Description

Technical Field

[0001] This invention relates to the field of aerospace medical equipment, specifically to a portable adaptive extracorporeal shock wave orthopedic treatment device suitable for microgravity environments such as space stations. Background Technology

[0002] Extracorporeal Shock Wave Therapy (ESWT) is a non-invasive physical therapy that uses high-energy sound waves to act on the affected area, promoting tissue repair, relieving pain, and improving blood circulation. This technology has been widely used in terrestrial medicine for orthopedic conditions such as plantar fasciitis, frozen shoulder, and delayed fracture healing.

[0003] Extracorporeal shock wave therapy (ESWB) devices utilize the properties of piezoelectric ceramic crystals. When a high-voltage pulse passes through, the volume of the piezoelectric ceramic crystal expands or contracts, generating superimposed pressure and tension waves, which in turn produce shock waves. These shock waves can be used to treat human bones, muscles, tendons, and other tissues, promoting tissue repair and relieving pain.

[0004] During long-term space missions, astronauts experience a 1-2% monthly loss of bone density due to weightlessness (especially in weight-bearing bones such as the calcaneus and lumbar vertebrae), requiring more frequent (1-2 times per week) shockwave interventions. Furthermore, the accompanying muscle atrophy and tendon degeneration necessitate significant differences between space and terrestrial treatments. The space environment demands lower energy and higher frequency pulses for the shockwave parameters. Studies have found that extracorporeal shock wave therapy (ESWT) can promote nutrient transport in the lacunae and canaliculi of bone microstructures, allowing deeper bone cells to receive nutrients and promoting bone cell activity, thus achieving a healthy physiological state of bone. ESWT has been proven to effectively stimulate bone formation, promote bone healing, and relieve bone pain. Its principle involves focusing high-energy sound waves onto target tissues to generate mechanical stress, activating osteoblasts, and further validating the therapeutic effects of extracorporeal shock wave therapy on bone.

[0005] Although ESWT is relatively mature in terrestrial medical applications, its existing technical architecture has the following inherent defects, making it difficult to apply directly to aerospace environments:

[0006] 1. Relying on a liquid coupling medium, the treatment head needs to be coated with gel or water bag for contact with the skin, otherwise the energy loss will be severe (attenuation can reach 70%), and the medium is easy to disperse under microgravity, which will pollute the environment inside the chamber;

[0007] 2. It is gravity-dependent. Traditional mechanical positioning systems rely on gravity for stability, which can easily lead to treatment head displacement exceeding ±5mm in a weightless state.

[0008] 3. Insufficient radiation resistance: Traditional equipment has not been hardened to resist radiation (such as SEU protection), and the control system may fail due to cosmic rays during long-term missions.

[0009] The existing equipment also has some problems and is not suitable for the aerospace environment:

[0010] 1. Exceeding size and weight limits: For example, electrohydraulic devices require high-voltage power supplies and water circulation systems, while electromagnetic devices rely on heavy coil structures, making it difficult to meet the strict mass limits of spacecraft (usually requiring a single device to be ≤15kg); the space available for medical equipment inside the International Space Station (ISS) is usually ≤0.5m³, while traditional ESWT devices are generally ≥0.8m³ in size, and are usually desktop devices, requiring astronauts to go to the hospital for treatment, which is inconvenient to use and the devices are not easy to operate.

[0011] 2. Functional consumption does not meet the standard: The instantaneous power consumption of the electrohydraulic ESWT can reach 2kW, far exceeding the NASA ISS fluid control standard requirement that the peak power of a single device should be ≤500W;

[0012] 3. Other limitations: Hydraulic and electromagnetic devices have problems such as low energy, poor treatment effect, limited treatment coverage area, and the need for frequent replacement of internal components; pneumatic devices have disadvantages such as high noise, short life and unstable waveform. Summary of the Invention

[0013] The purpose of this invention is to provide a portable adaptive extracorporeal shock wave orthopedic treatment device designed specifically for the space environment, so as to achieve more portable, more efficient and more stable treatment results, in order to prevent and combat bone loss in astronauts.

[0014] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0015] A portable adaptive extracorporeal shockwave orthopedic treatment device, characterized in that it comprises a strap, a treatment head, and a fixation strap, wherein:

[0016] The strap consists of a strap body and a base. The cross-sectional shape of the strap body is U-shaped. The edge of the base is connected to the edge of the strap body, forming a closed cavity with the strap body.

