[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] In the treatment of cardiovascular diseases, hypertrophic cardiomyopathy is a relatively common and challenging disease. Traditional treatment methods often have many limitations, such as large surgical trauma, high risk, and long recovery time. For patients with hypertrophic cardiomyopathy, myocardial hypertrophy can lead to left ventricular outflow tract obstruction and affect the normal function of the heart. In order to solve this problem, the hypertrophic myocardium needs to be precisely cut to alleviate the symptoms of obstruction.

[0037] However, existing myocardial cutting technologies and devices have the following shortcomings. On the one hand, traditional surgical methods usually require thoracotomy, which causes great trauma to the patient's body and requires extracorporeal circulation support, increasing the risk of surgery and the chance of complications. At the same time, the accuracy of the surgical operation depends on the doctor's experience and technical level, making it difficult to achieve more accurate cutting of myocardial tissue and easily injuring normal myocardial tissue by mistake. On the other hand, there is a lack of effective real-time monitoring and control means. During the operation, key parameters such as the left ventricular outflow tract pressure gradient cannot be accurately monitored, and it is difficult to adjust the cutting parameters in real time according to the patient's specific situation, resulting in unstable surgical results. In addition, existing myocardial cutting devices also have shortcomings in tissue collection and processing. The cut myocardial tissue is often difficult to collect and clean effectively, which brings difficulties to subsequent pathological analysis and other work.

[0038] Glossary:

[0039] The left ventricular outflow tract pressure difference refers to the pressure difference between the left ventricle and the left ventricular outflow tract during blood flow. The left ventricle is the main chamber of the heart responsible for pumping blood to the whole body. During the systole period, the left ventricle contracts strongly to push blood through the left ventricular outflow tract to the aorta, and then transported to all parts of the body. In this process, since blood flow encounters a certain amount of resistance when passing through the left ventricular outflow tract, a pressure difference will be formed between the left ventricle and the left ventricular outflow tract.

[0040] The embodiments of the present application provide a myocardial cutting device and system, which at least solves the problem that the existing myocardial cutting operation is heavily dependent on the doctor's experience and technical level and the cutting accuracy is not high, thereby achieving the purpose of accurate and efficient myocardial cutting.

[0041] The technical solution in the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0042] First, the present application improves the structure of the myocardial cutting device by designing an arc-shaped head end, a cutting groove, etc., so that the hypertrophic tissue can better enter the cavity and be removed; further, by setting an intelligent control module including an ultrasonic monitoring unit, a data analysis unit, and a cutting precision control unit, the pressure difference of the left ventricular outflow tract of the myocardium is collected in real time, and the cutting head is timely controlled to adjust the cutting strategy based on the data to ensure that the cutting operation always matches the real-time state of the heart and improve the cutting accuracy. In addition, by setting a visualization module and electrically connecting it to the intelligent control module, the data collected and generated by the ultrasonic monitoring unit, the data analysis unit, and the cutting precision control unit are visualized; by setting a tissue collection and cleaning module, it is used to collect and clean the cut myocardial tissue in real time, and at the same time start the cleaning function to perform preliminary cleaning on the collected tissue to remove blood and impurities, etc., to prepare for subsequent pathological analysis and other operations.

[0043] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] First, see Figure 1 The present application first proposes a myocardial cutting device, which includes a cutting part 1 and an operation control part 2 ( Figure 1 The cutting part 1 is used to extend into the patient's body to cut the hypertrophic myocardial tissue, and the operation control part 2 is located outside the patient's body and is used to control the cutting action of the cutting part 1.

[0045] like Figure 1-3 As shown, the cutting unit 1 includes a head end 11, a connecting pipe 12, a cutting blade 13, and a front motor 14. One end of the head end 11 passes through a wire and is connected to the operation control unit 2, and the other end is fixedly connected to the connecting pipe 12.

[0046] The connecting pipe 12 has a hollow cavity inside and a cutting groove 15 for allowing all or part of the hypertrophic tissue to enter the cavity. The front motor 14 is arranged in the cavity of the connecting pipe 12 and is located at an end of the connecting pipe 12 away from the operation control unit 2. The output shaft of the front motor 14 is connected to one end of the cutting knife 13. When the front motor 14 is working, the cutting knife 13 is driven to move to cut the hypertrophic tissue entering the cutting groove 15 in the cavity.

[0047] The operation control unit 2 includes a power supply, which is electrically connected to the front motor 14 through the wire to provide power to the front motor 14 to drive the cutting blade 13 to move.

