Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an ultrasonic therapy device for training injuries and its operating method. Background Technology

[0002] Ultrasonic therapy devices use ultrasound waves to act on deep tissues, achieving multiple therapeutic effects, including promoting the absorption of inflammatory factors to reduce inflammation and pain, accelerating blood circulation to reduce swelling, softening scar tissue and fibrous nodules, and improving blood supply to fracture sites to accelerate healing. They are widely used in the clinical treatment of soft tissue injuries such as training injuries and fractures. Currently, when treating areas such as the arm with these devices, the main methods are either the moving method or the fixed method: the moving method requires medical personnel to hold the treatment head and move it back and forth at a speed of 2-3 cm per second, while the fixed method requires holding the treatment head and applying appropriate pressure to fix it to the affected area. Both methods rely on continuous manual operation, which can lead to significant physical exertion and high labor intensity for medical personnel when treatment is prolonged. Furthermore, manual application of force is susceptible to hand fatigue, potentially resulting in unstable pressure or pressure shifts due to slight patient movement, affecting the consistency of treatment effects. For example, Chinese patent application publication number CN116115918A discloses an ultrasound therapy system that achieves switching between two treatment modes through structures such as a base and guide ring. This eliminates manual handling, reducing the workload for medical personnel, and utilizes a clamping mechanism to automatically lay a diaphragm to prevent coupling agent adhesion and cross-infection, thus improving automation. However, this system still has room for improvement in terms of precise adjustment, stable locking, and convenient repositioning of the contact pressure between the treatment head and the treatment site. It is difficult to fully meet the higher demands for pressure controllability and ease of operation in the treatment of training injuries, and a structure that can further simplify operation and ensure stable pressure is urgently needed. Summary of the Invention

[0003] To address the aforementioned issues, an ultrasonic therapy device for training injuries and its operation method are provided. The device features an elastic connection and sliding mechanism between the treatment head and the housing, allowing for convenient pressure adjustment to suit different patient locations and individual needs. A locking component locks the target pressure, eliminating the need for continuous force application, reducing hand fatigue, and preventing pressure shifts due to unstable hand pressure or patient micro-movements, thus ensuring stable treatment pressure. An unlocking component facilitates pressure readjustment or treatment head reset. Overall, the device balances ease of operation with stable pressure, meeting the needs of training injury treatment.

[0004] To address the problems of existing technologies, this invention provides an ultrasonic therapy device for training injuries, comprising a housing and a treatment head disposed on the housing. The treatment head is located at the bottom of the housing and protrudes from the outer surface of the housing. An ultrasonic transducer for emitting therapeutic ultrasonic waves is disposed within the treatment head. The treatment head is elastically connected to the housing and can slide along the vertical direction of the housing. The treatment head can change the contact pressure on the treatment site by sliding itself. A locking component is disposed within the housing. The locking component can lock the position of the treatment head after it slides to the target position to resist the restoring force generated by the elastic connection, thereby fixing the contact pressure of the treatment head on the treatment site. An unlocking component is also disposed within the housing to release the locking component from locking the treatment head, allowing the treatment head to reset or readjust the contact pressure under elastic action.

[0005] Preferably, the locking assembly includes a rotatable sleeve disposed on the top of the housing and a ratchet coaxial with the sleeve. The top of the sleeve is provided with a pawl that matches the ratchet. The sleeve can rotate as the treatment head slides along the vertical direction of the housing.

[0006] Preferably, the treatment head is provided with an installation shaft that matches the cannula, the cannula is provided with a spiral slide rail, and the installation shaft is provided with a slider that matches the slide rail.

[0007] Preferably, the unlocking component includes multiple slide bars that can extend vertically along the housing, a ratchet is slidably disposed on the slide bars, and the ratchet can separate from and engage with the pawl by sliding along the slide bars.

