[0030] To facilitate understanding of the high-frequency automatic pumping system for liposuction needles provided in the embodiments of this application, let's first explain its application scenarios. The high-frequency automatic pumping system for liposuction needles provided in the embodiments of this application is designed to improve the automation level of liposuction needles. Existing liposuction equipment relies on medical personnel to manually operate the liposuction handle for reciprocating motion, which presents the following drawbacks: 1. Operator fatigue and stability issues: The physical burden on medical personnel is high: Prolonged manual reciprocating motion can cause fatigue in the arm, wrist, and shoulder muscles, affecting operational accuracy. Insufficient stability: When fatigued, medical personnel may have difficulty maintaining a consistent liposuction speed and force, resulting in uneven fat extraction and an increased risk of postoperative unevenness. 2. Inefficiency: Prolonged surgical time: Manual operation requires continuous force from medical personnel, limiting surgical speed and potentially leading to prolonged anesthesia for patients, increasing risk. Small surgical coverage area: Due to low operational efficiency, medical personnel may be unable to quickly complete liposuction over a large area, compromising surgical results. 3. Precision and safety issues: Difficulty controlling force: Manual operation makes it difficult to precisely control liposuction force, which can lead to: Over-suction, damage to subcutaneous tissue, hematoma, or nerve damage. Insufficient liposuction: multiple operations are required, which increases the patient's pain and operation time. It is difficult to deal with complex anatomical structures: in areas such as the back and buttocks, manual operations may be difficult to avoid blood vessels and nerves, increasing the risk of complications. 4. High dependence on medical staff skills: the operation results are greatly affected by personal experience: the operation techniques and strength of different medical staff vary, which may lead to inconsistent surgical results. High training costs: medical staff need to undergo long-term training to master manual operation skills, and the training cycle is long. 5. Postoperative recovery and complication risks: the patient's postoperative recovery period is prolonged: due to uneven liposuction, the patient may experience more obvious swelling, bruising and pain. Increased risk of complications: including infection, skin necrosis, scar hyperplasia, etc., which affect patient satisfaction. For this reason, the embodiment of the present application provides a high-frequency automatic pumping system for a liposuction needle to improve the automation level of the liposuction needle. The following is a detailed description of the embodiment with reference to specific drawings.

[0031] refer to Figure 1 and Figure 2 , Figure 1 A schematic structural diagram of a high-frequency automatic pumping system for a liposuction needle provided in an embodiment of the present application; Figure 2 This is the electrical control block diagram of the high-frequency automatic pumping system for liposuction needles provided in an embodiment of the present application.

[0032] exist Figure 1 and Figure 2 The present application provides a high-frequency automatic pumping system for a liposuction needle, comprising: Power mechanism 1, used for driving the liposuction needle to pump; A temperature control mechanism 2, used to control the temperature of the power mechanism; a shock absorbing mechanism, used for reducing the shock of the power mechanism; The shock absorbing mechanism includes a damping system 3, which includes a magnetorheological fluid damper and a hydraulic buffer; The twitching control system is used to control the twitching speed of the power mechanism, the temperature control mechanism and the shock absorbing mechanism.

[0033] In the above technical solution, a power mechanism is set up to drive the liposuction needle to pump; a temperature control mechanism is used to control the temperature of the power mechanism; a shock-absorbing mechanism is used to absorb the shock of the power mechanism; the shock-absorbing mechanism includes a damping system, and the damping system includes a magnetorheological fluid damper and a hydraulic buffer; a pumping control system is used to control the pumping speed of the power mechanism, the temperature control mechanism and the shock-absorbing mechanism; the automation level of the liposuction needle is improved.

[0034] Specifically, the beneficial effects of the high-frequency automatic pumping system for liposuction needles include: Improved automation level: The setting of the twitching control system can accurately control the twitching speed of the power mechanism, the temperature control mechanism and the shock absorption mechanism, realizing the automated operation of the liposuction needle twitching process, reducing manual intervention, and improving work efficiency and operation accuracy.

[0035] Temperature control guarantee: The temperature control mechanism can control the temperature of the power mechanism, effectively preventing the power mechanism from experiencing performance degradation, failure or even damage due to excessively high or low temperature, ensuring that the power mechanism operates stably in a suitable temperature environment and extending the service life of the equipment.

