US Patent:

8435244, May 7, 2013

Filed:

May 2, 2007

Appl. No.:

11/743485

Inventors:

Christopher M. S. Meek - Leesburg IN, US
Shaun R. Cronin - Fort Wayne IN, US
Peter E. Darrigan - Rockford OH, US

Assignee:

Zimmer, Inc. - Warsaw

International Classification:

A61B 17/56
A61B 17/88

US Classification:

606 86R, 606 99

Abstract:

An orthopedic tool for loosening the connection between orthopedic components. In one embodiment, the orthopedic tool includes a housing and a wedge. The housing has a head, an upper portion, a lower portion, and an opening between the upper and lower portions. The wedge is positioned at least partially between the upper portion and the lower portion of the housing and is actuatable to move toward the head of the housing. When at least a portion of the head of the housing is placed in mating engagement with the junction between two assembled orthopedic components, advancement of the wedge towards the head results in separation of the upper portion and lower portion of the housing. Thus, as the wedge is advanced toward the head, the upper and lower portions of the housing are separated, which results in corresponding separation of the assembled orthopedic components.

Assignee:

Zimmer, Inc. - Warsaw IN

International Classification:

A61B 17/92

US Classification:

606 99

Abstract:

A slap hammer tool and associated instrumentation to engage with the slap hammer tool are disclosed herein. In some examples, a slap hammer tool including an end adapted for engagement with a quick release connector of an instrument is provided. The instrument can be adapted to receive the distal end of the slap hammer for engagement, the engagement being provided through rotation of the slap hammer relative to the instrument. Once the slap hammer and instrument are engageably coupled, the slap hammer can be used to provide force and accompanying motion away from the instrument in the direction of the slap hammer instrument. Force can be provided by the slap hammer tool to a coupled instrument, for example, to move or extract the coupled instrument from placement on a surgical area.