[0017] Multiple mounting holes are formed at intervals on the substrate for mounting the treatment head; the treatment head is mounted at the mounting holes on the substrate, and the functional end of the treatment head extends away from the cavity.

[0018] Treatment heads in different locations can generate extracorporeal shock waves of varying intensities and frequencies to act on different parts of the body, depending on the degree of bone density loss.

[0019] The fixing straps are installed at both ends of the bandage. When in use, the bandage is wrapped around the part of the body that needs to be treated and fixed by the fixing straps. The fixing straps have a certain length and can be adjusted according to different treatment areas.

[0020] The multiple mounting holes are arranged in an array.

[0021] The treatment head includes an insulating cover, a housing, and, from bottom to top, an elastic coupling surface, an acoustic transducer, an acoustic lens, a piezoelectric ceramic array, electrode plates, and a pulsed high-voltage generator, wherein:

[0022] The insulating cover is an insulator, shaped like a cylindrical body with a lid but no bottom, used to protect the circuit safety; the shell is cylindrical, providing mechanical support for the entire treatment head; the elastic coupling surface conforms to the curve of the body part; the acoustic transducer generates different feedback signals based on the identified bone density loss and soft tissue thickness; the pulsed high-voltage generator generates high-voltage electrical pulses that meet the treatment requirements based on the received feedback signals; the high-voltage electrical pulses act on the piezoelectric ceramic array through the electrode plates; the piezoelectric ceramic array generates high-energy shock waves of corresponding intensity under the action of the high-voltage electrical pulses to treat the human bone tissue; the acoustic lens focuses the shock waves generated by the piezoelectric ceramic array in different directions onto the target area, achieving ideal distribution and intensity within the target area.

[0023] An external main power supply powers the pulsed high-voltage generator in each treatment head, making the pulsed high-voltage generator the power source for each treatment head.

[0024] The current circuit in the treatment head is as follows: positive electrode of pulsed high voltage generator — electrode plate — piezoelectric ceramic array — acoustic transducer — negative electrode of pulsed high voltage generator.

[0025] The elastic coupling surface is attached and fixed to the acoustic transducer; the insulating cover wraps the pulsed high voltage generator and the electrode plate, and the axis of the cylinder coincides with the axis of the electrode plate and the piezoelectric ceramic array.

[0026] The housing is cylindrical, with its bottom sealed to the acoustic transducer; together with the insulating cover, it forms a closed space, creating an encapsulated structure; the acoustic lens is pressed against the housing by a fixing ring, which is detached and connected by a snap-fit; the acoustic lens is connected to the piezoelectric ceramic array using acoustic matching adhesive;

[0027] The positive electrode of the pulsed high voltage generator is connected to the electrode plate via a cable; the electrode plate is bonded to the piezoelectric ceramic array via conductive adhesive; the housing is provided with a wire groove, and the insulating cover is provided with a wire through hole; the piezoelectric ceramic array is connected to the acoustic transducer via a wire; the acoustic transducer is connected to the negative electrode of the pulsed high voltage generator via a wire.

[0028] The pulsed high-voltage generator is powered by an external low-voltage power supply. Its internal circuitry includes PWM pulse modulation, a switching transistor Q1, transformers T1 and T2, a multi-stage rectifier boost circuit, transformer T2, and a protection circuit. Feedback signals from the acoustic transducer trigger PWM pulse modulation to generate electrical pulses, controlling the switching transistor Q1. The circuit uses transformer T1 to convert low-voltage DC pulses into high-frequency AC pulses, which are then boosted step-by-step through a multi-stage rectifier circuit and further boosted by transformer T2 to output high-voltage pulses. The protection circuit includes voltage regulation and overcurrent protection functions to ensure stable output and circuit safety, ultimately generating high-voltage pulses of varying intensities based on different feedback signals.

[0029] The electrode sheet is a copper sheet or an aluminum sheet; the piezoelectric ceramic array is formed by arranging and combining several circular wafers.

[0030] The focal length of the acoustic lens ranges from 30mm to 150mm; the focal diameter ranges from 2mm to 8mm; and the radiation length ranges from 10mm to 50mm.

