CRILE-WOOD NEEDLE HOLDER - Helmut Zepf (41.252.18TC) - Delynov

What is the Helmut Zepf CRILE-WOOD needle holder?

The Crile-Wood needle holder is a manual surgical instrument developed by Helmut Zepf Medizintechnik GmbH. This device is specifically designed to grasp, hold, and guide suture needles with high stability during tissue closure procedures. Its structure consists of two gripping jaws and a ratchet locking system, allowing the surgeon to maintain constant pressure without continuous manual effort. This instrument is a standard in oral surgery trays for soft tissue management.

What are the clinical indications for the Crile-Wood needle holder?

The Crile-Wood needle holder is indicated for a wide range of procedures in oral, implant, and periodontal surgery. It is used for suturing flaps after tooth extraction, placing guided bone regeneration membranes, or during muco-gingival surgeries. Its design allows for the manipulation of needles of various sizes to ensure precise coaptation of wound edges. It adapts to the needs of practitioners performing interrupted, continuous, or mattress sutures in areas where access may be restricted.

What are the technical characteristics of this instrument (41.252.18TC)?

The model referenced 41.252.18TC by Helmut Zepf is distinguished by the integration of specific jaws. Although full composition details are not specified, the 'TC' nomenclature generally suggests the presence of reinforced inserts to increase durability and grip quality. This instrument features a length and jaw fineness adapted to needles commonly used in dental surgery. The locking system is designed to provide a smooth release of the needle, thus avoiding traumatic jerks to the surrounding tissues during thread passage.

What are the contraindications for the use of this needle holder?

There are no absolute medical contraindications specifically linked to the instrument itself, other than those relating to the overall surgical procedure. However, the use of the Crile-Wood needle holder is discouraged with needles of a caliber disproportionate to the size of the jaws, which could damage the clamping mechanism or cause the needle to pivot uncontrollably. As with any metallic instrument, its use must be prohibited in patients with a known hypersensitivity to the constituent metals, if these are specified by the manufacturer.

What are the maintenance precautions for this non-resorbable device?

As a reusable surgical instrument, the Helmut Zepf needle holder requires a strict protocol of decontamination, cleaning, and sterilization between each patient. It is imperative to follow the recommendations of the manufacturer Helmut Zepf Medizintechnik GmbH regarding autoclave cycles and compatible cleaning products. Particular attention must be paid to the joint and the ratchet to avoid the accumulation of organic residues. Regular monitoring of jaw alignment and the integrity of the locking mechanism is essential to guarantee safety and efficiency during suturing.

Who is the manufacturer and what standards are respected?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision dental and surgical instrumentation. Although specific certifications such as regulatory class or CE marking are not detailed in the source data, this instrument is designed according to German industrial quality standards. For any information relating to regulatory compliance (MDR) or specific instructions for use, practitioners are invited to refer to the official technical documentation provided by Helmut Zepf or to consult the product labeling.
