Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of medical devices, and in particular, to a novel ankle joint ultrasonic stretching therapeutic device. Background Art

[0002] In the medical field, the treatment of ankle joint diseases has always been an important topic. Traditional ultrasonic stretching treatment equipment has many shortcomings and is difficult to meet modern medical needs.

[0003] Early ultrasonic stretch therapy devices were mostly handheld, and doctors had to hold the device for a long time when operating it, which could easily cause hand fatigue and affect the stability and sustainability of the treatment. In addition, during the operation, the doctor's hand shaking or mistakes may cause the treatment probe to deviate from the position, affecting the treatment effect. When treating ankle ligament injuries, if the treatment probe is not positioned accurately, the ultrasonic energy cannot act accurately on the damaged area, making it difficult to effectively promote local blood circulation and tissue repair.

[0004] Handheld ultrasonic stretching therapy devices usually only have a single treatment probe, which makes it difficult to fully cover the lesion area of ​​the ankle joint. For complex ankle joint diseases, such as arthritis, a single probe cannot fully treat multiple joint surfaces and surrounding tissues, resulting in limited treatment effects and failure to meet the needs of precision treatment. At the same time, in the prior art, when ultrasonic stretching therapy devices and stretching therapy for patients are performed simultaneously, the treatment effect is poor, which makes it difficult for medical staff to operate and the treatment effect on patients is poor.

[0005] With the development of medical technology and the improvement of people's demand for health, there is an urgent need for a new type of ankle joint ultrasonic stretching therapy device to address the shortcomings of traditional equipment and improve treatment effects, efficiency and patients' treatment experience.

[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0026] like Figure 1~Figure 4 As shown, it shows a new type of ankle joint ultrasonic stretching therapeutic device in an embodiment of the present disclosure, including a fixing sleeve 1, a flexible sheath 2 is arranged on one side of the fixing sleeve 1, an expansion cavity 201 is formed between the flexible sheath 2 and the fixing sleeve 1, the flexible sheath 2 has a treatment cavity 202, the treatment cavity 202 is used to accommodate the patient's ankle joint, and the cavity wall of the treatment cavity 202 has a mounting hole 203, there are a plurality of mounting holes 203, which are evenly arranged on the cavity wall of the treatment cavity 202, the treatment cavity 202 is connected with the expansion cavity 201 through the mounting hole 203, a treatment probe 3 is arranged in the mounting hole 203, and an ultrasonic isolation sound-transmitting membrane 4 is arranged in the treatment cavity 202 and adhered to the inner wall of the flexible sheath 2 for blocking the mounting hole 203, an airway 5 extends from the fixing sleeve 1 to the expansion cavity 201, and is used to fill or discharge gas into the expansion cavity 201 and adjust the position of the treatment probe 3 and the patient's skin.

[0027] For example, Figure 1~Figure 3 As shown, the treatment probes 3 are arranged in the mounting holes 203 of the wall of the treatment cavity 202, and the number of them is large and evenly arranged, so that the ankle joint can be treated with ultrasound in all directions. Ultrasonic energy can act more evenly on various parts of the ankle joint, improving the accuracy and effectiveness of the treatment. For diseases such as ligament injury or arthritis of the ankle joint, evenly distributed treatment probes can be used for targeted treatment of different lesion areas, promoting local blood circulation and accelerating tissue repair.

[0028] The position of the treatment probe 3 and the patient's skin can be adjusted by filling or discharging gas into the expansion chamber 201 through the airway tube 5. In this way, the treatment probe 3 can be kept in close contact with the skin during operation according to the ankle size and treatment needs of different patients, ensuring that the ultrasonic energy can be effectively transmitted to the treatment site to achieve the best treatment effect. This avoids poor treatment effect or energy waste caused by a large distance between the treatment probe 3 and the skin.

