The invention belongs to the technical field of gynaecology and
obstetrics, and discloses a gynaecology and
obstetrics uterine curettage device which comprises a movable block, a guide rail is arranged below the movable block, first fixing seats are fixedly mounted on the left side and the right side of the bottom end of the movable block, supporting plates are arranged on the left side and the right side of a mounting rod, and a
liquid storage tank is fixedly mounted at the bottom end of the mounting rod. And the bottom end of the
liquid storage tank fixedly communicates with a limiting
pipe. According to the cervical
dilator, the
piston plate is driven to displace and compress the
alcohol while the supporting plate dilates the
vagina, the dilation device is directly pushed to displace by utilizing the pressure provided when the
alcohol is compressed, so that the dilation device is inserted into the
cervix uteri so as to perform subsequent
cervical dilation, and a power source and power during
vagina dilation are utilized, so that the
cervical dilation effect is greatly improved. The
vagina dilator is simple in structure and convenient to operate, secondary injury caused by step-by-step operation when a traditional device firstly dilates the vagina and then dilates the
cervix uteri is avoided, vagina dilation and
cervix uteri dilation are carried out at the same time, secondary injury is avoided, operation steps are simplified, and operation efficiency is improved.
