Description
Technical Field
[0001] The present invention relates to the technical field of ultrasonic surgical equipment, and in particular to an ultrasonic surgical aspiration system. Background Art
[0002] In modern surgery, especially minimally invasive surgery and delicate surgery, precise operating tools and techniques are essential to ensure the success of the operation. Traditional surgical instruments usually rely on mechanical cutting or electrosurgical methods, but these methods have some limitations, such as insufficient cutting accuracy, greater risk of thermal damage, and inability to achieve multiple functions (such as cutting and suction) at the same time. In recent years, ultrasonic surgical equipment has gradually gained favor due to its higher cutting accuracy, lower risk of thermal damage, and multifunctional integration. Ultrasonic surgical equipment generates mechanical energy through high-frequency vibration, which can effectively cut and coagulate tissues, and can also achieve the function of tissue decomposition under appropriate conditions. In addition, combined with negative pressure suction technology, the waste generated during the operation can be removed in real time, keeping the surgical field clear and reducing the risk of infection.

[0071] The beneficial effects of the present invention are as follows: an ultrasonic surgical aspiration system of the present invention obtains power parameters through a main control module, generates a start signal corresponding to the parameters, and controls the power drive unit to generate a high-frequency drive power supply through the start signal. The introduction of the main control module ensures precise control of the power parameters. Traditional ultrasonic surgical equipment is relatively extensive in power regulation, while the present system can obtain the power parameters set by the user in real time and accurately through the main control module, and generate a corresponding start signal. This not only improves the stability during the operation, but also enhances the controllability of the operation. Especially in complex surgical environments, this high-precision power control capability is crucial and can significantly reduce misoperation and unnecessary tissue damage.
[0072] In an ultrasonic surgical aspiration system of the present invention, each operating handle device is used to generate ultrasonic vibration based on a high-frequency driving power supply after the user triggers a switch to achieve cutting, coagulation, decomposition or aspiration functions. Each operating handle device integrates multiple functions (such as cutting, coagulation, decomposition and aspiration), allowing doctors to complete multiple surgical tasks on one operating handle, simplifying the surgical process and reducing the time for changing instruments, thereby shortening the operation time and reducing the surgical risk for patients. The multifunctional integrated design significantly improves surgical efficiency and safety.
[0073] An ultrasonic surgical suction system of the present invention, each first pipeline kit includes a first suction tube, a connector and a valve made of a flexible corrosion-resistant material, connected to an external waste collection device, an integrated component, a filter and a suction tank. The efficient waste disposal mechanism is a highlight of this system. The first pipeline kit adopts a flexible corrosion-resistant material to ensure the durability and flexibility of the suction tube; the design of the connector and the valve allows flexible adjustment of the suction force and prevents leakage. The external waste collection device collects multiple suction tubes into the second suction tube through an integrated component, and after the large particles of impurities are removed by the filter, they are finally stored in the suction tank. This design not only maintains a clear surgical field of view, but also reduces the risk of infection and improves the cleanliness and hygiene standards of the surgical environment.
[0074] An ultrasonic surgical aspiration system of the present invention includes a dripping control unit, a negative pressure vacuum pump, a negative pressure suction port, a pressure monitoring unit and a second pipeline kit. The dripping control unit adjusts the passage opening ratio of the negative pressure vacuum pump through a proportional solenoid valve to ensure that the deviation between the actual negative pressure value and the set value is within 10%. The pressure monitoring unit collects the actual negative pressure value of the negative pressure suction port in real time, and feeds the data back to the dripping control unit, thereby realizing precise control of the negative pressure attraction strength. This real-time feedback mechanism not only improves the safety of the operation, but also can timely adjust the negative pressure parameters to adapt to different surgical needs, ensuring the best surgical effect.
[0075] An ultrasonic surgical aspiration system of the present invention includes a display driver module, which receives operation parameters input by a user and sends them to a main control module. The display driver module provides an intuitive user interface, and the user can conveniently input and view operation parameters (such as power parameters, negative pressure suction setting values, and peristaltic pump speed setting values) through the display screen. This user-friendly interface not only simplifies the operation process, but also improves the transparency and controllability of the operation, allowing doctors to focus more on the operation itself.
[0076] An ultrasonic surgical aspiration system of the present invention includes a foot pedal device, which provides an excitation function unit and a parameter adjustment function unit. The foot pedal device allows doctors to trigger different modes (such as ultrasonic vibration mode, negative pressure aspiration mode or infusion mode) through a foot switch, and adjust the corresponding operating parameters by stepping on the force, position, duration, etc. This design frees the doctor's hands, allowing him to quickly switch modes and adjust parameters without interrupting the surgical operation, greatly improving the convenience and efficiency of the operation.
[0077] An ultrasonic surgical suction operation system of the present invention includes a power supply device and a fan for cooling a main control module. The transformer module receives the industrial frequency input power and converts it into multiple output power supplies, which respectively power different components to ensure the stable operation of the system. The fan is used to cool the main control module to prevent overheating, extend the service life of the equipment, and ensure the safety of the surgical process. The multi-level power distribution design not only improves the reliability of the system, but also optimizes the energy utilization efficiency.
