Needle holder Derf groove 12.5cm - Hu-Friedy

What is the Hu-Friedy Derf needle holder?

The Derf needle holder manufactured by Hu-Friedy is a precision surgical instrument measuring 12.5cm. It is specifically designed for the manipulation of small needles in clinical settings. Its structure incorporates a crafted groove to stabilize the needle during transgingival passage, thereby preventing unwanted rotations. This instrument is part of the high-quality range from Hu-Friedy Mfg. Co., LLC, meeting practitioner requirements for procedures necessitating high dexterity. As a Class I device, it complies with the rigorous manufacturing standards imposed for non-invasive manual instrumentation, guaranteeing constant reliability during use in the office or operating room.

What are the clinical indications for this instrument?

This needle holder finds its primary application in oral surgery procedures, particularly for performing fine sutures. It is specifically indicated during periodontal surgeries, soft tissue grafts, or flap closures in implantology. Its ability to manage 6/0 calibre sutures makes it a choice tool for micro-surgery where suture point precision is critical for primary healing. The use of this dental derf needle holder allows the surgeon to exercise optimal control over the needle, facilitating the management of narrow interdental spaces and difficult-to-access areas while minimizing trauma to surrounding tissues.

What are the technical characteristics of the Derf needle holder?

The Derf needle holder is distinguished by a total length of 12.5cm, offering an ideal balance between leverage and maneuverability in the mouth. Its major technical characteristic lies in its internal groove, optimized for the firm hold of fine suture needles. It is designed to accommodate suture calibres ranging from 3/0 to 6/0. Manufacturing by Hu-Friedy ensures a surface finish and jaw alignment allowing direct transmission of the practitioner's force to the needle. This technical specificity reduces the risk of needle slippage, an essential factor when performing complex knots or precision sutures in demanding clinical environments.

What are the contraindications for the use of this device?

According to information provided by the manufacturer Hu-Friedy Mfg. Co., LLC, there are no specific medical contraindications listed for this Class I instrument, other than those related to general surgical practice. However, the use of this instrument is strictly reserved for qualified healthcare professionals. It is imperative not to use this needle holder with needles of a calibre larger than 3/0, as this could damage the locking mechanism or deform the grooved jaws. As with any surgical instrument, a visual inspection before use is necessary to ensure the absence of defects, and careful reading of the instructions for use is mandatory before any intervention.

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

Although the term 'resorption' applies to suture materials, the durability of this Hu-Friedy instrument depends on its maintenance protocol. As a Class I metallic instrument, it must undergo a complete cycle of cleaning, disinfection, and sterilization between each patient. It is recommended to use neutral pH cleaning solutions to preserve the integrity of the steel and the groove. Particular attention must be paid to drying to prevent any corrosion. The hinge mechanism must be lubricated periodically with a product suitable for autoclavable medical devices. Compliance with these precautions ensures that the needle holder retains its gripping properties for micro-surgery sutures over the long term.
