Sinus lift elevator, double-ended, Ho-Hi model - Helmut Zepf (41.854.23) - Delynov

What is the Helmut Zepf Ho-Hi double sinus lift elevator?

The double sinus lift elevator, Ho-Hi model, is a specialized manual instrument developed by Helmut Zepf Medizintechnik GmbH for oral and implant surgery. This device is characterized by a double configuration, offering two distinct ends to assist the practitioner during the different phases of sinus elevation. As a double sinus lift instrument, it is designed to meet the requirements for handling delicate tissues within the sinus cavity. Its design by Helmut Zepf ensures a tool adapted to the rigorous clinical protocols of modern implantology, allowing for a structured approach during the preparation of the recipient site before grafting.

What are the clinical indications for this instrument?

The double sinus elevator is primarily indicated in pre-implant surgery procedures aimed at increasing vertical bone volume in the posterior maxilla. Its use is central during the sinus lift technique (sinus floor elevation) via lateral or crestal approaches, depending on the chosen protocol. This double sinus lift elevator allows for the precise detachment of the sinus membrane from the internal bone wall to create a secure space for the introduction of the bone substitute. It is used by dental surgeons and implantologists to ensure the continuity of the Schneiderian membrane while maximizing visibility and access during the intervention.

What are the technical characteristics of the Ho-Hi 41.854.23 elevator?

The instrument referenced under code 41.854.23 by Helmut Zepf features characteristics specific to the Ho-Hi range. It is a double sinus lift instrument equipped with two working parts optimized for membrane detachment. Although detailed material specifications are not explicitly listed, this type of Helmut Zepf device is designed to meet the requirements of sterilization and repeated surgical use. The double configuration allows for varying approach angles without changing instruments, thus optimizing the workflow during sinus elevation. Its geometry is studied to adapt to the complex anatomy of the maxillary sinus.

What are the contraindications for the use of this elevator?

The contraindications for using this double sinus lift elevator are primarily related to the general contraindications of sinus grafting surgery. These include acute sinusitis, local tumor pathologies, or untreated infections in the maxillary area. Technically, the use of the instrument is contraindicated if the sinus membrane has pre-existing major perforations that do not allow for elevation, or if the patient's anatomy does not permit secure access. Clinical protocols in force and the instructions for use from the manufacturer Helmut Zepf Medizintechnik GmbH should systematically be referred to in order to identify any specific restrictions related to the device.

What are the maintenance precautions for this implant surgery instrument?

Like any precision implant surgery instrument, the Ho-Hi double sinus elevator requires a strict decontamination and sterilization protocol after each use. It is imperative to follow the recommendations of the manufacturer Helmut Zepf regarding autoclave cycles and compatible cleaning products to preserve the integrity of the working parts. A visual inspection before each intervention is necessary to check for the absence of corrosion or deformation of the ends. Careful handling is recommended to avoid any damage to the fine edges of the instrument, thus ensuring the safety of the sinus membrane during subsequent interventions.

Who is the manufacturer and what is the regulatory information?

The official manufacturer of this instrument is Helmut Zepf Medizintechnik GmbH, a company recognized for producing high-quality surgical instrumentation. The product is identified under the technical reference 41.854.23. Regarding regulatory aspects such as risk class or specific CE marking, this information is not detailed in the current source documentation. Practitioners are invited to consult the product labeling and the instruction manual provided by Helmut Zepf to confirm compliance with current standards and specific safety instructions for the medical device before any use in the practice.
