TUNNELING KNIFE FIG. 1 - Helmut Zepf (24.751.525M) - Delynov

What is the FIG. 1 Helmut Zepf tunneling knife?

The FIG. 1 tunneling knife, referenced under code 24.751.525M, is a specialized manual instrument designed by Helmut Zepf Medizintechnik GmbH. This device is manufactured from medical stainless steel, a standard material for oral surgery instrumentation ensuring resistance to sterilization processes. It is presented as a tool specifically sharpened for interventions on periodontal soft tissues. As a periodontology instrument, its structure is adapted to the delicate manipulation of gingival tissues without compromising local vascularization. This product is delivered non-sterile and requires a full cycle of cleaning, disinfection, and sterilization before its first use in the practice or operating room.

What are the clinical indications for this instrument?

This periodontal plastic surgery knife is primarily indicated for the tunneling technique. This procedure is commonly employed in the treatment of gingival recessions and connective tissue grafts. The instrument allows the practitioner to create a space between the alveolar bone and the periosteum or gingiva, thus facilitating the insertion of grafts without vertical releasing incisions. Its use extends to any oral plastic surgery intervention requiring precise dissection of soft tissues in narrow anatomical areas. The use of this periodontology instrument is strictly reserved for qualified healthcare professionals mastering muco-gingival surgery protocols and the requirements of modern implantology.

What are the technical characteristics of the 24.751.525M knife?

The Helmut Zepf tunneling knife (ref. 24.751.525M) is distinguished by a blade geometry optimized for the separation of gingival tissues. Manufactured in medical stainless steel, it meets the mechanical durability requirements necessary for repetitive dissection movements. The manufacturer specifies that the design of the instrument does not allow for a maximum limit of processing cycles to be defined, although the condition of the cutting edges must be inspected before each use. It is imperative to check for the absence of cracks, breaks, or visible defects on the active parts. Its compatibility with other instruments on the surgical tray must be validated by the practitioner before the intervention.

What are the contraindications for the use of this knife?

The main contraindication mentioned by the manufacturer Helmut Zepf Medizintechnik GmbH concerns known hypersensitivity or intolerance to metals. As the instrument is composed of medical stainless steel, contact with the patient can trigger an allergic reaction in sensitive individuals. If a hypersensitivity reaction occurs during the surgical act, the procedure must be immediately interrupted and appropriate medical measures must be taken. Furthermore, the use of the instrument is prohibited if it shows visible damage such as cracks or excessive wear of the sharp edges, in order to avoid any risk of unintended tissue trauma or breakage of the active tip.

What are the maintenance and reprocessing precautions?

As the tunneling knife is delivered non-sterile, a rigorous reprocessing protocol is mandatory. All instruments must be cleaned, disinfected, and sterilized before the first use and after each subsequent use. Cleaning must be meticulous to remove all biological residues before the sterilization phase. It is essential to visually inspect the instrument to detect any degradation (cracks, breaks, or dulling of the blades). The use of a damaged instrument is strictly prohibited. Due to its stainless steel composition, cleaning and disinfection products compatible with this material should be used to avoid premature corrosion and guarantee the longevity of the periodontology instrumentation.

Who is the manufacturer and what standards are respected?

The device is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer located in Germany. This tunneling knife is classified as a Class I medical device according to current regulations. The manufacturer ensures the compliance of its products with safety and performance requirements for manual dental instruments. Although specific CE marking is not detailed in the source data, the product complies with German industrial manufacturing standards for stainless steel medical devices. Compliance with the instructions for use and safety provided by Helmut Zepf is essential to guarantee patient safety and clinical efficacy during periodontal plastic surgery procedures.
