Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to the crooked controlling organization of a kind of medical endoscope.
Background technology
Endoscope is a kind of conventional medical apparatus and instruments, insertion section, bending section, leading section, control part and main frame, consists of, and wherein insertion section, bending section and leading section are collectively referred to as insertion tube.Through the natural duct of human body, or the little otch that underwent operative is done enters in human body; Use the organ of the insertion tube importing preliminary examination of Shi Jiang endoscope, can directly spy on the variation at relevant position.
Endoscope is a kind of enervated medical apparatus and instruments, domestic medical endoscope market major part is occupied by external product, price is not from several ten thousand to hundreds of thousands etc., each with after to carry out complicated and expensive sterilization, maintenance, likely because disinfecting steps is lack of standardization, cause cross infection.In traditional insert tube of endoscope, be provided with the aquaporin of supplying gas/send, attraction channel and biopsy channel and control cable, signal cable and optical fibers.Elongated passage thorough disinfection is very difficult, but because the cost of manufacture of current endoscope is expensive, must reuse.Be necessary conventional endoscope to improve the risk of reduction expense and cross infection.
Independently dismountable disposable products had been engendered afterwards, Chinese invention patent " 201110056640.0 " discloses " a kind of purification type medical endoscope ", its structure is: include the soft total body case of endoscope, in the soft total body case of endoscope, be provided with endoscope main body, endoscope main body by medical resin material by imaging lens assembly, LED light source and optical fiber light-guiding bundle, power line together with holding wire shroud ring, in endoscope main body, be provided with various passages.
There is following problem in above-mentioned technology: whole medical resin or the flexible material of adopting made, its poor rigidity, in use, and the affected part of can not going directly, and angle of bend is little, narrow application range.The soft total body case of endoscope main body and endoscope still needs sterilization, and unrealized disposable use truly.
Chinese invention patent " 200880017615.8 " discloses " a kind of curved part of endoscope ", this curved part of endoscope comprises having cylindrical portion (28), a plurality of joint ring (26A that are set up in parallel coaxially mutually, 26B), two adjacent joint ring (26A, 26B) one joint ring (26A) has with cylindrical portion (28) and is wholely set, the protuberance (32) radially extending along cylindrical portion (28), two adjacent joint ring (26A, another joint ring (26B) 26B) has with cylindrical portion (28) and is wholely set, the receiving portion (42) that can insert rotationally centered by the length axes of protuberance (32) for protuberance (32), each joint ring (26A, 26B) there is extend across with the circumferencial direction of cylindrical portion (28) disengaged in cylindrical portion (28) or engage complete discontinuous portion (34).
