Technical problem of the present invention is solved by following further technical scheme.
Described compliant section is provided with the trapezoidal cylinder of perforation by some centers and drag wire forms, and drag wire shuttles back and forth in trapezoidal cylinder and bores a hole, and by integral for some trapezoidal cylinder connections, one end of drag wire is connected with the controls on handle.
Described controls is a slip ring that can move axially along handle, and slip ring is connected with drag wire.
Described each trapezoidal cylinder varies in size, and trapezoidal angle is different.
Described each trapezoidal its center is provided with two parallel perforation.
Described handle end is also provided with an auxiliary traction ring, and auxiliary traction ring is connected with drag wire.
The described guide rod length being connected with compliant section is slightly longer than tracheal intubation.
The present invention's beneficial effect is compared with prior art:
This guide device of endotracheal tube structure is simple, processing ease, be arranged on the compliant section of guide rod arc tips under the traction of drag wire, the compliant section can handling guide rod far-end bends according to designing requirement direction, form unique serpentine to bend, the patient throat anatomical structure of combining the symptoms such as the dead angle of formation before making the curved end of guide rod and structure variation or pachymucosa or glottic edema or vocal cords adapts, the smooth insertion of guidance tracheal intubation.Adopt this guide device of endotracheal tube to implement endotracheal intubation, not only can comparatively fast complete tracheal intubation operation, the tissue injury caused because of improper operation in endotracheal intubation can be reduced simultaneously.
The concrete structure of guide device of endotracheal tube of the present invention is provided in detail by the following drawings and embodiment.

Detailed description of the invention
Embodiment: can be clear that guide device of endotracheal tube is by being provided with the hollow guide rod 1 of arc tips 2, the compliant section 3 being connected to arc tips 2 and the handle 4 that is connected to hollow guide rod 1 tail end forms from Fig. 1.
Described compliant section 3 as shown in Figure 2, be made up of 5 column diameter sizes trapezoidal cylinder 32 of the first trapezoidal cylinder 31, second, the 3rd trapezoidal cylinder 33, the 4th trapezoidal cylinder 34, the 5th trapezoidal cylinder 35 and drag wire 7 from big to small, the diameter of first trapezoidal cylinder 31 one end adapts with hollow guide rod 1 port diameter and is connected, second trapezoidal cylinder 32 larger diameter end is connected with the smaller diameter end of the first trapezoidal cylinder 31,3rd trapezoidal cylinder 33 larger diameter end is connected with the smaller diameter end of the second trapezoidal cylinder 32, by that analogy.Each trapezoidal cylinder 31,32,33,34,35 center is all arranged with two perforation 6.Drag wire 7 shuttles back and forth in each trapezoidal cylindrical perforation 6, and by integral for tactic 5 trapezoidal cylinder series connections, one end of drag wire 7 enters from hollow guide rod 1 end perforating machine, draws, be connected with the controls 8 be arranged on handle 4 from the tail end of hollow guide rod 1.
Described controls 8 is the slip rings 9 that axially can move around along handle 4, and described slip ring 9 kink is on handle 4, and the drag wire 7 of drawing from the tail end of hollow guide rod 1 is connected with slip ring 9.
Slip ring 9 on mobile handle 4, can be drawn compliant section 3 bending of hollow guide rod 1 end by the tractive of slip ring 9 pairs of drag wires 7, its flexibility is determined by the size of pull strength: pull strength is large, and the flexibility of compliant section 3 is large; Pull strength is little, and the flexibility of compliant section 3 is little.The shape that compliant section 3 is bending is then determined by each trapezoidal cylindrical gradient and arranged in series: if trapezoidal cylindrical minor axis side orientation is contrary with the bending direction of guide rod arc tips, then under the traction of drag wire 7, the compliant section after flexural deformation 3 and hollow guide rod 1 arc tips can be made to form " S " shape, this tool " S " shape imports the intubate guide of end because of leading portion changeable shape, can change with anatomical structure and adjust entry angle, can with combine the throat's anatomical structure forming the patient with sympotoms such as dead angle before variation or pachymucosa or glottic edema or vocal cords and adapt, bootable tracheal intubation is inserted put in place (see Fig. 6) smoothly.If trapezoidal cylindrical minor axis side orientation is consistent with the bending direction of guide rod arc tips, under the traction of drag wire, the compliant section after flexural deformation 3 and hollow guide rod 1 arc tips can be made to form the larger insertion end of flexibility.
For convenience of operation, handle 4 end is also provided with an auxiliary traction ring 10, and auxiliary traction ring 10 is also connected with drag wire 7, compliant section 3 bending that draw hollow guide rod 1 end same with the auxiliary traction ring 10 that drag wire 7 connects,
The described length being connected with the hollow guide rod 1 of compliant section 3 is slightly larger than tracheal intubation length.
Above content is in conjunction with concrete preferred implementation further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, its framework form can be flexible and changeable, can subseries product.Just make some simple deduction or replace, all should be considered as belonging to the scope of patent protection that the present invention is determined by submitted to claims.
