FIELD: medicine. ^ SUBSTANCE: device contains an endoscope with sensors of tissue density, installed on endoscope butt end and a computer made with possibility to register pressure of sublying tissue section density and resistance to pressure from each sensor. Sensors of tissue density are made in form of matrix if replaceable measuring modules installed on bearing plate, each module consisting of case in whose through hole with possibility of travel under action of spring installed is rod provided on the end, protruding from case hole, with replaceable tip, opposite side of through hole is blocked with lid with fixed on it sensor for measuring rod travel, connected to signal amplifier. Outlets of all amplifiers are connected with inlet of adder of applied forces, whose outlet is connected to inlet of element indicating applied forces, outlet of each signal amplifier is also connected with first inlets of corresponding units of upper and lower rod position control, to whose second inlets connected are sources of reference voltage of rod upper and lower limiting positions, outlets of units of control of rod upper limiting position of all measuring modules are connected with inlets of "OR" element of rod upper limiting position, outlets of units of control of rod lower limiting position of all measuring modules are connected with inlets of "OR" element of rod lower limiting position, outlets of both "OR" elements are connected to elements indicating rod upper and lower limiting positions. Signal amplifiers, adder and "OR" elements of rod upper and lower limiting positions are connected to controller of port of parallel computer input-output. ^ EFFECT: application of invention allows to extend possibilities of examining sublying tissue in order to determine its homogeneity and density. ^ 3 dwg, 3 cl |
