Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an intelligent adjustable vascular closure system. Background Technology

[0002] In modern surgical procedures, vascular closure is a crucial operation, and its effectiveness directly affects the safety and success rate of the surgery.

[0003] Currently, traditional vascular closure systems have many shortcomings: On the one hand, during the surgical procedure, medical staff have difficulty accurately controlling the clamping force and the intensity of the operation. For example, when clamping blood vessels, if the clamping force is too small, the blood vessels cannot be effectively closed, leading to an increased risk of bleeding; if the clamping force is too large, it may damage the blood vessel wall, affect the subsequent functional recovery of the blood vessel, or even cause serious complications such as blood vessel rupture.

[0004] On the other hand, existing vascular closure systems lag behind in equipment management and inventory control. Data recording of vascular clamp usage is incomplete and inaccurate, making it difficult to perform scientific maintenance and updates based on actual equipment usage. Therefore, it is necessary to propose an intelligent, adjustable vascular closure system capable of accurately sensing surgical parameters, intelligently analyzing them, and providing effective feedback, which has significant clinical implications and meets practical needs. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent adjustable vascular closure system to solve the problem of difficulty in accurately controlling surgical operation parameters in the prior art, thereby improving the safety and effectiveness of vascular closure surgery.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An intelligent adjustable vascular closure system includes a vascular clamp and a functional module, wherein the vascular clamp and the functional module are electrically connected and work together. The vascular clamp includes a pressing handle, one end of which is fixedly connected to a clamping arm, and the end of the clamping arm is fixedly connected to a clamp head. The clamp heads are staggered and connected by screws. A self-destructing locking device is provided between the pressing handles. A silicone pad is provided on the outer wall of the clamp head, and a pressure-sensitive thin-film sensor is arranged between the silicone pad and the clamp head. A handle vibration device that cooperates with the pressure-sensitive thin-film sensor is provided on the inner wall of the pressing handle. The functional modules include a data acquisition module, an execution linkage control module, a hardware detection module, a data analysis module, and an equipment management module; The data acquisition module is connected to the pressure-sensitive film sensor, the handle vibration component, and the surgery-related information source to collect clamping force, operating force, and surgery-related data and perform preprocessing. The hardware detection module monitors the operating status of hardware components within the system, determines whether the hardware is working properly by sending detection signals and monitoring operating parameters, and issues prompts and records data when abnormalities occur. The data analysis module receives data transmitted from the data acquisition module, analyzes the clamping force, operating force, and vascular imaging data, outputs the analysis results and generates analysis suggestions, and uses them as surgical-related data. The execution linkage control module receives surgical-related data, controls the display device to display surgical operation-related information, and links with the execution equipment to control its actions.

The system monitors the operating current (I) and voltage (U) of hardware components in real time; it sets a preset normal range for the signal deviation rate and sets rated standard values ​​for the operating current and voltage; if the signal deviation rate is not within its preset normal range, or if the deviation between the operating current / voltage and its corresponding rated standard value exceeds its deviation threshold, it determines a hardware malfunction and generates a prompt signal, while simultaneously recording the malfunction event and parameter values; The actual response signal value received. This is the preset standard response signal value.

[0009] Preferably, the analysis process of the data analysis module includes: Clamping force analysis: Obtaining the real-time clamping force on the target blood vessel.

The adaptation range is obtained by calculating the difference between the maximum and minimum real-time adaptation scores within a preset unit time. The adaptation fluctuation value is obtained by calculating the real-time adaptation degree within a preset unit time using the standard deviation formula. The adaptation evaluation value M is obtained by weighting the real-time adaptation degree, adaptation range, and adaptation fluctuation value. When the adaptation evaluation value exceeds its preset deviation adaptation range, the clamp adjustment suggestion is output.

