Orthopedic navigation system with sensorized devices

摘要

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.

主权项

1. A surgical orthopedic alignment system comprising:
a receiver, where the receiver includes a first transducer that is configured to receive or emit an ultrasonic signal, and where the receiver is configured to contact a portion of a muscular skeletal system; a wand, where the wand includes a second transducer that is configured to emit or receive the ultrasonic signal, where the wand is configured to be moveable to a point on at least one of the muscular skeletal system or a device; and a processor, where the processor is configured to use the time of flight of the ultrasonic signal between the wand and the receiver to determine positional location of the wand with respect to the receiver, where the positional location of the wand with respect to the receiver is used to determine alignment of the portion of the muscular skeletal system with respect to the point, where the determination of alignment occurs within a sterile field of an operating room, where the receiver further includes a controller operatively communicatively coupled to the first transducer, and where the receiver further includes an accelerometer.
