Ethicon Johnson - NW3340 - Ethilon Sutures - NW3340 USP 0, 1/2 Circle Round Body - 12 Foils Box

This product is a non-absorbable, synthetic monofilament surgical suture composed of nylon. It is designed for use in surgical procedures where permanent tissue support is required. The suture is black in color, which can aid in visibility during the procedure.

Each unit contains a 150cm length of suture material attached to a 40mm needle. The needle is characterized by its 1/2 circle curvature and round body design, intended for precise tissue penetration and manipulation. The suture is supplied in a sterile, foil-wrapped packaging, with 12 individual foils per box, ensuring product integrity until the point of use.

The material's non-absorbable nature means it will remain in the tissue indefinitely, providing long-term tensile strength. The tensile strength retention profile indicates a gradual decrease over time, with approximately 20% loss in retention strength per year. This characteristic is important for surgeons to consider when selecting sutures for specific applications and expected healing timelines.

The mechanism of action for this suture involves approximating wound edges or securing tissues together. The monofilament construction minimizes drag through tissue compared to braided sutures, potentially reducing tissue trauma. The nylon material offers good knot security and a smooth passage through tissues.

The round body needle is versatile and suitable for a range of tissue types, allowing for controlled entry and exit to minimize damage. The non-absorbable nature ensures that the suture maintains its structural integrity over extended periods, which is crucial for applications requiring sustained wound closure or support, such as in cardiovascular surgery, ophthalmology, or plastic and reconstructive procedures where long-term tissue approximation is paramount.

Key features of this surgical suture include its synthetic, non-absorbable composition, providing predictable and lasting tensile strength. The monofilament structure contributes to reduced tissue reactivity and easier handling. The black coloration enhances visualization in the surgical field, which can be particularly beneficial in procedures with limited lighting or complex anatomical structures.

The specific needle dimensions and curvature (40mm, 1/2 circle round body) are engineered for optimal performance in various surgical scenarios, facilitating accurate placement and secure knot tying. The product is supplied in a sterile, multi-foil packaging, ensuring aseptic conditions for surgical use and offering convenience for stocking and dispensing in healthcare settings.

This type of surgical suture is utilized by a wide range of medical professionals, including surgeons, surgical nurses, and other trained healthcare providers involved in operative procedures. Patients undergoing surgical interventions requiring durable tissue closure would indirectly benefit from its application. Caregivers may also encounter this product in post-operative care settings.

The suture's properties make it suitable for numerous surgical specialties. Typical applications include approximating skin edges for cosmetic closure, reinforcing tissues in abdominal surgeries, securing grafts in reconstructive procedures, and in various other surgical interventions where permanent tissue support is a requirement. Its non-absorbable nature makes it a reliable choice for long-term wound management and tissue stabilization.

Important usage notes pertain to proper handling and sterilization protocols. As a non-absorbable suture, it is intended for permanent placement and should not be used in situations where eventual absorption is desired. Surgeons must be aware of the suture's tensile strength retention characteristics when planning for long-term tissue support.

Appropriate knot tying techniques should be employed to ensure secure closure without excessive tension, which could lead to tissue damage. The sterile packaging must be inspected for integrity before use, and the suture should only be used if the packaging is intact and within its expiration date. Disposal of used materials should follow established medical waste management guidelines.
