Interventional ultrasound is a minimally invasive diagnostic and therapeutic measure performed under the guidance of ultrasound in a B-ultrasound machine. Interventional ultrasound is an interdisciplinary field between ultrasound and surgery. As a branch of modern ultrasound medicine, it is a new technology developed on the basis of ultrasound imaging to further meet the needs of clinical diagnosis and treatment.
Interventional ultrasound mainly includes ultrasound-guided puncture biopsy, catheterization and drainage under ultrasound guidance, puncture and drainage, fluid drainage, and ultrasound-guided ablation therapy. With the development of medical technology, wireless ultrasound device has emerged as a new and innovative diagnostic and therapeutic tool for interventional ultrasound. Under the guidance of ultrasound equipment, fine needle puncture directly reaches the lesion area to perform corresponding operations such as aspirating cyst fluid, injecting drugs or taking out lesion tissues for pathological biopsy, which can relieve clinical symptoms and clarify tumor nature.
In addition to the many advantages of minimally invasive puncture, safety, painlessness, and outpatient treatment, interventional ultrasound with a portable ultrasound probe is easy to move and can be punctured at the bedside when necessary. Due to being punctured under real-time dynamic monitoring, It is not affected by small lesions and organs with large mobility, and can display the internal situation of the puncture process synchronously, with high accuracy and fewer complications, relatively safe compared to clinical surgery.
Interventional wireless ultrasound technology is a new technology developed on the basis of ultrasound imaging to further meet the needs of clinical diagnosis and treatment. As a branch of modern ultrasound medicine, it was officially established at the World Interventional Ultrasound Academic Conference held in Copenhagen in 1983. The main feature is that under real-time ultrasound monitoring or guidance, various puncture biopsies, X-ray imaging, suction, catheterization, drug injection treatment, energy input, etc. can be completed, which can avoid some surgical operations and achieve results comparable to surgical operations.
It can improve accuracy by puncturing under real-time wireless ultrasound monitoring.
It has small damage, fewer complications, and is relatively safe.
Because it is punctured under real-time dynamic monitoring, it is not affected by small lesions and organs with large mobility and can display the internal situation of the puncture process synchronously.
It is easy to operate, with low cost, strong repeatability, and high practical value.
Portable B-ultrasound equipment is easy to move and can be punctured at the bedside when necessary.
At present, ultrasound intervention technology has been widely valued and applied, such as ultrasound-guided: biopsy of tissues or cytology in various parts of the body; puncture and sclerotherapy of various cysts such as hepatic cysts, renal cysts, and ovarian cysts; drug injection sclerotherapy of vascular malformations; drainage tube placement for effusion and abscess; PTCD surgery; thermal ablation (radiofrequency, microwave) or chemical ablation therapy for tumors in liver, kidney, lung and other parts; radiofrequency ablation of thyroid nodules and parathyroid glands; radiofrequency or microwave ablation of uterine fibroids; minimally invasive rotary cutting surgery for breast tumors; radioactive particle implantation for tumors; peripheral nerve intervention. In the future, wireless interventional ultrasound will continue to develop towards the direction of cardiac, vascular, and orthopedic intervention.
