Abstract

The invention relates to an electronic digital endoscope. The electronic digital endoscope comprises an endoscope body, an annular illumination device, a handheld camera, a focusing device, an LED cold light source and an inflation device. The handheld camera is connected with the focusing device through a movable connecting structure, the focusing device is connected with the eyepiece end of the annular illumination device through a rapid connecting clamping ring, the illuminating end of the annular illumination device is connected with the endoscope body in a threaded mode, and the LED cold light source and the inflation device are connected with a light passing pipe of the annular illumination device and a ventilating pipe of the annular illumination device respectively. The annular illumination device is adopted, and therefore the lighting effect is good, no illumination dark points exist, and the illumination is uniform. The focusing device is rapidly connected with the annular illumination device through the rapid connecting clamping ring, operation is convenient, and locking is firm. The focusing device can be replaced by focusing devices with different focal lengths according to the different endoscope bodies and different use environments, and the endoscope is convenient and flexible to use.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an electronic digital endoscope. Background technique [0002] During the treatment of certain diseases, it is necessary to use an endoscope to observe the relevant organs in the patient's body, and take images of the relevant organs in the patient's body through the camera device, and at the same time transmit the images to the external visual device. Such as oral endoscope, ENT endoscope, dental endoscope or rectal endoscope, etc. In order to see a clear image in the body, it is necessary to illuminate the environment in the body. At present, point light sources are generally used for lighting, and the light efficiency is low, and the illumination is not strong enough. Not clear enough to affect the doctor's diagnosis of the patient's condition. In addition, for different endoscopes and use environments, it is often necessary to use focusing devices with different focal len...
