Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with detailed description of the invention also with reference to accompanying drawing, this utility model is further described.Should be appreciated that, these describe just exemplary, and do not really want to limit scope of the present utility model.In addition, in the following description, the description to known features and technology is eliminated, to avoid unnecessarily obscuring concept of the present utility model.
Detailed description of the invention one: shown in composition graphs 1, comprises circular platform type groove 1, high pressure resistant dilating catheter 2, folded form is seamless sacculus 3, breast is convex 4, axle core 5, dye injection device 6, dye injection device conduit 7, hydralic pressure gauge conduit 8, hydralic pressure gauge 9, pressure regulator valve 10, sacculus lobe 11, dilating catheter wall 12, seal wire 13, conductive filament head 14, graduation mark 15; Circular platform type groove 1 is tubular, and its small end face inserts one end of high pressure resistant dilating catheter, and large end face outwardly; On the high pressure resistant dilating catheter 2 of circular platform type groove 1 small end face, connect the seamless sacculus 3 of folded form, folded form ball is seamless, and capsule 3 has sacculus lobe 11, sacculus lobe 11 surface distributed breast convex 4; Axle core 5 is hollow flexible pipe, inserts high pressure resistant dilating catheter 2 inside and stretches out; Seal wire 13 inserts in axle core 5 and conductive filament head 14 stretches out circular platform type groove 1; The other end of high pressure resistant dilating catheter 2 installs hydralic pressure gauge 9; Stretch out axle core 5 end of high pressure resistant dilating catheter 2 and the seamless link of dye injection device conduit 7; The other end of dye injection device conduit 7 inserts the injection port of dye injection device 6; Hydralic pressure gauge conduit 8 gos deep into axle core 5, and one end is inserted in hydralic pressure gauge 9, and the other end is connected with pressure regulator valve 10; Graduation mark 15 is carved with on the surface of the high pressure resistant dilating catheter 2 of pressure regulator valve 10 one end; Dilating catheter wall 12 is coated with water wetted material; Folded form is seamless, and sacculus 3 is made up of half compliant balloon material, and it has 3 lobe sacculus lobes 11 fold clockwise, 3 lobe sacculus lobes 11 are in circumferentially 120 degree, interval distribution; Breast convex 4 is circular cambered surface, is non-uniformly distributed in sacculus lobe 11 surface; Seal wire 13 is made up of elastomeric material and is stretched out circular platform type groove 1 large port; Dye injection device 6 passes through dye injection device conduit 7 to high pressure resistant dilating catheter 2 internal injection developer solution (normal saline, contrast agent or the mixed liquor of the two).
Before using, first detect sacculus dilating catheter and whether have leakage, in dye injection device 6, add normal saline and be pushed in sacculus dilating catheter, closing pressure-regulating valve 10 pressurize, detect the seamless sacculus 3 of folded form and whether have leakage phenomenon, if not, normally can use, open pressure regulator valve 10, pull the piston of development syringe at night 6 by emptying for the normal saline in sacculus dilating catheter; During use, dilating catheter wall 12 is coated with water wetted material, reduces the frictional force with bile duct; Injected in sacculus dilating catheter by dye injection device 6 and develop night on a small quantity, promote high pressure resistant dilating catheter 2 and enter in bile duct, in axle core 5, seal wire 13 first contacts with calculus, and then circular platform type groove 1 contacts with calculus; In dye injection device 6, add developer solution, be injected in high pressure resistant dilating catheter 2 by dye injection device conduit 7 by developer solution, folded form is seamless, and sacculus 3 discharges, and sacculus lobe 11 is heaved, and breast convex 4 withstands bile duct by large for bile duct support, closing pressure-regulating valve 10 pressurize; Because bile duct support is large, promote high pressure resistant dilating catheter 2 when moving forward, circular platform type groove 1 greatly end withstands calculus and moves forward; Due to complications during bile duct, ball-bag dilation tube, not by the bile duct that radian is larger, regulates pressure regulator valve 10, and control the pressure in sacculus dilating catheter, pressure is also presented in hydralic pressure gauge 9, and bile duct supports greatly further, and calculus just can be released gallbladder pipe by circular platform type groove 1; Complete dredging bile duct, open pressure valve 10 pressure release, extract high pressure resistant dilating catheter 2 out bile duct.
Should be understood that, above-mentioned detailed description of the invention of the present utility model only for exemplary illustration or explain principle of the present utility model, and is not formed restriction of the present utility model.Therefore, any amendment made when not departing from spirit and scope of the present utility model, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.In addition, this utility model claims be intended to contain fall into claims scope and border or this scope and border equivalents in whole change and modification.
