Obstetrical cervical dilatation device

Abstract

The invention relates to the technical field of medical instruments, and discloses an obstetrical cervical dilatation device. The device comprises an outer sleeve, wherein the outer sleeve is of a hollow cylindrical structure with an opening in the right end, the outer side wall of the outer sleeve is sleeved with a dilatation bag, a movable metal ring and a fixed metal ring are fixed to the center of the left side and the center of the right side of the dilatation bag correspondingly, the inner side wall of the movable metal ring is attached to the outer side wall of the outer sleeve, the inner side wall of the fixed metal ring is fixedly connected with the outer side wall of the outer sleeve, a magnetic block is connected into the outer sleeve in a sliding mode, and the magnetic block isin correspondence with the movable metal ring. When the cervical dilatation device is in use, the device is firstly placed at the cervix of a patient, then a medical worker pulls a connecting rod outwards to drive the magnetic block to move outwards, then the movable metal ring can be driven to move outwards, under the condition that the movable metal ring moves and the fixed metal ring does notmove, the dilating bag can be extruded and dilated, and thus, the cervix of the patient can be opened.
