Abstract
A percutaneous tracheostomy assembly has a hollow needle carrying a cannula with a hub at its rear end abutting a hub on the needle. A channel-shape stop is clipped onto the cannula and needle so that its rear end abuts the hub of the cannula. The stop has a laterally-extending flange at its forward end. The length of the stop is such that the tip of the needle and the forward end of the cannula are positioned within the trachea when the flange abuts the skin of the neck, without the risk of the needle contacting the posterior wall of the trachea.
