The invention discloses a gastroscope device with a medicine atomizing function for the gastroenterology department. The gastroscope device structurally comprises an atomizing cavity, a medicine outlet spraying pipe, a medicine bottle, a liquid medicine sucking cavity, a liquid medicine atomizing cavity, a mist spraying cavity and a stomach inspection device. A stomach inspection device is provided with a stomach inspection eyepiece, an electronic connecting wire, an electronic adjusting device, a stomach inspection pipe, a gastropore penetrating pipe and an atomizing and inspection integratedlens. When the gastroscope device is used, rapid medicine changing can be conducted through a medicine bottle connector, rapid medicine guiding can be achieved through a liquid medicine sucking pump,rapid atomizing is realized through an electric heating wire and a bottom stirring paddle, rapid medicine applying can be conducted through the rapid atomizing effect, the atomized medicine applyingcan also be conducted under the influences of the minimum sensing, and the discomfort of a patient during medicine applying is reduced; meanwhile, the gastroscope device is small in size, simple in structure and rapid in medicine applying, and medical staff can suit the remedy to the case after checking out the pathogenesis.
