Ethicon Johnson - NW5037P - Mersilk Sutures USP 0, 3/8 Circle Reverse Cutting - NW5037 - 12 Foils Box

This product is a non-absorbable surgical suture, identified by the product code NW5037. It is constructed from braided silk, a natural protein-based fiber, which provides strength and handling characteristics suitable for various surgical applications. The suture is dyed black for enhanced visibility during procedures.

The suture material conforms to USP (United States Pharmacopeia) standards for size, designated as USP 0. This size indicates a moderate diameter, offering a balance between tensile strength and tissue passage. The suture is 76 centimeters in length, providing adequate material for closure of wounds or tissues.

The needle attached to the suture is a 45 mm long, 3/8 circle reverse cutting needle. The reverse cutting needle design features a triangular point with the cutting edge on the outer curvature of the needle shaft, which can reduce tissue drag and is often preferred for dense or tough tissues. The needle is made from SS 420 stainless steel alloy, known for its hardness and corrosion resistance.

Sterilization is achieved through radiation, ensuring the product is sterile for surgical use. Each box contains 12 individually foil-packaged sutures. This suture is intended for use in procedures where prolonged tissue support is required or where the suture is to be removed post-healing, as silk is a non-absorbable material.

The braided construction of the silk suture allows for secure knot tying and good tensile strength retention. The natural fiber composition offers a degree of pliability and ease of manipulation, which can be beneficial for surgeons during tissue approximation. The non-absorbable nature means it remains in the tissue until manually removed, making it suitable for skin closure, fascial approximation, and other applications where temporary or permanent support is needed.

The product is designed for use by trained medical professionals in sterile surgical environments. Typical applications include general surgery, plastic surgery, and other specialties requiring a robust, non-absorbable suture for wound closure and tissue approximation. Careful consideration of the non-absorbable nature is important, as the suture will require removal if used in superficial tissues.

Proper aseptic technique must be maintained throughout the handling and use of this surgical product. The product is supplied in a sterile, ready-to-use format, with individual foil packaging designed to maintain sterility until the point of use. The black dye enhances visualization against various tissue types, aiding in precise placement and knot tying.

The combination of the braided silk material and the reverse cutting needle offers a versatile option for surgeons managing a range of tissue types and surgical scenarios. The 3/8 circle needle geometry is commonly used in surgical fields where maneuverability within confined spaces is important.
