Abstract
The utility model relates to a fast tracheal dilator in the medical instrument field. The fast tracheal dilator has the technical proposal that the fast tracheal dilator comprises an outer thimble and a wire cable passing through the outer thimble, as well as an extending steel mesh and a pull rod which are connected at the two ends of the wire cable, wherein, the outer thimble is composed of a continuously twisted inner-layer steel belt and an outer-layer rubber layer, a handgrip glove is fixed at the rear end of the outer thimble, the pull rod slides in the handgrip glove in a telescopic way, the extending steel mesh is composed of more than three steel wires which are connected in a head to tail arrangement way to form a football-shaped shape, the front end of which is connected with the wire cable, a lantern ring passing through the wire rope is preformed at the rear end, and the lantern ring is lapped with the front end of the outer thimble. As adopting the tough outer thimble, the fast tracheal dilator is facilitated to insert and move in the trachea, thereby being not easy to damage the tracheal wall, and the straining and extending steel mesh is adjustable, thereby having regulatory role of extending the caliber, satisfying the clinical application demands to the greatest extent, and also realizing the effects of clamping foreign bodies in the trachea or delivering drugs through extending and shrinking ways.
Description
Technical field
This utility model relates to a kind of quick trachea dilator in the medical instruments field.
Background technology
It is the respiratory system common sympton that tracheal stenosis and foreign body stop up, and understands the crisis life security when serious, does not also have a kind of apparatus of special use in the clinical practice at present.Chinese patent discloses a kind of trachea dilator (patent No. 200620085891.6), and comprise trocar sheath and connect the interior steel wire rope of trocar sheath, and the expansion steel wire and the pull bar that are connected the steel wire rope two ends.It is that to promote steel wire rope by pushing drawing rod descending, this moment the steel wire rope front end the expansion steel wire from trocar sheath, release, thereby realize the effect of expansion patient's trachea.Its defective is that trocar sheath is a hard tube, is difficult for being interspersed in the trachea, expands the expansion bore of steel wire in addition and fixes, and is difficult to satisfy practical application.
The utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and a kind of convenient, adjustable quick trachea dilator of expansion ratio simple in structure, interspersed are provided.
Its technical scheme is: comprise trocar sheath and connect the interior steel wire rope of trocar sheath, and the expansion steel wire and the pull bar that are connected the steel wire rope two ends, steel band and outer layer rubber layer that trocar sheath is twined continuously by the helical form of internal layer are formed, telescopic outside end is fixed with a glove, pull bar is telescopic slide in glove, described expansion steel wire connects the back from beginning to end by the steel wire more than 3 and forms American football shape, its head end is connected with steel wire rope, the terminal collar that connects steel wire rope that is shaped in advance, the front end overlap joint of the collar and trocar sheath.
Also be included in handle in the such scheme and put and be provided with the locking bolt, the locking bolt passes the pull bar lock fit in handle jacket wall and the cover, and is provided with draw ring in the outer end of pull bar.
This utility model overall structure is simple, owing to adopted the toughness trocar sheath, made things convenient for dilator endotracheal interspersed and mobile, be difficult for the injury tracheal wall, adjustable tension expansion steel mesh structure has expansion bore regulating action, can satisfy clinical practice to greatest extent, and, can also realize foreign body in the gripping trachea or send to the effect of medicine by the expansion and the form of shrinking.
Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of this utility model.
The specific embodiment:
With reference to accompanying drawing, trocar sheath adopts outer layer rubber layer 6 to coat internal layer continuous helical winding steel 7 structures, and the centre is penetrated with steel wire tow line 5 (similar existing gas backguy).Telescopic outside end (left end) is fixed with a glove 4, and being interspersed with pull bar 2 in the glove 4, the inner of pull bar 2 connects steel wire tow line 5, and the outer end is provided with draw ring 1, and pull bar 2 is by being fixed on locking bolt 3 (bolt) lock in place on the glove 4.The other end of steel wire tow line 5 stretches out from trocar sheath front end (left end), fixedlys connected with the head end 10 of expansion steel wire 9.Expansion steel wire 9 forms American football shape after adopting 5 steel wires to connect from beginning to end, and its head end 10 is connected with steel wire rope, the terminal collar 9 that connects steel wire rope that is shaped in advance, and the collar 9 overlaps with the front end of trocar sheath.
During use, at first pull bar is retracted in the glove, expands also radial contraction of steel wire this moment, after slowly being inserted into lesions position along trachea, again pull bar is pulled out a glove, expand steel wire head end radial dilatation under the effect of steel wire tow line this moment, thereby realize the effect of expansion trachea.If lesions position has foreign body, the expansion steel wire radial spacing after the expansion enlarges, and foreign body enters in the net, loosens pull bar again, and the own radial contraction of expansion steel wire is clamped in foreign body wherein, makes things convenient for foreign body.Inject solid shape medicine to lesions position if desired, at first medicine is placed in the expansion steel wire, then dilator is inserted lesions position, pull out pull bar this moment, expansion steel wire radial dilatation, medicine is deviate from netting, and falls into intralesional.
Claims (2)
1, a kind of quick trachea dilator, comprise trocar sheath and connect the interior steel wire rope of trocar sheath, and the expansion steel wire and the pull bar that are connected the steel wire rope two ends, it is characterized in that: steel band and outer layer rubber layer that trocar sheath is twined continuously by the helical form of internal layer are formed, telescopic outside end is fixed with a glove, pull bar is telescopic slide in glove, described expansion steel wire connects the back from beginning to end by the steel wire more than 3 and forms American football shape, its head end is connected with steel wire rope, the terminal collar that connects steel wire rope that is shaped in advance, the front end overlap joint of the collar and trocar sheath.
