Abstract
Described herein are devices and related methods configured to establish that a femoral or humerus component implant is fully seated during femoral or humerus implant impaction. Such devices described herein may include a laser, detector, and processor and, optionally, a camera. Results of the device use may be transmitted to and/or displayed on a computing device.
Claims20
A device for monitoring a press fit of an orthopedic implement into a bone, the device comprising:
- a housing configured to at least partially contain a light source and a detector, wherein:
- the housing defines a window through which a light beam from the light source emanates and through which reflected light is received to interact with the detector,
- when the orthopedic implement is press fitted into the bone, the window is configured to face the bone;
- the housing is configured to be secured to a trunnion of the orthopedic implement;
- and
- a processor communicatively coupled to the light source and the detector;
- and a memory coupled to the processor, wherein the memory is configured to store program instructions that, when executed by the processor, cause the processor to perform a method comprising:
- outputting an activation signal to the light source to activate triangulation by emitting a light beam,
- receiving a first signal indicative of first reflected light sensed by the detector,
- determining a first distance to the bone based on the first signal,
- receiving a second signal indicative of second reflected light sensed by the detector,
- determining a second distance to the bone based on the second signal, and
- outputting an indication of the orthopedic implement being fully seated in the bone when a difference between the second distance and the first distance is less than a predefined threshold.

A device for monitoring a press fit of an orthopedic implement into a bone, the device comprising:
- a housing configured to at least partially contain a light source and a detector, wherein a light beam from the light source is configured to interact with the bone and the detector is configured to receive reflected light from the interaction,
- a clamp extending from the housing and configured to be secured to a trunnion of the orthopedic implement, wherein the clamp is configured to adjust a position of the housing in an x-y plane;
- an adjustment region between the housing and the clamp, the adjustment region configured to adjust the position of the housing along a z-axis that is perpendicular to the x-axis;
- a processor communicatively coupled to a laser and the detector;
- and a memory coupled to the processor, wherein the memory is configured to store program instructions that, when executed by the processor, cause the processor to perform a method comprising:
- outputting an activation signal to the laser to activate triangulation by emitting a laser beam,
- receiving a first signal indicative of first reflected light sensed by the detector,
- determining a first distance to the bone based on the first signal,
- receiving a second signal indicative of second reflected light sensed by the detector,
- determining a second distance to the bone based on the second signal, and
- outputting an indication of the orthopedic implement being fully seated in the bone when a difference between the second distance and the first distance is less than a predefined threshold.
