Ethicon Johnson - NW3322 - Ethilon Sutures - NW3322 USP 8-0, 3/8 Circle Spatulated Mircopoint -12 Foils Box

This product consists of Ethilon sutures, a synthetic, non-absorbable surgical thread manufactured from polyamide. The material is presented in a monofilament construction, meaning it is a single, solid strand, which contributes to its smooth passage through tissue and reduced drag. The suture is colored black, which can aid in visibility during surgical procedures, particularly in darker operative fields.

Each box contains 12 individual foil-wrapped units, ensuring sterility until the point of use. The suture thread itself has a diameter designated as USP 8-0, representing a very fine gauge suitable for delicate tissue approximation. The total length of the suture material on each unit is 38 centimeters.

This suture is intended for use on tissues where a non-absorbable material is required for sustained support or closure.

The accompanying needle is a crucial component for precise tissue manipulation. It features a 3/8 circle curvature, a common and versatile shape that allows for effective suturing in various anatomical locations. The needle's point is described as micro-point and spatulated.

The micro-point designation indicates an exceptionally fine and sharp tip designed for minimal tissue trauma upon penetration. The spatulated tip is flattened or spoon-shaped, which is particularly advantageous when working with delicate tissues like the conjunctiva or cornea, as it allows for controlled passage and minimizes the risk of tearing or damaging the tissue. The needle measures 6 millimeters in length and is constructed from Ethalloy, a proprietary needle alloy known for its strength and sharpness retention.

The needle is silver in color.

This type of suture is designed for use by qualified medical professionals in surgical settings. Its fine diameter and sharp, specialized needle make it appropriate for procedures requiring meticulous closure and minimal tissue disruption. The non-absorbable nature of the polyamide material means that it will remain in place indefinitely, providing long-term tensile strength.

This is essential for applications where permanent tissue support is necessary, such as in certain ophthalmic surgeries, plastic surgery, or other reconstructive procedures.

The typical applications for Ethilon sutures with a micro-point, spatulated needle include ophthalmic surgery, such as corneal or conjunctival repair, where precise and atraumatic suturing is paramount. It is also suitable for fine plastic surgery procedures, microsurgery, and other delicate tissue approximations where a small diameter, strong, and non-absorbable suture is indicated. The choice of suture size (USP 8-0) and needle configuration is dictated by the specific tissue type, the required strength of closure, and the surgeon's preference for handling and control.

Usage notes for this product include adherence to sterile surgical techniques. The sutures are sterilized using radiation, and the foil packaging should be inspected for integrity before use. Once the foil is opened, the suture and needle should be used immediately and any unused portion discarded.

Due to the non-absorbable nature of the polyamide, the suture will not break down in the body and may require removal in some applications, or it may be left in situ permanently depending on the surgical indication. The fine gauge and sharp needle require careful handling by the surgeon to prevent accidental needle-stick injuries or damage to the suture material.
