Outline of Final Research Achievements

Non-breakable infrared optical fiber is required for laser endoscopic surgery.
In this study, Our group has tried to make hollow fiber based on nickel titanium pipe with an inner diameter of 530 μm as an infrared optical fiber that is “non-toxic”, “corrosion resistant”, “biocompatible”, adaptable to the movable range of the endoscope.
We have succeeded make a optical polymer coated silver hollow Ni-Ti fiber that can transmit Er: YAG laser light with excellent incision ability, CO2 laser light with hemostatic ability, and LD light for visually recognizing the irradiated part.

Academic Significance and Societal Importance of the Research Achievements

Minimal invasive medicine (最小侵襲治療)が叫ばれている医療現場において、レーザによる非観血的な治療は社会的な要求であり、それに関連する治療装置の開発は極めて社会的にもニーズが大きい。それと共に、高出力赤外レーザ光を安全かつフレキシブルに伝送する多機能性のある内視鏡用高信頼性・再利用性・高機能太径中空Ni-Tiファイバを実現することは、大きな意味を持つ。
