Micro-stovepipe surgery adopts high-tech microsurgery technology to selectively cut off the nerve controlling gastrocnemius muscle, so that gastrocnemius muscle loses control, and the muscle immediately becomes thinner, flatter and softer after operation, and immediately achieves the effect of stovepipe acupuncture. At the same time, the muscle loses the nutrient supply of nerve, so that gastrocnemius muscle gradually shrinks and becomes smaller, and the best stovepipe effect can be achieved in 3-6 months and maintained permanently.
