Endoscope mainframe and endoscope signal processing method

The present invention relates to an endoscope mainframe, and more particularly to an endoscope mainframe having signal determination and processing functions.

Endoscopes play an important role in medicine or industry. Take medicine as an example. Endoscopy can achieve the purpose of observing the internal organs of the human body with minimal damage, and penetrate deep into the human body through endoscopes, such as gastroscopes and bladders. Mirrors, etc., in order to capture images in the human body, in addition, can also cut tissue samples to provide biopsy, so it is of great significance for minimally invasive surgery. In the industry, endoscopes can be used for inspection and observation of high temperature, toxic, nuclear radiation and places that are invisible to the human eye. They are mainly used in automobiles, aero engines, pipelines, mechanical parts, etc., without disassembly or destruction. Non-destructive testing is achieved with assembly and equipment outage.

Common endoscopes include hard optical endoscopes, wrap-around fiber optic endoscopes, and digital imaged endoscopes. The hard optical endoscopes are equipped with a number of achromatic optics to form an image transmission system. High quality images, easy to use and cheaper than comparable quality fiber optic endoscopes are advantages. The wrap-around fiber optic endoscope can deeply inspect the hard-to-reach end of the hard-optic endoscope. It uses a soft optical fiber to form an image transmission system. Therefore, the torsion or bending of the endoscope axis does not affect the image transmission, but its image resolution. Depending on the number of fibers, the smaller the diameter of the fiber, the higher the imaging resolution, and of course the manufacturing cost increases. Digital imaging industrial endoscopes are directly imaged by CCD or CMOS wafers at the end of the endoscope, transmitted by signal transmission lines and processed by signal conversion processing circuits, and then provided to the monitor for display in standard image format. It is not directly visible when it is converted into an electrical signal. The advantage is that it can be observed by the screen. The disadvantage is that it is limited by the poor environmental resistance, and the temperature and shock resistance are not as good as those of the optical endoscope. It cannot be used in various occasions.

Hard optical endoscopes and wrap-around fiber optic endoscopes are optical endoscopes that transmit optical signals with optical signals and use eyepieces for visual observation. Digital imaged endoscopes transmit optical signals to screens with electrical signals. Watch. Hard optical and wrap-around fiber optic endoscopes can be connected to the CCD adapter, digital camera adapter or other conversion device on the eyepiece side. Perform video recording and filming for record analysis. But no matter what kind of conversion device, the back-end sensor can't be processed in a small area, so that a device about the size of the palm is needed to receive the signal, and if the eyepiece is removed and then transferred, in medical use. There is an increased risk of infection due to medical behavior, and other devices and devices are connected to the signal processing. The complicated process may cause inconvenience in use.

Both optical endoscopes and digital image endoscopes have their advantages and disadvantages, but there are still no products that can be applied to endoscopes of different signal types at the same time. In view of this, the inventors have been engaged in the manufacture and development of related products for many years.
