本考案はライトガイド繊維束を用いて体腔を照

る。 Generally, in an endoscope that illuminates a body cavity using a light guide fiber bundle, a light source such as a xenon lamp is disposed opposite to the end surface of the light receiving section connected to the light source device of the light guide fiber bundle. The light guide fiber bundle receives light output from the body cavity, thereby illuminating the body cavity.

つて冷却する構成だと、光源装置の大形化や複雑
化を招くという問題もある。 By the way, since the light receiving section of the light guide fiber bundle is heated by the heat from the light source, conventionally a fan is provided in the light source device and the light receiving section is air-cooled by this fan. . However, simply forming airflow inside the light source device using a fan has poor cooling efficiency, so when a high-output light source such as a xenon lamp is used, the end surface of the light receiving section may become hot. It may get heated and burnt out. Further, if the cooling is performed using a fan, there is a problem in that the light source device becomes larger and more complicated.

The purpose of this is to create an endoscope that can cool the light receiving section with a simple structure by providing a cooling fluid passage near the light receiving section of the light guide fiber bundle. It is about supplying.

る。 Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3. In the figure, reference numeral 1 denotes an insertion section made of a flexible tube or the like with an operating section 2 provided at one end. The operation section 2 is provided with a forceps insertion port 3 and an eyepiece section 4, and a flexible tube 5 connected to one end thereof. A connecting portion 7 having a cylindrical support portion 6 is provided at the other end of the flexible tube 5, and this connecting portion 7 is connected to a housing 9 of a light source device 8. A light source 10 such as a xenon lamp is provided in the housing 9 so as to face the end surface of the support section 6 , and the light output from this light source 10 is focused onto the end surface of the support section 6 by a reflecting mirror 11 . It's becoming like that.

The light guide fiber bundle 12 is guided into the flexible tube 5, and the other end thereof faces the end surface of the support section 6. Therefore, the light output from the light source 10 is transmitted from the end surface of the support section 6 to the light guide fiber bundle 12.
The light enters the insertion section 1 and is emitted from the distal end of the insertion section 1. The support portion 6 also includes a light source 1.
A cooling fluid passage 13 that cools the light guide fiber bundle 12 heated by the heat released from the
is formed. That is, this passage 13 is
an inlet section 14 to which tap water, for example, is supplied as a fluid; an outgoing section 15 along the light guide fiber bundle 12;
The light guide fiber bundle 12 is located close to the end surface of the support portion 6.
An annular portion 16 surrounding the outer periphery of the light guide fiber bundle 1
It is formed from a return part 17 which is provided symmetrically to the above-mentioned forward part 15 with 2 as the center, and an outlet part 18 from which the tap water that has passed through each of the above parts is discharged.

ら、構成が極めて簡単である。 Therefore, in the above configuration, when the light source 10 is turned on when observing the body cavity with illumination, the light source 10
The support portion 6 is heated by heat radiation from the support portion 6 . However, in the present invention, a passage 13 is formed in the support portion 6, through which tap water having a large heat absorption capacity flows as a cooling fluid. Therefore, the tap water flowing through the passage 13 cools the entire support part 6, especially the end face of the support part 6, which is at the highest temperature, well by the annular part 16 of the passage 13, so that the support part 6 does not become abnormal. There is no possibility that the light guide fiber bundle 12 in the portion supported by the support portion 6 will be burned out due to such high temperature. In other words, since the light source 10 with a sufficiently large output can be used, the body cavity can be illuminated in a state that makes it easy to observe. Moreover,
According to the present invention, the passage 13 is formed in the support part 6,
Since tap water is simply supplied to this passage 13, the configuration is extremely simple.

Hereinafter, explanation will be given based on the drawings, but in order to simplify the explanation, the same parts as in the above-mentioned embodiment will be given the same symbols and the explanation will be omitted. That is, the operation unit 2 is provided with an air supply water operation valve 19 and a suction operation valve 20. Further, the connecting portion 7 is provided with an air supply port 21 connected to an air supply pump, a water supply port 22 connected to a water supply pump, and a suction port 23 connected to a suction pump. The air supply port 21, the water supply port 22, and the suction port 23 are connected to the air supply water operation valve 19 and the suction operation valve 20 through an air supply path 24, a water supply channel 25, and a suction path 26. Then, by operating the air supply water operation valve 19, air and water are ejected from the distal end of the insertion section 1, and the objective lens (not shown) provided at the distal end of the insertion section 1 can be cleaned. By operating the suction operation valve 20, mucus and wash water from the body cavity can be suctioned.

ことができるなどの効果を奏する。 As described above, the present invention has a support part facing the light source in the light source device, and the cooling fluid flows into or out of the connection part where the end of the light guide fiber bundle is disposed on the support part. At the same time, a passage is provided on the outer periphery of the light guide fiber bundle of the supporting part that communicates with the opening and allows the cooling fluid to flow out or in from outside the connecting part. Therefore, the light receiving portion of the light guide fiber bundle can be cooled well and reliably.
In addition, the configuration is simpler than the conventional means of cooling using a fan, and there is no need to increase the size of the entire endoscope, and the cooling fluid can be provided near the light receiving part of the light guide fiber bundle. Since the cooling efficiency is improved by flowing through the passage, a high output light source can be used for illumination without burning out the light guide fiber bundle. In other words, it is possible to brightly illuminate the body cavity so that it is easy to observe it.