[0029] The setting of the flexible sheath 2 provides a comfortable accommodation space for the patient's ankle joint. The flexible material can fit the shape of the ankle joint, reducing discomfort when wearing. At the same time, the ultrasonic isolation sound-permeable membrane 4 is adhered to the inner wall of the flexible sheath 2, which can not only ensure the penetration of ultrasonic energy, but also will not cause irritation to the skin, further improving the patient's comfort. After the treatment of a patient is completed, the doctor only needs to replace the ultrasonic isolation sound-permeable membrane 4, avoiding complicated disinfection steps and improving the treatment efficiency. At the same time, the ultrasonic isolation sound-permeable membrane 4 also ensures the airtightness of the expansion chamber 201 and reduces gas leakage, thereby ensuring that the flexible sheath 2 can evenly and tightly cover the patient's ankle joint, so that the position where the patient is covered by the flexible sheath 2 is evenly stressed, reducing the discomfort caused by the covering.

[0030] The design of the expansion chamber 201 and the adjustment function of the airway 5 enable the therapeutic device to adapt to the needs of different patients. Patients can adjust the pressure and position between the therapeutic probe 3 and the skin by adjusting the filling or discharge of gas according to their own feelings and treatment requirements to achieve a personalized treatment experience. This personalized adjustment method can improve the patient's acceptance and cooperation with the treatment.

[0031] The combined structure of the fixed sleeve 1 and the flexible sheath 2 provides a stable support for the therapeutic device, and can keep the position of the therapeutic device stable during the treatment process to avoid harm to the patient due to shaking or displacement. Compared with the handheld ultrasonic traction therapeutic device in the prior art, the design of the multiple therapeutic probes 3 of this scheme can simulate the movement trajectory of the human hand through the treatment probes 3 of different partitions through the scheme of starting and stopping in sequence, ensuring that the treatment effect is consistent with the doctor's handheld treatment effect, but the automated design improves the doctor's treatment efficiency. Compared with the handheld ultrasonic traction therapeutic device in the prior art, the flexible sheath 2 gives the patient a gentle and stable covering force, and the position of the treatment probe 3 will not cause a large deviation due to the doctor's mistakes, ensuring the stability of the treatment effect, while avoiding the hand fatigue caused by the doctor holding the treatment instrument for a long time. At the same time, because the treatment probe 3 does not need to be held by the doctor, the sound waves emitted by the treatment probe 3 can be controlled by the program to ensure the continuity of the sound wave treatment and improve the treatment effect.

[0032] The flexible sheath 2 is made of elastic material and can fit the physiological curves of the patient's ankle joint and sole tightly. In stretching therapy, this dynamic adaptability allows the sheath to deform with the movement of the sole, which not only maintains stable support for the treatment probe 3, but also does not hinder the doctor from guiding the sole of the foot to flex, extend, rotate, and so on. For example, when the doctor needs to pull the patient's sole to the dorsal side, the flexible sheath 2 can be stretched synchronously to avoid movement restriction or skin friction damage caused by the rigid structure. The ultrasonic isolation sound-transmitting membrane 4 is made of a flexible material (such as silicone), which can not only efficiently conduct ultrasonic energy, but also buffer the pressure between the treatment probe 3 and the skin during the stretching process. When the sole of the foot is guided to a specific angle, the sound-transmitting membrane can disperse the local pressure through elastic deformation, ensuring that the probe and the skin always maintain the best contact state, avoiding the attenuation of the treatment effect or patient discomfort caused by excessive squeezing.

[0033] The flexible sheath 2 and the fixed sheath 1 can achieve flexible fixation of the sole of the foot through the air pressure adjustment of the expansion chamber 201. On this basis, the doctor can apply stretching force to the sole of the foot through the rotating part 1001 and the fixing belt 1002 of the auxiliary frame 10. The sound-permeable membrane and sheath made of flexible material allow the sole of the foot to move freely within a small range, while the treatment probe 3 always keeps in contact with the skin through air pressure adjustment. This "flexible fixation + dynamic guidance" design allows stretching therapy and ultrasound therapy to be carried out simultaneously. For example, when the ankle joint is slowly stretched, the ultrasound probe continues to act on the target muscle group to enhance the treatment effect.

