1. A surgical tool for use in a tissue removal procedure from a subject, the surgical tool comprising:
an elongated body comprising proximal and distal regions; and one or more flat tissue characterization assemblies, wherein each of said one or more flat tissue characterization assemblies comprises:
a flat sensor unit located at the distal region of said elongated body, comprising a sensing surface by which the flat sensor unit faces a region of interest, and one or more flat sensors each being configured for sensing one or more predetermined conditions, and each comprising a sensing region located in said sensing surface; anda single flat and thin signal transmission structure, extending between the proximal region of said elongated body and said sensing surface of said flat sensor unit and being electrically connected with said flat sensor unit, said single flat and thin signal transmission structure comprising one or more signal connection lines each associated with a respective one of said one or more flat sensors, whereinsaid single flat and thin signal transmission structure and said flat sensor unit are integrally coupled in a co-planar configuration forming a flat and thin integral structure, such that said single flat and thin signal transmission structure and said flat sensor unit have in common at least one continuous surface that is parallel, at the distal region of said elongated body, to the sensing surface of said flat sensor unit, said flat and thin integral structure thereby enabling impedance controlled signal transmission between said sensing surface of said flat sensor unit and said proximal region of said elongated body. |