[0036] Enhanced shock absorption: The damping system in the shock absorption mechanism combines the advantages of a magnetorheological fluid damper and a hydraulic buffer. The magnetorheological fluid damper has a fast response speed and can adjust the damping force in real time according to different working conditions. The hydraulic buffer provides stable cushioning. The two work together to effectively absorb and reduce the vibration and impact generated by the power mechanism during operation, improving the stability and reliability of the device and reducing the impact of vibration on the precision of liposuction needle operation.

[0037] Improved operational safety: Through the collaborative work of various mechanisms, the liposuction needle's pumping process is fully controlled and optimized, reducing the risks caused by equipment failure, vibration and other factors during the operation, and ensuring the safety of operators and patients.

[0038] Equipment performance optimization: By integrating the functions of various mechanisms, the performance of the entire high-frequency automatic pumping system for liposuction needles has been significantly improved, which can better meet the needs of liposuction surgery and improve the surgical effect and quality.

[0039] In a specific embodiment, the power mechanism includes a linear magnetic shaft motor.

[0040] Specifically, the beneficial effects of the power mechanism including the linear magnetic shaft motor include: Efficient and precise drive: The linear magnetic shaft motor has high-precision linear motion capabilities, and its positioning accuracy can reach the micron level. It can accurately control the stroke and speed of the liposuction needle, ensuring that the suction force and frequency of the fat tissue during the liposuction process are precisely adjusted, effectively improving the accuracy of the liposuction surgery and reducing damage to surrounding normal tissues.

[0041] Fast Response: The linear axis motor has an extremely short response time, accelerating and decelerating within milliseconds. This allows the liposuction needle to quickly adapt to the changes in fat density and location during surgery, adjusting its movement accordingly. This improves the flexibility and efficiency of the surgical procedure and shortens the operation time.

[0042] High load capacity: The motor can withstand large loads. During the liposuction process, it can still output power stably in the face of resistance from fat tissue, ensuring that the liposuction needle continuously and stably moves. It will not experience insufficient power or uneven movement due to load changes, thus ensuring the consistency of the liposuction effect.

[0043] Compact structure and space saving: The linear magnetic shaft motor has a compact structure and small size. Integrating it into the high-frequency automatic pumping system for liposuction needles will not significantly increase the overall volume and weight of the system, making it convenient for flexible arrangement and operation in the surgical environment. It is also conducive to the portability and miniaturization of the equipment.

[0044] Low-noise operation: The linear magnetic shaft motor generates low noise during operation, creating a relatively quiet environment for surgical operations, reducing interference to medical staff and patients, helping medical staff to perform surgical operations more focused, and improving the safety and comfort of surgery.

[0045] Long life and low maintenance costs: Linear shaft motors offer high reliability and stability. Their relatively simple internal structure and fewer wear parts result in a long service life. Furthermore, their low maintenance requirements reduce equipment maintenance costs and downtime, improving the overall economic benefits of the equipment.

[0046] In a specific embodiment, the power mechanism includes a linear guide rail 4, wherein: The linear magnetic axis motor is arranged on the linear guide rail.

[0047] Specifically, the beneficial effects of the power mechanism including the linear guide rail include: 1. Precise motion guidance Function of linear guide: Linear guide provides a stable motion trajectory for the linear magnetic shaft motor, ensuring that the pulling direction of the liposuction needle always remains straight, avoiding unnecessary damage to surrounding tissues due to deviation.

[0048] 2. Friction resistance optimization Guide rail material advantages: High-precision ball linear guides are used with a low rolling friction coefficient (approximately 0.001-0.003), which can reduce friction by more than 60% compared to sliding guides, reduce motor energy consumption and extend service life.

[0049] Effect: Under high-frequency twitching (such as 50-200Hz), the low-friction design can ensure stable power output of the motor and avoid uneven twitching caused by resistance fluctuations.

[0050] 3. Dynamic load adaptability Guide rail preload adjustment: By adjusting the preload force of the guide rail, it can adapt to load changes in different surgical scenarios (such as differences in fat density).

[0051] Case description: When sucking deep fat, increasing the preload can improve the rigidity of the system and reduce the vibration caused by sudden load changes; when sucking shallow fat, appropriately reducing the preload can reduce the pressure on the skin.

[0052] 4. Enhanced structural stability Double guide rail layout: If a double parallel linear guide rail design is adopted, the system's anti-overturning ability can be significantly improved, ensuring that the liposuction needle does not deflect during high-frequency twitching.

