The following aspects need to be considered when using nylon threads in medical textiles and surgical instruments:
Biocompatibility: Nylon thread must be biocompatible, meaning it will not react adversely with human tissue, such as inflammation, infection, or rejection. Biocompatibility is an important criterion for medical device material selection because it is directly related to patient safety and comfort.
Mechanical properties: Nylon threads need to be strong and tough enough to withstand the tension and pull during surgery. Its elastic modulus, tensile strength, elongation at break and other mechanical performance indicators should meet the relevant standards of medical devices.
Chemical stability: Nylon thread should have good chemical stability and not be easily eroded or degraded by chemicals in body fluids, disinfectants or other medical supplies. This ensures that the nylon thread maintains its original properties and shape during surgery and use.
Sterility: Medical textiles and surgical instruments need to be used under sterile conditions, so nylon threads should also be easy to clean, disinfect and sterilize. In addition, it should be kept sterile during use to avoid the introduction of bacteria or other microorganisms that could lead to infection.
Operability and processability: Nylon thread should be easy to operate, such as suturing, knotting, etc., to facilitate doctors' surgical operations. At the same time, it should also be easily processed into medical textiles and surgical instruments of different specifications and shapes.
Cost considerations: While performance is a key factor, cost is also a factor that cannot be ignored in the medical field. The cost of nylon thread should be relatively reasonable to meet the purchasing budget of the medical institution and the financial affordability of the patient.
In summary, the use of nylon threads in medical textiles and surgical instruments requires comprehensive consideration of multiple aspects such as biocompatibility, mechanical properties, chemical stability, sterility, operability and processability, and cost. In practical applications, the appropriate nylon thread type should be selected based on specific medical needs and product characteristics. At the same time, medical institutions and manufacturers should also strictly abide by relevant medical device standards and regulations to ensure product quality and safety.
