The focusing device and the base are fixed and can not be detached, so that only the protective glass is required to be arranged on the focusing device, the protective glass on the base is removed, the imaging distance of the CCD module sensor is shortened, and the problem of short rear intercept of the focusing device and the CCD module is solved. The image content is richer, the color is more accurate, and the picture is more vivid.

Preferably, the base comprises a focusing base and a module base which are integrally formed, protective glass is installed at the end part of the focusing device, and the end part of the focusing device penetrates through the base to be connected with the CCD module. The focusing base and the module base are respectively used for fixing the focusing device and the module sensor, the fixed positions are distributed properly, all the parts can be well fixed on the base, and the base is fixed on the shell, so that all the parts are fixed on the shell.

Preferably, the end face of the module base is connected with the end face of the CCD module, and the CCD module is installed on the module base through module installation screws. The end part of the focusing device extends into the module base to be in threaded connection with the module base, and a radial focusing fixing screw is arranged at the joint of the focusing base and the focusing device. The base is fixed to the housing by base set screws at the interface of the module base and the housing. All through screw fixed connection, fixed knot constructs stably simply.

Preferably, the shell is provided with a button, a pressing plate is arranged above the button, a button control plate is arranged below the button, and the button is fixed on the shell through the pressing plate and the button control plate. The CCD module sensor adopts a 3 multiplied by 1/3 model 16: 9 full high-definition CMOS sensor. The resolution ratio of traditional endoscope camera system is generally below 768 x 576, the utility model discloses can make resolution ratio reach 1920 x 1080, the definition is high, makes things convenient for the doctor to diagnose, improves the degree of accuracy. The white balance of the camera is focused through the buttons, the image freezing function can be realized, and the playback and the amplification observation of a doctor are facilitated. The press plates are arranged on the upper portion and the lower portion of the button, and the press plates are located on the upper portion and the lower portion of the press plate, so that the button is fixed on the shell. The utility model discloses a camera device overall dimension is little, conveniently carries and installs.

Preferably, the focusing device comprises a focusing interface, a focusing rod is arranged outside the focusing interface, one end of the focusing interface is connected with an eye patch of the endoscope, and the other end of the focusing interface is connected with the CCD module.

Preferably, a sheath is sleeved outside the connecting joint. The sheath is used for supporting the cable, so that the cable can be smoothly led out from the shell to be connected with the endoscope image display system.

Therefore, the camera applied to the medical endoscope of the utility model has the following advantages: the imaging definition is improved by utilizing a high-definition CMOS sensor, so that a doctor can make diagnosis and treatment more accurately; an adjustable connecting device is arranged between an eyeshade of the endoscope and the camera system, so that focusing and focusing are facilitated, and image display is clearer.
