Everting device and method for tracheostomy

a tracheostomy and everting technology, applied in the direction of tracheal tubes, respirators, catheters, etc., can solve the problems of causing errors, slow healing, and surgery-related complications, so as to reduce the trauma of the intervening and adjacent tissue, minimize the potential for microbial infection, and simplify the tracheostomy

Benefits of technology

[0008]The present invention utilizes everting technology, in combination with novel means for placement and maintenance of airway tubes, to simplify tracheostomy, reduce trauma to the intervening a...

Problems solved by technology

The procedure involves multiple steps to create and dilate a stoma and insert a tracheostomy tube, each additional step creating the possibility for error.
Standard dilators, such as the BLUE RHINO manufactured by Cook Critical Care, and serial dilators, are inserted with a substantial, axially-inward force to dilate the patient's tissue, which, in addition to requiring significant physical strength on the part of the surgeon, may result in surgery-related complications such as bleeding; perforation of the adjacent vasculature, esophagus, and thyroid; pneumothorax and pneumomediastinum; subcutaneous and mediastinal emphysema; cartilage fractures; and suprastomal collapse.
Further, dilatators drag against the patient's tissue with a shear force and considerable friction, ca...

Embodiment Construction

[0037]The everting placement device of the invention, shown with various modifications in the figures includes a pushing means, which may comprise a pusher 110 or be integrated with another component, a guide 130, which is positioned and held at the appropriate location on the neck of the patient, and a first everting film sheath 120.

[0038]The pusher 110 has a proximal end 111 and a tapered distal nose 115 through which a longitudinal lumen 125 or other storage space opens. The pusher 110 is preferably flexible and pre-formed to be curved so as to allow the pusher 110 to curve caudally into the trachea 101.

[0039]The guide 130 includes connector means, which may be a tube-like connector 139 structure as shown, with a distal end 131 and proximal end 132, and also preferably includes an extension 135 or stand-off guide 460 for supporting the pusher 110. The guide also preferably includes a flange 137 that may be positioned at the appropriate location on the patient's neck and that is s...

Abstract

An integrated device and improved method for tracheostomy which includes the placement of an everted film sheath into a patent's trachea, through which the tracheal tube is inserted.

Description

BACKGROUND OF THE INVENTION[0001]The invention relates to an improved method and related devices for percutaneous placement of airway tubes into the tracheas of living bodies, a procedure known as a tracheostomy, and subsequent supportive maintenance tracheostomy.[0002]Trachesotomies are the most common surgical procedure performed on critically ill patients. The procedure involves multiple steps to create and dilate a stoma and insert a tracheostomy tube, each additional step creating the possibility for error. Standard dilators, such as the BLUE RHINO manufactured by Cook Critical Care, and serial dilators, are inserted with a substantial, axially-inward force to dilate the patient's tissue, which, in addition to requiring significant physical strength on the part of the surgeon, may result in surgery-related complications such as bleeding; perforation of the adjacent vasculature, esophagus, and thyroid; pneumothorax and pneumomediastinum; subcutaneous and mediastinal emphysema; c...
