What is the Obwegeser - Helmut Zepf (38.428.04) retractor?

The Obwegeser retractor, referenced under code 38.428.04, is a precision surgical instrument manufactured by Helmut Zepf Medizintechnik GmbH. Belonging to the category of retraction instruments (INSTRU), this device is designed to retract soft tissues to clear the intervention area. Its structure is adapted to the requirements of oral surgery, allowing for a firm hold without accidental slipping. As a Helmut Zepf product, this retractor benefits from the expertise of a manufacturer recognized in the field of medical instrumentation, guaranteeing a tool adapted to sterilization protocols and intensive use in dental offices or hospital environments.

What are the clinical indications for this instrument?

The Obwegeser retractor is primarily indicated for oral, maxillofacial, and implant surgery. Its role is crucial during procedures requiring wide and stable exposure of bone structures, such as osteotomies, complex extractions, or implant placement in difficult-to-access areas. By maintaining mucoperiosteal flaps or cheek tissues, it allows the practitioner to work with a clear view of the surgical site. This instrument is particularly useful for protecting soft tissues from rotating or sharp instruments during the surgical act, thus ensuring increased safety for the patient and optimized working ergonomics for the operator.

What are the technical characteristics of the 38.428.04 retractor?

The Helmut Zepf Obwegeser retractor is distinguished by its technical reference 38.428.04, which defines its specific dimensions and curvature. Although detailed material specifications are not listed in the source data, this type of Helmut Zepf instrument is designed to meet the constraints of oral surgery. Its shape is studied to adapt to facial anatomy, offering effective leverage for tissue retraction. The design of the instrument allows for a stable grip, reducing fatigue for the assistant or surgeon during prolonged interventions. Its finish is intended to minimize reflections under surgical lighting, thus preserving visual comfort during the operation.

What are the contraindications for the use of this retractor?

There are no specific medical contraindications documented in the provided sources for this instrument. However, as with any surgical device, its use is contraindicated in case of a known allergy to the metallic components of the instrument, although stainless steel is the standard for this category. The use of the Obwegeser retractor should be avoided if the surrounding tissues show extreme fragility or a pathology that does not allow for retraction pressure. The choice of instrument must always be validated by the practitioner based on the patient's specific anatomy and the nature of the planned intervention.

What are the maintenance and handling precautions?

The Obwegeser retractor is a non-absorbable and reusable instrument that requires a rigorous decontamination and sterilization protocol between each patient. After the intervention, it must be cleaned to remove any organic residue before being placed in an autoclave. It is recommended to follow the specific instructions from the manufacturer Helmut Zepf Medizintechnik GmbH to preserve the integrity of the instrument and avoid any corrosion. A visual inspection before each use is necessary to check for the absence of deformations or structural damage that could compromise the safety of the surgical gesture or injure the patient's tissues during retraction.

Who is the manufacturer and what standards are respected?

The retractor is manufactured by Helmut Zepf Medizintechnik GmbH, a manufacturer recognized worldwide for the quality of its surgical instrumentation. Regarding standards and certifications such as the regulatory class or CE marking, this information is not specified in the current technical data for this product. It is the practitioner's responsibility to refer to the instructions for use and the labeling of the delivered product to verify the certifications in force and compliance with the European Medical Device Regulation (MDR). Helmut Zepf ensures traceability via reference 38.428.04 to guarantee the origin and manufacturing quality of this oral surgery instrument.
