Surgical irrigation pump and tool system
First Claim
1. A surgical irrigation peristaltic pump system for supplying and irrigating surgical instrument from an irrigation liquid source said pump system compressing:
- a console including a mounting plate and a peristaltic pump rotor rotatably supported on said mounting plate, said rotor carrying hose compression rollers;
a tube set including a cassette having a body in turn having longitudinal and lateral and wideness dimensions, said body including ends spaced longitudinally thereon and sides spaced laterally thereon and a concave backing wall extending rearwardly thicknesswise of said body and concavely opening toward one end of said body, a peristaltic pump hose having a pumping portion backed by said concave backing wall and inflow and outflow portions extending from said cassette and flanking said pumping portion, means for connecting said hose inflow and outflow portions respectively to an irrigation liquid source and an irrigated surgical tool, said cassette being releasably fixable on said mounting plate in a peristaltic pump operative position in which said hose compression rollers compress said hose pumping portion against said concave backing wall, said console and cassette respectively including relatively engagable means for fixing said cassette on said console, said cassette being a single integral piece.

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.
