Wherever possible, the same reference numerals will be used to refer to the same elements throughout the specification, and a duplicated description thereof will be omitted. It will be understood that although the terms “first”, “second”, etc. are used herein to describe various elements, these elements should not be limited by these terms. These terms are only used to distinguish one element from another element.

FIG. 1is a side view illustrating schematically an optical fiber for producing heat according to an embodiment of the present invention,FIG. 2is a perspective view illustrating in detail an optical fiber11among the optical fiber for producing heat as shown inFIG. 1,FIG. 3is a front view illustrating the optical fiber for producing heat as shown inFIG. 1, andFIG. 4is a rear view illustrating the optical fiber for producing heat as shown inFIG. 1.

Referring toFIGS. 1 to 4, the optical fiber for producing heat according to an embodiment of the present invention is provided with an optical fiber11and a cloth12, which are arranged sequentially from inner side to outer side around a concentric circle, and a reflection tube13and a heat conduction tube14where the cloth12is peeled away among the optical fiber11. Meanwhile, the reflection tube13and the heart conduction tube14may be disposed variously.

The optical fiber11, as shown inFIG. 1, a first reflection type groove11a, a second reflection type groove11b, a first circular groove11c, a second circular groove11dand a remote end lie of the optical fiber.

In more detail, the optical fiber11is configured by the reflection type grooves and the circular grooves for producing heat, which are formed on a side of the optical fiber11, the thin and long remote end lie, the reflection tube13that wraps whole area corresponding to a side of the optical fiber11and a heat conduction tube14that covers whole outer peripheral surface thereof.

The laser beam is reflected continuously through the reflection tube13of a fixing substance to produce heat while the laser beam transmitted through the optical fiber11is not irradiated outside the heat conduction tube14corresponding to an outer wall of the reflection tube13of a fixing substance so that the produced heat is transmitted into blood vessel while the produced heat is maintained within a preset temperature range.

Here, the reflection tube13may be made of glass, reinforced glass, Pyrex, sapphire, ceramic, acryl or the like, and the reflection tube serves to maintain heat at a constant level by reflecting and refracting continuously heat in a length direction when laser beam is irradiated through the optical fiber11.

As a result, the laser beam that is irradiated using an optical fiber produces heat at the first reflection type groove11a, the second reflection type groove11b, the first circular groove11c, the second circular groove11dand an inner space of the reflection tube13along a whole length of the reflection tube13, not at one place of the remote end of the optical fiber as in a related art, thereby transmitting the heat into blood vessel.

As shown inFIGS. 1 and 2, the second circular groove11d, the first circular groove11c, the second reflection type groove11band the first reflection type groove11aare formed sequentially to be space each other between a rear end of the remote end11eamong the optical fiber11and a front end of the cloth12so that laser beam is irradiated to multi-directions.

Eventually, the heat is produced by the laser beam that is transmitted through the optical fiber11evenly at a side of the reflection tube13a section of which is a cylinder shape and at a front of the reflection tube a section of which is hemispheric.

Even though side effects are produced when irradiating laser to blood vessel to treat varicose vein according to a related art, the optical fiber for producing heat configured as described above according to the present invention does not irradiate directly laser beam into blood vessel of a human body but transmit heat thereto thereby to serve heat operation like high frequency to perform stably surgical operation.

Further, the heat within the reflection tube13is maintained at a constant level using the first reflection type groove11a, the second reflection type groove11b, the first circular groove11c, the second circular groove11dso that the side effects caused from excessive laser can be prevented.

When manufacturing the optical fiber for producing heat, a cloth12at one side of an optical fiber11is peeled away and the side of the optical fiber11is processed precisely while adjusting a horizontal angle around a central axis of the optical fiber11to form two or more of reflection grooves and circular grooves in a conical form, or at least two are processed by combining the reflection grooves and the circular grooves.

Meanwhile, it is shown inFIGS. 1 and 2that the first circular groove11cand the second circular groove11dare processed additionally in addition to the first reflection type groove11aand the second reflection type groove11b, however, the first circular groove11cand the second circular groove11dmay be replaced with the reflection type grooves such that the reflection grooves are disposed at equal angle around 360 degree of clockwise or counter-clockwise. On the contrary, the first reflection type groove11aand the second reflection type groove11bmay be replaced with the circular grooves.

After processing precisely the optical fiber11, the optical fiber11of which the cloth12is peeled away is enveloped by a reflection tube13and then the outside of the reflection tube13is wrapped by a heat conduction tube14to block laser beam from being irradiated outside thereby to produce heat within the reflection tube13. Here, the reflection tube13and the heat conduction tube14are bonded to prevent the reflection tube13from being detached.

The reflection tube13may be made of glass and the heat conduction tube14may be made of stainless, however, there is no limitation thereof, and thus the reflection tube13may be made of any materials having properties of transmission, reflection and refraction of light including laser beam and the stainless of the heat conduction tube14may be replaced with material of light block and heat conductive. In more detail, the reflection tube13is made mainly of glass, however, the reflection tube may be made of glass, reinforced glass, Pyrex, sapphire, ceramic, acryl or the like, and the heat conduction tube14may be made of stainless steel, tungsten, titanium, aluminum, aluminum alloy, copper, bronze, bronze alloy, cast iron or other metals, or nonmetallic material. Meanwhile, the reflection tube13may be made of transparent material, semitransparent material or opaque material through which channels are formed.

That is, an outer peripheral surface of the reflection tube13is wrapped by the heat conduction tube14to block the laser beam that is transmitted through the optical fiber11from being irradiated outside and a plurality of reflection type grooves or circular grooves are formed on a side of the optical fiber11where the cloth12is peeled away so as to transfer laser beam so that the heat is produced evenly by the laser beam along a length direction of the heat conduction tube14outside the reflection tube13.

Meanwhile, a diameter of the optical fiber may be from 0.1 mm to 100 mm, and frequency for transferring laser beam may be from 400 nm to 20000 nm and a length of the optical fiber11may be from 1 cm to 1000 cm.

Further, a total length of the reflection tube13and the heat conduction tube14may be from 1 mm to 500 mm, a diameter, inner diameter and outer diameter thereof may be from 0.001 mm to 1000 mm wherein a diameter of the reflection tube13is shorter than that of the heat conduction tube14, as shown inFIG. 1.

As an modified embodiment of the present invention, a section of the reflection tube13or the heat conduction tube14may be an oval shape, triangular shape or quadrangular shape in addition to a circular shape, and a shape of the remote end thereof may be a conical shape, a concave shape, triangular shape, quadrangular shape or digon shape at spherical geometrics in addition to hemispheric shape.

Meanwhile, a boding surface of the reflection tube13, the heat conduction tube and the cloth12may be blocked or opened.

According to an optical fiber for producing heat and a method for manufacturing the same, the optical fiber does not irradiate laser beam into blood vessel but transmit the laser beam thereto and serves as heat operation like high frequency so as to treat varicose vein, thereby improving side effects caused from irradiating directly into blood vessel according to a related art and performing stably surgical operation.

Further, according to an optical fiber for producing heat and a method for manufacturing the same a whole temperature outside the heat conduction tube is kept at a constant level through each of reflection type grooves or circular grooves or a combination thereof, thereby preventing side effects caused from excessive laser.
