Abstract

Provided herein is a light transmitting cable for laser treatment, the cable including a first optical fiber configured to generate a high energy particle by a laser beam transmitted from a light source and to transmit the high energy particle to a target; and an image transmitting cable configured to transmit an image surrounding the target, thereby being capable of treating a tumor with relatively low power output while identifying a location of the tumor.

First claim

What is claimed is:

1. An endoscopic light transmitting cable comprising:
at least one first optical fiber configured to transmit light from a light source to generate a laser beam;
a lens configured to refract the laser beam transmitted by the first optical fiber;
a thin film positioned proximate to a focal distance of the laser beam refracted by the lens and configured to generate a high energy particle that is accelerated toward a target tissue; and
an image transmitting cable configured to transmit an image surrounding the target tissue,
wherein the image transmitting cable is disposed in a first lumen and the at least one first optical fiber is disposed in a second lumen adjacent to the first lumen.

2. The light transmitting cable according to claim 1 ,
wherein the laser beam is received from a femto-second, pico-second, or nano-second laser source coupled to the transmitting cable, and
wherein the target tissue is a tumor.

3. The light transmitting cable according to claim 1 ,
wherein the first optical fiber comprises a lens for focusing the transmitted laser beam.

4. The light transmitting cable according to claim 1 , further comprising:
a blocking plate disposed with a certain distance from the thin film of the first optical fiber in order to block the high energy particle generated by the first optical fiber from proceeding beyond the target tissue.

5. The light transmitting cable according to claim 1 ,
wherein the thin film comprises a hydrogen atom or carbon atom, and is configured to generate, by the laser beam, a proton as the high energy particle.

6. The light transmitting cable according to claim 1 ,
wherein the image transmitting cable is a second optical fiber cable configured to transmit visible ray reflected from the target tissue.

7. The light transmitting cable according to claim 1 ,
wherein at one end of the image transmitting cable, a camera for photographing the target tissue is mounted, and the camera is configured to convert a photographed image into an electric signal and transmit the image through the image transmitting cable.

8. An endoscopic laser system comprising:
a laser light source configured to generate a femto-second, pico-second, or nano-second laser beam; and
a light transmitting cable including:
a first lumen including at least one first optical fiber configured to transmit light from a light source to generate a laser beam;
a lens configured to refract the laser beam transmitted by the first optical fiber;
a thin film positioned proximate to a focal distance of the laser beam refracted by the lens and configured to generate a high energy particle that is accelerated toward a target tissue; and
a second lumen adjacent to the first lumen and including an image transmitting cable configured to transmit an image surrounding the target issue.

9. The laser system according to claim 8 ,
wherein the image transmitting cable includes an endoscope configured to observe an area surrounding the target tissue, the target tissue being a tumor.

10. The laser system according to claim 9 ,
wherein at one end of the image transmitting cable, a camera for photographing an image surrounding the target tissue is provided, and the image transmitting cable is configured to transmit an electric signal generated from the camera.

11. The laser system according to claim 9 ,
wherein the image transmitting cable is an optical fiber cable configured to transmit visible ray entering from an area surrounding the target tissue.

12. The laser system according to claim 8 ,
further comprising a blocking plate provided at one end of the light transmitting cable, and configured to block the high energy particle generated by the first optical fiber from proceeding beyond the target tissue.

13. The laser system according to claim 12 ,
wherein the blocking plate is configured such that its distance from the light transmitting cable is adjustable.

14. The laser system according to claim 8 ,
wherein the thin film comprises a hydrogen atom or carbon atom, or both, and is configured to generate a proton as a high energy particle.

15. The light transmitting cable according to claim 4 , wherein the blocking plate is disposed at one end of the light transmitting cable, the blocking plate being movable to adjust a distance between the blocking plate and the thin film and configured to block the high energy particle generated by the first optical fiber from proceeding beyond the target tissue.

16. The light transmitting cable according to claim 1 , wherein the at least one first optical fiber, the lens, and the thin film are arranged to deliver the high energy particle directly to the target tissue imaged by the image transmitting cable.

17. The light transmitting cable according to claim 8 , wherein the at least one first optical fiber, the lens, and the thin film are arranged to deliver the high energy particle directly to the target tissue imaged by the image transmitting cable.
