Embodiment Construction
[0011] Such as figure 1 as shown in figure 1 As shown, a novel cavity direct imaging device includes a sheath body 1 that can be inserted into the cavity, an illumination system and a camera system. The illumination system is an LED lamp 2, and the LED lamp is connected to an external power supply through a power cord 3. The camera system includes a camera 4. Image processing system and image display, the camera 4 is connected to the image processing system through the signal line 5, the LED light 2 and the camera 4 are fixed as a whole, arranged side by side at the front end of the sheath body 1 extending into the cavity, the power line 3 and the signal line 5 are all arranged in the sheath.

The invention relates to a cavity direct image collecting device, comprising a sheath body that can be inserted into the cavity, a lighting system and a camera system, which is characterized in that: the camera system comprises a camera, an image processing system and an image display; the camera is directly arranged on the front end of the sheath body inserted into the cavity, and is connected with the image processing system through signal wires. Since the camera is directly arranged on the front end of the sheath body inserted into the cavity, the camera is directly led into the cavity along with the sheath body during use, and optical fiber is not needed for transmitting to the external for connecting with the camera through lens, making the image more distinct; besides, since optical fiber is not needed, the service life of the cavity direct image collecting device is prolonged.
Description
technical field [0001] The patent of the present invention relates to a medical device, in particular to a cavity direct imaging device. Background technique [0002] The medical cavity direct imaging device is a device used to observe cavity pathological changes in the diagnosis or operation of human cavity diseases, and its image quality is directly related to the effect of diagnosis and treatment. The existing cavity direct imaging device includes an illumination system, a camera, an image processing system, and an image display mechanism. The illumination system mostly uses a cold light source conducted by an optical fiber, that is, the light source is transmitted to the cavity of the human body through an optical fiber, and the image of the cavity is also transmitted through an optical fiber. It is transmitted outside the body, and then connected to the camera through the lens, resulting in a decrease in image clarity. Moreover, the optical fiber is not only expensive,...
