The present invention relates to an energy transmission module for a vaginal canal treatment apparatus, a method for controlling same, and a treatment method using same according to the present invention allow transmission of energy by means of insertion into the vaginal canal and expansion of the vaginal canal, and thus allow treatment by selectively or complexly generating denaturation such as coagulation and ablation over a large area in a short time, allow one-shot treatment, and allow treatment of an area with folds. Therefore, the efficiency and accuracy of the treatment can be enhanced. Since the tissue in the vaginal canal can be treated even without a surgical operation, user's pain and discomfort can be minimized.
