In particular, the structure of the dilator in this embodiment, as shown in fig. 1 to 4 in particular, includes a dilator body b1, the dilator body b1 includes a handle b2 and a first dilation plate b3 and a second dilation plate b4 which can be controlled to be opened and closed by the handle b2, the first dilation plate b3 is hinged to the second dilation plate b4, and the first dilation plate b3 and the second dilation plate b4 are both duckbill upper beak-shaped structures. As shown in fig. 3 and 5, two symmetrical and vertical fixing rods b5 are fixedly connected to the inner bottom of the side where the first expansion plate b3 and the second expansion plate b4 are close to each other, two elastic silicone pieces b6 are respectively wound on the two fixing rods b5 located in the first expansion plate b3, and the side, away from the first expansion plate b3, of the two elastic silicone pieces b6 is respectively and fixedly connected to the surfaces of the two fixing rods b5 located in the second expansion plate b 4. Two elastic silicone pieces b6 are respectively abutted against two side gaps formed by the first expansion plate b3 and the second expansion plate b4 facing each other to completely or partially close the gaps. The elastic silicone sheet b6 of this embodiment is preferably made of a material with sufficient elasticity and a small thickness, so that when the vagina is opened, the elastic silicone sheet b6 can extend sufficiently to prevent the vaginal wall and cervical tissue in a relaxed state after delivery from entering the gap (slit) between the first expansion plate b3 and the second expansion plate b4, and to prevent pinching injury, therefore, it is preferable to design the elastic silicone sheet b6 to completely close the respective corresponding two side slits, and the vagina thus opened can facilitate the medical staff to fully examine the parturient after delivery. When the structure is used, the two expansion plates are opened by the handle and then released to be folded, the two expansion plates are quickly reset and folded under the action of the elastic silicone piece b6, and therefore, the elastic silicone piece b6 also plays a role in resetting.

Further, the dilator of the present embodiment may be embodied in the following structure:

as another embodiment, as shown in fig. 1 to 4, a pulling member for pulling the elastic silicone sheet b6 to be wound on its surface is provided on the fixing rod b5 located in the first expanding plate b3, that is, an iron ruler strip is wound on its body like a tape measure, this structure can make the elastic silicone sheet have no large elasticity, even made of an environment-friendly skin-friendly material having no elasticity, and is especially suitable for an examination occasion requiring a large degree of expansion of vagina. When the device is used, the closed first expansion board b3 and the closed second expansion board b4 are firstly extended into the vagina, the first expansion plate b3 and the second expansion plate b4 are expanded by the action of the handle b2 to expand the vagina, when the first expansion plate b3 and the second expansion plate b4 are expanded, the fixing rod b5 in the second expansion plate b4 pulls the elastic silicone pieces b6 to expand, so that the two elastic silicone pieces b6 can respectively cover the two side gaps between the first expansion plate b3 and the second expansion plate b4, so as to prevent the vaginal wall and the cervical tissue which are in a relaxed state after delivery from entering the gap between the first expansion plate b3 and the second expansion plate b4 and prevent clamping injury, therefore, the elastic silicone sheet b6 is preferably designed to completely close the gaps (gaps) on the two sides, so as to open the vagina, which is convenient for medical staff to examine the puerpera after delivery. When the first expansion plate b3 and the second expansion plate b4 are closed, the elastic silicone sheet b6 can be recovered to be wound on the surface of the fixing rod b5 under the action of the pulling piece, and the elastic silicone sheet is wound. When the first expansion plate b3 and the second expansion plate b4 are expanded, the elastic silicone sheet b6 can adaptively follow the angle change of the included angle between the first expansion plate b3 and the second expansion plate b4 to generate certain deformation under the left and right of the pulling piece, so as to close the gap between the first expansion plate b3 and the second expansion plate b4 as much as possible.

Specifically, referring to fig. 3, the pulling member is a spiral spring, the spiral spring is wound on the surface of the fixing rod b5 located in the first expansion plate b3, one end of the spiral spring is fixedly connected to the surface of the fixing rod b5, the other end of the spiral spring is fixedly connected to one side of the elastic silicone sheet b6, when the first expansion plate b3 and the second expansion plate b4 are opened, the spiral spring is stretched and tightened, and in the process of closing the first expansion plate b3 and the second expansion plate b4, the spiral spring pulls the elastic silicone sheet b6 to be wound on the surface of the fixing rod b5 in the first expansion plate b3 through the elastic action of the spiral spring, so that the design is more reasonable in use.
