Abstract

The present invention relates to a capsule endoscope for photodynamic and sonodynamic therapy. The present invention comprises: an endoscope body; a light and ultrasonic wave irradiation portion provided on the outer surface of the endoscope body and irradiating light of different wavelengths and ultrasonic waves; and a photodynamic and sonodynamic therapy portion connected to the outer surface of the endoscope body and comprising a material for photodynamic and sonodynamic therapy, wherein the photodynamic and sonodynamic therapy portion can be activated by the light and ultrasonic waves irradiated from the light and ultrasonic wave irradiation portion. According to the present invention, the capsule endoscope can treat local bacterial infection, or diabetes, malignant diseases, chronic colitis and the like caused by a change in the number and type of intestinal floras while passing through the body in addition to carrying out diagnosis, which is the inherent function of a capsule endoscope, and thus there is no need for additional treatment and a patient can comfortably receive therapy.

Claims

1. A capsule endoscope for a photodynamic and sonodynamic therapy, comprising:

an endoscope body;

light and ultrasonic wave radiators disposed surrounding the surface of the endoscope body and radiating light and ultrasonic waves with different wavelengths; and

photodynamic and sonodynamic treaters connected to the surface of the endoscope body and containing substances for a photodynamic and sonodynamic therapy,

wherein the photodynamic and sonodynamic treaters are activated by light and ultrasonic waves from the light and ultrasonic wave radiators.

2. The capsule endoscope of claim 1, wherein the photodynamic and sonodynamic treaters are connected to the endoscope body by connecting fibers that are decomposed at a pH condition in an intestine.

3. The capsule endoscope of claim 1, wherein the light and ultrasonic wave radiators are disposed like bands surrounding the surface of the capsule endoscope.

4. The capsule endoscope of claim 1, wherein the endoscope body has the shape of a cylinder or a rugby ball.

5. The capsule endoscope of claim 1, wherein the photodynamic and sonodynamic treaters have the shape of a microcapsule and a substance for the photodynamic and sonodynamic therapy is at least one selected from a group consisting of a light or ultrasonic sensitizer, an antibiotic, a nano-substance, and probiotics.

6. The capsule endoscope of claim 1, wherein cameras are disposed at the front and the rear of the endoscope body.

7. The capsule endoscope of claim 6, wherein the light and ultrasonic wave radiators and the cameras are controlled to be turned on/off from the outside of a human body.

8. The capsule endoscope of claim, a plurality of the capsule endoscopes for a photodynamic and sonodynamic therapy is connected by connectors.
