The utility model discloses still can play fixed effect to camera and LED light source, avoid camera or light source to produce the slope, guarantee that the camera can shoot complete clear picture, and the LED light source can provide sufficient light for the camera.

2. The transparent cover is made of one of PC, PMMA and glass, and has enough transparency. The LED light source can penetrate through the transparent cover, and then the light of the LED light source can irradiate the human body part at the determined position. The human body part irradiated by the LED light source can reflect light to the camera, and the camera can shoot clear pictures. The translucent cover can not block light, then under the circumstances of guaranteeing that camera and LED light source are not polluted or are blockked up, the utility model discloses can guarantee that the light of camera is not influenced.

3. The interval on translucent cover surface and camera surface is 0.2 ~ 0.5mm, and then the thickness of camera department translucent cover is less, and light can pass the translucent cover very easily, guarantees that the camera can accurately shoot human corresponding part. The transparent cover can avoid the surface of camera to be sheltered from or block up, can not influence the light when the camera is shot again, guarantees that the camera can shoot clear picture.

4. The transparent cover keeps away from the interval between the face of pipe main part and the terminal surface of camera and is 0.3mm, and at this moment, the transparent cover part that the camera goes out has the best luminousness, guarantees that the camera can shoot enough clear pictures. The transparent cover that 0.3mm is thick is enough to carry out even cover to the surface of camera, guarantees that the camera surface is not polluted or is blockked up, guarantees that the camera normally works.

5. The instrument channel can be used for passing of instruments, and the instrument can conveniently obtain human tissues of the target position through the instrument channel. After setting up the apparatus passageway, the utility model discloses not only can remove the pipe main part and confirm the position and observe this position, can also conveniently acquire this position tissue, convenient operation. One end of the instrument channel tube extends out of the transparent cover, so that the transparent cover cannot block the instrument channel, and the instrument can conveniently extend out of the instrument channel.

6. The surface of translucent cover is the plane, and other objects are difficult for adhering to on the translucent cover surface, guarantee that camera and LED light source surface do not have the sheltering from all the time. Human tissue or liquid can not stop on curved translucent cover surface, further reduces the blockking in camera and LED light source the place ahead, guarantees that the camera can shoot more clear picture. The planar transparent cover avoids irregular refraction of light and ensures that more light irradiates the front.

7. The translucent cover surface coating glue coating, then the light transmissivity on translucent cover surface further improves, and then the light that the LED light source sent can see through the translucent cover, and light also can reach the camera more easily to the picture that the camera was shot is more clear, has compensatied the influence that translucent cover blocks that some light brought.

And 8, the LED light sources are respectively arranged beside the cameras, and the cameras can obtain enough light rays to ensure the definition of pictures shot by the cameras. Human tissue reflects sufficient light to the camera in, the picture luminance that then the camera was shot is enough, makes things convenient for medical personnel to shoot the picture according to the camera and carries out the analysis to pathological change.
