Manufacturing process and application of medical absorbable cattle intestine suture line

Abstract

The invention discloses a manufacturing process of a medical absorbable cattle intestine suture line. The manufacturing process comprises the following production steps of material selection, degreasing, primary washing, secondary washing, thread twisting, airing, polishing, sterilization and packaging. The collagen content of the medical absorbable cattle intestine suture line reaches 95%, the tensile strength of sutures of various models meets the industrial standard requirement, the suture body is free of muscular tissue attachment and chemical component residues, the suture line is good in biocompatibility, the suture line can be effectively degraded and absorbed after body suture, the original physical and mechanical properties of the suture line material are kept, and the clinical use safety of the product is ensured; the postoperative suture is good in tissue compatibility and free of organism exclusion; the composition can be completely degraded and absorbed without forming scars; and after the operation, calcification and subcutaneous induration are avoided, and the carrying breaking strength and the knotting breaking strength of the suture line are high in the suture process.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a manufacturing process of a medical absorbable bovine intestine suture and its application. Background technique [0002] Medical thread (Suture) refers to the thread used to suture traumatic wounds or damaged parts of the human body due to surgery. Nylon and silk, synthetic polymer materials with high physical properties, and alternative materials were developed and widely used in the early days of medical threads, but these materials are not decomposable and physiologically compatible in the human body, so after a predetermined period of time after surgery It should be removed through additional surgery, which is inconvenient to use, so the use is limited. In addition, the breaking strength and knot breaking strength of absorbable sutures on the market are relatively low. [0003] Aiming at the problems in the related technologies, no effective solution ha...
