Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment, and in particular to a transducer assembly and a modular focused ultrasound head-mounted device. Background Art

[0002] Major brain diseases and neurological diseases have always been a huge challenge for the medical community, especially the treatment of brain tumors, which is a major challenge for modern medicine. Although traditional treatments such as surgical resection, radiotherapy and chemotherapy are effective, they have significant limitations: surgery has high risks and is prone to recurrence, and radiotherapy and chemotherapy have serious side effects and limited effects. In recent years, ultrasound technology has attracted much attention due to its non-invasiveness and high efficiency.

[0003] Tumor treatment field (TTF) devices use alternating electric fields to inhibit the ability of cancer cells to divide, and have shown good results in treating brain tumors, especially glioblastoma. However, existing TTF devices have problems such as low wireless energy transmission efficiency, long-term wearing of electrode patches that can easily cause skin inflammation, and high device prices, resulting in unstable treatment effects, poor wearing comfort, and high maintenance costs. In order to improve the effectiveness of the device and patient experience, new technical solutions need to be developed urgently.

[0004] In recent years, Sun Yat-sen University has developed a brain-implanted tumor treatment electric field medical device called UP-TTD, which overcomes the shortcomings of traditional TTF devices, such as low transmission efficiency, low safety, rough spatial resolution, and easy to cause skin inflammation. It uses an external device to emit ultrasound waves of a specific frequency to generate friction nanoelectricity and generate an alternating electric field. When the frequency of the alternating electric field reaches 100-300KHz like the traditional TTF, it can effectively inhibit the proliferation of cancer cells.

[0005] With the advancement of science and technology and the continuous increase in medical needs, the market demand for new medical equipment is becoming stronger and stronger. Especially for brain tumor treatment equipment, how to improve the patient's comfort and the convenience of equipment use while ensuring the treatment effect is the key direction of technology research and development. Summary of the invention

[0006] In view of this, the present invention provides a transducer assembly and a modular focused ultrasound head-mounted device to improve patient comfort and ease of use of the device.

[0007] In a first aspect, the present invention provides a transducer assembly, comprising:

[0008] a central transducer mount having a mounting end;

[0009] A plurality of blades, all of which are hinged to the mounting end and distributed circumferentially along the mounting end;

[0010] A transducer is provided on any of the blades, and all of the transducers are focused toward the mounting end;

[0011] A biasing member is fixed between the central transducer seat and all the blades, and the biasing member has a biasing force forcing the blades to rotate relative to the mounting end, so as to drive the transducers to gather toward the mounting end through the blades.

[0012] When the above structure is in use, the mounting end of the central transducer seat faces the patient's head, and the transducer on the blade is in contact with the surface of the patient's head. The transducer emits ultrasonic waves of a specific frequency to generate frictional nanoelectricity and generate an alternating electric field, which inhibits the division ability of cancer cells. Since the biasing member is fixed between the central transducer seat and all the blades, when the transducer is pressed against the surface of the patient's head, the blades can rotate relative to the central transducer seat until the direction of the transducer and the contact surface angle are placed at a predetermined position to ensure a stable focusing effect. At this time, the blades and the transducer are always in contact with the patient's head under the biasing force of the biasing member. This design can improve the convenience of use of the device, and the biasing force of the biasing member can ensure that the rotation angle of the blade is adjustable, so that the transducer can fit the scalp closely to prevent the existence of a gap between the transducer and the head, thereby reducing ultrasonic energy loss, and automatically adjusting according to different head shapes to improve wearing comfort.

[0013] In an optional embodiment, the biasing member includes a central fixing portion and a biasing portion fixed on a peripheral side of the central fixing portion and extending outwardly, the central fixing portion is connected to the central transducer seat, and an end of the biasing portion extending outwardly is connected to the blade.

[0014] In an optional embodiment, all the biasing portions are bent toward the same side of the central fixing portion to force the transducer to have an initial position focused toward the mounting end.

