After the anastomosis bracket 2 slides, the guide plate 3 pushes the two anastomosis rings 6 to approach each other.

[0040] Optionally, it also includes: a rotating shaft 7, which is arranged on the mounting seat 4, and two rotating paddles 5 are respectively rotatably arranged on the rotating shaft 7; a torsion spring 8, which is sleeved on the rotating shaft 7, and the two ends of the torsion spring 8 are respectively arranged on the two rotating paddles 5, and the torsion spring 8 is used to provide a force to move the two rotating paddles 5 away from each other.

[0041] Optionally, the mounting seat 4 further has a clamping portion 401 ; and further comprises: a clamping member 9 , which is arranged on the operating rod 1 and is clamped and matched with the clamping portion 401 .

[0042] In this embodiment, the anastomosis bracket 2 has two relatively arranged sliding rods, and the operating rod 1 has two relatively arranged sliding grooves 502, and the sliding rods are slidably fitted in the sliding grooves 502; the two rotating paddles 5 are rotatably set on the rotating shaft 7, and the two rotating paddles 5 are hinged to each other so that the two rotating paddles 5 can approach each other and dock; the mounting seat 4 passes through the mounting hole 201 on the anastomosis bracket 2 and is engaged with the operating rod 1, and the clamping part 9 is used to clamp and fix the mounting seat 4 and the anastomosis bracket 2.

[0043] In this embodiment, during the operation, the doctor first clamps the two anastomotic rings 6 on the two rotating paddles 5, and then clamps the disconnected blood vessels of the patient on the two anastomotic rings 6 respectively, and then pushes the anastomotic bracket 2 upward, so that the guide plate 3 pushes one of the two rotating paddles 5 upward, and at this time, the torsion spring 8 is subjected to pressure, so that one rotating paddle 5 approaches the other rotating paddle 5, so that the two anastomotic rings 6 are butted, and the disconnected blood vessels of the patient are re-sutured through the two butted anastomotic rings 6. The accuracy of the vascular anastomosis operation is improved, and the doctor's operation is convenient.

[0044] Optionally, the rotating paddle 5 has a mounting portion 501 and a slide groove 502, the slide groove 502 is arranged on both sides of the mounting portion 501, the mounting portion 501 is U-shaped, the anastomotic ring 6 is snap-fitted on the mounting portion 501, and the anastomotic ring 6 has protrusions 601 on both sides, and the protrusions 601 are slidably fitted with the slide groove 502.

[0045] In this embodiment, before the doctor performs the operation, the doctor needs to clamp the two anastomotic rings 6 on the two rotating paddles 5 respectively. The mounting portion 501 is U-shaped and can accommodate one anastomotic ring 6; the anastomotic ring 6 has bosses 402 on both sides, and the mounting portion 501 has slide grooves 502 on both sides. During installation, the doctor can slide the anastomotic ring 6 through the bosses 402 on both sides into the slide grooves 502 on both sides of the mounting portion 501 for installation, making the anastomotic ring 6 easier to install and saving the doctor's operation time. At the same time, the anastomotic ring 6 can be stably clamped on the rotating paddle 5, reducing the occurrence of the anastomotic ring 6 being unstable on the rotating paddle 5 and causing deviation, so that the doctor can more accurately anastomose the disconnected blood vessels of the patient when performing vascular anastomosis.

[0046] Optionally, there are two guide plates 3, which are relatively arranged on the anastomosis bracket 2. The guide plate 3 has a contact end 301, and the contact end 301 is a V-shaped structure. After the anastomosis bracket 2 slides, the two contact ends 301 squeeze the lower ends of the two rotating paddles 5 respectively.

[0047] Optionally, the anastomotic ring 6 has a plurality of through holes 602; it also includes: a plurality of anastomotic staples 603, wherein the two anastomotic rings 6 are respectively provided with a plurality of anastomotic staples 603 in an array along a circumferential direction, a through hole 602 is respectively provided between each two adjacent anastomotic staples 603, and the anastomotic staples 603 on one anastomotic ring 6 respectively cooperate with the through holes 602 on the other anastomotic ring 6 one by one.

