Description
Technical field
The present invention relates to endoscope, particularly, relate to a kind of curved part of endoscope 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 curved part of endoscope, all saved by multiple snake bone be connected with each other and form, its connecting device allows them relative to pivotable.Described connecting device is arranged on the face of these snake bone joint.These snake bone joint and connecting device, with regard to the manufacture of snake bone joint, and complicated; With regard to being linked and packed of snake bone joint, also complicated especially.Therefore, not only domestic external enwergy produces the manufacturer of curved part of endoscope seldom, and large-scale production difficulty is large, and cost intensive.And the requirement of disposable endoscope, be then want energy large-scale production, cost is extremely low.Therefore, current all known curved part of endoscope, cannot meet the requirement of disposable endoscope at all, and 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.
For a long time, the traditional view of this area is thought: curved part of endoscope must be saved by multiple snake bone and connecting device forms, the normal bent angle of guarantee curved part of endoscope.There is certain technology prejudice in this kind of viewpoint in fact, only have be only when endoscope needs life-time service correct.And disposable endoscope is disposable, the bent angle number of times of an operation endoscope bending section generally can not more than 50 times, as long as guarantee normal bent angle requirement.Therefore, can adopt one-time formed bending section completely, not only be convenient to large-scale production, cost is also significantly reduced, and can meet normal bent angle requirement.
In prior art, bending section generally adopts metal material to make, and not only cost is higher, and structure is comparatively complicated.Through the retrieval to prior art, find that application number is 200780040247.4, name is called a kind of structure for curvature section of endoscope of the disclosure of the invention of structure for curvature section of endoscope, the 1st stage portion of the angle limits for limiting swinging angle is respectively equipped with in the both sides of 2 tabs of the front side of joint ring leading section, the 2nd stage portion of the angle limits for limiting swinging angle is respectively equipped with in the both sides of 2 tabs of the rear side of joint ring rearward end, when bending section bends, when turning to maximum rotated position between 2 joint rings of the front and back of swan-neck, the restriction that the abutting saving the 1st stage portion of ring by the 2nd stage portion and rear side that are saved ring by front side carries out, being restricted to by mutual for the joint ring of front and back formed pendulum angle Α prevents trocar sheath from biting into the limited angular of the regulation between each joint ring when bending operation bending section, thus prevent overcoat from biting between each joint ring when bending operation bending section.But this invention structure is comparatively complicated, and forming difficulty, cost is higher.
