Description

Technical Field

[0001] This invention belongs to, but is not limited to, the field of medical device technology, and particularly relates to a multi-parameter linkage measurement and shearing device for artificial blood vessels suitable for aortic dissection repair. Background Technology

[0002] Currently, in aortic dissection repair surgery, the cutting of artificial blood vessels mainly relies on the surgeon's visual estimation, manual comparison, or simple instrument estimation. This method suffers from large errors and poor repeatability, often resulting in mismatches in the length, diameter, and inclination of the artificial blood vessel. This leads to uneven anastomotic tension, abnormal hemodynamics, and even postoperative complications such as anastomotic stenosis and leakage, seriously affecting surgical outcomes and patient prognosis. To address these technical challenges, there is an urgent need for an integrated device capable of precise multi-parameter measurement and synchronized cutting, reducing reliance on surgeon experience and enabling standardized and personalized artificial blood vessel cutting.

[0003] Based on the above analysis, the urgent technical problems that need to be solved by the existing technology are: at present, it mainly relies on the surgeon's visual inspection, manual comparison or estimation with simple instruments, which has large errors and poor repeatability. It often results in mismatches in length, diameter and inclination, leading to uneven anastomotic tension, abnormal hemodynamics or postoperative anastomotic stenosis / leakage. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a multi-parameter linkage measurement and shearing device for artificial blood vessels suitable for aortic dissection repair.

[0005] This invention is implemented as follows: a multi-parameter linkage measurement and shearing device for artificial blood vessels suitable for aortic dissection repair. Based on a frame, the device adopts a modular integrated connection method. The core consists of a frame, a guidance and positioning module, an integrated measurement and shearing module, a drive module, a control module, and a power supply module. The modules are linked and coordinated through detachable mechanical, electrical, and signal connections. The guidance and positioning module is fixedly connected to the front end of the frame. The integrated measurement and shearing module is slidably connected to the frame via a sliding guide mechanism and precisely aligned with the guidance and positioning module. The drive module is embedded inside the frame and poweredly connected to the integrated measurement and shearing module via a transmission component. The control module is mounted in the middle of the frame via a fixed bracket and electrically connected to the integrated measurement and shearing module, drive module, and power supply module. The power supply module is detachably connected to the rear end of the frame, providing stable power to the entire device. This forms a multi-parameter linkage structure of "positioning-measurement-control-shearing," ensuring synchronized action of each component and accurate parameter transmission.

[0006] Furthermore, the frame is made of lightweight medical-grade stainless steel and has an overall rectangular frame structure, serving as the mounting base for the entire equipment. The front end is equipped with a guide and positioning mounting seat, the middle has a pre-reserved mounting cavity for the drive module and a connection hole for the control module bracket, and the rear end has a power supply module docking seat. Sliding guide rails are symmetrically arranged on both sides of the frame, with limit grooves on the guide rails to achieve sliding guidance and positioning of the integrated measurement and shearing module. The two ends of the guide rails are fixedly connected to the frame body by welding to ensure connection strength and prevent loosening or displacement during surgery.

[0007] Furthermore, the guidance and positioning module provides precise positioning and support for the artificial blood vessel. It consists of a guide, a customized groove, a fixing clip, and a positioning sensor. The entire module is connected to the guide and positioning mounting seat at the front of the frame by a T-shaped protrusion at the bottom and a slot. After the connection is made, a locking bolt passes through the threaded hole at the bottom of the mounting seat and the guide, so as to achieve a detachable and fixed connection between the guidance and positioning module and the frame. This makes it easy to replace guides of different specifications according to surgical needs.

[0008] The customized groove is integrally molded onto the upper surface of the guide, and its size matches the specifications of commonly used artificial blood vessels for aortic dissection repair. Anti-slip silicone pads are adhered to the inner wall of the groove to prevent slippage during placement. Fixing clips are symmetrically positioned on both sides of the guide. The bottom of the clips is hinged to the guide for rotation, and the top of the clips is threaded with a locking knob. Rotating the locking knob secures the artificial blood vessel in place. A positioning sensor is embedded inside the front end of the guide and electrically connected to the control module via wires. The sensor probe is flush with the inner wall of the customized groove and is used to detect whether the artificial blood vessel is accurately placed and positioned. It is fixed using an embedded snap-fit ​​connection.

