Manufacturing method of microscopic suture material for practice

Abstract

The invention belongs to the technical field of microscopic suture materials, and discloses a manufacturing method of a microscopic suture material for practice, the manufacturing method comprises thefollowing steps: S1, taking out swimming bladders from live fish; S2, removing attachments on the swimming bladders, and cleaning the swimming bladders; S3, storing the treated swimming bladders in normal saline or a refrigerator; S4, performing cross-linking treatment on the swimming bladders by using a disinfectant; and S5, preparing materials for practicing microscopic suture. The swimming bladders treated by the preparation method disclosed by the invention still have the advantages of being good in flexibility, high in tensile strength and of a double-layer structure, and due to the factthat swimming bladder tissues are similar to human dura mater tissues, tissues such as dura mater and anastomotic blood vessels of a person can be stitched in an operation in a simulated mode, the swimming bladders can serve as a good practice material for doctors or medical students, and great help is provided for improving operation skills.

Description

technical field [0001] The invention relates to the technical field of micro suture materials, in particular to a method for making micro suture materials for practice. Background technique [0002] At present, the materials available for microsuturing practice mainly fall into the following three categories: [0003] (1) Basic materials: gauze, leaves, hose, rubber, etc.; [0004] (2) Simulation materials: quasi-vascular static objects such as chicken wings and placenta; [0005] (3) Model materials: living animals with true blood vessels such as rats and mice; [0006] The above three types of materials have their own advantages and disadvantages. The advantage of basic materials is that they are easy to obtain and can be used for practice at any time, but the disadvantage is that their simulation performance is poor. The advantage of simulation materials is that their simulation performance is better than that of basic materials, but they are not easy to obtain. It is ...

[0006] The above three types of materials have their own advantages and disadvantages. The advantage of basic materials is that they are easy to obtain and can be used for practice at any time, but the disadvantage is that their simulation performance is poor. The advantage of simulation materials is that their simulation performance is better than that of basic materials, but they are not easy to obtain. It is not easy to preserve for a long time; the advantage of model materials is that they are closest to human tissue, but the disadvantage is that they are not easy to obtain and cannot be used for practice anytime and anywhere

[0007] Swim bladder is a new material for micro suture practice, but it is difficult to preserve, and it is inconvenient to use when frozen; it is easy to denature and spoil when soaked in saline; soaked in 75% alcohol, its texture becomes hard and loses its flexibility
