[0032] Please see Figure 1-7This application provides a technical solution: a hemostasis device for cardiothoracic surgery, comprising a housing 1, an installation groove on the housing 1, a movable block 5 slidably installed in the installation groove, a connecting rod 2 fixedly installed on the movable block 5, a handle 3 fixedly installed on the connecting rod 2, an inner cavity on the movable block 5, a first pulley 11 rotatably installed on the side wall of the inner cavity, a connecting shaft fixedly installed on the first pulley 11, a knob 4 fixedly installed through the side wall of the movable block 5, a sliding groove on the housing 1, a fixed plate 7 slidably installed in the sliding groove, and the knob 4 rotatably mounted on the fixed plate 7. Rotating the knob 4 drives the connecting shaft to rotate, thereby driving the first pulley 11 to rotate. Pushing the handle 3 drives the connecting rod 2 to move, thereby driving the movable block 5 to move on the installation groove of the housing 1.

[0033] In the technical solution of this application, such as Figure 1 and 2 As shown, the lower end of the movable block 5 has an opening, on which a hemostatic mechanism can be installed. The hemostatic mechanism includes a U-shaped frame 6 with a through hole. A rotating rod is provided at the through hole, and a second rotating roller 17 is fixedly installed on the rotating rod. A hemostatic bandage 16 is sleeved on the second rotating roller 17, and a first rotating roller 15 is sleeved on the other end of the hemostatic bandage 16. A movable rod is provided on the first rotating roller 15. When the first rotating roller 15 rotates, it will drive the hemostatic bandage 16 to move, so as to stop the bleeding at the place where hemostasis is needed.

[0034] In the technical solution of this application, such as Figure 5 As shown, a groove is provided at one end of the movable rod, and a small spring 13 is fixedly installed in the groove. A sliding rod 10 is fixedly installed on the small spring 13. The diameter of the sliding rod 10 is the same as the diameter of the groove. The small spring 13 can drive the sliding rod 10 to move and reset, and the sliding rod 10 can extend out from the groove.

[0035] In the technical solution of this application, such as Figure 2 and 5 As shown, a first internal spline 8 is provided at the end of the moving rod away from the groove. A baffle is fixedly installed on the moving rod next to the first internal spline 8. A first spring 9 is fixedly installed on the baffle. The other end of the first spring 9 is fixedly installed on the outer wall of the U-shaped frame 6. When the moving rod moves, it will squeeze the first spring 9. After the external force is removed, it will reset under the action of the first spring 9.

[0036] In the technical solution of this application, such as Figure 5As shown, the moving rod is provided with a second internal spline 14 in the middle, and a circular groove is provided on the first rotating roller 15. A fixed sleeve is provided in the circular groove, and an external spline is provided on the fixed sleeve. The second internal spline 14 can cooperate with the external spline in the circular groove, thereby driving the first rotating roller 15 to rotate.

[0037] In the technical solution of this application, such as Figure 4 As shown, a belt 12 is fitted on the first pulley 11, and a second pulley is fitted on the other end of the belt 12. The second pulley is rotatably mounted on the inner cavity of the movable block 5. An installation hole is provided on the second pulley, and a second external spline is provided in the installation hole. When the first pulley 11 rotates, it will drive the belt 12 to move, thereby driving the second pulley to rotate.

[0038] In the technical solution of this application, such as Figure 4 As shown, the second external spline is adapted to the first internal spline 8. When the second external spline and the first internal spline 8 are installed together, the rotation of the second pulley will drive the moving rod to rotate.

[0039] In the technical solution of this application, such as Figure 7 As shown, a rectangular groove is provided on the movable block 5 at the slide rod 10. The width of the rectangular groove is greater than the diameter of the slide rod 10. During disassembly, the slide rod 10 is stretched to move the entire movable rod. Then the slide rod 10 is moved downward to separate the second external spline and the first internal spline 8. The entire hemostasis mechanism is then removed and replaced.

[0040] When adjusting the length during use, push handle 3 to move connecting rod 2, which in turn moves moving block 5 on mounting slot of housing 1 to adjust the length. When hemostasis is required, turn knob 4 to rotate connecting shaft, which in turn rotates first pulley 11. When first pulley 11 rotates, it drives belt 12 to move, which in turn drives second pulley to rotate. The rotation of second pulley drives moving rod to rotate, which in turn drives first rotating roller 15 to rotate. When first rotating roller 15 rotates, it drives hemostatic bandage 16 to move, allowing hemostasis to be applied to the area requiring it. The hemostatic machine can be disassembled when needed. During installation, the slide bar 10 is stretched, causing the entire moving rod to move, thus separating the second external spline and the first internal spline 8. Then, the slide bar 10 is moved downwards, separating the second external spline and the first internal spline 8. The slide bar 10 is then pressed inwards to retract into the groove. The entire hemostasis mechanism is then removed and replaced. During installation, both ends of the moving rod on the hemostasis mechanism are pressed inwards to allow it to slide within the opening of the moving block. When the hemostasis mechanism moves to the point where the second external spline and the first internal spline 8 are installed together, the installation is complete. When endoscopy is required, a miniature camera and supplementary lighting can be installed on the housing for endoscopy.
