Surgical punch forceps, inner ring 4mm, outer ring 9mm, depth 3mm - Helmut Zepf (08.922.02) - Delynov

What is the Helmut Zepf surgical biopsy punch?

The surgical biopsy punch, referenced under code 08.922.02 by Helmut Zepf Medizintechnik GmbH, is a specialized manual instrument for oral surgery. Its structure is distinguished by a cutting head composed of a 4 mm inner ring and a 9 mm outer ring. This instrument is specifically developed for the harvesting stages in guided bone regeneration (GBR) protocols. Its design allows for rigorous manipulation to obtain tissue samples with constant geometry, meeting the requirements of practitioners during tissue reconstruction phases.

What are the clinical indications for this instrument?

This dental biopsy punch is primarily indicated for harvesting epithelial-connective or pure connective tissue grafts. In implant and periodontal surgery, it is used to collect soft tissues intended to increase gingival volume or cover extraction sites. The use of a graft harvesting punch of this type is common during GBR procedures where the quality and shape of the harvested tissue determine the success of healing and final aesthetic integration. It allows intervention on various donor sites, notably at the palate or tuberosity, according to the patient's clinical needs.

What are the technical characteristics of the 08.922.02 forceps?

The technical specifications of this Helmut Zepf model include a fixed cutting depth of 3 mm, ensuring a controlled harvesting thickness. The inner ring diameter is 4 mm, while the outer diameter is 9 mm. These precise dimensions offer the surgeon optimal visibility of the working area while ensuring a clean cut. The instrument is designed to withstand the constraints of repeated sterilization in hospital or private practice environments. Its articulated mechanics allow for smooth force transmission, essential for a high-performance soft tissue harvesting punch during repetitive movements.

What are the contraindications for the use of this biopsy punch?

The contraindications for the use of this surgical biopsy punch are related to the physiological limits of the donor site and the patient's general health status. It must not be used if the mucosal thickness at the harvesting site is insufficient (less than the 3 mm depth of the instrument) to avoid any injury to underlying structures, such as palatal neurovascular bundles. Furthermore, as with any surgical instrument, its use is contraindicated in patients with uncontrolled bleeding disorders or severe systemic pathologies preventing any invasive intervention in the oral area.

What are the maintenance precautions for this non-resorbable instrument?

As a reusable steel surgical instrument, the tissue harvesting punch must follow a strict protocol of decontamination, cleaning, and sterilization after each use. It is recommended to use neutral pH cleaning solutions to preserve the integrity of the surfaces and the cutting edges of the 4 mm and 9 mm rings. A visual inspection of the cutting jaws is essential to ensure the absence of organic residues or corrosion. Regularly lubricating the joint of the forceps helps maintain the flexibility of the mechanism. Compliance with the autoclave cycles recommended by the manufacturer Helmut Zepf is essential to guarantee patient safety and tool longevity.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized player in the manufacture of high-precision surgical instrumentation based in Germany. Although the specific regulatory class and CE marking are not detailed in the current technical sheet, Helmut Zepf products are designed according to the rigorous quality standards of the European medical industry. Practitioners are invited to consult the instructions for use provided with instrument 08.922.02 to verify current certifications and specific safety instructions.
