TRACHEOSTOMY PUNCH DILATOR.

摘要

There is provided a device for performing an initial piercing and dilating of a patient's trachea. The device has a needle within and extending beyond a sheath. After the needle is used to pierce the trachea, it may be removed and a guide wire (J-wire) inserted. A introducer dilator surrounds the sheath and is slidable over the sheath. The introducer dilator has a first position away from the distal end of the sheath and a second position in which the distal end of the sheath is substantially covered by the introducer dilator. The introducer dilator is then used to expand the initial piercing.
