The invention belongs to the field of medical instruments and apparatuses, and discloses a confocal micro hard hysteroscope system comprising a hard hysterscope. The confocal micro hard hysteroscope system further comprises a confocal micro probe and a confocal micro probe system host machine; the hard hysteroscope system is at least provided with a straight line type channel for instruments and apparatuses; the confocal micro probe comprises a working end part and an interface; and the working end part of the confocal micro probe penetrates through the straight line type channel for instruments and apparatuses to combine the hard hysteroscope with the confocal micro probe. In the confocal micro hard hysteroscope system, the advanced confocal laser scanning microtechnology is introduced into the diagnosis of gynecologic operation; the lesions of uterine mucous membrane or cancerization and the like can be clearly observed by putting the confocal micro probe into an uterine cavity through the channel for instruments and apparatuses of the hard hysteroscope and amplifying the tissue by more than 500 times by the confocal micro probe under the combined action of fluorescein sodium; the recognition of the uterus and the lesions thereof is led to the microscopic world, thereby making positioning and qualitative diagnosis of living body cells; and the confocal micro hard electronic hysteroscope system provides a powerful tool for the recognition of the uterine mucous membrane and the lesions thereof, and provides reliable basis for the treatment and research.
