Embodiment Construction

[0052] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.

[0053] like figure 1 As shown, the embodiment of the present invention provides a valved conduit, which includes:

[0054] the duct wall 101 and the valve structure 102;

[0055] The valve structure 102 is sutured on the pipeline wall 101 to form at least two valve pockets 103;

[0056] The first edge of the duct wall 101 and the second edge of the d...

Abstract

The invention provides a valve pipe and a preparation method thereof. The valve pipe comprises a pipe wall and a valve structure. At least two valve pocket are formed by suture that valve structure onthe pipe wall; The first edge of the duct wall and the second edge of the duct wall are stitched together by stitching one knot per needle to form a duct cavity; at least two pocket are located in that lumen of the conduit, and the at least two pocket overlap each other. Therefore, the scheme provided by the invention can reduce the probability of the valve pipe opening when trimming the valve pipe.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a valve-carrying pipeline and a preparation method thereof. Background technique [0002] Valved conduits are artificial blood vessels with artificial valves that can be implanted in the body to replace diseased blood vessels. [0003] Currently, valved tubes are often used to replace diseased blood vessels in patients with heart disease. During the operation, in order to suture the valved conduit accurately, the doctor needs to trim the wall of the valved conduit so that the length and shape of the valved conduit can meet the connection requirements. However, when trimming a valved duct, there is a high probability that the sutures used to suture the valved duct will be open. Contents of the invention [0004] The embodiments of the present invention provide a valved pipeline and a preparation method thereof, which can reduce the probability of opening of the valved ...