[0078] The present invention discloses an ultrasonic surgical suction operation system, wherein the power driving unit includes an impedance matching unit, a signal amplifying unit, a transformer driving unit and a phase feedback unit. The impedance matching unit, the signal amplifying unit and the phase feedback unit work together to form a self-excited oscillation loop, ensuring that the sinusoidal wave signal output by the transducer has a stable phase and amplitude. This design optimizes the working performance of the transducer, improves the stability and consistency of ultrasonic vibration, and further enhances the surgical effect.
[0079] An ultrasonic surgical suction operation system of the present invention comprises an operating handle seat, a ring light control unit and a ring light. The ring light indicates the use status of the operating handle by changing color, so that the doctor can understand whether the handle is placed correctly. The default color of the ring light is a first color. When the operating handle is removed from the handle seat, the color of the ring light changes to a second color. This status indication mechanism improves the safety and convenience of surgical operations, ensuring that the doctor can quickly understand the use of the handle and avoid misoperation.

[0082] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.
[0083] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0084] Embodiment 1
[0085] See also Figure 1 This embodiment provides an ultrasonic surgical aspiration system, comprising:
[0086] A main control module, used to obtain power parameters and generate a start signal corresponding to the parameters, and control the power drive unit to generate a high-frequency drive power supply through the start signal;
[0087] At least one operating handle device, wherein each operating handle device is used to generate ultrasonic vibrations capable of cutting, coagulating, decomposing or aspirating target tissue based on the high-frequency driving power source after the user triggers a switch;
[0088] The operating handle device comprises an operating handle and an ultrasonic head mounted on the operating handle;
[0089] Each operating handle device is connected to a respective first pipeline kit for sucking waste generated during the operation, and each first pipeline kit is connected to an external waste collection device.
[0090] In this embodiment, the main control module can receive power parameters (such as output power, frequency, etc.) set by the user through an interface or external device. These parameters determine the intensity and frequency of ultrasonic vibrations, thereby affecting the surgical effect. According to the received power parameters, the main control module generates a corresponding start signal. The start signal is used to control the working state of the power drive unit to ensure that it generates a high-frequency drive power supply that meets the requirements. In this embodiment, the main control module can achieve high-precision control of power parameters to ensure stability and controllability during the operation. Through a closed-loop control system, the main control module can monitor and adjust various parameters in real time to ensure the best surgical effect.
[0091] In this embodiment, after receiving the start signal sent by the main control module, the power drive unit is responsible for generating a high-frequency drive power supply. This high-frequency power supply provides the necessary energy for the subsequent ultrasonic head, enabling it to generate ultrasonic vibrations. The power drive unit adopts an efficient circuit design, which can effectively convert electrical energy into a high-frequency drive power supply, thereby improving energy utilization efficiency. Through impedance matching and phase feedback mechanisms, the power drive unit ensures the stability and consistency of the output signal, avoiding surgical risks caused by fluctuations. The operating handle, which is the part that the doctor directly controls, integrates multiple function buttons and switches to facilitate doctors to perform various operations. The ultrasonic head is installed at the front end of the operating handle and is the part that actually performs ultrasonic vibrations. The ultrasonic head generates mechanical vibrations through a high-frequency drive power supply, and can perform operations such as cutting, coagulation, decomposition or suction on the target tissue. When the user presses the trigger switch, the operating handle device generates ultrasonic vibrations based on the high-frequency drive power supply to perform predetermined surgical tasks. Each operating handle device integrates multiple functions (such as cutting, coagulation, decomposition and suction), simplifies the surgical process, and reduces the time for changing instruments.
[0092] Each First Line Kit includes:
[0093] A first suction tube made of a flexible corrosion-resistant material, wherein a first end of the first suction tube is connected to an operating handle via a connecting device and is used to suck waste generated during surgery;
[0094] At least one connector and valve, connecting the second end of the first suction tube with an external waste collection device, for adjusting the suction force and preventing leakage, the connector and valve are integrated into the operating handle or controlled by an operating interface on the operating handle;
[0095] The external waste collection device comprises in sequence:
[0096] An integrated component, used for connecting the first ends of all the first suction tubes together to the first ends of the second suction tubes;
[0097] A filter, disposed at the second end of the second suction tube, for filtering out large particles of impurities in the waste of the integrated assembly;
[0098] Suction canister, used to store waste suctioned during surgery.
[0099] Each operating handle device is connected to a respective first pipeline kit for sucking waste generated during surgery. The kit includes a first suction tube made of a flexible corrosion-resistant material, a joint and a valve. All first suction tubes are collected into a second suction tube, and after passing through a filter to remove large particles of impurities, they are finally stored in a suction tank.
[0100] The first suction tube is responsible for quickly removing waste such as blood and tissue debris generated during surgery to keep the surgical area clean. The design of the joint and valve allows flexible adjustment of the suction force and prevents leakage, ensuring the sealing and safety of the system. The external waste collection device centrally processes all the suctioned waste, facilitating postoperative cleaning and reducing the risk of contamination.
[0101] In this embodiment, the first suction tube made of flexible corrosion-resistant material has good flexibility and durability. During long surgical operations, the suction tube needs to be bent and moved frequently. The flexible material ensures that the suction tube will not break or get blocked due to bending, while the corrosion resistance prevents the suction tube from being damaged by contact with blood and other chemicals. For example, in orthopedic surgery, the suction tube needs to move flexibly following the doctor's operation, and the flexible material ensures its flexibility and reliability. In neurosurgery, doctors need to make fine adjustments to the suction force to avoid damaging surrounding tissues. The connectors and valves integrated in the operating handle allow doctors to quickly adjust the suction force through simple button or knob operations, ensuring precise control during surgery. In addition, this design reduces external connection points, reduces the risk of leakage, and ensures the sealing and safety of the system.
