Elevator Universal Sinus Lift - Helmut Zepf (41.822.04) - Delynov

What is the Stiller universal sinus elevator?

The Stiller (reference 41.822.04) is a manual dental instrument developed by Helmut Zepf Medizintechnik GmbH. It is manufactured from high-quality medical stainless steel, ensuring its resistance to thermal and chemical reprocessing. As a universal sinus elevator, its structure is specifically designed to meet the requirements of oral surgery during the access phases to the maxillary sinus. This device belongs to Class I of medical devices, confirming its compliance with regulatory requirements for non-invasive or short-term invasive instruments used in clinical practice by healthcare professionals.

What are the clinical indications for this Helmut Zepf instrument?

The Helmut Zepf sinus surgery instrumentation is indicated for pre-implant surgery procedures in the posterior maxilla. Its primary use concerns the elevation of the Schneiderian membrane (sinus lift). It is used by dental surgeons and implantologists to gently detach the mucous membrane from the internal bony wall of the sinus without causing perforation. This universal sinus elevator is suitable for both lateral window approaches and implant site preparation techniques requiring precise management of the sub-sinus space before the addition of bone substitutes.

What are the technical characteristics of the Stiller 41.822.04 elevator?

The Stiller universal sinus elevator, bearing technical reference 41.822.04, is distinguished by its medical stainless steel design. This material is chosen for its biocompatibility and its ability to withstand repeated cycles of cleaning, disinfection, and sterilization. As a Class I instrument, it meets the manufacturing standards of Helmut Zepf Medizintechnik GmbH. Its universal geometry allows for ergonomic handling during complex sinus surgery procedures. The manufacturer specifies that the instrument is delivered non-sterile and must undergo a complete sterilization protocol before its first use and between each patient.

What are the contraindications for the use of this instrument?

The main contraindication mentioned by the manufacturer Helmut Zepf concerns known hypersensitivity or intolerance to metals. Since the instrument is composed of medical stainless steel, contact with the patient may trigger a hypersensitivity reaction in sensitive subjects. If such a 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 strictly contraindicated if it shows visible damage, such as cracks, breaks, or defects on the cutting edges, to guarantee patient safety and the integrity of the manipulated tissues.

What are the maintenance and reprocessing precautions?

To ensure the longevity of this universal sinus elevator, all instruments must be cleaned, disinfected, and sterilized before the first use and after each subsequent use. It is crucial to visually inspect the device for any wear or damage before each procedure. Due to the robust design and materials used by Helmut Zepf, there is no defined maximum limit for the number of treatment cycles, as long as the instrument does not show functional degradation. The use of damaged or worn products is formally prohibited. This device is exclusively reserved for healthcare professionals trained in sinus surgery techniques.

Who is the manufacturer and what standards are respected?

This instrument is manufactured by Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. The manufacturer is recognized for its expertise in the production of precision surgical instrumentation. The product is listed as a Class I medical device (Class Ir according to certain reprocessing nomenclatures). It complies with the medical device directives for use as a manual dental instrument. Compliance with cleaning and sterilization protocols is the responsibility of the practitioner, in accordance with the instructions provided by Helmut Zepf to ensure clinical safety and the performance of the instrumentation during sinus surgeries.
