Description
Technical field
The present invention relates to the field of medical instrument technology, and in particular to a kind of scalable enteroscope.
Background technology
Adult's small intestine total length is about 5-7 meters, accounts for the 70%~80% of intestines and stomach overall length.The incidence of disease of intestine accounts for
The 0.3%~1% of disease of digestive tract, but due to its special anatomical structure, the diagnosis and treatment of disease of intestine are always difficulty medically
Topic.Although capsule endoscope can realize the inspection that small intestine is non-invasive, visual, capsule endoscope limits to there is the visual field, can not control
System, the shortcomings of can not being accurately positioned and catching image randomness, it is maximum the shortcomings that be that capsule endoscope can not carry out biopsy, work as hair
Enteroscope, which is still needed to, after existing problem takes biopsy to judge lesion nature, and current enteroscope one shares three kinds, monosaccate, double bolloon
And helix tube enteroscope, but the operation of these three enteroscopes is very cumbersome and time-consuming tediously long, is generally 60 minutes into the mirror time
More than, and be difficult to endure and need row anesthesia check under patient awoke's state, this causes the increase of patient's inspection risks, and part
For patient because self reason cannot go anesthesia, directly results in this some patients can not row small intestinal endoscopy.And because small intestine
Mirror is complicated, even if having grasped the scope doctor of common Gastrointestinal Endoscopes operating technology, still needs to take a significant amount of time carry out enteroscope
Training could skillfully grasp operating method, and need double cooperation to complete the inspection of enteroscope.Therefore it is clinically anxious
Need a kind of easy to operate, quick enteroscopy system.The inspection of common colonoscopy at present is generally 5-10 minutes, and skill into the mirror time
It is tolerable under patient awoke's state when the skilled scope doctor of art operates.The length of common colonoscopy is generally 1.3 meters, but some
Patient still fails to complete endoscopy after the completion of causing into mirror since large intestine is longer or colon camber is larger, in this case
Generally require to use instead 1.8 meters of overlength colonoscopy, but because shank is long, the hook daraf(reciprocal of farad) production of the right hand cannot be effectively conducted in use
Raw strength, patient often feel more common colonoscopy into pain during mirror, and replace again in inspection colonoscopy also tend to
Patient has aggravated psychological burden, meanwhile, two scopes of cleaning also increase the decontamination cost of Endoscope room.So, if common
Colonoscopy effectively shorten and again pull out the second segment of scalable enteroscope after large intestine length, can not only smoothly complete highly difficult big
Intestines inspection is without changing mirror, and the inspection of feasible part small intestine halfway.As new enteroscope, this scope will greatly shorten mesh
Preceding enteroscope carries out down into the mirror time, and without anesthesia, while reduces the cultivation cycle of scope doctor, can do big colonoscopy i.e.
Can grasp the operating technology of enteroscope, but can one man operation, without double cooperation.And this scope is but also as conventional big colonoscopy
Use, greatly reduce the vacancy rate of common enteroscope.