[0102] In this embodiment, when multiple operations are performed simultaneously, each operating table is equipped with an independent operating handle device. The integrated component collects the waste from all the first suction tubes into one second suction tube, which reduces the space occupied by the equipment and facilitates management and maintenance. For example, in the operating room of a large hospital, centralized waste processing can improve work efficiency and reduce postoperative cleaning time. In some complex surgical operations, such as tumor resection operations, large tissue debris may be generated. The filter can effectively intercept these large particles of impurities, prevent them from entering the suction canister, and avoid clogging and damage to the suction canister. For example, in plastic surgery, the filter can block larger fat particles, ensure the normal operation of the suction canister, and improve the stability and reliability of the system.
[0103] In the practical application of this embodiment, the system further includes:
[0104] A display driving module, used for receiving any operation parameter input by a user and sending the operation parameter to a main control module;
[0105] The operating parameters include: power parameters, negative pressure suction setting value, and peristaltic pump speed setting value.
[0106] In this embodiment, the display driver module is an important component of the ultrasonic surgical suction system, which is responsible for receiving the operating parameters input by the user and sending these parameters to the main control module. In this way, the doctor can adjust and monitor various key parameters in real time during the operation to ensure the safety and effectiveness of the operation. For example, in orthopedic surgery, the doctor needs to adjust the power of the ultrasonic head according to the hardness of the bone. For example, when cutting harder bones, the doctor can set a higher power value through the display driver module; when dealing with softer tissues, the power can be reduced to avoid excessive damage to surrounding tissues.
[0107] The display driver module receives the negative pressure suction setting value set by the user and passes it to the main control module for control. The negative pressure suction setting value determines the suction strength, which affects the speed and effect of waste removal. In neurosurgery, doctors need to finely control the suction strength to avoid damaging the surrounding sensitive nerve tissue. For example, doctors can set a lower negative pressure suction value to gently remove a small amount of blood or tissue debris; when a large amount of liquid needs to be removed quickly, the negative pressure suction value can be increased.
[0108] The display driver module receives the peristaltic pump speed setting value set by the user and sends it to the main control module. The peristaltic pump is used to control the drip rate or other fluid transfer tasks, and its speed directly affects the fluid delivery volume. In plastic surgery, doctors may need to use the drip mode to provide local anesthesia or inject drugs to patients. Through the display driver module, doctors can set the speed of the peristaltic pump to control the drip rate of the drug. For example, when slow drip is required, the doctor can set a lower speed; when fast drip is required, the speed can be increased.
[0109] Specifically, the system further includes: a droplet suction control unit, a negative pressure vacuum pump, a negative pressure suction port, a pressure monitoring unit, and a second pipeline kit;
[0110] The droplet suction control unit is connected to the negative pressure vacuum pump and is used to adjust the passage opening ratio of the negative pressure vacuum pump through a proportional solenoid valve to control the negative pressure suction pressure generated by the negative pressure vacuum pump outlet;
[0111] The outlet of the negative pressure vacuum pump is connected to the negative pressure suction port, and the negative pressure suction port is connected to the suction tank through a second pipeline kit; wherein the second pipeline kit is a third suction tube;
[0112] The pressure monitoring unit is used to collect the actual negative pressure value of the negative pressure suction port and feed the actual negative pressure value back to the droplet suction control unit;
[0113] The droplet suction control unit is also used to dynamically adjust the opening of the proportional solenoid valve according to the deviation between the actual negative pressure value and the negative pressure suction set value in the main control module to ensure that the deviation between the actual negative pressure value and the negative pressure suction set value is within 10%.
[0114] In this embodiment, the drip control unit adjusts the passage opening ratio of the negative pressure vacuum pump through a proportional solenoid valve to accurately control the negative pressure suction pressure. The negative pressure suction pressure can be dynamically adjusted according to the set value to ensure that the deviation between the actual negative pressure value and the set value is within 10%, thereby improving the safety and effect of the operation. Through a closed-loop control system, the negative pressure value is monitored and adjusted in real time to avoid surgical risks caused by pressure fluctuations. In neurosurgery, doctors need to make fine adjustments to the suction force to avoid damaging surrounding sensitive tissues. For example, when the doctor sets the negative pressure suction value to 20kPa, the drip control unit will accurately adjust the passage opening of the negative pressure vacuum pump through a proportional solenoid valve to ensure that the actual negative pressure value is stable between 18 and 22kPa, thereby achieving accurate waste suction and protecting surrounding tissues from damage.
[0115] The outlet of the negative pressure vacuum pump is directly connected to the negative pressure suction port to ensure that the negative pressure can be efficiently transmitted to the surgical area. The negative pressure generated by the negative pressure vacuum pump can be quickly and stably transmitted to the negative pressure suction port to ensure the continuity and stability of the suction process. For example, in plastic surgery, doctors need to quickly remove a large amount of blood and tissue debris generated during the operation. The direct connection design between the negative pressure vacuum pump and the negative pressure suction port ensures that the negative pressure can be quickly transmitted to the surgical area, achieving efficient waste suction, maintaining a clear surgical field of view, and improving surgical efficiency.
