The first penetrator delivers the suture from the second penetration point so that the suture is connected to one end of the bridge connecting strip. A pre-knot is arranged on the first penetrator at the rear of the suture. The first penetrator passes through the first penetration point and connects to the other end of the bridge connecting strip. When the first penetrator withdraws from the first penetration point, it brings out the other end of the bridge connecting strip, so that the bridge connecting strip passes through the pre-knot and is withdrawn. The withdrawal of the bridge connecting strip drives the suture to pass through the pre-knot to form a suture loop; at least two suture pairs form at least two suture loops. Taking two suture pairs as an example, the bridge connecting strips corresponding to the two suture pairs are cross-over and overlapped with each other, and the two suture loops formed are crossed inside the vascular rupture.

[0023] Specifically, the cross-over and overlapping structure of the bridge connecting strips is that the middle part of the bridge connecting strip on one side is angled around the middle part of the bridge connecting strip on the other side. Furthermore, the bridge connecting strip on one side is entangled when passing around the bridge connecting strip on the other side. The cross-over and overlapping arrangement of the bridge connecting strips determines the structural form of the cross-over suture line loop that is finally formed.

[0024] Specifically, both ends of the bridge connecting strip are provided with developing sections for positioning in the blood vessel so that the surgeon can better observe the surgical status.

[0026] Different from the above-mentioned implementation, the present embodiment also provides another possible implementation of the separate suture structure, the first penetrator includes a first guide needle, a pluggable first connector and a pull-out line arranged at the front end of the first guide needle, the second penetrator includes a second guide needle and a pluggable second connector arranged at the front end of the second guide needle, two bridge connecting strips located inside the vascular rupture cross, and both ends of the bridge connecting strip are arranged as plug-in interfaces for connecting the first connector or the second connector, the second connector is connected to the suture, the first connector is connected to the pull-out line, the pre-tied sleeve behind the suture is arranged on the pull-out line in the same column, the first guide needle and the second guide needle penetrate the blood vessel and are inserted into the plug-in interfaces at both ends of the bridge connecting strip; the second guide needle is withdrawn outward, and the second connector drives the suture to fall off the second guide needle; the first guide needle is withdrawn outward, and the first connector drives the pull-out line to fall off the first guide needle, the pull-out line is withdrawn outward, the pull-out line drives the bridge connecting strip, thereby driving the suture to pass through the pre-tie to form a suture loop, and the two cross-distributed bridge connecting strips make the two suture loops cross.

[0027] The present embodiment further provides a vascular rupture suture piece 2 including a separate suture structure, the vascular rupture suture piece 2 including a separate suture structure and receiving bases 2-3 preset in the vascular rupture corresponding to the number of suture pairs, the multiple receiving bases 2-3 can be set to be operated separately or fixed as a whole for unified operation, the receiving base 2-3 is hinged with a guide column extending outside the vascular rupture, the first penetrator and the second penetrator of the suture pair are respectively arranged on both sides of the guide column, the first penetrator and the second penetrator are used to move toward the receiving base to penetrate the blood vessel, the first penetrator and the second penetrator play a guiding role during the penetration process, and the receiving base 2-3 is provided with a receiving groove for receiving the first penetrator and the second penetrator; see for details Figure 2 and Figure 3Two wireless guide needles 2-4 are located on one side of the guide column, and two wired guide needles 2-5 are located on the other side of the guide column. The two bridge connecting strips 2-1 of the separate suture structure are cross-stacked and suspended on the receiving groove of the receiving base 2-3 in a detachable connection manner. The four sockets of the two bridge connecting strips 2-1 are respectively facing the wireless guide needle 2-4 or the wired guide needle 2-5. When in use, the guide column carries the receiving base 2-3 and is inserted obliquely from the rupture of the blood vessel, and the guide column is rotated to pull the receiving base upward. 2-3 makes it stick to the inner wall of the blood vessel. At this time, the wireless guide needle 2-4 and the wired guide needle 2-5 are located on both sides of the blood vessel rupture, and the connectors at both ends of the bridge connecting strip 2-1 are also located on both sides of the blood vessel rupture. The wireless guide needle 2-4 and the wired guide needle 2-5 are pushed downward along the guide rod, and the first connector of the wireless guide needle 2-4 and the second connector of the wired guide needle 2-5 are inserted into the connectors at both ends of the bridge connecting strip 2-1 along the connecting groove, and the bridge connecting strip 2-1 is pushed off from the connecting base 2-3.

[0028] In the process of forming a cross suture loop, the role of the guide base 2-3 and the guide column is to relatively limit the position of the bridge connecting strip 2-1 and the direction of the connector, and to assist the wireless guide needle 2-4 and the wired guide needle 2-5 to penetrate the blood vessel wall along the guide column and insert into the connector.