[0031] The elastic coupling surface, acoustic transducer, acoustic lens, piezoelectric ceramic array, electrode sheet, pulsed high voltage generator, insulating cover, and housing are all arranged coaxially.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The treatment device of the present invention can adaptively identify different locations and degrees of bone density loss in the astronaut's legs, and apply precise and controllable external shock waves to prevent and treat space bone loss (osteoporosis).

[0034] 2. The treatment device of the present invention can be applied to the parts of the human body that need treatment. It identifies the degree of bone density and soft tissue depth through a sound transducer and a sensor, and then controls the corresponding shock wave intensity through a feedback signal circuit. This allows the treatment head at the location with high bone loss to generate a higher intensity shock wave, focusing the energy on the treatment site for targeted treatment.

[0035] 3. The treatment device of the present invention is portable and small in size, and can be used in a microgravity environment. It is not limited to the treatment room of a medical institution. Patients can operate it themselves and receive treatment anytime and anywhere, which improves the convenience of treatment.

[0036] 4. The adaptiveness of the treatment device of the present invention is achieved by recognizing the degree of bone density loss and soft tissue anisotropy to control shock waves of different intensities and depths for treatment. The shock wave energy generated at this time is more precise and stable in a microgravity environment and the process is noiseless. It has the characteristics of simple structure, long service life and applicability to large-area treatment. Attached Figure Description

[0046] To make the objectives, methods of use, and effects of this invention clearer, the following description, in conjunction with the accompanying drawings and embodiments, further illustrates the solution of this invention. The illustrative embodiments and descriptions of this invention are only for explaining this invention and are not intended to limit this invention.

[0047] like Figures 1 to 3As shown, a portable adaptive extracorporeal shockwave orthopedic treatment device of the present invention includes a strap, a treatment head 3, and a fixation strap 1.

[0048] The strap consists of a strap body 2 and a base 4. The strap body 2 has a U-shaped cross-section and can be made of medical-grade silicone or other suitable materials. The edge of the base 4 connects to the edge of the strap body 2, forming a closed cavity. Multiple mounting holes are formed at intervals on the base 4 for mounting the treatment head 3. The mounting holes are arranged in an array. In one embodiment of the invention, the base 4 is made of biocompatible high-grade medical-grade silicone material.

[0049] The treatment head 3 is mounted in a mounting hole on the base 4, with the head (acting end) of the treatment head 3 extending away from the cavity. Figure 4 As shown, the treatment head 3 includes an insulating cover 10, a housing 9, and, from bottom to top (positioned in the figure), an elastic coupling surface 12, an acoustic transducer 11, an acoustic lens 8, a piezoelectric ceramic array 7, an electrode plate 6, and a pulsed high-voltage generator 5. The specific structure is as follows:

[0050] The elastic coupling surface 12 is made of highly elastic medical-grade silicone, which can conform well to the curves of the body, ensuring tight contact and reducing energy reflection and loss at the air interface. Furthermore, the elastic coupling surface 12 can withstand repeated mechanical stress from shock waves without easily aging or cracking. Silicone has high biocompatibility, is safe and harmless, and will not cause skin allergies or irritation. The elastic coupling surface 12 is attached and fixedly connected to the acoustic transducer 11.

[0051] The insulating cover 10 is an insulator, shaped as a cylindrical body with a lid but no bottom, used to protect the circuit safety. The insulating cover 10 wraps around the pulsed high-voltage generator 5 and the electrode plate 6, with the axis of the cylindrical body coinciding with the axis of the electrode plate 6 and the piezoelectric ceramic array 7 (centered).

[0052] The housing 9 is cylindrical, with its bottom sealed to the acoustic transducer 11. Together with the insulating cover 10, it forms a closed space, creating an encapsulation structure that provides mechanical support for the entire module. This encapsulation structure ensures the module's airtightness and stability, preventing external moisture, dust, and other contaminants from entering the module and affecting its performance and lifespan.

[0053] The acoustic lens 8 is pressed against the housing 9 by a retaining ring, which is detached and connected by a snap fastener. The focal length of the acoustic lens 8 ranges from 30mm to 150mm; the focal diameter ranges from 2mm to 8mm; and the radiation length ranges from 10mm to 50mm.

[0054] The elastic coupling surface 12, acoustic transducer 11, acoustic lens 8, piezoelectric ceramic array 7, electrode sheet 6, pulsed high voltage generator 5, insulating cover 10, and housing 9 are all arranged coaxially.

