DemeTech SK164019F4P DemeSILK, Silk Suture, Synthetic Non-absorbable, DFS-2, 19mm, 3/8 Circle, Reverse Cutting Needle, Black, USP Size 4-0, 18 inches, (45cm)

DemeTECH’s Silk Nonabsorbable Suture is a sterile surgical thread made from fibroin, an organic protein sourced from the domesticated Bombyx mori species. It can be braided and is available with or without attached needles, in various lengths and needle types. This suture complies with all U.S. Pharmacopeia standards for Nonabsorbable Surgical Sutures.

Composition and Origin

• Material: DemeTech’s Silk suture is made from fibroin, an organic protein.
• Source: The raw material for silk is derived from the cocoon produced by the silkworm larva.

Processing and Characteristics

• Natural Waxes and Gums: Before being used for sutures, the natural waxes and gums of silk are removed. This process ensures a tight, compact braid, enhancing the suture’s quality.
• Visibility: The silk suture is dyed black to enhance its visibility during surgical procedures.
• Nature: DemeTech’s Silk suture is non-absorbable and multifilament, which means it is made of multiple threads twisted together.

Tissue Reaction and Durability

• Inflammatory Reaction: Being a natural fiber, silk does initiate an acute inflammatory reaction when placed in tissue.
• Encapsulation: Post the inflammatory response, the suture gets gradually encapsulated by fibrous connective tissue, typically within 14-21 days.
• Tensile Strength: Although classified as non-absorbable, the suture experiences a progressive degradation over time. Most of its tensile strength diminishes within the first year of placement.

Key Points

• Natural Origin: The suture’s base, silk, comes from a natural source, making it distinct from synthetic suture materials.
• Processing: The removal of natural waxes and gums is a critical step in preparing the suture, ensuring its quality and functionality.
• Tissue Response: Being organic, silk sutures do elicit a tissue response, which is a factor to consider during its application.

DemeTechs Silk suture offers a unique blend of natural origin and meticulous processing. While it provides the required support during the initial stages of wound healing, its gradual loss of strength over time makes it suitable for specific surgical applications where long-term tensile strength isn’t a primary concern. Proper understanding and application of this suture can leverage its benefits while mitigating potential tissue reactions.

DemeTech SK164019F4P DemeLENE, Polypropylene Suture Suture Material DemeTechs Silk suture is a non-absorbable, sterile, surgical suture composed of an organic protein called fibroin. DemeTechs silk sutures are processed to remove the natural waxes and gums from its origin. . As Silk is a natural fiber, it does illicit an acute inflammatory reaction, which is followed by gradual encapsulation of the suture by fibrous connective tissue (occurring usually in 14-21 days). While DemeTechs silk sutures are not considered absorbable sutures, progressive degradation of its fibers results in the gradual loss of tensile strength within the first year. – Raw silk is produced by a silkworm larvas cocoon. These natural waxes and gums are removed prior to the braiding process, allowing fora tighter, more compact braid. – DemeTechs Silk suture is dyed black for easier visibility in tissue. – DemeTechs Silk suture is non-absorbable and multifilament in nature. – Although DemeTech classifies its silk suture as a non-absorbable suture, it loses most of its tensile strength in one year

Precautions of DemeTech SK164019F4P DemeLENE Polypropylene Suture

In handling this or any other suture material, care should be taken to avoid damage from handling. Avoid crushing or crimping damage due to application of surgical instruments such as forceps or needle holders. As with any suture material, adequate knot security requires the accepted surgical technique of flat, square ties, with additional throws as warranted by surgical circumstance and the experience of the surgeon. The use of additional throws may be particularly appropriate when knotting monofilaments.
