Therefore, this application provides a high-frequency automatic aspiration system for liposuction needles to improve the automation level of liposuction needles. The following detailed description, in conjunction with specific accompanying drawings, illustrates this system.

[0050] exist Figure 1 and Figure 2 This application provides a high-frequency automatic aspiration system for liposuction needles, comprising:

[0051] Power mechanism 1 is used to drive the liposuction needle to move.

[0052] Temperature control mechanism 2 is used to control the temperature of the power mechanism;

[0053] A shock-absorbing mechanism is used to dampen the vibration of the power mechanism;

[0054] The shock absorption mechanism includes a damping system 3, which includes a magnetorheological fluid damper and a hydraulic buffer.

[0055] The pumping control system is used to control the pumping speed of the power mechanism, the temperature control mechanism, and the shock absorption mechanism.

[0057] Specifically, the beneficial effects of the high-frequency automatic aspiration system for liposuction needles include:

[0058] Enhanced automation: The suction control system allows for precise control of the suction speed of the power mechanism, the temperature control mechanism, and the shock absorption mechanism, thus automating the liposuction cannula suction process, reducing manual intervention, and improving work efficiency and operational accuracy.

[0059] Temperature control guarantee: The temperature control mechanism can control the temperature of the power mechanism, effectively preventing performance degradation, malfunction or even damage caused by excessively high or low temperatures, ensuring stable operation of the power mechanism in a suitable temperature environment, and extending the service life of the equipment.

[0060] Enhanced vibration damping: The damping system in the vibration damping mechanism combines the advantages of magnetorheological fluid dampers and hydraulic buffers. 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 a stable buffering effect. The two work together to effectively absorb and reduce the vibration and impact generated by the power mechanism during operation, improve the stability and reliability of the equipment, and reduce the impact of vibration on the operating accuracy of the liposuction needle.

[0061] Improved operational safety: Through the collaborative work of various institutions, the liposuction cannula extraction 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.

[0062] Equipment performance optimization: By integrating the functions of each component, the performance of the entire liposuction cannula high-frequency automatic aspiration system has been significantly improved, which can better meet the needs of liposuction surgery and improve the surgical effect and quality.

[0063] In one possible implementation, the power mechanism includes a linear magnetic shaft motor.

[0064] Specifically, the advantages of the power mechanism including a linear magnetic shaft motor include:

[0065] Highly efficient and precise drive: The linear magnetic shaft motor has high-precision linear motion capability, with a positioning accuracy down to the micrometer level. It can precisely control the stroke and speed of the liposuction cannula, ensuring that the suction force and frequency of fat tissue can be precisely adjusted during liposuction, effectively improving the accuracy of liposuction surgery and reducing damage to surrounding normal tissues.

[0066] Rapid response characteristics: The linear magnetic shaft motor has an extremely short response time, completing acceleration and deceleration actions within milliseconds. This allows the liposuction cannula to quickly adapt to changes in different areas and fat densities during the procedure, adjusting the suction state in a timely manner, improving the flexibility and efficiency of the surgical operation, and shortening the operation time.

[0067] High load capacity: This motor can withstand a large load. During liposuction, it can still output power stably despite the resistance of fat tissue, ensuring that the liposuction cannula can perform continuous and stable suction without insufficient power or uneven suction due to load changes, thus ensuring consistent liposuction results.

[0068] Compact and space-saving: The linear magnetic shaft motor has a compact structure and small size. Integrating it into the high-frequency automatic aspiration system for liposuction needles will not significantly increase the overall size and weight of the system. It is easy to arrange and operate flexibly in the surgical environment, and it also contributes to the portability and miniaturization of the equipment.

[0069] Low-noise operation: The linear magnetic shaft motor generates low noise during operation, creating a relatively quiet environment for surgical procedures, reducing interference with medical staff and patients, helping medical staff to focus more on surgical procedures, and improving the safety and comfort of the operation.