[0010] Preferably, the execution linkage control module includes a display control submodule and a device linkage submodule, as detailed below: The display control submodule receives the clamping force assessment value F output by the data analysis module, presets safety thresholds A and B, and performs graded display: When F≤A, the control display device displays the first color and the "operation safe" status indicator, and simultaneously displays the basic data of vascular image adaptation and operation force transmission coefficient. When A < F ≤ B, the control display device flashes in the second color and displays a warning pop-up window that says "Operation requires caution, approaching the safety threshold," showing the clamping force trend curve, the real-time value of the operating force, and its changing trend. When F > B, the control display device displays in the third color, forcibly pops up the message "Clamping force exceeds limit, adjust operation immediately", freezes non-emergency operation buttons, and restores interface interaction after medical staff confirm and adjust the operation; The device linkage submodule obtains the blood vessel diameter. Clamping width of the chuck Calculate the theoretically adapted clamping width Based on the mechanical linkage parameter p between the chuck and the clamping arm, the final clamping arm adjustment amount is calculated using a preset formula. When the final adjustment of the clamping arm exceeds its arm length threshold, a clamping arm adjustment prompt is generated, and the final adjustment of the clamping arm is displayed on the display device.

[0011] Preferably, the device management module includes: The production information and sterilization date of the vascular clamp are linked by a unique identifier; the usage time t and number of operations N of the vascular clamp are recorded for each surgery, and the equipment utilization rate is calculated using a preset formula. And count the total number of uses within the preset period; The frequency of equipment use is calculated using a preset formula. ; The inventory quantity Q of the vascular clamp is synchronized with the material management system, and the inventory warning threshold Qn is dynamically adjusted based on the usage rate U and usage frequency F: When both U and F are higher than the preset high threshold, the inventory warning threshold of the set value is increased; When both U and F are below the preset low threshold, the set inventory warning threshold is lowered. When Q≤Qn, a replenishment prompt for the blood vessel clamp is triggered, which helps generate a procurement plan.

[0012] Preferably, the clamping arm includes a hollow clamping arm and a movable clamping arm.

[0014] Compared with related technologies, the intelligent adjustable blood vessel closure system provided by the present invention has the following beneficial effects: 1. Through the collaborative work of various functional modules, the data acquisition module acquires force signals in real time and preprocesses them, the data analysis module generates evaluation values ​​through multi-dimensional calculations, and the execution linkage control module displays and provides feedback on risks in a graded manner. The three work together to achieve quantitative monitoring and dynamic early warning of clamping force and operating force, avoiding vascular rupture or closure failure caused by improper force, and improving surgical safety.

[0015] 2. The brittle plastic hook design of the self-destructing locking buckle restricts the equipment to a single use, avoiding the risk of cross-infection caused by repeated use; the sliding fit between the hollow clamp arm and the movable clamp arm, as well as the self-locking structure, supports multi-level adjustment of the clamp arm length, adapting to different diameter blood vessels and surgical scenarios, reducing the frequency of instrument replacement, and shortening the tissue exposure time.

