[0003] Currently, during the process of surgical vascular suture, most are carried out by doctors holding a suture needle to perform processes such as threading and suturing. During the suture process, the blood vessel will swing, and the suture needle will exert a certain pressure on the blood vessel, causing the blood vessel to be compressed and wrinkled, thus affecting the suture of the blood vessel. At the same time, each time the suture needle passes through the blood vessel, the distance from the suture position of the blood vessel to the end of the blood vessel is different, thus affecting the suture effect of the blood vessel. In view of this, we propose an auxiliary device for vascular suture in cardiovascular interventional surgery. Content of the Utility Model

Specific embodiments

[0019] 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.

[0020] As Figures 1 to 4 shown, the present utility model provides an auxiliary device for vascular suture in cardiac intervention surgery, (front, back, left, and right are based on the Figure 1 view, F represents the front, and L represents the left), including two first ring bodies 1. The upper left ends of the two first ring bodies 1 are both rotatably provided with second ring bodies 2 through rotating shafts. The first ring body 1 and the second ring body 2 are both arranged in an arc shape. The first ring body 1 and the second ring body 2 can be closed into a closed ring. The interiors of the first ring body 1 and the second ring body 2 are both arranged as cavities. A plurality of first holes 12 for adsorbing blood vessels are opened on the inner sides of the first ring body 1 and the second ring body 2. The inner cavities of the first ring body 1 and the second ring body 2 are formed into a negative pressure, and the blood vessels are adsorbed on the inner walls of the first ring body 1 and the second ring body 2 through the first holes 12. The ends of the first holes 12, the first ring body 1, and the second ring body 2 are all arranged as arc chamfers so as not to damage the blood vessels when adsorbing the blood vessels. For the positions of the first notch 7 and the second notch 8, the first holes 12 can be arranged on both sides of the first notch 7 and the second notch 8 to avoid the situation where the blood vessels cannot be adsorbed through the first holes 12 within the range of the first notch 7 and the second notch 8, thus affecting the adsorption and fixation of the blood vessels.

[0021] A flexible hose 13 is fixedly connected and communicated between the first annular body 1 and the second annular body 2. The flexible hose 13 can be made of medical silicone tube material so that the flexible hose 13 can adapt to the deformation during the rotation and opening / closing of the second annular body 2. The flexible hose 13 can connect the inner cavities of the second annular body 2 and the first annular body 1. Through the first ventilation pipe 5 and the second ventilation pipe 6, the gas in the cavities of the two first annular bodies 1 can be sucked out. Through the flexible hose 13, the gas in the cavities of the two second annular bodies 2 can also be sucked out, so that a negative pressure is formed in the inner cavities of the first annular body 1 and the second annular body 2.

[0022] The first ventilation pipe 5 is welded to the left side of the front second annular body 2, and the second ventilation pipe 6 is welded to the left side of the rear second annular body 2. Both the first ventilation pipe 5 and the second ventilation pipe 6 are set to be L-shaped. The diameter of the first ventilation pipe 5 is larger than that of the second ventilation pipe 6. When the screw rod 18 rotates in the thread groove 19, it will drive the rear second annular body 2 and the first annular body 1 to move back and forth. As a result, the end of the second ventilation pipe 6 can slide in the first ventilation pipe 5 without hindering the movement of the rear second annular body 2 and the first annular body 1. The upper end of the first ventilation pipe 5 on the side close to the second ventilation pipe 6 is connected and welded with a third ventilation pipe 10. When the rotating block 17 abuts against the end of the first support rod 3, the second ventilation pipe 6 slides into the innermost side of the first ventilation pipe 5. At this time, the third ventilation pipe 10 is located in front of the end of the second ventilation pipe 6, so that when the second ventilation pipe 6 slides in the first ventilation pipe 5, the second ventilation pipe 6 will not block the third ventilation pipe 10, preventing the gas in the first annular body 1 and the second annular body 2 from being discharged.

[0023] The upper end of the third ventilation pipe 10 is welded with a support rod 11. The inside of the support rod 11 is set as a cavity and is communicated with the third ventilation pipe 10. The inner cavities of the second annular body 2, the flexible hose 13, the first annular body 1, the first ventilation pipe 5, the second ventilation pipe 6, the third ventilation pipe 10 and the support rod 11 are all interconnected. The left side of the support rod 11 is provided with a second hole 14 for gas discharge. The second hole 14 is externally connected with a negative pressure device, so that the gas in the cavities of the first annular body 1 and the second annular body 2 can be sucked out, forming a negative pressure in the first annular body 1 and the second annular body 2 to adsorb and fix blood vessels. The left end of the support rod 11 is provided with a handle for holding, which is convenient for the taking and using of this auxiliary device.

[0024] The left side of the second front-side ring body 2 is fixed to the fixed end of the movable seat, and the rotating end of the movable seat is fixed to the first support rod 3. The left side of the second rear-side ring body 2 is fixed to the fixed end of the movable seat, and the rotating end of the movable seat is fixed to the second support rod 4. Both the first support rod 3 and the second support rod 4 are arranged in an L shape. A fixing block 16 is welded to the end of the second support rod 4. The fixing block 16 is arranged in a disc shape. A rotating block 17 is sleeved on the fixing block 16. The rotating block 17 can rotate around the fixing block 16. A screw rod 18 is welded to one end of the rotating block 17 close to the first support rod 3. A thread groove 19 adapted to the screw rod 18 is arranged on the side of the first support rod 3 close to the second support rod 4. The screw rod 18 is threadedly arranged in the thread groove 19. By rotating the rotating block 17, the screw rod 18 can be rotated, so that the screw rod 18 can rotate and move in the thread groove 19. Furthermore, the fixing block 16 can be driven by the rotating block 17 to move back and forth, thereby driving the second support rod 4 to move back and forth, so that the distance between the two first ring bodies 1 and the second ring body 2 can be adjusted to adapt to the distance between the two ends of the blood vessel to be sutured.

