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 1):
A memory metal optical fiber puncture needle tubing, comprising:\n an optical fiber comprising a body portion and a head portion, the head portion comprising a cylindrical head portion and a tapered head portion, the tapered head portion having a tapered diameter that decreases as a distance away from the cylindrical head portion increases; a body tube surrounding the body portion; a metal casing wrapped around the cylindrical head portion; and a split-shaped needle made of memory metal surrounding a periphery of the tapered head portion, wherein the metal casing is fixedly connected with the split-shaped needle, and the split-shaped needle is composed of a plurality of tapered petals, when a temperature of the split-shaped needle is T0, each of the tapered petals in the split-shaped needle made of memory metal is in a closed state such that the split-shaped needle with the tapered petals in the closed state exhibits a conical structure within which the tapered head portion of optical fiber is accommodated, when the temperature of the split-shaped needle is T1, each of the tapered petals in the split-shaped needle made of memory metal is in an opened state such that the tapered head portion of the optical fiber is exposed to enable light to be directly irradiated onto a target, and when each of the tapered petals is in the closed state, adjacent sides of two adjacent tapered petals overlap in a radial direction with respect to a central axis of the tapered head portion.