[0055] When the device is powered on, the external main power supply provides power to the pulsed high-voltage generator 5 of each treatment head 3, making the pulsed high-voltage generator 5 the power source for each treatment head 3. The current loop in the treatment head 3 is as follows: pulsed high-voltage generator 5 (positive terminal) — electrode plate 6 — piezoelectric ceramic array 7 — acoustic transducer 11 — pulsed high-voltage generator 5 (negative terminal). The positive terminal of the pulsed high-voltage generator 5 is connected to the electrode plate 6 via a cable; the electrode plate 6 is bonded to the piezoelectric ceramic array 7 with conductive adhesive; the housing 9 has a wire groove inside, and the insulating cover 10 has a wire through hole. The piezoelectric ceramic array 7 is connected to the acoustic transducer 11 via a wire, and the acoustic transducer 11 is connected to the negative terminal of the pulsed high-voltage generator 5 via a wire.

[0056] The acoustic transducer 11 is an existing device that emits high-frequency sound waves (typically 0.1-1.5MHz) through a sensor, which penetrate the bone. A receiver detects the sound wave signal after penetration, records the propagation time and intensity attenuation, and calculates the sound velocity, broadband attenuation, and backscatter signal after penetration using an algorithm. The faster the penetration speed, the higher the bone density and the healthier the bones. Combining the sound velocity and broadband attenuation after penetration, a quantitative index is generated to measure the degree of bone density and soft tissue thickness in different leg locations, thereby assessing the risk of osteoporosis, such as: normal bone density, mild loss, moderate loss, and severe loss. When bone density loss and soft tissue thickness are identified, different feedback signals (electrical signals) are generated.

[0057] The circuit structure of the pulsed high-voltage generator 5 is as follows: Figure 5 As shown, the circuit is powered by an external low-voltage power supply. The circuit includes PWM pulse modulation, a switching transistor Q1, transformers T1 and T2, a multi-stage rectifier boost circuit, transformer T2, and a protection circuit. The feedback signal generated by the acoustic transducer 11 triggers the PWM pulse modulation to generate electrical pulses, controlling the on / off state of Q1. The circuit uses transformer T1 to convert the low-voltage DC pulses into high-frequency AC pulses, which are then boosted step-by-step through a multi-stage rectifier circuit, and finally boosted again by transformer T2 to output high-voltage electrical pulses. The protection circuit includes voltage regulation control and overcurrent protection functions to ensure stable output and circuit safety, ultimately generating high-voltage electrical pulses of different intensities based on different feedback signals. When the pulsed high-voltage generator 5 receives feedback signals indicating the degree of bone loss at different locations, through the coordinated operation of the circuit, it can precisely control the frequency, amplitude, and pulse width of the generated high-voltage electrical pulses to produce high-voltage electrical pulses that meet the treatment requirements.

[0058] Frequency determines the emission frequency of the shock wave; different frequency settings are required for the treatment of different bone densities and soft tissue thicknesses. Amplitude affects the energy intensity of the shock wave, while pulse width affects the waveform and duration of the shock wave.

[0059] A high-voltage electric pulse is applied to the piezoelectric ceramic array 7 through the electrode sheet 6.

[0060] The piezoelectric ceramic array 7 is formed by arranging several circular crystals in a ring or spherical array. The high-voltage electric pulse acts on the piezoelectric ceramic array 7, causing it to generate a high-energy shock wave of corresponding intensity, which treats the bone tissue. Under the action of the high-voltage electric pulse, the piezoelectric ceramic array 7, acting as a shock wave generating element, undergoes mechanical deformation of its internal piezoelectric ceramic crystals. Because this deformation process is very rapid, it generates stress waves, i.e., pressure waves. When the piezoelectric ceramic crystals recover, tension waves are generated. When several piezoelectric ceramic crystals act simultaneously, a shock wave is generated.

[0061] The acoustic lens 8 focuses the shock waves generated by the piezoelectric ceramic array 7, which are oriented in different directions, onto the target area, achieving an ideal distribution and intensity of the shock waves within the target area. This enhances the intensity and focusing effect of the shock waves, allowing them to be effectively transmitted to human tissue and reducing energy loss. The acoustic lens 8 is connected to the piezoelectric ceramic array 7 using acoustic matching adhesive.

