Instructions for Use
Aortic punch
Upon use of an alkaline cleaning agent and/or an acidic neutralizer, surfaces with metallic coating (e.g.
SolidBlack) and all titanium components can show material changes already after a short time. These are
mostly slightly gray or brown discolorations of the coated surface or fading of the anodized titanium. Based
on the current state of research, these do not interfere with the instruments' functionality.
For SolidBlack coatings, no hydrogen peroxide must be used. The material is best protected by use of pH-
neutral treatment agents.
Therefore, only neutral or mildly alkaline cleaning agents are permitted.

Control and Care
Following cleaning, the instruments must be macroscopically clean, i.e. free from visible dirt or deposits.
•
Check the instruments, and in particular their connections, for fractures, cracks, deformation, damage
and proper function.
Worn, corroded, deformed, porous or otherwise damaged instruments must be disposed of.
Alternatively, corresponding measures can be initiated (e.g. surface treatment), see also the
recommendations by the Instrument Processing Working Group (AKI):

•
If possible, re-assemble the instruments directly after cleaning.
•
Rotate the handle to return the aortic punch to the "punching" position.
Due to their alloy, stainless steel instruments typically develop a passive film in the form of a protective
layer. However, this film does not protect them well against chemical attack by chloride ions and aggressive
media and liquids!
Therefore, in addition to the instrument manufacturer's endeavors to select the right materials and process
them carefully, the user must make an important contribution by ensuring proper instrument processing
along with adequate and regular care.
5.6
Packaging
•
Use approved sterilization packaging (complying with EN 868/ISO 11607 requirements, for example)
for sterilization and subsequent transportation and storage.
