Conventionally, epidural anesthesia or insertion of a catheter is an anesthetic procedure which is performed by inserting a special needle such as a Tuohy needle into the spinal column for surgery, pain treatment and management. In the conventional procedure, the surgeon may find an appropriate point for Tuohy needle and insert the needle through the skin, then a syringe tube is put on the back of the needle so that the air is continuously injected to make the surgeon feel resistance. When the needle is advanced to enter the epidural space, all resistance is lost, and rather, a sound pressure is generated. At this point, the surgeon recognizes that the needle has entered the epidural space, and stops the advance of the needle and injects the drug. In the detection by this pressure sensor, the puncture sting is removed from the puncture needle before entering the epidural space, and the pressure sensor is attached to the epidural space, so that the tip of the puncture needle may be clogged by muscles. Also, an error that cannot be detected by the pressure sensor may be generated, thereby causing a reliability issue. The present invention relates to an epidural cortex cognition system that supports epidural anesthesia. The epidural cortex cognition system that supports epidural anesthesia visually recognizes the moment when an injection needle enters an epidural space, according to a change in an image inputted through an optical fiber at the time of entry into an epidural space in epidural anesthesia.COPYRIGHT KIPO 2017종래에 있어서 경막외 마취(epidural anesthesia) 또는 카테타의 삽입은 천자 바늘(Tuohy needle)이라는 특수한 주사바늘을 척추간으로 삽입하여 행하는 마취술로 수술, 통증 치료 및 관리에 사용되는 시술법이다. 기존의 시술방법은 먼저 적절한 지점을 찾아 천자 바늘을 피부를 통하여 삽입한 후 바늘 뒤에 주사관을 달아 계속 공기를 주입하면서 여기에 걸리는 저항을 느끼며, 바늘을 전진하여 경막외강에 들어가게 되면 모든 저항이 소실되고 오히려 음압이 걸리게 되며, 이때 바늘이 경막외강(epidural space)에 들어갔음을 인지하고 바늘의 진행을 멈추고 약물을 주입하는 등의 조작을 하게 된다. 이 압력센서에 의한 탐지는 격막외강에 진입하기 전에 천자바늘에서 천자침을 제거하고 압력센서를 부착하여 격막외강까지 진입시키기 때문에 천자바늘 끝이 근육 등에 의해 막힐 염려가 있으며 압력센서에서 감지되
