Stainless Steel Meisinger Trephines (229 040) - Hager & Meisinger GmbH (3300229205040)

What is the Meisinger stainless steel trephine (229 040)?

The Meisinger brand stainless steel surgical trephine is a high-precision rotary instrument designed for the circular cutting of hard tissues. Manufactured by Hager & Meisinger GmbH, this tool is specifically developed to meet the requirements of oral surgery and implantology. Its stainless steel structure guarantees the necessary resistance during mechanical stresses related to bone drilling. This device is identified under technical reference 3300229205040 and is part of the range of surgical consumables for dental practices and specialized hospital centers. It allows for bone sampling or precision drilling with high trajectory stability.

What are the clinical indications for this dental stainless steel trephine?

The use of this dental stainless steel trephine is indicated in various maxillofacial surgery and implantology procedures. It is primarily used for harvesting autogenous bone grafts in the form of cylindrical cores, thus facilitating pre-implant bone reconstructions. This implant trephine drill is also useful for the excision of intraosseous lesions or for the surgical removal of osseointegrated implants when clinically necessary. According to the manufacturer Hager & Meisinger GmbH, the use of these devices presupposes adequate expertise and experience in diagnosis, preoperative planning, and surgical techniques specific to implantology or maxillary surgery.

What are the technical characteristics of this instrument?

This stainless steel surgical trephine is characterized by its monobloc or assembled design according to Meisinger standards, offering optimal concentricity to avoid vibrations during drilling. As a Class IIa device, it meets strict safety and performance standards. Its cutting geometry is designed to ensure efficient evacuation of bone chips while limiting thermal heating of surrounding tissues. Reference 3300229205040 ensures precise product traceability. It is imperative that the user has the required knowledge to adapt the rotation speed and irrigation according to the bone density encountered during the procedure.

What are the contraindications for the use of this device?

Although the raw MDR text does not list specific medical contraindications related to systemic pathologies, the use of this surgical stainless steel trephine is strictly reserved for qualified practitioners. A major contraindication lies in the non-compliant use of the device, which can lead to premature wear and involve risks for patients and users. The physician must decide, under their sole responsibility, on the use of Meisinger devices on a case-by-case basis, depending on the patient's particular clinical situation. Insufficient training or lack of knowledge of surgical drilling techniques constitute de facto contraindications to the handling of this rotary instrument.

What are the precautions for use and maintenance?

To guarantee the safety of care, any non-compliant use of the trephine must be prohibited. Inappropriate use can compromise the integrity of the instrument and patient safety. The manufacturer Hager & Meisinger GmbH emphasizes that any serious incident occurring in connection with the device must be immediately notified to the manufacturer and the competent authority of the Member State. Practitioners are encouraged to refer to the manufacturer's catalog for detailed specifications and to follow regularly offered continuing education sessions. Maintenance must follow standard sterilization and cleaning protocols for Class IIa stainless steel rotary instruments to maintain their cutting properties.

Who is the manufacturer and what standards are respected?

The trephine is manufactured by Hager & Meisinger GmbH, a company based in Neuss, Germany, recognized for its expertise in medical rotary instruments. This medical device is certified Class IIa and bears the CE0044 marking, attesting to its compliance with current European regulatory requirements. The Meisinger brand ensures that all its devices have been developed for specific use, thus guaranteeing high reliability when handled by trained specialists (dentists, maxillary surgeons, or specialized physicians). For more information on applications and training related to these devices, the manufacturer provides resources on its official website.