[0034] The material selection of the flexible sheath 2 and the sound-transmitting membrane 4 (such as medical-grade silicone or elastic fiber) has good biocompatibility and softness. During stretching therapy, the movement of the patient's sole will not be restricted by rigid components, and the flexible material can reduce the friction between the skin and the instrument, significantly reducing the pressure and fatigue during long-term treatment. When the patient needs to maintain the dorsiflexion position of the sole for ultrasonic treatment, the elastic support of the flexible sheath 2 can simulate natural muscle tension and avoid poor blood circulation caused by traditional hard fixation devices. Combined with the air pressure control of the expansion chamber 201, the flexible sheath 2 can dynamically adjust the wrapping force on the sole of the foot. The doctor can adjust the air pressure through the airway 5 according to the patient's condition and tolerance, so that the sheath can provide sufficient stability to cooperate with the stretching operation, and retain a certain amount of activity space to adapt to the individual differences of the patient. This personalized adjustment capability significantly improves the patient's acceptance of treatment, especially for children or people with sensitive joints.

[0035] The flexibility of the sound-transmitting membrane 4 enables it to maintain a close fit with the skin during the stretching process. Even if the sole of the foot is guided to an unconventional angle, the elastic stretching of the sound-transmitting membrane will not destroy its sealing and sound-transmitting properties, thereby ensuring the stable transmission of ultrasonic energy. This design breaks through the angle limitation of traditional rigid sound-transmitting windows, greatly improving the range of motion and flexibility of stretching therapy.

[0036] In some examples, the flexible sheath 2 has a traction portion 204, which is located in the expansion cavity 201. There are several traction portions 204, which are evenly arranged around the mounting hole 203. The new ankle joint ultrasonic traction therapy device also includes traction wires 6. There are several traction wires 6. The traction wires 6 form a traction wire group. A group of traction wire groups includes at least two traction wires 6. The traction portions 204 around the mounting hole 203 constitute a traction group. A traction group includes at least two traction portions 204. The traction wires 6 of a group of traction wires are respectively and one by one arranged on the traction portions 204 of a group of traction groups.

[0037] For example, Figure 3 As shown, the traction parts 204 are evenly arranged around the mounting hole 203 and connected thereto by the traction wire 6, so that the operator can more accurately adjust the position of the treatment probe 3. During the treatment process, the position and degree of ankle lesions of different patients may be different. The traction wire 6 can be used to adjust the angle and position of each treatment probe 3 individually or in combination, so that it can be more accurately aligned with the lesion site, thereby improving the pertinence of the ultrasonic treatment. For example, for local sprains or inflammations of the ankle joint, the treatment probe at the corresponding position can be more accurately placed close to the lesion area to enhance the treatment effect.

[0038] The arrangement of multiple traction parts 204 and traction wires 6 provides a multi-dimensional stretching function for the treatment probe 3. While performing ultrasonic treatment, the traction wires 6 can apply appropriate stretching force to the treatment probe 3 to make it fit the patient's treated part better, better simulate the movement trajectory of the doctor holding the treatment probe 3, and promote the recovery of the tissue around the joint.

[0039] By properly adjusting the traction wire 3 and the traction part 204, the ankle joint shape of the patient can be better fitted, reducing the discomfort caused by uneven contact between the device and the skin during treatment. At the same time, the multi-dimensional stretching function can also relieve the patient's joint pain and stiffness to a certain extent, making the patient more relaxed during treatment, which is conducive to improving the treatment effect.

[0040] The operation of the traction wire 6 is relatively simple, and the operator can control the treatment probe 3 and the stretching force by manually adjusting the traction wire 6. This simple operation method does not require complex techniques and equipment, reduces the operator's work difficulty, and improves the efficiency of treatment.

