Abstract
The invention relates to an auxiliary device for removing biliary calculi through negative pressure suction. The auxiliary device for removing the calculi comprises a calculi wrapping device, a fixed seat and a stabilizing device. The alculus wrapping device is located at the near-end of the fixed seat, and the stabilizing device is reflexed on the peripheral surface of the far-end of the fixed seat. The calculi wrapping device is formed by latex and is in a skirt hemline shape. The fixed seat is made into a cylindrical transparent cap by utilizing soft or hard transparent silica gel or a rubber conduit. The stabilizing device forms an annular columnar sleeve by utilizing latex. The auxiliary device has the advantages that compared with a conventional choledochoscope calculi removing net basket, the auxiliary device genuinely achieves effects of being visible and being capable of being taken; by applying the device for removing the calculi through negative pressure suction, the biliary tract inner wall is not damaged easily, and the device is more minimally invasive; against some calculi which is difficult to take or is incarcerated, by the matching of the use of the conventional net basket, the calculi is taken more easily, and more time is saved; a disposable negative pressure suction rubber tube is combined with a conventional choledochoscope, and the auxiliary device is simple, economic, practical and easy to popularize and can be widely applied to the calculi surgery against, e.g., biliary calculi and urinary calculi.
Description
Technical field
The present invention relates to technical field of medical instruments, specifically, it is a kind of vacuum suction biliary tract stone extraction auxiliary device.
Background technology
Biliary Calculi is the common disease in surgery, and the calculus in common bile duct can cause obstruction of biliary tract secondary jaundice, gallbladder
The scorching even pancreatitiss threat to life of pipe.Operation is the unique method treating this disease.Choledochoscope takes stone to be that current surgery is conventional and controls
Treat a kind of method of Biliary Calculi, in the process, generally place fiber endoscopy along biliary tract cutting section, after finding calculus, use
Lithotomy net extracts calculus.But the method has the following disadvantages and defect.
1. choledochoscope finds calculus, easily occurs operation scenario to disappear, support with lithotomy net indigo plant when being extracted with lithotomy net indigo plant
And when calculus or biliary tract wall, counteracting force makes camera lens retreat, and causes operation scenario to disappear, often needs repeatedly to adjust；
2., when inserting lithotomy net indigo plant, apopore flow velocity is slack-off, and the visual field is unclear often；
3., when biliary tract caliber is thinner (for example: calculus of intrahepatic duct), basket with netting on top release is difficult, is difficult to entangle calculus, time-consuming and
Easily failure；
4. repeatable operation damages biliary tract inwall；
5. blue placement of lithotomy net acquires a certain degree of difficulty in actual clinical work with successfully taking stone, and skilled grasp needs certain time
Learning curve.
Chinese patent literature cn201220180407.3, applying date 2012.04.26, patent name is: a kind of novel biliary tract
Take stone sacculus, disclose a kind of novel biliary tract and take stone sacculus.Including conical nose, sacculus, pipe shaft, strengthen steel wire, connector.Its
In, sacculus is fixed on distal end of catheter position, using being front in deflated state.Sacculus overall structure is fast-swap, and sacculus is near
There is a fluid-through chamber opening at end, and pipe shaft includes reinforcement supporting steel wire, integrally pushes performance to improve conduit.Conduit hardness proximally arrives
Far-end presents decline trend, contributes to the conduction of push power.
Above-mentioned patent documentation mainly utilizes the dilatancy of sacculus, and calculus can take off along biliary tract under power effect in withdrawing of sacculus
Separate out.But with regard to combining with traditional fibre mirror, realize visible and desirable simple, convenient, safe stone taking device then
Not open.
In sum, need a kind of traditional fibre mirror badly to combine, realize visible and desirable simple, convenient, safe taking
Stone auxiliary device.And take stone auxiliary device to yet there are no report with regard to this.
