The rigid laparoscope is mainly composed of a rigid optical endoscope and accessories. The endoscope is mainly composed of lens, fiber , eyepiece, medical stainless steel and optical system. Its optical system is composed of objective lens, prism lens and several groups of image transmission lenses. The basic working principle is: the tissue observed in the laparoscope is imaged on the retina of the operator through the optical system, or a clear and enlarged image is displayed on the monitor after passing through the CCD interface.

The operator can inspect and diagnose the diseased tissue through the lesion images provided by the display screen of their eyepieces or their camera system.

In the clear view of the rigid laparoscope, the laparoscopic instruments can be used to further perform surgery on the local placement of the patient.