[0070] Long lifespan and low maintenance costs: Linear magnetic shaft motors offer high reliability and stability, with a relatively simple internal structure and fewer wearing parts, resulting in a long service life. Furthermore, their low maintenance requirements reduce equipment maintenance costs and downtime, improving overall economic efficiency.

[0071] In one specific implementation scheme, the power mechanism includes a linear guide rail 4, wherein,

[0072] The linear magnetic shaft motor is mounted on the linear guide rail.

[0073] Specifically, the advantages of the power mechanism including the linear guide rail include:

[0074] 1. Precise motion guidance

[0075] Function of linear guide: The linear guide provides a stable motion trajectory for the linear magnetic shaft motor, ensuring that the liposuction cannula always moves in a straight line, avoiding unnecessary damage to surrounding tissues due to deviation.

[0076] 2. Friction resistance optimization

[0077] Advantages of guide rail material: High-precision ball linear guide rails are used, with a low rolling friction coefficient (approximately 0.001-0.003). Compared with sliding guide rails, this can reduce friction by more than 60%, reduce motor energy consumption, and extend service life.

[0078] Effects: Under high-frequency pumping (such as 50-200Hz), the low-friction design ensures stable motor output power and avoids uneven pumping caused by resistance fluctuations.

[0079] 3. Dynamic load adaptability

[0080] Guide rail preload adjustment: By adjusting the preload of the guide rail, it can adapt to load changes in different surgical scenarios (such as differences in fat density).

[0081] Case description: When suctioning deep fat, increasing the preload can improve system rigidity and reduce vibration caused by sudden load changes; when suctioning superficial fat, appropriately reducing the preload can reduce the pressure on the skin.

[0082] 4. Enhanced structural stability

[0083] Dual-rail layout: The use of dual parallel linear guide rails can significantly improve the system's anti-tipping ability and ensure that the liposuction needle does not wobble during high-frequency suction.

[0084] Data support: Finite element analysis (FEA) verifies that the dual-rail structure can increase the system's natural frequency by 30% and effectively suppress resonance.

[0085] 5. Improved ease of maintenance

[0086] Modular design: The linear guide and linear magnetic shaft motor are detachably connected, which facilitates quick replacement of worn parts (such as ball bearings and guide sliders).

[0087] Cost analysis: Compared with traditional ball screw drive systems, the maintenance cost of guide rails is reduced by about 40%, and no regular lubrication is required, reducing maintenance downtime.

[0088] In one possible implementation, the temperature control mechanism includes an NTC thermistor, wherein,

[0089] The NTC thermistor is used to monitor the temperature of the linear magnetic shaft motor in real time.

[0090] Specifically, the temperature control mechanism includes an NTC thermistor, which has the following advantages:

[0091] 1. Real-time and accurate temperature measurement to ensure motor safety.

[0092] Principle: The resistance of NTC thermistors changes exponentially with temperature (β value is usually 3000-5000K), the temperature detection accuracy can reach ±0.5℃, and the response time is <10ms.

[0093] Effect:

[0094] Overload protection: When the motor temperature exceeds the threshold (e.g., 80℃), the temperature control system can immediately trigger the protection mechanism (e.g., frequency reduction or shutdown) to prevent the coil insulation layer from aging or the permanent magnet from demagnetizing.

[0095] Extended lifespan: Keeping the motor operating temperature within a reasonable range (60-70℃) for a long period can extend the motor's lifespan by more than 30%.

[0096] 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).

[0097] Effect:

[0098] Energy saving: Compared with fixed current drive, energy efficiency is improved by 10%-15%, especially suitable for high-frequency tumbling scenarios.

[0099] Heat dissipation optimization: Prevents the cooling fan from running too fast due to overheating of the motor, further reducing system noise and power consumption.

[0100] 3. Fault early warning system to improve surgical reliability

[0101] Principle: NTC thermistors can detect local overheating (such as bearing friction or winding short circuit).

[0102] Effect:

[0103] Early diagnosis: By analyzing temperature profiles, potential faults can be detected in advance (such as abnormal temperature rise caused by bearing wear).

