CN-122028838-A - Endoscope with a lens

Abstract

The solid state camera and the illumination emitter of the endoscope are mounted on opposite sides of the flexible circuit board. The flexible circuit board is mounted at the distal end of the insertion rod by engaging into a slot on the base. The base is formed as two sub-parts designed to cooperate together 5. The slot is formed into two opposing sub-slots, each sub-slot being formed in two sub-components. The subslot is designed to retain the flexible circuit board during assembly and to bend the flexible circuit board into a desired shape when the two base sub-components are brought together. The camera is pushed to a desired position by the elasticity of the flexible circuit board bent by the slot. The flexible circuit board has a retaining clip at its distal end. The retention clip grips to hold the 0 camera and the illumination emitter in a desired relationship within the distal end of the insertion rod.
