At the first national gynaecology application class for interventional ultrasound technology held recently, experts believe that with the continuous application of various new technologies, ultrasound-guided interventional examination and treatment will become an important means of diagnosis and treatment of many gynecological diseases.
According to Prof. Zhang Jing, the director of the Ultrasound Medical Committee of the Chinese Academy of Ultrasound Medical Engineering and the director of the Department of Ultrasound, the First Affiliated Hospital of the General Hospital of the People's Liberation Army, modern interventional ultrasound technology can perform histological biopsy on some female pelvic masses under ultrasound guidance. The pathological nature of the mass provides accurate data and information for clinical diagnosis and treatment. For example, uterine fibroids, the traditional treatment method is mainly surgical removal of the uterus, and now can be treated by ultrasound-guided microwave ablation or high-intensity focused ultrasound, that is, under the precise guidance of ultrasound, an outer diameter of only 1.9 mm The microwave needle directly punctures the lesion, and through the local heat energy, the fibroid tissue undergoes irreversible coagulation, degeneration, necrosis, and is finally absorbed or discharged by the body. The technique has little or no effect on the myometrial structure and ovarian function, and can preserve the integrity of the reproductive organs, does not affect the regulation of female endocrine, and maintains the normal physiological cycle and mental health of women.

Common medical masks are used to block spouts exhaled from the oral cavity and nasal cavity, and can be used for one-time hygiene care in ordinary medical environments with the lowest protection level. It is suitable for general hygiene care activities, such as sanitary cleaning, liquid distribution, cleaning bed units, etc., or the blocking or protection of particles other than pathogenic microorganisms such as pollen.
Conforms to the relevant registered product standard (YZB), generally lacks the filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than medical surgical masks and medical protective masks, only reaching 20.0% for 0.3Î¼m diameter aerosols -25.0% protection effect, can not reach the filtration efficiency of particles and bacteria, can not effectively prevent pathogens from invading through the respiratory tract, can not be used for clinical invasive operations, nor can it protect particles and bacteria and viruses, only limited to dust particles Or aerosol plays a certain mechanical barrier.
1. Carefully cover the mouth and nose with a mask and fasten it to minimize the gap between the face and the mask;
2. Avoid touching the mask when using it-after touching the used mask, for example to remove or clean the mask, wash your hands with soap and water or use alcohol hand sanitizer;
3. After the mask is wet or contaminated with moisture, replace with a new clean and dry mask;
4. Do not reuse disposable masks. Disposable masks should be discarded after each use.
