Description
Technical field
The present invention relates to endoscope, particularly, relate to a kind of endoscope insertion part and disposable endoscope.
Background technology
Endoscope is a kind of conventional medical apparatus and instruments, and form by being arranged on the insertion section of operating portion front end, bending section and leading section, wherein insertion section, bending section and leading section are collectively referred to as insertion tube.Through the natural hole of human body, or the minimal incision * that underwent operative is done enters in human body; During use, the insertion tube of endoscope is imported the organ of preliminary examination, directly can spy on the change of relevant portion.
Domestic medical endoscope market major part is occupied by external product, price from several ten thousand to hundreds of thousands not etc., each with after to carry out complexity and the sterilization of high cost, maintenance, likely cause cross infection because disinfecting steps is lack of standardization.Be provided with aquaporin of supplying gas/send, attraction channel and biopsy channel in traditional insert tube of endoscope and control cable, signal cable and optical fibers.Elongated passage thorough disinfection is very difficult, but due to the cost of manufacture of current endoscope expensive, must reuse.Be necessary to improve conventional endoscope, to reduce the risk of expense and cross infection.
Current all known endoscope main flexible pipes, its basic structure is all overlap the netted pipe of being worked out by stainless steel silk outward at the bourdon tube by flat stainless steel band coiling, on netted pipe, then cover the coating layer be made up of elastomeric material.These bourdon tubes, netted pipe and coating layer, with regard to manufacture, require high, complex process.As: bourdon tube, requires four angle impulse-free robustness of flat stainless steel band, and coiling pitch is even, and internal-and external diameter concordance will wait well.The manufacture of netted pipe, needs the metalworking technologies such as high-precision braider, end-o f-pipe-control, is difficult to automated manufacturing.After bourdon tube puts netted pipe, also need one trimming, to ensure that the tensile elongation of main flexible tube is no more than regulation requirement.Otherwise, when using endoscope, built-in thing can be caused impaired because the tensile elongation of main flexible tube exceedes regulation requirement.Netted pipe covers coating layer, then needs repeatedly to apply elastomeric material, to ensure the circumferential uniform wall thickness of coating layer, and the peel strength of coating layer meets regulation requirement.Therefore the manufacture requirements of main flexible tube is high, and operation is various, complex process, causes large-scale production difficulty large, and cost intensive.And disposable endoscope is to the requirement of main flexible tube, be then under the prerequisite that can meet instructions for use, energy large-scale production, cost is extremely low.Therefore, current all known endoscope main flexible pipes, cannot meet the requirement of disposable endoscope, result in medical field for many years has strong demand to disposable endoscope always, and does not have real disposable endoscope product to satisfy the demands at all.
For a long time, the traditional view of this area is thought: endoscope main flexible pipe must be made up of bourdon tube, netted pipe and coating layer, the normal use of guarantee endoscope main flexible pipe.There is certain technology prejudice in this kind of viewpoint in fact, only have be only when endoscope needs life-time service correct: bourdon tube, being to ensure that main flexible tube has certain compressive property, avoiding endoscope impaired due to improper operation in the Reusability process loading instrument container, taking-up, operation use, sterilization, storage, transport etc.; Netted pipe is to ensure that the tensile elongation of main flexible tube is no more than regulation requirement on the one hand, is on the other hand to avoid coating layer to embed bourdon tube.And disposable endoscope is disposable, the access times of the loading instrument container, taking-up, operation use, storage, transport etc. of endoscope are less, and do not need sterilization, and the probability of improper operation just reduces greatly, therefore, and completely can without bourdon tube.Without bourdon tube, then netted pipe is not just needed to embed bourdon tube to avoid coating layer yet, as long as ensure that the tensile elongation of main flexible tube is no more than regulation and requires.Therefore, can adopt one-time formed main flexible tube completely, not only be convenient to large-scale production, cost is also significantly reduced, and can meet the normal instructions for use of endoscope.
In prior art, endoscope insertion part structure is comparatively complicated, thus assembly cost and manufacturing cost higher, through there being the retrieval of technology to line, find that application number is 200680001267.6, name is called a kind of endoscope easy to manufacture of the disclosure of the invention of endoscope insertion part, endoscope insertion part wherein has inner tubular member, outer tubular member and operating line, above-mentioned inner tubular member has roughly barrel shape, and at least extend on whole bending section, be enclosed within outside above-mentioned outer tubular member in inner tubular member, there is roughly barrel shape, at least extend on whole bending section, aforesaid operations line is used for carrying out bending operation to above-mentioned inner tubular member and above-mentioned outer tubular member, at least one party's tubular element in inner tubular member and outer tubular member has linking part and at least 2 cylindrical portion, these linking parts and at least 2 cylindrical portion form as one, above-mentioned linking part has elasticity, by adjacent cylindrical portion flexibly interlink, between inner tubular member and outer tubular member, the line maintaining part that can keep operating line with retreating is formed by above-mentioned inner tubular member and above-mentioned outer tubular member.Endoscope insertion part structure in this invention is comparatively complicated, thus assembly cost and manufacturing cost higher.
