[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limitations of the present invention. On the contrary, embodiments of the present invention include all changes, modifications and equivalents that fall within the spirit and connotation of the appended claims.

[0037] A magnetic vascular anastomosis device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figure 1-Figure 7 As shown, an electromagnetic vascular anastomosis device according to an embodiment of the present invention comprises a mounting seat 1, a first fixing seat 2, a second fixing seat 3 and two groups of split magnetic pipes 7, wherein the first fixing seat 2 is bolted to the surface of the mounting seat 1, the second fixing seat 3 is slidably connected to the surface of the mounting seat 1 and is located on one side of the first fixing seat 2, and the second fixing seat 3 is fixedly connected to the surface of the mounting seat 1 by tightening the handle 4; the two groups of split magnetic pipes 7 are rotatably connected to the inner wall of the first fixing seat 2 and the inner wall of the second fixing seat 3, respectively, and the positions are corresponding; the split magnetic pipe 7 comprises a split pipe body 71, a cylindrical through groove 72 and a magnetic ring 73, wherein the split pipe body 71 is rotatably connected to the inner wall of the first fixing seat 2 and the inner wall of the second fixing seat 3, respectively, and the positions are corresponding, the cylindrical through groove 72 is opened at the center of the inner end surface of the split pipe body 71, and the magnetic ring 73 is fixedly connected to the inner end surface of the split pipe body 71 and is located outside the cylindrical through groove 72; the magnetic ring 73 in the two groups of split magnetic pipes 7 is fixed by magnetic attraction.

[0039] Specifically, when in use, firstly, the two groups of split magnetic pipes 7 are respectively put on the outside of the left blood vessel and the outside of the right blood vessel; then, one end of the left blood vessel is turned outward and put on the annular portion 711 of the inner end surface of the split magnetic pipe 7 on the first fixing seat 2, and then, the right blood vessel is turned outward and put on the annular portion 711 of the inner end surface of the split magnetic pipe 7 on the second fixing seat 3; after the putting is completed, the tightening handle 4 is loosened, and then the second fixing seat 3 is pushed toward the side of the first fixing seat 2 until the two groups of magnetic rings 73 are magnetically connected. After the two groups of magnetic rings 73 are fixed by magnetic attraction, one end of the left blood vessel and one end of the right blood vessel are fixed respectively and made to fit together, and then the handle 4 is tightened; then the parts of the protruding outer edge of the annular portion 711 at one end of the left blood vessel and one end of the right blood vessel are sutured by needle and thread. During the suturing process, the rotating handle 83 can synchronously drive the two groups of split magnetic pipes 7 to rotate, and the synchronous rotation of the two groups of split magnetic pipes 7 changes the suturing position. After the suturing is completed, the outer pipe 6 is separated from the inner pipe 5, so as to facilitate the removal of the device from the blood vessel.

[0040] In one embodiment of the present invention, Figure 2As shown, annular portions 711 are integrally formed on both end surfaces of the split pipe body 71 , and arc-shaped grooves 712 are evenly formed on the surface of the annular portion 711 located on the inner end surface of the split pipe body 71 .

[0041] It should be noted that the annular portion 711 described in this embodiment supports the blood vessel. By placing the blood vessel on the annular portion 711, suturing operation is facilitated, and the arc-shaped groove 712 is designed to facilitate threading, which is highly practical and has good use effect.

[0042] In one embodiment of the present invention, Figure 1-Figure 4 As shown, the split pipe body 71 includes an inner pipe 5 and an outer pipe 6, wherein the inner pipe 5 is respectively slidably connected to the inner wall of the first fixed seat 2 and the inner wall of the second fixed seat 3, the outer pipe 6 is adapted to the outer dimensions of the inner pipe 5, the outer pipe 6 is clamped and fixed on the surface of the inner pipe 5, and is respectively slidably connected to the inner wall of the first fixed seat 2 and the inner wall of the second fixed seat 3.

[0043] It should be noted that the design of the inner tube 5 and the outer tube 6 described in this embodiment facilitates the removal of the device from the blood vessel by separating the outer tube 6 from the inner tube 5 after suturing, thereby achieving good use effect.

[0044] In one embodiment of the present invention, Figure 4 As shown, a clamping hole 100 and a clamping column are respectively provided at corresponding positions on the surface of the inner pipe 5 and the surface of the outer pipe 6, and the clamping hole 100 is clamped and fixed with the clamping column.

[0045] It should be noted that the clamping hole 100 and the clamping column described in this embodiment facilitate positioning and connection, and also improve its structural stability.

[0046] In one embodiment of the present invention, Figure 1-Figure 5 As shown, the mounting seat 1 also includes a synchronous rotation mechanism 8, which includes a left transmission key rod 81, a left gear 82, a turning handle 83, a right transmission key cylinder 84 and a right gear 85, wherein the left transmission key rod 81 is rotatably connected to the inner wall of the first fixed seat 2, the left gear 82 is rotatably connected to the surface of the first fixed seat 2 and is connected to one end of the left transmission key rod 81, the turning handle 83 is fixedly connected to the surface of the left gear 82, the right transmission key cylinder 84 is rotatably connected to the inner wall of the second fixed seat 3 and corresponds to the position of the left transmission key rod 81, one end of the right transmission key cylinder 84 passes through the outside of the second fixed seat 3 and is slidably connected to the outer surface of one end of the left transmission key rod 81, the other end of the right transmission key cylinder 84 passes through the outside of the second fixed seat 3 and is fixedly connected to the right gear 85; the surface of the annular portion 711 located on the outer end surface of the split pipeline body 71 is integrally formed with teeth 713, and the teeth 713 are respectively meshed and connected with the left gear 82 and the right gear 85.

