Abstract
The utility model relates to a that takes elbow gets stone basket improves on the basis of stone basket is got to the tradition, and it mainly is applicable to therapeutical liver and gall pipe disease, belongs to the medical instrument field. The utility model discloses a basket, push -and -pull rod, tube sheath, seeker, the basket top is connected with the seeker of elbow structure, and the other end is connected with the top of push -and -pull rod, and the basket is wrapping up tube sheath with the skin of push -and -pull rod, and the end of push -and -pull rod links to each other with operating handle. The utility model discloses can convenient and fast and accurate guide basket get the stone operation in getting into the bile duct, not only accelerated operation speed, shortened patient's the painful time, simultaneously also greatly increased to patient's safe coefficient, application effect is good.
Description
Technical field
This utility model relates to a kind of medical treatment apparatus, particularly gets the basket of calculus in bile duct, is applicable to treat hepatobiliary disease.
Background technology
Usually, suffer from the patient of common bile duct, common hepatic duct, left and right hepatolith, usually there will be the clinical symptoms such as diarrhoea, obstructive jaundice and heating.For the patient being reluctant to operate or have operation taboo, recurrence after operation, postcholecystectomy etc., treatment ERCP (namely taking out treatment by duodenoscope row calculus of bile duct) is adopted to be first-selection.The therapeutic device of normal employing is net basket for fetching gall-stone, and the stone extraction basket pipe sheath be made of plastics, is installed with tractive steel wire in it, and the stone extraction basket handle be connected with tractive steel wire and stone extraction basket are formed.But the front end of the general stone extraction basket for biliary tract stone extraction does not have special handling, not often very smooth and easy in the process inserting biliary tract, because acutangulate between duodenum and common bile duct, therefore be easy to stone extraction basket is mistakenly inserted in ductus pancreaticus, add operating time, cause unnecessary potential safety hazard.
Summary of the invention
This utility model object is the defect overcoming conventional stone extraction basket, as inserted in bile duct process shortcomings such as having some setbacks, this utility model provides a kind of stone extraction basket with elbow of improvement, can carry out fast and accurately in bile duct, getting stone operation, accelerate operation progress, shorten the painful time of patient.
Technical solution adopted in the utility model is: a kind of stone extraction basket with elbow, comprise basket, push-pull bar, pipe sheath and target seeker, the top of described basket is connected with the target seeker of elbow structure, the other end of basket is connected with push-pull bar head end, the outer layer covers of basket and push-pull bar has pipe sheath, and the end of push-pull bar is connected with operating grip.Described basket is in income pipe sheath when not working, and operationally basket is driven outside protruded tube sheath by operating grip and push-pull bar co-operate.
Preferably, described basket is that common basket commonly uses medical material as stainless steel silk or Nitinol, and the twine quantity of basket can be 4, also can be 8, for spherical after basket struts.
Preferably, the target seeker of described elbow structure is long is 6-7mm, and angle of bend is 135 °, and target seeker is identical with pipe sheath diameter at the diameter near basket end, and along with away from basket end, target seeker diameter is tapered.
Preferably, the material of described push-pull bar is identical with basket, and pipe sheath is polytetrafluoroethylmaterial material.
Preferably, the target seeker of described elbow structure is X-radiopacity polyurethane developing material or the polypropylene material containing metallic addition.
The beneficial effect that produces of technique scheme is adopted to be: to carry out getting stone operation in the bile duct that the arranging of the target seeker of elbow structure can make basket enter in acute angle between duodenum accurately, easily and efficiently, avoid stone extraction basket and be easily mistakenly inserted the unnecessary risk caused in ductus pancreaticus; Meanwhile, the target seeker of elbow structure is the macromolecular material of X-ray opaque line, in ERCP, therefore still can guide the trend of basket.The target seeker of this utility model band elbow structure, can be convenient and swift and guide basket to enter in bile duct accurately to carry out getting stone operation, not only accelerate operative speed, shorten the painful time of patient, also considerably increase the safe coefficient to patient, effect is good simultaneously.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
A kind of stone extraction basket with elbow as shown in Figure 1, mainly comprises basket 1, push-pull bar 2, pipe sheath 3, target seeker 4.Basket 1 top is connected with the target seeker 4 of elbow structure, and target seeker 4 is long is 6-7cm, and angle of bend is 135 °, identical with pipe sheath 3 diameter at the diameter near basket 1 end, and along with away from basket 1 end, target seeker 4 diameter is tapered.The target seeker 4 of elbow structure is X-radiopacity polyurethane developing material or the polypropylene material being mixed with metallic addition.The other end of basket 1 is connected with the top of push-pull bar 2, basket 1 is identical with the material of push-pull bar 2, is medical material as stainless steel silk or Nitinol, and basket 1 has pipe sheath 3 with the outer layer covers of push-pull bar 2, pipe sheath 3 is polytetrafluoroethylmaterial material, has certain consistency and elasticity.The twine quantity of basket 1 can be 4, also can be 8, for spherical after basket 1 struts.Another basket 1 struts shape and also can be diamond, spiral type.The end of push-pull bar 2 is connected with operating grip.Basket 1 is in income pipe sheath 3 in idle situation, and operationally basket operates protruded tube sheath 3 (as shown in Figure 2) by operating grip and common drive of push-pull bar 2.
As shown in Figure 3, when getting stone operation, basket is taken in pipe sheath by first control operation handle, by this utility model when duodenum inserts ductus choledochus, pipe shaft of the present utility model is rotated by regulating the sensing of elbow and coordinating under mirror, make elbow towards correcting aligning ductus choledochus, so by this utility model deeply, then elbow leads basket fast and the entering in ductus choledochus of safety.Continue deeply afterwards, when basket exceedes calculus, basket is opened and movable and rotation near calculus, make calculus enter basket, tighten up basket by operating handle, entangle calculus firm, under fluoroscopy stone extraction basket is together slowly pulled out together with calculus.
