    摘要: A first instrument having a distal end is sized and configured to penetrate tissue and a proximal end comprising a first handle assembly. A second instrument including an interior lumen is sized and configured to accept passage of the first instrument. The second instrument has a proximal end comprising a second handle assembly sized and configured to releasably interlock with the first handle assembly to form a composite instrument sized and configured to provide percutaneous access to a cancellous bone region. The second handle assembly is also sized and configured to permit controllably release by a user of the first handle assembly from the second handle assembly to allow removal of the first instrument from the interior lumen. At least one additional instrument is sized and configured for passage through the interior lumen of the second instrument upon removal of the first instrument.
