The Daclon nylon blue 5/0 DS 12 refers to a specific non-absorbable, monofilament surgical suture with a DS 12 reverse cutting needle used primarily for skin closure and microsurgery. 

Product Specifications:

The SMI Daclon nylon suture, blue, with a DS 12 needle has the following characteristics:

Material: Nylon (Polyamide 6.0), monofilament.

Absorbability: Non-absorbable; it maintains long-term tensile strength and is gradually encapsulated by connective tissue.

Color: Blue, which improves visibility and manipulation during surgery.

Suture Size: 5/0 (USP).

Needle Type: DS (Reverse Cutting). This type is typically used for skin closure because the cutting edge on the outer curve helps prevent cut-through of the tissue.

Needle Dimensions: 12 mm length, 3/8 circle curvature.

Length: Typically 75 cm.

Packaging: Usually supplied in a box of 12 sterile, individually packed units.

Applications and Features:

Key Features: Daclon sutures are known for their high tensile strength, smooth handling, and minimal tissue reaction. They are easy to manipulate and facilitate simple and secure knots.

Common Uses: They are frequently used in general surgery, skin closure (plastic surgery), and microsurgery.
