Helical shaft for bone crusher, length 47.954 mm - Helmut Zepf (47.954.35) - Delynov

What is the Helmut Zepf helical shaft for bone grinder?

The helical shaft for bone grinder, referenced under code 47.954.35 by the manufacturer Helmut Zepf Medizintechnik GmbH, is a central mechanical part designed for autologous bone processing systems. This component features a specific helical structure allowing for the driving and fragmentation of bone blocks harvested from the patient. As a bone mill accessory, it plays a decisive role in the grinding kinetics. Its robust design meets the requirements of oral surgery for the preparation of recipient sites. This device is specifically sized to integrate into the Helmut Zepf brand instrumentarium, ensuring optimal force transmission during manual or mechanical rotation of the grinding device.

What are the clinical indications for this helical shaft?

This helical grinder shaft is indicated during pre-implant surgery and periodontology procedures requiring an autologous bone graft. It is used after the harvesting of a bone block, generally at mandibular or maxillary sites. The use of this bone grinder shaft allows massive fragments to be transformed into particles of suitable grain size to fill bone defects, perform ridge augmentations, or sinus lifts. By facilitating grinding, it helps the practitioner obtain a filling material that promotes revascularization and future osseointegration of the implants. Its use is strictly reserved for healthcare professionals trained in bone reconstruction techniques and the handling of autogenous tissues.

What are the technical characteristics of this accessory?

The Helmut Zepf helical shaft features precise technical specifications to ensure its function within the mill. Its total length is 47.954 mm, a critical dimension to ensure perfect alignment and stability during rotation in the grinder body. The geometry of the helix is studied to maximize contact with the bone tissue while minimizing thermal heating during fragmentation. As a bone grinder spare part, it is designed to withstand the significant mechanical stresses related to the density of cortical bone. The technical reference 47.954.35 allows for precise identification of the model within the Helmut Zepf range, thus ensuring proper maintenance of the oral surgery equipment used in dental offices or hospital environments.

What are the contraindications for the use of this device?

The contraindications for the use of this helical shaft are mainly related to the general contraindications of bone graft surgery. The use of this bone mill accessory should not be considered if the patient presents with serious systemic pathologies compromising bone healing, or in the event of active infections at the harvest or recipient site. It is also necessary to ensure the absence of known allergies to the metallic components of the instrument. On a technical level, the use of the shaft is contraindicated if it shows marked signs of wear, deformations, or structural damage that could release metallic particles or alter the quality of the bone grinding. The practitioner must systematically refer to the manufacturer's technical instructions to validate the suitability of the device.

What are the maintenance and handling precautions?

Like any reusable surgical instrument, this helical shaft requires a strict protocol of cleaning, disinfection, and sterilization between each patient. After each use, it is imperative to disassemble the grinder to extract the shaft and eliminate all organic residues lodged in the helix turns. The use of suitable brushes and enzymatic cleaning solutions is recommended to preserve the integrity of the surface. A thorough visual inspection must be carried out before each sterilization cycle to check for the absence of corrosion or dulling of the sharp edges. Appropriate lubrication of friction points, in accordance with the recommendations of Helmut Zepf Medizintechnik GmbH, may be necessary to guarantee the fluidity of the rotation mechanism and prolong the operational life of the part.

Who is the manufacturer and what standards are respected?

The helical shaft for bone grinder is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the field of high-precision surgical instrumentation. Based in Germany, this company applies rigorous manufacturing standards to guarantee the reliability of its medical devices. Although the specific regulatory class and CE marking are not detailed in the simplified technical documentation, Helmut Zepf products are developed according to the quality requirements specific to surgical instruments intended for oral surgery. Compliance with the sterilization and maintenance protocols recommended by the manufacturer is essential to maintain the performance of the device. For any additional information on certifications or regulatory compliance, it is advisable to consult the official documentation provided by Delynov or directly from the manufacturer.
