What are the technical characteristics of this instrument?

The Helmut Zepf 47.949.11 chisel is characterized by a 4mm working width with a pointed end. Manufactured in medical stainless steel, it is designed to withstand repeated reprocessing cycles. The manufacturer specifies that due to the product design and materials used, there is no defined maximum limit for the number of sterilization cycles, although the instrument must be visually inspected before each use. It is imperative to check for the absence of cracks, breaks, or defects on the cutting edges to ensure operative safety.

What are the contraindications for the use of this device?

The main medical contraindication mentioned by Helmut Zepf Medizintechnik GmbH concerns hypersensitivity or intolerance to metals. Contact with medical stainless steel 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 the instrument is prohibited if visible damage, such as cracks or excessive wear of the sharp edges, is detected during the preoperative check.

What are the maintenance and reprocessing precautions?

As the product is delivered non-sterile, a rigorous cleaning and sterilization protocol is mandatory before the first use. Before each subsequent use, the chisel must be fully cleaned, disinfected, and sterilized. The practitioner must ensure compatibility with other products used during the reprocessing cycle. Visual inspection is a critical step: never use damaged products or those with defects on the cutting edges. Although no cycle limit is set, the natural wear of materials can alter cutting performance over time.
