Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to an ultrasound treatment system for varicose veins. BACKGROUND

[0002] The high-intensity focused ultrasound system, also known as HIFU, is mostly used for tumor treatment in mature products in China. The system design is relatively large in size. The medium water and the guide ultrasound in the system are independent systems, and the single system cannot complete the overall operation when working independently.

[0003] Traditional varicose vein treatment usually adopts endoluminal therapy. The active treatment scheme of endoluminal laser ablation or endoluminal radiofrequency ablation damages the vein wall under high heat and eventually closes the vein wall, or the passive scheme of stripping or injecting vein glue isolates the lesion point. The above-mentioned therapies will form several wounds on the patient's thigh or calf, and the active treatment scheme needs to reopen the wound for repeated treatment when the closure is not tight after the operation, causing secondary damage to the wound.

[0004] A French company designed a high-intensity focused ultrasound extracorporeal treatment system for varicose veins. The system uses ultrasound as energy, emits ultrasound from the outside of the body into the body, focuses during the emission process, generates heat energy at a point, forms a high-temperature treatment point, causes coagulative necrosis of the vein wall, and realizes the closure of the blood vessel wall. However, the device is relatively large in size, and the medium for ultrasound transmission needs to be obtained through other systems, which limits the application scenarios. In addition, the treatment ultrasonic transducer and its driver design are limited, and the energy output is low, which makes it impossible to close the vein wall in a short time. SUMMARY

[0005] The present application provides an ultrasound treatment system for varicose veins, which does not require an external independent ultrasound image and does not require an external independent water supply, and can complete the complete treatment of varicose vein surgery.

The main control unit obtains whether each unit is online or not based on this.

[0011] Furthermore, under normal working conditions, each unit will start a timer and connect to the main control unit. The main control unit will send a heartbeat packet to each unit for a short period of time. After receiving this instruction, each unit will integrate the status information and the heartbeat packet into a data packet and send it to the main control unit. At the same time, each unit will reset the timer and restart the timing. If each unit does not receive the heartbeat packet sending instruction from the main control unit after the timer is accumulated, each unit will automatically restart and enter the standby state, waiting for the main control unit to wake up; If the main control unit sends a heartbeat packet sending instruction and does not receive the heartbeat packets sent by each unit within the set time, the main control unit will repeatedly send the heartbeat packet sending instruction at the set interval; If the main control unit still does not receive the heartbeat packet from each unit within the time defined by the timer of each unit, the main control unit will restart all units on the trolley.

[0012] Specifically, the acoustic focal length of the focusing transducer is between 30 mm and 50 mm, and the overall aperture is designed to be between 50 mm and 70 mm;

[0013] The guiding image transducer protrudes from the emitting surface of the focusing transducer by 1-7 mm.

[0014] Specifically, an ultrasonic sound-transmitting component is provided at the position of the treatment head facing the affected part of the patient, and is detachably assembled from a plastic film with a set tensile strength and a set sound transmittance and a fixing piece for fixing the plastic film.

[0015] More specifically, the transverse and longitudinal tensile strengths of the plastic film are between 10 MPa and 20 MPa, and a material with a Shore hardness of 70A and a sound transmittance of 90% is selected.

[0017] More specifically, a distance sensor is also provided on the treatment head, which is installed at the top of the treatment head and is used to collect the distance between the treatment head and the patient to evaluate whether there is abnormal movement of the position to be treated during ultrasound transmission.

[0018] Specifically, it also includes a display unit for displaying the guided ultrasound image obtained by the imaging unit, on which control buttons of each unit are displayed to achieve human-computer interaction, and transmit the input information obtained by the human-computer interaction to the main control unit; The main control unit obtains input information obtained from human-computer interaction, and sends the corresponding control information to the corresponding unit to implement corresponding control. At the same time, the main control unit obtains the status value and alarm value feedback from each unit, and feeds it back to the display unit for visual display.

