
[0080] It should be noted that although this invention is described using a second preset amplitude of 4 mmHg and a second preset percentage of 20% as an example, as those skilled in the art will understand, this invention does not limit the specific values of the second preset amplitude and the second preset percentage, and these values can be set according to actual circumstances. It should also be noted that, as those skilled in the art will understand, the surgical operator can slightly adjust the position of the medical catheter 400 (i.e., the position of the electrode) to move the medical catheter 400 to a region near the ablation site corresponding to this ablation (e.g., a region no more than 5 mm from the original ablation site).
[0081] In some exemplary embodiments, the controller 100 is further configured to: if the decrease in dicrotic wave amplitude corresponding to the ablation is greater than or equal to a first preset amplitude and less than or equal to a second preset amplitude, or the percentage decrease in dicrotic wave amplitude corresponding to the ablation is greater than or equal to a first preset percentage and less than or equal to a second preset percentage, then control the energy generation module 200 to provide stimulation energy to the medical catheter 400 to stimulate the ablation site corresponding to the ablation; if the average dicrotic wave amplitude during the stimulation process is greater than the average dicrotic wave amplitude before stimulation, then prompt the surgical operator to move the medical catheter 400 to the vicinity of the ablation site corresponding to the ablation to continue the ablation.
[0082] When specific nerve regions are stimulated externally, a series of physiological responses are triggered, one of which is vasoconstriction. This vasoconstriction directly increases peripheral vascular resistance, thereby affecting the dynamic characteristics of blood circulation, especially the dicrotic wave component in the blood pressure waveform. The dicrotic wave, a key feature of the blood pressure waveform, reflects various physiological states of the vascular system through changes in its morphology and amplitude. Under normal circumstances, the dicrotic wave occurs due to the deceleration of blood after aortic valve closure and the reverse flow of blood at the aortic root during ventricular diastole. However, when nerve stimulation causes vasoconstriction, this reverse flow is impeded, thus altering the morphology and amplitude of the dicrotic wave. Therefore, this invention assists the surgeon in determining whether activated sympathetic nerves still exist in the vicinity of the ablation site when the decrease in dicrotic wave amplitude during a single ablation is greater than or equal to the first preset amplitude (e.g., 2 mmHg) and less than or equal to the second preset amplitude (e.g., 4 mmHg), or when the percentage decrease in dicrotic wave amplitude is greater than or equal to the first preset percentage (e.g., 10%) and less than or equal to the second preset percentage (e.g., 20%). Specifically, if the average dicrotic wave amplitude during stimulation is greater than the average dicrotic wave amplitude before stimulation, it indicates that activated sympathetic nerves still exist in the vicinity of the current stimulation site (i.e., the ablation site corresponding to this ablation). This prompts the surgeon to move the medical catheter 400 to the vicinity of the ablation site to continue ablation, effectively ensuring the ablation effect. If the average amplitude of the diphthong wave during stimulation is less than or equal to the average amplitude of the diphthong wave before stimulation, it indicates that there are no activated sympathetic nerves in the vicinity of the current stimulation site (i.e., the ablation site corresponding to this ablation). Therefore, by prompting the surgeon to move the medical catheter 400 to a new ablation site for ablation, the ablation effect can be effectively guaranteed.
[0083] It should be noted that, as those skilled in the art will understand, the surgical operator can fine-tune the position of the medical catheter 400 to move the medical catheter 400 to the vicinity of the ablation site corresponding to the ablation.
[0084] Please continue to refer to this. Figure 4 ,like Figure 4As shown, in some exemplary embodiments, the controller 100 is configured to: determine that no further ablation of the target vessel is required if the decrease in dicrotic wave amplitude corresponding to the ablation is greater than a second preset amplitude and the dicrotic wave fluctuation is stable within a preset time period after the ablation, or if the percentage decrease in dicrotic wave amplitude corresponding to the ablation is greater than a second preset percentage and the dicrotic wave fluctuation is stable within a preset time period after the ablation (e.g., the percentage increase in dicrotic wave amplitude is less than or equal to 10%); and / or if the decrease in dicrotic wave amplitude corresponding to the ablation is greater than a second preset amplitude and the dicrotic wave fluctuation is unstable within a preset time period after the ablation, or if the percentage decrease in dicrotic wave amplitude corresponding to the ablation is greater than a second preset percentage and the dicrotic wave fluctuation is unstable within a preset time period after the ablation (e.g., the percentage increase in dicrotic wave amplitude is greater than 10%), prompt the surgical operator to move the medical catheter to the next ablation site to continue ablation.