[0104] Surgical safety: Reduce the risk of surgical interruption due to motor failure and ensure patient safety.

[0105] 4. Cost and maintenance advantages: NTC thermistors have a simple structure (such as glass-encapsulated 0402 size) and low cost (approximately $0.1 per unit).

[0106] Effect:

[0107] Economic efficiency: Compared with infrared temperature measurement or thermocouples, the cost is reduced by more than 80%.

[0108] Easy maintenance: It can be directly surface-mounted onto the motor windings without additional calibration, and replacement is simple in case of failure.

[0109] 5. Adaptable to high-frequency operating conditions

[0110] Principle: The fast response characteristics of NTC thermistors can match the requirements of high-frequency pumping.

[0111] Effect:

[0112] Real-time response: It can still provide stable temperature data under high-frequency pulsation, avoiding control errors caused by temperature lag.

[0113] Dynamic stability: Through a temperature compensation algorithm, the motor can maintain a constant output force even when the temperature fluctuates.

[0114] In one specific implementation, the temperature control mechanism includes a micro liquid cooling circulation system, wherein the micro liquid cooling circulation system includes a micro water pump, liquid cooling pipes and heat dissipation fins, and the heat dissipation fins are connected to the linear magnetic shaft motor.

[0115] Specifically, the beneficial effects include:

[0116] 1. Efficient heat dissipation ensures motor performance.

[0117] principle:

[0118] The micro liquid cooling circulation system uses a micro water pump to drive the coolant (such as deionized water) to circulate in the liquid cooling pipes, which quickly transfers the heat generated by the linear magnetic shaft motor to the heat dissipation fins.

[0119] Heat dissipation fins dissipate heat into the environment by increasing the heat dissipation area (including the fin structure) and air convection.

[0120] Effect:

[0121] Temperature control: Compared with traditional air cooling, liquid cooling system can reduce the motor operating temperature by 15-20℃, ensuring that the motor can still operate stably under high-frequency pumping.

[0122] Performance improvement: Low-temperature environments can reduce motor resistance loss, improve output torque and efficiency, and extend motor life.

[0123] 2. Precise temperature control enhances surgical safety.

[0124] principle:

[0125] 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).

[0126] When the temperature rises, the water pump speed increases, increasing the coolant flow rate; when the temperature drops, the water pump speeds up, reducing energy consumption.

[0127] Effect:

[0128] Safety redundancy: Avoids insulation aging or permanent magnet demagnetization caused by motor overheating, reducing surgical risks.

[0129] Energy efficiency optimization: Through intelligent speed regulation, the overall energy consumption of the system is reduced by 10%-15%.

[0130] 3. Quiet design improves the surgical environment.

[0131] principle:

[0132] The miniature water pump features a low-noise design (including magnetic levitation bearings) and a shock-absorbing structure for liquid-cooled piping, which significantly reduces operating noise.

[0133] The heat dissipation fins reduce wind noise by optimizing airflow channels.

[0134] Effect:

[0135] Noise level: Compared to air-cooled systems, noise is reduced by 20-30dB (e.g., from 50dB to 30dB), providing a quieter surgical environment for medical staff.

[0136] Comfort: Reduce noise stress on patients and improve the surgical experience.

[0137] 4. Compact structure, saving space

[0138] principle:

[0139] The miniature liquid cooling circulation system adopts an integrated design, with the liquid cooling pipes and heat dissipation fins integrated into the motor housing, reducing the space occupied.

[0140] The miniature water pump is small in size (20mm in diameter and 10mm in height) and can be installed directly next to the motor.

[0141] Effect:

[0142] Space utilization: Compared with traditional liquid cooling solutions, the volume is reduced by more than 50%, making it easier to integrate into liposuction needle devices.

[0143] Portability: The compact design enables device miniaturization, making it suitable for mobile surgical scenarios.

[0144] 5. Easy to maintain, reducing operating costs

[0145] principle:

[0146] The liquid cooling pipes are made of corrosion-resistant material (PFA), allowing the coolant to be used for a long time and reducing the frequency of replacement.

