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 given hereby, and the details are as follows:

[0018] 1. Select the source of cattle: Cattle aged 2 to 5 years old, healthy (the appearance of cattle capillary, uniform and shiny), without infectious diseases, the best breed is captive buffalo.

[0019] 2. Collect blood vessels: use a knife to cut the fat layer of the neck of the cow and find the jugular vein, grab the blood vessel and use the knife to draw along the blood vessel to the heart, try to cut as long as possible without hurting the vessel wall, during the extraction process Contamination of blood vessels by substances such as fibers that are not easily removed in subsequent procedures should be avoided, and the removed blood vessels should be transferred for cleaning within 1 minute.

[0020] 3. Cleaning: Rinse repeatedly with clean water (without any visible impurities) to remove blo...

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] This patent belongs to the technical field of manufacturing using medical biomaterials, and in particular relates to a method for manufacturing 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 a valved catheter or a valved blood vessel piece to reconstruct the right ventricular outflow tract in order to obtain a radical cure, such as Fara quadruple syndrome, right ventricular double outlet, severe pulmonary stenosis in transposition of the great vessels, pulmonary atresia, or common truncus. Commonly used materials include synthetic heterogeneous valve-bearing conduits, allogeneic aortic valve-bearing conduits, and homogeneous valve-bearing conduits, but these materials all hav...
