I. Minimally invasive technique of fluorescence contrast ETS Research shows that there is often variation in the relationship between the position of the thoracic sympathetic ganglion and the corresponding ribs. Since the traditional technique can only see the sympathetic nerve chain and not the specific sympathetic ganglion, the traditional surgical treatment is likely to affect the treatment effect because of the variation of the sympathetic ganglion position. Fluorescence contrast ETS minimally invasive technique is currently an advanced technique in the clinical treatment of hand sweating, and has been a hot spot of research in many surgical fields in recent years. This technique is fluorescence staining by non-radioactive, non-toxic fluorescent contrast agent, which can quickly, accurately and clearly observe the direction and distribution of the thoracic sympathetic ganglion covering the wall pleura and connective tissue with its variant nerve, facilitating the differentiation of other normal tissue structures around it, avoiding the presence of omissions in the treatment, thus achieving safer, finer and more complete regulation of the treatment, avoiding This allows for safer, finer, and more complete treatment, avoiding damage to other nerves and normal tissues, providing more accurate treatment results, and greatly reducing postoperative complications of hand sweating, thus benefiting more patients with hand sweating. The safety and efficacy study of fluorescence imaging ETS minimally invasive technique in hand sweating has been presented at the 13th Annual International Sympathetic Surgery Conference, the 33rdEACTSAnnualMeeting, and other top thoracic surgery conferences in the world, and the results were selected for the 58th Annual STS Conference in 2022. According to the report, fluorescence imaging technology is safe and effective in the surgical treatment of hand sweating, and the study can assist doctors in performing minimally invasive ETS surgery to provide more accurate positioning, which can make the distribution of the target sympathetic ganglion visible and facilitate precise intraoperative operation. The whole process is fast, safe and efficient, not only laying a solid foundation for better treatment results, but also helping to further build a precise clinical treatment system for hand sweating, which was highly recognized and affirmed by the international counterparts present. This marks another firm step forward in the development of hand sweating clinical diagnosis and treatment technology.
