It is avoided that if the uterine cavity stent in the expanded state is directly folded and rolled up, and then clamped with a clip and placed in the uterine cavity, it will be difficult to operate due to its toughness, and it is easy to fall apart, which is time-consuming and laborious. The ring 15 set on the inner wall of the through hole 14 at the top of the catheter 1 is connected to the airbag stent 2, and the connecting head 3 is set at the bottom of the catheter 1, and the first branch tube 4 and the second branch tube 5 are respectively set on both sides of the lower end of the catheter 1. After the airbag stent 2 is deflated, it can shrink into a long strip, which is convenient for insertion into the uterine cavity. When it is inserted, it only needs to use an external inflation device to connect the inflation head 11, and the airbag stent 2 can be charged through the inner cavity of the second branch tube 5 and the inflation cavity 9. The inner cavity is filled with gas, so that the airbag support 2 can be unfolded into a triangle after gradually expanding, which can prevent uterine adhesion. The block 6 is arranged on the outer wall of the upper end of the catheter 1 and is located above the ring 15. The establishment of the block 6 can facilitate the gradual expansion of the airbag support 2. After the lower end drives the ring 15 to move upward, the block 6 can block the ring 15 to prevent the lower end of the airbag support 2 from excessively moving upward and blocking the drainage hole 12. The catheter 1 is provided with a drainage hole 12 and a medicine outlet hole 13, and the drainage hole 12 is located above the block 6 and is connected to the drainage cavity 7.

After the insertion is completed, it is only necessary to use an external inflation device to connect the inflation head 11, and gas can be filled into the inner cavity of the airbag support 2 through the inner cavity of the second branch tube 5 and the inflation cavity 9, so that the airbag support 2 can be expanded into a triangle after gradually expanding, thereby preventing uterine cavity adhesion. By setting up the stopper 6, it is convenient for the airbag support 2 to gradually expand, and its lower end drives the ring 15 to move upward, The block 6 can block the ring 15 to prevent the lower end of the airbag support 2 from moving upward excessively and blocking the drainage hole 12. By connecting the drainage device to the connector 3, the fluid in the uterine cavity can be drained through the drainage cavity 7 and the drainage hole 12 to reduce the probability of intrauterine infection. The one-way valve 19 in the drainage cavity 7 can be set up to prevent the liquid from flowing back. By connecting the syringe to the injection head 10, the liquid medicine can be injected into the patient's uterine cavity through the inner cavity of the first branch tube 4, the injection cavity 8 and the outlet hole 13.
