Surgical mucosal trephine, internal diameter 6.5mm - Helmut Zepf (08.920.16) - Delynov

What is the Helmut Zepf surgical mucosal trephine?

The Helmut Zepf surgical mucosal trephine is a high-precision rotary instrument designed specifically for cutting soft tissues in oral surgery. Identified under reference 08.920.16, this device features a sharpened tubular structure allowing for clean circular incisions. Its design by the manufacturer Helmut Zepf Medizintechnik GmbH guarantees a tool adapted to the requirements of dental operating theaters. This type of instrument, often called a circular scalpel, is essential for obtaining constant and reproducible cutting diameters, thus minimizing irregularities during mucosal excision or tissue harvesting.

What are the clinical indications for this mucosal trephine?

This surgical mucosal trephine is indicated in various oral and implant surgery procedures. It is primarily used for the mucosal 'punch' technique, allowing for the exposure of a submerged implant head without a large flap, or to prepare the site before placing a healing abutment. In periodontology, it can be used for harvesting gingival plugs for soft tissue grafts. Its use is also relevant for the excision of small benign lesions of the oral mucosa requiring a clean circular section border. The use of this rotary mucotome must be performed by a practitioner trained in oral surgery techniques.

What are the technical characteristics of model 08.920.16?

The Helmut Zepf trephine reference 08.920.16 is characterized by an internal diameter of 6.5 mm. This specific dimension allows for precise calibration of the incision according to the diameter of the implant components or the desired sampling area. The instrument is designed to be mounted on a rotary handpiece, allowing for rapid and regular cutting. The geometry of the circular blade is optimized to penetrate the mucosa with controlled resistance. As a Helmut Zepf product, this instrument benefits from the German manufacturer's expertise in rotary instrumentation, ensuring the concentricity essential to avoid any harmful vibration during the surgical act.

What are the contraindications for the use of this device?

The contraindications for the use of this dental surgical trephine are related to the patient's general clinical conditions and the specificities of the surgical site. Its use is contraindicated in cases of insufficient mucosal thickness or immediate proximity to sensitive anatomical structures (nerves, major vessels) without adequate visual control. Furthermore, as with any surgical rotary instrument, its use is prohibited in patients with unstabilized coagulation disorders or local bone pathologies contraindicating surgery. Reference should systematically be made to the instructions for use from the manufacturer Helmut Zepf Medizintechnik GmbH to review specific warnings.

What are the maintenance and durability precautions?

As a rotary cutting instrument, maintaining sharpness is crucial for patient safety and the efficiency of the procedure. The practitioner must visually inspect the cutting edge of the trephine before each use to detect any signs of wear, chipping, or deformation. A dull instrument increases the risk of tissue overheating and mucosal tearing. Although sterilization protocols depend on the nature of the material, it is imperative to follow the cleaning and decontamination cycles recommended by Helmut Zepf for rotary instruments to prevent corrosion and ensure asepsis. Compliance with the recommended rotation speed parameters is also essential for the tool's longevity.

Who is the manufacturer and what are the quality guarantees?

The trephine is manufactured by Helmut Zepf Medizintechnik GmbH, a German company globally recognized for its expertise in the design of dental and surgical instruments. Helmut Zepf applies rigorous manufacturing standards to ensure the compliance of its products with medical sector requirements. Although the specific regulatory class and CE marking are not detailed here, this brand's products are developed according to strict quality control processes.
