Long Screwdriver - Helmut Zepf (47.833.04) - Delynov

What is the Helmut Zepf long screwdriver (47.833.04)?

The Helmut Zepf long screwdriver, referenced under code 47.833.04, is a manual instrument specifically designed for oral surgery and guided bone regeneration (GBR) procedures. Manufactured by Helmut Zepf Medizintechnik GmbH, this tool is crafted from high-quality medical stainless steel, ensuring compatibility with rigorous sterilization protocols in the practice. Its elongated structure is designed to provide optimal reach in difficult-to-access areas, allowing the practitioner to manipulate components with clear visibility. As a Class I device, it meets the safety requirements for non-invasive or temporary invasive instruments.

What are the clinical indications?

This screwdriver is indicated for use as a manual dental instrument during surgical procedures. In implantology and periodontology, it is primarily used in the fixation or adjustment steps of devices during guided bone regeneration (GBR). Its use is strictly reserved for qualified healthcare professionals. It allows for the screwing or handling of clinical micro-mechanical elements within the oral environment, particularly when the depth of the surgical site requires an instrument of greater length to maintain a clear visual field and precise movement without obstruction by surrounding tissues.

What are the technical characteristics?

The Helmut Zepf long screwdriver is distinguished by its technical reference 47.833.04. It is designed in medical stainless steel, a material chosen for its resistance to repeated decontamination cycles. The instrument is delivered non-sterile and must undergo a complete cycle of cleaning, disinfection, and sterilization before its first use, as well as between each patient. Its monobloc or assembled design (according to Helmut Zepf standards) aims to minimize areas of biological debris retention. The specific length of this "long" model is calibrated to meet the needs of surgeons working on posterior sectors or complex anatomies.

What are the contraindications for use?

The main contraindication mentioned by the manufacturer Helmut Zepf concerns patients with a known hypersensitivity or intolerance to metals, particularly medical stainless steel. An allergic or hypersensitivity reaction can be triggered upon contact of the instrument with tissues. If such a reaction occurs during the intervention, the procedure must be immediately interrupted and necessary medical measures must be taken. Furthermore, it is strictly forbidden to use the instrument if it shows visible damage such as cracks, breaks, or defects on the active parts, as this could compromise patient safety.

What are the maintenance and reprocessing precautions?

As a non-resorbable and reusable instrument, the screwdriver must follow a strict reprocessing protocol. Helmut Zepf Medizintechnik GmbH specifies that due to the product design and materials used, there is no defined maximum limit for treatment cycles, as long as the instrument does not show functional wear. Before each use, the practitioner must check for the absence of visible damage. Cleaning must be meticulous to remove all organic residue before sterilization. It is also crucial to check the compatibility of this screwdriver with other medical devices used simultaneously during the surgical act to avoid premature wear or technical failure.

Who is the manufacturer and what standards are respected?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Seitingen-Oberflacht, Germany. This long screwdriver is classified as a Class I medical device (Class Ir according to certain reprocessing nomenclatures). It complies with the regulatory requirements applicable to manual dental instruments. The manufacturer emphasizes that its products are delivered non-sterile and that the responsibility for implementing sterilization processes lies with the healthcare professional. Compliance with the instructions for use and safety provided by Helmut Zepf is essential to guarantee the longevity of the instrument and clinical safety during bone surgery phases.
