Cruciform slot surgical blade, 1.2 mm diameter, 15 mm length - Helmut Zepf (47.523.12) - Delynov

What is the Helmut Zepf cross-slot surgical blade?

The cross-slot surgical blade, referenced under code 47.523.12, is a precision instrument designed by Helmut Zepf Medizintechnik GmbH. This device is a specialized dental cross-slot bit, featuring a diameter of 1.2mm and a length of 15mm. Its structure is specifically developed to fit compatible screwdriver handles to facilitate the manipulation of small fixation components. As a technical consumable, this tool meets the requirements of modern oral surgery by providing a rigorous working interface between the practitioner and the osteosynthesis or implantology material. The manufacturing quality of the Helmut Zepf brand guarantees a constant tip geometry for professional use in clinics or hospital environments.

What are the clinical indications for this dental cross-slot bit?

This instrument is primarily indicated in oral surgery, periodontology, and implantology protocols requiring the use of fixation screws. It serves as a cross-slot screwdriver bit for the placement, tightening, or removal of micro-synthesis screws during bone grafts, membrane fixations, or bone blocks. Its thinness, with a diameter of 1.2mm, makes it particularly suitable for restricted access areas where visibility and precision of movement are critical. Dental surgeons and implantologists use this blade to ensure effective axial force transmission while limiting the risk of the tool slipping in the screw head, thus securing the mechanical stabilization steps of the grafts.

What are the technical characteristics of the 47.523.12 blade?

The Helmut Zepf cross-slot surgical blade features precise technical specifications to meet implantology needs. It has a working diameter of 1.2mm, allowing for exact insertion into the corresponding cross-slot sockets. Its total length of 15mm provides sufficient clearance to work comfortably without obstructing the operative visual field. Reference 47.523.12 defines a tip geometry optimized to reduce the cam-out effect, ensuring that the bit remains perfectly seated in the screw slot during the application of tightening torque. The design by Helmut Zepf Medizintechnik GmbH is based on a rigorous selection of materials to guarantee the necessary force transmission without premature deformation of the cross-slot.

What are the contraindications for the use of this instrument?

The use of this surgical blade is contraindicated in any situation where the component to be manipulated does not have a cross-slot socket strictly compatible with the 1.2mm diameter. The use of an unsuitable bit can lead to damage to the screw head or the instrument itself, compromising the success of the procedure. This device should also not be used in cases of known hypersensitivity to the metallic components of the constituent alloy, although it is selected for medical use. As with any surgical instrument, visible deformation of the tip or marked wear of the cross-slot constitutes a contraindication for its use, requiring immediate replacement of the blade to avoid any risk of intraoperative fracture or slippage.

What are the maintenance and durability precautions?

As a non-resorbable instrument intended for mechanical manipulation, this surgical cross-slot blade requires a strict decontamination and sterilization protocol between each use, in accordance with the manufacturer Helmut Zepf's guidelines. Although the category mentions CONSO, the durability of the bit directly depends on compliance with the recommended tightening torques and the absence of excessive lateral stress. It is recommended to systematically inspect the 1.2mm tip under magnification to detect any micro-cracks or blunting of the slot edges. Thorough cleaning to remove organic residues in the recesses of the cross-slot bit is essential before autoclaving to prevent corrosion and guarantee the functional longevity of the instrument.

Who is the manufacturer and what standards are respected?

The official manufacturer of this device is Helmut Zepf Medizintechnik GmbH, a recognized player in the field of high-precision surgical instrumentation. Based in Germany, this company applies rigorous manufacturing standards to its entire catalog. For the product referenced 47.523.12, information regarding the specific regulatory class and CE marking is not detailed in the current source documentation, but the manufacturer is renowned for its compliance with European quality requirements applicable to medical devices. Practitioners are invited to systematically refer to the instructions for use and the labeling of the delivered product to verify current certifications and specific reprocessing instructions for this cross-slot blade.
