Cleveland Bone Gouge Forceps 17cm, Fig. 4-A model - Helmut Zepf (42.334.17) - Delynov

What is the Helmut Zepf Cleveland bone rongeur?

The 17 cm Cleveland bone rongeur, model Fig. 4-A, is a high-precision manual instrument manufactured by Helmut Zepf Medizintechnik GmbH. Designed specifically for bone surgery and guided bone regeneration (GBR), it is crafted from medical-grade stainless steel. This instrument is distinguished by its robustness and its ability to act on hard tissues with great efficiency. As a Class I device, it meets the regulatory requirements for reusable surgical instruments. Its ergonomic structure allows for controlled handling during delicate interventions in dental practices or hospital settings, ensuring consistent performance for the practitioner.

What are the clinical indications for this instrument?

The intended use of this Helmut Zepf manual dental instrument primarily concerns the modification of bone structures. In oral and implant surgery, the Cleveland bone rongeur is indicated for the resection of bone splinters, the removal of exostoses, and the smoothing of alveolar ridges (alveoloplasty) after multiple extractions or prior to implant placement. It is also used in guided bone regeneration protocols to prepare the surgical site. Its clean cutting action allows for precise bone shaping, thereby promoting optimal soft tissue healing on a smooth bone base free of traumatic irregularities.

What are the technical characteristics of the 42.334.17 forceps?

The Helmut Zepf Cleveland bone rongeur, referenced under code 42.334.17, has a total length of 17 cm. This dimension provides an optimal lever arm for interventions requiring controlled cutting force on bone tissue. Manufactured from medical stainless steel, it is designed to withstand repeated cleaning and sterilization cycles. The Fig. 4-A model is specifically configured to access different areas of the oral cavity. The instrument is delivered non-sterile and must undergo a full decontamination protocol before its first use and between each patient, in accordance with the instructions from the manufacturer Helmut Zepf Medizintechnik GmbH.

What are the contraindications for the use of this instrument?

The main medical contraindication mentioned by the manufacturer Helmut Zepf concerns known hypersensitivity or metal intolerance in the patient. Since the instrument is composed of medical stainless steel, contact may trigger an allergic reaction in sensitive subjects. If such a hypersensitivity reaction occurs during the procedure, the intervention must be immediately interrupted and appropriate medical measures must be initiated. Furthermore, the use of the instrument is strictly reserved for qualified healthcare professionals. It is also contraindicated to use the device if it shows visible damage, such as cracks, breaks, or defects on the cutting edges, to ensure patient safety.

What are the maintenance and reprocessing precautions?

The Cleveland bone rongeur is a reusable device that requires rigorous maintenance. Before the first use and after each surgical procedure, the instrument must be cleaned, disinfected, and sterilized according to a complete protocol. It is crucial to visually inspect the product for any wear or damage before each use; never use damaged products. Due to the design of the instrument and the materials used by Helmut Zepf, there is no defined maximum limit for the number of processing cycles, as long as functional integrity is preserved. Compatibility with other cleaning and sterilization products must be verified beforehand to avoid any premature degradation of the stainless steel.

Who is the manufacturer and what standards are respected?

This medical device is manufactured by Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. The manufacturer is recognized for its expertise in the production of high-quality dental instruments. The 17 cm Cleveland bone rongeur is classified as a Class I medical device according to current regulations.