[0048] In one embodiment, the head end 11 is an arc-shaped structure, and the arc-shaped design of the head end 11 enables it to better fit the heart surface.

[0049] In another embodiment, the output shaft of the front motor 14 is fixed to the handle of the cutting knife 13 through a cylindrical cam mechanism 16. The cylindrical cam mechanism 16 can convert the rotational motion of the output shaft of the front motor 14 into a linear motion, thereby driving the cutting knife 13 to move back and forth along a straight line, thereby achieving cutting of the hypertrophic myocardial tissue at the cutting edge. Figure 4 .

[0050] When performing a myocardial cutting operation, the cutting part 1 is first inserted into the patient's body through the esophagus (or other appropriate routes, such as through a sheath), extended and close to the hypertrophic myocardial tissue of the patient's heart, and the arc-shaped design of the head end 11 enables it to better fit the surface of the heart. When the hypertrophic tissue is in a natural state, or is squeezed in whole or in part by the connecting pipe 12, or under other guiding methods, it enters the cavity of the head end 11 and the resection groove 15 in whole or in part, the front motor 14 located in the cavity is energized to drive the cutting knife 13 to cut the hypertrophic tissue entering the cavity.

[0051] In another embodiment, in order to avoid damage to the patient's normal tissue during the process of the cutting part 1 being inserted into the patient's body, it is preferably set that the total length of the two ends of the axis of the cylindrical cam mechanism 16 is the shortest when the front motor 14 stops rotating, thereby ensuring that when the motor stops working, the blade head of the cutting knife 13 can be recovered into the connecting pipe 12, so as to avoid damage to the patient's normal tissue during the process of the cutting part 1 being inserted or removed.

[0052] In a second aspect, the present application also proposes a myocardial cutting system, such as Figure 5 As shown, the system includes the myocardial cutting device, and on the basis of the myocardial cutting device, further includes: an intelligent control module, wherein the intelligent control module is integrated in the operation control unit 2 .

[0053] The intelligent control module is used to analyze the acquired cutting data and generate motor control instructions based on the data analysis results. Specifically, the intelligent control module includes an ultrasonic monitoring unit, a data analysis unit, and a cutting precision control unit. Among them, the ultrasonic monitoring unit, the data analysis unit and the cutting precision control unit are electrically connected in sequence. Specifically, the ultrasonic monitoring unit is used to monitor the left ventricular outflow tract pressure difference in real time and transmit the monitoring data to the data analysis unit. After analyzing the data, the data analysis unit sends instructions to the cutting precision control unit, thereby controlling the precision (such as cutting speed, depth, etc.) during the cutting process.

[0054] In one embodiment, the intelligent control module integrated with the ultrasonic monitoring unit, the data analysis unit and the cutting precision control unit is connected to the cutting part 1 of the myocardial cutting device through a connecting cable. The connecting cable can provide a stable and reliable signal transmission channel to ensure that the data exchange between the myocardial cutting device and the intelligent control module is relatively accurate, which is crucial for real-time monitoring and precise control of the surgical process, avoiding signal interference and data loss that may occur in wireless transmission, and improving the safety and reliability of the surgery.

[0055] The ultrasound monitoring unit uses ultrasound technology to obtain information about the internal structure and blood flow of the heart by emitting ultrasound waves and receiving reflected waves. During the operation, the ultrasound monitoring unit continuously focuses on the left ventricular outflow tract area and measures the pressure changes in the left ventricular outflow tract in real time. The ultrasound monitoring unit includes an ultrasound probe, which continuously emits high-frequency ultrasound waves. These ultrasound waves will produce different degrees of reflection when encountering different media such as heart tissue and blood. After the reflected ultrasound waves are received by the ultrasound monitoring unit, they are analyzed and processed by the data analysis unit, and the left ventricular outflow tract pressure difference data is obtained. The monitored pressure difference data will be transmitted to the cutting precision control unit in real time in the form of digital signals, providing key decision-making basis for the cutting strategy adjustment of the cutting precision control unit.

[0056] By setting up an ultrasonic monitoring unit, the left ventricular outflow tract pressure difference can be monitored in real time, allowing doctors to promptly understand changes in the patient's heart status. Once an abnormal situation occurs, such as the pressure difference is too high or too low, the doctor can immediately take appropriate measures to avoid serious damage to the heart during surgery. The cutting accuracy control unit adjusts the cutting process and cutting accuracy based on the ultrasonic monitoring data to ensure that the operation is performed within a safe range, greatly reducing the risk of surgery.

