Long screwdriver - Helmut Zepf (47.833.09) - Delynov

What is the Helmut Zepf 47.833.09 long screwdriver?

The Helmut Zepf long screwdriver, referenced under code 47.833.09, is a specialized manual instrument used in oral surgery and implantology. Manufactured by Helmut Zepf Medizintechnik GmbH, this device is designed in medical stainless steel to ensure structural resistance adapted to mechanical stresses during screwing. This type of dental prosthesis screwdriver is distinguished by its elongated shaft, allowing the practitioner to reach surgical sites that are difficult to access, particularly in posterior sectors. It belongs to the Class I instrument category, intended for strict professional use in dental practices or hospital environments.

What are the clinical indications for this instrument?

This screwdriver is primarily indicated for the manual handling of components during implant surgery and guided bone regeneration (GBR) procedures. Its use is recommended for tightening or loosening cover screws, healing abutments, or osteosynthesis screws when the interdental space or the depth of the surgical site requires a reach superior to standard instruments. As a manual instrument, it provides precise tactile feedback to the dental surgeon, essential for controlling the initial tightening torque and ensuring the primary stability of prosthetic or bone fixation elements.

What are the technical characteristics of the 47.833.09 screwdriver?

The Helmut Zepf long screwdriver features technical characteristics defined by its reference 47.833.09. It is entirely designed in medical grade stainless steel, a material chosen for its biocompatibility and its ability to undergo repeated sterilization cycles. Its ergonomic design allows for a stable grip, reducing the risk of slipping during critical phases of the intervention. This device is delivered non-sterile by Helmut Zepf Medizintechnik GmbH, which requires a rigorous cleaning and sterilization protocol before the first use and between each patient, in accordance with the manufacturer's directives for Class I instruments.

What are the contraindications for the use of this screwdriver?

The main medical contraindication documented by the manufacturer Helmut Zepf concerns known hypersensitivity or intolerance to metals, specifically medical stainless steel. If a hypersensitivity reaction is triggered in the patient upon contact with the instrument, the clinical procedure must be immediately interrupted and necessary medical measures must be taken. Apart from these allergic reactions, use is contraindicated if the instrument shows visible damage such as cracks, breaks, or defects on the active parts, as this could compromise patient safety and the integrity of the handled prosthetic components.

What are the maintenance and reprocessing precautions?

Like any prosthetic surgery instrument, this screwdriver must undergo complete reprocessing before each use. As Helmut Zepf products are delivered non-sterile, they must be cleaned, disinfected, and sterilized according to current standards. It is imperative to check for the absence of wear or deformation before any use. Due to its design and the materials used, there is no defined maximum limit of treatment cycles, but compatibility with other products and the condition of the coupling edges must be systematically checked by the healthcare professional. The use of a damaged instrument is strictly prohibited.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This screwdriver is classified as a Class I medical device (Class Ir according to certain reprocessing nomenclatures). The manufacturer complies with regulatory requirements for manual dental instruments, ensuring that the stainless steel used meets medical quality standards. Each product is identified by a unique technical reference (47.833.09) allowing for complete traceability. Compliance with the safety and usage instructions provided by Helmut Zepf is mandatory to guarantee clinical performance and safety of care during dental surgery procedures.
