Abstract

The invention discloses a blood vessel protection belt and a preparation method and application thereof. The blood vessel protection belt is coiled by a long-strip-shaped collagen thin film or a long-strip-shaped collagen composite thin film. The blood vessel protection belt is applied to isolation of blood vessels and tissue liquid, the blood vessels are subjected to skeletonization dissection, and the tissue liquid is abdominal pus or digestive juice after radical excision surgery of hepatic-biliary-pancreatic malignant tumors. For the first time, it is proposed that the strip-shaped collagen film and the strip-shaped collagen composite film are used as the blood vessel protection belt, and the blood vessel protection belt is used for the radical excision surgery of gastrointestinal tumors, especially the hepatic-biliary-pancreatic malignant tumors, is wound around the arteriovenous blood vessels subjected to skeletonization lymphatic tissue dissection, conducts isolation protectionon the blood vessels, and prevents the abdominal pus or the digestive juice leaking from anastomotic stoma from corroding the blood vessels and then causing hemorrhage.

Description

technical field

[0001] The invention relates to a medical device, in particular to a blood vessel protection band and its preparation method and application. Background technique

[0002] Collagen is the most abundant and widely distributed protein in animals. It is the main structural protein of the body and the main component of tissue and connective tissue. The amino acid chain structure of collagen's unique three-strand peptide chain helix results in its many useful properties, such as high tensile strength, biodegradability, low antigenicity, low stimulation and low cell activity, and cell growth-promoting properties. All these characteristics endow it with high biosafety and bioavailability, and also make it an ideal biomedical material.

[0003] Collagen has a wide range of clinical applications. It has been confirmed that it can promote wound healing and the growth of granulation tissue. It has good hemostatic function, filling function and biological scaffold. The...
