The endoscope is a test instrument that integrates traditional optics, ergonomics, precision machinery, modern electronics, mathematics, and software. One has an image sensor, optical lens, light source illumination, mechanical device, etc., which can enter the stomach through the oral cavity or enter the body through other natural channels. The endoscope can be used to see lesions that X-rays cannot display, so it is very useful for doctors. For example, an endoscopic doctor can observe ulcers or tumors in the stomach and develop an optimal treatment plan accordingly.
Endoscopic surgery (endoscopy)
According to the technique of inspecting and treating the endoscope intuitively, it can be divided into non-invasive and traumatic. The former refers to the direct insertion of the endoscope, used to check the channel that communicates with the outside world (such as the digestive tract, respiratory tract, urinary tract, etc.) ; the latter is sent through the incision into the endoscope to check the closed body cavity (such as the chest cavity, Abdominal cavity, joint cavity, etc.).
The electronic camera uses microelectronic technology to photography and imaging. Its shape is the same as that of fiber-optic endoscope. By connecting the endoscope's eyepieces to the micro-camera connector, the image can be displayed on TV screen for observation, and the effect is similar to that of electronic endoscope. Endoscopes are divided into digestive tract, genitourinary tract, respiratory tract, body cavity and head organ speculum by purposes.