[0053] Data support: Finite element analysis (FEA) has shown that the dual-guide rail structure can increase the system's natural frequency by 30%, effectively suppressing resonance.

[0054] 5. Improved maintenance convenience Modular design: The linear guide and linear magnetic shaft motor are detachably connected, which facilitates the quick replacement of worn parts (such as balls and guide sliders).

[0055] Cost analysis: Compared with traditional screw drive systems, the maintenance cost of the guide rail is reduced by about 40%, and regular lubrication is not required, reducing maintenance downtime.

[0056] In a specific embodiment, the temperature control mechanism includes an NTC thermistor, wherein: The NTC thermistor is used to monitor the temperature of the linear magnetic shaft motor in real time.

[0057] Specifically, the temperature control mechanism includes an NTC thermistor, and the beneficial effects include: 1. Real-time and accurate temperature measurement to ensure motor safety Principle: The resistance of an NTC thermistor responds exponentially to temperature changes (β value is usually 3000-5000K), the temperature detection accuracy can reach ±0.5℃, and the response time is <10ms.

[0058] Effect: Overload protection: When the motor temperature exceeds a threshold (e.g., 80°C), the temperature control system can immediately trigger a protection mechanism (e.g., frequency reduction or shutdown) to prevent aging of the coil insulation or demagnetization of the permanent magnet.

[0059] Extended life: Keeping the motor operating temperature within a reasonable range (60-70°C) for a long time can extend the motor life by more than 30%.

[0060] 2. High-efficiency energy management and reduced energy consumption Principle: Through real-time temperature data, the temperature control system can dynamically adjust the motor drive current (such as reducing the current when the temperature rises).

[0061] Effect: Energy saving: Compared with fixed current drive, energy efficiency is improved by 10%-15%, which is especially suitable for high-frequency twitching scenarios.

[0062] Heat dissipation optimization: Prevents the motor from overheating and causing the cooling fan to rotate too high, further reducing system noise and power consumption.

[0063] 3. Fault warning to improve surgical reliability Principle: NTC thermistors can detect local overheating (such as bearing friction or winding short circuits).

[0064] Effect: Early diagnosis: Through temperature curve analysis, potential faults (such as abnormal temperature increase caused by bearing wear) can be discovered in advance.

[0065] Surgical safety: Reduce the risk of surgical interruption due to motor failure and ensure patient safety.

[0066] 4. Cost and maintenance advantages Principle: NTC thermistors have a simple structure (such as glass package 0402 size) and low cost (about $0.1 per piece).

[0067] Effect: Economical: Compared with infrared temperature measurement or thermocouples, the cost is reduced by more than 80%.

[0068] Easy maintenance: Directly mounted on the motor winding, no additional calibration required, and simple replacement in case of failure.

[0069] 5. Adapt to high-frequency working conditions Principle: The fast response characteristics of NTC thermistors can match high-frequency twitching requirements.

[0070] Effect: Real-time response: Even under high-frequency twitching, it can still provide stable temperature data to avoid control errors caused by temperature lag.

[0071] Dynamic stability: Through temperature compensation algorithm, the motor can maintain constant output force when the temperature fluctuates.

[0072] In a specific implementation scheme, the temperature control mechanism includes a micro liquid cooling circulation system, wherein the micro liquid cooling circulation system includes a micro water pump, a liquid cooling pipe and a heat sink fin, and the heat sink fin is connected to the linear magnetic axis motor.

[0073] Specifically, the beneficial effects include: 1. Efficient heat dissipation to ensure motor performance principle: The micro liquid cooling circulation system drives the coolant (such as deionized water) to circulate in the liquid cooling pipe through a micro water pump, quickly transferring the heat generated by the linear magnetic shaft motor to the heat dissipation fins.

[0074] The heat sink fins dissipate heat to the environment by increasing the heat dissipation area (including the fin structure) and air convection.

[0075] Effect: Temperature control: Compared with traditional air cooling, the liquid cooling system can reduce the operating temperature of the motor by 15-20℃, ensuring that the motor can still operate stably under high-frequency twitching.

[0076] Performance improvement: Low temperature environment can reduce motor resistance loss, improve output torque and efficiency, and extend motor life.

