1x Stainless Steel Trephine - Meisinger - Hager & Meisinger GmbH (330229L205055)

What is the Meisinger stainless steel trephine?

The Meisinger stainless steel trephine is a precision rotary instrument manufactured by Hager & Meisinger GmbH. Designed specifically for bone surgery, this tool is made of high-quality stainless steel, ensuring optimal resistance during cutting. Its hollow cylindrical structure allows for precise circular osteotomies, facilitating the harvesting of bone grafts or the creation of specific sites. This device is a key element for practitioners performing oral surgery procedures requiring rigorous handling of hard tissues.

What are the clinical indications for this instrument?

In oral surgery and implantology, the Meisinger trephine is primarily indicated for harvesting autogenous bone cores, often used in alveolar reconstruction techniques. It is also employed for the excision of bone fragments or during the removal of osseointegrated dental implants that cannot be removed by conventional methods. This implantology trephine allows for a controlled surgical approach, limiting peripheral bone loss while ensuring a stable and predictable cutting trajectory for the dentist or oral and maxillofacial surgeon.

What are the technical characteristics of the trephine reference 330229L205055?

The Meisinger trephine with technical reference 330229L205055 is distinguished by its stainless steel construction, a material selected for its mechanical properties and corrosion resistance. Although specific dimensions are not detailed in the source data, this type of instrument is designed to fit standard surgical handpieces. Its geometry is optimized to minimize thermal heating during rotation while maintaining an effective cutting edge to pass through the various bone densities encountered in daily clinical practice.

What are the contraindications for the use of this device?

Contraindications for the use of the Meisinger stainless steel trephine are related to the general limits of rotary bone surgery. Its use is discouraged in patients with serious systemic pathologies affecting bone healing or in cases of insufficient bone density to support the instrument's action. Additionally, any known hypersensitivity to stainless steel components must be taken into account before the intervention. It is the practitioner's responsibility to evaluate the benefit-risk ratio based on local anatomy, particularly the proximity of critical nerve or sinus structures.

What are the maintenance and durability precautions?

Like any stainless steel rotary instrument intended for surgery, the Meisinger trephine must undergo a rigorous cleaning, disinfection, and sterilization protocol after each use, in accordance with the instructions from the manufacturer Hager & Meisinger GmbH. To maintain cutting efficiency and prevent any risk of cross-contamination, it is essential to check the condition of the cutting edges before each intervention. The use of abundant irrigation during drilling is imperative to avoid thermal necrosis of the surrounding bone and preserve the integrity of the instrument over the long term.

Who is the manufacturer and what standards are met?

This medical device is manufactured by Hager & Meisinger GmbH, a manufacturer recognized worldwide for its expertise in dental and surgical rotary instruments. The Meisinger brand is synonymous with German industrial rigor. Although the specific regulatory class and CE marking are not explicitly mentioned in the technical data provided for this reference 330229L205055, the product is designed according to the company's high quality standards. Practitioners are invited to refer to the instructions for use and official labeling to confirm applicable certifications.
