A balloon uterine stent as shown in fig. 1 to 3, which comprises a catheter 4 and a balloon 1 extending from the end of the catheter 4. The saccule 1 can be heart-shaped, inverted pear-shaped, conical or other shapes with a wider upper end and a narrower lower end, and the shape with the wider upper end and the narrower lower end is beneficial to the attachment of endometrium. The portion of the balloon 1 that widens out at the lower end is designated in the present application as an ear 11 of the balloon 1.

The catheter 4 has through holes therein for water injection, and the outlet end 41 of the catheter 4 allows the internal fluid to flow to the surface of the balloon 1.

Ears 11 of balloon 1 may be used to curl from both sides to the middle, and because catheter 4 at the junction of balloon 1 and the catheter has some strength, the curled balloon has a cylindrical cavity in the middle, opposite to the outlet end 41 of the catheter. When fluid is flowing within the catheter 4, it can pass through the lumen of the crimped balloon 1.

The curled sacculus is hooped by the lantern ring, the lantern ring has certain elasticity, so that before pushing, the lantern ring limits the sacculus 1 to have a smaller retracted volume, after water injection, fluid flows out from the outlet end through the catheter and causes outward expansion pressure to the curled sacculus 1, the balloon 1 is extruded and expanded outwards, and when the pressure to the sacculus 1 is larger than the elastic force of the lantern ring, the sacculus 1 expands outwards, and after being pulled off the lantern ring, the lantern ring is unfolded, so that a state with a larger area is formed.

In a variant, one ear of the balloon 1 is fixedly connected to a portion of the first collar 2, and the first collar 2 can be stretched after crimping the balloon 1 so that the crimped balloon 1 is nested within the first collar 2. And after water injection the balloon 1 is detached from the first collar 2. But the detached first collar can still be connected with the balloon without falling off. To prevent the collar from remaining in the uterus and being difficult to remove.

In another variant, the other ear of the balloon 1 is fixedly connected to a second collar 3, the second collar 3 being able to cooperate with the push rod 4. The tail end of the auxiliary push rod 4 is attached to the balloon 1, so that the balloon 1 is pushed.

The balloon uterine stent of the present application further comprises a push rod 5. The pushing rod 5 is a rod-shaped piece with certain hardness and rigidity and is used for pushing the attached balloon 1 into the uterus. The push rod 5 is provided with a buckle 51, and the buckle 51 can be clamped on the outer wall of the conduit. The second collar 3 can be fitted over the push rod 5 at an initial stage and the balloon is driven to curl inwards by rotating the push rod and after curling is fitted through the first collar 2. After the water injection, the inflation of the balloon will cause the first collar 2 to slide off, the balloon to inflate and the second collar 3 to slide off the push rod 5.

A method of pushing a uterine balloon, comprising:

pushing the sacculus into the uterus by a pushing rod;

injecting water through the catheter to enable the balloon to be separated from the lantern ring and then expand;

and after water is injected, retracting the push rod.

The application process is as follows:

in the initial state of the balloon, the ear parts 11 at both sides of the balloon 1 are curled inwards to form a stick shape, a cavity is formed in the middle, and the curled balloon 1 is sleeved by the lantern ring at one side. The push rod 5 extends into the cavity. The buckle 51 of the push rod 5 is clamped on the outer wall of the guide pipe.

The balloon 1 is then pushed into the uterus with the push rod 5, and the balloon can be easily placed into the uterus due to the hardness and rigidity of the push rod 5.

And finally, injecting water into the catheter 4, wherein the water flows out from the catheter outlet end 41 and expands the balloon 1, and the far end of the balloon lantern ring is curled, so that the deformation is greater than that of the near lantern ring end of the balloon, the lantern ring can be broken away from the far lantern ring end of the balloon, and the balloon 1 is restored to the expanded shape.

This application is moulded the sacculus temporarily through the lantern ring on the sacculus 1 and is formed the rod type in order to make things convenient for through narrow and small cervical canal, through the back can resume former shape through the water injection operation. The operation of the surgical forceps is avoided, and the risks of contamination, balloon rupture and uterine perforation caused by the operation are also avoided. Meanwhile, as the initial state is a stick shape, compared with the manual crimping of the saccule by an operator, the saccule can be crimped into a smaller diameter, so the saccule can be placed without over-expanding the cervical orifice, and the injury to a patient is reduced.
