摘要:
An osteotome instrument for use in computer assisted surgery is disclosed. The instrument includes a shaft, a connector, a handle, and a cutter component. The handle has a proximal end portion and a distal end portion. The cutter component is connected to the handle at the distal end portion. The connector is releasably connected to the handle at the proximal end portion, and the connector is adapted to rotate about the shaft relative to the handle. A fiducial for tracking is connected to the connector.

Surgical positioners may include platforms, surgical item positioners and/or surgical references as well as methods for using stabilizer platforms, surgical item positioners and/or surgical references. Stabilizer platforms may include low profile platforms rigidly mounted to portions of an individual's anatomy. Various items may be secured and/or stabilized by the stabilizer platform, including support platforms as well as surgical references. Support platforms may stabilize and assist surgeons in using, navigating, aligning and positioning surgical items. Surgical references may include modular fiducial systems that may be secured to stabilizer platforms, support platforms, surgical items and/or directly to portions of an individual's anatomy.
摘要:
A femoral neck anteversion guide for use with a femur having a prepared intramedullary canal. The guide includes a radiolucent stem having a distal end for inserting into the prepared intramedullary canal; and a radiopaque angle locator wire embedded within the stem at a known angle for allowing the femoral neck angle and femoral neck anteversion to be determined.

Embodiments of improved systems and processes for cutting bones. Embodiments of improved systems and processes for resecting a femoral bone are provided, the system comprising a guiding device adapted to be connected to the femoral bone, a cutting device having a cutting element adapted to resect bone, and a link adapted to connect to the guiding device to the cutting device, wherein the link is adapted to constrain movement of the cutting device. Embodiments of improved systems and processes for cutting knee bones during computer assisted knee surgery are provided, comprising at least one fiducial associated with the guiding device and a tracking functionality capable of tracking a position and orientation of the at least one fiducial.
摘要:
A modular portal for use with a computer-aided surgical navigation system. The modular portal is configured to receive a wide number of surgical items in either rotating or non-rotating fashions. A surgical reference associated with a base of the modular portal may be repositioned with respect to the base to facilitate a clear line of sight between a sensor of the computer-aided surgical navigation system and the surgical reference.

摘要:
Systems, methods and processes for computer-assisted soft tissue balancing, including ligament balancing, determining surgical cuts, and positioning or placement of the components of the prosthetic knee during TKR. The improved methods, systems and processes resolve several problems related to the prosthetic knee component positioning and soft-tissue balancing during computer-assisted TKR. The improved methods, systems and processes are flexible and versatile, provide reliable recommendations to the surgeon, and improve restoration of the knee function and patient recovery.
摘要:
A series of humeral stems, each stem including an axial bore and longitudinal slots along the distal end to allow for distal compression. The compression force necessary to compress the distal diameter of each stem varies by stem diameter. Thus, as the stem diameter increases through the series, the compression force decreases.
