Abstract
A bone cutting surgical instrument includes features to mitigate heat generation during use. Excessive heat can be detrimental to bone health as well as to the instrument itself. In one example a liquid dispensing feature provides a flow of cooling liquid to an ultrasonic blade via a lumen in a waveguide of the instrument. In another example, the blade has a serrated edge with a plurality of teeth arranged in a pattern to provide dimension and space during cutting actions. In another example, the blade has an oversize distal portion that creates an oversize slot when cutting to avoid excessive contact between the cut bone and proximal portions of the blade. In another example the blade includes an irrigation slot and also a micro slot in a distal end of the blade that connects with the irrigation slot.
