Abstract
An ultrasonic surgical tool has probe body with an operative surface or edge contactable with organic tissues for performing a surgical operation on the tissues. A shank of the probe body is provided with a connector for operatively attaching the tool to a source of ultrasonic mechanical vibrational energy. The shank and a portion of the probe body are formed with a channel for fluid delivery to the probe body. At least a portion of the probe body located between the channel and the operative surface or edge has a microporous or sintered structure enabling fluid penetration to the operative surface or edge from the channel.
