METHOD OF TRANSMISSION AND REPRESENTATION OF TACTILE INFORMATION IN ENDOSCOPIC EXAMINATION OF TISSUE DENSITY Russian patent published in 2010 - IPC A61B1/00 G01N29/00 G06T7/00 

FIELD: medicine.

SUBSTANCE: invention relates to medical equipment. Device contains endoscope with sensors of tissue density, which are sensors of endoscope pressure, made in form of elastic chambers filled with pressure-sustaining medium, and unit of processing and representation of information in dynamic mode, which includes display for representing tactile information, which consists of basis, in whose cells fixed are elements of tactile information reflection. Each of representation elements consists of hollow case, blocked in upper part with thin flexible film, and in lower part having inputs of tube for compressed air supply, connected via inlet valve with main of compressed air, tubes of air outlet, connected with atmosphere via outlet valve, and tube of sensor of representation element pressure. Outlets of endoscope pressure sensors via corresponding measuring amplifiers and amplifiers with regulated transmission coefficient are connected with first inlets of units of inlet valve control units and units of control of outlet valves, whose second inlets are connected with sensors of representation elements pressure, inlets of regulating coefficient of transmission of amplifiers with regulated coefficient of transmission are connected with master control of transmission coefficient, outlets of measuring amplifiers are connected with inlets of general pressure adder, whose outlet is switched to first inlets of units of upper and lower pressure comparison, second inlets of units of upper and lower pressure comparison are connected with master controls of upper and lower pressure respectively, and outlets of units of upper and lower pressure comparison are connected with upper and lower pressure indicators.

EFFECT: invention allows to transmit tactile information to display for perception with doctor's hand during tactile examination of biological tissue by endoscopic method.