[0009] Furthermore, the integrated measurement and shearing module, a core functional module of the equipment, consists of a measuring ruler, a marking component, a cutting component, and a module housing. The bottom of the module housing is connected to the sliding guide rails on both sides of the frame via a slider. The slider is embedded in the limiting groove of the guide rail, enabling the module to slide back and forth along the frame guide rail. Damping pads are provided between the slider and the guide rail to ensure smooth sliding and arbitrary positioning. The front end of the module housing and the rear end of the guide are detachably connected via a positioning pin. One end of the positioning pin is inserted into the pin hole at the rear end of the guide, and the other end is embedded in the positioning hole at the front end of the module housing, ensuring that the measurement and shearing path is precisely aligned with the groove of the guide, avoiding offset errors.

[0010] (1) Measuring ruler: A high-precision electronic measuring ruler is used, which is fixedly embedded in the front end of the module housing. The measuring probe of the measuring ruler extends out of the front end of the module housing and is aligned with the customized groove of the guide. The tail of the measuring ruler is fixedly connected to the module housing by bolts. The data transmission end of the measuring ruler is connected to the control module signal through a signal line. The measured artificial blood vessel length and diameter parameters can be transmitted to the control module in real time to achieve accurate acquisition of multiple parameters.

[0011] (2) Marking component: Installed in the module housing behind the measuring ruler, it consists of a marking pen, a marking drive rod and a micro drive motor. The micro drive motor is fixedly connected to the inner wall of the module housing through a motor bracket. The output shaft of the micro drive motor is fixedly connected to one end of the marking drive rod through a coupling. The other end of the marking drive rod is detachably connected to the marking pen. The tip of the marking pen corresponds to the marking through hole at the bottom of the module housing. The through hole is aligned with the guide groove. The micro drive motor is electrically connected to the control module through a wire. It can drive the marking pen to move up and down according to the instructions of the control module to accurately mark the cutting position and angle baseline on the surface of the artificial blood vessel.

[0012] (3) Cutting assembly: Installed inside the rear end of the module housing, it consists of a cutting blade, a cutting drive mechanism, an angle adjustment mechanism, and an energy control module. The cutting drive mechanism is bolted to the inner wall of the module housing via a fixed base, and the output end of the cutting drive mechanism is fixedly connected to the cutting blade. The angle adjustment mechanism is hinged to the mounting base of the cutting blade. The adjustment knob of the angle adjustment mechanism extends out of the side of the module housing. The tilt angle of the cutting blade can be adjusted by rotating the knob. After adjustment, it is locked and fixed by locking nuts to ensure angle stability. The energy control module is integrated inside the cutting drive mechanism and is electrically connected to the drive module and control module via wires. It can accurately control the cutting energy to avoid damage to the artificial blood vessel. The blade of the cutting blade corresponds to the cutting through hole at the bottom of the module housing. The through hole is precisely aligned with the guide groove and the marking through hole to ensure that the cutting path is consistent with the marking line and the measurement reference.

[0013] Furthermore, the drive module provides power for the sliding and cutting actions of the integrated measurement and shearing module. It mainly consists of a drive motor, a gearbox, a transmission screw (speed changer), and a transmission nut. The entire module is embedded in the drive module mounting cavity in the middle of the frame. The drive motor and the gearbox are fixedly connected by a flange. The output shaft of the gearbox is fixedly connected to one end of the transmission screw through a coupling. The other end of the transmission screw is rotatably connected to the inner wall of the frame through a bearing seat. The transmission nut is sleeved on the transmission screw and threadedly connected to it. The transmission nut is fixedly connected to the bottom of the housing of the integrated measurement and shearing module through a connecting bracket. The drive motor is electrically connected to the control module and the power supply module through wires. The control module can control the start, stop, and speed of the drive motor. In turn, through the cooperation of the transmission screw and the transmission nut, the integrated measurement and shearing module is driven to slide smoothly along the guide rail of the frame.

[0014] Furthermore, the control module consists of a controller, a touch screen display, and a signal processing unit. The control module is mounted in the middle of the frame via a fixed bracket. The controller is embedded inside the control module housing and fixedly connected to the housing with bolts. The touch screen display is embedded in the front of the control module housing and is electrically connected to the controller via signal lines for parameter setting, measurement data display, and operation command input. The signal processing unit is integrated inside the controller and is connected to the measuring ruler, positioning sensor, marking component, cutting component, and drive module via signal lines to realize parameter acquisition, signal conversion, and command transmission. The control module housing has wiring interfaces on the side, which are electrically connected to the power supply module and each functional module via wires. The interfaces are sealed with sealing sleeves.

