Derf surgical needle holder with inserts, length 12 cm - Helmut Zepf (41.362.12) - Delynov

What is the Helmut Zepf Derf surgical needle holder?

The Derf surgical needle holder is a manual instrument designed by Helmut Zepf Medizintechnik GmbH for grasping and guiding suture needles. This specific model, referenced under code 41.362.12, features an optimized structure for micro-surgery and oral surgery procedures. Its design integrates robust jaws allowing for secure fixation of the needle, thus preventing any unwanted slipping or rotation during trans-gingival passage. With a total length of 12 cm, this instrument offers a balance between maneuverability and control, meeting the requirements of practitioners for delicate sutures in aesthetic or posterior zones.

What are the clinical indications for this needle holder?

In oral and implant surgery, this Derf needle holder is indicated for performing interrupted, continuous, or mattress sutures. It is particularly suitable for closing surgical sites after an extraction, implant placement, or periodontal surgery. Its small size of 12 cm makes it ideal for working in sectors where access is limited, allowing for precise manipulation of small-caliber threads. Surgeons use this Helmut Zepf instrument to ensure precise coaptation of wound edges, a determining factor for primary intention healing and the success of guided tissue regeneration procedures.

What are the technical characteristics of instrument 41.362.12?

The Helmut Zepf Derf needle holder is distinguished by its precise technical specifications adapted to the clinical environment. It has a length of 12 cm, making it a compact instrument promoting excellent tactile perception. The jaws are designed to provide maximum contact surface with the needle, thereby reducing the risk of metal twisting. The ratchet locking mechanism allows for maintaining constant pressure on the needle without continuous manual effort, thus freeing the practitioner's attention for the surgical gesture. The finish of the instrument is designed to limit reflections under surgical lighting, improving visual comfort during prolonged interventions.

What are the contraindications for the use of this device?

There are no specific absolute medical contraindications to the use of a needle holder forceps, other than those related to the surgical protocols themselves. However, the use of this instrument is contraindicated with needles of a caliber disproportionate to the size of the jaws, which could damage the precision mechanism or lead to needle instability. It must not be used to manipulate tissues (use as tissue forceps) or to twist rigid metal wires, at the risk of compromising jaw alignment. Practitioners must ensure the absence of known allergies to the metallic components of standard surgical instrumentation.

What are the maintenance precautions for this non-absorbable equipment?

As a reusable metallic instrument, this needle holder requires a rigorous sterilization protocol after each use. The manufacturer's recommendations from Helmut Zepf regarding cleaning, decontamination, and autoclaving should be followed. Particular attention must be paid to cleaning the hinge area and the ratchet notches to avoid the accumulation of biological residues. It is advisable to regularly inspect the condition of the jaws and the fluidity of the locking mechanism. Proper maintenance guarantees the longevity of the instrument and preserves its functional properties, essential for patient safety and the precision of the surgical gesture in the dental office.

Who is the manufacturer and what standards are respected?

The Derf needle holder is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision surgical instrumentation. Although specific details of the regulatory class or CE marking are not explicitly mentioned in the source data, this device is designed according to the industrial quality standards of the Helmut Zepf brand.