[0015] In the above structure, at the connection between the biasing part and the central fixing part, all the biasing parts are bent toward the upper side of the central fixing part, so that when the biasing part is not subjected to force, the biasing part can maintain the initial position focused toward the mounting end. After the biasing part is installed between the central transducer seat and the blade, when the blade and the transducer thereon are not subjected to force, the blade can always be in the initial position focused toward the mounting end of the central transducer seat under the action of the biasing part. When in use, the blade in the initial position can facilitate the transducer thereon to contact the patient's head, and automatically adjust according to the different shapes of the head to improve the wearing comfort.

[0016] In an optional embodiment, any one of the blades is hinged to the mounting end via an angle limiter, and the angle limiter is configured to limit a rotation angle of the blade relative to the mounting end.

[0017] In an optional implementation, any of the transducers is covered with a silicone sleeve.

[0018] In the above structure, the transducer is covered with a silicone sleeve, which is arranged on the outside of the transducer to protect and fix it. Furthermore, adding a silicone layer on the contact surface of the transducer, i.e. the above silicone sleeve, can evenly distribute the pressure and improve the wearing comfort, while reducing the gap between the transducer and the patient's head and ensuring the transducer is fixed in the direction, achieving the best focusing effect.

[0019] In an optional embodiment, a plurality of the blades are distributed at equal intervals around the mounting end.

[0020] In an optional embodiment, the transducer assembly further comprises a guide connecting rod, which is fixed to the fixed end of the central transducer seat by magnets arranged on both ends;

[0021] The guide connecting rod and the fixed end of the central transducer seat are both provided with positioning holes and pins that are adapted to each other.

[0022] In the above structure, in order to facilitate the rapid installation and removal of the transducer assembly, the guide connecting rod and the fixed end of the central transducer seat are both provided with magnets, such as nepheline magnets, and the guide connecting rod is fixed to the central transducer seat by the magnetic attraction of the magnets provided at the guide connecting rod and the fixed end of the central transducer seat. The magnet can be fixed to the guide connecting rod or the fixed end of the central transducer seat by glue.

[0023] Furthermore, in order to ensure that the central transducer seat and the blades and transducers thereon can be in the correct position without deflection, the present invention provides mutually adapted positioning holes and pins on the guide connecting rod and the fixed end of the central transducer seat. The guide connecting rod is provided with positioning holes and pins arranged at intervals, and the fixed end of the central transducer seat is also provided with positioning holes and pins at intervals. During installation, the pins at the fixed end of the central transducer seat are inserted into the positioning holes on the guide connecting rod, and at the same time, the pins on the guide connecting rod are also inserted into the positioning holes at the fixed end of the central transducer seat to complete the positioning of the central transducer seat.

[0024] In an optional embodiment, the transducer assembly further comprises a special-shaped bolt, wherein a cavity with an open end is provided inside the special-shaped bolt, and an elastic member is placed inside the cavity;

[0025] The guide connecting rod is slidably arranged in the cavity at one end away from the central transducer seat and abuts against the elastic member. The inner wall of the cavity is provided with a sliding groove adapted to the protrusion at the end of the guide connecting rod, and the sliding groove is configured to limit the rotation of the guide connecting rod.

[0026] The above structure is provided with a special-shaped bolt so as to connect the transducer assembly to the head-mounted main frame through the special-shaped bolt. A cavity with an open end is provided inside the special-shaped bolt, and an elastic member is placed inside the cavity. The elastic member is a spring, and the lower end of the guide connecting rod is placed inside the cavity inside the special-shaped bolt, and the lower end of the guide connecting rod is in contact with the elastic member. When in use, the entire system can achieve a certain range of mobile buffering adjustment in the vertical direction to adapt to the pressure requirements, increase a certain buffering effect, and improve the stability and adaptability of the device during use.

