Abstract
An inspection instrument for accessing a target area has a shaft with a structural core of flexible material. The core has sufficient rigidity to provide a continuous frame for the shaft, but also allows the shaft to be flexible for deflection. The core has a conduit means which passes through the core along a non-straight path to act as a deflection compensation means for conduit means deformation during shaft bending or deflection.