[0029] This embodiment also provides a vascular suture device including a vascular rupture suture member 2, such as Figure 1 As shown, it specifically includes a catheter 1, a blood vessel rupture suture piece 2, a row tube 3 and an operating handle 4 connected in sequence. A guide wire hole is provided inside the catheter 1, a guide wire hole entrance is provided at the front end, and a guide wire hole exit is provided at the rear end. A guide wire is inserted into the guide wire hole, and the guide catheter 1 extends into the blood vessel through the blood vessel rupture. The blood vessel rupture suture piece 2 is used to suture the blood vessel rupture. The row tube 3 provides a channel for routing, needle movement or movement of suture threads 2-6, suture guide needles and various control lines. The operating handle 4 is provided with multiple operating structures for controlling and operating the guide needles, suture threads 2-6, the receiving base 2-3, etc.

[0030] like Figure 4 , Figure 5As shown, the blood vessel rupture suture piece 2 also includes a receiving base groove 2-2 for accommodating the receiving base 2-3, the receiving base groove 2-2 is a hollow frame structure, the receiving base 2-3 is located in the receiving base groove 2-2, and a rotating shaft is provided in the middle of the receiving base 2-3 to hinge the receiving base groove 2-2; initially, the receiving base 2-3 is received in the receiving base groove 2-2, and the catheter 1 is sent into the blood vessel from the rupture through the guide wire pre-placed in the blood vessel until the receiving base 2-3 of the blood vessel rupture suture piece 2 is completely extended into the blood vessel, and control lines are connected to both sides of the receiving base 2-3, and the control lines are wound around the receiving base release knob 4-2 of the operating handle 4, and the two ends of the control line are respectively connected to the two sides of the rotating shaft in the middle of the receiving base 2-3, and the forward rotation of the receiving base release knob 4-2 drives the receiving base 2- 3 is rotated to release it from the receiving base groove 2-2, and the receiving base 2-3 is pulled upward to make it close to the inner wall of the blood vessel. The wireless guide needle 2-4 and the guide needle with wire 2-5 are located on both sides of the vascular rupture. The rear ends of the wireless guide needle 2-4 and the guide needle with wire 2-5 are connected to the guide needle push handle 4-1 of the operating handle 4, and the guide needle push handle 4-1 is pushed downward to push the wireless guide needle 2-4 and the guide needle with wire 2-5 to penetrate the blood vessel wall and insert into the bridge connecting strip 2-1, and the wireless guide needle 2-4 and the guide needle with wire 2-5 are withdrawn to form a cross suture loop; after the loop is formed, the receiving base release knob 4-2 is rotated in the opposite direction to put the receiving base 2-3 into the receiving base groove 2-2, and then the blood vessel rupture suture piece 2 and the catheter 1 are withdrawn from the blood vessel rupture, and the suture thread 2-6 is tightened to lock the rupture to achieve blood vessel suture. By pushing the guide needle push handle 4-1 once, two groups of sutures can be sent into the blood vessel at the same time, and the two groups of sutures form a cross in the blood vessel. After all guide needles are withdrawn, the two crossed suture loops realize cross-suturing of the blood vessel rupture.

[0031] In some possible implementations, the ends of the two wireless guide needles 2-4 and the two wired guide needles 2-5 are connected to independent guide needle push handles 4-1. During operation, one group of sutures can be formed into a suture loop first, and then the position of the vascular rupture suture piece 2 at the vascular rupture can be slightly adjusted, and then another group of sutures can be formed into a suture loop. This independent structural form, when used to suture a relatively large vascular rupture, can conveniently adjust the penetration position so that the crossed suture loops can be fixed at a longer distance. For example, when the aperture of the vascular rupture is 1.5-2 times the diameter of the vascular rupture suture piece 2, the vascular rupture suture piece 2 can be first inserted from the end close to the wound, and then the receiving base 2-3 on that side can be unfolded, and the corresponding guide needle can be used to puncture the blood vessel to achieve suturing of the first group of sutures 2-6; then the device is moved to the other side of the wound, and the above operation is repeated to achieve another group of suturing. The two groups of suture loops form a cross inside the blood vessel, and the vascular rupture is tightened and closed from both sides. By widening the positions of the two sets of suture loops on the blood vessel, suturing of larger vascular ruptures can be achieved.

[0032] In summary, the vascular suture device provided in this embodiment can be suitable for suturing large-caliber vascular ruptures, and one vascular suture device can replace the functions of multiple suture devices; and by adjusting the angle, suturing of sutures at different angles can be achieved, thereby increasing the clinical options for doctors; secondly, independent suturing control structures can be used between different sutures to increase the flexibility of suturing operations and expand the range of suturing to make it suitable for suturing large-sized vascular ruptures; finally, the vascular suture device can realize cross-suture loops, cross-lock vascular ruptures, and improve the success rate of suturing large wounds.
