Abstract
Instrumentation for implanting an artificial intervertebral disc includes an inserter/impactor for inserting and removing the static trials and for inserting the artificial intervertebral discs, the inserter/impactor having at least one shaft having a longitudinal axis and a shaft distal end adapted for engagement with the trials and the disc, the shaft distal end further having forward surfaces for engagement with corresponding confronting surfaces of at least one of the baseplates for axial rotationally aligning the at least one of the baseplates with respect to the longitudinal axis.
Claims18
An apparatus for manipulating an orthopedic device having first and second baseplates, the apparatus comprising:
- at least one shaft having a longitudinal axis and a shaft distal end adapted for engagement with the device,
- the shaft distal end further having forward surfaces for engagement with corresponding confronting surfaces of at least one of the baseplates for axial rotationally aligning the at least one of the baseplates with respect to the longitudinal axis.
An apparatus for holding an orthopedic device, the apparatus comprising:
- a shaft having a distal end;
- an extendible and retractable holding pin located internal to at least a portion of the shaft distal end;
- and
- a spring coupled to the holding pin and located internal to at least a portion of the shaft and biasing the pin toward retraction;
- wherein a holding pin distal end of the holding pin is bent downwardly such that the holding pin distal end prevents the holding pin from being entirely retracted within the shaft under the bias;
- wherein the holding pin engages and disengages a corresponding holding pin device hole of the device;
- wherein the spring spring-loads the holding pin toward at least one shaft distal end surface of the shaft distal end such that when the holding pin is engaged with the corresponding holding pin device hole, the spring spring-loads at least one surface of the device to at least one of the shaft distal end surfaces.
