Abstract

In the present invention, optical fiber is used for emitting or irradiating laser light in a blood vessel. When the optical fiber enters the blood vessel, the sharp end of the optical fiber is caught by the vessel wall, The glass tube slides through the vessel wall and can easily pass through it. The laser beam is emitted in a direction in which the laser beam proceeds straight from the end, and a laser beam is irradiated inside the blood vessel. At the same time, a laser beam This is to prevent the penetration of blood vessel wall during laser treatment.

Description

[0001] This invention relates to a laser optical fiber for use &

In general, when the fiber enters into the blood vessel and goes down or down, the tip is sharp and it is caught by the blood vessel wall, which makes it difficult to proceed. This makes it possible to easily move the optical fiber into the blood vessel, The laser beam is radiated in a circular shape to form a circular groove in the optical fiber remaining inside the glass tube to prevent the blood vessel wall from passing through the blood vessel wall, And it is effective to shrink vessels quickly and easily.

In using the fiber inside the vein, using only ordinary fiber

It is very inconvenient to enter the inside of blood vessels and sometimes it can not enter. To improve this, there is a phenomenon that when the light is emitted toward the wall of the blood vessel as the laser beam goes straight from the end, the blood vessel wall penetrates This is improved by inserting a glass tube at the end of the optical fiber and irradiating the end of the glass tube like a pencil end directly, and the glass tube prevents the end of the optical fiber from touching the blood vessel wall In the groove formed in the optical fiber inside the glass tube, the laser beam is radiated into the 360 degree circular shape and irradiated directly to the vessel wall.

To prevent the tip of the optical fiber from touching the blood vessel wall, the end of the optical fiber is in the glass tube so that the vessel wall is not blocked and the laser beam is emitted from the optical fiber inside the glass tube.

A glass tube is inserted at the end of the optical fiber so that the end of the optical fiber does not touch the vessel wall, and a circular groove is formed in the optical fiber inside the glass tube so that the laser beam is irradiated from the inside of the glass tube to the outside.

By inserting the glass tube at the end of the optical fiber, the glass tube prevents the end of the optical fiber from touching the vessel wall, so that the optical fiber can smoothly enter into the blood vessel, and the laser beam is emitted in a round shape in the circular groove in the optical fiber inside the glass tube When irradiated directly to the vessel wall, blood vessel contraction occurs very quickly and laser energy is also lowered.

Representative figures are drawings showing the shape of the present invention
Figure 1 is a schematic representation of the present invention,

After stripping off the fiber at the end of the optical fiber and pushing the optical fiber into the glass tube, the end of the optical fiber is positioned at the end of the glass tube and the stainless steel is inserted at the back of the glass tube to bond the optical fiber and the glass tube by bonding. And the tip of the glass tube is rounded so that it can smoothly enter into the blood vessel. A circular groove is formed in the optical fiber inside the glass tube and the laser beam is emitted from the glass tube to the outside of the glass tube, Direct laser beam is irradiated.
