Description

Technical Field

[0001] This utility model relates to the field of vascular suture technology, and in particular to a vascular anastomosis auxiliary ring. Background Technology

[0002] Large vessel surgeries such as type A aortic dissection often involve vascular anastomosis. In the case of collapsed vessels, the vessels are often irregular. During suturing, it is necessary to suture evenly and neatly to ensure accurate vascular anastomosis. Otherwise, uneven tension can easily lead to leakage and bleeding. At the same time, anastomosis of irregular shapes is more difficult, and the surgeon's suturing time is longer, which leads to prolonged deep hypothermic circulatory arrest time and aggravates the patient's damage.

[0003] Therefore, it is necessary to provide a new vascular anastomosis assist ring to solve the above-mentioned technical problems. Summary of the Invention

[0004] The technical problem solved by this utility model is to provide a vascular anastomosis auxiliary ring that can make blood vessels expand uniformly in a ring shape to a physiologically full state, improve the uniformity and efficiency of wiring, shorten the vascular anastomosis time and improve the quality of anastomosis.

[0005] To solve the above-mentioned technical problems, the vascular anastomosis auxiliary ring provided by this utility model includes: an inner ring mechanism disposed in the outlet of an artificial blood vessel or an autologous blood vessel, the inner ring mechanism being used to assist in the anastomosis of the artificial blood vessel or autologous blood vessel, the inner ring mechanism including a first annular piece, the first annular piece being in contact with the inner wall of the artificial blood vessel, a plurality of grooves being provided on one side of the first annular piece, and a locking block and a locking groove being provided at both ends of the first annular piece, the locking block being engaged in the locking groove.

[0006] Preferably, an outer ring mechanism is fitted on the outside of the artificial blood vessel with an inner diameter greater than 4 mm, which is fitted on the outside of the inner ring mechanism, and the outer ring mechanism is fitted on the outside of the corresponding inner ring mechanism.

[0007] Preferably, the outer ring mechanism includes a second annular plate, and a connecting block is fixedly installed on one side of each of the second annular plates. The same adjusting bolt is installed on both connecting blocks, and the adjusting bolt passes through both connecting blocks and is threadedly connected to at least one of the connecting blocks.

[0008] Preferably, the depth of the groove is 2-5 mm.

[0009] Preferably, the width of the first annular piece is 3-8 mm.

[0010] Compared with related technologies, the vascular anastomosis auxiliary ring provided by this utility model has the following beneficial effects:

[0011] This invention provides a vascular anastomosis auxiliary ring that enables the blood vessel to expand uniformly in a ring shape to a physiologically full state. The addition of grooves makes the wiring more uniform and faster, shortens the vascular anastomosis time, improves the anastomosis quality, and improves the wound healing efficiency of patients. Vascular rings with different inner diameters are involved according to different blood vessel inner diameters and different degrees of freeness. At the same time, an outer ring mechanism can be selected according to different blood vessel inner diameters. Both the inner ring mechanism and the outer ring mechanism can be repeatedly sterilized and reused. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of the vascular anastomosis auxiliary ring provided by this utility model; Figure 2 for Figure 1 A top view of the inner ring mechanism shown. Figure 3 for Figure 2 The diagram shows the structure of the inner ring mechanism after it has been unfolded. Figure 4 for Figure 1 The diagram shows the installation structure of the inner and outer ring mechanisms. The vascular anastomosis auxiliary ring includes: an inner ring mechanism 2 disposed within the outlet of the artificial blood vessel 1 or the autologous blood vessel.

[0019] The inner ring mechanism 2 is used to assist in the anastomosis of the artificial blood vessel 1 or the autologous blood vessel. It can assist in the anastomosis of artificial blood vessels 1 with each other, or the anastomosis of artificial blood vessels 1 with autologous blood vessels, or the anastomosis of autologous blood vessels with each other. It mainly assists in wiring. After wiring, the loop is untied and then knotted. The inner ring mechanism 2 includes a first annular piece 21. The first annular piece 21 is in contact with the inner wall of the artificial blood vessel 1. A plurality of grooves 22 are provided on one side of the first annular piece 21. The two ends of the first annular piece 21 are respectively provided with a locking block 23 and a locking groove 24. The locking block 23 is engaged in the locking groove 24.

[0020] An outer ring mechanism 3 is fitted on the outside of the artificial blood vessel 1 with an inner diameter greater than 4 mm, which is fitted on the outside of the inner ring mechanism 2. The outer ring mechanism 3 is fitted on the outside of the corresponding inner ring mechanism 2.

[0021] The outer ring mechanism 3 includes a second annular plate, and a connecting block 4 is fixedly installed on one side of the second annular plate. The same adjusting bolt 5 is installed on the two connecting blocks 4. The adjusting bolt 5 passes through the two connecting blocks 4 and is threadedly connected to at least one of the connecting blocks 4.

[0022] The depth of the groove 22 is 2-5mm.

[0023] The width of the first annular piece 21 is 3-8 mm.

[0024] In actual operation, if only the inner ring mechanism 2 (single ring) is used, select the first ring piece 21 which is 2-4 mm larger than the inner diameter of the blood vessel. Use a tool to put the inner ring mechanism 2 into the blood vessel and suture it. Then use a tool to remove the card block 23 from the card slot 24 and then remove the first ring piece 21.

[0025] In actual operation, if the tissue is relatively thick or during suturing, both the inner ring mechanism 2 and the outer ring mechanism 3 (double rings) are used. The installation and removal of the inner ring mechanism 2 are the same as the single ring operation method described above. After the outer ring mechanism 3 is fitted on the outside of the blood vessel, the inner diameter of the second ring piece can be adjusted by adjusting the distance between the two connecting blocks 4 through the adjusting bolt 5, so that the inner diameter of the outer ring mechanism 3 is in close contact with the blood vessel, thereby facilitating the suturing of the blood vessel and the artificial blood vessel.
