摘要:
A tracheostomy instrument (1) used for inserting a tracheostomy tube has a needle (10) with colored bands (13) along its length and connected with a syringe (14) at its machine end. The syringe (14) is used to detect when the trachea (3) has been penetrated; the depth of penetration is indicated by observing which colored band (13) aligns with the skin surface (5). The machine end of the tracheostomy tube shaft (20) has a number of colored bands (26) corresponding to the bands (13) on the needle (10). A flange (24) is movable along the tube (2) and is locked in position against the colored band (26) corresponding to the band (13) on the needle (10) aligned with the skin surface (5).

An apparatus (100) includes: a expandable structure (140) formable into three dimensional shapes including a range of diameters (D) and corresponding lengths (L); a movable component (106) moveable between a range of positions (124, 126) effecting the range of diameters; and a mechanical linkage (110) disposed between the movable component and the expandable structure. The expandable structure is configured to fit inside a working channel (204) of an endoscope (202) when the expandable structure is collapsed. The mechanical linkage is configured to move the collapsed expandable structure through the working channel to a selected location (400) past a distal end (404) of the endoscope and to increase and decrease a diameter of the expandable structure in response to changes in the position of the movable component when the expandable structure is at the selected location.
摘要:
A device for facilitating tracheotomy includes a first branch (14), which is adapted to be introduced down the trachea of a patient, such that the end thereof is located below the larynx, and a second branch (12), adapted to be arranged on the outside of the neck with the end thereof located adjacent to the site intended for the tracheostoma. The end of the second branch has a guiding tube for a needle, and the end of the first branch has a protection plate. When the needle is moved towards the skin through the guiding tube and penetrates the skin and tracheal wall in order to provide the tracheostoma, the needle is directed towards the protection plate, and may engage it after passage through the tracheal wall. In such a manner the other side of the tracheal wall is protected. Furthermore, the tracheostoma will automatically be located at the best position. The first branch (14) includes hooks (30, 31), adapted to slidingly engage with a tube (40) in trachea, the hooks being located close to the distal end of the first branch (14), for directing said first branch along said tube.

An introducer (100) for surgical airway catheters and the like, the introducer comprising: a handle (102) a first curved section (104) having a flattened cross section and connected to the handle; a first straight section (106) having an unflattened cross section and connected to the first curved section; a second curved section (110) having a flattened cross section and connected to the first straight section; a last straight section (112) connected to the second curved section and forming a distal end of the introducer.
摘要:
Systems, methods and devices for facilitating insertion of an endotracheal tube and/or verifying the position of the endotracheal tube within an airway of a patient with respect to an anatomical landmark of a patient are disclosed. Systems, methods, and devices for facilitating removal of debris from the distal airways of patient under direct visualization are also disclosed.
摘要:
An introducer for a surgical airway catheter has a proximal handle; a curved, rod-shaped main section; a cutting region; and a rod-shaped distal tip, all (except the handle) sized to receive the catheter tube. After making an initial opening in a patient's trachea, the operator inserts the distal tip of the introducer into the initial opening up to the cutting region. The operator uses the cutting region to sufficiently widen the opening by moving the introducer from side to side to enable the widened opening to receive the tube and cuff of the catheter. The operator rotates the introducer and catheter into the trachea through the widened opening and then removes the introducer leaving the catheter in place. The introducer and catheter can be pre-configured in a surgical kit that includes a retractable scalpel that can be configured onto the introducer's handle and used to excise the initial tracheal opening.
摘要:
A tracheostomy dilator is curved along its length having a tapering patient end region (5) at one end and an oppositely curved handle region (7) at its opposite end. A passage (10) extends rearwardly along the dilator from its patient end (4) and opens on a side of the dilator at an opening (12) in the handle region (7). The passage (10) is blocked rearwardly of the opening (12) by an insert (2) with a forward ramp surface (23), which directs a guidewire (30). In use, one end of the guidewire (30) projects from the patient end (4) of the dilator and its opposite end extends along the outside of the handle region (7).