[0085] If the decrease in dichroic wave amplitude corresponding to a certain ablation is greater than the second preset amplitude (e.g., 4 mmHg) or the percentage decrease in dichroic wave amplitude is greater than the second preset percentage (e.g., 20%), and the dichroic wave fluctuation is stable (without significant rebound) within the preset time after the ablation, it indicates that the sympathetic nerve damage after the ablation is relatively obvious and the ablation effect is relatively stable. Therefore, the operation can be terminated, meaning that there is no need to continue ablation on the target vessel. If the decrease in dichroic wave amplitude corresponding to a certain ablation is greater than the second preset amplitude (e.g., 4 mmHg) or the percentage decrease in dichroic wave amplitude is greater than the second preset percentage (e.g., 20%), and the dichroic wave fluctuation is not stable (significant rebound) within the preset time after the ablation, then it is necessary to continue to find new ablation sites for ablation.
[0086] In some exemplary embodiments, the energy generating module 200 is also configured to provide stimulating energy to the medical catheter 400 under the control of the controller 100 to stimulate the target blood vessel.
[0087] The blood pressure detection module 300 is also configured to collect third blood pressure data within a third preset time window before each stimulation, and to collect fourth blood pressure data during each stimulation.
[0088] The controller 100 is further configured to: for each stimulus: obtain the average amplitude of the pre-stimulation dichroic wave corresponding to the stimulus based on the third blood pressure data before the stimulus; obtain the average amplitude of the stimulation dichroic wave corresponding to the stimulus based on the fourth blood pressure data during the stimulus; if the average amplitude of the stimulation dichroic wave corresponding to the stimulus is greater than the average amplitude of the pre-stimulation dichroic wave corresponding to the stimulus, then determine that the stimulation site corresponding to the stimulus is an ablation site where sympathetic nerves exist.
[0089] As the sympathetic nervous system is part of the autonomic nervous system, its activity significantly influences vascular tone, heart rate, and the function of various internal organs. When nerve stimulation causes vasoconstriction, this reverse flow is impeded, altering the morphology and amplitude of the dichroic wave. Therefore, this invention, by monitoring changes in the dichroic wave during stimulation, can not only determine the activation state of the sympathetic nervous system to confirm the presence of sympathetic nerves at the stimulation site, but also further analyze its mechanism of action under specific physiological or pathological conditions. Furthermore, by combining stimulation with the method of locating sympathetic nerve ablation sites, this invention can effectively improve the surgical response rate and avoid reducing the surgical success rate due to inaccurate sympathetic nerve ablation sites.
[0090] It should be noted that, as those skilled in the art will understand, the present invention does not limit the specific value of the third preset time window. The specific value of the third preset time window can be set according to the actual situation. The value range of the third preset time window can be 1s to 60s. For example, the third preset time window can be set to 10s.
[0091] Please continue to refer to this. Figure 1 ,like Figure 1 As shown, in some exemplary embodiments, the ablation device provided by the present invention further includes a display module 500 communicatively connected to the controller 100. The display module 500 is configured to display the preoperative dicrotic wave amplitude information and the post-ablation dicrotic wave amplitude information. Thus, by displaying the preoperative dicrotic wave amplitude information, the preoperative dicrotic wave amplitude information can be intuitively presented to the surgical operator; by displaying the post-ablation dicrotic wave amplitude information corresponding to each ablation, the post-ablation dicrotic wave amplitude information after each ablation can be intuitively presented to the surgical operator.
[0092] In some exemplary embodiments, the controller 100 is further configured to: acquire preoperative systolic blood pressure information, preoperative diastolic blood pressure information, preoperative pulse pressure information, and preoperative pulse information based on the first blood pressure data; and after each ablation, acquire post-ablation systolic blood pressure information, post-ablation diastolic blood pressure information, post-ablation pulse pressure information, and post-ablation pulse information based on the second blood pressure data after that ablation.