[0027] In a second aspect, the present invention further provides a modular focused ultrasound head-mounted device, comprising:

[0028] A head-mounted main frame, on which a plurality of fixing parts are fixed;

[0029] A plurality of the above-mentioned transducer assemblies, wherein the transducer assemblies are connected to the fixing portion, and the central transducer seat mounting end is adapted to face toward the human body;

[0030] Wherein, the transducer assembly is configured to be fixed to the fixing parts at different positions so as to adjust the focusing position of the transducer.

[0031] The above structure, based on the head-mounted characteristics, realizes modular design through the combination of the head-mounted main frame and the transducer assembly. The transducer assembly can be docked and installed on the head-mounted main frame as needed. The transducer assembly can achieve adaptive ultrasonic focusing with adjustable force. The transducer assembly can be adjusted to a certain extent to adapt to different head shapes, enhance the portability of wearing, and reduce the discomfort when the device is coupled with the skull. By studying the relationship between the transducer orientation and the contact surface angle, the focusing effect is ensured to be stable. By optimizing the device structure and focusing method, a general array layout and model design are established.

[0032] In an optional embodiment, the modular focused ultrasound head-mounted device further includes an additional fixing member, wherein the additional fixing member is connected to the head-mounted main body frame;

[0033] The additional fixing member is configured to provide an additional fixing position for the transducer assembly on the head-mounted body frame.

Since the biasing member is fixed between the central transducer seat and all the blades, when the transducer is pressed against the surface of the patient's head, the blades can rotate relative to the central transducer seat until the direction of the transducer and the contact surface angle are placed at a predetermined position to ensure a stable focusing effect.

[0067] Example 1

[0068] Major brain diseases and neurological diseases have always been a huge challenge for the medical community, especially the treatment of brain tumors, which is a major challenge for modern medicine. Although traditional treatments such as surgical resection, radiotherapy and chemotherapy are effective, they have significant limitations: surgery has high risks and is prone to recurrence, and radiotherapy and chemotherapy have serious side effects and limited effects. In recent years, ultrasound technology has attracted much attention due to its non-invasiveness and high efficiency.

[0069] Tumor treatment field (TTF) devices use alternating electric fields to inhibit the ability of cancer cells to divide, and have shown good results in treating brain tumors, especially glioblastoma. However, existing TTF devices have problems such as low wireless energy transmission efficiency, long-term wearing of electrode patches that can easily cause skin inflammation, and high device prices, resulting in unstable treatment effects, poor wearing comfort, and high maintenance costs. In order to improve the effectiveness of the device and patient experience, new technical solutions need to be developed urgently.

[0070] In recent years, Sun Yat-sen University has developed a brain-implanted tumor treatment electric field medical device called UP-TTD, which overcomes the shortcomings of traditional TTF devices, such as low transmission efficiency, low safety, rough spatial resolution, and easy to cause skin inflammation. It uses an external device to emit ultrasound waves of a specific frequency to generate friction nanoelectricity and generate an alternating electric field. When the frequency of the alternating electric field reaches 100-300KHz like the traditional TTF, it can effectively inhibit the proliferation of cancer cells.

[0071] With the advancement of science and technology and the continuous increase in medical needs, the market demand for new medical equipment is becoming stronger and stronger. Especially for brain tumor treatment equipment, how to improve the patient's comfort and the convenience of equipment use while ensuring the treatment effect is the key direction of technology research and development.

[0072] To this end, this embodiment provides a transducer assembly, such as Figures 1 to 3 As shown, it includes a central transducer seat 1, blades 2, a transducer 3, a biasing member 4, an angle limiting member 5, a guide connecting rod 6, a special-shaped bolt 7 and an elastic member 8.

