technical field

The invention belongs to the field of medical instruments, in particular to a hysteroscope.

Background technique

Hysteroscope is clinically used to treat uterine cavity lesions. It is a common equipment for gynecological minimally invasive operations. There will often be some intracavitary tissue shedding or bleeding, because the volume of the uterine cavity is small, these will blur the lens of the hysteroscope, thus affecting the doctor's visual observation; and once the detached tissue is large, it cannot continue To perform a surgical operation, the hysteroscope must be taken out, the tissue removed, and then the second operation is performed; once such surgical work is repeated many times, the operation time is prolonged, which not only brings certain psychological pressure to the medical staff and patients, but also Because it increases the number of times the hysteroscope enters and exits the cervical canal during the operation, the risk of cervical injury and gas embolism increases.