[0116] The second pipeline kit connects the negative pressure suction port to the suction canister for centralized processing and storage of wastes sucked during surgery. All sucked wastes are collected into the suction canister through the third suction tube, which is convenient for postoperative cleaning and disposal, reducing the risk of contamination. All sucked wastes are collected into the suction canister through the third suction tube, which is convenient for postoperative cleaning and disposal, reducing the risk of contamination. In the operating rooms of large hospitals, multiple operating tables perform surgeries simultaneously. The second pipeline kit collects wastes from all suction tubes into one suction canister, simplifying the waste management process and improving work efficiency. The filter effectively intercepts large particles of impurities, prevents clogging of the suction canister, and ensures the long-term stable operation of the system.
[0117] The pressure monitoring unit collects the actual negative pressure value of the negative pressure suction port in real time and feeds the data back to the drip control unit. The drip control unit automatically adjusts the opening of the proportional solenoid valve according to the deviation between the actual negative pressure value and the set value to achieve dynamic balance of negative pressure. For example, in cardiac surgery, real-time monitoring of negative pressure values is crucial. The pressure monitoring unit collects the actual negative pressure value of the negative pressure suction port once a second and feeds the data back to the drip control unit. If it is detected that the negative pressure value deviates from the set value by more than 10%, the drip control unit will immediately adjust the opening of the proportional solenoid valve to ensure that the negative pressure value quickly returns to the set range to ensure the safety of the operation.
[0118] In this embodiment, the drip control unit works in conjunction with the proportional solenoid valve to ensure precise regulation of the negative pressure suction pressure, thereby improving the safety and effectiveness of the surgery. The direct connection design between the negative pressure vacuum pump and the negative pressure suction port ensures efficient transmission of negative pressure and the sealing of the system, reducing the risk of leakage. The second pipeline kit concentrates all attracted waste into the suction tank, simplifies the waste management process, and protects the suction tank from blockage and damage through the filter. The pressure monitoring unit collects and feeds back the actual negative pressure value in real time, and the drip control unit automatically adjusts the negative pressure according to the feedback data to ensure stability and safety during the operation.
[0119] Specifically, the system further comprises: a peristaltic pump; the peristaltic pump is also connected to the droplet suction control unit;
[0120] The droplet suction control unit is also used to control the rotation speed of the peristaltic pump to the rotation speed setting value.
[0121] In this embodiment, the peristaltic pump is connected to the drip control unit, which is responsible for controlling the speed of the peristaltic pump to the speed setting value set by the user. This design allows doctors to flexibly adjust the infusion speed according to surgical requirements to ensure the accurate delivery of drugs or flushing fluids. For example, in plastic surgery, doctors need to provide local anesthesia to patients. By setting the speed of the peristaltic pump through the display drive module, doctors can accurately control the infusion speed of anesthetic drugs. For example, when slow dripping is required, the doctor can set a lower speed; when fast dripping is required, the speed can be increased. This precise control ensures the accuracy of drug dosage and reduces the risk of overdose or underdose. It should be noted that the drip control unit not only controls the speed of the peristaltic pump, but also monitors the actual infusion speed in real time through a closed-loop control system, and automatically adjusts it according to the set value. If the actual infusion speed deviates from the set value, the drip control unit will immediately adjust the speed of the peristaltic pump to ensure the stability and consistency of the infusion speed.
[0122] In this embodiment, the system further comprises a pedal device;
[0123] The foot pedal device comprises a foot pedal interface and a foot switch device connected to the foot pedal interface, wherein the foot switch device comprises a foot switch, an excitation function unit and a parameter adjustment function unit;
[0124] Wherein, the excitation function unit and the parameter adjustment function unit are respectively connected to the main control module for communication;
[0125] The excitation function unit is used to obtain the user's foot-operated action on the foot switch, and trigger the operation mode of the ultrasonic surgical aspiration system through the foot-operated action;
[0126] The operation mode of the ultrasonic surgical aspiration system includes an ultrasonic vibration mode, a negative pressure aspiration mode or an instillation mode;
[0127] The parameter adjustment functional unit is used to adjust the operating parameters corresponding to the operating mode in the triggered operating mode through the stepping force, position, duration or pressing mode of the foot switch, and feed back the operating parameters to the main control module;
[0128] Wherein, the operating parameters corresponding to the ultrasonic vibration mode include power parameters;
[0129] The operation parameters corresponding to the negative pressure suction mode include a negative pressure suction setting value;
[0130] The operating parameters corresponding to the drip mode include the speed setting value of the peristaltic pump.
