Technical field
The present invention relates to a kind of endoscope, more particularly to a kind of low cost disposable electric endoscope.
Background technology
Endoscope is a kind of conventional medicine equipment, by the insertion section, bending section and the leading section that are arranged on operating portion front end
Composition, wherein insertion section, bending section and leading section are collectively referred to as insertion tube.Through the natural hole of human body, or underwent operative is done
Small otch enters in human body；The insertion tube of endoscope is imported the organ of preliminary examination when using, relevant position can be directly spied on
Change.
Existing medical endoscope is reusable, and its 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 strictly and the disinfectant program of complexity.According to the related disinfection technology working specification that the Ministry of Public Health promulgates, an endoscope is being used
Need afterwards by 6~10 steps cleaning and disinfect, take at least 20 minutes.
Disposable products have been engendered later, and Chinese invention patent " 201110056640.0 " discloses " one kind purification
Formula medical endoscope ", its structure is：The soft overall encasement of endoscope is included, is provided with the soft overall encasement of endoscope interior
Sight glass main body, endoscope main body by medical resin material by imaging lens component, LED light source and optical fiber light-guiding beam, power line and
Holding wire shroud ring together, is provided with various passages in endoscope main body.
There is problems with above-mentioned technology：Overall to be made of medical resin or flexible material, its poor rigidity is being used
When, can not go directly affected part, and angle of bend is small, narrow application range.Endoscope main body and the soft overall encasement of endoscope are still
Need sterilization, and unrealized single use truly.
Chinese invention patent " 200880017615.8 " discloses " a kind of curved part of endoscope ", the curved part of endoscope bag
Include with cylindrical portion, coaxial with each other the multiple section rings being set up in parallel, a section rings in two adjacent section rings have with
The protuberance for radially extending that cylindrical portion is wholely set, along cylindrical portion, another section ring in two adjacent section rings has
Receiving portion being wholely set with cylindrical portion, can rotationally being inserted centered on the length axes of protuberance for protuberance, respectively
Section ring has extend across with the circumferencial direction of cylindrical portion in cylindrical portion disengaged or engages the discontinuous portion for finishing.
A kind of curved part of endoscope disclosed in foregoing invention patent, complex structure, manufacture difficulty is high, and production cost is high, no
Meet the making requirement of disposable endoscope.
The content of the invention
