Background technology
Choledocholithiasis is clinical common disease, sickness rate is very high, can cause clinical symptoms such as stomachache, heating, jaundice, nausea and vomiting, as concurrent biliary tract infection or calculus generation incarceration, can cause septicemia, biliary tract perforation, hemorrhage and even shock, be critical acute abdomen.Owing to the fast development of endoscopic technic, the choledocholithiasis Therapeutic Method changes lithotomy under the first-selected scope into by the traditional surgery treatment at present.(ERCP) art of ERCP under the scope and lithotomy wound are little, and the complication of having avoided surgical operation to cause has become the bed therapeutic modality that current main-stream is faced.
Medically, 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, and the choledochectasia degree different patients differ greatly.
Stone taking device has basket, air bag etc. under the scope at present.Basket is got stone and is 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.In addition, bigger calculus is adopted the mechanical lithotripsy device, and then gradation is taken out.
In the clinical treatment, rely on the most calculus of above-mentioned instrument can be easier to take out, yet, wherein defy capture with basket than microlith for the obvious expansion person of biliary tract, and air bag since diameter restrictions also be difficult to " dragging " and go out these microliths.
Summary of the invention
The purpose of this utility model is defective and the deficiency that overcomes prior art, and a kind of endoscopic surgery instrument easy to use is provided, and is specifically related to a kind of netted stone taking device with handle with holes.This stone taking device is convenient to take out less calculus from the common bile duct of expansion, improves the success rate of ERCP lithotomy.
Netted stone taking device with handle with holes of the present utility model, make and get the stone class of operation and be similar to fishing net fishing, owing to adopted the lithotomy net that assumes diamond in shape when launching, also can catch easily for microlith, solved the technical barrier of ERCP lithotomy, shorten operating time, reduce operation risk, the patient also therefrom benefits.
Particularly, the netted stone taking device with handle with holes of the present utility model is characterized in that, it is made up of epitheca pipe (1), handle (2), traction seal wire (3) and lithotomy net (4); Described traction seal wire (3) and lithotomy net (4) are positioned at epitheca pipe (1) inside, and handle (2) links to each other with lithotomy net (4) by traction seal wire (3).
In the netted stone taking device of the present utility model, the diameter of described epitheca pipe (1) is 2.2 mm-3.2mm, can be by the biopsy duct of duodenoscope.
In the netted stone taking device of the present utility model, described handle (2) adopts four single hole operating handles.
In the netted stone taking device of the present utility model, described traction seal wire (3) adopts steel wire.
In the netted stone taking device of the present utility model, described lithotomy net (4) adopts the memorial alloy braiding to make, and has pliability; Lithotomy net (4) is established four end points, links to each other with four single hole operating handles of handle (2) by traction seal wire (3) respectively; Lithotomy net during off working state (4) is shunk back in epitheca pipe (1), and lithotomy net during expansion (4) assumes diamond in shape.
During the clinical use of this utility model, epitheca pipe (1) is inserted near the calculus, push handle (2), make lithotomy net (4) be deployed condition, pull back respectively each single hole operating handle of handle (2), make lithotomy net (4) hold calculus, stone taking device and scope together withdraw from then, take out calculus.
Through clinic trial, the result shows, this utility model will be fished thought and be used for bile duct and get the stone operation technique, stone taking device is simple in structure, easy to use, operation is convenient, does not need extra training, can solve the difficulty on present this operating technology details, and the shortening operating time, improve the lithotomy success rate, alleviate patient's misery, reduce patient economy burden, can be applicable to the ERCP operation technique.
For the ease of understanding, the netted stone taking device with handle with holes of the present utility model is described in detail below by the drawings and specific embodiments.It needs to be noted that specific embodiments and the drawings only are in order to illustrate, obviously those skilled in the art can illustrate according to this paper, and this utility model is carried out various corrections or change, and these corrections and changing also will be included within this utility model scope.