[0093] Specifically, preoperative systolic blood pressure information can be obtained based on the average value of each systolic blood pressure in the first blood pressure data; preoperative diastolic blood pressure information can be obtained based on the average value of each diastolic blood pressure in the first blood pressure data; preoperative pulse pressure difference information can be obtained based on the average value of each pulse pressure difference (the difference between systolic and diastolic blood pressure) calculated from the first blood pressure data; and preoperative pulse information can be obtained based on the average value of the pulse calculated from the first blood pressure data. After each ablation, post-ablation systolic blood pressure information corresponding to that ablation is obtained based on the average value of each systolic blood pressure in the second blood pressure data after that ablation; post-ablation diastolic blood pressure information corresponding to that ablation is obtained based on the average value of each diastolic blood pressure in the second blood pressure data after that ablation; post-ablation pulse pressure difference information corresponding to that ablation is obtained based on the average value of the pulse pressure difference calculated from the second blood pressure data after that ablation; and post-ablation pulse information corresponding to that ablation is obtained based on the average value of the pulse calculated from the second blood pressure data after that ablation.
[0094] In some exemplary embodiments, the blood pressure detection module 300 is further configured to: collect fifth blood pressure data within each fourth preset time window during each ablation process and transmit it to the controller 100; the controller 100 is further configured to, during each ablation process, acquire real-time systolic blood pressure information, real-time diastolic blood pressure information, real-time pulse pressure information, real-time pulse information, and real-time dicrotic wave amplitude information based on the fifth blood pressure data within each fourth preset time window during that ablation process, and acquire real-time dicrotic wave amplitude change information based on the preoperative dicrotic wave amplitude information and the real-time dicrotic wave amplitude information.
[0095] Specifically, for each fourth preset time window, the corresponding real-time systolic pressure information can be obtained based on the average value of each systolic pressure in the fifth blood pressure data collected within the fourth preset time window; the corresponding real-time diastolic pressure information can be obtained based on the average value of each diastolic pressure in the fifth blood pressure data collected within the fourth preset time window; the corresponding real-time pulse pressure information can be obtained based on the average value of the pulse pressure calculated from the fifth blood pressure data collected within the fourth preset time window; the corresponding real-time pulse information can be obtained based on the average value of the pulse calculated from the fifth blood pressure data collected within the fourth preset time window; and the corresponding real-time dicrotic wave amplitude information can be obtained based on the average value of each dicrotic wave amplitude in the fifth blood pressure data collected within the fourth preset time window.
[0096] It should be noted that, as those skilled in the art will understand, the present invention does not limit the specific value of the fourth preset time window. The specific value of the fourth preset time window can be set according to actual needs, and the range of the fourth preset time window can be set to 1s to 60s. For example, the fourth preset time window can be set to 10s. It should also be noted that, for each ablation, if the ablation time is 60s and the fourth preset time window is 10s, the ablation process of this ablation can be divided into 6 fourth preset time windows. That is, every fourth preset time window, the real-time systolic blood pressure information, real-time diastolic blood pressure information, real-time pulse pressure information, real-time pulse information, and real-time dicrotic wave amplitude information during this ablation process can be updated once.
[0097] In some exemplary embodiments, the display module 500 is configured to provide a surgical interface 510 to display the preoperative systolic blood pressure information, preoperative diastolic blood pressure information, preoperative pulse pressure information, preoperative pulse information, preoperative dicrotic wave amplitude information, real-time systolic blood pressure information, real-time diastolic blood pressure information, real-time pulse pressure information, real-time pulse information, and real-time dicrotic wave amplitude information during each ablation procedure. This allows the surgeon to more intuitively assess the real-time ablation effect.
[0098] Please continue to refer to this. Figure 5 This is a schematic diagram of the surgical interface 510 provided in one embodiment of the present invention. Figure 5 As shown, the surgical interface 510 includes a frozen window 511 and a real-time window 512. The frozen window 511 is configured to display the preoperative systolic blood pressure information, the preoperative diastolic blood pressure information, the preoperative pulse pressure information, the preoperative pulse information, and the preoperative dicrotic wave amplitude information. The real-time window 512 is configured to display the real-time systolic blood pressure information, the real-time diastolic blood pressure information, the real-time pulse pressure information, the real-time pulse information, and the real-time dicrotic wave amplitude information. Therefore, this display method makes it easier for the surgeon to distinguish between preoperative and intraoperative information.
