Fluroplastic Piston / Stapese Piston

Product Description

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.
