FIELD: medicine.
SUBSTANCE: invention relates to medical equipment, in particular to practice and technique of endoscopy of different human organs. Tactile display device for tissue density analysis contains endoscope with sensors of tissue density, with sensors of tissue density being pressure sensors, made in form of resilient chambers, filled with pressure-perceiving medium, for instance, physiological solution. Device additionally includes tactile display units, containing chambers of thermal actuator, bringing elements of tactile information display into motion, heating elements, coolers and connecting tubes. Device also additionally includes measuring amplifiers, units of comparison with support voltage, units of comparison with feedback, total pressure summer, units of negative value allocation, rectifiers, units of positive value allocation, units of cooler control, measuring amplifiers of sensors of thermal actuator pressure, source of support voltage, elements for indication of uniformity of endoscope pressure sensors tightness, element for indication of total pressure value.
EFFECT: invention will make it possible to extend functional possibilities of device and carry out tactile analysis of biological tissue density by endoscopic method with transmission of tactile information for doctor's hand perception on tactile display.