[0041] When performing ankle dorsiflexion stretching, the traction wire group can synchronously adjust the angle of the front probe so that it is always perpendicular to the stretched Achilles tendon. This dynamic angle matching ensures that the ultrasonic energy continues to act while the tissue is stretched, enhancing the therapeutic effect on Achilles tendon contracture. The therapeutic device can simulate the manipulation of a physical therapist. For example, when performing an "8"-shaped circular stretching, the therapeutic probe 3 synchronously adjusts the angle as the tension of the traction wire changes, so that the ultrasonic energy covers the joint movement trajectory, significantly improving the continuity of the treatment.

[0042] In some examples, the fixing sleeve 1 has an adjustment hole 101 , and the novel ankle joint ultrasonic traction therapy device further includes an adjustment member 7 , which is rotatably sealed on the adjustment hole 101 , and one end of the traction wire 6 is disposed on the adjustment member 7 , and the other end is disposed on the traction portion 204 .

[0043] For example, Figure 3 As shown, the adjusting member 7 is rotatably sealed and arranged on the adjusting hole 101 of the fixing sleeve 1, and the operator can easily adjust the tightness of the traction wire 6 by rotating the adjusting member 7. This operation mode is simple and intuitive, does not require complicated tools or techniques, and greatly improves the convenience of adjustment. During the treatment process, according to the treatment needs, the operator can quickly rotate the adjusting member 7, adjust the pulling force of the traction wire 6 on the traction part 204 in real time, and then change the position of the treatment probe 3. At the same time, the rotation of the adjusting member 7 can be realized by a micro motor, and the start and stop of the motor can be controlled by a program, which ensures the adaptability and quick response of the adjusting member 7 when different patients use the same device, thereby improving the treatment efficiency.

[0044] Since the adjusting member 7 is rotatable, the traction wire 6 can be precisely adjusted at multiple angles. The ankle joint conditions of different patients are different. The adjusting member 7 can be used to adjust the tension of the traction wire 9 in multiple directions, so that the treatment probe 3 can be more accurately aligned with the lesion site to meet personalized treatment needs. The cooperation between the adjusting member 7 and the traction wire 6 makes the positioning of the treatment probe 3 more accurate. By adjusting the tightness of the traction wire 6, the distance and angle between the treatment probe 3 and the patient's ankle skin can be fine-tuned to ensure that the ultrasonic energy can accurately act on the diseased tissue. This is crucial to improving the treatment effect, especially for some subtle lesions or areas that require precise treatment, and can more effectively promote tissue repair and recovery.

[0045] In some examples, the fixing sleeve 1 has a limiting portion 102, and there are multiple limiting portions 102. The limiting portions 102 are evenly arranged around the adjusting hole 101. The limiting portions 102 are used to limit the movement of the traction wire 6. The adjusting member 7 has a wire winding portion 701, and the wire winding portion 701 has a wire winding groove 702, and the wire winding groove 702 is used to accommodate the traction wire 6.

[0046] For example, Figure 3As shown, the limiting parts 102 on the fixing sleeve 1 are evenly arranged around the adjustment hole 101, which can effectively limit the movement of the traction wire 6. During the treatment process, due to the patient's activities or the operation of adjusting the traction wire 6, the traction wire 6 may be entangled or move around, and the limiting parts 102 can regulate the path of the traction wire 6 to keep it in an orderly state. This avoids mutual interference between the traction wires 6, ensures that each traction wire 6 can function independently and stably, thereby maintaining the normal operation of the treatment probe 3 and the traction device, and improving the overall stability of the device.

[0047] The wire winding portion 701 of the adjusting member 7 and its wire winding groove 702 provide a regular winding space for the traction wire 6. The traction wire 6 is wound in the wire winding groove 702, which increases the contact area and friction with the adjusting member 7, making the adjusting member 7 more stable and reliable when rotating to adjust the tightness of the traction wire 6, and is not prone to slipping or loosening. This reliable connection method ensures the accuracy and consistency of the adjustment operation and further improves the stability of the device.

