Long Screwdriver - Helmut Zepf (47.833.06) - Delynov

What is the Helmut Zepf 47.833.06 long screwdriver?

The Helmut Zepf long screwdriver, referenced under code 47.833.06, is a specialized manual instrument for oral surgery and guided bone regeneration (GBR) procedures. Manufactured by Helmut Zepf Medizintechnik GmbH, this device is designed in high-quality medical stainless steel to ensure optimal resistance during clinical manipulations. Its elongated structure is specifically studied to offer increased accessibility in posterior areas or deep surgical sites, where standard instruments might lack reach. As a Class I device, it meets the basic regulatory requirements for non-invasive or invasive instruments for temporary use.

What are the clinical indications for this instrument?

This screwdriver is primarily indicated for implant surgery and bone reconstruction procedures. It serves as a manual instrument for the screwing and unscrewing of fixation components or abutments within the framework of guided bone regeneration protocols. Its use is reserved for qualified healthcare professionals, such as dental surgeons, implantologists, or stomatologists. It allows for controlled force transmission during the placement of stabilization devices, thus ensuring the precision necessary for the success of bone grafts or implant placement in complex anatomical environments.

What are the technical characteristics of the long screwdriver?

The Helmut Zepf screwdriver is distinguished by its technical reference 47.833.06. It is entirely designed in medical stainless steel, a material chosen for its biocompatibility and its ability to withstand repeated sterilization cycles. Unlike motorized instruments, this manual model offers direct tactile feedback to the practitioner, essential for assessing tightening torque. It is delivered non-sterile and requires a complete cleaning and sterilization protocol before its first use and after each intervention. Its compatibility with other fixation systems must be verified by the practitioner before the start of the surgical procedure.

What are the contraindications for the use of this device?

The main medical contraindication lies in the patient's known hypersensitivity or intolerance to metals, particularly to the medical stainless steel used in the manufacturing of the instrument. If an allergic reaction or hypersensitivity reaction occurs during contact with the instrument, the procedure must be immediately interrupted and necessary medical measures must be taken. Furthermore, the use of this screwdriver is strictly 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 surgical act.

What are the maintenance and reprocessing precautions?

As a reusable instrument, the Helmut Zepf long screwdriver must follow a rigorous reprocessing cycle. Before the first use and after each subsequent use, the instrument must be cleaned, disinfected, and sterilized in accordance with current hospital protocols. The manufacturer specifies that due to the design and materials used, there is no defined maximum limit for the number of treatment cycles, provided the instrument shows no functional wear. It is imperative to visually inspect the device before each intervention to detect any trace of corrosion or deformation. The use of damaged or worn products is formally prohibited.

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 screwdriver belongs to Class I according to the classification of medical devices (Class Ir - MDC0483 mentioned in the technical documentation). The manufacturer guarantees the compliance of its instruments with safety and performance requirements, although specific CE marking is not detailed in the source data. The product is intended exclusively for professional use by trained practitioners. Compliance with the instructions for use and safety provided by Helmut Zepf is essential to guarantee the longevity of the instrument and the safety of the care provided.
