Abstract:
A memory metal optical fiber puncture needle tubing includes an optical fiber, a body tube, a metal casing and a split-shaped needle. The optical fiber has a body portion and a head portion. The head portion has a cylindrical head portion and a tapered head portion. The body tube surrounds the body portion. The metal casing is wrapped around the cylindrical head portion. The split-shaped needle is made of memory metal surrounding a periphery of the tapered head portion. The split-shaped needle has a plurality of tapered petals. When a temperature of the split-shaped needle is T0, the tapered petals are in a closed state such that the split-shaped needle is conical. When the temperature of the split-shaped needle is T1, the tapered petals are in an opened state such that the tapered head portion of the optical fiber is exposed.

Claim (Index 2):
The memory metal optical fiber puncture needle tubing according to  claim 1 , wherein\n the metal casing has an inverted-tooth structure along a length of the metal casing, the inverted-tooth structure having first surface facing a tapered head portion side of the optical fiber and a second surface facing a body portion side of the optical fiber, the first surface being at a first angle with respect to the cylindrical head portion that is less than a second angle of the second surface with respect to the cylindrical head portion so that the metal casing has a smaller resistance when advancing toward the target through a body as compared to a larger resistance that the metal casing has when retreating away from the target through the body, thereby effectively reducing an amount of thrust required for puncturing the body, the body tube is a spiral tube comprising a plurality of spiral coils wrapped around the body portion such that the body tube has a spiral structure having spiral kerfs formed by laser and a length of the body tube is 1 to 2 m.
