Needle Holder Derf Number 5032 Tungsten Carbide Striated 12cm - Hu-Friedy - Delynov

What is the Hu-Friedy Derf #5032 needle holder?

The Derf #5032 needle holder from the brand Hu-Friedy is a precision instrument intended for oral surgery. Its structure is distinguished by a total length of 12cm, making it a compact tool ideal for restricted workspaces. This model integrates tungsten carbide inserts in its jaws, recognizable by their superior hardness. The gripping surface is serrated, allowing the needle to be held firmly without risk of slipping or unwanted rotation during trans-mucosal passage. Manufactured by Hu-Friedy Mfg. Co., LLC, this instrument meets the quality requirements of practitioners performing delicate sutures in implantology or periodontology.

What are the clinical indications for this derf needle holder?

This derf needle holder is indicated for performing surgical sutures within the oral cavity. In implant surgery, it is used for the hermetic closure of surgical sites after implant placement or during guided bone regeneration procedures. Its short 12cm design is particularly suitable for posterior sectors where the patient's mouth opening limits the use of longer instruments. It is also suitable for the stabilization of soft tissue grafts and sutures of apically or coronally displaced flaps. Its use is strictly reserved for healthcare professionals trained in micro-surgery and intra-oral suture techniques.

What are the technical characteristics of this device?

The technical characteristics of this 12cm needle holder are based on the use of high-performance materials. The central element is the integration of tungsten carbide plates on the internal faces of the jaws. This material is chosen for its exceptional resistance to wear, extending the lifespan of the gripping serrations compared to conventional steel. The 12cm length offers a balanced lever arm for fine manipulation. The ratchet locking system allows a constant tension to be maintained on the needle without continuous manual effort, thus facilitating the precision of the suture point in demanding clinical conditions.

What are the contraindications for the use of this instrument?

According to information from the manufacturer Hu-Friedy Mfg. Co., LLC, the use of this instrument is exclusively reserved for qualified healthcare professionals. Contraindications include using the instrument for tasks other than the manipulation of surgical suture needles, such as twisting thick metal wires or removing crowns, which would damage the tungsten carbide inserts. There are no specific medical contraindications listed other than compliance with sterilization and asepsis protocols essential for any surgical intervention. The practitioner must consult the instructions before any use to ensure compatibility with the needles used.

What are the maintenance precautions for a non-absorbable instrument?

Although the term resorption applies to sutures, the durability of this metal needle holder depends on rigorous maintenance precautions. As a Class I instrument, it requires systematic decontamination, cleaning, and sterilization between each patient. It is imperative to follow Hu-Friedy's instructions regarding cleaning solutions so as not to alter the properties of the tungsten carbide. Particular attention must be paid to drying to avoid any corrosion. The hinge and ratchet mechanism must be checked regularly to ensure fluid movement and secure locking when grasping needles during the surgical act.
