[Prior art]

 At present, the main artery and the artificial blood vessel (Artificial Vessels) are joined in the surgical treatment of the main aneurysm and the main artery detachment, and the traditional artificial blood vessel (A) is designed by a Dacron steel thread having elasticity and elasticity. The necessary portion of the artificial blood vessel (A) is cut out, and the suture is connected to the main artery by a direct suture (see FIG. 1). The disadvantage of this method is that the main artery itself is very fragile and susceptible to tearing due to its own lesions, so it is extremely prone to re-cracking or dropping at the suture connection. In addition, because of the suturing method using a suture line, the operation takes a long time, which causes a large amount of bleeding from the main artery, which often affects the effectiveness of emergency rescue treatment. For this reason, a second method occurs (see FIG. 2). In this method, a binding hard ring (A1) is installed in the artificial blood vessel (A), and a binding hard ring (A1) at one end of the artificial blood vessel (A). Is fixed beforehand (or both ends are fixed), and the binding hard ring (A1) at the other end is activated (see Fig. 2). After the adjustment, the movable bundling hard ring (A1) is sutured and fixed, the bundling hard ring (A1) is put on the arterial blood vessel, and the bundling thread is further tightened and fixed with the bundling thread. Connect. This method has a time-saving effect compared to the former.

[0003] However, the design of the binding hard ring (A1) is placed outside the artificial blood vessel, and the inner layer of the material of the binding hard ring (A1) is made of plastic. It was necessary to cover the outer surface with an artificial felt fiber having a more flexible structure, and then suture and fix the hard ring to both ends of the artificial blood vessel with a suture. After the hard ring was coated with this artificial felt fiber, its thickness naturally increased, resulting in a large difference between the outer diameter of the human vessel and the inner diameter of the artificial blood vessel, which was one serious drawback. In addition, the flexible felt structure outside the hard ring cannot prevent blood from penetrating, so blood bleeds at the suturing part or the tying part, so that heparin protamine is administered to the sick. Without it the bleeding could not be stopped. Thus, it had the drawback of its structure.

[Problems to be solved by the invention]

 The present invention has been made in view of the above-mentioned drawbacks of the prior art, and provides a kind of artificial blood vessel connecting sleeve ring structure which solves the drawbacks. It shall have the following advantages: 1. The sleeve ring is fitted into the inside diameter of the artificial blood vessel, directing the artificial blood vessel for preventing blood bleeding and the inner wall of the main artery, and has no blood bleeding or blood leakage. 2. It has a thin-walled design, does not occupy the space between the blood vessel walls, and reduces the difference in inner diameter when connecting the main artery to the artificial blood vessel. 3. Immediately connect the vascular prosthesis to the main artery, reducing the operation time and bleeding volume 4. Reduces bleeding at the junction. 5. The sleeve ring material is made of a highly biocompatible metal (in the preferred embodiment of the present invention titanium is used). 6. Manufactured to different tube diameter standards and used during surgery can be used.

[Embodiment of the invention]

 In the sleeve ring structure of the present invention, the same parts are denoted by the same reference numerals in different drawings. The present invention provides a kind of artificial blood vessel connecting sleeve ring structure, which is composed of a sleeve ring 1, a binding thread 2, an artificial blood vessel (A), and a human blood vessel (B). Please refer to FIGS.

The sleeve ring 1 has a penetrating ring shape, is formed of a biocompatible material, has an inner wall 11 formed therein, a small ring groove 12 and a large ring groove 13 formed outside, and a binding thread. 2 is compatible with the human body, but is considered non-absorbable.

The sleeve ring 1 is first inserted into the artificial blood vessel (A), and the artificial blood vessel is tied and positioned at the position of the small annular groove 12 with the relatively thin binding yarn 2. Further, the cut portion of the human blood vessel (B) is inserted into the artificial blood vessel (A), and the outside of the human blood vessel is tied and positioned at the position of the large annular groove 13 with the relatively thick tying thread 2, thus quickly and easily. The connection between the artificial blood vessel (A) and the human blood vessel (B) is achieved, the two binding portions are mutually complex, and a non-absorbable suture is used for the binding thread 2 of the small annulus groove 12. Previously, it is first passed through the corresponding position of the artificial blood vessel, so that at the time of connection, the small annular groove portion can be directly bound (see the embodiment of FIG. 5).

At the time of implementation, an unabsorbed suture is passed through the hole 14 in advance to sew the artificial blood vessel (A) and the human blood vessel (B), further cover the artificial blood vessel (A), The groove 13 is bound, and the fixation and connection are completed. This is as shown in FIG. FIG. 8 is a display diagram after connection of the present invention and a human body blood vessel (B).

The binding using the binding thread 2 is reliable and can save time as compared with the suture method. In addition, the sleeve ring 1 is joined to both ends of the artificial blood vessel (A) to save the time for blood vessel connection. And the distance between the inner and outer walls of the vessel can be reduced. Therefore, the present invention certainly has the following advantages. 1. A sleeve ring is placed inside the artificial blood vessel to make the inner diameter of the artificial blood vessel compatible with the outer tube of the main artery. 2. The present invention is made of, for example, titanium or other biocompatible materials, is very strong, can adopt a thin wall structure, and does not occupy the vessel wall space. 3. Saves time during surgery. 4. Since a blood-impermeable artificial blood vessel is used between the titanium ring and the blood vessel, and the bundling method is used, and there is no suture-type pore, the amount of bleeding at the joint can be reduced. 5. Many different standards can be formed in advance, which is convenient for use during surgery.