[0008] Preferably, the unlocking assembly further includes two driving members that can slide relative to each other along the horizontal direction of the housing. Both driving members are elastically connected to the housing and are arranged in a mirror symmetrical manner on both sides of the ratchet. A connecting rod is provided between the driving member and the ratchet, and the two ends of the connecting rod are respectively hinged to the ratchet and the driving member.

[0009] Preferably, the treatment head includes a mounting frame and rollers. The bottom of the housing is provided with a mounting groove that matches the mounting frame. The mounting frame is slidably mounted on the mounting groove, and the rollers are rotatably mounted on the mounting frame.

[0010] Preferably, the housing is provided with a mounting hole, and a container for holding the coupling agent is installed in the mounting hole; the mounting frame is provided with a mounting box adapted to it, a connecting pipe is provided between the mounting hole and the mounting box, and the bottom of the mounting box is provided with a discharge port for releasing the coupling agent to the roller.

[0011] Preferably, the mounting box includes a mounting part fixedly connected to the connecting pipe and a movable part connected to the mounting frame and capable of sliding with the mounting frame. The discharge port is located on the movable part. The movable part is provided with two guide pillars, each of which is fitted with an elastic element. The top of the two guide pillars is connected to a mounting plate, and the mounting shaft is fixedly connected to the center of the mounting plate.

[0012] Preferably, the housing is provided with a feedback lamp that can reflect the contact pressure between the treatment head and the patient's treatment site, and the mounting shaft is provided with a sensor for detecting the distance between the end of the mounting shaft and the inner wall of the top of the sleeve. The sensor generates a signal by sensing the distance change and sends it to the feedback lamp. The feedback lamp can display different ranges of contact pressure through different lighting states.

[0013] An operating method for an ultrasound therapy device, applied to the aforementioned ultrasound therapy device for training injuries, includes the following steps:

[0014] S1. Align the treatment head with the patient's treatment area, apply external force to make the treatment head slide along the vertical direction of the shell, adjust the contact pressure of the treatment head on the treatment area to the target value, at this time the elastic connection of the treatment head generates a restoring force opposite to the sliding direction.

[0015] S2. After the treatment head slides to the target position, the position of the treatment head is locked by the locking component, so that the locking component resists the restoring force generated by the elastic connection, thereby fixing the contact pressure of the treatment head on the treatment site.

[0016] S3. Activate the ultrasonic transducer to emit ultrasonic waves, which are then used to treat the affected area via the treatment head.

[0017] S4. During or after treatment, operate the unlocking component to release the locking component from the treatment head, allowing the treatment head to reset or slide again under elastic action to adjust the contact pressure.

[0018] The advantages of this invention compared to the prior art are:

[0019] 1. This invention, through the elastic connection and sliding mechanism between the treatment head and the housing, makes it easier to adjust the contact pressure between the treatment head and the patient's treatment site, adapting to the needs of different patients' treatment sites and individuals. The locking component ensures stable locking of the treatment head once it reaches the target pressure position, eliminating the need for continuous external force from the operator, reducing hand fatigue during operation, and preventing pressure shifts caused by unstable hand force or slight patient movement, thus ensuring stable contact pressure during treatment and contributing to consistent ultrasound treatment effects. The unlocking component simplifies pressure readjustment and treatment head reset. The overall structure balances ease of operation with pressure stability, better meeting the practical needs of training injury treatment scenarios.

[0020] 2. This invention ensures a stable supply of coupling agent and convenient installation through the direct connection between the mounting hole on the shell and the container, preventing the container from falling off or leaking. The connecting tube precisely guides the coupling agent from the container to the mounting box, reducing waste or residue during transmission. The outlet is positioned directly above the roller, allowing for uniform application of the coupling agent using the roller's rotation, eliminating the need for additional manual application steps and simplifying the operation process. This is particularly suitable for scenarios requiring rapid preparation in training injury treatment. Furthermore, the compatible design of the mounting box and mounting frame ensures that the coupling agent release structure and the sliding and rolling functions of the treatment head do not interfere with each other. The overall structure is compact, guaranteeing both the continuity of coupling agent supply and the smoothness of the treatment operation, thus contributing to improved treatment efficiency and effectiveness.

