Ethicon Johnson - NW5052P - Mersilk Sutures USP 2-0, 1/2 Circle Reverse Cutting - NW5052 - 12 Foils Box

This product is a non-absorbable surgical suture designed for use in various surgical procedures. The suture material is braided silk, derived from the cocoons of the silk worm Bombyx Mori. It is dyed black for enhanced visibility during surgical manipulation.

The suture is coated with beeswax, which aids in handling and knot security. The material is constructed to provide prolonged retention of tensile strength, maintaining its integrity for approximately three months post-implantation. This characteristic makes it suitable for tissues that require extended support during the healing process.

The suture is supplied pre-attached to a 50 mm, 1/2 circle reverse cutting needle. The needle is crafted from SS 420 alloy, known for its strength and sharpness, and is silver in color. The reverse cutting needle design facilitates easier passage through tough tissues and reduces the risk of tissue cut-through, making it particularly effective for skin closure and other dense tissue applications.

Each box contains 12 individually foil-packaged sterile units. The sterilization method employed is radiation, ensuring product safety and efficacy. The suture diameter conforms to USP 2-0 standards, indicating a specific gauge suitable for various surgical needs.

The suture length is 76 cm, providing adequate material for multiple throws and secure knot tying. This suture is intended for use by trained medical professionals in sterile surgical environments. Its non-absorbable nature means it will remain in the tissue indefinitely unless intentionally removed, making it appropriate for applications where long-term tissue support is required.

The combination of braided silk, beeswax coating, and a robust reverse cutting needle makes this suture a reliable choice for precise and secure wound closure. The product is supplied in a box containing 12 individual sterile foils, each with a pre-attached needle and suture. The braided construction offers good tensile strength and pliability, while the silk material is known for its excellent handling characteristics and knotting properties.

The reverse cutting needle geometry is designed to penetrate tough tissues with less force and to minimize the risk of tearing the tissue edges, which is advantageous in procedures involving skin and other fibrous tissues. The 50mm needle length and 1/2 circle curvature are standard dimensions that facilitate ease of manipulation within surgical fields. The 76cm suture length offers sufficient material for surgeons to perform multiple knot throws, ensuring secure wound closure.

The black dye enhances visibility against the surgical field, aiding in accurate placement and knotting. The non-absorbable nature of silk makes it suitable for long-term wound support, such as in skin closures that may require extended healing time or in situations where permanent support is desired. The beeswax coating contributes to a smoother passage through tissue and improved knot security, reducing the likelihood of slippage.

The product is sterilized using radiation, a common and effective method for medical devices, ensuring sterility upon opening. The USP 2-0 size is a mid-range diameter, suitable for a broad spectrum of surgical applications where a balance of strength and tissue trauma is considered. The 1/2 circle needle is a versatile shape that allows for easy manipulation in confined spaces and for a variety of suturing techniques.

The reverse cutting edge is particularly beneficial for dense tissues like skin, fascia, and tendons, as it presents a sharp edge that cuts through the tissue while the cutting edge is oriented away from the wound, reducing the risk of tissue damage. The prolonged tensile strength retention is a key benefit for applications requiring sustained wound support over several weeks. The braided construction provides a high degree of flexibility and knot security, which are critical factors in successful wound closure.

The natural origin of silk, combined with modern processing and sterilization techniques, results in a suture that is both effective and well-tolerated in many surgical settings. The individual foil packaging ensures that each suture-needle combination remains sterile until the point of use, minimizing the risk of contamination and ensuring product integrity. The product is designed for single use only, adhering to standard medical practice for surgical consumables.

The combination of material properties, needle design, and packaging makes this a comprehensive option for surgical wound closure. The use of SS 420 stainless steel for the needle ensures durability and sharpness throughout the procedure. The 50mm needle length is a common size that offers a good balance between maneuverability and bite acquisition in various anatomical locations.

The 1/2 circle curvature is well-suited for superficial closures and for suturing in areas with limited access. The reverse cutting needle is a specialized design that offers superior penetration in tough tissues compared to conventional cutting needles, while the triangular point is oriented away from the wound edge to minimize tissue trauma. The braided silk suture, with its natural origin and excellent handling characteristics, provides a secure and reliable closure.

The beeswax coating further enhances its usability by providing a smooth passage through tissues and improving knot security, reducing the need for excessive knot tying. The non-absorbable nature of the suture means it provides long-term support, making it ideal for skin closure and other applications where the wound may take longer to heal or where permanent support is desired. The USP 2-0 size is a versatile gauge that is commonly used in a wide range of surgical procedures, offering a good balance between tensile strength and tissue approximation.

The 76cm suture length provides ample material for most closure needs, allowing for secure knot tying without being excessively long. The black color of the suture enhances visibility against the surgical field, facilitating precise placement and knotting. The radiation sterilization ensures that the product is safe for use in sterile surgical environments.

The 12 foils per box provide a convenient quantity for stocking and use in surgical settings. The combination of these features makes this suture a reliable choice for medical professionals performing a variety of surgical procedures.
