Abstract:
본 발명의 실시예에 따른 신경 탐침 인터페이스는, 광원; 및 일단부는 상기 광원에 연결되고 타단부는 신경에 광 자극을 가하기 위해 탐침 대상인 신경 내부로 삽입되는 탐침부로 마련되며, 코어 및 상기 코어를 부분적으로 감싸는 클래드를 갖는 광도파관;을 포함하며, 상기 탐침부는 상기 신경으로의 삽입을 위한 원뿔 형상의 코어부재로 형성되며, 상기 클래드는 상기 코어부재를 제외한 상기 광도파관의 나머지 영역의 적어도 일부분을 감쌀 수 있다. 본 발명의 실시예에 따르면, 탐침부의 코어부재가 클래드가 제거된 원뿔 형상을 가짐으로써 신경 탐침의 용이성을 확보할 수 있으면서도 코어부재와 접촉되는 물질 간의 굴절률 차이에 기초하여 신경에 대한 탐침부의 접촉 유무를 정확하게 판별할 수 있음은 물론 탐침부의 삽입 깊이도 미세하게 조정할 수 있다.
