Outline of Final Research Achievements

Background) Since current surgical tissue repair methods cause injuries and overpressure by suture, complete remodeling of viable tissue is impossible. The tissue fusion technique without damages is hoped.
Purpose) This study is aimed to clarify the mechanism of interdigitation by laser energy between collagen fiber, and develop the technique of tissue repairing and fusion without injuries. Results) The bundle of collagen fiber was loosened and was swollen at 45℃. The pressure proof was significantly strong in Group A and interdigitation of different collagen fiber was observed.