[0048] In some examples, the treatment cavity 202 has a leg entrance and exit 205 and a foot entrance and exit 206, which are respectively located on both sides of the treatment cavity 202. The new ankle joint ultrasonic stretching therapy device also includes a fixed frame 8, a fixed sleeve 1 is arranged on the fixed frame 8, an adjustment frame 9 is rotatably arranged on the fixed frame 8 and is located on one side of the fixed sleeve 1, an auxiliary frame 10 is rotatably arranged on the adjustment frame 9 and is located on one side of the foot entrance and exit 206, which is used to abut against the patient's foot, and the adjustment frame 9 is perpendicular to the rotation axis of the auxiliary frame 10.

[0049] For example, Figure 1 As shown, the leg entrance and exit 205 and the sole entrance and exit 206 of the treatment cavity 202 are respectively located on both sides, providing clear access channels for the patient's legs and soles. The patient can easily put the ankle joint into the treatment cavity 202, and can also conveniently take it out after the treatment. The setting of the fixed frame 8, the adjustment frame 9 and the auxiliary frame 10 provides stable and adjustable support for the patient's limbs. The fixed sleeve 1 is arranged on the fixed frame 8 to ensure the overall stability of the therapeutic device. The adjustment frame 9 is rotatably arranged on the fixed frame 8, and the auxiliary frame 10 is rotatably arranged on the adjustment frame 9, and the rotation axes of the two are perpendicular, so that the auxiliary frame 10 can be adjusted in multiple directions. The patient can flexibly adjust the position and angle of the auxiliary frame 10 according to his or her body shape, ankle joint position and treatment needs, so that it can comfortably abut against the sole of the foot, provide better support and fixation for the ankle joint, and further improve the convenience of use.

[0050] The adjustability of the adjustment frame 9 and the auxiliary frame 10 enables the therapeutic device to adapt to the ankle joint position and posture of different patients. The size, shape and lesion site of the ankle joint of different patients are different. By adjusting the position and angle of the auxiliary frame 10, the therapeutic probe 3 can be better aligned with the lesion site of the patient, ensuring that the ultrasonic energy can accurately act on the affected area and improving the accuracy of the treatment. The auxiliary frame 10 abuts against the sole of the foot, which can effectively fix the sole of the patient and reduce the movement of the sole during the treatment process. The stable sole position helps to maintain the stability of the ankle joint, so that the therapeutic probe 3 can continuously and accurately act on the treatment site, avoiding deviation of the treatment position due to the movement of the patient's limbs, thereby ensuring the accuracy and effect of the treatment.

[0051] The rotating design of the adjustment frame 9 and the auxiliary frame 10 enables the therapeutic device to be adjusted at multiple angles. The adjustment frame 9 can be rotated on the fixed frame 8 to change the horizontal position of the auxiliary frame 10; the auxiliary frame 10 can be rotated on the adjustment frame 9 to adjust its vertical angle. This multi-angle adjustment function enables the therapeutic device to adapt to different treatment scenarios and patient needs, increasing the flexibility and versatility of the device. When performing different types of ankle joint treatments, such as rehabilitation training or ultrasound therapy, the position and angle of the auxiliary frame 10 can be adjusted according to specific requirements to achieve the best treatment effect.

[0052] The linkage movement of the auxiliary frame 10 and the adjustment frame 9 can simulate a variety of clinical stretching techniques. For example, when performing ankle dorsiflexion stretching, the auxiliary frame 10 can rotate upward along the horizontal axis of the adjustment frame 9, while the treatment probe 3 maintains the optimal contact angle with the skin through the tension adjustment of the traction wire 6. This dynamic coordination ensures the continuous and effective transmission of ultrasonic energy during the stretching process. The vertical rotation axis design of the adjustment frame 9 and the auxiliary frame 10 allows the therapeutic device to perform complex compound movements (such as rotation + flexion and extension).

[0053] In some examples, the novel ankle joint ultrasonic stretching therapy device also includes a fixing ring 11, there are two fixing rings 11, the two fixing rings 11 are respectively threadedly arranged at the leg entrance and exit 205 and the sole entrance and exit 206, and the fixing ring 11 has a pressing portion 1101, and the pressing portion 1101 is used to press the flexible sheath 2 onto the fixing frame 8.

