Ultrasonic cutting blade with cooling liquid conduction

A surgical method comprising:

• providing an ultrasonic surgical tool having a probe body and a shank connected at a proximal end thereof, said probe body having an operative surface or edge, said shank and said probe body being formed with a channel, at least a portion of said probe body extending between said channel and said operative surface or edge having a microporous structure;
• operatively connecting a proximal end of said shank to a source of ultrasonic mechanical vibrations;
• operatively coupling said channel to a source of liquid;
• moving said probe body to a surgical site on a patient;
• placing said operative surface or edge in contact with organic tissues at said surgical site;
• while said operative surface or edge is in contact with the organic tissues, generating ultrasonic mechanical vibrations in said probe body, thereby ultrasonically vibrating said operative surface or edge;
• while said operative surface or edge is in contact with the organic tissues and during the generating of the ultrasonic mechanical vibrations in said probe body, feeding liquid under pressure from said source of liquid into said channel and from said channel through multiple micropore pathways in said probe body to said operative surface or edge.

A surgical method comprising:

• providing an ultrasonic surgical tool having a probe body and a shank connected at a proximal end thereof, said probe body having an operative surface or edge, said shank and said probe body being formed with a channel, said probe body having a multiplicity of micropore or microchannel pathways extending from said channel to said operative surface or edge, said probe body being devoid of other pathways for liquid flow from said channel to said operative surface or edge;
• placing said operative surface or edge in contact with organic tissues at a surgical site on a patient;
• while said operative surface or edge is in contact with the organic tissues, generating ultrasonic mechanical vibrations in said probe body, thereby ultrasonically vibrating said operative surface or edge;
• while said operative surface or edge is in contact with the organic tissues and during the generating of the ultrasonic mechanical vibrations in said probe body, flowing liquid under pressure through said channel and from said channel through said micropore or microchannel pathways in said probe body to said operative surface or edge.
