Problems solved by technology

The traditional fixation operation is to clean the collected and pruned blood vessels with clean water, normal saline, and balanced salt solution, and then put them directly into the fixative solution for fixation. This method cannot ensure that the valved pipeline is fully fixed, and at the same time, it cannot ensure that the valved pipeline is fully fixed. The original shape is not conducive to the anastomosis of the operation, the quality of the product cannot be guaranteed, and it brings risks to the lives of patients

Embodiment Construction

[0017] In order to further understand the content of the invention, features and effects of this patent, the following examples are exemplified and described in detail as follows:

[0018] 1. Select cattle source: cattle aged 2 to 5 years old, healthy (appearance cattle capillary, uniform, shiny), no infectious diseases and slaughtered cattle, the best breed is captive buffalo.

[0019] 2. Collection of blood vessels: Use a knife to cut the fat layer of the cow's neck and find the jugular vein blood vessels. Grab the blood vessels and use a knife to draw the blood vessels to the heart. Try to cut off the longer part without hurting the blood vessel wall. During the extraction process The blood vessels should be prevented from contaminating the blood vessels with substances such as fibers that are not easily removed in the subsequent process, and the removed blood vessels should be transferred to cleaning within 1 minute.

[0020] 3. Cleaning: Rinse repeatedly with clean water ...

Abstract

The invention relates to an improved method for manufacturing a medical bovine jugular vein valved conduit. The bovine jugular vein valved conduit needs to be fixed before being implanted into human body. A fixing treatment method is improved. The method is characterized in that during fixing, a tube cavity is fully filled with fixing liquid, and the conduit is soaked into a container containing the fixing liquid after the two tail ends of blood vessel are ligated. The method has the advantages that the valved conduit can be fixed fully to better enhance the tissue strength and durability; moreover, the original shape of blood vessel can be well kept, wrinkling, twisting and knotting are avoided, convenience is brought to anastomosis in surgeries, pain of a patient and trouble of an operator are reduced, the surgical risk is lowered, and the use safety is improved.

Description

technical field [0001] The patent belongs to the technical field of manufacturing using medical biological materials, and in particular relates to a manufacturing method of a bovine jugular vein valved pipeline. Background technique [0002] The incidence of congenital heart disease ranks first in birth defects. About 1 / 3 of patients with congenital heart disease have different degrees of right ventricular or left ventricular outflow tract obstruction, and a considerable part of them need to use valved conduit or valved vascular sheet to reconstruct the right ventricular outflow tract to achieve radical cure, such as Fallot quadruple Severe pulmonary artery stenosis, pulmonary atresia or common arterial trunk in transposition of great vessels, etc. Commonly used materials include artificially synthesized xenogeneic valved conduits, allogeneic aortic valved conduits, and allogeneic valved conduits, but these materials all have limitations, such as the easy calcification of h...
