The connecting structure is used for connecting the insertion hose and the elbow part, is annular, and comprises a rear connecting section connected with the insertion hose and a front connecting section connected with the elbow part; at least one hollow flexible pipe extends out from the insertion hose of the endoscope; the end part of the hollow flexible pipe is fixed on the connecting structure; at least one positioning structure is correspondingly arranged at the circumferential wall of the front connecting section for positioning the hollow flexible pipe. The hollow flexible pipe is positioned at the circumferential wall of the front connecting section by arranging the positioning structure, so the hollow flexible pipe is more accurately and firmly fixed on the connecting structure.
Description
Technical field
The present invention relates to endoscopic technique field is and in particular to a kind of endoscope inserts the connection knot of flexible pipe and bending section
Structure, and the endoscope using this attachment structure.
Background technology
Referring to Fig. 1, flexible endoscope is generally by can insert internal insertion section 1 and be connected with the cardinal extremity of insertion section 1
Operating portion 2 forms.Bending section 12 and bending that insertion section 1 is connected with this insertion flexible pipe front end by elongated insertion flexible pipe 11
Portion 12 front end is connected and is arranged at insertion section 1 cephalic par 13 foremost and forms.The cardinal extremity of insertion flexible pipe 11 is with operating portion 2 even
Connect.
Operating portion 2 passes through four steel wire ropes and controls bending section 12 four direction bending vertically and horizontally, guiding endoscope head
End 13 reaches suitable observation or operating position.Four steel wire ropes are placed in insertion flexible pipe 11 and the passage of bending section 12, steel
Four ends of cord one end are separately fixed in cephalic par 13, and the other end is connected to four chains in operating portion 1
On bar tail end.The part that four steel wire ropes are located in insertion flexible pipe 11 passage be respectively placed in four hollow flexible pipes 14 (referring to
Fig. 3), and behind the junction through insertion flexible pipe 11 and bending section 12, the steel wire rope guide pipe of setting in bending section 12,
Extend to cephalic par 13.Hollow flexible pipe 14 has preferable elasticity, by the guide effect to steel wire rope for the hollow flexible pipe 14,
Operating portion 2 has good smoothness to the control of steel wire rope.One end of four hollow flexible pipes 14 is fixed on operating portion 2,
The other end is fixed on the end of insertion flexible pipe 11 and the junction of bending section 12.
Described hollow flexible pipe 14, refers to tolerate high-temperature soldering, has good flexibility, the slender pipeline of elasticity,
The general spring serpentine pipe made using metal.
Fig. 2 is the schematic diagram that in prior art, endoscope inserts the attachment structure that flexible pipe is used with bending section junction, Fig. 3
It is that the insertion flexible pipe of the endoscope employing attachment structure shown in Fig. 2 in prior art is shown with the structure fractionation of bending section junction
It is intended to.For convenience of observing and describing, in Fig. 3, eliminate the structure outside attachment structure and hollow flexible pipe 14.Referring to Fig. 2,
Attachment structure 15 is circular, including with insert that flexible pipe 11 is connected be followed by section 152, and connect section before being connected with bending section 12
151.Referring to Fig. 2 and Fig. 3, flexible pipe 11 will be inserted by attachment structure 15 and be connected with bending section 12, four hollow flexible pipes 14
End connects the inwall of section 151 before being weldingly fixed on attachment structure, the welding position of four hollow flexible pipes 14 respectively with bending section
In 12, the position of steel wire rope guide pipe is corresponding.The inwall of flexible connecting structure 15 is smooth, cylindrical peripheral surface, and flexibility is by specific
Frock clamp connects the inwall of section 151 before being fixed to four hollow flexible pipes 14, be then subjected to.Due to hollow flexible
Pipe 14 does not position, it is possible to make hollow flexible pipe 14 position move during removing frock clamp, causes hollow soft