[0021] 3. This invention detects pressure indirectly through distance changes, eliminating the need for complex pressure detection structures on the treatment head. It utilizes the existing mounting shaft and sleeve, simplifying the overall setup and reducing assembly difficulty. The feedback light conveys pressure information intuitively, allowing operators to quickly determine if the pressure meets treatment requirements without additional instruments. This is particularly suitable for scenarios requiring frequent pressure adjustments in training injury treatment, effectively preventing secondary injury to the patient due to excessive pressure or affecting treatment efficacy due to insufficient pressure. This improves treatment safety and ease of operation, while also enhancing the overall practicality and reliability of the equipment. Attached Figure Description

[0034] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 7 As shown: An ultrasonic therapy device for training injuries includes a housing 1 and a treatment head 2 disposed on the housing 1. The treatment head 2 is disposed at the bottom of the housing 1 and protrudes from the outer surface of the housing 1. An ultrasonic transducer 21 for emitting therapeutic ultrasonic waves is disposed inside the treatment head 2. The treatment head 2 is elastically connected to the housing 1 and can slide along the vertical direction of the housing 1. The treatment head 2 can change the contact pressure on the treatment site by sliding itself. A locking component 11 is disposed inside the housing 1. The locking component 11 can lock the position of the treatment head 2 after it slides to the target position to resist the reset force generated by the elastic connection, thereby fixing the contact pressure of the treatment head 2 on the treatment site. An unlocking component 12 is also disposed inside the housing 1 to unlock the treatment head 2 by the locking component 11, so that the treatment head 2 can reset or readjust the contact pressure under the elastic action.

[0036] Because the treatment head 2 is elastically connected to the bottom of the housing 1, and the portion of the treatment head 2 protruding from the outer surface of the housing 1 can contact the patient's treatment site, the ultrasonic transducer 21 inside the treatment head 2 can emit therapeutic ultrasonic waves, which are transmitted to the patient's treatment site through the treatment head 2. When it is necessary to adjust the contact pressure of the treatment head 2 on the patient's treatment site, pressure is applied to the housing 1, causing the treatment head 2 to slide along the vertical direction of the housing 1. During the sliding process of the treatment head 2, the elastic connection between the treatment head 2 and the housing 1 generates a restoring force opposite to the sliding direction of the treatment head 2. When the treatment head 2 slides to the target position, the locking component 11 inside the housing 1 locks the position of the treatment head 2, and by resisting the restoring force generated by the elastic connection between the treatment head 2 and the housing 1, the contact pressure of the treatment head 2 on the treatment site remains stable. If it is necessary to adjust the pressure or end the treatment, the unlocking component 12 inside the operating housing 1 can release the locking component 11 from locking the treatment head 2. At this time, the treatment head 2 can be reset under the elastic action, or by restoring the sliding of the treatment head 2, the treatment head 2 can adjust the new contact pressure with the patient's treatment site, thereby achieving flexible adjustment and stable maintenance of pressure.

[0037] The elastic connection and sliding mechanism between the treatment head 2 and the housing 1 make it easier to adjust the contact pressure between the treatment head 2 and the patient's treatment site, adapting to the needs of different patients' treatment sites and individuals. The locking component 11 ensures stable locking of the treatment head 2 after it reaches the target pressure position, eliminating the need for continuous external force from the operator, reducing hand fatigue during operation, and preventing pressure shifts caused by unstable hand force or slight patient movement, thus ensuring the stability of contact pressure during treatment and contributing to the consistency of ultrasound treatment effects. The unlocking component 12 makes pressure readjustment or resetting of the treatment head 2 simple and easy. The overall structure balances ease of operation with pressure stability, better meeting the actual needs of training injury treatment scenarios.

