First Claim
Patent Images
1. A surgical orthopedic alignment system comprising:
- a receiver coupling to a bone of the muscular-skeletal system; and
a wand ultrasonically coupled to the receiver to determine alignment of the muscular-skeletal system where the wand and receiver assess and report alignment and where points of interest are registered and tracked in three-dimensional space.

Abstract
A low-cost and compact electronic device toolset is provided for orthopedic assisted navigation. The toolset comprises wireless sensorized devices that communicate directly with one another. A computer workstation is an optional component for further visualization. The sensorized devices are constructed with low-cost transducers and are self-powered. The toolset is disposable and incurs less hospital maintenance and overhead. As one example, the toolset reports anatomical alignment during a surgical workflow procedure. Other embodiments are disclosed.

12. A disposable tool suitable for use in orthopedic alignment, the tool comprising:
-
a receiver coupled to a cutting jig; and a wand ultrasonically coupled to the receiver to register points of interest on a first and a second bone and transmit location data related to the points of interest to the receiver to assess a position of the cutting jig in relation to the orthopedic alignment of the first bone and second bone using the points of interest. - View Dependent Claims (13, 14, 15, 16)

17. A method of intra-operative alignment of a femur and tibia comprising the steps of:
-
affixing a receiver to a the distal end of the femur; registering a center of the distal end of the femur with a wand that is ultrasonically coupled with the receiver; placing the wand having a stationary line of sight position to the receiver; rotating the femur; and identifying points in 3D space corresponding to the femur rotation with time of flight and delta time of flight ultrasonic measurements between the wand and the receiver. - View Dependent Claims (18, 19, 20)
