[0044] Guide components, two sets of guide components are symmetrically arranged on the upper and lower sides of the bidirectional screw 4, and are used to guide and constrain the moving block 6.

[0045] Depend on Figure 1-Figure 7 It can be seen that a plurality of binding straps 7 are fixedly connected to the outer wall of the flexible arc pad 2 .

[0046] The adapter assembly includes a fixed rod 8, a cylinder 9 and a round rod 10. The two ends of the fixed rod 8 are fixedly connected to the inner wall of the hard plate 1 and the outer wall of the cylinder 9 respectively. One end of the round rod 10 is fixedly connected to one end of the bidirectional screw 4. The end of the round rod 10 away from the bidirectional screw 4 is rotatably connected to the inner wall of the cavity of the cylinder 9.

[0047] The driving assembly includes an installation box 11, a servo motor 12, a connecting shaft 13, a first pulley 14, a belt body 15 and a controller 16. The installation box 11 is fixedly installed on an outer side wall of the hard board 1, and the servo motor 12 is fixedly installed inside the installation box 11. The output end of the servo motor 12 passes through the inner wall of the installation box 11 and extends to the outside side and is fixedly connected to one end of the connecting shaft 13. The first pulley 14 is fixedly installed on the outer wall of the connecting shaft 13.

[0049] The guide assembly includes a plate 19, a guide rod 20, a slip ring 21 and a docking rod 22. One end of several plates 19 is fixedly connected to a side wall inside the hard plate 1, a guide rod 20 is fixedly connected between two plates 19, the slip ring 21 is movably mounted on the outer wall of the guide rod 20, and the two ends of the docking rod 22 are respectively fixedly connected to the outer wall of the slip ring 21 and the outer wall of the moving block 6.

[0050] As can be seen from the above, when in use, the medical staff places the hard board 1 on one side of the abdomen of the parturient, and further fixes it with the strap 7, wherein the controller 16 is electrically controlled and connected to the servo motor 12, so the medical staff uses the controller 16 to drive the servo motor 12. At this time, the servo motor 12 drives the connecting shaft 13 and the first pulley 14 to rotate, and through the action of the belt body 15, further drives the bidirectional screw 4 to rotate, and the moving block 6 is guided and constrained by the guide assembly, so that the two moving blocks 6 move relative to each other, and further drives the two scrapers 18 to move relative to each other, and then facilitates the use of the two scrapers 18 to tighten the skin tissue on both sides of the parturient's wound, which is conducive to the healing of the wound, and the structural design is humanized.

[0051] Embodiment 2:

[0052] A hard plate 1, with two flexible arc pads 2 symmetrically and fixedly connected at both ends of the hard plate 1;

[0053] A protective cover 3, which is fixedly arranged on a side wall of the hard plate 1;

[0054] A bidirectional screw 4, which is installed on one side of the hard plate 1 through an adapter assembly and is arranged inside the protective cover 3;

[0055] A second pulley 5, which is fixedly mounted on the outer wall of the middle section of the bidirectional screw 4;

[0056] A driving assembly, which is disposed on one side of the outside of the hard plate 1 and is used to drive the second pulley 5 to rotate;

[0057] Moving blocks 6, two moving blocks 6 are symmetrically and movably connected to the outer wall of the bidirectional screw 4;

[0058] A tightening component, which is arranged on one side of the moving block 6 and is used to tighten the tissues on both sides of the wound;

[0059] Guide components, two sets of guide components are symmetrically arranged on the upper and lower sides of the bidirectional screw 4, and are used to guide and constrain the moving block 6.

[0060] refer to Figure 5 and Figure 6 As shown, the outer wall of the protective cover 3 is symmetrically and fixedly connected with two airbag bags 23, one side wall of the sheet plate 19 is fixedly connected with an air cylinder 24, the outer wall of the slip ring 21 is fixedly connected with a mounting plate 25, one side wall of the mounting plate 25 is fixedly connected with an axle rod 26, the inner wall of the cavity of the air cylinder 24 is movably connected with a piston disk 27, and one end of the axle rod 26 away from the mounting plate 25 is fixedly connected to a side wall of the piston disk 27.

[0061] A ventilation hose 28 is connected to the outer wall of the rear end of the air cylinder 24 , and a through hole is opened on the side wall of the protective cover 3 . One end of the ventilation hose 28 away from the air cylinder 24 passes through the through hole and is connected to the outer wall of the airbag bag 23 .

[0062] As can be seen from the above, when the two scrapers 18 are used to tighten the tissues on both sides of the parturient's wound, the two sides are concave. In order to prevent the tightened tissues from spreading to the concave places on both sides, the airbag bag 23 is provided to facilitate filling the concave places. In specific use, when the medical staff drives the servo motor 12 to drive the two moving blocks 6 to move relatively, the moving block 6 drives the scraper 18 to move while also driving the slip ring 21 to slide. The slip ring 21 further drives the shaft rod 26 to move, and the shaft rod 26 further drives the piston disc 27 to move the compressed air on the inner wall of the air cylinder 24 cavity, so that the air is squeezed into the airbag bag 23 through the ventilation hose 28. The swelling and filling of the airbag bag 23 prevents the tissues on both sides of the wound from spreading to the concave places to a certain extent, thereby accelerating the healing of the wound.

[0063] Among them, when two relatively moving scrapers 18 are used to tighten the tissues on both sides of the parturient's wound, the greater the degree of tightening, the more obvious the protrusion of the tissue at the wound, which further leads to a greater degree of depression on both sides. When the degree of tightening is greater, the distance moved by the moving block 6 is greater, and the distance moved by the piston disk 27 inside the air cylinder 24 is greater, which further leads to more gas injected into the airbag bag 23, so it is convenient to fill larger depressed areas, and the structural design is user-friendly.
