The present disclosure relates to a calculus removing device which is used in the medical field. More particular, the present disclosure relates to a calculus removing device which has a lithotripsy probe capable of simultaneously destructing and removing the calculus formed in the human body regardless of the size of the calculus by optionally using attractivity or electricity through a lithotripsy probe. According to an embodiment of the present disclosure, a calculus removing device includes a first tube having an interior region; a second tube which is inserted in to the interior region of the first tube so as to move in the interior region; a capture means of which one end is coupled to an end of the second tube, and which is led-in into the interior region of the first tube corresponding to the moving of the second tube, allowing capturing and fixing a calculus; a lithotripsy probe which is inserted into an interior region of the second tube and contacts with the calculus fixed by the capture means, allowing applying an electric shock; and a handle which is coupled to an end of the first tube, and moves the second tube and the lithotripsy probe independently.

Caculus removing device

The present invention relates to an endoscope. The present invention may include an endoscope main body; and a guide cap that is mounted to be fixed to a front end of the endoscope main body when inserting the endoscope main body into a human body and slides to protrude toward the front of the endoscope main body when withdrawing the endoscope main body inserted into the human body. An object of the present invention is to facilitate insertion of the endoscope by freely varying a length of the cap from the front end of the endoscope, and to enhance the detection rate of polyp.

Endoscope

There is provided a therapeutic apparatus for photodynamic therapy that includes a hollow tube inserted into a living body; an unfolding part that is coupled to one end of the tube and is unfolded; a light irradiation part that is disposed in the unfolding part to irradiate light; and an operating part that is coupled to the other end of the tube to unfold the unfolding part, wherein the light irradiation part irradiates light when the unfolding part is unfolded. The therapeutic apparatus for photodynamic therapy according to the present disclosure allows irradiation of light by unfolding tissues of the curved portion in the living body, using an unfolding part capable of being unfolded depending on the user's selection and the light irradiation part coupled to the unfolding part, there is an effect of allowing the use of the photodynamic therapy even in a portion that cannot be conventionally treated using the photodynamic therapy.

Therapeutic apparatus for photodynamic therapy for investigating curved portion

A capsule endoscope for photodynamic and sonodynamic therapy is disclosed. The capsule includes: 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. 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.

Capsule endoscope for photodynamic and sonodynamic therapy

Effective Photodynamic therapy (PDT) againstis provided using a composition including chitosan and tetracycline.
