Castroviejo needle holder round car. Tun. Serrated 14cm - Hu-Friedy - Delynov

What is the Hu-Friedy round Castroviejo needle holder?

The Castroviejo needle holder from Hu-Friedy is a high-end micro-surgery instrument designed for demanding practitioners. This model stands out for its round and serrated handle, offering an excellent grip and allowing for precise axial rotation when passing the needle through tissues. Its structure integrates tungsten carbide (car. Tun.) inserts, a material recognized for its extreme hardness, guaranteeing a firm hold of the needle without slipping. With a total length of 14cm, this instrument manufactured by Hu-Friedy Mfg. Co., LLC combines finesse and robustness to meet the specific needs of surgical interventions in odontology and periodontology.

What are the clinical indications for this needle holder?

This dental tungsten needle holder is primarily indicated for micro-surgery procedures where precision of movement is critical. In implant surgery, it allows for precise sutures around abutments or during flap closure. In periodontology, its finesse is a major asset for subepithelial connective tissue grafts or periodontal plastic surgeries requiring low-calibre threads. Its Castroviejo design facilitates work under optical aids (loupes or microscope) by minimizing sudden movements during the locking or unlocking of the instrument, thus preserving the integrity of the manipulated soft tissues.

What are the technical characteristics of this instrument?

The technical characteristics of this Hu-Friedy model are based on precision engineering. The instrument has a length of 14cm, a standard format for optimal maneuverability in the mouth. The working part is equipped with serrated tips reinforced by tungsten carbide, which limits premature wear of the contact surfaces and prevents untimely rotation of the needle. The round serrated handle is specifically studied to promote an ergonomic grip, allowing the surgeon to adjust the insertion angle of the needle by simply rolling the instrument between the thumb and index finger, without excessive wrist tension.

What are the contraindications for the use of this device?

There are no specific absolute medical contraindications to the use of this needle holder, other than those related to the surgical protocols themselves. However, it is not recommended to use this instrument to handle very large calibre needles or metal wires that could damage the fine tungsten carbide inserts. Use on materials not intended for surgical suture is also prohibited to maintain the alignment of the tips. As with any surgical instrument, a known allergy to the metals constituting the alloy must be taken into account before handling.

What are the maintenance precautions for this non-absorbable needle holder?

As it is a reusable metallic instrument, the Hu-Friedy needle holder requires a rigorous sterilization and cleaning protocol after each intervention. It is recommended to follow the instructions from the manufacturer Hu-Friedy Mfg. Co., LLC regarding decontamination, thermal cleaning, and autoclave sterilization. Particular attention must be paid to cleaning the serrated tips to eliminate any biological residue. Although tungsten carbide is extremely resistant, inappropriate maintenance or the use of corrosive chemicals can alter the properties of the steel and the inserts, compromising the precision of the Castroviejo locking mechanism.

Who is the manufacturer and what standards are respected?

The needle holder is manufactured by Hu-Friedy Mfg. Co., LLC, a manufacturer recognized worldwide for the quality of its dental instrumentation. Although specific regulatory class or CE marking data are not detailed in the current technical sheet, Hu-Friedy products are generally designed according to strict industrial standards for professional use in surgical environments. The practitioner is invited to consult the product labeling and the instructions for use provided by the manufacturer to verify the certifications in force, reprocessing instructions, and compliance with local regulatory requirements regarding reusable medical devices.