[0099] In some exemplary embodiments, the blood pressure detection module 300 is further configured to collect the sixth blood pressure data within the fifth preset time window before each ablation and transmit it to the controller 100. The controller 100 is further configured to: before each ablation, based on the sixth blood pressure data before the ablation, obtain the pre-ablation systolic blood pressure information, pre-ablation diastolic blood pressure information, pre-ablation pulse pressure information, pre-ablation pulse information, and pre-ablation dichroic wave amplitude information corresponding to the ablation; and after each ablation, based on the pre-ablation dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to the ablation, obtain the single ablation dichroic wave amplitude decrease information corresponding to the ablation.
[0100] Specifically, before each ablation, the pre-ablation systolic blood pressure information can be obtained based on the average of each systolic blood pressure in the sixth blood pressure data set before the ablation; the pre-ablation diastolic blood pressure information can be obtained based on the average of each diastolic blood pressure in the sixth blood pressure data set before the ablation; the pre-ablation pulse pressure information can be obtained based on the average of the pulse pressure calculated from the sixth blood pressure data set before the ablation; and the pre-ablation pulse information can be obtained based on the average of the pulse calculated from the sixth blood pressure data set before the ablation. After each ablation, the percentage decrease in dichroic wave amplitude corresponding to the single ablation can be obtained based on the difference between the pre-ablation and post-ablation dichroic wave amplitude and the pre-ablation dichroic wave amplitude.
[0101] In some exemplary embodiments, the display module 500 is further configured to provide an ablation review interface 520, which displays, after each ablation, the pre-ablation systolic blood pressure, pre-ablation pulse pressure, pre-ablation pulse rate, pre-ablation dichroic wave amplitude, post-ablation systolic blood pressure, post-ablation diastolic blood pressure, post-ablation pulse pressure, post-ablation pulse rate, post-ablation dichroic wave amplitude, and single-ablation dichroic wave amplitude decrease information. This allows the surgeon to more easily and intuitively compare the ablation effect of the current ablation with the previous ablation.
[0102] Please continue to refer to this. Figure 6 This is a schematic diagram of the ablation review interface 520 provided in one embodiment of the present invention. Figure 6As shown, the ablation review interface 520 includes a pre-ablation window 521 and a post-ablation window 522. The pre-ablation window 521 is configured to display the pre-ablation systolic blood pressure, pre-ablation diastolic blood pressure, pre-ablation pulse pressure, pre-ablation pulse rate, and pre-ablation dichroic wave amplitude information corresponding to each ablation. The post-ablation window 522 is configured to display the post-ablation systolic blood pressure, post-ablation diastolic blood pressure, post-ablation pulse pressure, post-ablation pulse rate, post-ablation dichroic wave amplitude information, and single-ablation dichroic wave amplitude decrease information corresponding to each ablation.
[0103] In some exemplary embodiments, the display module 500 is further configured to provide a stimulation review interface 530 to display the third blood pressure data, fourth blood pressure data, percentage increase in dicrotic wave amplitude, maximum systolic blood pressure, maximum diastolic blood pressure, and stimulation parameters corresponding to each stimulation. This allows the surgeon to visually observe the degree of influence of the stimulation on the vascular system, thereby enabling the surgeon to gain a deeper understanding of the role of the sympathetic nervous system.
[0104] Specifically, for each stimulus, the percentage increase in dichroic wave amplitude corresponding to the stimulus can be calculated based on the difference between the average dichroic wave amplitude corresponding to the stimulus and the average dichroic wave amplitude before the stimulus, and the percentage of the average dichroic wave amplitude before the stimulus.
[0105] Please continue to refer to this. Figure 7 This is a schematic diagram of a stimulus recall interface 530 provided in one embodiment of the present invention. Figure 7 As shown in the figure, Dicrotic% represents the percentage increase in dicrotic wave amplitude; IBP represents invasive blood pressure; PR represents pulse; Current represents stimulation current; Pulse represents pulse width; and Freq. represents stimulation frequency.
