Conventionally, when treating an affected area in a body cavity with laser light using an endoscope, a fiber probe was inserted into the channel of the endoscope and the laser light was sent through the fiber probe to perform the treatment. However, according to this method, it is necessary to take the fiber probe for light transmission into and out of the channel, which is troublesome and does not allow quick treatment. In addition, there were drawbacks such as the fiber probe breaking when the fiber probe was inserted or removed.

This endoscope distal end 1 is formed at the distal end of an insertion section 2. As shown in FIG. 1, an observation window 3, an illumination window 4, a forceps port 5, an air/water supply nozzle 6, and an irradiation window 7 are formed on the distal end surface of the endoscope distal end 1. The observation window 3 has an objective lens 7 as shown in FIG.
and an objective optical system 9 consisting of an imaging lens 8. Further, a solid-state image sensor 10 made of, for example, a CCD is disposed opposite to the image-forming position of the objective optical system 9, and is adapted to receive an observation image on the imaging surface of the solid-state image sensor 10 and convert it into an electrical signal. . The signal line 1 that transmits this electrical signal
1 is a shield tube 11 disposed inside the insertion section 2
a and is connected to a monitor 12 outside the endoscope. The tip of a light guide (not shown) is optically connected to the illumination window 4. This light guide reaches an external electric light source device 13 through the insertion portion 2 and is connected thereto. And the electric light source device 13
Normal illumination light is guided from the illumination window 4 to illuminate the observation field inside the body cavity. Further, a forceps channel (not shown) is connected to the forceps port 5. Further, an air/water tube (not shown) is connected to the air/water nozzle 6, and water or air is sprayed from the air/water nozzle 6 toward the observation window 3.

きる。 Therefore, when the operation switch 19 for laser treatment of the electric light source device 13 is turned on, the semiconductor laser element 1
4 oscillates, and a focused beam is emitted through the cover glass of the irradiation window 7, allowing laser irradiation treatment to be performed. On the other hand, when performing infrared observation rather than laser irradiation treatment, the semiconductor laser element 14 is removed from the terminals 16, 16 and replaced with a third
When the infrared lamp 15 shown in the figure is attached and the operating switch 19 for the infrared lamp is turned on, the infrared lamp 15 lights up and observation using infrared light is possible.
