I. Core Functions
Medical sutures are the cornerstone materials in surgical procedures for closing wounds, connecting tissues, and promoting healing. Their core functions include:
1. Mechanical Support: Providing precise and sustained tension to stabilize and align incised or damaged tissues, creating a foundation for cell regeneration.
2. Healing Guidance: Acting as a scaffold for tissue growth, guiding cells to grow in an orderly manner, promoting functional healing, and reducing irregular scarring.
3. Biocompatibility and Isolation: As a material acceptable to the human body, it effectively isolates external contamination, reduces the risk of infection, and provides a carrier for local delivery of drugs (such as antibacterial agents).
II. Classification and Significant Advantages
Modern sutures are classified into two main categories based on their absorbability, each with unique advantages:
1. Absorbable Sutures
Materials: Natural (such as catgut, collagen) or synthetic polymers (such as polyglycolic acid (PGA), polylactic acid (PLA), polydioxanone (PDO)).
Advantages:
Convenient, no suture removal required: After the wound gains sufficient strength (usually several weeks to months), it is absorbed and metabolized by the body through hydrolysis or enzymatic degradation, greatly improving patient comfort and reducing the burden of follow-up visits.
Controllable tissue reaction: Especially synthetic absorbable sutures, which have a stable and predictable degradation rate, and the inflammatory response is far lower than traditional catgut sutures.
Dynamic healing matching: Its tension decay curve can match the healing strength growth curve of specific tissues (such as fascia, subcutaneous tissue).
2. Non-absorbable Sutures
Materials: Natural (silk, cotton) or synthetic (polypropylene, polyester, nylon, stainless steel wire).
Advantages:
Permanent support: Provides long-term or permanent mechanical strength, suitable for tissues that heal slowly or require permanent support, such as heart valves, vascular anastomosis, tendon repair, and fixation of certain plastic surgery implants.
Ultimate strength and durability: For example, polypropylene sutures are known for their excellent tensile strength and extremely low tissue reaction, and are widely used in cardiovascular and hernia repair surgeries.
Excellent handling characteristics: For example, silk sutures are safe and secure for knotting, and have a soft feel, making them highly trusted by surgeons. Common Technological Innovation Advantages:
Antibacterial Coating: Such as Vicryl sutures containing triclosan (TC), which can significantly reduce the risk of surgical site infection (SSI).
Structural Optimization: Monofilament sutures are smooth and less likely to harbor bacteria; braided sutures are soft and easy to knot. Barbed sutures eliminate the need for knots, distribute tension evenly, and shorten surgical time.
Integrated Needle and Suture: High-precision manufacturing of the needle-suture connection ensures high strength and smooth passage through tissue, reducing tissue drag and damage.
III. Main Application Scenarios
General Surgery/Gastrointestinal Surgery: Absorbable sutures are used for fascial closure and intestinal anastomosis; non-absorbable sutures are used for abdominal wall hernia repair.
Plastic/Cosmetic Surgery: Extremely fine monofilament nylon or polypropylene sutures are used for intradermal cosmetic suturing; PDO sutures are used for minimally invasive facial lifting.
Cardiothoracic Surgery/Vascular Surgery: Polypropylene sutures are used for vascular anastomosis and cardiac valve replacement fixation.
