ABSTRACT:
The specification discloses a tracheostomy tube which is specifically designed for percutaneous insertion into a patient's trachea through a stoma in the neck between adjacent cartilages. The tracheostomy tube is inserted with an inner obturator as an assembly in conjunction with the Seldinger technique utilizing a guide wire, a guiding catheter, and dilators. The tracheostomy tube includes a soft, flexible tubular cannula which has a distal portion for insertion within the trachea and a proximal end remaining outside the trachea. The assembly includes a tubular obturator adapted to fit over the guiding catheter and adapted to closely fit within the cannula, and has a tapered distal end which extend beyond the distal end of the cannula. The distal end of the cannula is gradually tapered to form a smooth transition between the cannula and the obturator. The distal portion of the cannula has the end thereof beveled to one side so that the most distal tip of the cannula is narrow, angled and tapered and is introduced by the obturator generally midway between the adjacent cartilages. Once the narrow tip of the cannula is clearly inserted between the adjacent cartilages, the remaining angled and tapered distal end of the cannula is readily eased between the cartilages free of interference to facilitate insertion of the assembly. The outer cannula preferably includes a low profile inflatable cuff. The percutaneous tracheostomy tube and preparation and insertion devices are provided in a convenient kit.
