Sweaty hands are mainly related to the individual’s sympathetic nerves. Sweat from the hands is mainly sweat secreted by the small sweat glands, which are mainly regulated by the sympathetic nerves. Fluorescence visualization ETS minimally invasive technology is currently an advanced technology in the clinical diagnosis and treatment of hand sweating, and is also a research hotspot in many surgical fields in recent years. The technique is based on fluorescent staining with non-radioactive, non-toxic fluorescent contrast agent, which can quickly, accurately and clearly observe the direction and distribution of the thoracic sympathetic ganglion and its varicose nerves covering the wall pleura and connective tissues, so as to easily differentiate the other normal tissue structures in the surrounding area, avoiding omission in the treatment, thus achieving safer, finer, and more complete adjustment of the treatment, avoiding damage to other nerves and normal tissues, and avoiding damage to the other nerves and normal tissues. The treatment is safer, finer and more complete, avoiding damage to other nerves and normal tissues, providing more accurate diagnosis and treatment results, and greatly reducing the postoperative complications of sweaty hands, thus benefiting more sweaty hands patients.