[0106] The overall workflow of the ablation device provided by this invention will be described below using the renal artery as an example of the target blood vessel. Please refer to... Figure 8 This is a flowchart illustrating the overall workflow of the ablation device provided in one embodiment of the present invention. Figure 8As shown, after the doctor connects and starts the blood pressure monitoring module 300 (e.g., an invasive blood pressure sensor) to the patient, the device begins to collect blood pressure data in real time and calculates data such as systolic blood pressure, diastolic blood pressure, pulse pressure, pulse, and dicrotic wave amplitude. After a time window (used to calculate the average value, which can be set from 1 to 60 seconds, here it is 10 seconds), the doctor will obtain data such as the preoperative average systolic blood pressure, preoperative average diastolic blood pressure, preoperative average pulse pressure, preoperative average pulse, and preoperative average dicrotic wave amplitude on the interface, and can observe the current real-time data such as systolic blood pressure, diastolic blood pressure, pulse pressure, pulse, and dicrotic wave amplitude in the real-time window 512. When the catheter reaches the first position, the default parameters are selected as stimulation frequency 10Hz, stimulation current 20mA, stimulation pulse width 2ms, and stimulation time 60s to start stimulation. During the stimulation process, the blood pressure curve changes are observed in real time, and the device will automatically pop up the stimulation review interface 530 after stimulation. If the dicrotic wave amplitude increases, it is confirmed as an effective treatment position (ablation site). After stimulation, select the default parameters: ablation power 8W, ablation time 60s, and temperature control 40℃. After starting ablation, the program will first perform ablation according to the set parameters and record the blood pressure change curve in real time. After ablation, an ablation review interface will automatically pop up, containing data such as the average systolic blood pressure, average diastolic blood pressure, average pulse pressure, average pulse rate, and average dicrotic wave amplitude before ablation in the previous time window, as well as the average systolic blood pressure, average diastolic blood pressure, average pulse pressure, average pulse rate, and average dicrotic wave amplitude after ablation in the next time window. The operator can view the blood pressure change amplitude and dicrotic wave change amplitude. If it is less than a certain threshold (e.g., ...), the operator can view the blood pressure change amplitude and dicrotic wave change amplitude. If the percentage of blood pressure increase is less than 10%, the damage to the sympathetic nerve may be insufficient, indicating that the nerve is buried deeper. If the percentage is greater than or equal to a certain threshold (e.g., 10% but less than or equal to 20%), it indicates that the ablation is effective and the sympathetic nerve is damaged, but the total damage is insufficient. A single stimulation can be performed to aid in assessment. If blood pressure continues to rise during stimulation, the electrode position is slightly adjusted near the previous location to continue ablation. If blood pressure decreases or remains unchanged during stimulation, the position is adjusted to a new location, and the previous steps are repeated to restart stimulation and localization. If the percentage of blood pressure increase is greater than or equal to a certain threshold (e.g., 20%), it indicates significant damage to the sympathetic nerve. In this case, further ablation at selected points can be performed to expand the effect, or the procedure can be terminated. Specifically, after the dicrotic wave amplitude changes by 20%, it is necessary to wait a few minutes to observe whether the effect stabilizes. If the dicrotic wave fluctuation is stable and does not significantly rebound (e.g., the percentage increase in dicrotic wave amplitude is less than or equal to 10%), the procedure can be terminated. Otherwise, stimulation to locate the sympathetic nerve and perform ablation treatment is necessary.
[0107] Furthermore, the ablation device can be combined with a three-dimensional mapping system. Specifically, the distal end of the medical catheter 400 is provided with a positioning sensing element, such as a magnetic positioning sensor or an electrical positioning sensor. By using it in conjunction with the three-dimensional mapping system, a three-dimensional image of the medical catheter 400 and the renal artery can be obtained. The operator can determine the specific location of the medical catheter 400 based on the three-dimensional image, such as at the distal or middle segment of the renal artery.
[0108] Based on the same inventive concept, the present invention also provides a readable storage medium storing a computer program. Please continue to refer to... Figure 9 This is a schematic diagram illustrating the workflow of a readable storage medium provided in one embodiment of the present invention. For example... Figure 9 As shown, when the computer program is executed by the processor, it performs the following steps:
[0109] Step S100: Obtain the preoperative dicrotic wave amplitude information based on the first blood pressure data collected within the first preset time window before the operation.
[0110] Step S200: Control the energy generation module to provide ablation energy to the medical catheter to ablate the target blood vessel.
[0111] Step S300: After each ablation, based on the second blood pressure data collected within the second preset time window after the ablation, obtain the post-ablation dichroic wave amplitude information corresponding to the ablation, and determine whether it is necessary to continue ablation on the target vessel after the ablation based on the pre-ablation dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to the ablation.
