Description
[ technical field ] A method for producing a semiconductor device
The utility model belongs to the technical field of the endoscope technique and specifically relates to indicate kinds of crooked pipes of locating the endoscope and inserting the end.
[ background of the invention ]
The endoscope is medical instruments commonly used in the prior art, wherein the endoscope comprises an insertion end for directly inserting into a human body, a bending tube which is connected with the insertion end and can be bent freely, and a handle end for manual control operation.
[ Utility model ] content
In view of the above, the technical problem to be solved by the present invention is to provide kinds of endoscope bending tubes with smooth and flat inner wall and outer surface.
Therefore, the technical problem is solved, the endoscope bending tubes adopted by the technical scheme of the utility model comprise armor tubes, wherein inner film layers are arranged on the inner walls of the armor tubes, and outer film layers are at least arranged on the outer portions of the armor tubes.
According to a main feature defined in step , the inner and outer membrane layers are each flexible tubes made of a plastic material.
The utility model has the advantages of the beneficial technical effect of the intraductal surface of armor is equipped with interior rete, and armor outside of tubes surface is equipped with outer retes at least, and the sheetmetal of the armor pipe inner wall that is formed by the sheetmetal book is covered by interior rete with the clearance between the sheetmetal, makes the armor inside pipe wall smooth, is equipped with several outer retes in armor outside of tubes portion moreover for replace traditional metal mesh cover, thereby make the crooked outer wall of tubes level and smooth, the armor inside pipe wall is smooth to be convenient for pass and pulls steel wire and various pipelines, compares with prior art, the utility model discloses simple structure, the processing of being convenient for provides very big facility moreover for subsequent assembly.
The technical solution of the present invention will be described in detail in steps with reference to the accompanying drawings and embodiments.
[ description of the drawings ]
FIG. 1 is a perspective view of a middle endoscope of the present invention;
FIG. 2 is a perspective view of a armor tube according to the present invention;
fig. 3 is a schematic cross-sectional view of a bending tube of a middle endoscope according to the present invention.
[ detailed description ] embodiments
In order to make the technical problems, technical solutions and advantages of the present invention to be solved clearer and more obvious, the present invention is described in detail below with reference to the accompanying drawings and embodiments in steps.
Referring to fig. 1 to 3, kinds of endoscope bending tubes mainly used in kinds of endoscopes including a handle end 1, an endoscope bending tube 2 connected to the handle end 1 to be optionally bent, and an insertion end 3 connected to the other end of the endoscope bending tube 2 to be directly inserted into the human body are described below in connection with an embodiment, the handle end 1 includes a handle housing, a gear train provided outside the handle housing to control a traction wire, and a plurality of parts provided inside the handle housing, the insertion end 3 includes a camera module, a snake bone assembly provided at a lower end of the camera module, the snake bone assembly includes a plurality of endoscope snake bones, a snake bone mesh installed on an outer periphery of the endoscope snake bones, a snake bone rubber installed on an outer periphery of the snake bone mesh, and at least four traction wire ropes installed inside the plurality of endoscope snake bones, the four traction wire ropes pass through the plurality of endoscope snake bones to an inner film 21 provided on an inner surface of the endoscope bending tube 20, and at least provided on an outer surface of the armor tube 20.
The inner film layer and the outer film layer are respectively flexible tubes made of plastic materials.
In order to smooth and even the outer surface of the curved tube, generally requires a base outer film layer.
To sum up, armor pipe 20 inside surface is equipped with interior rete 21, armor pipe outside surface is equipped with outer rete 22 at least, and the clearance between the sheetmetal of the armor intraductal wall that is formed by the sheetmetal winding and the sheetmetal is covered by interior rete, makes the armor intraductal wall smooth, is equipped with several outer retes in armor outside of tubes moreover for replace traditional metal mesh cover, thereby make crooked pipe outer wall level and smooth, the armor intraductal wall is smooth to be convenient for pass and pulls steel wire and various pipelines, compare with prior art, the utility model discloses simple structure, the processing of being convenient for provides very big facility moreover for subsequent assembly.
The preferred embodiments of the present invention have been described above with reference to the accompanying drawings, without thereby limiting the scope of the invention. Any modification, equivalent replacement and improvement made by those skilled in the art without departing from the scope and spirit of the present invention should be within the scope of the claims of the present invention.
Claims (2)
