In general, with choledochus, ductuli hepaticus communis, left and right calculus of hepatic duct patient, usually will appear abdominal pain, obstructive yellow subcutaneous ulcer and
The clinical symptoms such as fever.For the patient for being reluctant to operate or have operation taboo, recurrence after operation, postcholecystectomy etc., adopt
It is first choice with treatment ERCP (taking out treatment by duodenoscope row calculus of bile duct).Frequently with therapeutic device be bile duct
Calculus stone extraction basket, the stone extraction basket pipe sheath being made of plastics inside are installed with drawing steel wire, and take with what drawing steel wire was connected
Stone mesh basket handle and stone extraction basket are constituted.
Existing stone extraction basket can only the calculus of bile duct to a certain size carry out taking stone, have a single function, if the knot of patient
Stone is not of uniform size, needs to repeat repeatedly to take stone, takes Shi Douhui that patient is allowed to endure torment to the fullest extent every time；
Also, when existing stone extraction basket enters patient's body enteron aisle, because enteron aisle is bent, it is difficult to lead stone extraction basket
To being not easy to take what stone operated to go on smoothly, can't bear patient suffering；
Therefore, it is necessary to make improvement to the prior art.
Utility model content
In order to overcome the drawbacks of the prior art, the utility model provides a kind of biliary tract stone extraction basket, realizes each entrance
The stone extraction basket of patient's body extracts various sizes of calculus simultaneously, reduces stone extraction basket and enters patient's body to calculus
Extract number, convenient for take stone operate go on smoothly, mitigate the pain of patient.
In order to achieve the above object, the utility model adopts the following technical solution realizes:
A kind of biliary tract stone extraction basket, including core bar, stretch ring, drag-line, epitheca and stone extraction basket, the stretch ring setting exist
It on the core bar, and is fixedly connected by the drag-line with mesh basket, the mesh basket is made of three steel wires, and three steel wires two are double
Welding is closed, forms three mesh basket silks, the end of three mesh basket silks is accommodated in described outer intrathecal, and three mesh basket silks are two-by-two
Adjacent to constitute three regions for extracting calculus, flexible net is arranged in two of them region, and target seeker is arranged in the mesh basket end, described
Spring is arranged in the end of target seeker.
Preferably, silica-gel sphere is arranged far from target seeker one end in the spring, and the silica-gel sphere is rectangle, is with spring
Symmetry axis is symmetrical arranged.
Preferably, the silica-gel sphere replaces with air bag, and the air bag is ellipse.
Preferably, the flexible net includes the spandex wire mesh of track and column braiding, and the wire mesh is welded in mesh basket silk.
Preferably, the size of mesh opening ratio of the wire mesh in described two regions is 1:2-5.
Compared with the nearest prior art, the technical solution of the utility model has the following beneficial effects:
Biliary tract stone extraction basket provided by the utility model, the mesh basket are made of three steel wires, and three steel wires are overlapped two-by-two
Screw up in twisted shape in together, forming three mesh basket silks, the end of three mesh basket silks be accommodated in it is described outer intrathecal, described three
Root mesh basket silk is adjacent two-by-two to constitute three regions for extracting calculus, and flexible net is arranged in two of them region, so that lithotomy net
It when basket enters patient's body every time, realizes and various sizes of calculus is extracted simultaneously, reduce stone extraction basket and enter patient's body
It is interior that number is extracted to calculus；Target seeker is arranged in the mesh basket end, and spring is arranged in the end of the target seeker, to lithotomy net
Basket is oriented to, and convenient for taking going on smoothly for stone operation, mitigates patient suffering.

Specific embodiment
The technical solution of the utility model is described further with reference to the accompanying drawing:
A kind of biliary tract stone extraction basket as shown in Figs. 1-2, including core bar 1, stretch ring 2, drag-line 3, epitheca 4 and stone extraction basket
5, the stretch ring 2 is arranged on the core bar 1, and is fixedly connected by the drag-line 3 with mesh basket 5, and the mesh basket 5 is by three
Steel wire composition, three steel wires are overlapped welding two-by-two, form three mesh basket silks 6, and three mesh basket silks 6 are adjacent two-by-two to constitute three
Flexible net 7 is arranged in region, two of them region, and the end of three mesh basket silks 6 is accommodated in the epitheca 4, the mesh basket 5
Target seeker 8 is arranged in end, and spring 9 is arranged in the end of the target seeker 8.
As a preferred embodiment, the softness in order to guarantee 9 end of spring, thus to entering patient
When intracorporal stone extraction basket 5 is oriented to, mitigate the pain of patient, as shown in figure 3, the spring 9 is arranged far from target seeker one end
Silica-gel sphere 10, the silica-gel sphere 10 are rectangle, are symmetrical arranged with spring 9 for symmetry axis.
As a preferred embodiment, in order to further enhance the softness of 9 end of spring, as shown in figure 4,
An air bag 11 is arranged far from one end of target seeker 8 in the spring 9, and the air bag 11 is rectangle, with spring 9 for symmetry axis pair
Claim setting.
