In the applied research of nanomaterials in photo-thermal therapy and based on the understanding of the principle of photo-thermal therapy and its medical equipment, this paper analyzes nanomaterials used for photo-thermal therapy, establishes model by the use of comprehensive evaluation method and selects nano-materials that are suiTable for photo-thermal therapy, namely, carbon nanomaterials and precious metal nano-materials. In addition, this paper analyzes the importance of human surgical health by the use of photo-thermal therapy and gives considerations from three aspects, that is, the surgical equipment health, the operating room hygiene and the medical health. This paper also establishes a mathematical model through correlation analysis and credibility analysis, thus emphasizing the necessity of surgical health.Key words: photo-thermal therapy / nanomaterials / human surgery / hygienic problem / mathematical model
