Abstract: An adjustable collet mechanism for a surgical handpiece which enables the surgical tool driven by the handpiece to be oriented at selected angular positions relative to the handpiece axis. The coupling means includes a non-rotatable sleeve attached to the handpiece and a rotatable sleeve attached to the collet holding the surgical tool. The abutting faces of the non-rotatable and rotatable sleeves are angled relative to the handpiece axis so that relative rotation of the components causes their axes to be positionable either in alignment or at a predetermined angular orientation. The coupling mechanism includes a tubular coupling link which enables relative rotation between the rotatable and non-rotatable sleeves while also enabling translation of power from the handpiece to the surgical tool.

Abstract: A surgical cutting instrument having an elongated rotatable inner member provided with a cutting edge at its distal tip, the inner member adapted to rotate within an elongated outer tube having a window adjacent its distal end adapted to cooperate with the cutting edge of the inner member. The outer tube is provided with a portion thereof adjacent its distal end which enables the distal tip of the outer tube to be bent at an angle relative to the proximal portion of the outer tube. The outer tube may be bent by a user into a selected angular position with the aid of a tool calibrated in a plurality of discrete positions. The tool is adapted to enable the outer tube to be rotated to any selected position prior to being bent so that the window at the distal tip of the outer tube may be caused to face in any desired direction relative to the bend in the outer tube.

Abstract: A shrinkable foam mandrel that can be easily removed and composite resin transfer molding process that uses the foam mandrel. The foam is dimensionally stable at a first temperature that typically corresponds to the cure temperature of the composite resin. The foam is capable of irreversibly shrinking to less than about 0.5 said foam's original size at a second tempertaure that is above said first tempertaure. The foam is encapsulated by a non-stick elastomer skin and covered with fibers. The fiber covered elastomer encapsulated foam is disposed in a female mold cavity and resin is injected into the female mold cavity. The resin and fibers are cured and the resulting composite component is removed from the female mold. The temperature is raised to the second temperature and the elastomer encapsulated foam male mandrel irreversibly shrink to less than about 0.5 its original size. Finally the shrunken male mandrel is removed from said composite component. These mandrels are a solution to the aerospace industry's flyaway mandrel problem as they are lightweight and can easily be removed from the composite component.
