Dash uses smart instrument technology to turn normal surgical tools into intelligent measurement instruments which are accurate and reproducible. This self-contained device is stored in a handy travel case but expands into a system which surgeons can use to assist them with procedures involving hip joint and knee replacement procedures. A sterilely draped iPod Touch is set in a specialized cradle which acts as the system's monitor for use directly at the surgical site. This portable system is easy to set up and has a one-case learning curve. It contains a full orthopedic software portfolio which seamlessly integrates into various workflows, accurately contributing to precise implant positioning.
