Patent number: 10034754Abstract: A surface protection system comprising a protective sleeve positionable over an orthopedic tool or implant, for example the tapered end of an orthopedioc femoral stem implant to shield the covered surface from exposure to abrasive particles during an automated polishing process is described. The protective sleeve comprises a body having an annular sidewall that extends from a proximal end to a distal end and is composed of a polymeric material. A cavity resides within the body extending through the distal end to a proximal end sidewall positioned perpendicular to the annular sidewall. The protective sleeve further comprises at least one annular recess intermediate at least two annular ridges that reside along an interior surface at the distal end of the sleeve. These series of annular ridges and recesses form a removably tight seal around the exterior surface that minimizes the migration of abrasive polishing particles to the exterior surface of the orthopedic tool or implant.Type: GrantFiled: September 14, 2015Date of Patent: July 31, 2018Assignee: Greatbatch Medical S.A.Inventor: Luc Vautrin

Patent number: 8784458Abstract: An improved insert for assembly with a bone plate is described. The insert has a first opening adapted to receive a set screw and a second opening adapted to receive a bone screw. The insert is connectable to the bone plate using a set screw. The insert in conjunction with the set screw provides an improved range of relative motion for placing the bone screw at outboard locations with respect to the bone plate. That way, bone fragments that are not necessarily reachable using the bone plate without the insert can be secured together for improved healing.Type: GrantFiled: October 13, 2009Date of Patent: July 22, 2014Assignee: Greatbatch Medical S.A.Inventors: Patrick M.

Patent number: 8657834Abstract: A surgical tool handle for releasable connection to a surgical tool is described. The tool handle comprises a housing providing a linkage chamber extending from a proximal housing grip end to a distal housing tool end for receiving a surgical tool. A tool linkage is partially housed within the housing linkage chamber comprising an axial handle region extending along axis A-A and a radiused housing region curving about a focal point. That way, a locking pawl of the tool linkage changes planes from its proximal end to a distal extending hook end. This provides a relatively short connection to a surgical tool that is optimum in the tight space requirements of a minimally invasive hip surgery.Type: GrantFiled: March 4, 2011Date of Patent: February 25, 2014Assignee: Greatbatch Medical S.A.Inventor: Jonas Burgi

Patent number: 8657833Abstract: A surgical tool handle for releasable connection to a surgical tool is described. The tool handle comprises a housing providing a linkage chamber extending from a proximal housing grip end to a distal housing tool end for receiving a tool. A tool linkage is partially housed within the linkage chamber. That way, manipulation of the tool linkage causes a locking pawl to pivot with respect to the housing from an open configuration ready to receive a tool for attachment to the housing to a closed configuration engageable with the tool supported at the distal housing tool end.Type: GrantFiled: March 3, 2011Date of Patent: February 25, 2014Assignee: Greatbatch Medical S.A.Inventors: Jonas Burgi, Jeremy Degrave

Patent number: 8491586Abstract: Disclosed is a surgical tool holder adapted to connect to a disposable cutting tool, and the surgical instrument combination. The tool holder has a shank with a quick tool coupling at one end and a drive adaptor at a second end. The coupling assembly has a coupling interface for holding the tool, and has a debris reservoir. A locking mechanism is engageable with the shank by a lock interface that holds the coupling assembly in functional assembly, and when unlocked allows component parts of the coupling assembly to be separated for cleaning and sterilization. The surgical tool has a flat base and complementary fittings adapted to be received by the holder's coupling interface. The combination of the flat base with the reservoir defines a relatively enclosed collection space to receive cutting debris from the tool while the holder and tool are coupled together.Type: GrantFiled: February 6, 2008Date of Patent: July 23, 2013Assignee: Greatbatch Medical S.A.Inventors: André Lechot, Yann Rossé, Didier Guélat

Patent number: 8475466Abstract: A torque-limiting driver for orthopedic surgical use is described. The torque-limiting driver has a housing to which a torque force may be applied and transferred to a driver output shaft. The housing encloses a cam bearing assembly having a ball cage disposed so that balls of the ball cage move along a first vector path (Vr) radial to the axis of rotation. The bearing assembly also has an inner race abutting the ball. The inner race travels along a second vector path (F) parallel to the axis of rotation. The first vector path (Vr) and the second vector path (F) are not co-axial. A bearing load assembly applies a bias force (F) to the inner race of the cam bearing assembly to set the calibrated maximum amount of torque that can be transmitted via the housing through the cam bearing assembly to the output shaft of the torque-limiting driver.Type: GrantFiled: December 18, 2007Date of Patent: July 2, 2013Assignee: Greatbatch Medical S.A.Inventor: Fabrice Chenaux
