"Evacuation" refers to the process of removing bone debris, bone chips, and/or other particulate material from the cutting face and/or one or more sets of rasp features of a surgical tool during operation. Evacuation may occur through passive or active mechanisms to enhance cutting efficiency, maintain clear visibility, and reduce heat buildup or clogging.
In certain embodiments, evacuation may be facilitated by tooth or rasp feature geometry, including gullet spacing, openings, serrations, or fluting, which directs bone debris away from the cutting face; oscillatory or reciprocating motion, which aids in self-clearing of bone material from engagement surfaces; integrated fluid irrigation systems, such as saline or cooling agents, which assist in flushing debris from the cutting interface; vacuum-assisted suction mechanisms, which actively remove bone particles from the cutting region; openings, ports, or channels specifically designed and/or configured to facilitate evacuation, which may include apertures and/or openings within a blade or a foot or a cutting face, fenestrations in the rasp surface, or grooves along the cutting edge to promote continuous removal of debris.
As used herein, "evacuation" encompasses any mechanism or structural design feature that promotes the removal, displacement, or clearing of bone debris from the cutting face or rasp features, whether by mechanical action, fluid assistance, suction, or integrated openings configured for debris management.
