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 6):
The memory metal optical fiber puncture needle tubing according to  claim 11  wherein\n the body portion of the optical fiber is coated with a body coating for preventing light from being emitted from a periphery of the body portion of the optical fiber, and \n the tapered head portion of the optical fiber has a refractive index of 1.45 to 1.55 and a taper angle with respect to the central axis of 7\u00b0 to 25\u00b0.