[0057] The data analysis unit is used to process and analyze data during the operation, including analysis of left ventricular outflow tract pressure gradient, cutting parameters, etc., and provide operation guidance and decision support.

[0058] During the operation, the data analysis unit continuously receives the left ventricular outflow tract pressure difference data, cutting parameters and other related data from the ultrasound monitoring unit, processes and analyzes these data using the data analysis method, and generates instructions for controlling the cutting accuracy adjustment based on the data analysis results. In a preferred embodiment, the data analysis unit includes an STM32 microcontroller.

[0059] In the prior art, pressure sensors are often used to measure changes in pressure at a specific location on myocardial hypertrophic tissue, and this is used as an analysis basis to guide the cutting of myocardial hypertrophic tissue. However, this approach of relying solely on a pressure sensor to measure changes in pressure at a specific location ignores the effects of factors such as the cutting area and cutting time on the pressure difference during myocardial cutting. This single factor cannot fully reflect the complex hemodynamic changes during surgery, and can easily lead to inaccurate assessments of cutting accuracy. In order to avoid and solve this problem, the present embodiment embeds a memory that stores algorithms and programs in the data analysis unit, comprehensively considers the effects of pressure difference, cutting area, and cutting time on the left ventricular outflow tract pressure difference, and uses a formula to accurately calculate the patient's left ventricular outflow tract pressure difference.

[0060] When a patient is undergoing myocardial hypertrophy tissue cutting, pressure difference, cutting area and cutting time are three key factors that affect cutting safety. Pressure difference reflects the change in pressure inside the heart during the operation, while cutting area and cutting time are directly related to the cutting operation. In order to further improve the cutting progress, a preferred method is that the algorithm and program stored in the memory include calculating the left ventricular outflow tract pressure difference using the following formula:

[0061] PLVOT=ΔP*A*t

[0062] Among them, PLVOT represents the left ventricular outflow tract pressure difference, ΔP represents the pressure difference, A represents the cutting area, and t represents the cutting time. When the cutting area A or the cutting time t is adjusted, the left ventricular outflow tract pressure difference PLVOT will also be adjusted accordingly, thereby feeding back the changes in the cutting area A or the cutting time t, and the changes in the cutting area A or the cutting time t can indirectly reflect the changes in the cutting depth and speed to meet the needs of the operation.

[0063] The formula of left ventricular outflow tract pressure difference PLVOT=ΔPxAxt comprehensively considers the three key factors of pressure difference (ΔP), cutting area (A) and cutting time (t). Through this comprehensive consideration, it can more comprehensively reflect the changes in left ventricular outflow tract pressure difference during myocardial cutting, and provide a more accurate basis for cutting precision control. In addition, the left ventricular outflow tract pressure difference is calculated in real time during the operation. As the cutting knife moves, the cutting area and cutting time change continuously, and the dynamic changes of the pressure difference can be recalculated immediately according to the change value. This real-time dynamic adjustment capability enables the cutting precision control unit to adjust the cutting depth and speed of the cutting knife in time according to the calculation results of the formula, ensuring that the cutting operation always matches the real-time state of the heart and improves the cutting precision.

[0064] Through the trend analysis of the left ventricular outflow tract pressure difference data, the changes in cardiac function during the operation can be judged; the statistical analysis of the cutting parameters can be used to evaluate the cutting effect and efficiency. Based on the analysis results, operation guidance and decision support information can be generated. This information may include suggestions for adjusting cutting parameters and reminding doctors to pay attention to surgical risks. During the myocardial cutting process, the data analysis unit provides doctors with scientific decision support, helping them to better understand the surgical situation and make more informed decisions. Through the analysis of a large amount of data, the system can provide more accurate and reliable operation guidance, improve the success rate of the operation, and the operation guidance information can help doctors make decisions quickly and reduce the operation time.

[0065] In addition, through the formula algorithm, the cutting depth and speed of the cutting knife can be accurately adjusted according to the real-time monitoring data, which makes the operation safer and more accurate, avoids over-cutting or under-cutting, and improves the success rate of the operation. Different patients and surgical conditions may require different cutting depths and speeds. The formula algorithm can flexibly adjust the cutting area and cutting time according to the specific situation to meet different surgical needs.