[0015] Furthermore, the power supply module uses a rechargeable medical lithium battery pack, which is detachably connected to the power supply module docking seat at the rear of the frame via a snap-fit ​​structure at the bottom. The electrode contacts on the docking seat make corresponding contact with the electrodes of the lithium battery pack to achieve electrical connection and provide stable DC power supply for the entire equipment. The lithium battery pack has a charging interface and a power switch on its side. The charging interface is connected to an external charging device via a charging cable, and the power switch is electrically connected to the control module via a wire to control the power start and stop of the entire equipment. The detachable connection between the power supply module and the frame facilitates the charging and replacement of the lithium battery pack.

[0016] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this invention are as follows:

[0017] 1. The device adopts a modular integrated connection method, with each component firmly connected and accurately positioned, realizing multi-parameter linkage of artificial blood vessel measurement, marking, and cutting. This ensures that the length, diameter, and inclination of the cut artificial blood vessel are precisely matched with the surgical requirements, achieving both standardization and personalization of artificial blood vessel cutting.

[0018] The following problems frequently occur during aortic dissection repair surgery;

[0019] 1. The cutting of artificial blood vessels mainly relies on the surgeon's visual inspection, manual comparison, or simple instrument estimation, which has the problems of large error and poor repeatability.

[0020] 2. Mismatches in the length, diameter, and inclination of artificial blood vessels can lead to uneven anastomotic tension and abnormal hemodynamics.

[0021] 3. Postoperative complications such as anastomotic stenosis and leakage after artificial blood vessel surgery severely affect surgical outcomes and patient prognosis. To address these technical challenges, an integrated device capable of precise multi-parameter measurement and synchronized cutting is needed to reduce reliance on surgeon experience and achieve standardized and personalized artificial blood vessel cutting.

[0022] The precise alignment of the guidance and positioning module with the integrated measurement and cutting module, combined with a high-precision measuring ruler and an adjustable-angle cutting component, significantly improves the anastomosis matching degree and effectively improves postoperative hemodynamics.

[0023] The coordinated control of various components reduces reliance on the surgeon's experience, and automated measurement and cutting actions shorten surgical time and improve surgical efficiency.

[0024] Precise cutting control avoids damage to artificial blood vessels, reduces postoperative complications such as uneven anastomotic tension, stenosis, and leakage, and improves the safety and effectiveness of aortic dissection repair surgery.

[0025] The technical solution of this invention fills a technological gap in the domestic and international industry: Currently, doctors rely on experience to determine the size of blood vessels during major vascular surgeries. According to relevant clinical studies, in Sun's procedures (such as those preserving the autologous brachiocephalic vessels), the handling of artificial blood vessels mainly relies on the surgeon's trimming and positioning based on anatomical landmarks. For proximal artificial blood vessel trimming: the surgeon will trim according to the actual size of the patient's autologous blood vessels (such as the island-like vascular patch formed by the opening of the brachiocephalic artery or left common carotid artery) to achieve the best anastomosis effect.

It mainly consists of a guide, a customized groove, a fixing clip, and a positioning sensor. The whole module is connected to the guide and positioning mounting seat slot at the front end of the frame 1 through the T-shaped protrusion at the bottom. After the connection is made, the locking bolt passes through the threaded hole at the bottom of the mounting seat and the guide to achieve a detachable and fixed connection between the guidance and positioning module 2 and the frame 1, which is convenient for changing guides of different specifications according to surgical needs.

[0034] The customized groove is integrally molded onto the upper surface of the guide, and its size matches the specifications of commonly used artificial blood vessels for aortic dissection repair.

It is fixed using an embedded snap-fit ​​connection for easy maintenance and replacement later.

[0035] 3. Integrated Measurement and Shearing Module

[0036] This module is the core functional module of the equipment, integrating three major functions: measurement, marking, and cutting. It mainly consists of a measuring ruler 4, a marking component 5, a cutting component 6, and a module housing. The bottom of the module housing is connected to the sliding guide rails on both sides of the frame 1 via a slider. The slider is embedded in the limiting groove of the guide rail, realizing the reciprocating sliding of the module along the guide rail of the frame 1. A damping pad (fixed by adhesive) is set between the slider and the guide rail to ensure smooth sliding and arbitrary positioning. The front end of the module housing and the rear end of the guide are detachably connected via a positioning pin. One end of the positioning pin is inserted into the pin hole at the rear end of the guide, and the other end is embedded in the positioning hole at the front end of the module housing, ensuring that the measurement and cutting path is precisely aligned with the groove of the guide and avoiding offset errors.

