Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a quality assessment and monitoring system and method based on the temperature and pressure of a vascular anastomosis site. Background Art

[0002] In recent decades, with the development of microsurgery, the surgical procedures for replantation of amputations (broken fingers / arms / limbs) in different planes of the human body have been highly standardized, with a replantation success rate of over 80%. The most important factor that determines the success of replantation is the vascular anastomosis technique. If the quality of vascular anastomosis is poor, vascular spasm or embolism will often occur, often leading to replantation failure, often requiring another surgery, and even putting the patient at risk of finger / limb amputation. High-quality vascular anastomosis technology can ensure the patency of the vascular anastomosis.

[0003] How to judge the patency of the anastomosis is a key parameter for evaluating the success of finger replantation. The diameters of blood vessels in the human body vary. The diameters of the thicker thoracic aorta and abdominal aorta can reach 20-30mm, the diameters of the femoral artery, brachial artery, and popliteal artery are 3-5mm, the diameters of the ulnar artery, radial artery, and dorsalis pedis artery are 2-3mm, and the diameter of the thinnest digital artery in the body is only 0.2mm. Clinically, blood vessels with a lumen diameter of less than 2-3mm need to be sutured under a microscope to ensure the patency of the anastomotic ends. However, at this stage, the main technical means to evaluate the quality of vascular anastomosis under a microscope is the surgeon's subjective judgment, which lacks objective support and is highly dependent on the surgeon's own experience. In addition, the following technologies currently exist:

[0004] High-speed camera-assisted evaluation system

[0005] High-speed cameras with a speed of 1000 frames per second are used to collect high-frame image data, quickly identify the refilling process of the anastomotic blood vessels, and quickly calculate the relative length of the blood vessels and the blood vessel filling time, thereby quickly calculating the blood vessel refilling rate ratio. This technology can achieve instant observation of the patency of the anastomotic blood vessels during surgery, but it cannot achieve continuous observation of the anastomotic blood vessels after surgery.

[0006] Laser Doppler flowmeter

[0007] Using probes of various sizes, the laser beam is directed to the anastomosis site, and the light is scattered back to the probe by red blood cells with Doppler shift; it is returned to the detector, which determines the percentage of backscattered light to assess blood flow patency. This technology can detect the flow of anastomotic blood vessels, but it cannot be observed in real time and dynamically.

[0008] Indocyanine green angiography

[0009] 3-5 mL of indocyanine green is injected intravenously, and a near-infrared light source is used to excite the indocyanine green molecules at the anastomosis, thereby generating fluorescence that is captured by a digital camera to assess blood flow patency. The implementation of this technology requires intravenous injection of contrast agents, which may cause adverse reactions such as allergies, nausea, and fever.

[0010] In order to solve the above problems, we proposed a quality assessment and monitoring system and method based on the temperature and pressure of the vascular anastomosis site, which can monitor the tension of the vascular wall after blood flow is restored at the proximal and distal ends of the vascular anastomosis, and effectively evaluate the quality of vascular anastomosis. Summary of the invention

[0011] In view of the deficiencies of the prior art, the present invention provides a quality assessment and monitoring system and method based on the temperature and pressure of the vascular anastomosis site to solve the problems raised in the above background technology.

[0012] To achieve the above-mentioned object, the present invention provides the following technical solutions: a quality assessment and monitoring system based on the temperature and pressure of the vascular anastomosis site, comprising an implanted detection unit, a wireless receiver module and a vascular anastomosis quality analysis platform, wherein the implanted unit transmits the detected temperature data to the vascular anastomosis quality analysis platform based on the wireless receiver module;

[0013] The implant detection unit includes a flexible temperature / pressure sensing module and a wireless transmission module, which are implanted on the surface of the blood vessel. The flexible temperature / pressure sensing module is used to detect the temperature / pressure data of four key points of the blood vessel anastomosis site, and the wireless transmission module is used to send the temperature / pressure data to the wireless receiver module.