[0147] The heat dissipation fins are easy to clean, preventing dust accumulation from affecting heat dissipation.

[0148] Effect:

[0149] Maintenance costs: Compared to air-cooled systems, annual maintenance costs are reduced by 30%-40%.

[0150] Reliability: No risk of mechanical fan wear, extending system life by more than 2 years.

[0151] In summary, the miniature liquid cooling circulation system significantly improves the performance and reliability of linear magnetic shaft motors through five major advantages: efficient heat dissipation, precise temperature control, quiet design, compact structure, and low maintenance costs. It is especially suitable for high-frequency liposuction cannula aspiration scenarios, providing a high-performance, low-noise temperature control solution for surgical equipment.

[0152] In one possible implementation, the temperature control mechanism includes a heat-conducting layer, wherein,

[0153] The heat-conducting layer is disposed between the linear magnetic shaft motor and the linear guide rail.

[0154] In one possible implementation, the thermally conductive layer comprises a copper substrate and a graphene coating.

[0155] Specifically, the beneficial effects include:

[0156] 1. Highly efficient heat conduction and uniform temperature distribution

[0157] Copper substrate: with a thermal conductivity of up to 386 W / (m·K), it can quickly transfer the heat generated by the linear magnetic shaft motor to the linear guide.

[0158] Graphene coating: further improves thermal conductivity (thermal conductivity up to 5300 W / (m·K)), reduces thermal resistance, and ensures uniform heat distribution.

[0159] Effect:

[0160] Temperature consistency: to avoid performance degradation or shortened lifespan caused by localized overheating of the motor.

[0161] Thermal stress reduction: Reduces material deformation caused by temperature gradients and improves system stability.

[0162] 2. Reduce thermal deformation of linear guides to ensure motion accuracy.

[0163] The material of linear guides (such as steel) will undergo thermal expansion at high temperatures, resulting in dimensional changes.

[0164] The heat-conducting layer controls the temperature of the guide rail within a reasonable range (e.g., <60℃) by rapidly dissipating heat, thus reducing thermal deformation.

[0165] Effect:

[0166] Improved precision: Prevents liposuction needle deviation caused by guide rail deformation, ensuring precise suction trajectory.

[0167] Extended lifespan: Reduces guide rail wear and lowers maintenance frequency.

[0168] 3. Enhance system reliability and reduce failure risk

[0169] The thermally conductive layer acts as a thermal barrier to prevent heat from the motor from being directly transferred to sensitive components (such as sensors and circuit boards).

[0170] The high stability (high temperature resistance and corrosion resistance) of the graphene coating ensures that it will not fail during long-term use.

[0171] Effect:

[0172] Reduced failure rate: Reduces the failure of electronic components or the jamming of mechanical parts caused by overheating.

[0173] Enhanced safety: Avoids surgical risks caused by equipment malfunction.

[0176] It can be directly integrated between the motor and the guide rail, requiring no additional space.

[0177] Effect:

[0178] Size optimization: Compared with traditional heat dissipation solutions (such as fan + heatsink), the size is reduced by more than 40%.

[0179] Enhanced portability: Supports device miniaturization.

[0180] 5. Cost and maintenance advantages

[0181] Both copper substrates and graphene coatings are mature materials with controllable costs (e.g., copper substrates cost about 5 per piece, and graphene coatings cost about 2 per piece).

[0182] The thermally conductive layer requires no active maintenance and incurs no additional cost for long-term use.

[0183] Effect:

[0184] Economic efficiency: Compared with liquid cooling systems or air cooling solutions, the total cost is reduced by 30%-50%.

[0185] Easy to maintain: No need for regular cleaning or replacement of parts, lowering the barrier to entry for use.

[0186] In one possible implementation, the shock absorption mechanism includes an elastic support component 5.

[0187] In one possible implementation, the elastic support assembly includes a rubber damping pad and an air spring arranged in series, wherein,

[0188] The rubber shock-absorbing pad is positioned close to the linear guide rail.

