Precision Targeted Drug Therapy–Ultrasonic Conductive Positioning Drug Delivery Technology Ultrasonic Conductive Targeted Drug Delivery Technology is the latest achievement in the field of modern precision therapy technology. It is the application of modern physics, so that the drug through the skin barrier, directional, positioning, speed, quantitative entry into the diseased tissues and organs, and then into the blood circulation, to achieve the purpose of targeted drug delivery, non-invasive intervention, known as the third generation of drug delivery methods after oral and injectable international pharmaceutical industry. The U.S. FDA has designated this technology as one of the six new medical technologies to be developed in the next decade, and has successfully used this technology for more than 300 kinds of drugs in nine categories, such as anti-inflammatory drugs, analgesics, local anesthetics and muscle relaxants, especially some highly active biological drugs such as bone growth factor and vascular endothelial growth factor, which can rebuild local circulation and promote the growth of bone scabs, and play a unique therapeutic effect in the treatment of osteonecrosis, bone discontinuity and osteomyelitis. It has played a unique therapeutic effect in the treatment of osteonecrosis, osteonecrosis and osteomyelitis. With this technology, a variety of latest special agents can be launched to the deep part of the lesion, and the efficacy time of a single treatment can be extended to 7-10 days, and complete remission can be achieved; at the same time, anti-inflammatory, anti-swelling and tissue repair treatment can also be carried out. (1) Bone growth factor and vascular endothelial growth factor can be introduced to promote fracture healing and treat osteonecrosis and osteonecrosis. (2) Introduction of antimicrobial agents to treat osteomyelitis after debridement surgery, as well as soft tissue infections, chronic inflammation of the abdominal cavity, lung infections, chronic prostatitis, etc. (3) Analgesics, local anesthetics, muscle relaxants and Chinese herbal medicine introduction for the treatment of neck, shoulder, back and leg pain, trauma and post-surgical pain relief.