[0014] The wireless receiver module is used to receive the temperature / pressure data transmitted by the wireless transmitter module, and transmit the temperature / pressure data to the vascular anastomosis quality analysis platform;

[0015] The vascular anastomosis quality analysis platform is used to receive temperature / pressure data from the wireless receiver module, compare the temperature / pressure data of four key points at the vascular anastomosis site, and analyze the temperature / pressure difference between the key points corresponding to the far and near ends of the anastomosis site.

[0016] To further optimize the technical solution, the four key points of the vascular anastomosis site are formed based on the two-point interrupted suturing method, and one stitch is sutured at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock directions of the broken end of the vascular lumen. The suture needles at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock directions are the four key points of the vascular anastomosis site.

[0017] To further optimize the technical solution, the four key points of the vascular anastomosis site are used to judge the quality of the vascular anastomosis;

[0018] When the quality of vascular anastomosis is good, the blood flow is smooth, and the surface temperature / pressure of the blood vessels at the four key points at both ends of the anastomosis tend to be the same;

[0019] When the quality of vascular anastomosis is poor, blood flow is not smooth, and there are significant differences in the surface temperature / pressure of the blood vessels at the four key points at the far and near ends of the anastomosis.

[0020] To further optimize the technical solution, the flexible temperature / pressure sensing module includes a flexible substrate, a resistance temperature measurement array, a pressure acquisition module and a temperature acquisition module. The flexible substrate is attached to the surface of the vascular anastomosis site, and the resistance temperature measurement array, the pressure acquisition module and the temperature acquisition module are all integrated on the flexible substrate.

[0021] To further optimize the technical solution, the flexible substrate is customized according to the sizes of different parts of the human body and blood vessels to ensure that it fits the surface of the blood vessels to reduce the impact on blood flow; the resistance temperature measurement array performs accurate temperature measurement at four key points of the vascular anastomosis site; the temperature acquisition module is used to collect temperature data measured by the resistance temperature measurement array, and the pressure acquisition module is used to collect pressure data and send it to the vascular anastomosis quality analysis platform through the wireless transmission module.

[0022] To further optimize the technical solution, the wireless transmission module includes a radio frequency transceiver and an implantable antenna, both of which are integrated on a flexible substrate, and the wireless transmission module uses a Bluetooth or Wi-Fi chip to achieve wireless transmission of temperature data.

[0023] To further optimize the technical solution, the wireless receiver module includes a receiving antenna and a transceiver chip. The wireless receiver module not only receives temperature / pressure data, but is also responsible for transmitting the received temperature / pressure information to the vascular anastomosis quality analysis platform. The receiving antenna has high sensitivity and low interference functions, and is used to accurately receive weak signals from the flexible temperature / pressure sensing module.

[0024] To further optimize the technical solution, the vascular anastomosis quality analysis platform includes the following specific contents when comparing and analyzing the temperature / pressure data:

[0025] If the temperature difference is within 0.5 to 1.5°C, the suture quality is considered good;

[0026] If the temperature difference exceeds 1.5°C, the suture quality is considered poor, and the doctor will decide whether the operation needs to be repeated;

[0027] If the pressure difference is within the preset threshold, the suture quality is considered good;

[0028] If the pressure difference exceeds the preset threshold, the suture quality is deemed poor, and the doctor will decide whether reoperation is necessary.

[0029] To further optimize the technical solution, the vascular anastomosis quality analysis platform also includes a visualization module, which is used to provide a graphical temperature / pressure distribution diagram to assist doctors in intuitively understanding the conditions of the anastomotic site.

[0030] A quality assessment and monitoring method based on the temperature and pressure of a vascular anastomosis site is operated based on the above-mentioned quality assessment and monitoring system based on the temperature and pressure of a vascular anastomosis site, and includes the following specific steps:

[0031] S1. System configuration and installation

[0032] Select the appropriate model of flexible temperature / pressure sensing module, ensuring that its size matches the diameter of the surgical vessel;

[0033] Install the flexible temperature / pressure sensing module at the vascular anastomosis site to ensure that the resistance temperature measurement array and pressure acquisition module accurately cover the 3 o'clock, 6 o'clock, 9 o'clock and 12 o'clock positions;

