Appl. No.:

10/327526

Inventors:

Chelynne Nicole Lee - Warsaw IN, US
Donald Steven Block - Warsaw IN, US

Assignee:

Depuy Products, Inc. - Warsaw IN

International Classification:

A61F002/38

US Classification:

623 2015, 623 2028, 623 2031

Abstract:

A modular prosthetic knee implant system includes a femoral component, a femoral stem, a femoral stem collar, an augment and a bolt. The modular prosthetic knee system can be assembled in different ways. If assembled without the augment, the stem is at a valgus angle. If assembled with the augment, the stem is at a neutral angle. The stem collar has an inferior surface that is angled with respect to its superior surface, and the augment has a superior surface that is angled with respect to its inferior surface. The components also include mating anti-rotation members to fix the relative positions of the members.

Abstract:

Shallow angle furrows between crop beds are reshaped and cleaned in one pass using a tractor-towed implement having angularly even-spaced cutter blades mounted in tiers on drums for rotation about generally vertical axes, perpendicular to the furrow walls on opposing, angularly adjustable decks. The blades of the lower tier are angled to cut into the wall material laterally, parallel to the wall slope, without destroying the root structure of protective sod covering. The cut material is lifted up to the upper tier blades which are offset and lagged so as to eject the cut material up and beyond the furrow wall edges following cutting, in one continuous operation. Plates and pivotal deflectors mounted at the edges of the decks, direct the discharge of cut material. A bell crank and pivotal linkage provides for hydraulically assisted raising and lowering of the apparatus from and into ground contact.
