Description

Shock wave generator with a plurality of shock wave generating units {SHOCK WAVE GENERATOR WITH A PLURALITY OF SHOCK WAVE GENERATORS} The present disclosure relates to medical devices, specifically to extracorporeal shockwave generators. This project (result) is the result of the Local Government-University Cooperation-based Regional Innovation Project conducted in 2023 with funding from the Ministry of Education and support from the National Research Foundation of Korea. (2021RIS-001) Extracorporeal Shock-Wave Therapy (ESWT) is a state-of-the-art medical device that uses shock waves to treat conditions such as pain and urinary stones, offering rapid therapeutic effects with a short procedure time. Specifically, the shockwave therapy device may include a shockwave generating unit that converts an electrical signal into a shockwave, such as ultrasound, using the piezo effect. Shock waves can have characteristics almost identical to ultrasound. Ultrasonic energy generated from a single point can be focused to a single point using a reflector, or by arranging ultrasound generators such as PIEZO in a spherical shape to focus to a single point, or by fabricating ultrasound generators such as PIEZO in a spherical shape to focus to a single point. As the shock waves generated in this way are concentrated on the area requiring treatment, mechanical stimulation is applied within the body, thereby stimulating the release of factors related to angiogenesis, promoting the proliferation of new blood vessels for the healing of tendons and bones, improving blood supply, and increasing blood flow. This promotes the remodeling of blood vessels or the formation of new blood vessels, which is effective for pain relief. Shockwave generators must output different amounts of energy depending on the individual's physical condition, the purpose of treatment, the body part, and the type of treatment. In one embodiment, the shockwave generator can be used for a patient's shoulder joint pain, tennis elbow, plantar fasciitis, chronic tendon pain, muscle pain, etc., and the patient can receive treatment without hospitalization, anesthesia, or surgery, allowing them to return to daily life immediately after treatment. The treatment process of the shockwave generator is carried out by applying a gel or similar substance to the treatment area and then bringing it into contact with the area. The shock wave generator can determine the magnitude of energy by adjusting conditions such as the conversion efficiency, driving voltage, and cross-sectional area of the piezoelectric element included in the shock wave generator. However, shock wave generators may have limitations in increasing the magnitude of energy depending on the characteristics of the piezoelectric element.
