Multi-fit suction irrigation hand piece



Multi-fit suction irrigation hand piece



Official Gazette of the United States Patent & Trademark Office Patents 1249(4), Aug 28



A disposable hand piece providing irrigation and aspiration capability to a surgical field can adaptably hold within itself endoscopes of different manufacturers. Running through the hand piece is a bore; attached at the distal end of the hand piece is a reusable sheath. The tubular shaft of an endoscope is inserted into the bore of the hand piece and the reusable sheath. A first collet at the proximal side of the hand piece securely holds the endoscope by adjusting to the outer diameter of the tubular shaft of the endoscope. A second collet at the distal side of the hand piece holds the reusable sheath in a selected linear extension. The collets, however, permit the tubular shaft and the reusable sheath to be rotated in place and thus adjust the view of the surgical field. An annular space is maintained between the tubular shaft and the reusable sheath so as to provide a channel for irrigation and aspiration. Further aspiration capability is provided by a separate suction device. A method of attaching an endoscope and sheath to the hand piece and using the apparatus is also disclosed.