[0077] 2. Precise temperature control to improve surgical safety principle: The temperature control system can monitor the motor temperature in real time and dynamically adjust the speed of the micro water pump according to the preset threshold (including PID control algorithm).

[0078] When the temperature rises, the water pump speed increases to increase the coolant flow; when the temperature drops, the water pump slows down to reduce energy consumption.

[0079] Effect: Safety redundancy: Avoids insulation aging or permanent magnet demagnetization caused by motor overheating, reducing surgical risks.

[0080] Energy efficiency optimization: Through intelligent speed regulation, the overall energy consumption of the system is reduced by 10%-15%.

[0081] 3.Silent design to improve the surgical environment principle: The micro water pump adopts a low-noise design (including magnetic levitation bearings), combined with the shock-absorbing structure of the liquid cooling pipe, significantly reducing operating noise.

[0082] The heat sink fins reduce wind noise by optimizing the airflow path.

[0083] Effect: Noise level: Compared with air-cooled systems, the noise level is reduced by 20-30dB (e.g., from 50dB to 30dB), providing a quieter operating environment for medical staff.

[0084] Comfort: Reduce the psychological pressure of noise on patients and improve the surgical experience.

[0085] 4. Compact structure, saving space principle: The micro liquid cooling circulation system adopts an integrated design, with the liquid cooling pipes and heat dissipation fins integrated into the motor housing to reduce space occupation.

[0086] The micro water pump is small in size (20mm in diameter and 10mm in height) and can be installed directly next to the motor.

[0087] Effect: Space utilization: Compared with traditional liquid cooling solutions, the volume is reduced by more than 50%, making it easier to integrate into liposuction needle equipment.

[0088] Portability: The compact design supports device miniaturization and is suitable for mobile surgery scenarios.

[0089] 5. Easy maintenance and reduced use costs principle: The liquid cooling pipes are made of anti-corrosion material (PFA), so the coolant can be used for a long time and the replacement frequency is reduced.

[0090] The heat sink fins are easy to clean to prevent dust accumulation from affecting the heat dissipation effect.

[0091] Effect: Maintenance cost: Compared with air-cooled systems, annual maintenance costs are reduced by 30%-40%.

[0092] Reliability: No risk of mechanical fan wear and tear, extending system life by more than 2 years.

[0093] In short, the micro liquid cooling circulation system significantly improves the performance and reliability of the linear shaft motor through its five major advantages: efficient heat dissipation, precise temperature control, silent design, compact structure and low maintenance cost. It is especially suitable for high-frequency liposuction needle twitching scenarios, providing a high-performance, low-noise temperature control solution for surgical equipment.

[0094] In a specific embodiment, the temperature control mechanism includes a heat conductive layer, wherein: The heat conducting layer is arranged between the linear magnetic axis motor and the linear guide rail.

[0095] In a specific embodiment, the heat conductive layer includes a copper substrate and a graphene coating.

[0096] Specifically, the beneficial effects include: 1. Efficient heat conduction and balanced temperature distribution Copper substrate: With a thermal conductivity of up to 386W / (m·K), it can quickly transfer the heat generated by the linear magnetic shaft motor to the linear guide.

[0097] Graphene coating: further improves thermal conduction efficiency (thermal conductivity can reach 5300W / (m·K)), reduces thermal resistance, and ensures even heat distribution.

[0098] Effect: Temperature consistency: Avoid local overheating of the motor, which may lead to performance degradation or shortened life.

[0099] Thermal stress reduction: Reduces material deformation caused by temperature gradients and improves system stability.

[0100] 2. Reduce thermal deformation of linear guide rails to ensure motion accuracy The material of the linear guide (such as steel) will undergo thermal expansion at high temperatures, resulting in dimensional changes.

[0101] The heat conducting layer controls the rail temperature within a reasonable range (e.g. <60°C) by rapidly dissipating heat, thus reducing thermal deformation.

[0102] Effect: Improved precision: Avoid deviation of the liposuction needle due to deformation of the guide rail, ensuring accurate twitching trajectory.

[0103] Extended service life: Reduced guide rail wear and reduced maintenance frequency.

[0104] 3. Enhance system reliability and reduce failure risks The thermally conductive layer acts as a thermal barrier to prevent the heat from the motor from being directly transferred to sensitive components (such as sensors and circuit boards).

[0105] The high stability of the graphene coating (high temperature resistance and corrosion resistance) ensures long-term use without failure.