[0073] In this embodiment, the central transducer seat 1 has a mounting end, all blades 2 are hinged to the mounting end and distributed circumferentially along the mounting end, a transducer 3 is provided on any blade 2, all transducers 3 are focused toward the mounting end, and a biasing member 4 is fixed between the central transducer seat 1 and all blades 2. The biasing member 4 has a biasing force forcing the blades 2 to rotate relative to the mounting end, so as to drive the transducers 3 to gather toward the mounting end through the blades 2.

[0074] like Figure 1 In the embodiment shown, the central transducer seat 1 is cylindrical, and its upper end is divided into the mounting end set in this embodiment. There are four blades 2, and the four blades 2 are hinged to the mounting end of the central transducer seat 1 and distributed along the circumference of the mounting end. The outer end of the blade 2 is divided into a disc shape, and the transducer 3 is fixed on the disc-shaped outer end of the blade 2. The width of the inner end part of the blade 2 is reduced for hinge connection with the circumference of the mounting end, so that the blade 2 can rotate relative to the central transducer seat 1 to change the position of the transducer 3, thereby realizing the change of the focusing position of the transducer 3. The biasing member 4 is fixed between the central transducer seat 1 and all the blades 2. In this embodiment, the biasing member 4 has a biasing force that forces the blade 2 to rotate relative to the mounting end. Under the action of this biasing force, the blade 2 can drive the transducer 3 to gather toward the mounting end.

[0075] When in use, the mounting end of the central transducer seat 1 faces the patient's head, and the transducer 3 on the blade 2 fits the surface of the patient's head. The transducer 3 emits ultrasonic waves of a specific frequency to generate friction nanoelectricity, generating an alternating electric field, and inhibiting the division ability of cancer cells through the alternating electric field. Since the biasing member 4 is fixed between the central transducer seat 1 and all the blades 2, when the transducer 3 is pressed against the surface of the patient's head, the blade 2 can rotate relative to the central transducer seat 1 until the orientation and contact surface angle of the transducer 3 are placed at a predetermined position to ensure a stable focusing effect. At this time, the blade 2 and the transducer 3 are always in contact with the patient's head under the biasing force of the biasing member 4. This design can improve the convenience of use of the device. The biasing force of the biasing member 4 can ensure that the rotation angle of the blade 2 is adjustable, so that the transducer 3 can fit the scalp closely, prevent the existence of a gap between the transducer 3 and the head, thereby reducing the ultrasonic energy loss, and automatically adjust according to the different shapes of the head to improve the wearing comfort.

[0076] In order to further improve the comfort of the patient, in this embodiment, a silicone sleeve is provided on the transducer 3, which can play a role of protection and fixation. Furthermore, adding a silicone layer on the contact surface of the transducer 3, i.e., the above-mentioned silicone sleeve, can evenly distribute the pressure, improve the wearing comfort, and at the same time achieve the effect of reducing the gap between the transducer 3 and the patient's head and ensuring the transducer 3 is fixed in the direction, so as to achieve the best focusing effect.

[0077] In this embodiment, the biasing member 4 includes a central fixing portion and a biasing portion fixed on the periphery of the central fixing portion and extending outwardly. The central fixing portion is connected to the central transducer seat 1 , and one end of the biasing portion extending outwardly is connected to the blade 2 .

[0078] Specific as Figure 2 and Figure 3 As shown, the central fixing part is disc-shaped and is provided with a plurality of through holes. The central fixing part is fixed to the bottom of the central transducer seat 1. The number of biasing parts is consistent with the number of blades 2. Four biasing parts are also provided. The four biasing parts are all fixed to the side of the central fixing part. A blade 2 is fixed to the other end of each of the four biasing parts. The four biasing parts are made of elastic material and are used to provide a biasing force so that the blades 2 and the transducer 3 are always in contact with the patient's head.

[0079] In this embodiment, if Figure 2 As shown, the biasing part is arranged at the bottom of the blade 2, and the blade 2 is provided with a latch hole at its bottom, and the end of the biasing part is inserted into the latch hole at the bottom of the blade 2 to achieve the fixation of the biasing part and the blade 2. In order to prevent the biasing part from being separated from the latch hole during the rotation of the blade 2, the blade 2 should have a sufficient length to extend into the latch hole.

