SERALON non-absorbable blue (4/0) HR-15 needle 50 cm box of 24 sutures - Serag & Wiessner (VO151739) - Delynov

What is the non-absorbable blue SERALON (4/0)?

SERALON, manufactured by Serag-Wiessner, is a synthetic, non-absorbable surgical suture material. It is a monofilament thread made of polyamide, more commonly known as nylon 4/0 suture in clinical practice. This device is distinguished by its smooth monofilament structure, colored with phthalocyanine blue for increased visibility during the intervention. Compliant with the European Pharmacopoeia, this blue non-absorbable suture thread is particularly valued for its flexibility and its ability to pass through tissues without a saw effect, thus minimizing tissue trauma during stitching.

What are the clinical indications in oral surgery?

Although the general intended use is surgical suturing, SERALON 4/0 is frequently used in oral, periodontal, and implant surgery. Its nature as a polyamide 4/0 suture makes it ideal for closing muco-periosteal flaps and for approximation sutures after an extraction or implant placement. As a blue non-absorbable suture thread, it allows for easy identification during the healing phase and facilitates its subsequent removal. Its monofilament structure is a major asset in the oral environment, as it significantly reduces the risk of capillarity and bacterial colonization compared to braided threads.

What are the technical characteristics of the HR-15 needle?

Product VO151739 is equipped with an HR-15 needle swaged on a 50 cm thread. According to technical nomenclature, the HR code designates a 1/2 circle round-bodied needle. This configuration is specifically indicated for deep sutures and ligatures, allowing for precise handling in the restricted spaces of the oral cavity. The number 15 indicates a needle body length of 15 mm. This robust needle allows for penetration through soft tissues while limiting the risk of tearing, thus offering optimal control to the practitioner when performing simple stitches or mattress sutures.

What are the contraindications for the use of this suture?

The use of SERALON from Serag-Wiessner has strict contraindications defined by the manufacturer Serag-Wiessner GmbH & Co. KG. It is formally contraindicated for any use in direct contact with the heart, the central nervous system, or the central circulatory system. Furthermore, due to a progressive loss of tensile strength in the body over time, this non-absorbable 4/0 suture thread must not be used when prolonged and permanent mechanical stability of the material is essential. Finally, its use is prohibited in patients with known hypersensitivity or allergies to polyamide or phthalocyanine blue dye.

What are the precautions related to its non-absorbable nature and handling?

As SERALON is a non-absorbable 4/0 suture thread, it requires manual removal once initial healing is achieved. Due to the high elasticity characteristic of polyamide monofilament threads, the manufacturer recommends making one or two additional knots (safety knots) to ensure the strength and hold of the suture over time. Particular attention should be paid when used in areas where the thread could remain in prolonged contact with saline solutions, such as the biliary or urinary tracts, as this can promote stone formation. In oral surgery, its smooth surface prevents irritation of surrounding tissues.

Who is the manufacturer and what standards are met?

This suture is produced by Serag-Wiessner GmbH & Co. KG, a recognized manufacturer based in Germany. The product benefits from a high level of regulatory compliance, being classified as a Class IIb medical device. It bears the CE1014 marking, guaranteeing compliance with European safety and performance requirements. Each box contains 24 sterile 50 cm sutures under the reference VO151739. The choice of this material by healthcare professionals ensures the use of a device tested and validated according to European Pharmacopoeia standards for non-absorbable synthetic sutures.

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.
