Haptic sensor system i.e. optical waveguide sensor system, for use in surgical instrument in e.g. medical region for display and registration of type and intensity of mechanical contacts, has display device displaying signal attenuation

摘要

The system i.e. haptic optical waveguide sensor system (5), has sensors designed as deformable optical waveguide loops (6-9) and differential coil. A contact mechanism (10) contacts with the optical waveguide loops and is designed in a movable manner with degree of freedom. The loops are hooked with an external electronics unit such that attenuation of an optical signal in the loops by deformation of the loops, is measured and evaluated, where the attenuation is audible or visible using a display device. The loops are hooked with a control device for haptic simulation on a handgrip.