[0080] In this embodiment, if Figure 3As shown, all biasing portions are bent toward the same side of the central fixing portion to force the transducer 3 to have an initial position focused toward the mounting end.

[0081] like Figure 3 As shown, at the connection between the biasing part and the central fixing part, all the biasing parts are bent toward the upper side of the central fixing part, so that when the biasing part 4 is not subjected to force, the biasing part 4 can be kept in the state of Figure 3 After the biasing member 4 is installed between the central transducer seat 1 and the blade 2, when the blade 2 and the transducer 3 thereon are not subjected to force, the blade 2 can always be in the state shown under the action of the biasing member 4. Figure 1 The initial position of focusing toward the mounting end of the central transducer seat 1 is shown in FIG. When in use, the blade 2 in the initial position can facilitate the transducer 3 thereon to contact the patient's head and automatically adjust according to the different shapes of the head to improve the wearing comfort.

[0082] In this embodiment, any blade 2 is hinged to the mounting end via an angle limiter 5, and the angle limiter 5 is configured to limit the rotation angle of the blade 2 relative to the mounting end.

[0083] During use, an angle limiter 5 is provided between the blade 2 and the central transducer seat 1 to enable the blade 2 to rotate relative to the central transducer seat 1. In this embodiment, the angle limiter 5 is a stainless steel hinge to ensure the angle adjustment range of the blade 2.

[0084] In this embodiment, four blades 2 are evenly spaced and distributed around the mounting end. In other embodiments, the number of blades 2 can also be adjusted according to the situation, such as three, five or six.

[0085] In this embodiment, the guide connecting rod 6 and the fixed end of the central transducer seat 1 are fixed by magnets arranged on both; the guide connecting rod 6 and the fixed end of the central transducer seat 1 are both provided with positioning holes and pins that are adapted to each other.

[0086] like Figures 1 to 3 As shown, the guide connecting rod 6 is fixed to the fixed end of the central transducer seat 1, and this fixed end is the lower end of the central transducer seat 1 in the figure. In this embodiment, in order to facilitate the rapid installation and disassembly of the transducer assembly, the guide connecting rod 6 and the fixed end of the central transducer seat 1 are both provided with magnets, such as nebulium magnets, and the guide connecting rod 6 is fixed to the central transducer seat 1 by the magnetic attraction of the magnets provided at the fixed ends of the guide connecting rod 6 and the central transducer seat 1. The magnet can be fixed to the guide connecting rod 6 and the fixed end of the central transducer seat 1 by glue.

[0087] Furthermore, in order to ensure that the central transducer seat 1 and the blades 2 and transducer 3 thereon are in the correct position without deflection, in this embodiment, the guide connecting rod 6 and the fixed end of the central transducer seat 1 are provided with mutually matching positioning holes and pins. Figure 3 As shown, the guide connecting rod 6 is provided with positioning holes and pins arranged at intervals, and the fixed end of the central transducer seat 1 is also provided with positioning holes and pins at intervals. During installation, the pin at the fixed end of the central transducer seat 1 is inserted into the positioning hole on the guide connecting rod 6, and the pin on the guide connecting rod 6 is also inserted into the positioning hole at the fixed end of the central transducer seat 1, so as to complete the positioning of the central transducer seat 1.

[0088] like Figure 3 As shown, the biasing member 4 is provided with a plurality of through holes. When the biasing member 4 is installed, the biasing member 4 is placed between the fixed end of the central transducer seat 1 and the guide connecting rod 6, and the pins on the fixed end of the central transducer seat 1 and the guide connecting rod 6 are inserted into the through holes on the biasing member 4, and the biasing member 4 is fixed by squeezing the fixed end of the central transducer seat 1 and the guide connecting rod 6.

