End is each passed through the middle through hole positioned at the side of center vertical panel two of fixed seat, and is fixed with location-plate, therefore, is forcing in
During different bracing wires, you can interlock fixed seat and swung to correspondence side direction, and reach and control distal end of catheter can sideshake bending
Purpose, obtain significant progressive.
Concrete technical scheme is：
A kind of airway wall guiding-tube bend structure,
It includes a main elastomeric spring circle, two mini elastic turns and a fixed seat, wherein：
Main elastomeric spring circle is the inside of flexible pipe for being located at airway wall distal end of catheter, and its external diameter is slightly smaller than the internal diameter of conduit；
Two mini elastic turns are then located at two side positions relative inside main elastomeric spring circle, and there is provided the two of airway wall
Bracing wire is extended through therebetween；And
Fixed seat is incorporated into the distalmost end of conduit, and it is provided with multiple through holes, and the distal end of foregoing two bracing wire is each passed through
Two through holes, and to be fixed respectively in connection with location-plate.
It is preferred that, the fixed seat is provided with a central vertical plate, and each through hole is located at its both sides, makes the distal end of two bracing wires
It is each passed through the middle through hole of the side of fixed seat central vertical plate two.
It is preferred that, the fixed seat is provided with a central openings, a combined body, formation work duct, and each through hole
Fixed seat outer rim annulus is respectively arranged on, in being provided with orientation bar in the through hole of wherein relative two sides, and the distal end of two bracing wires point
Not Chuan Guo another two side of fixed seat two through holes.

【Embodiment】
Refer to Fig. 2, shown in 3, the present embodiment is a kind of airway wall guiding-tube bend structure, mainly by a main elastomeric spring
Circle (1), two mini elastic turns (2) and a fixed seat (3) are constituted, wherein main elastomeric spring circle (1) is to be located at tracheae
The flexible pipe of mirror conduit (4) distal end is internal, and its external diameter is slightly smaller than the internal diameter of conduit (4), and two mini elastic turns (2) are then set
Extended through therebetween there is provided the two of airway wall bracing wire (5) in the internal two relative side positions of main elastomeric spring circle (1), it is foregoing
Fixed seat (3) is located at the distalmost end of conduit (4), and it is provided with a central vertical plate (31), and its both sides is respectively provided with multiple through holes
(32), the distal end of two bracing wires (5) is each passed through the middle through hole of the side of center vertical panel (31) two of fixed seat (3), and respectively
It is fixed with location-plate (33), and completes the bendable structure of the present invention.And other through holes in fixed seat (3) can then be provided
Power line and connecting line are worn therebetween, to connect the photographing module, illuminator and near-end controlling organization and power sector of distal end.
In use, because main elastomeric spring circle (1) and mini elastic turn (2) itself have flexible, therefore,
When forcing in different bracing wire (5), the location-plate (33) of bracing wire (5) distal end can interlock fixed seat (3) and be put to respective side direction
It is dynamic, the separation that the fixed seat (3) passes through central vertical plate (31), it can be ensured that it can only be to the both sides direction of central vertical plate (31)
Bending is tilted, and reaches the hose sections of control distal end of catheter, can stablize the state swung towards both sides direction, as shown in figure 4, being to obtain
The purpose of conduit (4) distal end bending is caused, significant progressive person is obtained.
It is the alternate embodiment of the present invention referring again to Fig. 5, fixed seat (6) therein has a central openings (61), and
Set in its annular exterior with several through holes (62), the central openings (61) are available for one body of connection and are formed as service pipe,
The distal end of two bracing wires (5) is also arranged in two through holes of fixed seat (6) opposite side respectively, and two through holes in another two side are built-in
If with orientation bar (63), being that can control fixed seat (6) under the gearing of different bracing wires (2), being able to accurately curved towards correspondence direction
Song, and distal end of catheter hose sections flexural oscillations are driven, the present invention is increased its application, improve practical effect person.
In summary, the warp architecture that the present invention is improved, its fabrication schedule is simple, repeatedly mutually to be detained without such as known
Close or riveted is pivotally connected multiple units, and energy simple combination reaches simple control airway wall conduit in the inside hose of body distal end
The purpose of distal end flexural oscillations, more conventional design obviously has more splendid practical improvement person.
