ABSTRACT:
A needle sheath complex and related process for external use of the complex for decompressing or sampling tissue within a multitude of areas in human and animal bodies.
The needle sheath complex is comprised of a small gauge needle which is comprised of a stylus within a cannula and which is long enough so that a shorter outer sheath can be slidable located on the small gauge needle leaving exposed a long enough portion of the smaller gauge needle to probe the body and locate the area to be decompressed or sampled. The small gauge needle is inserted into the body and when the target area has been located, the outer sheath is slid over the small gauge needle into the body stretching the opening to the target. The smaller needle is then removed leaving the larger inside diameter sheath in place in the body through which sampling or decompression can be performed. The invention includes means and processes for easily removing and reinserting the stylus within the cannula and means and processes for readily attaching or detaching the stylus from the cannula.
The invention includes means for locking the cannula of the small gauge needle to the stylus thereby freeing both hands for guiding the small gauge needle to the target.
A key feature is the removable means for locking the probe cannula to the stylus which enables changing the outer sheath without removal of the probe cannula or stylus from the target area.
