Gastrointestinal surgical operation suture line and manufacturing method thereof

Abstract

The invention provides a gastrointestinal surgical operation suture line and a manufacturing method thereof. The operation suture line is composed of three layers, wherein the innermost layer is an alloy core material, the second layer is a biopolymer layer, the third layer is a collagen layer, the thickness ratio of the biopolymer layer to the collagen layer is (1-1.5): (2-2.5), the alloy core material is linear, the diameter of the alloy core material is 40-80 micrometers, the surface of the alloy core material is wound with a sheep intestine layer and the collagen layer, the alloy core material is made of zinc-magnesium alloy, and the collagen layer is made of the backbone part striated muscle tendon of a mampalon. Preparation of the alloy core material comprises the steps of adding 5-10 g of magnesium oxide, 1-4 g of soya bean lecithin and 2-6 g of citric acid into a reaction container where 20wt% of KOH solution is stored, and then sequentially carrying out heating, heat preservation and filtering on the mixture, and drying the obtained solid after filtering to obtain the final product. The gastrointestinal surgical operation suture line has high antibacterial performance, theprobability of inducing wound infection is greatly reduced, wound healing is fast, strength is high, and the operation suture line is not prone to breakage.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a surgical suture for gastrointestinal surgery and a manufacturing method thereof. Background technique [0002] Operations in gastrointestinal surgery are very common. After the operation, the patient's wound site needs to be sutured to speed up wound healing and avoid infection. Therefore, surgical sutures are needed when suturing. Surgical sutures are a kind of The thread material for surgical sutures, due to the particularity of the field of gastrointestinal surgery, the surgical sutures need to meet the following characteristics: it can maintain sufficient strength during the wound healing process, and it should be able to elongate to adapt to wound edema and return with the wound. Shrink and retract to the original length; after the wound is healed, it can degrade and absorb itself, leaving no foreign matter; no inflammation; non-irritating and carcinogenic; eas...

Problems solved by technology

[0002] Operations in gastrointestinal surgery are very common. After the operation, the patient's wound site needs to be sutured to speed up wound healing and avoid infection. Therefore, surgical sutures are needed when suturing. Surgical sutures are a kind of The thread material for surgical sutures, due to the particularity of the field of gastrointestinal surgery, the surgical sutures need to meet the following characteristics: it can maintain sufficient strength during the wound healing process, and it should be able to elongate to adapt to wound edema and return with the wound. Shrink and retract to the original length; after the wound is healed, it can degrade and absorb itself, leaving no foreign matter; no inflammation; non-irritating and carcinogenic; easy to dye, sterilize, disinfect and other treatments; can form a safe and firm However, the sutures in the prior art often cause inflammatory reactions, related diseases, etc. in patients due to poor immunogenicity elimination and poor virus inactivation effects, etc., so it is necessary to provide a new gastrointestinal surgery A surgical suture and a manufacturing method thereof, thereby obtaining a surgical suture with good strength and high safety