Specifically, the connection between each unit can be realized by a USB physical interface, and each unit is connected through a USB interface / Type-C interface and a data line, a standard HID protocol layer is adopted on the physical layer, and a unique identification number of each unit is defined on the standard protocol layer, which is distinguished through a field in a device descriptor. Based on this, the present application establishes a set of standard protocols to facilitate the quick operation of the system, as shown in the following table. Figure 4 The data flow conversion mode in the present protocol also facilitates the stable operation of the system, and is specifically as follows:

[0035] The data in this protocol includes frame header, packet type, operation type, data packet number, data packet and frame tail; among them, the frame header and frame tail are represented by fixed bytes, and each receiving unit determines whether the correct data type is sent to the unit by reading the data in the frame header and frame tail; the packet type describes the type of this data, which is divided into three categories, including data writing, data reading and setting operations; the operation type is usually a sub-item of the packet type, and different operations are performed according to the packet type, including data writing, data reading and different setting operations; the data packet number is a sub-item of the operation type, which is used for later expansion; the data in the data packet is the specific content of each operation execution, such as data writing generally includes the serial number, version number, serial number and other related production information of each unit.

[0036] In the present invention, data writing is generally completed before the trolley of the present invention leaves the factory, that is, the serial number, version number, serial number and other related production information of each unit are written through the interface, so that each receiving unit can confirm through the package type during later maintenance; data reading generally includes the serial number, version number, serial number and other related production information of each unit, and also includes the status information of each unit.

[0037] In the present invention, a heartbeat mechanism is also provided, that is, the data in the data packet also includes a heartbeat packet. When reading data, each unit not only reads the written relevant production information and the status information of each unit, but also needs to read the heartbeat packet therein to confirm the online status of the sending unit. The main control unit obtains whether each unit is online or not based on this.

[0038] Through the above design, Figure 4 As shown, after the trolley of the present invention is powered on, since each unit takes a long time or requires manual operation to enter the normal working flow of the application software, each unit is in standby mode before entering the process normally, and the main control unit queries the status of each unit. If all are in standby state, the main control unit will read the information of each unit to determine whether each unit matches the main control unit. If it is found that the units match, the main control unit will send instructions to push each unit into normal working state.

[0039] Reference Figure 4In a normal working state, each unit will start a timer and be connected to the master unit, the master unit will continuously send heartbeat packet sending instructions to each unit for a short time (usually in the order of ms), after receiving the instruction, each unit will integrate each state information and the heartbeat packet into a data packet and send it to the master unit, at the same time, each unit will reset the timer and restart timing; if each unit has not received the heartbeat packet sending instruction sent by the master unit after the timer is accumulated (usually in the order of s), each unit will automatically restart and enter the standby state, waiting for the master unit to wake up; if the master unit sends the heartbeat packet sending instruction and does not receive the heartbeat packet sent by each unit within the set time, the master unit will repeatedly send the heartbeat packet sending instruction at a set interval to prevent the occasional loss of the heartbeat packet sending instruction in the transmission process, if the master unit still does not receive the heartbeat packet returned by each unit within the time defined by the timer of each unit, the master unit will restart all units on the trolley.

[0040] In the application, each unit is provided with a corresponding control chip, which can be independently controlled and operated through the control chip after being connected with the power unit.

[0041] In the application, the acoustic focal length of the focusing transducer is between 30mm-50mm, and the overall aperture is designed to be between 50mm-70mm. The circular hole of the focusing transducer can make the focal point shape of the final therapeutic ultrasound output better.

[0042] In the application, the guide image transducer protrudes 1-7mm from the emitting surface of the focusing transducer, and it is necessary to ensure that it does not affect the imaging effect and the focusing effect of the focusing transducer.

[0043] In the application, an ultrasonic sound transmission assembly is further arranged at the position of the treatment head facing the patient's affected area, which is assembled by a plastic film with a set tensile strength and a set sound transmission rate and a fixing piece for fixing the plastic film. The plastic film is used for sound transmission and is transparent or translucent in material; the fixing piece is detachably assembled with the treatment head and is used for fixing the plastic film so that it completely covers the emitting surface of the focusing transducer.

[0044] In the embodiment, the tensile strength of the plastic film in the transverse direction and the longitudinal direction is between 10Mpa-20Mpa.

[0045] In the embodiment, the plastic film is selected from materials with a Shore hardness of 70A and a sound transmission rate of 90%, such as TPU, PE or silicone material.

[0046] In the application, the plastic film can be replaced through the detachable assembly of the fixing piece and the treatment head, and in the embodiment, the plastic film is generally designed to be disposable.

