Flohr ergonomic universal hex dental connector surgical cardan screwdriver - Helmut Zepf (47.502.25) - Delynov

What is the Helmut Zepf Flohr surgical cardan screwdriver?

The Flohr ergonomic handle surgical cardan screwdriver is a precision instrument designed by Helmut Zepf Medizintechnik GmbH for oral surgery procedures. This device is distinguished by the integration of a cardan joint between the handle and the active part, offering movement flexibility essential in restricted spaces. Its structure is specifically adapted to receive a universal hexagonal dental connector, thus allowing versatility of use with various fixation components. The Flohr-type ergonomic handle ensures a stable grip and torque control during the screwing phases, meeting the technical requirements of guided bone regeneration (GBR) protocols.

What are the clinical indications for this instrument?

This dental hexagonal screwdriver is primarily indicated in implant surgery and bone reconstruction procedures. Its use is preferred during the placement of membrane fixation screws or osteosynthesis screws in sectors where clinical angulation prevents the use of a standard straight screwdriver. The dental cardan screwdriver allows the practitioner to bypass anatomical obstacles or adjacent teeth while maintaining efficient force transmission. It finds its major application in the posterior zones of the maxilla and mandible, facilitating the implantologist's work during critical stages of graft stabilization or barrier device placement.

What are the technical characteristics of model 47.502.25?

The model referenced 47.502.25 by Helmut Zepf features technical specifications focused on modularity and accessibility. The central characteristic is its cardan mechanism which transforms this flexible surgical screwdriver into a tool capable of working with a significant angle offset. It is equipped with a Flohr ergonomic handle, recognized for improving comfort of use and the precision of the surgical gesture. The terminal part is configured to accommodate a universal hexagonal connector, guaranteeing extensive compatibility with current dental surgical instrumentation standards. The overall design aims to minimize bulk while maximizing the transmission of rotary movement.

What are the contraindications for the use of this screwdriver?

Although no specific medical contraindications are listed for this mechanical instrument, its use should be avoided in situations where the components to be screwed do not match the intended universal hexagonal format. Using excessive tightening torque exceeding the screw manufacturer's recommendations can lead to a failure of the cardan mechanism or damage to the screw head. It is also contraindicated to use this instrument if it shows marked signs of wear at the joint or the hexagonal connection, which could compromise the safety of the surgical act. The practitioner must ensure the perfect match between the instrument and the implant material used.

What are the maintenance and handling precautions?

As a non-resorbable instrument intended for repeated use after sterilization, the surgical cardan screwdriver requires rigorous maintenance. Particular attention must be paid to cleaning the cardan joint to remove any organic residue that could hinder the mobility of the articulation. It is recommended to check the integrity of the hexagonal connector before each intervention to prevent any slipping during screwing. Storage must be in a dry environment to preserve the mechanical properties of the steel used by Helmut Zepf Medizintechnik GmbH. Compliance with decontamination and steam sterilization cycles is imperative to guarantee asepsis during regeneration bone surgeries.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized player in the manufacture of high-precision dental surgical instrumentation. Regarding standards and certifications, although the regulatory class and CE marking are not explicitly detailed in the current source data, this product is manufactured according to the rigorous quality standards of the German industry. Practitioners are invited to systematically refer to the instructions for use and labeling provided with the product (reference 47.502.25) to verify current certifications and specific reprocessing instructions. Traceability is ensured by the Helmut Zepf catalog reference, guaranteeing the origin and compliance of the device with oral surgery requirements.
