Cable tractor for BENEX 48mm extractor - Helmut Zepf (12.300.22) - Delynov

What is the cable tractor for the BENEX 48mm extractor?

The cable tractor for the BENEX 48mm extractor, referenced under code 12.300.22, is a crucial replacement component for the Benex extraction system designed by Helmut Zepf. This dental extractor part ensures the necessary mechanical transmission between the extractor carriage and the screw inserted into the root. Its specific design allows it to withstand the axial traction forces required during oral surgery procedures aimed at extracting roots or root fragments. As a root extractor spare part, it guarantees the operational continuity of the original Benex kit.

What are the clinical indications for this device?

The use of this cable tractor is intended for the controlled extraction of single-rooted roots or root fragments. It is particularly indicated when preserving the integrity of soft tissues and surrounding alveolar structures is a clinical priority. This device is also used for extrusion, which corresponds to the atraumatic repositioning of a root out of its socket for subsequent fixation by splinting. In the case of multi-rooted teeth, the manufacturer Helmut Zepf specifies that the roots must be previously separated before proceeding with the individual extraction of each fragment.

What are the technical characteristics of this replacement part?

This replacement part for dental extractors has a length of 48mm, adapted to the Benex extractor mechanism. It is designed to be hooked on one side to the extraction screw (long or short) and on the other to the hook of the extractor carriage, after passing over a deflection pulley. This Benex cable tractor is manufactured by Helmut Zepf Medizintechnik GmbH, complying with the quality standards required for Class I devices. Its structure is designed to resist axial traction stresses without excessive deformation, allowing for a smooth and straight root exit movement.

What are the contraindications for using this extraction system?

Although the technical text does not list absolute medical contraindications related to the material, the use of the Benex system imposes strict clinical conditions. Extraction should not be attempted on multi-rooted teeth without prior root separation. Additionally, the protocol requires adequate anesthesia and rigorous site preparation, including the sectioning of periodontal fibers in the sulcus using a periotome. Failure to respect the drilling axis (approximately 7 mm deep) or the absence of prior axial mobilization for long roots may compromise the success of the procedure.

What are the precautions for use and maintenance?

This device is exclusively reserved for healthcare professionals. To ensure safety, root drilling must be performed with a diamond-coated twist drill under water cooling, at a recommended speed of 500 to 700 r.p.m. The cable tractor must be correctly positioned on the deflection pulley to avoid any abnormal friction. Regarding maintenance, although there is no defined maximum limit for processing cycles, the practitioner must regularly inspect the condition of the cable to detect any signs of wear or mechanical fatigue before each surgical intervention.

Who is the manufacturer and what standards are met?

The cable tractor for the BENEX extractor is manufactured by Helmut Zepf Medizintechnik GmbH, located in Seitingen-Oberflacht, Germany. This medical device belongs to Class I according to current regulations. As a recognized manufacturer in high-precision dental instrumentation, Helmut Zepf guarantees that this root extractor part meets the performance requirements for atraumatic extraction procedures. Compliance with cleaning and sterilization protocols by the healthcare professional is essential to maintain the device's conformity during use in private practices or hospital environments.
