Problems solved by technology

[0003] In conventional capsule endoscopes, there is a disadvantage that after being inserted into the body cavity, the observation (photographing) window has a reduced imaging function due to adhesion of body fluids, etc. Observe the state of the affected part in the state that should be treated, and treatment cannot be performed, etc.
[0012] However, in this prior example, since the curved portion in which the normal curved piece is continuously provided in the longitudinal direction is formed, the total length becomes long, and there is a disadvantage that the insertability decreases when inserted into the patient's body.

Embodiment 1

[0069] Embodiment 1 of the present invention will be described with reference to FIGS. 1 to 18 .

[0070]As shown in FIG. 1 , an endoscope system 1 according to Embodiment 1 of the present invention is composed of the following parts: an endoscope 3 for inspecting the inside of a body cavity of a patient (not shown) lying on an examination bed 2; An air supply and water supply suction unit (abbreviated as AWS unit) 4, which can be freely detachably connected to the endoscope 3 to perform air supply, water supply and suction control operations; an endoscope system control device that performs control processing for the endoscope 3, etc. 5; observation monitor 6, which displays the endoscope image etc. generated by the endoscope system control device 5; Various remote operations. The operation remote controller 7 is detachably connected to, for example, a connector 9 of the AWS unit 4 via a connection wire 8 .

Embodiment 2

[0251] Next, Embodiment 2 of the present invention will be described with reference to FIGS. 19A to 21 .

[0252] Fig. 19A shows an endoscope 3B according to Example 2 of the present invention. In addition, FIG. 19B shows the front end side in FIG. 19A in a perspective view, thereby showing the internal structure of the front end side of the capsule part 22 .

[0253] This endoscope 3B is configured such that, instead of the four R-LEDs 39a, G-LEDs 39b, B-LEDs 39c, and IR-LEDs 39d as illumination units in the endoscope 3 shown in FIG. 3A , for example, two white LEDs are used. 39e, 39f, for routine observations in the visible region.

[0254] In addition, the endoscope 3B of the present embodiment is provided with, for example, an actuator for vibration in which a piezoelectric element is formed in an annular shape on the outer peripheral surface (or the inner peripheral surface) of the distal end portion of the capsule portion 22 ( The vibration unit) 131A, the vibration ac...

Embodiment 3

[0273] Next, Embodiment 3 of the present invention will be described with reference to FIGS. 23A to 24 .

[0274] 23A and 23B show an endoscope 3C according to Example 3 of the present invention. In this endoscope 3C, in the endoscope 3 shown in FIG. 3A , the rear end side of the outer casing 31 of the capsule portion 22 is also formed of a transparent member, and the base member 140 is disposed inside the rear end portion.

[0275] On the backside of the base member 140, for example, a white LED 141 for backlighting, and an objective lens 38B and a CCD 38B for imaging under the light of the white LED 142 are attached to form a backlighting and imaging unit 40B. This CCD 38B is also a CCD provided with a function that can change the gain in the CCD element.

[0276]In this way, in this embodiment, a rear lighting and imaging unit 40 for illuminating and imaging the front side (inside the body cavity) of the capsule unit 22 is provided on the front end side of the capsule unit...

Abstract

A container body includes an illumination section and an image pickup section. A tube body is integrally provided to the container body. A distal end of a hollow duct line provided in the tube body penetrates the container body to have an opening on an outer surface of the container body.

Description

technical field [0001] The present invention relates to an endoscope for endoscopic examination of the inside of a body cavity or the like. Background technique [0002] In recent years, endoscopes have been widely used in medical and industrial fields. Furthermore, recently, a capsule-shaped endoscope in a capsule shape has been proposed, and by swallowing it through the mouth or the like, it is possible to relatively easily perform endoscopic inspection in the body. [0003] In conventional capsule endoscopes, there is a disadvantage that after being inserted into the body cavity, the observation (photographing) window has a reduced imaging function due to adhesion of body fluids, etc. The state of the affected part in the state that should be treated is observed, and treatment, etc. cannot be performed. [0004] Furthermore, Japanese Patent Application Laid-Open No. 2003-135388 discloses a capsule endoscope for the purpose of staying in the body. [0005] In the previo...