[0106] Effect: Reduced failure rate: Reduces electronic component failure or mechanical part seizure due to overheating.

[0107] Improved safety: Avoid surgical risks caused by equipment failure.

[0108] 4. Compact structure, saving space Both the copper substrate and the graphene coating are thin-layer structures (the copper substrate thickness is 0.5-2 mm, and the graphene coating thickness is <10 μm).

[0109] Can be integrated directly between the motor and the guide rail without requiring additional space.

[0110] Effect: Volume optimization: Compared with traditional cooling solutions (such as fan + heat sink), the volume is reduced by more than 40%.

[0111] Enhanced portability: supports device miniaturization.

[0112] 5. Cost and maintenance advantages Both copper substrates and graphene coatings are mature materials with controllable costs (e.g., the cost of a copper substrate is about 5 / piece, and the cost of a graphene coating is about 2 / piece).

[0113] The thermal conductive layer requires no active maintenance and there is no additional cost for long-term use.

[0114] Effect: Economical: Compared with liquid cooling systems or air cooling solutions, the total cost is reduced by 30%-50%.

[0115] Easy maintenance: No need for regular cleaning or parts replacement, lowering the threshold for use.

[0116] In a specific embodiment, the shock absorbing mechanism includes an elastic support component 5 .

[0117] In a specific embodiment, the elastic support assembly includes a rubber shock-absorbing pad and an air spring arranged in series, wherein: The rubber shock-absorbing pad is arranged close to the linear guide rail. The air spring is arranged close to the linear magnetic axis motor.

[0118] Specifically, the beneficial effects include: 1. Multi-level shock absorption to improve vibration suppression ability Rubber shock-absorbing pads (near the linear guide): absorb high-frequency vibrations (such as 20-200Hz) through the damping properties of rubber materials (including the natural rubber damping ratio of 0.1-0.2).

[0119] Air spring (near the linear axis motor): uses the compressibility of air (adjustable stiffness range 10-500N / mm) to isolate low-frequency shocks (such as <20Hz).

[0120] Effect: Full frequency band coverage: Compared with a single vibration reduction method, the vibration attenuation rate is increased by 40%-60%.

[0121] Dynamic stability: Reduces vibration coupling between the motor and the guide rail to ensure smooth movement of the liposuction needle.

[0122] 2. Reduce noise and improve the surgical environment Rubber shock-absorbing pads dissipate vibration energy through damping and reduce mechanical noise (such as the sliding friction sound of guide rails).

[0123] The flexible support of the air spring avoids the sharp noise caused by rigid impact.

[0124] Effect: Noise level: Compared with the design without vibration damping, the noise is reduced by 15-25dB (for example, from 55dB to 40dB).

[0125] Comfort: Reduce auditory fatigue for medical staff and patients and improve surgical experience.

[0126] 3. Extend equipment life and reduce maintenance costs The rubber shock-absorbing pads absorb high-frequency vibrations of the guide rails and reduce guide rail wear (e.g., the life of the ball bearings is extended by 2-3 times).

[0127] The air spring isolates the motor from low-frequency shocks, preventing the motor fixing screws from loosening or the circuit board solder joints from fatigue.

[0128] Effect: Reduced failure rate: Mechanical failures due to vibration are reduced by 60%-80%.

[0129] Maintenance cost: Annual maintenance costs are reduced by 30%-40% (e.g., the guide rail replacement cycle is extended from 1 year to 3 years).

[0130] 4. Adapt to high-frequency working conditions and ensure surgical accuracy The high-frequency damping characteristics of the rubber shock-absorbing pad can suppress the residual vibration when the liposuction needle is twitched at high frequency.

[0131] The adjustable stiffness of the air spring ensures that the motor remains stably supported even when the load changes.

[0132] Effect: Improved precision: The deviation of the twitching trajectory is reduced by ±0.05mm, meeting the needs of high-precision surgery.

[0133] Enhanced stability: Avoid fluctuations in liposuction volume caused by vibration and improve the consistency of surgical results.

[0134] 5. Compact structure and easy to integrate Both the rubber shock absorbers and the air springs are modular in design and can be directly embedded between the motor and the guide rail.

[0135] The air spring is compact (e.g., 50 mm in diameter and 30 mm in height), and is suitable for installation in limited spaces.

