Bone scraper, 10mm diameter, 156mm length - Helmut Zepf (47.959.00) - Delynov

What is the Helmut Zepf 47.959.00 bone scraper?

The bone scraper referenced 47.959.00 is a manual surgical instrument designed by Helmut Zepf Medizintechnik GmbH. Manufactured from medical stainless steel, this tool is specifically structured for harvesting bone tissue. It features an ergonomic handle with a total length of 156mm, ending in a circular active part with a diameter of 10mm. As an autogenous bone collector, it allows the practitioner to recover bone chips mechanically. This device belongs to the category of reusable consumables, requiring a strict cleaning and sterilization protocol between each patient to ensure clinical safety.

What are the clinical indications for this manual bone harvester?

This instrument is indicated for all oral, periodontal, or implant surgery interventions requiring the supply of autogenous bone. The manual bone harvester is used to scrape the cortical surface of donor sites in order to collect bone fragments intended for grafts or the filling of bone defects. Its use is strictly reserved for qualified healthcare professionals. It is primarily used during the preparation of recipient sites before implant placement, thus optimizing the available bone volume by adding biological material harvested directly from the patient during the same operative phase.

What are the technical characteristics of this instrument?

The Helmut Zepf bone scraper features precise specifications to meet the requirements of fine surgery. Its 10mm diameter allows for effective action on flat or slightly concave bone surfaces. The 156mm length ensures a stable grip and facilitated access to different areas of the oral cavity. Designed in high-quality medical stainless steel, it is resistant to repeated decontamination cycles. This device is delivered non-sterile by Helmut Zepf Medizintechnik GmbH and must imperatively undergo complete processing (cleaning, disinfection, and sterilization) before its first use and after each subsequent use.

What are the contraindications for the use of this device?

The main medical contraindication lies in the patient's known intolerance or hypersensitivity to metals, particularly to the components of medical stainless steel. An allergic reaction may be triggered upon contact with the instrument. If such a hypersensitivity reaction occurs during the intervention, the procedure must be stopped immediately and necessary medical measures must be taken. Furthermore, it is strictly forbidden to use the instrument if it shows visible damage such as cracks, breaks, or defects on the cutting edges, as this could compromise patient safety and the effectiveness of the surgical procedure.

What are the maintenance and reprocessing precautions?

As a non-resorbable stainless steel instrument, its durability depends on the rigour of its maintenance. All instruments must be cleaned, disinfected, and sterilized before the first use and after each use. The manufacturer specifies that due to the design and materials used, there is no defined maximum limit for processing cycles, as long as the instrument does not show wear or damage. It is crucial to inspect the device before each intervention to detect any trace of corrosion or deformation. The use of damaged or worn products is prohibited to maintain tissue integrity during bone harvesting.

Who is the manufacturer and what standards are respected?

This bone scraper is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized company located in Seitingen-Oberflacht, Germany. The device is classified as a Class I instrument according to the current regulations on medical devices. Compliance with safety and performance requirements is ensured by the manufacturer, who imposes strict instructions for use and safety. The products are delivered non-sterile and must be reprocessed according to standard hospital protocols. Traceability is ensured by the technical reference 47.959.00, guaranteeing the origin and German manufacturing quality of the instrument.
