Vaginal constriction dilator

Abstract

The invention discloses a vaginal constriction dilator in the technical field of medical instruments. A bearing plate is arranged, the distance between a movable rod and the bearing plate is changed by moving the movable rod on the bearing plate, dilation pieces are arranged on a fixed rod and the movable rod, the distance between the two dilation pieces is adjustable, and therefore medical staff can adjust the position of the movable rod according to the size of the required operation area; an adjusting rod assembly is arranged between the fixed rod and the movable rod and used for adjusting the position of the movable rod on the bearing plate, an operating rod is pulled to drive a first connecting rod and a second connecting rod to rotate with a hinge column as the axis, the second connecting rod rotates and drives the movable rod to move at the same time, adjustment is carried out on the distance between the two dilation pieces, and therefore adjustment of the exposed area of the surgical area is achieved; and according to the dilator provided by the invention, a pudendum is dilated in an H shape, and compared with an X-shaped drag hook, the operation visual field is good, no obstacle obstructs the operation visual line, and the adjustment operation is convenient.