[0038] like Figures 3 to 8 and Figure 11 As shown: The locking assembly 11 includes a sleeve 111 rotatably disposed on the top of the housing 1 and a ratchet 112 coaxial with the sleeve 111. The top of the sleeve 111 is provided with a pawl 1111 that matches the ratchet 112. The sleeve 111 can rotate as the treatment head 2 slides along the vertical direction of the housing 1.

[0039] The sleeve 111 of the locking assembly 11 is rotatably mounted on the top of the housing 1, and the ratchet 112 is coaxially arranged with the sleeve 111. The pawl 1111 on the top of the sleeve 111 matches the ratchet 112. When the treatment head 2 slides along the vertical direction of the housing 1, the movement of the treatment head 2 will cause the sleeve 111 to rotate synchronously. During the rotation of the sleeve 111, the pawl 1111 on the top of the sleeve 111 will move together with the sleeve 111 around the axis of the ratchet 112. Due to the matching structure of the pawl 1111 and the ratchet 112, the sleeve 111 can only rotate in one direction and cannot rotate in the opposite direction, thereby limiting the rebound of the treatment head 2 in the vertical direction, realizing the locking of the position of the treatment head 2 to resist the restoring force generated by the elastic connection and ensure that the contact pressure of the treatment head 2 on the treatment site remains stable.

[0040] By arranging the rotatable sleeve 111 at the top of the housing 1 and ensuring the ratchet 112 is coaxially engaged with the sleeve 111, and utilizing the matching structure of the pawl 1111 at the top of the sleeve 111 and the ratchet 112, the sliding of the treatment head 2 can be directly converted into the directional rotation of the sleeve 111. Locking is then achieved through the unidirectional limiting characteristic of the pawl 1111 and the ratchet 112. The transmission path is direct and efficient, reducing energy loss during motion transmission and ensuring rapid and reliable locking response. The mechanical engagement of the pawl 1111 and the ratchet 112 provides strong wear resistance and structural stability. During frequent sliding adjustments and locking of the treatment head 2, it can continuously and stably achieve unidirectional rotation restriction, reliably resisting the restoring force generated by the elastic connection, ensuring that the contact pressure of the treatment head 2 on the treatment site remains stable, which is beneficial for ensuring the consistency of ultrasound treatment effects. Furthermore, the overall structure is simple and compact, with close connections between components, which not only improves the overall reliability of the device but also reduces the risk of failure due to structural complexity, making it more suitable for the actual needs of frequent operations in training injury treatment scenarios.

[0041] like Figures 3 to 8 and Figure 11 As shown: The treatment head 2 is provided with an installation shaft 22 that matches the sleeve 111. The sleeve 111 is provided with a spiral slide rail 1112. The installation shaft 22 is provided with a slider 221 that matches the slide rail 1112.

[0042] When the treatment head 2 slides vertically along the housing 1, the mounting shaft 22 moves linearly synchronously with the treatment head 2. The movement of the mounting shaft 22 drives the slider 221 to slide along the spiral slide rail 1112 on the sleeve 111. Since the slide rail 1112 is spiral, the linear motion of the slider 221 is converted into a rotational driving force on the sleeve 111, causing the sleeve 111 to rotate stably as the treatment head 2 slides. This converts the linear displacement of the treatment head 2 into the rotational motion of the sleeve 111, providing the necessary motion basis for the one-way locking function of the locking assembly 11.

[0043] By installing shaft 22, slider 221, sleeve 111, and slide rail 1112, the linear sliding motion of treatment head 2 can be precisely converted into the rotational motion of sleeve 111. This ensures smooth and seamless motion transmission of treatment head 2, guaranteeing stable linkage between the rotation of sleeve 111 and the sliding motion of treatment head 2. This provides reliable motion support for subsequent locking actions based on the rotation of sleeve 111. Furthermore, this mechanical transmission structure is simple and compact, with small clearances between components, making it less prone to wear or loosening due to frequent operation. It maintains stable transmission efficiency over long-term use, improving the structural reliability of locking assembly 11 and the entire treatment device, and better adapting to the operational needs of repeated pressure adjustments in training injury treatment scenarios.