[0089] In this embodiment, if Figure 2 and Figure 3 As shown, a cavity with an open end is provided inside the special-shaped bolt 7, and an elastic member 8 is placed inside the cavity; the guide connecting rod 6 is slidably set in the cavity at one end away from the central transducer seat 1 and abuts against the elastic member 8, and a sliding groove adapted to the protrusion at the end of the guide connecting rod 6 is provided on the inner wall of the cavity, and the sliding groove is configured to limit the rotation of the guide connecting rod 6.

[0090] By providing the special-shaped bolt 7, the transducer assembly is connected to the head-mounted main frame 9 through the special-shaped bolt 7. Figure 2 and Figure 3 As shown, a cavity with an open end is provided inside the special-shaped bolt 7, and an elastic member 8 is placed inside the cavity. The elastic member 8 is a spring, and the lower end of the guide connecting rod 6 is placed inside the cavity inside the special-shaped bolt 7, and the lower end of the guide connecting rod 6 is in contact with the elastic member 8. When in use, the entire system can achieve a certain range of mobile buffering adjustment in the vertical direction to adapt to the pressure requirements, increase a certain buffering effect, and improve the stability and adaptability of the equipment during use. The spring uses a spring with a wire diameter of 0.7mm, an outer diameter of 1.0mm, and a total length of 25mm. It has a certain plasticity and ensures support, so that the spring can maintain its shape and function in different use environments, further enhancing the applicability and reliability of the entire transducer assembly.

[0091] Furthermore, in order to prevent the guide connecting rod 6 from rotating when moving in the internal cavity of the special-shaped bolt 7, a sliding groove is provided on the inner wall of the cavity in this embodiment, and the sliding groove is opened along the axial direction of the guide connecting rod 6. Correspondingly, a protrusion is provided at the end of the guide connecting rod 6. When in use, the protrusion at the end of the guide connecting rod 6 is slidably set inside the sliding groove of the inner wall of the cavity. This design can prevent the guide connecting rod 6 from rotating when moving in the internal cavity of the special-shaped bolt 7 through the cooperation of the sliding groove and the protrusion.

[0092] Furthermore, in order to prevent the guide connecting rod 6 from falling out of the cavity when it moves in the inner cavity of the special-shaped bolt 7. Figure 2 As shown, the inner wall of the open end of the cavity inside the special-shaped bolt 7 is provided with an annular limiting wall, and the corresponding end of the guide connecting rod 6 inside the cavity is provided with an annular protrusion, and the outer diameter of the annular protrusion is larger than the inner diameter of the annular limiting wall, thereby preventing the guide connecting rod 6 from falling out of the cavity when moving in the cavity inside the special-shaped bolt 7. At the same time, in order to facilitate the placement of the annular protrusion at the end of the guide connecting rod 6 in the cavity inside the special-shaped bolt 7, the annular protrusion can be made of a flexible material.

[0093] The transducer assembly provided in this embodiment is installed as follows:

[0094] First, install the transducer 3 on the blade 2 to ensure that it is firmly fixed, and then connect the blade 2 to the central transducer seat 1 through the angle limiter 5 to adjust the angle of the blade 2; then insert one end of the biasing member 4 into the pin hole of the blade 2, and fix the other end on the central transducer seat 1; then insert the pin shaft at the fixed end of the central transducer seat 1 into the positioning hole on the guide connecting rod 6, and at the same time, the pin shaft on the guide connecting rod 6 is also inserted into the positioning hole at the fixed end of the central transducer seat 1 to complete the positioning of the central transducer seat 1, and fix it by adsorption through the neodymium magnet; then connect the special-shaped bolt 7 to the guide connecting rod 6, and limit it through the annular limiting wall set on the inner wall of the open end of the internal cavity of the special-shaped bolt 7.

