Needle Holder Castroviejo Number 5021M Tungsten Carbide Curved 14cm - Hu-Friedy - Delynov

What is the Hu-Friedy Castroviejo #5021M needle holder?

The Castroviejo #5021M needle holder from the Hu-Friedy brand is a high-end micro-surgery instrument intended for demanding practitioners. This model is distinguished by its fine structure and precise locking mechanism, allowing suture needles to be held without risk of slipping. Its design integrates tungsten carbide inserts at the jaws, a material recognized for its extreme hardness and superior longevity compared to standard steel. With a total length of 14cm, this instrument offers an optimal balance between maneuverability and tactile control. Manufactured by Hu-Friedy Mfg. Co., LLC, this device is specifically adapted for interventions requiring great finesse of movement, particularly in periodontal plastic surgery or during the closure of complex implant sites.

What are the clinical indications for this instrument?

The Hu-Friedy curved Castroviejo needle holder is indicated for all oral surgery interventions requiring the use of small calibre suture threads. In implantology, it is particularly useful for suturing flaps after bone augmentation or membrane placement, where stitch precision is crucial for primary intention healing. In periodontology, its fineness allows for interrupted sutures or sling stitches during connective tissue grafts or coronally advanced flaps. The curved shape of the working part greatly facilitates access to palatal areas or posterior molar sectors, where working space is limited. This instrument is strictly reserved for qualified healthcare professionals mastering micro-suture techniques.

What are the technical characteristics of this needle holder?

Technically, the Castroviejo #5021M needle holder features a length of 14cm, a standard format for micro-surgery guaranteeing an ergonomic grip. Its major characteristic lies in its jaws equipped with tungsten carbide inserts (carb. Tung.). This technology ensures a firm grip on the needle, limiting its rotation or tilting during trans-mucosal passage, while extending the instrument's lifespan against repeated mechanical stress. The curvature of the active tip allows for precise angulation when inserting the needle into soft tissues. The locking and unlocking system is calibrated to offer maximum fluidity, avoiding jerks that could traumatize the wound edges during thread manipulation.

What are the contraindications for the use of this device?

In accordance with information from the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this needle holder is exclusively reserved for duly trained healthcare professionals. Although no specific patient-related medical contraindications are listed for this instrument outside of standard surgical protocols, it must not be used for tasks for which it is not intended, such as handling thick steel wires or pins, which could damage the tungsten carbide inserts. Practitioners must refer to the indications and contraindications mentioned by the manufacturer Hu-friedy located at 3232 N. Rockwell St. Chicago, Il 60618 USA. It is imperative to read the instructions carefully before any use to guarantee patient safety and device integrity.

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

As this is a reusable metal surgical instrument and not a suture, the question of absorption does not apply. However, rigorous maintenance precautions are necessary to preserve the properties of the tungsten carbide and the Hu-Friedy steel. After each intervention, the instrument must be cleaned, decontaminated, and sterilized according to the protocols in force in dental offices or hospital environments. Particular attention must be paid to the locking mechanism and the jaws to eliminate any biological residue. Although robust, tungsten carbide can be sensitive to overly corrosive cleaning solutions or sudden thermal shocks. Compliance with the sterilization cycles recommended by Hu-Friedy ensures the longevity of the device and guarantees total aseptic safety for each new surgical act.
