Six advantages of lumpectomy thyroid surgery: 1. Image magnification: the tiny neurovascular can be clearly seen, which is equivalent to doing surgery under a magnifying glass. 2. Accurate anatomical level: with inflation, it is easy to find lax gaps for bloodless separation. 3. Accurate identification of nerves and parathyroid glands: with high definition, the nerves are in the characteristic silvery-white cords and the vascular network of parathyroid glands is very clear and easy to find and confirm. 4, meticulous and clear observation: the light can be adjusted in strength and weakness, and the lens can be adjusted near and far and rotated in multiple angles, which is very conducive to the detailed observation of tissue structure. 5.Precise vascular treatment: using advanced ultrasonic knife to cut off blood vessels bloodlessly one by one, the tissue structure inside the wound will not be contaminated by blood. 6.No scar on the neck: no cut on the neck, cut on the chest wall or armpit, oral cavity, etc. The incision is small and hidden.