[0016] 3.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figure 1 - Figure 5 The present invention provides a technical solution: An intelligent adjustable vascular closure system includes a vascular clamp and a functional module, wherein the vascular clamp and the functional module are electrically connected and work together. The vascular clamp includes a pressing handle 5, with a clamping arm 3 fixedly connected to one end of the pressing handle 5. A clamp head 1 is fixedly connected to the end of the clamping arm 3, and the clamp heads 1 are staggered and connected by screws 2. A self-destructing locking mechanism 4 is provided between the pressing handles 5. The self-destructing locking mechanism 4 is used to restrict the reuse of the vascular clamp, preventing incomplete disinfection due to irreversible structural damage after a single surgical operation, and reducing the risk of cross-infection for patients. A silicone pad 6 is provided on the outer wall of the clamp head 1, which directly contacts the blood vessel, utilizing its elastic cushioning properties to reduce the impact of the clamp head 1 on the blood vessel wall. To prevent hard damage and increase friction to prevent blood vessel slippage, a pressure-sensitive film sensor is arranged between the silicone pad 6 and the clamp 1. The inner wall of the pressing handle 5 is equipped with a handle vibration component 7 that cooperates with the pressure-sensitive film sensor. The pressing handle 5 provides a gripping fulcrum for medical staff, and the clamp arm 3 is driven to move by applying gripping force. The clamp arm 3 acts as a force transmission component, transmitting the operating force of the pressing handle 5 to the clamp 1. The staggered clamps 1 are fixed by screws 2 to form a clamping space, achieving stable clamping of blood vessels. The screw connection ensures the structural rigidity of the clamp 1 and avoids deformation during clamping. In this application, the clamping arm 3 includes a hollow clamping arm 301 and a movable clamping arm 302. The hollow clamping arm 301 is disposed at the end of the pressing handle 5, and the movable clamping arm 302 is slidably disposed within the hollow clamping arm 301 and fixedly connected to the clamp head 1. The hollow clamping arm 301 provides support and a sliding guide track for the movable clamping arm 302. The movable clamping arm 302 changes the overall length of the clamping arm 3 by sliding relative to the hollow clamping arm 301, adapting to the clamping needs of blood vessels of different diameters, such as arteries and veins, and surgical sites, thereby improving the versatility of the device. The end of the movable clamping arm 302 is provided with a self-locking component, which includes a hollow cavity 304 opened at the end of the movable clamping arm 302, a locking block 307 slidably disposed within the hollow cavity 304, and a spring 306. Multiple locking blocks 307 are evenly distributed on the inner wall of the hollow clamping arm 301. The inclined groove 303 of the 07-fitting clamp; the self-locking component fixes the clamp arm after length adjustment, and the spring 306 provides elastic thrust to the locking block 307, so that it is locked into the inclined groove 303 of the hollow clamp arm 301, and the sliding of the movable clamp arm 302 is restricted by mechanical engagement; the inclined groove 303 is evenly distributed to form a multi-level adjustment position to meet the length adjustment requirements of different precision; the inclined groove 303 is also provided with a rubber pad 308 to increase the friction between the locking block 307 and the inclined groove 303, so as to prevent the clamp arm of the vascular clamp from moving downward during use, thereby ensuring the stability of the clamp arm of the vascular clamp and facilitating the normal use of the vascular clamp; the bottom surface of the hollow clamp arm 301 has a strip-shaped opening 305, and the bottom surface of the locking block 307 has a circular rod 309 that passes through the strip-shaped opening 305.

[0022] In this application, the self-destructing locking device 4 includes a connecting post 401, a strip cavity 402, a connecting rod 405, a hook 404, and a plastic post 403. The connecting post 401 is disposed between the pressing handles 5. The strip cavity 402 is formed inside the connecting post 401. The connecting rod 405 is slidably disposed at both ends of the strip cavity 402 and its outer end is connected to the pressing handle 5. The hook 404 is fixedly connected to the inner end of the connecting rod 405. The plastic post 403 is disposed in the middle of the strip cavity 402 and cooperates with the hook 404. The hook 404 is made of brittle plastic. The connecting post 401 provides structural support for the locking device, and the strip cavity 402 provides sliding space for the connecting rod 405. The connecting rod 405 transmits the opening and closing action of the pressing handle 5 to the inside of the locking device. When the pressing handle 5 closes and clamps the blood vessel, it drives the connecting rod 405 to slide in the strip cavity 402, triggering the locking mechanism. When the pressing handle 5 is closed, the connecting rod 405 drives the hook 404 to engage the plastic column 403 to achieve temporary locking, preventing the pressing handle 5 from being accidentally released during clamping; when disassembling after the operation, the hook 404 is subjected to tensile force and undergoes brittle fracture, making it unable to engage the plastic column 403 again, causing the locking mechanism to permanently fail and achieving the single-use limitation of the equipment.

[0024] Please refer to the following: Figure 3As shown, based on the intelligent adjustable vascular closure system provided in Embodiment 1 of this application, Embodiment 2 of this application proposes another intelligent adjustable vascular closure system. Embodiment 2 is merely a preferred embodiment of Embodiment 1, and the implementation of Embodiment 2 will not affect the individual implementation of Embodiment 1.