[0047] It should be noted that the synchronous rotation mechanism 8 described in this embodiment is used to synchronously drive the two groups of split magnetic pipes 7 to rotate to achieve suturing position switching.

[0048] Specifically, before suturing a blood vessel, the doctor will use a hemostatic forceps to clamp the blood vessel and deliberately leave a set length of the blood vessel. This not only prevents the blood vessel from being tightened and provides the doctor with sufficient operating space, but also enables the doctor to easily flip the blood vessel, thereby facilitating the suturing operation on the other side of the blood vessel. When the device is in use, the handle 83 is turned, and the rotation of the handle 83 synchronously drives the left gear 82, the left transmission key rod 81, the right transmission key cylinder 84 and the right gear 85 to rotate. The rotation of the left gear 82 and the right gear 85 synchronously drives the two groups of split pipe bodies 71 to rotate through the teeth 713. The rotation of the two groups of split pipe bodies 71 synchronously drives the two groups of blood vessels to rotate, thereby realizing the switching of the suturing position, and the use effect is good.

[0049] In one embodiment of the present invention, Figure 3-Figure 4 and Figure 6-Figure 7 As shown, the split pipeline body 71 also includes a separation mechanism 9, which is symmetrically arranged on the surface of the first fixed seat 2 and the surface of the second fixed seat 3, and is located on the outside of the inner pipeline 5, wherein the separation mechanism 9 includes a fixed plate 91, a lifting rod 92, a pressure plate 93, a conical seat 94, a spring 95 and a conical groove 96, wherein the fixed plate 91 is fixedly connected to the surface of the first fixed seat 2 and the second fixed seat 3, respectively, the lifting rod 92 is slidably connected to the inner wall of the fixed plate 91, one end of the lifting rod 92 passes through the outside of the fixed plate 91 and is fixedly connected to the pressure plate 93, the other end of the lifting rod 92 passes through the outside of the fixed plate 91 and is fixedly connected to the conical seat 94, the spring 95 is sleeved on the outside of the lifting rod 92, and is fixedly connected to the surface of the fixed plate 91 and the pressure plate 93, respectively, the conical groove 96 is symmetrically opened on the surface of the outer pipeline 6, and corresponds to the position of the conical seat 94, the conical seat 94 is adapted to the internal outer dimensions of the conical groove 96, and the conical seat 94 is slidably connected to the inner wall of the conical groove 96.

[0050] It should be noted that the separation mechanism 9 described in this embodiment facilitates the rapid separation of the inner pipe 5 from the outer pipe 6 .

[0051] Specifically, when in use, the pressing plate 93 is pressed, and the pressing plate 93 is subjected to the force to synchronously drive the lifting rod 92 and the conical seat 94 to move, and squeeze the spring 95. When the conical seat 94 enters the conical groove 96, it will synchronously squeeze the conical groove 96. After being squeezed, the conical groove 96 drives the outer pipe 6 to move and separate from the inner pipe 5, thereby facilitating the removal of the outer pipe 6, and the use effect is good.

[0052] The magnetic vascular anastomosis device proposed by the present invention has a specific method of use as follows: first, two groups of split magnetic pipes 7 are respectively placed on the outside of the left blood vessel and the outside of the right blood vessel; then, one end of the left blood vessel is turned outward and placed on the annular portion 711 of the inner end surface of the split magnetic pipe 7 on the first fixing seat 2; then, one end of the right blood vessel is turned outward and placed on the annular portion 711 of the inner end surface of the split magnetic pipe 7 on the second fixing seat 3; after the placement is completed, the tightening handle 4 is loosened, and then the second fixing seat 3 is pushed toward the side of the first fixing seat 2 until the two groups of magnetic rings 73 are magnetically fixed; after the two groups of magnetic rings 73 are magnetically fixed, one end of the left blood vessel and one end of the right blood vessel are respectively fixed and fit together, and then the tightening handle 4 is tightened. Then, the protruding outer edge of the annular portion 711 of one end of the left blood vessel and one end of the right blood vessel are sutured by needle and thread; during the suturing process, the suturing position can be changed by rotating the turning handle 83; after the suturing is completed, the outer pipe 6 is separated from the inner pipe 5, so that the device can be easily removed from the blood vessel.

[0053] In summary, the magnetic vascular anastomosis device and its use method in the embodiment of the present invention are provided with a split magnetic pipe 7. This pipe can be installed on the outside of the blood vessel to effectively support the inside of the blood vessel suture end, thereby completely solving the problem of insufficient support for the inside of the blood vessel in the traditional method.
