Whale tail surgical retractor, size 2, width 35 mm - Helmut Zepf (37.448.35) - Delynov

What is the whale-tail type surgical retractor, size 2?

The whale-tail type surgical retractor, size 2, is a specialized manual instrument designed by Helmut Zepf for soft tissue retraction in oral surgery. This device is distinguished by its flared working part, reminiscent of the shape of a caudal fin, which gives it its characteristic name. With a width of 35mm, this instrument offers a significant contact surface, allowing flaps to be held securely without exerting excessive point pressure. It is primarily used to clear the practitioner's view during critical phases of the intervention, ensuring optimal visual and instrumental access to the surgical site.

What are the clinical indications for this wide surgical retractor?

The use of this wide surgical retractor is indicated in numerous oral, periodontal, and implant surgery procedures. It is particularly effective when performing full-thickness flaps where stable retraction of the periosteum is required. In implantology, it protects the surrounding soft tissues during drilling or the placement of filling materials. Its 35mm width makes it ideal for interventions on extended sectors, allowing retraction to be maintained over several dental sites simultaneously. It thus helps prevent accidental trauma to soft tissues by rotary instruments by keeping them out of the working area.

What are the technical characteristics of reference 37.448.35?

Technical reference 37.448.35 corresponds to a specific model within the Helmut Zepf catalog. Key features include a size 2 and a blade width of 35mm. This generous dimension is designed to maximize exposure of the surgical field while ensuring a stable grip for the assistant or surgeon. The design of the whale-tail retractor prioritizes the distribution of traction force over a wide tissue area. Although alloy details are not specified here, instruments from this manufacturer are recognized for their corrosion resistance and suitability for standard sterilization cycles in dental practices.

What are the contraindications for the use of this instrument?

There are no specific absolute medical contraindications to the use of this retractor, other than those related to any oral surgery intervention. However, its use must be adapted to the patient's anatomy; a width of 35mm may prove unsuitable in areas of restricted access or in patients with limited mouth opening. Excessive traction that could lead to tissue tears or prolonged ischemia of the flap should be avoided. As with any metallic instrument, use is contraindicated in patients with known hypersensitivity to the alloy components, in accordance with the general recommendations of the manufacturer Helmut Zepf Medizintechnik GmbH.

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

As a reusable and non-resorbable surgical instrument, this retractor must strictly follow a rigorous decontamination and sterilization protocol after each use. It is recommended to perform immediate pre-disinfectant cleaning to prevent the fixation of organic residues. The practitioner must regularly inspect the surface condition of the instrument to detect any signs of oxidation or deformation. Although robust, the 35mm working part must be protected from direct shocks with other sharp instruments during packaging. Compliance with the autoclave sterilization parameters recommended by the manufacturer is essential to maintain the integrity of the steel and ensure patient safety.

Who is the manufacturer and what standards are respected?

This instrument is manufactured by Helmut Zepf Medizintechnik GmbH, a recognized manufacturer in the high-precision dental instrumentation sector. The Helmut Zepf brand is synonymous with quality and technical expertise in the design of surgical devices. Although specific certifications (regulatory class or CE marking) are not detailed in the source data provided, this type of device is traditionally subject to the safety and performance requirements in force for reusable surgical instruments. For any precise information on regulatory compliance or applied ISO standards, it is advisable to systematically refer to the instructions for use and the original labeling provided by the manufacturer.
