Detailed ways

The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings.

Example:

The disposable aseptic vaginal dilator shown in Figure 1 includes an upper expansion leaf 1, a lower expansion leaf 2 and a push rod 3, the lower expansion leaf 2 is provided with a push rod 3 assembly groove, and the two sides of the push rod 3 are processed with Assembling strips, sliding connection between the push rod 3 and the lower expansion leaf 2, rotational connection between the push rod 3 and the upper expansion leaf 1, the upper expansion leaf 1 is processed with a flue exhaust duct 11 for removing smoke in the cavity, the The outlet end of the exhaust duct 11 is provided with a card slot 12 for clamping the suction pipe, and the upper expansion leaf 1 and the lower expansion leaf 2 are both made of transparent PC material; the push rod 3 is made of matt ABS and PC The material is processed.

When the utility model is designed, it is considered to set up a smoke exhaust duct 11 on the inside or outside of the upper expansion leaf 1. During the doctor's treatment of the patient's focus, the smoke generated by the vaginal cavity will be collected in the exhaust duct 11, and the suction tube at the slot 12 Suck it out to ensure that the smoke in the vaginal cavity does not collect, and the doctor has a good vision for diagnosis.

In this embodiment, the exhaust duct 11 is preferably arranged on the inner side of the upper expansion leaf 1 , the exhaust duct 11 is arc-shaped, and the slot 12 is U-shaped. As mentioned above, the exhaust duct 11 can be arranged on the outside or inside, but when it is arranged on the inside, it can be realized without increasing the volume of the upper expansion leaf 1 or changing the external structure of the upper expansion leaf 1, and the patient's comfort level during use good.

Specifically, the upper expansion leaf 1 is integrally formed by the end, the expansion part and the assembly part, and the end part is bent inward. The lower expansion leaf 2 is integrally formed by the end, the expansion part and the operation part, and the end is bent inward. The ends of the upper and lower expansion leaves are relatively curved, the volume of the ends is reduced, the use is convenient, and the patient's comfort is good; the card slot 12 is composed of an introduction part and a clamping part, and the diameter of the introduction part is greater than or equal to the diameter of the clamping part , The diameter of the clamping part is equal to the diameter of the F30 suction tube used clinically.

The top of the push rod 3 is also fixedly processed with a positioning piece 4 for positioning the upper expansion leaf 1 during operation. The positioning piece 4 is an elastic piece provided with several teeth. After the dilator is opened at a certain angle, release the upper expansion leaf 1, and the upper expansion leaf 1 will be locked by the locking teeth and positioned. When it needs to be reset, press the upper expansion leaf 1 again, and after releasing the upper expansion leaf 1, the The upper and lower expansion leaves of the device are reset and closed.

In this embodiment, the positioning member 4 is preferably arranged in the middle of the top end of the push rod 3 . This design has good stability and can avoid misalignment between the upper and lower expansion leaves. The hand-held part of the push rod 3 is also processed with an anti-slip structure 5, so that the doctor has a good grip and good stability when operating.

In this embodiment, the rear end of the assembling part of the upper expansion leaf 1 is provided with a destroyable part 13 , that is, the destroyable part 13 and the upper expansion leaf 1 are integrally formed. After the dilator is used up, a larger external force is applied to the destructible part 13 to cause it to break, and the dilator is destroyed to avoid repeated use, and the safety is high.

The above-described embodiment is only a preferred solution of the utility model, and does not limit the utility model in any form. There are other variations and improvements without exceeding the technical solution described in the claims. type.
