Abstract
An irrigation surgical tool system comprises a motorized handpiece, a tool for insertion in the handpiece, a console including a mounting plate and peristaltic pump rotor and a tube set including a cassette installable on the console for peristaltic pumping of irrigation liquid to the tool. Passages in the tool allow irrigation liquid flow, between a fixed outer tube and rotating inner tube of the tool, to a surgical site, through windows in the tool inner and outer tubes. Application of suction to the tool enables withdrawal through the inner tube of irrigation and surgical debris from the surgical site.