[0044] like Figures 3 to 8 and Figure 11 As shown: The unlocking component 12 includes a plurality of slide bars 121 that can extend along the vertical direction of the housing 1. The ratchet 112 is slidably disposed on the slide bar 121, and the ratchet 112 can be separated from and engaged with the pawl 1111 by sliding along the slide bar 121.

[0045] A stable sliding guide structure is formed by multiple slide bars 121 extending vertically along the housing 1. A ratchet 112 is mounted on the slide bar 121 and can slide along the extension direction of the slide bar 121. When it is necessary to release the lock, the ratchet 112 slides along the extension direction of the slide bar 121 to move away from the pawl 1111, so that the two are disengaged, thereby releasing the restriction on the rotation of the sleeve 111. When it is necessary to restore the lock, the ratchet 112 slides in the opposite direction to move closer to the pawl 1111, so that the ratchet 112 and the pawl 1111 re-engage and reconnect, restoring the unidirectional restriction on the rotation of the sleeve 111.

[0046] The arrangement of multiple sliders 121 provides stable support for the sliding of the ratchet 112, ensuring smooth and unbiased sliding and preventing unlocking or locking failures due to sliding misalignment. Simultaneously, the ratchet 112 engages and disengages with the pawl 1111 by sliding along the sliders 121, providing direct and rapid operation and reliably switching between unlocking and locking states. This ensures the treatment head 2 can slide flexibly when adjustment is needed and lock stably when fixation is required. Furthermore, this sliding engagement structure is simple and wear-resistant, maintaining stable performance even under frequent operation, improving the reliability and lifespan of the unlocking component 12 and better adapting to the actual needs of training injury treatment scenarios.

[0047] like Figures 3 to 9 and Figure 11As shown: The unlocking component 12 also includes two driving members 122 that can slide relative to each other along the horizontal direction of the housing 1. Both driving members 122 are elastically connected to the housing 1 and are arranged in a mirror symmetrical manner on both sides of the ratchet 112. A connecting rod 1221 is provided between the driving member 122 and the ratchet 112. The two ends of the connecting rod 1221 are respectively hinged to the ratchet 112 and the driving member 122.

[0048] When unlocking is required, pressing the two drive members 122 simultaneously towards the housing 1 causes them to move closer together in the horizontal direction of the housing 1. The horizontal movement of the drive members 122 drives the movement of the connecting rod 1221 hinged to them. The connecting rod 1221 converts the movement of the drive members 122 into a driving force on the ratchet 112, thereby causing the ratchet 112 to slide along the extension direction of the slide bar 121. This causes the ratchet 112 to separate from the pawl 1111, thus releasing the lock on the treatment head 2. Because the two drive members 122 are symmetrically stressed and the connecting rod 1221 can automatically adjust its angle with the movement, it can prevent the ratchet 112 from tilting when sliding, ensuring a smooth and unobstructed separation process from the pawl 1111. When the pressure on the drive member 122 is released, the drive member 122 is reset in the opposite direction along the horizontal direction of the housing 1 under the action of the elastic connection. The ratchet 112 is driven to slide vertically in the opposite direction in sync through the connecting rod 1221, so that the ratchet 112 re-engages with the pawl 1111 and restores the locked state of the treatment head 2.

[0049] The hinged structure of two mirror-symmetrical drive components 122 and connecting rod 1221 ensures balanced force on ratchet 112, resulting in smoother sliding and preventing jamming or tilting caused by unilateral force. This ensures precise and reliable unlocking and locking actions. The elastic connection between drive component 122 and housing 1 allows for automatic reset, restoring the initial state without additional operation and improving ease of use. Simultaneously, the horizontally sliding drive component 122 and the vertically sliding ratchet 112 are linked via connecting rod 1221, efficiently converting horizontal operating force into vertical sliding of ratchet 112. This rational transmission path reduces operating effort, and the compact overall structure accommodates the limited space within housing 1, maintaining stable performance during frequent unlocking operations and further enhancing the reliability of the therapeutic device.

