Ramus 22 cm Spreader - Helmut Zepf (38.428.22) - Delynov

What is the 22 cm Helmut Zepf Ramus retractor?

The 22 cm Ramus retractor, referenced under code 38.428.22 by Helmut Zepf, is a manual surgical instrument designed for tissue exposure. Manufactured from high-quality medical stainless steel, this robust device is intended to keep the incision edges separated, thereby providing increased visibility of the operative site. Its structure is specifically adapted to the anatomical constraints of the mandibular zone. As a Class I device, it meets safety requirements for non-invasive or transiently invasive instruments. This equipment is delivered non-sterile and requires a complete decontamination protocol before its first use in the dental office or operating theater.

What are the clinical indications for this maxillofacial surgery retractor?

This Ramus retractor is primarily indicated for maintaining the surgical area open during invasive procedures. In maxillofacial surgery, it is used to retract soft tissues and expose the ascending ramus of the mandible. Its use is essential during osteotomies, facial trauma management, or reconstructive surgery where direct and stable visual access is required. The instrument allows the practitioner to work safely by avoiding inappropriate tissue compression while ensuring a clear field for rotating or cutting instrumentation. Its use is strictly reserved for qualified healthcare professionals proficient in tissue retraction techniques.

What are the technical characteristics of instrument 38.428.22?

The Helmut Zepf retractor has a total length of 22 cm, a dimension optimized to provide sufficient leverage and a stable grip during deep retractions. It is entirely designed in medical stainless steel, a material chosen for its corrosion resistance and its ability to undergo repeated sterilization cycles. The instrument design takes into account the need to minimize trauma to the retracted tissues. No electronic components or consumables are associated with this technical reference. Its surface finish is developed to limit reflections under scialytic lighting, thus improving the surgeon's visual comfort during critical phases of the procedure.

What are the contraindications for the use of this instrument?

The main medical contraindication mentioned by the manufacturer Helmut Zepf Medizintechnik GmbH concerns the patient's known hypersensitivity to metals. Contact between the medical stainless steel instrument and a patient with an intolerance can trigger a hypersensitivity reaction. If such a reaction occurs during the procedure, the procedure must be stopped immediately and appropriate clinical measures must be initiated. Furthermore, the use of the instrument is prohibited if visible damage or wear is detected, such as cracks, breaks, or defects on the edges. Using a damaged product would compromise patient safety and the effectiveness of the surgical retraction.

What are the maintenance and reprocessing precautions?

Like all instruments in the Helmut Zepf range, this retractor is delivered non-sterile. It is imperative to perform complete cleaning, disinfection, and sterilization before the first use, as well as after each subsequent use. The manufacturer emphasizes the critical importance of checking the condition of the instrument before each intervention to identify any signs of wear. Due to its robust design and the materials used, there is no defined maximum limit for the number of treatment cycles, as long as the physical integrity of the steel is preserved. Strict compliance with reprocessing protocols guarantees not only the sterility of the device but also its functional longevity within the surgical arsenal.

Who is the manufacturer and what standards are respected?

This instrument is manufactured by Helmut Zepf Medizintechnik GmbH, a company located in Seitingen-Oberflacht, Germany, recognized for its expertise in surgical instrumentation. The product is classified as a Class I medical device, in accordance with current regulations. The manufacturer ensures traceability and production quality through strict control processes. It is reminded that the use of this retractor is strictly reserved for healthcare professionals. Compatibility with other products used simultaneously during surgery must be verified beforehand by the user to ensure total operative safety.
