Flat 4mm Wide Scissors - Helmut Zepf (47.949.21) - Delynov

What is the 4mm Helmut Zepf flat chisel?

The 4mm wide flat chisel, referenced under code 47.949.21 by Helmut Zepf, is a manual instrument designed for bone surgery. Manufactured from high-quality medical stainless steel, this bone chisel features a robust structure adapted to the constraints of clinical interventions. It belongs to the category of reusable consumables (CONSO) and is classified as a Class I medical device. This instrument is delivered non-sterile by the manufacturer Helmut Medizintechnik GmbH and requires a complete reprocessing protocol before each use to guarantee the safety of the patient and the practitioner.

What are the clinical indications?

This dental bone chisel is indicated for all oral surgery procedures requiring precise manipulation of bone tissues. Its primary use concerns the cutting, removal, or remodeling of alveolar bone. It is particularly requested during the preparation phases of implant sites, the regularization of bone ridges, or corrective osteotomies. As a manual instrument, it allows the dental surgeon or implantologist to exercise direct tactile control during the sectioning of hard structures, thus facilitating complex technical gestures in a restricted surgical environment.

What are the technical characteristics?

The Helmut Zepf flat chisel (47.949.21) is characterized by a flat working part with a width of 4mm. This specific dimension is ideal for interventions requiring an intermediate cutting footprint. The instrument is entirely designed in medical stainless steel, a material chosen for its corrosion resistance and its ability to withstand repeated sterilization cycles. In accordance with the guidelines of the manufacturer Helmut Zepf Medizintechnik GmbH, the product design and the materials used do not allow for a defined maximum limit of processing cycles, although the condition of the cutting edges must be inspected regularly.

What are the contraindications for use?

The main medical contraindication documented by the manufacturer concerns hypersensitivity or intolerance to metals. Contact with the medical stainless steel instrument can trigger a reaction in allergic patients. If such a hypersensitivity reaction occurs during the intervention, the procedure must be immediately stopped and the necessary medical measures must be taken. Furthermore, the use of this instrument is strictly reserved for qualified healthcare professionals. It must never be used if visible damage such as cracks, breaks, or defects on the cutting edges are noted during the preoperative inspection.

What are the maintenance and sterilization precautions?

Like any Helmut Zepf surgical instrument, this chisel must imperatively be cleaned, disinfected, and sterilized before the first use as well as after each subsequent use. The reprocessing process must be complete to ensure the elimination of any contaminant. It is crucial to check for the absence of wear or damage on the sharp edges before each intervention; the use of damaged products is prohibited. Given that the devices are delivered non-sterile, rigorous compliance with cleaning and autoclave sterilization protocols is a sine qua non condition for maintaining the integrity of the stainless steel and clinical safety.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is the company Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This flat chisel is a Class I instrument, compliant with regulatory requirements relating to manual medical devices. The manufacturer ensures the traceability and quality of its instruments through rigorous manufacturing processes. Although the specific CE marking is not detailed in the source data provided, the product meets the manufacturing standards for medical stainless steel dental instruments. The use of this instrument is exclusively reserved for healthcare professionals trained in oral surgery techniques.