[0050] like Figures 3 to 9 and Figure 11 As shown: The treatment head 2 includes a mounting frame 23 and a roller 231. The bottom of the housing 1 is provided with a mounting groove 13 that matches the mounting frame 23. The mounting frame 23 is slidably mounted on the mounting groove 13, and the roller 231 is rotatably mounted on the mounting frame 23.

[0051] The mounting bracket 23 of the treatment head 2 slides into the mounting groove 13 at the bottom of the housing 1. The mounting groove 13 provides a sliding guide for the mounting bracket 23 along the vertical direction of the housing 1, ensuring that the mounting bracket 23 drives the treatment head 2 to adjust its position stably. The roller 231 is mounted on the mounting bracket 23 through a rotatable structure. When the treatment head 2 applies stable pressure to the treatment area, it pushes the housing 1 to move along the treatment area. The roller 231 can rotate in the direction of movement of the housing 1, converting the sliding friction between the treatment head 2 and the skin into rolling friction. At the same time, the sliding of the mounting bracket 23 and the mounting groove 13 can directly drive the overall adjustment of the contact pressure between the treatment head 2 and the treatment area, and cooperate with the locking component 11 to achieve pressure fixation. The rotation of the roller 231 does not affect the sliding adjustment function of the mounting bracket 23, and the two do not interfere with each other.

[0052] The sliding engagement between the mounting bracket 23 and the mounting slot 13 provides precise guidance for the pressure adjustment of the treatment head 2, preventing deviation or jamming during sliding and ensuring stable and controllable pressure adjustment. The rotatable roller 231 significantly reduces friction between the treatment head 2 and the skin when moving at the treatment site, minimizing patient discomfort, especially suitable for patients with training injuries who have sensitive skin or tense muscles, reducing resistance during treatment. Furthermore, the separate structure of the mounting bracket 23 and roller 231 facilitates individual maintenance or replacement of worn roller 231 while ensuring the overall stability of the treatment head 2. The limiting effect of the mounting slot 13 on the mounting bracket 23 also prevents structural damage caused by excessive sliding of the treatment head 2, further extending the lifespan and safety of the treatment device and better adapting to the frequent movement requirements in training injury treatment scenarios.

[0053] like Figures 1 to 7 and Figure 10 As shown: the housing 1 is provided with a mounting hole 14, and a container 141 for holding coupling agent is installed on the mounting hole 14; the mounting bracket 23 is provided with a mounting box 15 adapted to it, a connecting pipe 151 is provided between the mounting hole 14 and the mounting box 15, and the bottom of the mounting box 15 is provided with a discharge port 152 for releasing coupling agent to the roller 231.

[0054] The mounting hole 14 on the housing 1 is used to fix the container 141 containing the coupling agent, so that the container 141 forms a stable connection with the device. The container 141 and the mounting hole 14 are preferably connected by threads. The coupling agent in the container 141 can flow into the mounting box 15 on the mounting frame 23 through the connecting tube 151 between the mounting hole 14 and the mounting box 15. The mounting box 15 plays a role in temporarily storing and guiding the coupling agent. When the treatment head 2 is working, the discharge port 152 at the bottom of the mounting box 15 accurately releases the coupling agent onto the surface of the roller 231. As the roller 231 rotates at the patient's treatment site, the coupling agent is evenly applied to the skin surface, providing a medium for the transmission of ultrasound.

