Problems solved by technology

The problem with this method is that the suture between the artificial blood vessel and the coronary artery is fragile and the blood pressure is high, so the probability of bleeding is high, which is still the main reason for the failure of the aortic root operation and the death of the patient

Embodiment Construction

[0019] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0020] see figure 1 , is a schematic diagram of the valved tube 100 in an embodiment of the present invention. The valved conduit 100 includes an artificial blood vessel 10 and an artificial valve. The artificial blood vessel 10 has a proximal end A and a distal end B. The proximal end A fits the heart, and the distal end B fits the aorta 200 . The artificial valve is located at the proximal end A of the artificial blood vessel 10 .

[0021] A left opening 11 and a right opening 12 are provided on the side wall of the artificial blood vessel 10 close to the artificial valve at the proximal end A. correspond. In this embodiment, the axial distance between the left and right openings and the artificial valve along the artificial blood ves...

Abstract

The invention discloses a valved homograft conduit, which comprises an artificial blood vessel and an artificial valve. The artificial blood vessel is provided with a near end to a heart and a far end to the heart, and the artificial valve is located at the near end to the heart of the artificial blood vessel. A left opening and a right opening are arranged on the lateral wall of the artificial blood vessel at the positions close to the artificial valve, and the positions of the left opening and the right opening correspond to openings of a left coronary artery and a right coronary artery. The valved homograft conduit further comprises a hard homograft conduit which is communicated with the artificial blood vessel and is ligatured with an aorta through a ligation belt, wherein the hard homograft conduit comprises a hard homograft conduit of the near end to the heart, the hard homograft conduit of the near end to the heart is located between the left opening, the right opening and the far end to the heart and is close to the near end to the heart of the artificial blood vessel. A space is formed between the ligation position and an aortic valve, and blood not only is supplied to a whole body along the artificial blood vessel, but also flows into the space through the openings, and further is supplied to the left coronary artery and the right coronary artery. The openings and the coronary arteries are not needed to be sutured, and the bleeding probability of an anastomotic stoma is reduced.

Description

technical field [0001] The invention relates to the field of valve-bearing pipelines, in particular to a valve-bearing pipeline with a hard pipeline. Background technique [0002] The valved conduit is an artificial blood vessel with a valve, and the valved conduit includes an artificial blood vessel and an artificial valve. The use of the valved catheter simplifies the aortic root surgery. The traditional aortic root surgery method is: cut the aorta, remove the diseased valve, and remove the original arterial blood vessel; suture the proximal and distal ends of the artificial blood vessel directly to the heart and On the artery, and directly at the position of the corresponding coronary artery of the artificial blood vessel, it is sutured with the coronary artery. The problem brought about by this method is that the suture of the artificial blood vessel and the coronary artery is fragile and the blood pressure is high, so the probability of bleeding is high, which is still...
