As proved by the clinical experiment result, the device has a simple structure, can be applied to imaging and calculus removing of an endoscopic pancreaticobiliary duct, is convenient to operate, and can be used for eliminating difficulty in the operation technology, shortening the operation time, increasing the calculus removing success ratio, and relieving the pain and the economic burden of a patient.
Description
Technical field
The invention belongs to technical field of medical instruments, relate to a kind of device of the ERCP of being used for choledocholithiasis lithotomy, be specifically related to a kind of netted stone taking device.
Background technology
Choledocholithiasis is clinical common disease; Sickness rate is very high, can cause clinical symptoms such as stomachache, heating, jaundice, nausea and vomiting, like concurrent biliary tract infection or calculus generation incarceration; Can cause septicemia, biliary tract perforation, hemorrhage and even shock, be critical acute abdomen.Because the fast development of endoscopic technic, choledocholithiasis Therapeutic Method change lithotomy under the first-selected scope into by the traditional surgery treatment.(ERCP) art of ERCP under the scope and lithotomy wound are little, and the complication that can avoid surgical operation to cause has become the main flow that present therapeutic modality is selected.
Choledocholithiasis according to the volume size be divided into than maximum size (>=2cm) and than microlith (＜2cm), can be divided into single-shot calculus and multiple calculus according to calculus quantity, the patient often follows choledochectasia, the choledochectasia degree different patients differ greatly.Stone taking device has basket under the clinical scope commonly used at present, and air bag etc., basket are got stone and adopted the multi-ring snare method that is similar to, and single calculus is taken out; Air bag get stone be with air bag after crossing calculus, expanding reaches the common bile duct internal diameter size, drags then and takes calculus out of.After bigger calculus often adopted mechanical lithotripsy, gradation was taken out again.Clinical practice shows that after handling by above-mentioned instrument, most calculus can be easier to take out, yet for the obvious expansion person of biliary tract, wherein defies capture with basket than microlith, and air bag since diameter restrictions also be difficult to " dragging " and go out these microliths.
Summary of the invention
The objective of the invention is to overcome the defective and the deficiency of prior art, a kind of endoscopic stone extraction technique instrument easy to use is provided, be specifically related to a kind of netted stone taking device.This netted stone taking device can easily take out less calculus from the common bile duct of expansion, thereby improves the success rate of ERCP (ERCP) lithotomy under the scope.
Fishing net shape stone taking device under the scope provided by the invention makes and gets the stone class of operation and be similar to fishing net fishing, also can catch easily for microlith; Solved the technical barrier of present ERCP lithotomy; Can obviously shorten operating time, reduce operation risk, the patient also will therefrom benefit.
Particularly, netted stone taking device of the present invention is characterized in that, it mainly is made up of epitheca pipe (1), inner core tube (2), handle (3), traction seal wire (4) and lithotomy net (5); Described inner core tube (2) and lithotomy net (5) are positioned at epitheca pipe (1) inside, and the head end of inner core tube (2) links to each other with lithotomy net (5); Described traction seal wire (4) is arranged in the duct of inner core tube (2), and the little ring of an end and lithotomy net (5) front end is fixed, and the other end connects handle (3).
Among the present invention, the diameter of epitheca pipe (1) is 2.2 mm-3.2mm, can be through the biopsy duct of duodenoscope.
Among the present invention, inner core tube (2) central authorities establish the duct, and traction seal wire (4) is arranged in the duct.
Among the present invention, handle (3) connects an end of traction seal wire (4).
Among the present invention, lithotomy net (5) adopts elastic steel traveler and nylon wire to process, and is similar to fishing net; Lithotomy net (5) elastic steel traveler front end is provided with a little ring, is connected, fixes with traction seal wire (4).
Among the present invention, when off working state, lithotomy net (5) is shunk back in epitheca pipe (1) with inner core tube (2); When clinical use, described lithotomy net (5) stretches out epitheca pipe (1), launches automatically, is " fishing net " form; Tractive traction seal wire (4), reclaim on lithotomy net (5) top, " fishing net " opening retraction; Calculus is held, and stone taking device withdraws from then, takes out calculus.
Through clinic trial, the result shows that the present invention utilizes the fishing principle to be used for bile duct and gets the stone operation technique, and easy to use, operation is convenient, does not need extra training; This netted stone taking device, simple in structure, can be used for the ERCP operation technique, can solve the difficulty on the present operating technology details, shorten operating time, improve the lithotomy success rate, alleviate patient's misery, reduce patient economy burden.
For the ease of understanding, through accompanying drawing and specific embodiment netted stone taking device of the present invention is carried out detailed description below.What need particularly point out is, specific embodiment and accompanying drawing only are in order to explain that obviously those skilled in the art can explain according to this paper, and the present invention is carried out various corrections or change, and these corrections and changing also will be included within the scope of the invention.