[0055] The direct connection between the mounting hole 14 and the container 141 ensures a stable supply of coupling agent and facilitates installation, preventing the container 141 from falling off or leaking. The connecting tube 151 precisely guides the coupling agent from the container 141 to the mounting box 15, reducing waste or residue during transmission. The outlet 152 is positioned above the roller 231, allowing for uniform application of the coupling agent through the rotation of the roller 231, eliminating the need for additional manual application steps and simplifying the operation process. This is especially suitable for scenarios requiring rapid preparation in training injury treatment. Simultaneously, the compatible design of the mounting box 15 and the mounting frame 23 ensures that the coupling agent release structure and the sliding and rolling functions of the treatment head 2 do not interfere with each other. The overall structure is compact, ensuring both the continuity of coupling agent supply and the smoothness of the treatment operation, thus contributing to improved treatment efficiency and effectiveness.

[0056] like Figures 3 to 10 As shown: The mounting box 15 includes a mounting part 1511 fixedly connected to the connecting pipe 151 and a moving part 1521 connected to the mounting frame 23 and capable of sliding with the mounting frame 23. The discharge port 152 is provided on the moving part 1521. The moving part 1521 is provided with two guide posts 1522. Each of the two guide posts 1522 is fitted with an elastic element 1523. The top of the two guide posts 1522 is connected to a mounting plate 1524. The mounting shaft 22 is fixedly connected to the center of the mounting plate 1524.

[0057] The mounting box 15 is fixed to the connecting pipe 151 via the mounting part 1511 to ensure a stable delivery path for the coupling agent and prevent it from shifting as the mounting frame 23 slides. The connection between the moving part 1521 and the mounting frame 23 allows the moving part 1521 to slide synchronously with the mounting frame 23 along the vertical direction of the housing 1, preventing the mounting frame 23 from pulling or damaging the mounting box 15 when it slides. At the same time, it ensures that the outlet 152 on the moving part 1521 can always accurately release the coupling agent to the roller 231. When the treatment head 2 is subjected to pressure and slides vertically along the housing 1, the mounting bracket 23 will drive the moving part 1521 to move synchronously. The two guide posts 1522 on the moving part 1521 move together with the moving part 1521, causing the elastic element 1523 sleeved on the guide posts 1522 to deform. Since the mounting shaft 22 is fixed in the center of the mounting plate 1524 at the top of the two guide posts 1522, the movement of the guide posts 1522 directly drives the mounting shaft 22 to move synchronously in a vertical linear motion. When the mounting shaft 22 moves, the slider 221 on the mounting shaft 22 will move along the spiral slide rail 1 on the sleeve 111. When the slide rail 1112 slides, the linear motion of the slider 221 is converted into a rotational driving force on the sleeve 111 due to the spiral direction of the slide rail 1112, which ultimately drives the sleeve 111 to rotate stably. At the same time, the restoring force generated by the deformation of the elastic element 1523 is transmitted to the mounting shaft 22 through the guide post 1522 and the mounting plate 1524, providing a reverse support force for the treatment head 2 and realizing the elastic connection between the treatment head 2 and the housing 1. When the locking assembly 11 is unlocked, the restoring force of the elastic element 1523 will drive the mounting shaft 22, the guide post 1522, the moving part 1521 and the mounting bracket 23 to retract, thereby restoring the treatment head 2.

[0058] The design of the moving part 1521 and the mounting part 1511 transforms the mounting box 15 into a retractable mounting cavity. This ensures the stability of the coupling agent delivery while accommodating the sliding requirements of the mounting bracket 23, preventing interference or damage between structures and ensuring uninterrupted coupling agent supply. The cooperation between the guide post 1522 and the elastic element 1523 not only provides precise guidance for the sliding of the treatment head 2, preventing slippage, but also enables the automatic retraction of the treatment head 2 through elastic restoring force. Simultaneously, it provides a stable linear motion basis for the mounting shaft 22 to drive the sleeve 111 to rotate, making the conversion from linear motion to rotational motion smoother. Furthermore, the functions of each component are closely interconnected, integrating the coupling agent supply, the elastic connection of the treatment head 2, and the rotational transmission of the sleeve 111. This eliminates the need for additional independent structures, simplifying overall assembly, improving the structural integration and reliability of the equipment, and better adapting to the operational requirements of repeated pressure adjustments in training injury treatment scenarios.