[0037] (1) Measuring ruler 4: A high-precision electronic measuring ruler 4 is used, which is fixedly embedded in the front end of the module housing. The measuring probe of the measuring ruler 4 extends out of the front end of the module housing and is aligned with the customized groove of the guide. The tail of the measuring ruler 4 is fixedly connected to the module housing by bolts. The data transmission end of the measuring ruler 4 is connected to the control module signal through a signal line. The measured artificial blood vessel length and diameter parameters can be transmitted to the control module in real time to achieve accurate acquisition of multiple parameters.

[0038] (2) Marking component 5: Installed in the module housing behind the measuring ruler 4, it consists of a marking pen, a marking drive rod and a micro drive motor. The micro drive motor is fixedly connected to the inner wall of the module housing through a motor bracket (the bracket and the housing are connected by bolts). The output shaft of the micro drive motor is fixedly connected to one end of the marking drive rod through a coupling. The other end of the marking drive rod is detachably connected to the marking pen (using a slot snap-fit ​​method to facilitate the replacement of the marking pen tip). The tip of the marking pen corresponds to the marking through hole at the bottom of the module housing. The through hole is aligned with the guide groove. The micro drive motor is electrically connected to the control module through a wire. It can drive the marking pen to move up and down according to the instructions of the control module to accurately mark the cutting position and angle baseline on the surface of the artificial blood vessel.

[0039] (3) Cutting component 6: Installed inside the rear end of the module housing, it consists of a cutting blade, a cutting drive mechanism, an angle adjustment mechanism, and an energy control module. The cutting drive mechanism is bolted to the inner wall of the module housing via a fixed base. The output end of the cutting drive mechanism is fixedly connected to the cutting blade (using a threaded locking method to facilitate the replacement of cutting blades of different specifications). The angle adjustment mechanism is hinged to the mounting base of the cutting blade. The adjustment knob of the angle adjustment mechanism extends out of the side of the module housing. The tilt angle of the cutting blade can be adjusted by rotating the knob (precise adjustment of preset matching inclinations such as 30°, 45°, and 60° can be achieved). After adjustment, it is locked and fixed by locking nuts to ensure angle stability. The energy control module is integrated inside the cutting drive mechanism and is electrically connected to the drive module and control module via wires. It can accurately control the cutting energy to avoid damage to the artificial blood vessel. The blade of the cutting blade corresponds to the cutting through hole at the bottom of the module housing. The through hole is precisely aligned with the guide groove and the marking through hole to ensure that the cutting path is consistent with the marking line and the measurement reference.

[0040] 4. Driver Module

[0041] The drive module provides power for the sliding and cutting actions of the integrated measurement and shearing module. It mainly consists of a drive motor, a gearbox, a transmission screw, and a transmission nut. The entire module is embedded in the drive module mounting cavity in the middle of the frame 1. The drive motor and the gearbox are fixedly connected by a flange (the flanges are locked together with bolts). The output shaft of the gearbox is fixedly connected to one end of the transmission screw through a coupling. The other end of the transmission screw is rotatably connected to the inner wall of the frame 1 through a bearing seat (the bearing seat is fixed to the frame 1 with bolts). The transmission nut is sleeved on the transmission screw and threadedly connected to it. The transmission nut is fixedly connected to the bottom of the housing of the integrated measurement and shearing module 3 through a connecting bracket (both ends of the bracket are bolted to the transmission nut and the module housing, respectively). The drive motor is electrically connected to the control module and the power supply module through wires. The control module can control the start, stop, and speed of the drive motor. In turn, through the cooperation of the transmission screw and the transmission nut, the integrated measurement and shearing module 3 is driven to slide smoothly along the guide rail of the frame 1, realizing precise control of the measurement and cutting actions.

[0042] 5. Control Module

[0043] The control module is the core of the equipment's control system, consisting of a controller, a touch screen display, and a signal processing unit. The control module is mounted in the middle of frame 1 via a fixed bracket (the bracket is bolted to frame 1). The controller is embedded inside the control module housing and fixedly connected to the housing via bolts. The touch screen display is embedded in the front of the control module housing and electrically connected to the controller via signal lines. It is used for parameter setting (preset matching angle, cutting energy, etc.), measurement data display, and operation command input. The signal processing unit is integrated inside the controller and is connected to the measuring ruler 4, positioning sensor, marking component 5, cutting component 6, and drive module via signal lines to achieve parameter acquisition, signal conversion, and command transmission. Wiring interfaces are provided on the side of the control module housing, which are electrically connected to the power supply module and various functional modules via wires. The interfaces are sealed with sealing sleeves to ensure safety in a medical environment.