[0048] In this embodiment, when the doctor anastomoses the disconnected blood vessels of the patient, the doctor slides the anastomosis bracket 2 upward, and the two guide plates 3 respectively press the two rotating paddles 5 upward, so that the two rotating paddles 5 are close to each other, and the two anastomosis rings 6 are docked. The two guide plates 3 are provided so that the two rotating paddles 5 rotate more quickly and approach each other, so that the two anastomosis rings 6 are docked more quickly, and the disconnected blood vessels of the patient are anastomosed more quickly. The disconnected blood vessels of the patient are anastomosed more quickly, which reduces the patient's bleeding, reduces the occurrence of ischemia in the patient during the operation, and reduces the occurrence of syncope and shock in the patient due to excessive blood loss.

[0049] In this embodiment, before the operation, the doctor can connect the disconnected blood vessels of the patient to the anastomotic rings 6 through the anastomotic staples 603 on the two anastomotic rings 6. When the two anastomotic rings 6 are docked, the several anastomotic staples 603 on one anastomotic ring 6 are plugged and matched with the several through holes 602 on the other anastomotic ring, so that the two anastomotic rings 6 are docked and connected, and the disconnected blood vessels of the patient are docked and anastomosed together again through the two anastomotic rings 6. The provision of the anastomotic staples 603 and the through holes 602 enables the two anastomotic rings 6 to be docked stably, reduces the occurrence of the two anastomotic rings 6 being loose, makes the disconnected blood vessels of the patient anastomosed more tightly, and reduces the occurrence of bleeding problems caused by loose blood vessel anastomosis.

[0050] Optionally, the rotating paddle 5 also has a through slot 503, which passes through the mounting portion 501 and is perpendicular to the mounting portion 501, and also includes: a connecting rod 10, which is arranged on the anastomosis bracket 2 and is located between the two guide plates 3. After the anastomosis staple 603 is inserted into the through hole 602, the connecting rod 10 is coaxial with the through slot 503.

[0051] In this embodiment, the shape of the connecting rod 10 is adapted to the through groove 503. When the two rotating fragments are rotated and docked to dock the two anastomotic rings 6, the doctor can make the anastomotic bracket 2 continue to slide upward to make the connecting rod 10 pass through the through groove 503, and push the two docked anastomotic rings 6 out of the mounting portion 501, thereby reducing the contact between human hands and the anastomotic rings 6, enhancing the sterile environment during surgery, and reducing the occurrence of postoperative infection in patients.

[0052] Optionally, the mounting seat 4 also has a boss 402, which is located between the rotating shaft 7 and the clamping portion 401; and also includes: a protective cover 11, which has a accommodating cavity 1101 and an abutment piece 1102. After the mounting seat 4 is clamped and matched with the protective cover 11, the rotating paddle 5 is located in the accommodating cavity 1101, and the abutment piece 1102 abuts and matches with the boss 402.

[0053] In this embodiment, one patient uses one mounting seat 4, a pair of rotating paddles 5 and a pair of anastomotic rings 6; during factory production, the mounting seat 4 is assembled with the rotating shaft 7 and the two rotating paddles 5 and then put into the protective cover 11, and the accommodating cavity 1101 can accommodate the rotating paddles 5 of the two unfolded turntables and a part of the mounting seat 4.

[0054] In this embodiment, when a patient's operation is completed, the doctor needs to replace the new rotating paddle 5 and the anastomotic ring 6. At this time, the doctor removes the operating rod 1 and the used mounting seat 4 and two rotating paddles 5, installs the new mounting seat 4 on the operating rod 1, and then holds the protective cover 11 and pulls the operating rod 1. At this time, the new mounting seat 4 is subjected to tension and slides backward from the protective cover 11. The boss 402 lifts the ground connection piece, and the new mounting seat 4 and the rotating paddle 5 on the new mounting seat 4 are taken out of the protective cover 11. The doctor can perform the next operation. The setting of the protective cover 11 makes the mounting seat 4 and the rotating paddle 5 in a sterile environment, reduces pollution, and reduces the occurrence of postoperative infection in patients.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
