[0028] like Figure 2 As shown, a cylinder 6 is connected to the outer wall of the movable column 3, and a connecting rod 9 is slidably connected to the outer wall of the cylinder 6. The connecting rod 9 is used to drive the arc block 16 to move. A moving groove is opened at one end of the cylinder 6 to facilitate the sliding connection of the connecting rod 9. A first spring 8 is provided between the outer wall of the connecting rod 9 and the bottom of the moving groove. The first spring 8 is used to push the connecting rod 9. The top end of the connecting rod 9 is fixedly connected to the bottom end of the arc block 16.

[0029] like Figure 3 As shown, the outer wall of the first spring 8 is fixedly connected to two square blocks 15 that are distributed in a mirror image. The inner wall of the square block 15 is slidably connected to a moving rod 10. The inner wall of the moving rod 10 is slidably connected to a soft ball 11 that slides against the inner wall of the annular airbag 4. The moving rod 10 is used to drive the soft ball 11, and the soft ball 11 is used to support the interior of the annular airbag 4.

[0030] like Figure 4 As shown, a disc 7 is fixedly connected to the outer wall of the push rod 5, and the disc 7 is used to drive the push rod 5.

Two baffles are provided at the top of the limiting plate 18 to facilitate the rectangular plate 19 to be engaged inside.

[0031] During use, after the stent is inserted into the patient's uterine cavity, air is injected into the annular balloon 4 through the trachea 12, pushing the disc 7. The disc 7 drives the push rod 5 to move, and the push rod 5 drives the cylinder 6 to move through the moving column 3. At the same time, the push rod 5 drives the rectangular plate 19 to move, and the push rod 5 drives the pushing column 13 to compress the second spring 14. The cylinder 6 drives the square block 15 to move, and the square block 15 drives the moving rod 10 to rotate around the cross-section of the square block 15 as the center. The moving rod 10 drives the soft ball 11 to change the shape of the annular balloon 4 to fit the inner wall of the uterine cavity. At the same time, the first spring 8 drives the arc-shaped block 16 to move through the connecting rod 9. The arc-shaped block 16 carries... The movable cushion 17 fits against the inner wall of the annular airbag 4. The rotating disc 7 drives the rectangular plate 19 to rotate via the push rod 5. After the rectangular plate 19 is rotated to the top of the limiting plate 18, it is released. The second spring 14 is released and pushes the push column 13. The push column 13 drives the rectangular plate 19 to engage with the limiting plate 18 via the push rod 5. When it is necessary to remove it, the rectangular plate 19 is disengaged from the limiting plate 18 by pushing the disc 7 and then released. The second spring 14 is released and pushes the moving column 3 to reset. At the same time, the arc block 16 and the soft ball 11 are reset. The gas inside the annular airbag 4 is discharged through the trachea 12, and the stent is removed from the uterine cavity.

[0032] like Figure 5 As shown, a drainage tube 20 is installed on the inner wall of the annular airbag 4. The drainage tube 20 is used to drain the internal liquid. A discharge tube 21 is snapped into the bottom end of the drainage tube 20. An installation block 22 is fixedly connected to the bottom end of the outer wall of the drainage tube 20. An installation groove is opened at the bottom end of the installation block 22. A circular plate 23 is fixedly connected to the outer wall of the discharge tube 21. Two limiting grooves that are mirror-distributed are opened on the inner wall of the discharge tube 21 and the outer wall of the installation block 22.

[0033] like Figure 6 As shown, a trapezoidal block 24 is slidably connected to the inner wall of the limiting groove. The upper and lower ends of the trapezoidal block 24 are provided with inclined surfaces. A third spring 25 is connected between the bottom end of the trapezoidal block 24 and the bottom of the limiting groove. The third spring 25 is used to push the trapezoidal block 24. The inner wall of the support rod 2 is provided with a groove to facilitate the installation of the drainage pipe 20, and the drainage pipe 20 is a flexible hose.

[0034] During use, the fluid inside the uterine cavity is discharged through the drainage tube 20. After prolonged use, the discharge tube 21 needs to be replaced. Pulling the round plate 23 causes the discharge tube 21 to move. The discharge tube 21 squeezes the trapezoidal block 24. Since the contact surface is inclined, the trapezoidal block 24 is forced to compress the third spring 25. The third spring 25 is forced to retract. After removing the discharge tube 21, the installation block 22 and one end of the drainage tube 20 are disinfected. The third spring 25 is released and pushes the trapezoidal block 24 to reset. When installing the discharge tube 21, the top of the discharge tube 21 is inserted into the installation groove. When the top of the discharge tube 21 contacts the inclined surface of the trapezoidal block 24, the trapezoidal block 24 is forced to retract. When the trapezoidal block 24 passes through the limiting groove, the third spring 25 is released and pushes the trapezoidal block 24 to engage the discharge tube 21.

[0035] The specific implementation method is as follows: After the stent is inserted into the patient's uterine cavity, air is injected into the annular balloon 4 through the trachea 12, pushing the disc 7. The disc 7 drives the push rod 5 to move. The push rod 5 drives the cylinder 6 to move through the moving column 3. At the same time, the push rod 5 drives the rectangular plate 19 to move, and the push rod 5 drives the pushing column 13 to compress the second spring 14. The cylinder 6 drives the square block 15 to move. The square block 15 drives the moving rod 10 to rotate around the cross-section of the square block 15 as the center. The moving rod 10 drives the soft ball 11 to change the shape of the annular balloon 4 to fit against the inner wall of the uterine cavity. At the same time, the first spring 8 drives the arc-shaped block 16 to move through the connecting rod 9. The arc-shaped block 16 drives the soft pad 17 to fit against the inner wall of the annular balloon 4. The rotating disc 7 drives the push rod 5 to move the soft ball 11 to fit against the inner wall of the annular balloon 4. The rectangular plate 19 rotates until it reaches the top of the limiting plate 18, at which point it is released. The second spring 14 is then released, pushing the pushing column 13. The pushing column 13, through the push rod 5, causes the rectangular plate 19 to engage with the limiting plate 18. When removal is required, the disc 7 is pushed and rotated, causing the rectangular plate 19 to disengage from the limiting plate 18 and be released. The second spring 14 is then released, pushing the moving column 3 to reset. Simultaneously, the arc-shaped block 16 and the soft ball 11 are reset. Furthermore, the gas inside the annular balloon 4 is expelled through the trachea 12, allowing the stent to be removed from the uterine cavity. The doctor can adjust the position and shape of the stent according to the specific condition of the patient's uterine cavity to better adapt it to the shape of the uterine cavity, ensuring the treatment effect and reducing the risk of complications such as bleeding.

[0036] Fluid inside the uterine cavity is drained through the drainage tube 20. After prolonged use, the drainage tube 21 needs to be replaced. Pulling the circular plate 23 moves the drainage tube 21, which then squeezes the trapezoidal block 24. Because the contact surface is inclined, the trapezoidal block 24 is forced to compress the third spring 25, which then retracts. After removing the drainage tube 21, the mounting block 22 and one end of the drainage tube 20 are disinfected. The third spring 25 is released, pushing the trapezoidal block 24 back to its original position. When installing the drainage tube 21, the top end of the drainage tube 21 is inserted into the mounting groove. When the top end of the drainage tube 21 contacts the inclined surface of the trapezoidal block 24, the trapezoidal block 24 retracts. When the trapezoidal block 24 passes through the limiting groove, the third spring 25 is released, pushing the trapezoidal block 24 to engage the drainage tube 21. The operation is simple and convenient, effectively reducing the risk of infection caused by contamination of the drainage tube 21 and improving the patient's health.