[0054] For example, Figure 2As shown, two fixing rings 11 are respectively threadedly arranged at the leg entrance 205 and the sole entrance 206, and the flexible sheath 2 can be firmly pressed on the fixing frame 8 by means of threaded connection. During the treatment process, the patient's limb movement may produce a certain tension or pressure on the flexible sheath 2, and the pressing portion 1101 of the fixing ring can effectively prevent the flexible sheath 2 from being displaced or loosened, ensuring the stability of the position of components such as the treatment probe 3, thereby ensuring the normal progress of ultrasonic treatment and stretching treatment. The fixing ring 11 tightly connects the flexible sheath 2 with the fixing frame 1, enhancing the structural stability of the entire therapeutic device. It makes the flexible sheath 2, the fixing frame 8 and other related components form a stable whole, reducing the risk of equipment failure caused by loose components. During long-term use, the stable structure helps to maintain the performance of the therapeutic device and extend the service life of the device.

[0055] The fixing ring 11 is arranged at the leg entrance 205 and the foot entrance 206 and the flexible sheath 2 is compressed, which can effectively improve the sealing of the expansion chamber 201. The gas pressure in the expansion chamber 201 is crucial for adjusting the position of the treatment probe 3 and the patient's skin. Good sealing can prevent gas leakage and ensure the stability of the gas pressure, thereby ensuring that the treatment probe 3 can be accurately adjusted to a suitable position to achieve the best treatment effect. The sealing effect of the fixing ring 11 can also prevent external dust, impurities, etc. from entering the treatment chamber 202 and the expansion chamber 201. This not only protects the internal components such as the treatment probe 3 and prevents them from being contaminated and affecting performance, but also provides a cleaner and more hygienic treatment environment for patients, reducing the risk of infection.

[0056] In some examples, the auxiliary frame 10 includes a rotating part 1001, which is rotatably set on the adjustment frame 9, a fixed belt 1002 is hingedly set on the rotating part 1001, and the fixed belt 1002 has a fixed tooth portion 1003. A connecting member 1004 is set on the rotating part 1001, and the connecting member 1004 has a connecting channel 1005, and the connecting channel 1005 is used for the fixing belt 1002 to pass through. A fixing member 1006 is swingably set on the connecting member 1004, and the fixing member 1006 has a fixed end 1007. After the fixing member 1006 swings, the fixed end 1007 abuts against or cancels the abutment with the fixed tooth portion 1003.

[0057] For example, Figure 4As shown, the fixing belt 1002 is hinged on the rotating part 1001, and passes through the connecting member 1004 through the connecting channel 1005, and cooperates with the fixed end 1007 of the fixing member 1006 to abut against the fixed tooth portion 1003, so as to achieve a firm fixation of the patient's sole. During the treatment process, the patient's sole may be displaced due to unconscious movements or movements required for treatment, and this fixing structure can effectively prevent the sole from moving, ensure that the ankle joint maintains a stable position during treatment, and enable the treatment probe 3 to continuously and accurately act on the treatment site, thereby improving the treatment effect. The setting of the fixing belt 1002 and the cooperation between the fixed tooth portion 1003 and the fixed end 1007 can adapt to the sole sizes of different patients. By adjusting the passing length of the fixing belt 1002 in the connecting channel 1005 and fixing the fixing belt 1002 in a suitable position using the fixing member 1006, the auxiliary frame 10 can be closely fitted to the soles of different patients, providing a better fixing effect.

