Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The invention can also be implemented or applied in other different embodiments, and without conflict, the features in the following embodiments and examples can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The improved artificial blood vessel shown in fig. 1 comprises a blood vessel main body, wherein two ends of the blood vessel main body are respectively provided with a traction part, and the blood vessel main body is fixedly connected with the traction parts; a plurality of suture parts are arranged on the side wall of the blood vessel main body; the number of the sewing parts is A, and A is more than or equal to 2.

When the artificial blood vessel is implanted, the position of the artificial blood vessel is adjusted by clamping the traction part 2 by using forceps or tweezers, so that the sharp instruments are prevented from damaging the blood vessel main body 1; when shaping, sew up portion 3 and artificial blood vessel surrounding tissue with sewing up, avoid blood vessel main part 1 to receive the damage.

As shown in fig. 1 to 3, the blood vessel body 1 has a circular tubular structure, and is implanted into a patient to transmit blood to the patient instead of a diseased blood vessel, to transport oxygen and nutrients to a tissue near an artificial blood vessel placement site, and to discharge carbon dioxide and metabolites.

Specifically, the distance between the adjacent sewing parts 3 is 10-20mm; the distance between the traction part 2 and the stitching part 3 is 10-20mm. The smaller the distance between the suture parts 3 and the distance between the traction part 2 and the suture parts 3, the smaller the difference between the shape of the formed blood vessel and the shape of the original blood vessel, and the better the requirement of the patient can be met.

As shown in fig. 1-3, the traction portion 2 has a circular ring-shaped structure. The outer diameter of the traction part 2 is larger than the outer diameter of the vessel body 1. The two traction parts 2 are respectively arranged at two ends of the blood vessel body 1, and the outer sides of the traction parts 2 protrude out of the blood vessel body 1 so as to be convenient for being clamped by a pair of forceps or tweezers. In the process of drawing the artificial blood vessel, after the artificial blood vessel reaches the designated position, the drawing part 2 can be sutured with the tissue near the blood vessel main body 1 to shape the artificial blood vessel. Preferably, the traction part 2 can be cut according to the condition of the tissue near the blood vessel body 1 during shaping, so that the artificial blood vessel can be more fit to the patient.

As shown in fig. 1 to 3, the sewn portion 3 has a circular ring-shaped structure. The inner diameter of the suturing part 3 is equal to the outer diameter of the vessel body 1. The suture part 3 is firmly fixed on the outer side wall of the vessel body 1. The suture part 3 has an outer diameter larger than that of the blood vessel body 1. In the process of drawing the artificial blood vessel, forceps or tweezers can be used for clamping the suture part 3 and drawing the artificial blood vessel to a proper position. The suture part 3 is sewed with the surrounding tissues during the molding, so that the defect that the artificial blood vessel needs to be punctured during the molding of the artificial blood vessel is avoided. Preferably, the suture part 3 can be cut according to the condition of the tissue near the blood vessel body 1 during shaping, so that the artificial blood vessel can be more fit to the patient.

The outer diameter of the suture part 3 is equal to the outer diameter of the traction part 2. The whole structure is uniform and convenient for packaging and transportation.

Alternatively, the outer diameter of the suture part 3 is smaller than the outer diameter of the traction part 2. In the traction process, a doctor can conveniently use forceps or tweezers to clamp the traction part 2, the possibility of mistakenly clamping the suture part 3 is reduced, the artificial blood vessel is deviated, and the operation time is prolonged.

Alternatively, the outer diameter of the suture part 3 is larger than the outer diameter of the traction part 2. Sufficient space is provided for artificial blood vessel shaping suture, and the larger suture part 3 can receive more times of suture puncture, so that the connection between the artificial blood vessel and surrounding tissues is tighter.

The application method of the embodiment comprises the following steps:

1. clamping the traction part 2 by using a pair of pliers or tweezers, drawing the artificial blood vessel to a proper position, and adjusting the shape of the artificial blood vessel;

2. the suture part 3 is sutured with the surrounding tissue to shape the artificial blood vessel.

Preferably, the suture part 3 can be held by forceps or tweezers during the traction process to adjust the shape of the artificial blood vessel; the traction part 2 can be sutured with the surrounding tissues in the shaping process, and the shape of the artificial blood vessel is more suitable for the condition of a patient.
