Castroviejo Needle Holder Number 5020M Straight Tungsten Carbide 14cm - Hu-Friedy - Delynov

What is the Hu-Friedy Castroviejo #5020M needle holder?

The Castroviejo #5020M needle holder manufactured by Hu-Friedy is a high-end microsurgery instrument designed for demanding practitioners. This model is distinguished by its straight structure and its 14cm length, offering a perfect balance for delicate manipulations in the oral cavity. Its main feature lies in the integration of tungsten carbide jaws, a material recognized for its extreme hardness and its ability to maintain a reliable grip on the steel of the needles. This device belongs to Class I of medical devices, guaranteeing its compliance with basic regulatory requirements for reusable surgical instrumentation. Its ergonomic design allows for precise force transmission, limiting fatigue during prolonged suturing sessions in oral surgery.

What are the clinical indications for this straight needle holder?

This straight needle holder is specifically indicated for interventions requiring high execution finesse. In implant surgery and periodontology, it is the instrument of choice for soft tissue management, particularly during the placement of connective tissue grafts or sutures of coronally positioned flaps. Its straight design facilitates direct access to surgical sites without major visual obstruction. The use of this tungsten castroviejo needle holder is particularly recommended when using small caliber suture threads, where needle stability is crucial to avoid any tissue tearing. It is also suitable for guided bone regeneration surgeries where the precision of the suture point determines the tightness of the primary closure.

What are the technical characteristics of this Hu-Friedy instrument?

The Castroviejo #5020M needle holder presents rigorous technical specifications. With a total length of 14cm, it allows for a stable and secure grip. The working part is equipped with tungsten carbide inserts (carb. Tungst.), welded or brazed onto the jaws, which gives the instrument wear resistance far superior to standard steel. This hardness allows for the maintenance of a sharp cross-hatch on the jaws, preventing the needle from rotating or slipping during trans-mucosal passage. The Castroviejo locking mechanism is designed for smooth engagement and disengagement, an essential characteristic for microsurgery where every sudden movement can compromise suture quality. This product is a Class I medical device manufactured by Hu-Friedy Mfg. Co., LLC.

What are the contraindications for the use of this device?

In accordance with information from the manufacturer Hu-Friedy, the use of this instrument is strictly reserved for qualified healthcare professionals. There are no specific medical contraindications listed other than those related to standard surgical protocols. However, manufacturer warnings regarding intended use must be respected. The instrument must not be used for tasks other than handling surgical suture needles proportioned to the size of its jaws. Use on needles of too large a caliber could prematurely damage the tungsten carbide inserts or distort the Castroviejo precision mechanism. It is imperative to read the instructions carefully before any use to guarantee patient safety and the longevity of the tool.

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

As a reusable surgical instrument made of steel and tungsten carbide, this straight microsurgery needle holder requires a rigorous sterilization and cleaning protocol. Although the instrument itself is not subject to resorption, its maintenance determines its functionality. It must be cleaned immediately after each intervention to prevent the fixation of organic debris. The manufacturer Hu-Friedy recommends the use of appropriate cleaning solutions and a steam sterilization cycle according to current standards for Class I devices. Particular attention must be paid to the drying of the Castroviejo mechanism to prevent any corrosion or seizing of the internal spring. Regular visual inspection of the tungsten jaws is advised to ensure the absence of dulling of the gripping micro-pyramids.