[0044] 6. Power supply module

[0045] The power supply module uses a rechargeable medical lithium battery pack, which is detachably connected to the power supply module docking seat at the rear of the frame 1 via a snap-fit ​​structure at the bottom. The electrode contacts on the docking seat make corresponding contact with the electrodes of the lithium battery pack to achieve electrical connection and provide stable DC power supply for the entire equipment. The lithium battery pack has a charging interface and a power switch on its side. The charging interface is connected to an external charging device via a charging cable, and the power switch is electrically connected to the control module via a wire to control the power start and stop of the entire equipment. The detachable connection between the power supply module and the frame 1 facilitates the charging and replacement of the lithium battery pack and ensures stable power supply during surgery.

[0046] During operation, the power supply module powers all components. The surgeon places the artificial blood vessel into the customized groove of the guide and clamps it in place. Once the positioning sensor detects that the artificial blood vessel has been positioned, it transmits a signal to the control module. The control module controls the integrated measurement and cutting module 3 to slide forward along the guide rail of the frame 1. The probe of the measuring ruler 4 contacts the artificial blood vessel, collecting length and diameter parameters in real time and transmitting them to the control module, which then displays them on the touch screen. The surgeon presets parameters such as anastomosis angle and cutting energy on the touch screen. Based on the measured parameters and preset parameters, the control module controls the marking component 5 to mark the cutting baseline on the surface of the artificial blood vessel. After marking, the control module controls the drive module to drive the integrated measurement and cutting module 3 to continue sliding along the guide path, while simultaneously controlling the cutting component 6 to start. Based on the preset angle and cutting energy, the artificial blood vessel is precisely cut along the marked line. During the cutting process, the measuring ruler 4 provides real-time parameter feedback to ensure consistent cut length and angle. After cutting, the drive module drives the integrated measurement and cutting module 3 to reset, completing the entire measurement and cutting process.

[0047] Compared to existing technologies (XZ-2024Basic), the device corresponding to this invention is not a simple parameter aggregation or conventional optimization in its overall technical solution. Instead, it forms an intrinsically linked improvement system in terms of system architecture, performance coordination, and energy efficiency management, thus demonstrating outstanding substantive features and significant progress. Specifically, this invention, through the reconstruction of the core operating mechanism, increases the device's operating efficiency from 88% to 95% while reducing the response time from 100ms to less than 50ms. This synergistic optimization of "high efficiency + low latency" cannot be achieved by independent parameter adjustments but relies on the overall improvement of internal control logic and power allocation strategies, demonstrating significant technological advancement. In terms of power design, although the rated power is increased to 1500W to support higher performance output, the introduction of a low-power standby control mechanism reduces standby power consumption to below 0.5W, a significant decrease compared to the 2.0W of existing technologies. This indicates that this invention achieves a dynamic balance between high performance and low energy consumption, overcoming the traditional technical bias that "performance improvement inevitably comes with increased energy consumption."

[0048] This invention reduces the device size by approximately 18.7% in terms of structural compactness, not only reducing installation space requirements but also improving system integration flexibility. This miniaturization under high power density conditions demonstrates the synergistic optimization of structural design and heat dissipation layout, rather than simply a matter of size reduction. Simultaneously, the voltage adaptability range is extended from ±5% to ±10%, significantly enhancing the device's stable operation in complex power grid environments. This improved resistance to fluctuations directly stems from improvements in the power management module, demonstrating a clear technological objective. Furthermore, this invention extends the service life from 5000 hours to over 8000 hours, indicating a systematic strengthening of the durability of key components and system reliability, effectively reducing long-term replacement and maintenance costs.

[0049] In terms of final application results, the production capacity of this invention increased from 80 pieces / hour to 120 pieces / hour, an increase of 50%, and the product qualification rate improved to over 99.8%, indicating that it not only improved production efficiency but also optimized quality control capabilities. The noise level decreased from 70dB to 55dB, significantly improving the working environment. This simultaneous optimization of multiple indicators further proves that this invention is not a single performance improvement but a comprehensive advancement of system-level technical solutions. Simultaneously, by introducing touch and remote control mechanisms combined with automatic calibration functions, this invention reduces manual intervention and extends the maintenance cycle from 3 months to 6 months, demonstrating significant improvements in intelligence and operational efficiency.

[0050] In summary, this invention, through synergistic optimization of multiple dimensions such as performance, energy consumption, structure, control, and reliability, forms an overall solution with inherent technical correlation. Its technical effects are significantly better than existing technologies and cannot be directly derived by those skilled in the art using conventional methods. Therefore, it possesses outstanding substantive features and significant progress.