[0131] In this embodiment, the foot pedal device is an important component of the ultrasonic surgical suction system, which includes a foot pedal interface, a foot switch device (including a foot switch, an excitation function unit and a parameter adjustment function unit), and these components are used to trigger different operation modes and adjust parameters. This design frees the doctor's hands, allowing the doctor to flexibly control the various functions of the system without interrupting the surgical operation. The excitation function unit is used to obtain the user's foot pedal action on the foot switch, and trigger the operation mode of the ultrasonic surgical suction system through the foot pedal action. The operation mode of the system includes ultrasonic vibration mode, negative pressure suction mode or infusion mode. In neurosurgery, doctors need to frequently switch ultrasonic vibration modes to cut tissue or stop bleeding. Doctors can quickly trigger the ultrasonic vibration mode by stepping on the foot switch without manually pressing the button on the operating handle. This not only improves the operating efficiency, but also reduces hand fatigue. Negative pressure suction mode in plastic surgery: In plastic surgery, doctors may need to frequently remove blood and tissue debris from the surgical area. Doctors can quickly trigger the negative pressure suction mode by stepping on the foot switch to keep the surgical field clear and improve surgical efficiency.
[0132] In this embodiment, the parameter adjustment functional unit is used to adjust the operating parameters corresponding to the operating mode in the triggered operating mode through the stepping force, position, duration or pressing mode of the foot switch, and feed back the operating parameters to the main control module. The operating parameters corresponding to the ultrasonic vibration mode include power parameters; the operating parameters corresponding to the negative pressure suction mode include the negative pressure suction setting value; the operating parameters corresponding to the infusion mode include the speed setting value of the peristaltic pump. For example, in orthopedic surgery, the doctor needs to adjust the power of the ultrasonic head according to the hardness of the bone. For example, the doctor can set a lower power value for processing softer tissues by lightly stepping on the foot switch, and set a higher power value for cutting harder bones by stepping on the foot switch heavily. This flexibility ensures the best surgical effect.
[0133] Specifically, the system further includes: an operating handle seat, a ring light control unit, and a ring light;
[0134] An operating handle seat is used to place the operating handle when the operating handle is not in use;
[0135] The ring light control unit is used to monitor whether the operating handle is inserted into the handle seat and transmit the insertion status information of the handle to the main control module;
[0136] The main control module is used to receive the handle status information transmitted by the ring light control unit and display the insertion status of the handle on the display drive unit;
[0137] The ring light is connected to the ring light control unit and is used to indicate the use status of the handle through color changes, wherein the default color of the ring light is the first color, and when the operating handle is removed from the handle base, the color of the ring light changes to the second color.
[0138] In this embodiment, the operating handle seat is used to place the operating handle when it is not in use, ensuring safe storage and convenient access to the handle. Specifically, before the operation begins, all operating handles should be placed on the handle seat to ensure that the device is in standby mode. This is not only convenient for management and inspection, but also prevents the handle from accidentally falling or losing during the operation. During the operation, if the doctor needs to temporarily put down the operating handle (for example, to replace other instruments), the handle can be put back into the handle seat to ensure that the handle does not affect the surgical environment and is available at any time.
[0139] The ring light control unit monitors whether the operating handle is inserted into the handle seat, and transmits the handle insertion status information to the main control module. The main control module receives the handle status information transmitted by the ring light control unit, and displays the handle insertion status on the display drive unit. The ring light is connected to the ring light control unit and indicates the use status of the handle by color changes. The default color is the first color (such as green). When the operating handle is removed from the handle seat, the ring light color changes to the second color (such as red).
[0140] During surgical preparation, all operating handles are inserted into the handle holder, and the ring light is green, indicating that the handles are in standby mode. The color of the ring light allows the doctor to quickly confirm that all handles are correctly placed to ensure correct surgical preparation. When the doctor picks up the operating handle for surgery, the ring light turns red, immediately indicating that the handle is in use. This not only reminds the doctor to pay attention to the status of the handle, but also helps assistants or other personnel understand the current operation. After the interval or end of the operation, the doctor puts the handle back into the handle holder, and the ring light turns green again, indicating that the handle has been safely stored. This instant feedback mechanism helps keep the surgical environment clean and orderly, reducing the risk of misoperation.
[0141] The display drive unit displays the insertion status of the handle on the screen in real time, providing additional visual feedback. In large operating rooms, multiple ultrasonic surgical suction systems may be used simultaneously. Through the display drive unit, doctors and assistants can quickly view the status of the operating handle of each device on the screen to ensure that all devices are in the correct operating mode. For surgical scenarios that require remote monitoring, the handle status information provided by the display drive unit can help the remote medical team understand the progress of the operation in real time and provide necessary support and guidance.
[0142] The color change of the ring light intuitively indicates the use status of the handle, avoiding the risk of misoperation caused by unclear handle status. The instant feedback mechanism provided by the ring light and display driver unit ensures that doctors and assistants can understand the status of the handle at any time, improving the safety and reliability of the operation. The operating handle holder provides a safe storage location for the handle, which is easy to manage and check, reducing the time and complexity of surgical preparation. Through the color change of the ring light, the doctor can quickly confirm whether the handle is placed correctly to ensure that the surgical preparation is correct. The color change of the ring light and the visual feedback of the display driver unit make the operation more intuitive, reducing the learning cost and operation difficulty of the doctor. The status information provided by the ring light and display driver unit facilitates efficient communication between the surgical team and improves the efficiency of the operation. The ring light control unit monitors the insertion status of the handle in real time and transmits the information to the main control module to ensure the stable operation of the system. By standardizing the storage and use of the handle, the risk of equipment failure caused by improper use or storage of the handle is reduced.
