APPARATUS AND METHODS FOR INTER-OPERATIVE VERIFICATION OF APPROPRIATE SPINAL PROSTHESIS SIZE AND PLACEMENT
摘要
<p>A distractor and measuring device includes a first handle operatively connected to a first paddle and a second handle operatively connected to a second paddle. The first and second handles are pivotally connected to one another such that movement of the handles relative to one another causes the paddles to move relative to each other. At least one transducer is positioned on at least one of the first and second handles for measuring an amount of force applied during distraction. A measurement rod is pivotally connected to the device and is movable in a longitudinal direction relative to the first and second paddles. A potentiometer is operatively connected to the measurement rod to measure the angular orientation of the measurement rod.</p>