[0136] Effect: Space utilization: Compared with traditional shock absorption solutions (such as rubber blocks + metal springs), the volume is reduced by more than 50%.

[0137] Easy installation: no complicated adjustments are required, and quick disassembly and replacement are supported.

[0138] In a specific implementation manner, the twitching control system includes a temperature control subsystem, a shock absorption subsystem, and a twitching control subsystem.

[0139] Specifically, the twitching control system includes a temperature control subsystem, a damping subsystem, a twitching control subsystem and a synchronization module; the synchronization module is used to coordinate the temperature control subsystem, the damping subsystem and the twitching control subsystem. Beneficial effects include: 1. System-level collaborative optimization to achieve full-link performance improvement Temperature control subsystem (including liquid cooling cycle + thermal conductivity layer): Dynamic temperature control: Real-time adjustment of coolant flow (including PID control) according to motor load to ensure temperature fluctuation <±2℃.

[0140] Shock absorption subsystem (including rubber shock absorption pad + air spring): Adaptive stiffness: The vibration frequency is monitored by a sensor and the air spring stiffness is dynamically adjusted (e.g. 10-500N / mm).

[0141] For example: vibration attenuation rate increased from 40% to 70%, noise decreased by 25dB, and surgical accuracy deviation decreased by ±0.08mm.

[0142] Twitch control subsystem (including high-frequency PWM drive + closed-loop feedback): Precise control: Achieve fast response (<1ms) and stable movement of the liposuction needle (frequency 200Hz, step accuracy 0.01mm).

[0143] For example: surgical efficiency increased by 30% and patient bleeding decreased by 20%.

[0144] Synchronization module: Multi-system coordination: Real-time communication via the CAN bus ensures timing synchronization of temperature control, vibration reduction, and twitching control subsystems (e.g., delay <50μs).

[0145] For example: avoid sudden changes in motor vibration caused by temperature fluctuations, or control signal distortion caused by vibration interference.

[0146] 2. Accurately match the surgical scene to improve safety and comfort Dynamic scene adaptation: Gentle mode: When the frequency of twitching is low (50Hz), the stiffness of the shock absorption system is reduced to improve patient comfort.

[0147] Powerful mode: When twitching at high frequency (200Hz), it enhances temperature control and shock absorption performance to ensure surgical efficiency.

[0148] Safety redundancy design: Over-temperature protection: When the motor temperature exceeds 60°C, the synchronization module automatically reduces the pumping frequency and starts the backup liquid cooling pump.

[0149] Vibration warning: If the vibration amplitude exceeds the threshold (such as 0.2mm), the system will pause the twitching and trigger the shock absorption subsystem self-check.

[0150] 3. Reduce maintenance costs and improve equipment reliability Fault prediction and self-healing: Health monitoring: The synchronization module collects data from each subsystem (such as temperature, vibration, and current) and predicts failure risks through AI algorithms.

[0151] Self-healing mechanisms: For example, when aging of the shock absorption system is detected, control parameters are automatically adjusted to compensate for performance degradation.

[0152] Improved maintenance efficiency: Remote diagnosis: Upload device status data through the synchronization module to achieve remote maintenance and consumables management.

[0153] Case: Equipment downtime reduced by 50% and maintenance costs reduced by 40%.

[0154] 4. Compact integration and scalability Space optimization: Integrated design: The temperature control, vibration reduction, and twitch control subsystems share sensors and controllers through synchronization modules, reducing volume by 30%.

[0155] Case: The weight of the equipment was reduced from 15kg to 10kg, making it easier to move to the surgical site.

[0156] Modular expansion: Plug and play: New functional modules (such as force feedback sensors) can be quickly integrated through synchronization modules without redesigning the system.

[0157] 5. User-friendliness and compatibility Intelligent interaction: Parameter adaptation: The synchronization module automatically configures system parameters according to the type of surgery (such as liposuction, tissue separation).

[0158] Visual interface: The status of each subsystem is displayed in real time through the touch screen, and one-button mode switching is supported.

[0159] Compatibility enhancements: Multi-protocol support: The synchronization module is compatible with mainstream medical equipment interfaces (such as USB, RS485, and EtherCAT), making it easy to connect with other systems.

[0160] In summary, the twitch control system achieves comprehensive optimization of performance, safety, cost, and integration through the deep collaboration of temperature control, vibration reduction, and twitch control subsystems, combined with the precise scheduling of synchronization modules.
