DRILL. INNER DIAMETER 6.0 MM - Helmut Zepf (08.910.08S) - Delynov

What is the Helmut Zepf 08.910.08S trephine?

The Helmut Zepf trephine, reference 08.910.08S, is a specialized rotary surgical instrument. This device features an inner diameter of 6.0 mm, designed specifically for bone surgery procedures. It belongs to the consumables (CONSO) category and is classified as a Class IIa medical device according to current regulations. Manufactured by Helmut Zepf Medizintechnik GmbH, this instrument is intended for strict professional use in surgical environments for the manipulation of hard jaw tissues.

What are the clinical indications for this instrument?

The intended use of the Helmut Zepf trephine covers two main clinical indications in oral and implant surgery. Firstly, it is used to create and harvest cylindrical bone blocks from the jaw. These harvests can be reused as-is at other surgical sites or introduced into a bone mill for subsequent treatment. Secondly, this instrument is indicated for the explantation of already integrated implants, allowing for a controlled removal of the implant and surrounding tissues if necessary.

What are the technical and handling characteristics?

The trephine has an internal diameter of 6.0 mm. To obtain bone blocks, the practitioner must attach the trephine to a contra-angle and set the motor between 800 rpm and its maximum speed. The drilling or milling process must be performed using continuous in-and-out movements. Abundant irrigation with sterile physiological saline solution is imperative, either manually or via the contra-angle's rinsing system. For explantation, the recommended speed is between 800 rpm and 1000 rpm maximum.

What are the contraindications for using this trephine?

Although the manufacturer Helmut Zepf Medizintechnik GmbH provides precise handling instructions, no specific medical contraindications are listed in the provided technical data, beyond limits related to processing cycles. Use is strictly reserved for qualified healthcare professionals. Failure to follow irrigation protocols or applying excessive pressure during drilling can pose a risk to the integrity of the tissues or the instrument itself.

What precautions should be taken during the procedure?

During use, excessive pressure must be avoided to prevent thermal or mechanical damage. It is crucial never to stop the motor while the trephine is inside the surgical cavity. Stopping the motor in an intraosseous position can prevent the removal of the instrument or cause it to break. Maintaining a constant flow of sterile physiological saline solution is mandatory to ensure the cooling of the surgical site and the instrument throughout the milling process.

Who is the manufacturer and what standards are met?

This device is manufactured by Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This recognized manufacturer complies with the requirements for Class IIa medical devices (MDC0483). Although the maximum number of processing cycles is not fixed, it is the responsibility of the healthcare professional to determine the end of the instrument's life based on its condition after each sterilization and use cycle, in accordance with the health facility's protocols.
