Endoscopy is widely used in clinical practice for the treatment of different departments and diseases. Mainly divided into flexible endoscopy (referred to as soft endoscopy) and rigid endoscopy (referred to as hard endoscopy), soft endoscopy mainly includes gastroscopy, colonoscopy, laryngoscopy, fiberoptic bronchoscopy, etc; Hard mirrors include laparoscopic thoracoscopy, ureteroscopy, cystoscopy, arthroscopy, hysteroscopy, etc.
Hard mirrors can be classified into categories such as laparoscopic thoracoscopy and hysteroscopy. Various types of hard lenses are used in combination with supporting equipment to complete the diagnosis and treatment of various types of diseases. The main supporting equipment for hard mirrors includes camera system hosts, cameras, cold light sources, monitors, trolleys, etc. Hard mirrors mainly enter sterile tissues and organs in the human body or enter sterile chambers through surgical incisions, such as laparoscopic thoracoscopy, arthroscopy, intervertebral disc endoscopy, and ventriculoscopy. The hard mirror is a prism optical system, with the greatest advantage of clear imaging, multiple working channels, and multiple viewing angles.
Soft endoscopy mainly completes examination, diagnosis, and treatment through the natural lumen of the human body, such as gastroscopy, colonoscopy, laryngoscopy, bronchoscopy, etc. It mainly enters the human body through the digestive tract, respiratory tract, and urinary tract. The optical system of the soft mirror is an optical fiber optic system. The biggest feature of this fiber optic endoscope is that the lens can be manipulated by the operator to change direction and expand the application range, but the imaging effect is not as good as that of the hard mirror. Soft endoscopy has been applied in multiple departments such as gastroenterology, respiratory medicine, otolaryngology, urology, anorectal surgery, thoracic surgery, gynecology, etc. From simple disease screening to the treatment of complex achalasia, it brings benefits such as timely and accurate diagnosis and treatment, low risk, minimal surgical trauma, and fast postoperative recovery to patients.