[0034] Turn on the wireless transmission module, ensure that the RF transceiver and implantable antenna are working properly, and perform preliminary functional tests to verify signal stability and transmission efficiency;

[0035] S2. Data collection and transmission

[0036] Perform surgical anastomosis operations and continuously monitor the temperature / pressure data of the anastomosis site;

[0037] The temperature / pressure data of the anastomotic site are collected in real time through the temperature acquisition module and the pressure acquisition module on the flexible substrate;

[0038] The collected data is wirelessly transmitted to an external wireless receiver module through a wireless transmitter module;

[0039] S3. Data reception and analysis

[0040] Using a wireless receiver module to receive temperature / pressure data transmitted from a flexible temperature / pressure sensing module;

[0041] sending the received data to a vascular anastomosis quality analysis platform;

[0042] The analysis platform processes and analyzes the data, comparing the temperature / pressure differences at different points in the anastomosis area;

[0043] S4. Result evaluation and feedback

[0044] The anastomosis quality is judged based on the analysis results. If the temperature difference of each corresponding point is within 0.5 to 1.5 degrees, and the pressure difference is within the preset threshold, the anastomosis quality is evaluated as excellent. If the temperature difference is greater than 1.5 degrees, or the pressure difference exceeds the preset threshold, it indicates that re-suturing may be required.

[0045] The analysis platform provides detailed temperature / pressure distribution diagrams and quality assessment reports for doctors’ reference;

[0046] Based on the evaluation results, the doctor decides whether the anastomosis site needs to be adjusted or the operation needs to be repeated;

[0047] S5. System maintenance and subsequent monitoring

[0048] After the operation is completed, regularly check and maintain the wireless transmission and reception equipment to ensure its continued effective operation;

[0049] Perform a final system check before the patient is discharged to confirm that there are no abnormalities in each module;

[0050] Provides necessary patient follow-up and remote monitoring services to continuously assess the recovery of the anastomosis site.

[0051] Compared with the prior art, the present invention provides a quality assessment and monitoring system and method based on the temperature and pressure of the vascular anastomosis site, which has the following beneficial effects:

[0052] This quality assessment and monitoring system and method based on the temperature and pressure of the vascular anastomosis site can monitor and accurately analyze the temperature differences at the surgical anastomosis site in real time, thereby providing doctors with key data to evaluate the anastomosis quality. It not only improves the success rate of the operation and reduces the risk of postoperative complications, but also can effectively guide doctors to make immediate adjustments during the operation to ensure the optimal result of the operation. The system can also continuously monitor the recovery of the anastomosis site and provide a scientific basis for subsequent treatment, thereby greatly improving the patient's treatment experience and rehabilitation quality.

[0059] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0060] Embodiment 1:

[0062] The implant detection unit includes a flexible temperature / pressure sensing module and a wireless transmission module, which are implanted on the surface of the blood vessel. The flexible temperature / pressure sensing module is used to detect the temperature / pressure data of four key points of the blood vessel anastomosis site 2, and the wireless transmission module is used to send the temperature / pressure data to the wireless receiver module.

[0063] The flexible temperature / pressure sensing module includes a flexible substrate 3, a resistance temperature measurement array, a pressure acquisition module and a temperature acquisition module.

The wireless transmission module uses a Bluetooth or Wi-Fi chip to achieve wireless transmission of temperature / pressure data. The design of the implantable antenna should take into account miniaturization and high efficiency to adapt to the vascular environment and ensure stable signal transmission. The design of the antenna should also take into account the impact of blood vessels on antenna impedance matching and radiation efficiency to optimize transmission performance.

[0073] In this embodiment, the vascular anastomosis quality analysis platform includes the following specific contents when comparing and analyzing the temperature / pressure data:

[0074] If the temperature difference is within 0.5 to 1.5°C, the suture quality is considered good;

[0075] If the temperature difference exceeds 1.5°C, the suture quality is considered poor, and the doctor will decide whether the operation needs to be repeated;

[0076] If the pressure difference is within the preset threshold, the suture quality is considered good;

[0077] If the pressure difference exceeds the preset threshold, the suture quality is deemed poor, and the doctor will decide whether reoperation is necessary.
