The treatment probe emits electromagnetic waves through the mainframe, forming a focused magnetic field at the tip of the needle tip and causing thermal effects on the surrounding contact tissue, instantly causing high temperature coagulation and denaturation of the tissue, which can be used for ablation of the sweat gland layer of the axillary tissue due to the controlled range of coagulation spherical points and reliable orientation. Achieve atrophy and necrosis of sweat glands. Compared with the traditional surgical removal of sweat glands, the thermal coagulation knife treatment of axillary odor has a safer, simpler and faster method. And there is no damage to the treatment needle tract, the post-operative efficacy is reliable, truly non-invasive treatment, the advantages of short recovery time. Electrocoagulation needle technology has now been officially approved by the state, is a patented thermal cohesive focus technology, needle point fixed ablation; has the following advantages: 1, focus directly to the sweat gland layer, the curative effect is remarkable; 2, precise temperature control probe, skin needle channel without damage; 3, easy and rapid operation; 4, rapid recovery, no marks, scar after surgery, does not affect work and study. This treatment is for patients with various degrees of axillary odor and hyperhidrosis; for patients who are afraid of surgery and postoperative scarring and require a short recovery period; also for patients who have relapsed after applying other methods of treatment, and for some patients who require treatment for less invasive axillary odor or hyperhidrosis. Treatment mechanism: In the axillary hair area, the number and volume of subcutaneous sweat glands of all sizes are ablated to the maximum, and at the same time, the thermal damage to the needle access and skin surface can be effectively reduced during the operation, and the postoperative clinical effect is a reduction of sweat and disappearance of odor or very light. Postoperative precautions: Give oral antibiotics for one week. Apply 2% gentian violet solution to keep the surgical area dry, prohibit scratching, prohibit water for a week, minimize upper limb activities do not strenuous exercise, if there is exudate or skin damage, available 95% medical alcohol wipe after ice, 4 weeks after surgery review.