[0058] The rotating part 1001 is rotatably arranged on the adjusting frame 9, so that the auxiliary frame 10 can be adjusted at multiple angles. Combined with the rotating function of the adjusting frame 9 itself, the adjustment range of the auxiliary frame 10 can be further expanded. During the treatment process, according to the specific conditions of the patient's ankle joint and the treatment needs, the angle of the auxiliary frame 10 can be flexibly adjusted so that the fixing belt 1002 can fix the sole of the foot at the best angle and position, providing more suitable support and fixation for the ankle joint. The fixing belt 1002 is hinged on the rotating part 1001, and can be adjusted to a certain extent according to the shape and position of the sole when fixing the sole, thereby increasing the flexibility of fixation. At the same time, the swinging design of the fixing member 1006 makes the fixing and loosening operations of the fixing belt 1002 more convenient, and the tightness of the fixing belt 1002 can be adjusted at any time according to the needs during the treatment process to adapt to the patient's comfort and treatment requirements.

[0059] In some examples, the auxiliary frame 10 further includes an elastic member 1008 , one end of the elastic member 1008 acts on the connecting member 1004 , and the other end of the elastic member 1008 acts on the fixing member 1006 , so as to provide a force for the fixing end 1007 to abut against the fixing tooth portion 1003 .

[0060] For example, Figure 4 As shown, one end of the elastic member 1008 acts on the connecting member 1004, and the other end acts on the fixing member 1006, which can provide a continuous and stable force for the abutment between the fixing end 1007 and the fixing tooth portion 1003. During the treatment process, even if the patient's sole moves or changes slightly, the elastic force of the elastic member 1008 can ensure that the fixing belt 1002 is always in a suitable tightening state to prevent the sole from loosening or shifting.

[0061] In some examples, the novel ankle joint ultrasonic stretching therapy device also includes a first rotating driving member 12, which is disposed on the fixed frame 8 and is used to drive the adjusting frame 9 to rotate, and a second rotating driving member 13 is disposed on the adjusting frame 9 and is used to drive the rotating part 1001 to rotate.

[0062] For example, Figure 1 As shown, the first rotating driving member 12 is arranged on the fixing frame 8 to drive the adjusting frame 9 to rotate, and the second rotating driving member 13 is arranged on the adjusting frame 9 to drive the rotating part 1001 to rotate, so that the auxiliary frame 10 can be accurately adjusted in multiple dimensions. During the treatment process, the location and degree of ankle lesions of different patients are different. Through these two driving members, the position and angle of the auxiliary frame 10 can be accurately adjusted, so that the treatment probe 3 can be more accurately aligned with the lesion site, ensuring that the ultrasonic energy can accurately act on the affected area, and improving the pertinence and effectiveness of the treatment.

[0063] In some examples, the airway tube 5 has an air port 501, and there are multiple airway tubes 5, and the air ports 501 of the multiple airway tubes 5 are evenly arranged in the expansion cavity 201. The flexible sheath 2 has a connecting ring 207, and the connecting ring 207 is used to fix the airway tube 5. The new ankle joint ultrasonic stretching therapy device also includes an air pump 14, which is arranged on the fixing frame 8, and the airway tube 5 is connected to the air pump 14.

[0064] For example, Figure 3 As shown, the air ports 501 of several air guide tubes 5 are evenly arranged in the expansion cavity 201, so that the gas delivered by the air pump 14 can be more evenly distributed in the expansion cavity 201. This ensures that the gas pressure in each part of the expansion cavity 201 is relatively consistent, so that the treatment probe 3 can be evenly close to the patient's skin, avoiding the situation where some probes have poor contact or excessive pressure due to uneven local pressure. Multiple air guide tubes cooperate with the air pump 14 to achieve more precise pressure control. The operator can adjust the flow and pressure of the gas through the air pump 14 according to the needs and treatment stages of different patients, and then adjust the distance and pressure between the treatment probe 3 and the skin. This precise adjustment capability is particularly important for some patients who are sensitive to treatment pressure, and can provide a personalized treatment experience and enhance the effectiveness of treatment.

[0065] The connecting ring 207 on the flexible sheath 2 is used to fix the airway tube 5, effectively preventing the airway tube 5 from loosening or shifting during use, and avoiding the airway tube 5 from falling off or shifting and affecting the gas pressure control of the expansion chamber 201 and the position adjustment of the treatment probe 3, thereby improving the stability and reliability of the equipment operation.