[0062] The treatment head 3 at different locations generates extracorporeal shock waves of varying intensities and frequencies based on the bone density loss indicated by the feedback signals, achieving a more efficient treatment effect.

[0063] The fixing strap 1 is installed at both ends of the bandage. In use, the bandage is wrapped around the area of ​​the body requiring treatment, such as the leg or waist, and secured by the fixing strap 1. The fixing strap 1 has a certain length and can be adjusted according to different treatment areas.

[0064] Example

[0065] In this embodiment, the housing 9 of the treatment head 3 in the treatment device is made of carbon fiber composite material, with an overall weight of approximately 300g and a thickness of 5mm. The treatment head 3 has a diameter of approximately 22mm, and the fixing strap 1 is approximately 95mm long and 15mm wide. The acoustic lens 8 has a focal length of 30mm, a focal diameter of 2mm, and a radiation length of 10mm. There are 6 treatment heads 3 distributed axially and 15 circumferentially in the treatment device, for a total of 90 generating devices. The electrode plates 6 are all made of copper.

[0066] like Figure 6 As shown, each piezoelectric ceramic array 7 in this embodiment includes 15 uniformly arranged piezoelectric ceramic wafers, and the device contains a total of 1350 piezoelectric ceramic wafers.

[0067] Place the treatment device around the area on the recipient's body where treatment is needed, and adjust the multiple securing straps 1 to fix the device in place. Turn on the power and begin use.

[0068] The treatment device uses an acoustic transducer 11 to assess the bone density loss and soft tissue thickness at the treatment site and generates a feedback signal. Based on the feedback signal, it precisely controls a pulsed high-voltage generator 5 to adjust parameters such as the frequency, amplitude, and pulse width of the electrical pulses. In this embodiment, the acoustic transducer 11 is a High Intensity Focused Ultrasound manufactured by Siansonic.

[0069] The pulsed high voltage generator 5 transmits high-frequency voltage pulse signals to several piezoelectric ceramic arrays 7 between the electrode plate 6 and the acoustic lens 8, causing the piezoelectric ceramic arrays 7 to generate shock waves; the acoustic lens 8 focuses the divergent shock wave energy generated by the piezoelectric ceramic arrays 7 to precisely treat the corresponding location.

[0070] In this embodiment, when mild bone density loss is detected, a concentration of 0.3-0.5 mJ / mm² will be generated. 2 The shock wave energy is focused to a depth of 15-20 mm; moderate leakage produces 0.5-0.8 mJ / mm². 2 The energy is focused at a depth of 25-30mm; severe loss will produce 0.8-1.2mJ / mm. 2 The energy is focused to a depth of 35-40mm. Shock waves can carry a certain amount of energy, and when the mechanical stress they generate is transmitted to human tissue, they can promote the delivery of nutrients and blood circulation to the microscopic bone structure, lacunae-canaliculi system, and stimulate cell repair and regeneration, among other therapeutic effects.

[0071] Comparison images before and after extracorporeal shock wave therapy of the lacuna-canaliculus using the extracorporeal shock wave orthopedic treatment device of this embodiment are shown below. Figure 7 As shown, the left image represents bone cells not treated with shockwave therapy, while the right image represents bone cells treated with shockwave therapy at an intensity of 8 bar. Stronger fluorescence indicates higher material transport efficiency in bone cells, resulting in more nutrients and better bone health. The images demonstrate that the extracorporeal shockwave orthopedic treatment device of this embodiment can enhance the material exchange efficiency in bone cells, promote osteoblast growth, and achieve the goal of preventing and treating bone loss in space.

[0072] Figure 8The graph shows the change in mass transfer efficiency during extracorporeal shock wave therapy with increasing shock wave intensity. The change in fluorescence intensity in the lacunae represents the change in mass transfer efficiency. By observing the trend of the average fluorescence intensity, it can be concluded that shock waves of different intensities acting on the lacunae-canaliculi all promote the mass transfer efficiency within osteocytes, and the promoting effect becomes stronger with increasing shock wave intensity, enabling osteocytes to reach a healthy state for the treatment of bone loss.

[0073] During the use of the treatment device, the acoustic transducer continuously tests and provides feedback on the current bone density information, enabling adaptive adjustment of the frequency and energy intensity of the treatment shockwave, thus allowing for more efficient and convenient treatment.
