Abstract
A kind of double-screw type bending tubular construction involved by the utility model on endoscope, it includes swan-neck gum cover, because the swan-neck gum cover is internally provided with the cannon born of Bidirectional screw type, the shielding glue net with shielding action is provided between cannon born and the swan-neck gum cover.In use, because the cannon born is bidirectional screw pipe composition, be advantageous to improve cannon born intensity, cannon born toughness and raising pipe stability.In addition, compared with bend in one direction pipe of the prior art, swan-neck of the present utility model has easy to operate effect.
Description
【Technical field】
It the utility model is related to endoscopic technique field, more particularly to a kind of endoscope in terms of medical endoscope
Double-screw type bending tubular construction.
【Background technology】
Endoscope is a kind of medicine equipment commonly used in the prior art, meanwhile, and domestic medical middle most of Medical treatment device
The more enervated Medical Instruments of tool.Described endoscope includes being used for the insertion section for being inserted directly into inside of human body, can arbitrarily bend
Bending section, and the control end for manual control operation handle part.The bending section includes directly with insertion section connecting
The swan-neck connect, it is arranged the soft pipe sleeve located at swan-neck periphery.Medical care operating personnel are in use, be typically all to be set by control
Put in control end, drive the bending section to move, bending section drives the whole insertion section motion.In operation, by
In the low intensity for the swan-neck being arranged inside bending section, toughness is low, and swan-neck stability is low, causes operating to operating personnel
When bring it is highly inconvenient.
【Utility model content】
In view of this, technical problem to be solved in the utility model, which is to provide one kind, can improve swan-neck intensity, toughness
And the double-screw type bending tubular construction on stability, easy to operate endoscope.
Solves above-mentioned technical problem for this, the technical scheme in the utility model is using the double-screw type on a kind of endoscope
Tubular construction is bent, it includes swan-neck gum cover, and the swan-neck gum cover, which is internally provided with, can improve intensity, improves toughness and carries
The cannon born of the Bidirectional screw type of senior executive's stability, the shielding with shielding action is provided between cannon born and the swan-neck gum cover
Glue net.
Further limited according to technical characteristics, the cannon born includes interior bonding jumper, outer bonding jumper；It is interior since head end
Bonding jumper is placed in inside outer bonding jumper, and two inside and outside metals form hollow two-way spiral shell to equidirectional or opposite direction spiral simultaneously
Coil.
Further limited according to technical characteristics, the swan-neck gum cover is that sleeve is made by plastic material.
Advantageous effects of the present utility model：Because the swan-neck gum cover is internally provided with the cannon born of Bidirectional screw type,
The shielding glue net with shielding action is provided between cannon born and the swan-neck gum cover.In use, because the cannon born is
Bidirectional screw pipe forms, and is advantageous to improve cannon born intensity, cannon born toughness and raising pipe stability.In addition, with the prior art
Bend in one direction pipe compare, swan-neck of the present utility model has easy to operate effect.
With reference to the accompanying drawings and examples, the technical solution of the utility model is described in further detail.
【Brief description of the drawings】
Fig. 1 is the structural representation of the double-screw type bending tubular construction on endoscope in the utility model；
Fig. 2 is the schematic perspective view of cannon born in the utility model.
【Embodiment】
In order that technical problem to be solved in the utility model, technical scheme and beneficial effect are clearer, clear, with
Under in conjunction with the accompanying drawings and embodiments, the utility model is further elaborated.It is it should be appreciated that described herein specific real
Example is applied only to explain the utility model, is not used to limit the utility model.
It refer to shown in Fig. 1 and Fig. 2, the double-screw type swan-neck knot on a kind of endoscope illustrated with reference to embodiment
Structure, it includes swan-neck gum cover 1, cannon born 3, shielding glue net 2.
The cannon born 3 includes interior bonding jumper 31, outer bonding jumper 32；Since head end, interior bonding jumper 31 is placed in outer bonding jumper
Inside 32, two inside and outside bonding jumpers 31,32 form hollow bidirectional screw pipe to equidirectional or opposite direction spiral simultaneously.It is described
Swan-neck gum cover 1 is that sleeve is made by plastic material.
The cannon born 3 is arranged on inside swan-neck gum cover 1, and the shielding glue net 2 is arranged on swan-neck gum cover 1 and pipe
Between bone 3.In the present embodiment, the cannon born 3 is made up of bidirectional screw pipe, and the cannon born 3 can improve intensity, is improved tough
Property and stability.
In summary, because the swan-neck gum cover 1 is internally provided with the cannon born 3 of Bidirectional screw type, the cannon born 3 and bending
The shielding glue net 2 with shielding action is provided between pipe gum cover 1.In use, because the cannon born 3 is bidirectional screw pipe group
Into,
Be advantageous to improve cannon born intensity, cannon born toughness and raising pipe stability.In addition, with it is of the prior art unidirectional curved
Curved tube compares, and swan-neck of the present utility model has easy to operate effect.
Above by reference to preferred embodiment of the present utility model has been illustrated, not thereby limit to right of the present utility model
Scope.Those skilled in the art do not depart from any modification made in the scope of the utility model and essence, equivalent substitution and changed
Enter, all should be within interest field of the present utility model.
