Optical Fiber Soft Mirror

Optical fiber soft mirror is divided into three kinds, single channel fiber soft mirror, double channel fiber soft mirror and combined fiber soft mirror

① Single channel fiber soft mirror

Single channel fiber ureteroscope is the most widely used ureteroscope

The basic principle of optical fiber soft mirror is: the light emitted by an external light source is transmitted to a concave lens at the tip of the endoscope (the farthest part of the soft mirror) through the guiding optical fiber bundle, and the concave lens is radiated to obtain a wider lighting field of view. After the internal organs are irradiated by light, the reflected light from the interface of the organs and tissues enters the imaging channel at the tip of the soft mirror. The objective lens is imaged on the end face of the image conduction fiber bundle, and then transmitted to the end of the eyepiece through the image conduction fiber bundle. The surgeon can see a clear internal image from the eyepiece, and the eyepiece can be connected to the camera system to display the internal image through the television. After clearly observing the situation in the body, the surgeon can insert laser fiber, stone basket, biopsy forceps and other instruments through the operation channel of the soft mirror for corresponding surgical operations.
