Medical energy irradiation apparatus
First Claim
1. A medical energy irradiation apparatus for generating energy and irradiating tissues of a living body with the generated energy comprising:
- an inserting portion which is inserted into the living body;
an endoscope provided in an interior of said inserting portion and being insertable along a longitudinal direction of said inserting portion;
an emitting portion provided in the interior of said inserting portion for irradiating tissues of the living body with the energy;
emitting portion moving means for moving said emitting portion along the longitudinal direction of said inserting portion continuously; and
emission angle-changing means for changing an emission angle of said emitting portion continuously such that the generated energy irradiates an irradiation target position;
wherein said inserting portion has a side-observation window and at least one position mark arranged along the longitudinal direction in an interior of said inserting portion, said side-observation window being arranged at a side portion of said inserting portion and used for observing tissues of the living body by said endoscope and irradiating tissues of the living body with the energy by said emitting portion, said at least one position mark being used for determining the irradiation target position of tissues of the living body to be irradiated with the energy based on a position of tissues of the living body observed through said side-observing window by said endoscope and a position of said at least one position mark observed by said endoscope.

Abstract
To provide a medical energy irradiation apparatus which permits easy and accurate establishment of a site of tissues of a living body targeted for irradiation with energy, when doctors use the medical energy irradiation apparatus to perform a cure for a prostatic hyperplasia or the like. The doctors insert an applicator 110 of the medical energy irradiation apparatus to an urinary bladder 161 and fix an endoscope 135 near to an entrance of an urethra. In this arrangement, when observing with the endoscope (135), a seminal colliculas 144 observed through a side-observation window 130 is observed toward a lower part of an observed image (schematic diagram) displayed on a display unit, and a positioning marker 140 in an interior of the applicator is observed toward an upper part of an observed image. The doctors can accurately determine a position to be irradiated with laser light from positions of the seminal colliculas 144 and the positioning marker 140 observed, and a direction of irradiation with laser light from a position of a direction marker 142, respectively.