[0112] During ablation surgery, when the sympathetic nerve is effectively ablated, a significant decrease in peripheral resistance occurs in the blood vessels it innervates, manifested as a marked change in the dicrotic wave. Therefore, the readable storage medium provided by this invention provides ablation energy to the medical catheter via a control energy generation module to ablate the target blood vessel. It collects first blood pressure data within a first preset time window before the procedure and second blood pressure data within a second preset time window after each ablation. It obtains preoperative dicrotic wave amplitude information based on the first blood pressure data. After each ablation, it obtains post-ablation dicrotic wave amplitude information based on the second blood pressure data. Thus, for each ablation, the surgical effect can be promptly fed back based on the preoperative dicrotic wave amplitude information and the post-ablation dicrotic wave amplitude information, thereby helping the surgeon determine whether the sympathetic nerve has lost its innervation. In summary, the readable storage medium provided by this invention not only facilitates the surgeon's immediate assessment of the ablation effect (denervation effect) during the procedure, effectively reducing the learning curve of the procedure, improving surgical response rate and safety, but also effectively shortens the surgical radiation exposure time, reducing patient discomfort. Furthermore, since the damage to the sympathetic nerves caused by ablation and the effect on vasodilation after the loss of sympathetic nerve innervation are cumulative processes, this invention, by determining whether further ablation of the target vessel is necessary after each ablation based on the post-ablation dichroic wave amplitude information and the pre-operative dichroic wave amplitude information, effectively ensures the accuracy of the determination results.
[0113] In some exemplary embodiments, obtaining preoperative dicrotic wave amplitude information based on first blood pressure data collected within a first preset time window before surgery includes:
[0114] The preoperative dicrotic wave amplitude information is obtained by averaging the amplitudes of each dicrotic wave in the first blood pressure data collected within the first preset time window before surgery.
[0115] In some exemplary embodiments, obtaining the post-ablation dicrotic wave amplitude information corresponding to the ablation based on the second blood pressure data collected within a second preset time window after the ablation includes:
[0116] Based on the average amplitude of each dicrotic wave in the second blood pressure data collected within the second preset time window after the ablation, the ablation post-ablation dicrotic wave amplitude information is obtained.
[0117] In some exemplary embodiments, determining whether to continue ablation of the target vessel after the current ablation, based on the preoperative dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to the current ablation, includes:
[0118] Based on the preoperative dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to this ablation, the dichroic wave amplitude change information corresponding to this ablation is obtained, and based on the dichroic wave amplitude change information corresponding to this ablation, it is determined whether it is necessary to continue ablation on the target vessel after this ablation.
[0119] In some exemplary embodiments, obtaining the dichroic wave amplitude change information corresponding to the ablation based on the preoperative dichroic wave amplitude information and the post-ablation dichroic wave amplitude information corresponding to the ablation includes:

[0137] In summary, compared with the prior art, the ablation device and readable storage medium provided by the present invention have the following beneficial effects:
[0138] During ablation surgery, when the sympathetic nerve is effectively ablated, a significant decrease in peripheral resistance occurs in the blood vessels it innervates, manifested as a marked change in the dicrotic wave. Therefore, this invention employs an energy generation module to provide ablation energy to the medical catheter for ablation of the target blood vessel. A blood pressure monitoring module collects first blood pressure data within a first preset time window before the procedure and second blood pressure data within a second preset time window after each ablation. Preoperative dicrotic wave amplitude information is obtained based on the first blood pressure data. After each ablation, the post-ablation dicrotic wave amplitude information is obtained based on the second blood pressure data. Thus, for each ablation, the surgical effect can be promptly reported based on the preoperative dicrotic wave amplitude information and the post-ablation dicrotic wave amplitude information, helping the surgeon determine whether the sympathetic nerve has lost its innervation. In summary, this invention not only facilitates surgeons' assessment of the immediate ablation effect (denervation effect) during surgery, effectively reducing the learning curve of the procedure, and improving surgical response rate and safety, but also effectively shortens surgical radiation exposure time, reducing patient discomfort. Furthermore, since the damage to the sympathetic nervous system caused by ablation and the effect of vasodilation after loss of sympathetic nerve innervation are cumulative processes, this invention, by determining whether further ablation of the target vessel is necessary after each ablation based on the post-ablation dichroic wave amplitude information and the pre-operative dichroic wave amplitude information, effectively ensures the accuracy of the judgment results.