[0025] A moving member 22 is slidably arranged on the support rod 11. A sliding member 23 is slidably arranged on the moving member 22. A notch is formed around the circumference of the moving member 22. The sliding member 23 is sleeved on the moving member 22 and is located in this notch. The two sides of the notch can limit the sliding member 23 to prevent the sliding member 23 from slipping off the moving member 22 during use. Fixing plates 24 are symmetrically welded to the upper end of the sliding member 23. A third support rod 9 is rotatably arranged between the two fixing plates 24 through a rotating shaft. The third support rod 9 is welded and fixed to the left end of the side of the first support rod 3 close to the second support rod 4.

[0026] A threaded section 15 is arranged on the left side of the support rod 11, and the threaded section 15 is located on the right side of the moving member 22. A thread adapted to the threaded section 15 is arranged on the inner side of the moving member 22. The moving member 22 can be threadedly sleeved on the threaded section 15. By sliding the moving member 22 left and right on the support rod 11, the two second ring bodies 2 can be respectively closed or opened with the two first ring bodies 1. When the moving member 22 moves to the right, the second ring body 2 can be closed with the first ring body 1, and by screwing the moving member 22 onto the threaded section 15, the closed state of the second ring body 2 and the first ring body 1 can be maintained. When the moving member 22 rotates on the threaded section 15, the sliding member 23 slides on the moving member 22 without affecting the third support rod 9.

[0027] A groove 20 is formed at the inner end of the first air pipe 5 close to the second air pipe 6. A sealing ring 21 that abuts against and can slide on the second air pipe 6 is arranged in the groove 20. The sealing ring 21 can seal the gap between the outer wall of the second air pipe 6 and the inner wall of the first air pipe 5, so as to further ensure the gas flow and the formation of negative pressure in the first ring body 1 and the second ring body 2.

[0028] At the upper left ends of both first annular bodies 1, second notches 8 are provided. The lower left end of the second annular body 2 is rotatably arranged in the second notch 8. At the upper right ends of both first annular bodies 1, first notches 7 are provided. The lower right end of the second annular body 2 can be inserted into the first notch 7. By adjusting the distance that the moving member 22 screws into the threaded section 15, the depth of insertion of the lower right end of the second annular body 2 into the first notch 7 can be adjusted, so that the size of the ring formed when the first annular body 1 and the second annular body 2 are closed can be adjusted to adapt to blood vessels of different sizes. The provision of the second notch 8 ensures that when the second annular body 2 rotates, the first annular body 1 will not obstruct the rotation of the second annular body 2.

[0029] Except for the flexible tube 13 and the sealing ring 21, the present utility model is preferably made of titanium alloy, which can be set according to actual needs.

[0030] The working principle and process of the present utility model are as follows:

[0031] When in use, first, by rotating the rotating block 17, the second rod 4 can be moved closer to or farther away from the first rod 3, so that the first annular body 1 and the second annular body 2 at the rear can be moved forward or backward, thereby adjusting the distance between the two first annular bodies 1 and the second annular body 2 to adapt to the distance between the two ends of the blood vessel to be sutured. Subsequently, the moving member 22 is pushed towards the threaded section 15, so that the third rod 9 moves closer to the second annular body 2, thereby causing the first rod 3 and the second rod 4 to move closer to the second annular body 2. The first rod 3 will push the second annular body 2 at the front towards the first notch 7 at the front to rotate, and the second rod 4 will push the second annular body 2 at the rear towards the first notch 7 at the rear to rotate, so that the two second annular bodies 2 are respectively inserted into the two first notches 7, thereby closing the second annular body 2 and the first annular body 1. At this time, the moving member 22 abuts against the threaded section 15, and the moving member 22 is rotated to screw the moving member 22 onto the threaded section 15, thereby maintaining the closed state of the second annular body 2 and the first annular body 1, so that the two ends of the blood vessel can respectively pass through the interiors of the two first annular bodies 1 and the second annular body 2;

[0032] A negative pressure device is externally connected to the second hole 14. The gas in the first annular body 1 at the front side is transported through the first air pipe 5 to the third air pipe 10, and the gas in the first annular body 1 at the rear side is transported through the second air pipe 6 to the third air pipe 10, and then is sucked out through the cavity arranged in the support rod 11 by the second hole 14. The second annular body 2 is communicated with the inner cavity of the first annular body 1 through a hose 13, so that the gas in the two second annular bodies 2 can also be discharged. Thus, a negative pressure can be formed in the cavities of the first annular body 1 and the second annular body 2, and the blood vessel can be adsorbed on the inner walls of the first annular body 1 and the second annular body 2 through the first hole 12. The pressure of the negative pressure needs to be adjusted according to blood vessels of different sizes to avoid damaging the blood vessel due to excessive pressure, so that when suturing the blood vessel, the blood vessel will not swing. Moreover, when adsorbing the blood vessel, the two ends of the blood vessel can be slightly expanded. Thus, when using a suture needle to penetrate the blood vessel for suturing, the blood vessel will not be greatly deformed and wrinkled due to being pressed, so as not to affect the suturing of the blood vessel. At the same time, after the blood vessel is adsorbed on the inner walls of the first annular body 1 and the second annular body 2, the sides of the first annular body 1 and the second annular body 2 can play a role in positioning the position sutured by the suture needle, so that the distance between the position where the suture needle sutures the blood vessel and the end of the blood vessel can be kept the same each time.
