The front end of described bending section is fixed by described outer groove, inner groove grafting.
Preferably, described outer layer includes steel disc layer and top layer, and described steel disc layer wraps up described steel mesh layer, and described top layer is wrapped
Wrap up in described steel disc layer.
Preferably, described steel disc layer is set to the steel disc layer that steel disc is bent to form through spiral, and described steel disc layer is sheathed on institute
State steel mesh layer and wrap up described steel mesh layer.
Preferably, described top layer is set to PU layer or layer of silica gel.
Preferably, said structure also includes connecting portion, the steel mesh layer other end of described outer tube bend inwards parcel described curved
The follower head inner surface of pars convoluta, described connecting portion plug is located at the follower head of described bending section, is made described steel mesh layer bend inwards
Outer surface is in close contact with described connecting portion outer surface.
Compared to prior art, this utility model is by the front end of the parcel bending section that bent inwards by the end face of steel mesh layer
The fixing connection of front end being located at bending section is also filled in end by inner surface, makes the end face of steel mesh layer be crushed on bending section front end
Between inner surface and the outer surface of end, prevent the burr of steel mesh layer end face from causing the out-of-flatness of outer tube end face that patient is caused
The serious consequences such as scratch.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain this
Utility model, is not used to limit this utility model.
As shown in Figure 1 and Figure 2, this utility model provides the fixed structure of a kind of endoscope outer tube, including end 11, bending
Portion 12 and the outer tube 16 of parcel bending section 12；Wherein, outer tube 16 includes steel mesh layer 161, steel disc layer 162 and top layer 163, steel disc
Layer 162 wraps up steel mesh layer 161, and steel disc layer 162 is wrapped up on top layer 163, and end 11 is provided with outer groove 111, the front end of bending section 12
Head is provided with inner groove 121.When bending section 12 is connected with end 11, one end of steel mesh layer 161 bends inwards parcel inner groove
The surface of 121, the inner groove 121 of bending section 12 is located at by outer groove 111 plug of end 11 makes end 11 fixing with bending section 12 even
Connect；Now, steel mesh layer 161 inner surface bent inwards and the intimate surface contact of inner groove 121, the steel mesh layer bent inwards
161 outer surfaces and the intimate surface contact of outer groove 111, steel disc layer 162 is put down with the end face of bending section 12 with the end face on top layer 163
Together.
In the present embodiment, steel mesh layer 161 is set to the steel mesh layer of grid type, utilizes the hardness of steel mesh layer 161 to support
Outer plastic cement top layer 163, prevents plastic cement top layer 163 from caving inward, and steel mesh layer 161 is set to grid type steel disc layer simultaneously, utilizes
The flexibility of network facilitates it to bend.Steel disc layer 162 is set to the steel disc layer that steel disc is bent to form, specially spring through spiral
Shape, steel disc layer 162 is sheathed on steel mesh layer 161 and wraps up steel mesh layer 161, utilizes the elasticity of spring-like steel disc layer to make outer tube 16 in bending
Rear quickly reinstatement.Plastic cement top layer 163 is set to PU material layers, wraps up steel disc layer 162, make use of resistance to complications of PU material, soft
Softness is good, tensile strength is big, smooth surface etc. makes outer tube be readily bent and resistance to complications, pliability are good, tensile strength.
