Furthermore, the grooves are in a group and are all arranged on the outer edge of the expansion frame.

Furthermore, the openings at two ends of the top of the groove are designed into a round corner structure.

Further, the dilating frames are inclined in the direction of the operator.

Further, the platform protrudes in the direction of the patient.

Further, the inner edge of the expansion frame is designed to be a round corner structure.

Preferably, the dilating frames comprise a split ring structure or an annular structure.

Preferably, the dilating frames comprise a circular, elliptical or square ring structure.

The beneficial effects of the utility model are that can fully expose the cloudy formula operation field of vision, use manpower sparingly, simple structure, low cost, the easy flexible regulation elasticity drag hook position, and expansion frame can fix on the operation cloth with the double faced adhesive tape.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example one

As shown in fig. 1, 2, 3 and 4, the present embodiment provides a vaginal dilator for gynecology, which comprises a dilating frame 1 and two elastic draw hooks 2; the outer edge of the expanding frame 1 is provided with a groove 11 for the elastic drag hook 2 to be clamped.

One side of the expansion frame 1 is provided with a platform 13 for adhesion and fixation, and a double-sided adhesive tape is pasted on the platform 13.

The elastic drag hook 2 comprises a drag hook 21 and an elastic pull rope 22, the handle end of the drag hook 21 is fixedly connected with the elastic pull rope 22, and a section of the elastic pull rope 22 far away from the drag hook 21 is used for being clamped into the groove 11. As shown in fig. 1, the double-sided adhesive tape attached to the platform 13 is torn off during the operation, and the stent 1 is fixed by being attached to the surgical drape, thereby preventing the device from shaking and affecting the operation. Then the elastic draw hook 2 is hooked into the inner side of the labia minora or the vaginal wall, the opposite ends are stretched to draw the vaginal opening, and then the elastic draw rope 22 is clamped in the groove 11, so that the length and the tightness of the elastic draw hook 2 can be flexibly adjusted in a telescopic way.

The grooves 11 are in a group and are all arranged on the outer edge of the expansion frame 1. The groove 11 is used for clamping the elastic draw hook 2, and the elastic draw hook 2 is arranged on the outer edge of the expansion frame 1 and is directly clamped into the groove 11 downwards after being stretched forcibly on the expansion frame 1.

The top two ends of the groove 11 are open and designed to be round-cornered. The design of the top fillet of the groove 11 enables an operator to easily grope the opening of the groove 11 when clamping the elastic drag hook 2, and enables the elastic drag hook to be more easily clamped into the groove 11.

The dilating frames 1 are inclined in the direction of the operator. The expanding frame 1 of the design is in a horn shape with an opening facing an operator, the part of the expanding frame 1 contacted with the body of a patient is designed to accord with the anatomical structure of the private part of a human body, and the expanding frame 1 is convenient to cling to the private part after being bonded with the operation cloth through double-sided adhesive tape.

Platform 13 is protruding to patient's direction, makes platform 13 pass through the double faced adhesive tape and closes better with the operation cloth, more does benefit to the fixed of expansion frame 1.

The inner edge of the dilating frames 1 is designed as a rounded structure. The part of the dilating frames 1 contacting with the patient is designed into a round angle, so that the contact feeling of the patient can be more comfortable and more beautiful.

The dilating frames comprise open ring structures or annular structures. The present embodiment is an open ring structure.

The dilating frames comprise circular, elliptical or square ring structures. The present embodiment is a circular ring structure.

Example two:

as shown in fig. 5 and 6, the present embodiment is different from the first embodiment in that the dilating frames 1 of the present embodiment have a closed circular ring structure.

Example three:

as shown in fig. 7 and 8, the difference between the present embodiment and the first embodiment is that the dilating frames 1 of the present embodiment are open square ring structures.

Example four:

as shown in fig. 9 and 10, the present embodiment is different from the first embodiment in that the dilating frames 1 of the present embodiment are of a closed square ring structure.

Example five:

as shown in fig. 11 and 12, the present embodiment is different from the first embodiment in that the dilating frames 1 of the present embodiment are of an open elliptical ring structure.

Example six:

as shown in fig. 13 and 14, the present embodiment is different from the first embodiment in that the dilating frames 1 of the present embodiment are of a closed elliptical ring structure.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