[0025] Specifically, the difference in the intelligent adjustable blood vessel closure system provided in Embodiment 2 of this application is that the functional modules include a data acquisition module, an execution linkage control module, a hardware detection module, a data analysis module, and a device management module; The data acquisition module is connected to the pressure-sensitive film sensor, the handle vibration component 7, and the surgery-related information source to collect clamping force, operating force, and surgery-related data and perform preprocessing. The hardware detection module monitors the operating status of hardware components within the system, determines whether the hardware is working properly by sending detection signals and monitoring operating parameters, and issues prompts and records data when abnormalities occur. The data analysis module receives data transmitted from the data acquisition module, analyzes the clamping force, operating force, and vascular imaging data, outputs the analysis results and generates analysis suggestions, and uses them as surgical-related data. The execution linkage control module receives surgical-related data, controls the display device to display surgical operation-related information, and links with the execution equipment to control its actions. The equipment management module assigns a unique identifier to the blood vessel clamp, associates it with detailed information about the blood vessel clamp, connects with relevant systems to obtain the status information of the blood vessel clamp, collects, records, stores, and analyzes equipment usage data, and interacts with the material management system to achieve inventory management.

By providing early warnings, it can avoid surgical risks such as inaccurate clamping force detection and operation feedback failure caused by hardware abnormalities, ensuring stable system operation and surgical safety. At the same time, the abnormal records provide accurate data support for equipment maintenance.

[0028] In this application, the analysis process of the data analysis module includes: Clamping force analysis: Obtaining the real-time clamping force on the target blood vessel. Calculate the average clamping force per unit time. The standard deviation of the clamping force per unit time is calculated using the standard deviation formula. Set the standard value of clamping force Then through the formula Calculate the clamping force deviation rate The clamping force assessment value F is obtained by weighting the mean clamping force, standard deviation, and deviation rate with their preset weights. The formula is F=F1×f1+F2×f2+F3×f3, where f1, f2, and f3 represent the preset weights corresponding to the mean clamping force, standard deviation, and deviation rate, respectively. When the clamping force assessment value exceeds its preset safety range, it is marked as a clamping anomaly. Operational force analysis: Obtain the operational force applied to handle 5 during the vascular clamping operation. Establish real-time operational strength With clamping force The correlation model, through formula Calculate the force transmission coefficient When the force transmission coefficient exceeds the preset normal range, it is determined to be an abnormal fluctuation in the operating force; among which, These represent the change in clamping force and the change in operating force, respectively, within a preset unit of time.

Calculate the difference between the maximum and minimum real-time adaptation scores within a preset unit time to obtain the adaptation range value. 2. The adaptation fluctuation value is obtained by calculating the real-time adaptation degree within a preset unit time using the standard deviation formula. 3. The adaptation evaluation value M is obtained by weighting the real-time adaptation degree, adaptation range value, and adaptation fluctuation value. The formula is M=M1×a1+M2×a2+M3×a3, where a1, a2, and a3 are the preset weights corresponding to the real-time adaptation degree, adaptation range value, and adaptation fluctuation value, respectively. When the adaptation evaluation value exceeds its preset deviation from the adaptation range, the clamp adjustment suggestion is output. Through multi-dimensional analysis in three aspects using the data analysis module, this process achieves quantitative assessment and dynamic guidance of surgical operations, improves clamping accuracy, operational standardization, and equipment compatibility, effectively reduces surgical risks, and ensures vascular closure results.

[0029] In this application, the execution linkage control module includes a display control submodule and a device linkage submodule, as detailed below: The display control submodule receives the clamping force assessment value F output by the data analysis module, presets safety thresholds A and B (A < B, based on clinical vascular safety clamping force range calibration), and performs graded display: When F≤A, the control display device displays the first color and the "operation safe" status indicator, and simultaneously displays the basic data of vascular image adaptation and operation force transmission coefficient. When A < F ≤ B, the control display device flashes in the second color and displays a warning pop-up window that says "Operation requires caution, approaching the safety threshold," showing the clamping force trend curve, the real-time value of the operating force, and its changing trend. When F > B, the control display device displays in the third color, forcibly pops up the message "Clamping force exceeds limit, adjust operation immediately", freezes non-emergency operation buttons, and restores interface interaction after medical staff confirm and adjust the operation; The device linkage submodule obtains the blood vessel diameter.

The clamp arm mechanical linkage parameter p is calibrated through mechanical transmission tests of the clamp opening amplitude and the change in clamp arm length, i.e., the actual clamp opening amplitude value corresponding to each unit length adjustment of the clamp arm. The execution linkage control module achieves real-time early warning of operational risks and precise assistance for equipment adaptation through intuitive feedback and quantitative guidance, thereby improving the safety and standardization of surgical operations and reducing human error.
