SERAFAST absorbable violet (6/0) DSS-13 needle of 70 CM box of 24 sutures - Serag & Wiessner (JO07321L) - Delynov

What is the SERAFAST absorbable violet (6/0) suture?

SERAFAST is a synthetic, absorbable, monofilament surgical suture material designed by the renowned manufacturer Serag-Wiessner. It is composed of a segmented copolymer combining glycolide and e-caprolactone. This monofilament structure ensures smooth passage through tissues, thereby limiting the wicking effect and the accumulation of bacterial plaque. Presented here in 6/0 (USP) calibre, this thread is dyed violet with D+C No 2 dye (Colour Index No. 60725) to provide increased visibility during the procedure. It meets the requirements of the European Pharmacopoeia for sterile synthetic absorbable monofilament sutures.

What are the clinical indications for this device?

The SERAFAST suture from Serag-Wiessner is specifically indicated for soft tissue adaptation or for performing ligatures when an absorbable suture material with rapid kinetics is required. In oral and implant surgery, its use is preferred for flap closures or sutures of thin mucous membranes where mechanical support is only necessary for a limited period, generally up to two weeks. Its fineness (6/0 calibre) and its length of 70cm allow for precise handling for delicate tissues requiring rapid healing and minimally invasive intervention.

What are the technical characteristics of the DSS-13 needle?

The needle equipped with this reference is a DSS-13. According to the Serag-Wiessner technical nomenclature, the code DSS designates a 3/8 circle needle equipped with an atraumatic triangular reverse-cutting tip. This geometry is particularly suitable for dense tissues or thin mucous membranes, as it allows for facilitated penetration without the risk of excessive tissue tearing. The number 13 indicates a needle body length of 13mm, a standard dimension for precision interventions in the oral area. Manufactured from high-quality surgical steel, it guarantees constant rigidity and sharpness throughout the duration of the suturing.

What are the contraindications for the use of SERAFAST suture?

The use of SERAFAST is formally contraindicated in clinical situations requiring prolonged or lasting mechanical stability of the suture material. For example, it must not be used for the fixation of synthetic implants such as heart valves. Furthermore, this device is not intended for interventions involving the central cardiovascular system or the central nervous system. Finally, its use is prohibited in patients with a known allergy to any of its components, namely glycolide, e-caprolactone, or the violet D+C No 2 dye.

How does resorption occur and what are the precautions?

SERAFAST is a rapidly absorbable material, designed to lose its tensile strength significantly after approximately two weeks. Resorption occurs by hydrolysis, a predictable process that minimizes tissue inflammatory reaction. The choice of this material must take into account these rapid degradation kinetics; it is therefore not suitable for surgical sites subject to high prolonged mechanical tension. Particular caution is recommended in patients with delayed healing, as the loss of breaking strength of the suture could precede complete wound closure.

Who is the manufacturer and what standards are respected?

This medical device is manufactured by Serag-Wiessner GmbH & Co. KG, a company based in Naila, Germany. As a Class III medical device, it bears the CE1014 marking, guaranteeing its compliance with the strictest European regulatory requirements (MDR). The suture material is produced in accordance with the European Pharmacopoeia monograph relating to sterile synthetic absorbable monofilament threads. Each box contains 24 sterile 70cm sutures, referenced under code JO07321L, ensuring optimal traceability and safety of use for oral surgery practitioners.

State of the art

Modern synthetic sutures - absorbable or non-absorbable - are central to wound healing in oral surgery. Recent advances focus on reducing post-operative infections.
