摘要： A surgical retractor for use with a spinal stabilization system including a plurality of bone anchors and a plurality of anchor extensions. The surgical retractor includes a frame positionable between a first anchor extension connected to a first bone anchor implanted in a first vertebra and a second anchor extension connected to a second bone anchor implanted in a second vertebra and a first retractor blade connectable to the frame for retracting tissue between the first anchor extension and the second anchor extension.

摘要： A valve unit capable of being implanted in a patient and having adjustable performance settings, such as pressure settings and/or flow control, to regulate passage of a bodily fluid. A casing defines a port for the bodily fluid, and a valve mechanism positioned at the port includes a movable valve member. The valve unit further includes a rotor disposed at a first location in the casing and having an axle which turns about an axis of rotation. The rotor defines a plurality of arcuate, radially flat cam surfaces. Each cam surface occupies an arc about the axis of rotation. A spring arm unit is disposed at a second location in the casing having a cam follower arm in slidable contact with the cam surfaces of the rotor and having a resilient spring element applying a closing effect with the movable valve member to establish a performance setting for the valve unit. Sufficient rotation of the rotor to change the cam surface in contact with the cam follower alters the closing effect with which the valve member moves relative to the port and thereby alters the performance setting of the valve unit.
