The endoscope is a detection instrument integrating traditional optics, ergonomics, precision machinery, modern electronics, mathematics and software into a whole. One has an image sensor, optical lens, light source illumination, mechanical device, etc. that can enter the stomach orally or through other natural orifices. Since a lesion which cannot be displayed by X-ray can be seen by an endoscope, it is very useful for a doctor. For example, with the aid of an endoscopist, an ulcer or tumor in the stomach can be observed, and an optimal treatment plan can be developed accordingly.

During the manufacture of the endoscope, the LED lamp and the CCD are usually fixed at the end part of a pipeline of the endoscope in a gluing or welding mode, and after the endoscope is designed in such a mode, in the process that the endoscope extends into a human body, the LED lamp and the CCD are easy to be subjected to resistance, so that the relative positions of the LED lamp and the CCD are changed, and the light source provided by the LED lamp received by the CCD is not uniform; meanwhile, in the transportation or taking process, the relative position of the LED lamp and the CCD may also change due to other reasons, for example, the package of the endoscope is squeezed or shaken in the transportation process.

Detailed Description

Example 1

As shown in fig. 1-2, an endoscope tip comprises a tip body 1, wherein the tip body 1 is transparent, an instrument channel 2 and a CCD channel 3 are coaxially arranged on the tip body 1 in a penetrating manner, a central axis of the instrument channel 2 is parallel to a central axis of the CCD channel 3, and light source placing cavities 4 are further arranged on two sides of the CCD channel 3 on the tip body 1.

In this embodiment, when in use, the tip body 1 is mounted on an end surface of a tube of an endoscope, and at the same time, a light source device of the endoscope is located in the light source placing cavity 4, and the CCD is aligned with the CCD channel 3 and located in the CCD channel 3, so that after the mounting, since the relative position between the light source (usually an LED lamp) and the CCD is determined by the design of the tip body 1 itself, after the design, the CCD channel 3 fixes the position of the CCD, and the light source placing cavity 4 fixes the position of the light source, the problem of the change of the relative position between the CCD and the light source during the process of carrying and taking the endoscope does not occur.

Example 2

In order to make end body 1 install on the pipeline of endoscope easily, place chamber 4 with the light source and set up to the axis the parallel blind hole of axis of apparatus passageway 2, after the design like this, when the endoscope used the LED lamp as the light source, the LED lamp can enter into the light source through the opening of blind hole and place the chamber 4 in, and the setting of the interior bottom surface of blind hole can prevent to stretch into human in-process at the endoscope, internal body fluid of human contacts with the LED lamp, and simultaneously, chamber 4 is placed to the source and sets up to the blind hole, conveniently when selecting phosphor powder as the light source, can hold phosphor powder and LED chip, prevent phosphor powder and human direct contact.

When the LED lamp is generally used for providing a light source for the endoscope, the cross section of the common LED lamp is rectangular, so that the cross section of the light source placing cavity 4 is designed to be rectangular, the light source placing cavity 4 can be perfectly matched with the LED lamp through the design, and the LED lamp is stable.

In order to better connect the tip body 1 to the conduit of the endoscope, a hollow conduit connecting part 6 is arranged at one end of the tip body 1, which is opened towards the light source placing cavity 4, and the conduit connecting part 6 is arranged coaxially with the instrument channel 2, so that after the design, a doctor can insert the instrument through the conduit of the endoscope and the conduit connecting part 6 to perform operations such as perfusion.

When a doctor inserts an instrument into a human body through a pipeline of an endoscope (not shown in a pipeline diagram of the endoscope), the top end of the instrument passes through the pipeline of the endoscope, the pipeline connecting part 6 and the instrument channel 2 in sequence; as the pipe of the endoscope is thin, the top end of the instrument is easy to touch the inner surfaces of the pipe connecting part 6 and the instrument channel 2 in the process of passing through the pipe connecting part 6 and the instrument channel 2, so that the inner surface of the pipe connecting part 6 is smoothly connected with the inner surface of the instrument channel 2, and the instrument is prevented from being clamped when the joint of the pipe connecting part 6 and the instrument channel 2 touches the pipe connecting part 6 or the inner surface of the instrument channel 2. In order to facilitate the doctor to extend the instrument into the human body through the instrument channel 2, the cross section of the instrument channel 2 is circular, because besides the circular shape, other shapes can generate angles, so that the instrument channel 2 is easy to clamp the instrument, and similarly, the cross section of the pipeline connecting part 6 is also designed to be circular, and the cross section of the tip body 1 is also preferably designed to be circular in order to be matched with the pipeline of the endoscope.

In order to be fitted with a conventional endoscope, the cross sections of the CCD channel 3 and the light source placing cavity 4 are aligned in a row on the tip body 1, and the instrument channel 2 is located in the middle of one side of the row (as shown in fig. 2).
