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.

Surgical irrigation pump and tool system

Apparatus for guiding insertion of surgical instruments into a surgical site while blocking escape of fluids, including gas under pressure, therethrough from the surgical site. A generally Y-shaped housing comprises an elongate instrument guide having a distal end insertable in the surgical site and an elongate instrument passage through which elongate instruments are insertable into the surgical site. A valve seat is provided in the instrument passage. A valve member is movable into contact with the valve seat for blocking escape of fluid from the surgical site therepast along the instrument passage when no instrument occupies such instrument passage. Such housing includes a tubular valve guide having an elongate valve passage intersecting the instrument passage and along which the valve member is movable toward and away from the valve seat. The valve member is urged resiliently along the valve passage toward the valve seat for closing the instrument passage when no surgical instrument is in the instrument passage and for resiliently allowing a surgical instrument inserted into the instrument passage to push aside the valve member, back into the valve passage, to allow continued insertion of the surgical instrument past the valve member into the surgical site.