[0066] The cutting precision control unit controls the cutting depth and cutting speed of the cutting knife according to the control instructions issued by the data analysis unit.

[0067] The cutting precision control unit is electrically connected to the front motor 14, and adjusts the cutting strategy by adjusting the values ​​of the cutting area A and the cutting time t. For example, at the beginning of the operation, the cutting knife may perform initial cutting with a smaller cutting area and a shorter cutting time. At this time, the left ventricular outflow tract pressure difference is monitored to be small, and the cutting area A and / or cutting time t can be appropriately increased to increase the cutting depth and speed to ensure the effect of the operation; as the operation progresses, the cutting area and cutting time increase. At this time, the left ventricular outflow tract pressure difference is monitored to increase and exceed the safety value. At this time, it is necessary to appropriately reduce the cutting area A and / or cutting time t to avoid excessive damage to the heart. In other stages of the cutting operation, it may be necessary to adjust the cutting area A and / or cutting time t accordingly according to the size of the left ventricular outflow tract pressure difference monitored. Specifically, the real-time monitored left ventricular outflow tract pressure difference is compared with the safety value of the left ventricular outflow tract pressure difference, and then the cutting strategy is re-formulated according to the size of the situation (such as adjusting the cutting area and / or cutting time to make the real-time monitored left ventricular outflow tract pressure difference tend to the safety value of the left ventricular outflow tract pressure difference), thereby providing the cutting precision control unit with immediate decision-making basis, so that the cutting operation can accurately adapt to various changes during the operation.

[0068] In addition, the cutting area A can be changed by controlling the range of motion of the cutting blade 13, adjusting the angle of the cutting blade 13, or replacing the cutting blade 13 with a different size. For example, the cutting area and cutting depth can be controlled by controlling the displacement and pressure of the cutting blade in the cutting direction and perpendicular to the cutting direction. The cutting time can be adjusted by adjusting the movement speed of the cutting blade 13, changing the duration of the cutting, etc. For example, the cutting speed can be controlled by controlling the current of the driving motor and then controlling the motor speed.

[0069] In a further embodiment, the myocardial cutting system further comprises a visualization module.

[0070] The visualization module is electrically connected to the intelligent control module, and visualizes the data collected and generated by the ultrasonic monitoring unit, the data analysis unit, and the cutting precision control unit.

[0071] In a further embodiment, the myocardial cutting system further comprises: a tissue collection and cleaning module for collecting and cleaning the cut myocardial tissue in real time. The tissue collection and cleaning module is located in a hollow cavity inside the connecting pipe 12 and is arranged below the cutting groove 15 .

[0072] As the cutting proceeds, the cut myocardial tissue is collected in real time by the tissue collection and cleaning module below the resection groove 15. Among them, the tissue collection and cleaning module includes a collection tank, in which a cleaning solution (the cleaning solution includes physiological saline, etc.) is stored, and a miniature ultrasonic vibration cleaning machine is located in the cleaning solution of the collection tank. The cut myocardial tissue falls into the cleaning solution in the collection tank, and the miniature ultrasonic vibration cleaning machine generates vibrations during operation to clean the cut myocardial tissue. In one embodiment, the tissue collection and cleaning module is electrically connected to the above-mentioned cutting accuracy control unit, and is started, stopped and turned off at the same time as the front motor to maintain the same frequency (the cutting speed of the cutting knife and the vibration frequency of the ultrasonic vibration cleaning machine maintain the same trend, the faster the cutting speed, the higher the vibration frequency; conversely, the slower the cutting speed, the lower the vibration frequency), to ensure that the cutting and cleaning of the myocardial tissue are synchronized.

[0073] The tissue collection and cleaning module uses its specific structure and working mode to quickly collect the cut myocardial tissue and simultaneously activate the cleaning function to perform preliminary cleaning of the collected tissue to remove blood and impurities, etc., in preparation for subsequent pathological analysis and other operations.

[0074] The myocardial cutting system provided in the above embodiment can receive instructions from the intelligent control module through the cutting accuracy control unit of the operation control unit 2 to realize the control of the front motor 14, and can adjust the cutting parameters such as cutting speed and force according to different surgical requirements to improve the flexibility and adaptability of the operation. The tissue collection and cleaning module arranged under the resection groove 15 can collect and clean the cut myocardial tissue in real time to avoid tissue scattering and loss. At the same time, preliminary cleaning can facilitate subsequent pathological analysis and other operations, reduce the risk of infection, and improve the safety and reliability of the operation.