[0059] like Figures 1 to 8 and Figure 10As shown: The housing 1 is provided with a feedback lamp 16 that can reflect the contact pressure between the treatment head 2 and the patient's treatment site. The mounting shaft 22 is provided with a sensor 222 for detecting the distance between the end of the mounting shaft 22 and the inner wall of the top of the sleeve 111. The sensor 222 generates a signal by sensing the change in distance and sends it to the feedback lamp 16. The feedback lamp 16 can display different ranges of contact pressure through different lighting states.

[0060] When the treatment head 2 contacts the patient's treatment site and generates pressure, the treatment head 2 slides vertically along the housing 1, causing the associated mounting shaft 22 to move synchronously. During the movement of the mounting shaft 22, the distance between the end of the mounting shaft 22 and the inner wall of the top of the sleeve 111 changes accordingly. The sensor 222 on the mounting shaft 22 senses the distance change in real time and converts the distance signal into an electrical signal, which is then sent to the feedback lamp 16 on the housing 1. Since the contact pressure between the treatment head 2 and the treatment site is positively correlated with the displacement of the mounting shaft 22, that is, the greater the pressure of the treatment head 2, the greater the displacement of the mounting shaft 22, and the smaller the distance between the end of the mounting shaft 22 and the inner wall of the top of the sleeve 111, the feedback lamp 16 displays different lighting states according to the received electrical signal, such as different colors or flashing patterns. Each lighting state corresponds to a specific range of contact pressure, thus providing intuitive feedback on the current pressure status.

[0061] Sensor 222 is directly mounted on mounting shaft 22 and moves synchronously with it, accurately capturing changes in the distance between the end of mounting shaft 22 and the inner wall of the top of sleeve 111. This avoids detection lag or errors caused by the fixed installation of sensor 222, thus more accurately reflecting the actual contact pressure of treatment head 2. By indirectly detecting pressure through distance changes, there is no need to add a complex pressure detection structure to treatment head 2. The existing cooperation between mounting shaft 22 and sleeve 111 is utilized, simplifying the overall setup and reducing assembly difficulty. Feedback light 16 transmits pressure information with a clear illumination status. Operators can quickly determine whether the pressure meets treatment requirements without the need for additional instruments to read data. This is especially suitable for scenarios where pressure is frequently adjusted in training injury treatment, effectively preventing secondary injury to the patient due to excessive pressure or affecting treatment effectiveness due to insufficient pressure. This improves the safety and ease of operation of treatment, while also enhancing the overall practicality and reliability of the equipment.

[0062] like Figures 1 to 7 The following is an example of an operating method for an ultrasonic therapy device, applied to the aforementioned ultrasonic therapy device for training injuries:

[0063] S1. Align the treatment head 2 with the patient's treatment site, apply external force to make the treatment head 2 slide along the vertical direction of the housing 1, adjust the contact pressure of the treatment head 2 on the treatment site to the target value, at this time the elastic connection of the treatment head 2 generates a restoring force opposite to the sliding direction.

[0064] S2. After the treatment head 2 slides to the target position, the position of the treatment head 2 is locked by the locking component 11, so that the locking component 11 resists the restoring force generated by the elastic connection, thereby fixing the contact pressure of the treatment head 2 on the treatment site.

[0065] S3. Start the ultrasonic transducer 21 to emit ultrasonic waves, which are then used to treat the treatment area through the treatment head 2.

[0066] S4. During or after treatment, operate the unlocking component 12 to release the locking component 11 from locking the treatment head 2, so that the treatment head 2 can be reset or slide again under elastic action to adjust the contact pressure.

[0067] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
