Description

Integrated treatment device using shock waves and ultrasound The present invention relates to an integrated stimulation device utilizing shock waves (ESWT) and high-intensity ultrasound (HIFU) as a non-invasive stimulation device used in medical and cosmetic fields, such as for the treatment of musculoskeletal diseases, pain relief, tissue regeneration, improvement of skin elasticity, and fat coagulation. Extracorporeal Shock Wave Therapy (ESWT) and High-Intensity Focused Ultrasound (HIFU) are used in various medical and cosmetic fields as non-invasive treatment methods. Extracorporeal Shockwave Therapy (ESWT) is effective for non-invasively relieving pain and promoting tissue regeneration. It is primarily used for musculoskeletal conditions such as muscle pain, tendinitis, and plantar fasciitis, and has the advantage of increasing blood flow to reduce inflammation and accelerate recovery. Furthermore, its quick treatment time and simple procedure allow patients to return to their daily lives immediately, making it convenient. As such, ESWT has established itself as a powerful therapeutic tool for pain management and tissue healing. However, ESWT has limitations in improving surface tissues and is ineffective for cosmetic treatments such as improving skin elasticity or cell coagulation. Furthermore, strong shockwaves can cause temporary pain or side effects in some patients, and often lack immediate effects, with results appearing over time. Therefore, other forms of energy are currently required for precise treatment aimed at improving surface tissues. High-Intensity Focused Ultrasound (HIFU) devices utilize high-intensity ultrasound to concentrate heat on specific tissues, serving in cosmetic applications such as skin lifting, wrinkle reduction, and fat coagulation, as well as in tumor treatment. They provide long-term skin improvement by non-invasively stimulating collagen production, and some procedures offer immediate lifting effects. Furthermore, high-intensity ultrasound enables precise focusing, allowing for the minimization of damage to surrounding tissues during tumor removal. However, since HIFU primarily uses thermal energy, its effectiveness in treating musculoskeletal pain or inflammation is limited. Additionally, the high cost of equipment and procedures is a limitation, and precise operation by skilled medical professionals is required. While ESWT and HIFU each have strengths in musculoskeletal treatment and skin elasticity improvement, respectively, there are clear limitations to using them as individual devices. Shockwaves stimulate deep tissues but are insufficient for improving surface tissues, and ultrasound is effective for the skin and subcutaneous tissues but has limitations in relieving pain caused by physical impact. Therefore, using the two devices separately is pointed out as a limitation due to issues such as increased treatment time, higher equipment investment costs, and increased work fatigue for medical staff.
