Fluroplastic Piston / Stapese Piston

About Fluroplastic Piston / Stapese Piston

Fluoroplastic piston specifications vary by product but commonly include shaft diameters of 0.4 mm to 0.6 mm, lengths from 3.5 mm to 6 mm, and a biocompatible Teflon (PTFE) material. Key features often include "plastic memory" for secure closure, a conventional design for easy attachment to the incus, and the ability to be trimmed to a desired length. Some designs combine fluoroplastic with other materials, such as a platinum wire for enhanced functionality. 

         Material: The piston is made from a fluoroplastic, most commonly Polytetrafluoroethylene (PTFE) or Teflon. 

         Shaft Diameter: Available in sizes like 0.4 mm, 0.5 mm, and 0.6 mm. 

         Functional Length: The length can range from 3.5 mm to 6 mm and is often adjustable. 

         Biocompatibility: The material is biocompatible with biological tissues. 

Key Features

         "Plastic Memory": 

This feature helps the piston maintain its shape, ensuring a secure and reliable attachment to the incus. 

         Adjustable Length: 

The piston can be trimmed with a surgical instrument to achieve the precise length required for each patient. 

         Conventional Design: 

The standard design facilitates easy attachment to the long process of the incus during surgery. 

         Loop Memory: 

Some models also feature "loop memory" for precise placement and secure attachment. 

Considerations

         Combination Designs: 

Some pistons are a combination of materials, such as platinum and fluoroplastic, to combine their unique properties. 

         Radiodensity: 

Be aware that some fluoroplastic portions are non-radiopaque and not visible on CT scans, while others may be combined with radiodense materials like platinum. 

         Manufacturer Variations: 

Specifications can vary by manufacturer, so it's important to consult product-specific information from suppliers like EON Meditech, as seen in this Medzell product page. 

Precision Engineering for Otolaryngology

Designed specifically for use in ear surgeries, the Fluroplastic Piston offers dimensional accuracy up to 0.05 mm, ensuring a precise fit during middle ear reconstruction. Its lightweight, non-corrosive, and non-magnetic properties make the device reliable and safe for both the patient and the surgical environment.


Safe, Biocompatible, and Allergen-Free

The piston is manufactured from fluoroplastic, a material well-known for its biocompatibility and resistance to corrosion. With a smooth, non-porous surface, it helps reduce infection risk, and being nickel-free and latex-free, it caters to patients sensitive to common allergens.


Sterile and Convenient Packaging

Each piston is individually packed in a sterile blister pack to maintain product integrity until use. The product's sterilization-by either gamma radiation or ethylene oxide-ensures the highest safety standards for single-use applications, supporting effective hearing restoration procedures.