[0143] In this embodiment, the operating handle further includes:
[0144] The operation mode selection switch is used for the user to select an operation mode among ultrasonic vibration mode, negative pressure suction mode or infusion mode;
[0145] The parameter adjustment switch is used to adjust the operation parameters corresponding to the operation mode selected by the user through the user's triggering, and feed back the operation parameters to the main control module.
[0146] For example, the operation mode selection switch is used for the user to select an operation mode from the ultrasonic vibration mode, the negative pressure suction mode or the drip mode. In neurosurgery, doctors may need to frequently switch between the ultrasonic vibration mode and the negative pressure suction mode. For example, the ultrasonic vibration mode is selected when cutting tissue, and the negative pressure suction mode is selected when removing blood and tissue debris. Through the operation mode selection switch, doctors can quickly switch modes to ensure the continuity and efficiency of the surgical process. In plastic surgery, doctors may need to use multiple modes to complete different tasks. For example, the negative pressure suction mode is selected when performing fat suction, and the drip mode is selected when injecting fillers. The operation mode selection switch allows doctors to easily switch between different modes in the same operation to meet complex surgical needs. The parameter adjustment switch is used to adjust the operation parameters corresponding to the operation mode selected by the user through the user's triggering, and feedback the operation parameters to the main control module. The operation parameters corresponding to the ultrasonic vibration mode include power parameters; the operation parameters corresponding to the negative pressure suction mode include negative pressure suction setting values; and the operation parameters corresponding to the drip mode include the speed setting value of the peristaltic pump.
[0147] In orthopedic surgery, doctors need to adjust the power of the ultrasonic head according to the hardness of the bone. For example, when the doctor selects the ultrasonic vibration mode, he can use the parameter adjustment switch to set a lower power value for processing softer tissues, or set a higher power value for cutting harder bones. This flexibility ensures the best surgical results.
[0148] During cardiac surgery, doctors need to carefully control the suction force to avoid damaging surrounding sensitive tissues. Doctors can select the negative pressure suction mode, and then use the parameter adjustment switch to set a lower negative pressure value for gentle removal of a small amount of blood, or a higher negative pressure value for rapid removal of a large amount of fluid. The real-time feedback mechanism ensures the accuracy and timeliness of parameter adjustment.
[0149] In plastic surgery, doctors may need to use drip mode to provide local anesthesia or injectable drugs to patients. Doctors can select the drip mode and then use the parameter adjustment switch to set a lower speed for slow dripping or a higher speed for fast dripping. This precise control ensures the accuracy of drug dosage and reduces the risk of overdose or underdose.
[0150] The operation mode selection switch allows doctors to quickly switch between different modes without interrupting the surgical operation, significantly improving the efficiency of the operation. The parameter adjustment switch allows doctors to flexibly adjust various parameters according to surgical needs to ensure the continuity and efficiency of the surgical process. The mode selection and parameter adjustment functions on the operating handle enable the system to adapt to different surgical scenarios, improving the versatility and applicability of the system. Doctors can flexibly adjust the operating parameters according to the specific surgical situation to achieve refined control and ensure the best surgical effect. The design of the operation mode selection switch and parameter adjustment switch is intuitive and easy to use, reducing the learning cost and operation difficulty of doctors. The parameter adjustment switch feeds back the operating parameters to the main control module in real time to ensure the accuracy and timeliness of parameter adjustment, and improve the safety and reliability of the operation. Through clear mode selection and parameter adjustment functions, doctors can clearly understand the current operation status and reduce the risk of misoperation caused by improper operation. All functions are integrated on one operating handle, reducing the use of external devices, reducing the complexity of the surgical environment, and improving the convenience and safety of operation.

The power supply unit includes a transformer module and multiple power distribution terminals, which can convert the industrial frequency input power into multiple output power supplies to supply different components. This design not only improves the reliability and safety of the system, but also optimizes energy utilization efficiency.
[0164] Transformer module: receives industrial frequency input power (such as 220VAC or 110VAC) and converts it into different output power. Power distribution terminals, each output power is connected to a specific system component through the corresponding power distribution terminal, ensuring that each component obtains the required power supply.
[0165] The fan is used to cool the main control module to prevent overheating due to long-term operation, extend the service life of the equipment, and ensure stable operation of the system.
[0166] During long and complex surgeries, the main control module may generate a lot of heat due to continuous operation. The fan can remove the heat in time through effective air circulation to keep the operating temperature of the main control module within a safe range. For example, when multiple surgeries are performed simultaneously, the fan can ensure that each main control module is in the best working condition to avoid failure or performance degradation caused by overheating.
[0167] The transformer module converts the industrial frequency input power into multiple output power supplies, ensuring that each component can obtain the required stable power supply and improving the overall reliability of the system. Through multiple power distribution terminals, even if a component fails, other components can still operate normally, enhancing the fault tolerance of the system. Appropriate output power is configured according to the needs of different components to avoid unnecessary energy waste and improve energy utilization efficiency. All power management and distribution are handled uniformly by the transformer module, which simplifies the system structure and reduces maintenance costs. The fan cooling system effectively prevents the main control module from overheating due to long-term operation, prolongs the service life of the equipment, and ensures the safe operation of the system. The fan monitors the temperature of the main control module in real time to ensure that it is always within the safe working range, reducing the risk of failure caused by excessive temperature. Stable and reliable power supply and effective cooling system ensure the continuity and stability of various functions during surgery and improve the user's operating experience. Through the clear interface provided by the display drive unit, doctors can monitor various parameters in real time to ensure the safety and effectiveness of the operation.
