Background technique
With the fast development of medical technology, endoscope is also more and more extensive in the application of medical field.Endoscope is one
Kind common medical instrument, insertion section, bending section and front end by operation portion front end is arranged in form, wherein insertion section, curved
Pars convoluta and front end are collectively referred to as insertion tube.The small notch that natural hole or underwent operative through human body are done enters in human body；Make
The insertion tube of endoscope is imported the organ of preliminary examination by the used time, can directly pry through the variation in relation to position.
Existing medical endoscope is to reuse, and it is expensive, and the price of an endoscope is up to 300,000 yuan of people
People's coin or so.Due to needing to reuse, to avoid the cross-infection between patient, every endoscope after use all must be through
Cross stringent and complicated disinfectant program.According to the related disinfection technology working specification that the Ministry of Public Health promulgates, an endoscope is being used
The cleaning and disinfection treatment by 6~10 steps are needed afterwards, it is at least 20 minutes time-consuming.For the pain for mitigating patient, patient is allowed
More preferable to restore faster, medical instrument constantly develops towards small but excellent direction, for medical endoscope field, for being inserted into people
More stringent requirements are proposed for the medical devices section of body, as the thinner insertion tube the better, image request is more clear, function is all the more neat
Congruence.But the indispensable component of some in endoscope, that does is more tiny, it is also caused to be easier to damage.Such as CMOS figure
As sensor, it is easy to be damaged by external force vibration；Bending section for another example, operator's improper use are possible to be broken off, and
These components are once damaged, and whole endoscope cannot use, and maintenance cost is high.Imported product price is very high, international top-brand
As Olympus, STORZ endoscope price all more than hundreds of thousands, critical component is also easy to be damaged, in addition repeat make
Cleaning, disinfection after etc. can all damage endoscope.
Disposable products have been gradually appeared later, and Chinese invention patent application " 201110056640.0 " discloses " a kind of
Purification type medical endoscope ", structure are: including the soft overall encasement of endoscope, setting in the soft overall encasement of endoscope