[0095] Example 2

[0096] The present embodiment provides a modular focused ultrasound head-mounted device, comprising a head-mounted main frame 9 and several transducer assemblies in Embodiment 1, wherein the transducer assembly is connected to a fixing portion 10, and the mounting end of a central transducer seat 1 is adapted to face toward a human body; wherein the transducer assembly is configured to be fixed to the fixing portion 10 at different positions to adjust the focusing position of the transducer 3.

[0097] like Figure 4 and Figure 5 As shown, the head-mounted main frame 9 is designed to fit the human head, and a plurality of fixing parts 10 are fixed thereon, and the fixing parts 10 are used to fix the transducer assembly in Example 1. Figure 5 As shown, Figure 5 It is a top view of the head-mounted main frame 9. After the transducer assembly is fixed to the fixing part 10, the mounting end of the central transducer seat 1 of the transducer assembly is adapted to face the human body so that the transducer 3 in the transducer assembly can fit the patient's head.

[0098] In this embodiment, the fixing portion 10 is a hexagonal rounded stepped hole. This embodiment adopts a hexagonal rounded hole design, which is not only beautiful but also has practical application value. The hexagonal shape provides precise positioning for the transducer 3 seat, ensuring that each transducer 3 can be accurately aligned to the predetermined position, thereby maximizing the accuracy and efficiency of the focusing effect. The transducer assembly can be assembled through the rounded hole with the heterosexual stepped nut. The threaded design allows the main transducer assembly to be adjusted up and down, and the installation force of the transducer 3 is adjusted to meet the needs of different user groups and ensure the versatility of the device.

[0099] like Figure 4 and Figure 5 As shown, the four transducer assemblies are assembled with each other through the fixing part 10 to achieve focusing from four different directions. The design is based on the 10-20 international system to locate the modular transducer 3 on the entire head-mounted main frame 9 and install the brain area. A large number of fixing parts 10 are cleverly designed. These fixing parts 10 are distributed in different directions of the head-mounted main frame 9 to provide a multi-point, highly flexible focusing platform. This layout allows the transducer 3 array to be adjusted more flexibly to adapt to different focusing requirements, thereby providing more accurate and greater intensity ultrasonic focusing capabilities in a wide range of applications.

[0100] In this embodiment, if Figure 6 As shown, the modular focused ultrasound head-mounted device also includes an additional fixing member 11, which is connected to the head-mounted main frame 9; the additional fixing member 11 is configured to provide an additional fixing position for the transducer assembly on the head-mounted main frame 9.

[0101] In the case where the fixing part 10 on the head-mounted main frame 9 is insufficient or interferes, an additional fixing part 11 is designed to fill the gap and provide additional points for assembly, which can ensure that additional points are provided for assembly when the points are insufficient. In this embodiment, Velcro is used to fix the additional fixing part 11 to the head-mounted main frame 9, which is flexible and realizes a variety of assembly methods. Among them, the additional fixing part 11 can be a nut that is compatible with the special-shaped bolt 7.

[0102] like Figure 7 As shown, a gap is designed at the bottom edge of the head-mounted main frame 9 for inserting a connecting strap to ensure that the device can be stably worn on the user's head. It can be adjusted to adapt to different head shapes and sizes to ensure comfort and stability of the device during use.

[0103] The modular focused ultrasound head-mounted device provided in this embodiment is based on the head-mounted characteristics and realizes modular design through the combination of the head-mounted main frame 9 and the transducer assembly. The transducer assembly can be docked and installed on the head-mounted main frame 9 as required. The transducer assembly can achieve adaptive ultrasonic focusing with adjustable force. The transducer assembly can be adjusted to a certain extent to adapt to different head shapes, enhance the portability of wearing, and reduce the discomfort when the device is coupled with the skull. By studying the relationship between the orientation of the transducer 3 and the contact surface angle, the focusing effect is ensured to be stable, and by optimizing the device structure and focusing method, a general array layout and model design are established.

[0104] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
