Surgical screw rack for 1.5 and 2.0 mm diameters in maxillofacial surgery - Helmut Zepf (85.540.55) - Delynov

What is the Helmut Zepf screw rack (85.540.55)?

The Helmut Zepf screw rack, bearing reference 85.540.55, is an instrumental management device specifically designed for maxillofacial surgery. This surgical screw storage support allows for the holding and organization of small diameter screws, specifically those of 1.5 mm and 2.0 mm. Manufactured by Helmut Zepf Medizintechnik GmbH, this rack is structured to meet the requirements of sterilization and handling in the operating room. It ensures a clear presentation of the components necessary for osteosynthesis or bone block fixation, thus avoiding loss of time or material during the surgical act. Its robust design guarantees optimal stability on the instrumentation tray.

What are the clinical indications for this maxillofacial screw rack?

This maxillofacial screw rack is indicated for all interventions requiring the use of 1.5 and 2.0 mm diameter screws in the oral and maxillofacial sphere. Its use is particularly relevant during Guided Bone Regeneration (GBR) procedures, onlay bone grafts, or the stabilization of membranes and osteosynthesis plates. As a maxillofacial screw support, it allows the practitioner to quickly select the appropriate screw length from the 1.5 and 2.0 mm diameters. This device is an indispensable logistical tool for maintaining asepsis and organization of the surgical field during complex reconstructive surgeries where the precision of the fixation material is critical for the success of bone integration.

What are the technical characteristics of this screw storage rack?

The screw storage rack referenced 85.540.55 by Helmut Zepf features technical characteristics adapted to 1.5 mm and 2.0 mm diameter micro-screws. Although the exact dimensions are not specified, its structure is designed to accommodate these two distinct calibres securely. The tray configuration allows for immediate visual identification of the different diameters available. This GBR category device is developed by Helmut Zepf Medizintechnik GmbH to withstand repeated cleaning and sterilization cycles in an autoclave, typical of surgical environments. Its internal geometry is designed so that the screws remain in a vertical position, facilitating their direct pickup by the screwdriver or holder without risk of tipping.

What are the contraindications for the use of this device?

As an organization and storage accessory, this screw rack does not present direct clinical contraindications related to biological interaction with the patient, as it is not intended to be implanted. However, its use is contraindicated for the storage of screws with a diameter other than 1.5 mm or 2.0 mm, as this could compromise the stability of the screw retention or damage the rack. It is imperative not to use the device if it shows visible signs of corrosion, deformation, or structural damage that could hinder the sterilization process or the safety of screw handling. Practitioners must systematically refer to the cleaning protocols of the manufacturer Helmut Zepf.

What are the maintenance precautions for this maxillofacial screw support?

The Helmut Zepf maxillofacial screw support must be subject to a rigorous maintenance protocol in accordance with oral surgery standards. Being a reusable device, it must be cleaned and sterilized before each use. It is recommended to use neutral pH cleaning solutions to preserve the integrity of the rack's surface. During the decontamination process, it should be ensured that all cavities intended for 1.5 and 2.0 mm screws are free of organic residues. After sterilization, the rack must be stored in a dry and protected environment. Regular visual inspection is necessary to confirm the absence of premature wear, thus guaranteeing the longevity of the equipment within the surgical arsenal of the practice or clinic.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the high-precision surgical instrumentation sector. This surgical screw rack (reference 85.540.55) is designed according to the rigorous quality standards specific to the German medical industry. Although the specific regulatory class and CE marking are not detailed in the provided technical documentation, Helmut Zepf products are developed to meet the safety and performance requirements of medical devices used in maxillofacial surgery. For any precise information regarding current certifications or specific ISO standards applied to this storage rack, it is advisable to consult the technical instructions or contact the manufacturer directly.
