Description
Technical field
The present invention relates to endoscopic technique field, and in particular, to a kind of flexible pipe and combinations thereof.
Background technology
Endoscope is widely used in the fields such as industry and medical treatment, it generally has elongated flexible insertion tube.
When endoscope is observed in insertion cavity, different cavitys is multifarious, so as to insert tube of endoscope
It is it is required that also multifarious.Such as：Some cavitys are narrow and small and curved more, it is desirable to which insertion tube flexibility will be got well, and could smoothly reach observation mesh
Ground；Some cavity spaces are very big, it is desirable to which insertion tube will rigidly be got well, and could smoothly approach viewing area.
It is therefore desirable to which insertion tube front end is soft, it was easy to several curved, rear end rigidly then needs to be stepped up, to take into account
The bending property and insertion performance of insertion tube.
Known insert tube of endoscope all at present, its basic structure be all formed by flat stainless steel band coiling it is spiral
Pipe is outer to put on the netted pipe worked out by stainless steel wire, and the coating layer being made of elastic material is then covered on netted pipe.
In the insert tube of endoscope that industrial circle uses, can also be covered outside coating layer worked out by stainless steel wire or tungsten filament it is netted
Pipe, to increase wearability.
The insertion tube of the structure, will realize that the rigidity from front end to rear end is stepped up, difficult.It is both domestic and external at present
The state of the art is：Have plenty of by the change of coating layer material hardness to realize, but usage time is slightly long, and the change of hardness does not just have
；Have plenty of by a point some hardness difference helix tubes, weld together, then put on netted pipe, cover coating layer, but it is spiral
Pipe weld is easy to break；Have plenty of and helix tube is compressed to increase by the hardness of compression section insertion tube by haulage cable, but
Usage time is slightly long, and the length of insertion tube can shorten.
Moreover, needing to reverse the occasion observed of endoscope at some, the insertion tube moment of torsion transitivity of the structure compares
Difference, therefore after operating side torsion certain angle, the torsion of insertion tube front end cannot reach corresponding angle, so as to increase operation
Difficulty.
In addition, clamping deferent in endoscope, it is built in insert tube of endoscope, for being inserted into the apparatuses such as biopsy forceps, therefore,
The bending section of endoscope, pincers deferent also require softness；And requiring the endoporus of pincers deferent pipe to be the bigger the better, outside diameter is the smaller the better, and
Flexibility and crushing resistance are good, and the prior art is difficult to meet at the same time.
