Description

Technical Field

[0001] The invention belongs to the technical field of medical auxiliary equipment, and in particular relates to a novel vascular anastomosis device. Background Art

[0002] Organ transplantation is a complex operation that transplants a healthy organ into a patient's body. Its purpose is to replace an organ that has lost its function due to disease. With the continuous improvement of organ transplantation surgery technology and the level of perioperative treatment, the survival rate and quality of life of organ transplant patients have been significantly improved. Organ transplantation technology has become a recognized effective means of treating various end-stage organ diseases.

[0003] In liver and kidney transplantation, the most difficult and technically demanding part of implanting new organs after organ removal is the repair and reconstruction of the donor and recipient's internal arteries and veins, which is of decisive significance to the success rate of the operation and postoperative recovery. For example, the recipient side of the superior and inferior vena cava of the liver is difficult to leave long and is easy to retract. The diameter of the blood vessels ranges from 10 to 30 mm, and the existing instruments cannot achieve anastomosis. At present, the common method in the world is still manual continuous eversion suture. Due to the small space, the operation is difficult and time-consuming. The reconstruction of blood vessels takes an average of 35-60 minutes, which makes the liver-free period during the operation long, which has a great impact on the heart, lungs and other organs. In addition, the quality control is affected by the doctor's skills, and complications such as postoperative bleeding and vascular interface stenosis are prone to occur. It is the most critical part of organ transplantation.

[0004] Therefore, it is necessary to provide a novel vascular anastomosis device. Summary of the invention

[0038] The closing mechanism 9 includes a rotating wheel 91, a rotating rod 92, a rotating tooth 93 and a fixed rod 94. The rotating wheel 91 is connected to the rotating tooth 93 through the rotating rod 92. The rotating tooth 93 is connected to the fixed rod 94. The rotating tooth 93 is meshed with the left rotating tooth 82 and the right rotating tooth 83. The fixed rod 94 is installed in cooperation with the first rack 86 and the second rack 87. The ejection mechanism 6 is arranged on the fixed rod 94.

[0039] With such arrangement, the movement process of the device is as follows: by rotating the rotating wheel 91 clockwise, the rotating gear 93 is driven to realize synchronous movement, so that the left rotating gear 82 and the right rotating gear 83 rotate counterclockwise at the same time, and the rotation of the left rotating gear 82 drives the rotation of the gear A84, so that the No. 1 rack 86 produces relative movement toward the fixed rod 94, thereby driving the left base and the left anastomotic ring to move synchronously inwardly, and the rotation of the right rotating gear 83 drives the rotation of the gear B85. Since the No. 1 rack 86 and the No. 2 rack 87 are staggered, the No. 2 rack 87 can also produce relative movement toward the fixed rod 94, driving the right base and the right anastomotic ring to move synchronously inwardly, so that the two anastomotic rings can be fitted together. When the rotating wheel 91 is rotated counterclockwise, the movement principle produced is opposite to that of the clockwise direction, so that the anastomotic rings are separated.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
