Ethicon Johnson - NW5017P - Mersilk Sutures USP 0, 3/8 Circle Round Body - NW5017 - 12 Foils Box

This product is a non-absorbable surgical suture constructed from braided silk filaments, derived from the Bombyx mori silkworm. The suture material undergoes a beeswax coating process, which aids in handling and knot security during surgical procedures. Each suture strand measures 76 centimeters in length and is black in color, designed for clear visibility in the surgical field.

The suture is classified under USP size 0, indicating its diameter and suitability for various tissue types. The suture is pre-attached to a 30mm, 3/8 circle round body needle, crafted from SS 420 stainless steel alloy, which is silver in color. This needle configuration is designed for efficient penetration and manipulation in surgical settings.

The mechanism of action for this suture involves providing a means to approximate or ligate tissues during surgical interventions. As a non-absorbable material, it is intended for applications where prolonged wound support is required, or where the suture material is not meant to be absorbed by the body. The braided construction offers good tensile strength and pliability, facilitating secure knot tying and reducing the risk of suture breakage.

The beeswax coating enhances the suture's handling characteristics, making it easier for surgeons to manipulate and tie knots with precision. The round body needle is typically used for suturing soft tissues, allowing for good tissue passage and minimizing trauma.

Key features of this surgical suture include its natural braided silk composition, providing a balance of strength and flexibility. The non-absorbable nature ensures sustained tissue approximation over an extended period. The pre-attached needle with a specific curvature and length is designed for optimal surgical access and tissue manipulation.

The 30mm needle length and 3/8 circle configuration are suitable for a range of surgical procedures. The black color of the suture enhances its visibility against tissue, aiding in precise placement and removal if necessary. The suture's tensile strength is maintained for approximately three months post-implantation, offering robust support during the initial stages of wound healing.

This surgical suture is utilized by a variety of medical professionals, including surgeons, surgical residents, and other trained healthcare providers performing surgical procedures. It is also relevant for use by surgical nurses and technicians who assist in surgical settings. While primarily used by professionals, caregivers involved in post-operative wound management may encounter such sutures.

The typical applications span across numerous surgical specialties, including general surgery, cardiovascular surgery, plastic surgery, and ophthalmic surgery, where secure tissue approximation and prolonged support are critical. It is particularly useful in closing layers of tissue, such as the seromuscular layer of the gastrointestinal tract, or for skin closure where permanent or semi-permanent support is desired.

Usage of this suture requires adherence to standard sterile surgical techniques. The suture and needle are supplied sterile and should only be used if the packaging remains intact. It is important to select the appropriate suture size and needle type for the specific surgical application and tissue being sutured to minimize tissue trauma and ensure optimal wound healing.

The non-absorbable nature means that if suture removal is indicated, it must be performed by a qualified healthcare professional. The prolonged retention of tensile strength necessitates consideration for potential long-term tissue reactions or the need for removal in certain clinical scenarios. Sterilization is achieved through radiation, ensuring the product is safe for surgical use upon opening.