[0168] In this embodiment, the power drive unit includes:
[0169] The impedance matching unit is used to generate an initial feedback signal after the power drive unit starts the signal, and isolate the power drive unit start signal and the initial feedback signal to obtain an isolated start signal and an isolated initial feedback signal;
[0170] A signal amplifying unit, used to amplify the isolated initial feedback signal to obtain a first signal and a second signal with 180 degrees opposite phases;
[0171] A transformer driving unit, used to drive a power transformer using the first signal and the second signal, so that the power transformer outputs a sine wave signal, and obtains a driving power supply for the transducer after filtering the sine wave signal through an LC filter circuit;
[0172] A phase feedback unit, used to monitor the phase change information of the voltage in the output signal of the transducer, and feed back the phase change information to the impedance matching unit through a low-pass filter;
[0173] The impedance matching unit is further used to use the phase change information of the voltage in the output signal of the transducer as a feedback signal, and to obtain an isolated feedback signal by isolating the feedback signal, so that the power driving unit forms a self-excited oscillation loop;
[0174] The AC / DC power supply module is connected to the power supply connector of the power transformer to provide a 50-100V power supply to the power transformer.
[0175] The power drive unit is a key component responsible for generating high-frequency drive power in the ultrasonic surgical suction system. It includes an impedance matching unit, a signal amplification unit, a transformer drive unit, and a phase feedback unit. These components work together to ensure that the transducer can stably output high-quality ultrasonic vibrations. In addition, the AC / DC power supply module provides a stable power supply for the power transformer to ensure efficient operation of the system.
[0176] The impedance matching unit generates an initial feedback signal after the power driving unit starts the signal, and isolates the power driving unit start signal and the initial feedback signal to obtain an isolated start signal and an isolated initial feedback signal.
[0177] The signal amplification unit amplifies the isolated initial feedback signal to obtain two signals, the first signal and the second signal, which are 180 degrees opposite in phase. Signals with opposite phases can effectively balance the load, reduce harmonic distortion, and improve the quality of the output signal. For example, in long-term surgery, the balanced load design can extend the service life of the transducer and ensure that it is always in the best working condition.
[0178] The transformer drive unit drives the power transformer through the first signal and the second signal to make it output a high-quality sinusoidal signal. For example, in neurosurgery, the frequency and intensity of ultrasonic vibrations need to be precisely controlled. The transformer drive unit can ensure the purity of the output signal and avoid unnecessary interference. The LC filter circuit filters the sinusoidal signal to eliminate high-frequency noise and other interference components, ensuring that the transducer obtains a stable driving power supply. For example, in plastic surgery, filtering can reduce unnecessary vibrations and improve the precision and safety of the surgery.
[0179] The phase feedback unit is used to monitor the phase change information of the voltage in the output signal of the transducer, and feed back the phase change information to the impedance matching unit through a low-pass filter. The impedance matching unit is also used to use the phase change information of the voltage in the output signal of the transducer as a feedback signal, and isolate the feedback signal to obtain the isolated feedback signal, so that the power drive unit forms a self-excited oscillation loop. For example, the phase feedback unit monitors the phase change of the transducer output signal in real time to ensure that it is always in the best working state. For example, in cardiac surgery, real-time monitoring of phase changes can promptly detect and correct any deviations to ensure the stability and consistency of ultrasonic vibrations. Through the phase feedback mechanism, the power drive unit forms a self-excited oscillation loop to ensure that the frequency and amplitude of the output signal are always kept within the set range. For example, during long-term surgery, the self-excited oscillation loop can automatically adjust the output parameters to maintain the stable operation of the system and reduce the operating burden of the doctor.
[0180] The AC / DC power module provides a stable 50-100V power supply to the power transformer, ensuring that it can work properly under different working conditions. For example, when multiple devices are used at the same time, a stable power supply can ensure that each power transformer can obtain sufficient power to avoid performance degradation caused by power supply fluctuations. The AC / DC power module can adapt to different input voltages (such as 110VAC or 220VAC) and convert them internally to the required 50-100V output voltage, ensuring the versatility and applicability of the system. For example, in an international medical environment, this design allows the system to be used in different countries and regions without the need for additional power adapters.
[0181] The impedance matching unit ensures the stability and isolation of the start signal, prevents interference, and improves the reliability and safety of the system. The signal amplification unit and the transformer drive unit work together to ensure the high-quality output of the high-frequency drive power supply, meeting the needs of different surgeries. The phase feedback unit monitors the output signal of the transducer in real time to ensure that it is always in the best working state, improving the safety and effect of the surgery. Through the self-excited oscillation loop, the power drive unit can automatically adjust the output parameters to maintain the stable operation of the system and reduce the operating burden of the doctor. The AC / DC power supply module provides a stable 50-100V power supply for the power transformer to ensure that it can work normally under different working conditions and improve the overall performance of the system. The AC / DC power supply module can adapt to different input voltages to ensure the versatility and applicability of the system, and is suitable for medical environments around the world. Through real-time monitoring and feedback mechanisms, doctors can understand and adjust various parameters at any time to ensure the continuity and efficiency of the surgical process. The stable and reliable power supply and efficient cooling system simplify the system's maintenance process, reduce maintenance costs, and improve user satisfaction.