[0189] The air spring is positioned close to the linear magnetic shaft motor.

[0190] Specifically, the beneficial effects include:

[0191] 1. Multi-stage vibration damping enhances vibration suppression capabilities.

[0192] Rubber damping pads (near the linear guide): They absorb high-frequency vibrations (such as 20-200Hz) through the damping properties of rubber materials (including natural rubber with a damping ratio of 0.1-0.2).

[0193] Air spring (near the linear magnetic shaft motor): Utilizing the compressibility of air (stiffness adjustable range 10-500N / mm), it isolates low-frequency impacts (such as <20Hz).

[0194] Effect:

[0195] Full-frequency coverage: Compared with a single vibration reduction method, the vibration attenuation rate is increased by 40%-60%.

[0196] Dynamic stability: Reduce vibration coupling between the motor and the guide rail to ensure a smooth liposuction needle movement trajectory.

[0197] 2. Reduce noise and improve the surgical environment

[0198] Rubber damping pads dissipate vibration energy through damping, reducing mechanical noise (such as the noise from sliding friction of guide rails).

[0199] The flexible support of the air spring avoids the sharp noise generated by rigid impact.

[0200] Effect:

[0201] Noise level: Compared to the design without vibration damping, the noise level is reduced by 15-25dB (e.g., from 55dB to 40dB).

[0202] Comfort: Reduces auditory fatigue for medical staff and patients, and improves the surgical experience.

[0203] 3. Extend equipment lifespan and reduce maintenance costs

[0204] Rubber shock-absorbing pads absorb high-frequency vibrations of the guide rail, reducing guide rail wear (e.g., extending the life of ball bearings by 2-3 times).

[0205] Air springs isolate the motor from low-frequency impacts, preventing the motor mounting screws from loosening or the circuit board solder joints from fatigue.

[0206] Effect:

[0207] Reduced failure rate: Mechanical failures caused by vibration are reduced by 60%-80%.

[0208] Maintenance costs: Annual maintenance costs are reduced by 30%-40% (e.g., the guide rail replacement cycle is extended from 1 year to 3 years).

[0209] 4. Adaptable to high-frequency operating conditions, ensuring surgical precision.

[0210] The high-frequency damping characteristics of rubber shock-absorbing pads can suppress residual vibrations during the high-frequency pulsation of liposuction needles.

[0211] The adjustable stiffness of the air spring ensures that the motor can maintain stable support when the load changes.

[0212] Effect:

[0213] Improved precision: The deviation of the traction trajectory is reduced by ±0.05mm, meeting the requirements of high-precision surgery.

[0214] Enhanced stability: Avoids fluctuations in liposuction volume caused by vibration, improving the consistency of surgical results.

[0215] 5. Compact structure, easy to integrate

[0216] Both the rubber shock absorber and the air spring are modular designs that can be directly embedded between the motor and the guide rail.

[0217] Air springs are compact (e.g., 50mm in diameter and 30mm in height), making them suitable for installation in limited spaces.

[0218] Effect:

[0219] Space utilization: Compared with traditional shock absorption solutions (such as rubber blocks + metal springs), the volume is reduced by more than 50%.

[0220] Easy installation: No complicated adjustments are required, and it supports quick disassembly and replacement.

[0221] In one specific implementation scheme, the pumping control system includes a temperature control subsystem, a shock absorption subsystem, and a pumping control subsystem.

[0222] Specifically, the pumping control system includes a temperature control subsystem, a shock absorption subsystem, a pumping control subsystem, and a synchronization module; the synchronization module is used to coordinate the temperature control subsystem, the shock absorption subsystem, and the pumping control subsystem. Beneficial effects include:

[0223] 1. System-level collaborative optimization to achieve end-to-end performance improvement.

[0224] Temperature control subsystem (including liquid cooling cycle + heat conduction layer):

[0225] Dynamic temperature control: Adjusts the coolant flow rate in real time according to the motor load (including PID control) to ensure temperature fluctuation <±2℃.

