Medical electronic endoscope is a common medical device that can perform inspection and treatment inside the human body. It mainly consists of light source, image sensor, control system and flexible probe. The probe end of the endoscope can also be equipped with some tiny tools for inspection or treatment.
The basic principle of medical electronic endoscopy is to use the light irradiated by the light source at the end of the probe to emit into the body and be reflected back, and after conversion by the image sensor, a high-definition image is formed. The image sensor can transmit the image to the display screen, the doctor can observe the image and make a diagnosis. The quality of the electronic endoscopic image mainly depends on the performance of the CCD, followed by the technical indicators of the drive circuit and post-processing system, including resolution, sensitivity, noise, spectral response, dark current, dynamic range, and image lag.
Clinical application: Medical electronic endoscopes are widely used in the examination and treatment of internal organs of the human body, including gastrointestinal tract, respiratory tract, genitourinary system and other aspects. For example, gastrointestinal electronic endoscopy can detect and treat gastrointestinal diseases, such as gastric cancer, gastric ulcer, colorectal cancer, etc.; respiratory electronic endoscopy can detect and treat lung cancer, tracheal stenosis and other diseases. Medical electronic endoscopes can also perform treatment operations such as excision and biopsy, which can reduce the pain of patients and improve the treatment effect.