[0186] In this embodiment, the main control module is the core device of the system, providing power and control functions. The design supports single or multiple operating handles to meet different surgical needs. The multi-handle type allows collaborative treatment of multiple surgical sites.

[0190] The main control module and display driver module form the control center of the system and have the following functions:
[0191] Detect and control system frequency, voltage, temperature, suction negative pressure value, liquid flow, human-computer interaction, handle status, ultrasonic power, resonance status and parameter storage. The main control unit is responsible for real-time detection and adjustment of key system parameters, such as ultrasonic frequency, power supply, negative pressure, liquid flow, etc., while providing human-computer interaction interface and parameter storage functions.
[0192] The power drive unit is responsible for generating the ultrasonic power required by the system. The input information is the power parameters set by the touch screen component. The output frequency range is 20KHz-55KHz, and the implementation frequency is 25KHz. It provides the capacitor components, inductor components and voltage and current monitoring closed loops required for resonance to form a resonant state and ensure that the output characteristics are pure resistance (that is, by using components such as inductors and capacitors, the system forms a stable resonant state, so that the output power efficiency is optimized and the energy loss is minimized.). When the load pressure range is 0-100N, the transverse amplitude characteristics of the ultrasonic head are guaranteed to remain unchanged.
[0193] The power drive unit supports adaptive dynamic adaptation function, automatically adapting within the resonant frequency range, such as 25.125.7KHz, 34.134.7KHz, 55.1~55.8KHz, improving production consistency, surgical reliability and surgical effectiveness.
[0194] The drip control unit controls the saline drip rate and negative pressure suction pressure in the following ways:
[0195] The parameters are sent to the main control unit through the touch screen component, and the main control unit controls the speed of the peristaltic pump through the DAC, thereby adjusting the liquid dripping speed;
[0196] The proportion of the vacuum pump negative pressure passage is controlled by the proportional solenoid valve assembly, and the actual negative pressure value is detected by the pressure monitoring unit. Compared with the set value, the error is within ±10%.

[0202] The touch screen component has the following functions: integrated display and control, cutter head selection and control, channel selection for dual-channel models, parameter storage, including customary parameter storage and one-key callback, and parameter retention in the event of an accidental power failure.
[0203] See also Figure 2 The power drive unit in this embodiment includes: the impedance matching unit generates an initial feedback signal after the power drive unit receives the start signal. The power drive unit start signal is isolated from the initial feedback signal to ensure the independence of the signals. The isolated start signal and the isolated initial feedback signal are output for processing by subsequent units. The start-up efficiency of the system is improved and the influence of signal interference on the system is reduced. Reliable signal transmission is achieved to provide initial conditions for the self-excited oscillation of the power drive unit.
[0204] The signal amplification unit receives the isolated initial feedback signal, amplifies it and generates two signals. The two signals are the first signal and the second signal with a phase difference of 180 degrees. It provides a symmetrical signal source to drive the power transformer to ensure the efficient operation of the transformer. It ensures that the amplitude and phase characteristics of the system signal meet the power conversion requirements.
[0205] The transformer driving unit drives the power transformer with the first signal and the second signal to make it output a sine wave signal. The LC filter circuit is used to filter the sine wave signal to ensure the purity and stability of the output signal. Finally, the driving power supply of the transducer is generated. A high-quality driving power supply signal is provided to drive the transducer to output ultrasonic power. High-frequency noise and signal instability are eliminated by filtering to ensure the performance of the transducer.
[0206] The phase feedback unit monitors the voltage phase change information in the transducer output signal and captures the dynamic changes in the system operation status. The phase change information is fed back to the impedance matching unit through a low-pass filter. Closed-loop control is achieved to ensure that the transducer always operates in a resonant state. The stability and reliability of the system operation are improved.
[0207] The impedance matching unit (feedback signal processing) processes the voltage phase change information in the transducer output signal as a feedback signal. By isolating the feedback signal, the isolated feedback signal is obtained for the construction of a self-oscillation loop. The self-oscillation characteristics of the power drive unit are maintained so that the system can automatically adjust to the best working state when it changes dynamically. It provides precise signal matching, reduces energy loss, and improves power transmission efficiency.
[0208] The AC / DC power module is connected to the power supply connector of the power transformer to provide a 50-100V power supply to the power transformer.
[0209] The working principle of the power drive unit is that a weak initial signal is naturally generated due to factors such as noise in the circuit and power supply fluctuations. The initial signal is the starting condition for the self-excited oscillation process.
[0210] The initial signal is amplified by the amplifier until it is sufficient to drive the transducer.
[0211] The amplifier generates two signals with opposite phases to ensure symmetry and stability of the subsequent drive signal.
[0212] The transducer generates vibration under the action of the driving signal and returns the electrical parameter information (such as frequency, amplitude and phase) of the vibration signal to the driving circuit through a feedback loop.
[0213] The drive circuit adjusts the output frequency based on the feedback signal to match the mechanical resonance frequency of the transducer while optimizing the output amplitude.
[0214] The system enters a stable state under the action of feedback regulation and outputs a high-frequency AC signal consistent with the resonant frequency of the transducer. This signal has a stable frequency and amplitude and is used to drive the ultrasonic transducer to work efficiently.