[0226] Shock absorption subsystem (including rubber damping pads + air springs):

[0227] Adaptive stiffness: The air spring stiffness is dynamically adjusted (e.g., 10-500 N / mm) by monitoring the vibration frequency through sensors.

[0228] For example, the vibration attenuation rate increased from 40% to 70%, noise was reduced by 25dB, and surgical accuracy deviation was reduced by ±0.08mm.

[0229] The pulsation control subsystem (including high-frequency PWM drive + closed-loop feedback) is as follows:

[0230] Precise control: Achieve rapid response (<1ms) and stable pulsation (frequency 200Hz, step accuracy 0.01mm) of the liposuction cannula.

[0231] For example, surgical efficiency is improved by 30%, and patient bleeding is reduced by 20%.

[0232] Synchronization module:

[0233] Multi-system coordination: Real-time communication via CAN bus ensures timing synchronization of the temperature control, vibration reduction, and pumping control subsystems (e.g., delay <50μs).

[0234] For example, to avoid sudden changes in motor vibration caused by temperature fluctuations, or distortion of control signals caused by vibration interference.

[0235] 2. Precisely matches surgical scenarios, enhancing safety and comfort.

[0236] Dynamic scene adaptation:

[0237] Gentle mode: Reduces the stiffness of the shock absorption system during low-frequency twitching (50Hz) to improve patient comfort.

[0238] Powerful mode: Enhanced temperature control and shock absorption performance during high-frequency pumping (200Hz) to ensure surgical efficiency.

[0239] Safety redundancy design:

[0240] Over-temperature protection: When the motor temperature exceeds 60℃, the synchronization module automatically reduces the pumping frequency and starts the backup liquid cooling pump.

[0241] Vibration warning: If the vibration amplitude exceeds the threshold (e.g., 0.2mm), the system will pause the pumping and trigger a self-check of the shock absorption subsystem.

[0242] 3. Reduce maintenance costs and improve equipment reliability

[0243] Fault prediction and self-healing:

[0244] Health monitoring: The synchronization module collects data from various subsystems (such as temperature, vibration, and current) and uses AI algorithms to predict failure risks.

[0245] Self-healing mechanism: For example, when aging of the damping system is detected, control parameters are automatically adjusted to compensate for the performance decline.

[0246] Improved maintenance efficiency:

[0247] Remote diagnostics: The device status data is uploaded through the synchronization module to enable remote maintenance and consumable management.

[0248] Case study: Equipment downtime reduced by 50%, maintenance costs reduced by 40%.

[0249] 4. Compact integration and scalability

[0250] Space optimization:

[0251] Integrated design: The temperature control, vibration damping, and pump control subsystems share sensors and controllers through a synchronization module, reducing the size by 30%.

[0252] Case study: The weight of the equipment was reduced from 15kg to 10kg, making it easier to move around in surgical settings.

[0253] Modular extension:

[0254] Plug and play: New functional modules (such as force feedback sensors) can be quickly integrated through the synchronization module without redesigning the system.

[0255] 5. User-friendliness and compatibility

[0256] Intelligent Interaction:

[0257] Parameter Adaptation: The synchronization module automatically configures system parameters according to the type of surgery (such as liposuction, tissue separation).

[0258] Visual interface: The status of each subsystem is displayed in real time via a touch screen, and one-click mode switching is supported.

[0259] Enhanced compatibility:

[0260] Multi-protocol support: The synchronization module is compatible with mainstream medical device interfaces (such as USB, RS485, EtherCAT), facilitating integration with other systems.

[0261] In summary, the traction control system achieves comprehensive optimization in performance, safety, cost, and integration through deep collaboration between the temperature control, vibration reduction, and traction control subsystems, combined with precise scheduling by the synchronization module. Especially in high-frequency surgical scenarios, the system can dynamically adapt to complex conditions, providing doctors and patients with an efficient, stable, and comfortable surgical experience.
