What is a surgical suture?

A surgical suture is an essential medical tool used to bring together and hold the body's tissues after surgery or injury. Sutures allow for optimal wound healing by carefully aligning the wound edges, minimizing the risk of infection, and promoting speedy recovery.
Surgical sutures can be made from various materials, such as silk, catgut, polyester, nylon, or biodegradable synthetic polymers, each with specific properties of elasticity, tensile strength, durability, and tissue reactivity. There are also different types of sutures, including resorbable (absorbed by the body over time) and non-resorbable (requiring removal after healing), as well as monofilament (single strand) or multifilament (multiple strands braided together) to meet diverse clinical requirements.
Sutures are often attached to a specific needle designed to penetrate the tissue with minimal trauma. The appropriate selection of suture material and needle depends on various factors, including the type of surgery, the nature and location of the wound, and individual patient characteristics.

History and Evolution of Surgical Sutures

Surgical sutures are an ancient medical instrument dating back to ancient Egypt, where linen and hemp threads were used to suture wounds. Over the centuries, various materials have been used, such as silk, catgut (made from animal intestines), and even human hair. In the 19th century, the introduction of the curved needle significantly improved the efficiency of sutures. However, the evolution of surgical sutures truly took place with the advent of modern surgery.
With the advancements in medical technology in the 20th century, surgical sutures underwent significant evolution. Sterilization, first through heat and later through radiation, greatly reduced the risk of infection. Sutures became thinner, stronger, and safer with the use of synthetic materials such as nylon, polyester, and polypropylene. More recently, innovation has led to the creation of resorbable sutures, which naturally degrade within the body, eliminating the need for removal.
Today, research continues, with the development of "smart" sutures that can release drugs or signal signs of infection. In our marketplace, we strive to offer you the latest advancements in surgical sutures, helping you provide the best possible care to your patients.

What are the different types of surgical sutures?

In this section, we will provide an overview of the different categories of surgical sutures available in the medical market.

Resorbable vs Non-resorbable

Resorbable sutures are designed to degrade and be absorbed by the body over time. They are often used for internal sutures where removal would be difficult or traumatic. Non-resorbable sutures, on the other hand, do not degrade and need to be removed once the wound has sufficiently healed.

Monofilament vs Multifilament

Monofilament sutures are composed of a single strand, providing a smooth surface that easily passes through tissues with minimal trauma. Multifilament sutures are made up of several strands braided together, offering greater flexibility and tensile strength, but they may be more prone to tissue reactions.

Synthetic vs Natural

Synthetic sutures, such as nylon or polypropylene, are designed to minimize tissue reactions and provide consistent tensile strength. Natural sutures, like silk or catgut, are typically more pliable and easy to handle but may induce a more pronounced tissue reaction.

Suture specific to certain types of surgery

Some sutures are specifically designed for certain types of surgery, such as cardiovascular surgery, plastic surgery, ophthalmic surgery, or dental surgery. These sutures have specific characteristics, such as tensile strength, flexibility, or resorption time, that make them particularly suitable for these purposes.

How to choose the right suture material?

Choosing the right suture material depends on several factors. Tensile strength is crucial to ensure stability during the healing process. Capillarity, or the ability to absorb bodily fluids, should be minimized to prevent infection. Ease of handling directly impacts the surgeon's efficiency and the patient's comfort. Lastly, tissue reactivity, or the body's response to the suture material, should be minimal to promote quick and complication-free healing.

The importance of needle size and configuration

The size and configuration of the needle are also critical factors. A well-chosen needle minimizes tissue trauma during suture placement. Its shape, diameter, and tip should be adapted to the texture and thickness of the tissue being sutured. Additionally, the size of the suture material should be proportional to the tissue thickness: thicker tissue requires a stronger suture.

Specific criteria for each type of surgery and wound

Each surgical procedure and wound type have specific suture requirements. For example, high-risk infection wounds require non-capillary sutures, while aesthetic skin closures benefit from thin monofilament sutures and small needles. Additionally, certain surgeries, such as cardiovascular or ophthalmic surgery, require specific suture materials.