[0047] In the application, the plastic film can be replaced through the detachable assembly of the fixing piece and the treatment head, and in the embodiment, the plastic film is generally designed to be disposable. Figure 2 , 3The treatment head is also equipped with a pressure sensor and a temperature sensor, both of which are immersed in the medium water used by the treatment head. The pressure sensor is used to detect the water pressure of the medium water and thus estimate the water volume; the temperature sensor is used to detect the real-time temperature of the medium water and thus estimate the temperature of the plastic film in contact with the patient's skin during treatment.

[0048] In the present invention, continue to refer to Figure 2 、 3 A distance sensor is also provided on the treatment head, which can be installed at the top of the treatment head to collect the distance between the treatment head and the patient to evaluate whether there is abnormal movement at the treatment position during ultrasound transmission.

[0049] In the present invention, an enabling button is also provided on the treatment head, which can generally be set to 1-2 buttons, which are connected to the motion control unit. When the operator, such as a doctor, presses or releases any of the buttons, the motion control unit sends a control instruction to the motion arm, causing it to enter or exit the free dragging state.

[0050] In this embodiment, an operating handle is provided on the treatment head for the operator to hold, and the enable button is provided on the operating handle, so that the operator can conveniently press the enable button while holding the operating handle.

[0051] In the present invention, the motion control unit controls the motion of each joint of the motion arm and simultaneously obtains feedback on the parameters of each joint. In the present invention, under the control of the motion control unit, after completing the positioning of the varicose vein ultrasonic treatment trolley of the present invention, the operator presses the enable button, causing the motion control unit to issue a control instruction to the motion arm, causing it to enter or exit the free dragging state. At this time, the operator can freely drag the motion arm, thereby driving the treatment head to achieve a large range of movement, so as to reach the vicinity of the patient's affected area. Afterwards, the motion control unit can be used to control the motion arm to achieve a small range of posture adjustment, so as to more precisely fine-tune the position of the treatment head.

[0052] In the present invention, Figure 5As shown, the power amplifier unit includes a monitoring and feedback unit, a control unit, a half-bridge push-pull switching unit, a series resonant unit, an isolation unit, and a load matching unit, which are connected in sequence. The monitoring and feedback unit is connected to the focusing transducer to monitor the voltage and current input to the focusing transducer and provide feedback to the control unit. The half-bridge push-pull switching unit is connected to a 0-300V DC adjustable power supply unit to adjust the input voltage to a fixed-frequency square wave. The square wave is amplified by the series resonant unit to output a higher-amplitude sine wave. After passing through the isolation unit, the sine wave is used to drive the downstream focusing transducer. The series resonant unit is composed of low-ESR capacitors and inductors wrapped around a high-saturation magnetic flux density magnetic ring. The isolation unit isolates the voltage and current signals using a 1:1 isolation transformer, while also providing voltage reduction and current amplification. The load matching unit uses a combination of inductors and capacitors to maintain the overall impedance of the downstream focusing transducer at 50Ω.

[0053] In order to ensure the safety of the system, the present invention designs a load matching unit to work in conjunction with the focusing transducer to adapt the transducer impedance to the power amplifier output.

[0054] In this embodiment, the monitoring feedback unit uses the AD8361 power detector to measure the instantaneous average value of voltage and current.

[0055] In this embodiment, the half-bridge push-pull switch tube unit uses the 2EDF7275 half-bridge driver chip and the GS66508B-MRGAN gallium nitride to control the switching of the resonant unit.

[0056] In the present invention, the water treatment unit can be designed using the structure described in the patent application number 202422312012X, the invention name of which is a water treatment device with a water bag probe, wherein the water bag probe is the treatment head in the present invention.

[0057] This invention modularizes and integrates each unit, enabling complete varicose vein surgical treatment without the need for external, independent ultrasound imaging or water supply. This invention facilitates the deployment of high-speed signal control lines. Based on high-speed communication, a unified communication protocol is customized. The data heartbeat monitoring mode extended under this communication protocol can not only meet the short-term readback requirements of a large number of feedback signals, but also ensure that the system can use the monitoring unit in good condition and reset the system in the event of a loss of control.
