Classification of Endoscopes

　　Endoscope is a widely used technical tool in the medical and industrial fields, which can enter the human body or equipment through small-sized probes, providing convenience for observation, diagnosis, and maintenance. There are various types of endoscopes, which can be divided into two categories based on their application fields and functions: medical endoscopes and industrial endoscopes.

　　Medical endoscopes are mainly used for medical diagnosis and surgery. Common medical endoscopes include gastroscope, enteroscope, Cystoscopy, laryngoscope, etc. They can conduct real-time observation inside the human body through flexible probes and high-definition image sensors to detect and diagnose various diseases. The application of medical endoscope is very extensive, which can be used for the examination of gastrointestinal diseases, Cancer screening, diagnosis of organ diseases, guidance of surgical procedures, etc. The development of endoscopic technology also enables some traditional open surgery to be converted to Minimally invasive procedure, reducing the trauma and recovery time of patients.

　　In addition to medical endoscopes and industrial endoscopes, endoscopes can also be further subdivided according to different classification methods. The following are some common endoscopic classification methods:

　　Rigid endoscope and flexible endoscope: According to the rigidity of the probe, endoscopes can be divided into rigid endoscope and flexible endoscope. Rigid endoscopes are made of rigid materials and are suitable for direct observation into larger cavities and cavities. The flexible endoscope is composed of soft Optical fiber and curved conduit, which can enter into narrower and curved parts and has greater flexibility and operability.

　　Tube diameter size: The tube diameter size of an endoscope is also a common classification method. Different endoscopes are suitable for different applications. Usually, thinner pipe diameters are suitable for observing small cavities or organs, while larger pipe diameters are suitable for examining larger cavities or organs.

　　Function and application field: Endoscopes can also be classified based on their specific function and application field. For example, gastroscope is used to check the stomach and esophagus, Cystoscopy is used to check the bladder, and Arthroscopy is used for intra-articular observation and surgery.

　　Image sensor and light source type: The image sensor and light source technology in endoscopes are also one of the basis for classification. For example, traditional endoscopes use fiber optics to transmit light, while modern endoscopes typically use digital image sensors and LED light sources to provide higher quality images and light sources.

　　Scope of activity: Endoscopes can also be classified based on their scope of activity. For example, a whole body endoscope system can be used for whole body organ examination, while a local endoscope is suitable for observing and operating specific parts.

　　These classification methods are only a part of endoscopic classification, and with the continuous progress of technology and the continuous evolution of application requirements, more classification methods and new types of endoscopes may emerge. These classifications help to better select suitable tools and meet specific needs when using endoscopes in the medical and industrial fields.
