Surgical suture, unabsorbable, monofil, polypropylene

Materials:

Thread: polypropylene crystalline stereoisomer and polyolefin.

Needle: treated stainless steel.

Specifications:

Non-absorbable, sterile surgical suture (CnH2n), esp. a synthetic resin of this type.

Blue pigmented suture to enhance visibility.

Polypropylene suture elicits minimal acute inflammatory reactions in tissues; suturing is followed by the gradual encapsulation of the suture by fibrous connective tissue.

Thread:

Monofilament is not absorbent, nor is it subject to degradation or weakening by the actions of tissue enzymes.

Monofilament polypropylene are infection-resistant, thus can be used on infected and contaminated wounds.

Its lack of adherence to tissue also facilitates its use as a pull-out suture.

The suture thread is slippery, it requires a 4-throw knot to secure the end.

Thread gauge

Indicated in USP (Unite States pharmacopoeia) and EP (European pharmacopoeia).

Type:

Eyeless with the thread attached and mounted on the needle.

Point:

A cutting needle, it has a triangular point with two edges in the horizontal plane and one edge in the vertical plane.

- In a regular cutting needle the vertical edge is located on the inner curvature.

- A cutting needle is designed to cut through dense, difficult-to-penetrate tissue, such as skin.

Shape:

The degree of curvature is described in terms of circumference in &fraq12; to ³/₈ of a circle.

Length:

available in different length (18-48mm)

Components:

Vascular suture, double needle (one needle on each end of the thread) rounded point, used for the suturing of blood vessels.

Packaging:

Box, with 36 individually-packaged sutures with the following indications:

- Thread composition and material

- Thread Gauge size in USP and EP

- Needle point and length

- Sterilization method (ethylene oxide)

- Expiration date

Comments:

Do not re-sterilize: once opened discard all unused sutures and ligatures

Re-sterilizing causes materials to lose their strength and pliability.

Other:

Suture quality must meet the characteristics and tests described in the EU and US pharmacopoeias.

Must comply with European Medical Device Directive 93/42/EEC or American Directives 21CFR820
