The invention belongs to the field of medical appliances, and particularly discloses a vaginoscope system with an infrared thermal scanning function, which comprises a hard vaginoscope, a cold light source host machine, a camera host machine and an endoscope monitor, wherein the cold light source host machine, camera host machine and endoscope monitor are connected with the hard vaginoscope; the hard vaginoscope is also connected with an infrared thermal scanning system; and the infrared thermal scanning system comprises an infrared thermal scanning probe, an infrared thermal scanning processing system host machine and an infrared thermal scanning system monitor. On the basis of the traditional vaginoscope, the infrared thermal scanning technology is introduced to the vaginoscope system with an infrared thermal scanning function, and a stereoscopic vascular static image of the vaginal wall is clearly displayed by utilizing the linear and annular motions of the infrared thermal scanning probe, thereby providing reliable and objective references for the doctor to judge the pathological changes and functional state of the vagina. In addition, the infrared thermal scanning processing system provides multiple working modes, including common display mode and night display mode, so that the doctor can make a proper diagnosis by analyzing and comparing diagnostic images in different display modes. The invention greatly enriches the means for diagnosing the vaginal diseases and effectively enhances the diagnostic accuracy.
