The Explore And Finishing Properties Of Polypropylene Monofilament Warp (Hernia) Repair Mesh Process

General surgery hernia is a common disease and frequently-occurring disease. Hernia which is prominent in patients with body tissues or organs due to membrane breakage is an important part of basic surgical technical education and has been caught the attention of general surgery doctors for long time. In North American and European countries, epidemiological statistics found the incidence of inguinal hernia of 0.1% ~ 0.5% and the incidence of abdominal wall hernia rate of 2% ~ 10%. Tension of conventional surgery to have surgery, will damage the Organization Depar tment direct suture. In the middle of 1990s, the United States and some Western developed countries, through the use of the methods for the repair mesh hernia surgery without tension, has achieved the rapid development and dominant position in the world. Since 1996, tension-free hernia surgery in China has been gradually adopted by a number of medium and large urban hospitals. Unfortunately, its penetration is far lower than that from United States and Western countries. It is due to the slow updated primary hospital medical technology. The other reason is that the hospitals depend on imports with the high price.Based on this reason, it is urgent to develop the independent intellectual property rights in China and the economic conditions for the majority of patients with hernia repair network that can be accepted imminent. Previously, although someone else has already made some ground-breaking pilot, and has made some valuable sexual experience. However, the samples obtained, are only able to meet the small volume of production in the laboratory and cannot achieve the commercial mass production, and the fabric surface morphology and the main properties of similar foreign products also have a certain gap, so we need to further improve and optimize the pilot programs.First, this paper started from the selection of raw materials to start, through access to information as well as with foreign comparative analysis of similar samples, and selected a set of medical grade polypropylene textile material as in this test material. For the design of the organizational structure, the subjects also used the aforementioned exploratory papers three needle forging organization. However, analysis of this topic found in the practical requirements of clinical hernia repair mesh surface is relatively smooth and easy to make human tissue growth in their surface adhesion shortcoming. Therefore, this paper proceeds from reality, the use of composite needle knitting samples, the surface mesh to repair a more definite bump phenomenon, making it more conducive to human tissue in hernia repair mesh attached to the surface more quickly to promote wound healing.In addition, previous data has shown pairs of mesh hernia repair is only carried out a preliminary analysis of heat-setting trial, but from the practical consideration of mass production, when the fabric under the machine after a natural curl due to the fabric, the fabric must be formed first processing, for processing the next cut, and then for setting treatment, making repair mesh to meet the clinical requirements necessary stiffness and so on. In this way, the two heat-setting the actual large-scale production has become an essential part of the deal, so the two heat-setting process conditions to optimize the design became the subject of another study of this core and innovation points.In the orthogonal basis, by changing the fabric heat-setting process parameters, we analyze heat setting and finishing on the patch network performance impact. Based on the clinical use of tension-free mesh hernia repair of the main physical properties of targets, we select a reasonable experimental parameters factor to the basic physical properties of the target to meet or exceed the standards of similar foreign products developed internally to meet the conditions for large-scale production Tension-free hernia repair mesh repair surgery. Through the research projects, for the introduction of new materials, new processes, new structures, new finishing tension-free hernia repair network research and development, particularly in mass production, we can provide strong theoretical support and a solid experimental basis.Experiments show that by using orthogonal experimental design and the optimal choice derived from the two heat-setting parameters of the prepared finishing tension-free hernia repair network, its basic physical performance indicators are in line with the clinical requirements, and achieve the standards of similar products from abroad.
