Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-4 and Figure 7 , the present utility model provides a technical solution: a device for preventing intrauterine adhesions after intrauterine surgery, including an isolation pad 1 and a threaded sleeve 3 provided on the isolation pad 1. Specifically, the isolation pad 1 is pear-shaped and can fit the shape of the uterine cavity. Intermittent jacking mechanisms 2 for preventing adhesion of the uterine inner wall are respectively provided on both sides of the isolation pad 1;

[0027] The intermittent jacking mechanism 2 includes an adjusting screw 13 which is rotatably arranged in a threaded sleeve 3. One end of the adjusting screw 13 is rotatably arranged in a bearing seat 12, and the bearing seat 12 is arranged on a wavy top block 11. Separation components which move along with the wavy top block 11 and automatically expand and contract are also arranged on both sides of the isolation pad 1.

[0028] The separation components include transverse separation buckles 14 which are movably arranged in adjusting openings 15. The adjusting openings 15 are arranged on both sides of the isolation pad 1 and can enable the transverse separation buckles 14 to move horizontally in the adjusting openings 15.

[0029] An arc-shaped top block 19 is also arranged on one side of the transverse separation buckle 14. The arc-shaped top block 19 is attached to the wavy top block 11, and the movement of the wavy top block 11 facilitates driving the transverse separation buckle 14 to move.

[0030] After uterine cavity surgery, the isolation pad 1 is placed in the uterine cavity. After being used for a period of time, it will be connected to the adjusting screw 13 through the driving mechanism 4, and then the adjusting screw 13 is rotated. The adjusting screw 13 rotates and moves in the threaded sleeve 3, and at the same time, the adjusting screw 13 rotates in the bearing seat 12. With the movement of the adjusting screw 13, the wavy top block 11 can be driven to move. The wavy top block 11 drives the transverse separation opening to move in the adjusting opening 15 through the arc-shaped top block 19. With the continuous movement of the wavy top block 11, the transverse separation buckle 14 can be reciprocally ejected, and a corresponding gap is formed between the uterine inner wall and the isolation pad 1, avoiding the situation that the uterine inner wall adheres to the isolation pad 1 and ensuring the self-repair of the uterine inner wall.

[0031] Furthermore, the end of the transverse separation buckle 14 is hemispherical, which can prevent damage to the uterine inner wall during the ejection process of the transverse separation buckle 14 and protect the uterine inner wall.

[0032] Furthermore, limit blocks 18 are arranged on both sides of the transverse separation buckle 14. The limit blocks 18 are movably arranged in limit grooves 17, and the limit grooves 17 are arranged on both sides inside the adjusting openings 15. When the transverse separation buckle 14 moves, it drives the limit blocks 18 to move in the limit grooves 17, and the moving stroke of the transverse separation buckle 14 can be limited.

[0033] Furthermore, a return spring 16 is also arranged in the limit groove 17. One end of the return spring 16 is connected to the limit block 18. When the transverse separation buckle 14 moves, it drives the limit block 18 to move, and the limit block 18 compresses the return spring 16. When the wavy top block moves back, through the elastic force of the return spring 16, the transverse separation buckle 14 can be automatically reset and move.

[0034] As a specific embodiment of this application, please refer to Figure 5 and Figure 6, a detachable driving mechanism 4 is further provided at the bottom of the adjusting screw 13. The driving mechanism 4 includes a handle 41. A connecting column 42 is provided on the handle 41. The connecting column 42 is clamped in a positioning groove 45. The positioning groove 45 is provided at one end of the adjusting screw 13, which can connect the handle 41 and the adjusting screw 13. Clamping blocks 43 are provided on both sides of the connecting column 42. The clamping blocks 43 are clamped in clamping grooves 44. The clamping grooves 44 are provided on both sides inside the positioning groove 45, which can clamp the connecting column 42, facilitating the connecting column 42 to drive the adjusting screw 13 to rotate.

[0035] Insert the positioning post on the handle 41 into the positioning groove 45, and at the same time insert the clamping block 43 into the clamping groove 44 to connect the handle 41 and the adjusting screw 13. Then rotate the handle 41. The handle 41 drives the adjusting screw 13 to rotate through the clamping block 43. By the rotation of the adjusting screw 13, the wavy top block 11 can be driven to move. Then, through the ejection of the horizontal separation buckle 14, the uterine inner wall is separated from the isolation pad 1. When it is not necessary to move the wavy top block, the handle 41 can be separated from the adjusting screw 13, and the overall use and operation are convenient.

[0036] Furthermore, the connecting column 42 is made of alloy material, and the connecting column 42 is adsorbed and connected with a magnet block. The magnet block is provided in the positioning groove 45, which can further improve the stability of the connection of the connecting column 42.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
