Abstract
The utility model discloses a novel gallstone removing device, which comprises a conical head part, a net basket body, an outer sheath pipe, a connecting component, a Y-shaped valve and a torsion-control guide wire, wherein the conical head part, the net basket body and the torsion-control guide wire are sequentially connected into a whole to form a net basket system; the outer sheath pipe, the connecting component and the Y-shaped valve are sequentially connected into a whole to form a sheath pipe system; and the net basket system is nested in a cavity tract of the sheath pipe system, and can be pushed forwards and backwards and rotate by the torsion-control guide wire. The net basket body adopts a laser-engraved structure, and a far end thereof has a rather high mesh density for fixing the gallstone conveniently and protecting the gallstone from dropping in the withdrawing and hauling process; and a near end of the net basket body has a rather low mesh density for capturing the gallstone conveniently. The net basket body is high in stability and is unlikely to distort in the process of capturing the gallstone, so that the surgical success rate is increased and complications are reduced.
Description
Technical field
This utility model relates to technical field of medical instruments, is a kind of Novel biliary tract stone taking device, and this device is applicable to the liver inside and outside bile duct stone patient, in the endoscopic surgery process of being expert at, by this device calculus in the bile duct is taken out.
Background technology
Surgical diseases is divided apoplexy due to endogenous wind in China, and Biliary Calculi has higher sickness rate, newly increases the patient every year and reaches millions of, and the Biliary Calculi disease is brought very large misery to patient.Treatment means is divided into two kinds at present, and is a kind of for to get stone by operative Modality, and this mode is cut patient's the tissues such as bile duct by surgical operation, behind the arrival stone location calculus taken out, and operation wound is larger, and patient's restore cycle is long, and expense is high; Another kind of mode is for passing through endoscopic technic, dedicated conduits is arrived the bile duct position by duodenum, with devices such as sacculus, baskets calculus is taken out again, this mode wound is little, it is fast that the patient recovers, but the operation requirements to the doctor is higher, but along with the progress of technology, increasing patient accepts Wicresoft and gets the stone operation.
When getting the stone operation by the capable Wicresoft of scope, the main lapicide's tool of getting is basket, and generally, basket is the helicoidal structure that several tinsels form, before use compression enters in the sheath pipe, be placed on the stone location far-end under the scope guiding, after the sheath pipe was withdrawn, basket discharged and is opened into netted, by the doctor at the external control seal wire that pulls and rotate basket, calculus can be received in the basket, and further withdraw out external, also can by laser or machinery mode calculus is pulverized.
The key of this operation is to catch calculus by basket rapidly and accurately, and in withdrawing the process that pulls calculus, calculus can be fixed in basket, and from basket, do not drop away, otherwise operating time is long, and the calculus secondary comes off, and easily causes related complication.In the design of basket, increase the capture rate to calculus, and more stable basket structure is provided, can significantly improve the success rate of this operation, shorten operating time.
Summary of the invention
The purpose of this utility model provides a kind of Novel biliary tract stone taking device.The problems such as solve basket that prior art exists and withdraw that calculus comes off in the process, and the basket structural instability, mesh is larger, and capture rate is low.
To achieve these goals, this utility model adopts following technical scheme:
A kind of Novel biliary tract stone taking device comprises conical nose, the basket body, and the epitheca pipe, connector, Y-valve is turned round the control seal wire.Wherein, conical nose, basket body and turn round the control seal wire and connect as one in turn form the basket system; Epitheca pipe, connector and Y-valve connect as one in turn, form the sheath guard system; The basket system is nested in the sheath guard system tract, can promote and rotation before and after turning round the control seal wire.
This Novel biliary tract stone taking device, described basket body are that NiTi tubing forms by laser engraving, are asymmetric network structure, and distal portions is the Z-type structure, has closeer mesh, and proximal part is 3-6 root support bar, have the mesh of dredging.
This Novel biliary tract stone taking device, described epitheca pipe is the multi-lumen tube of 5F-7F, has 1-3 inner chamber.
This Novel biliary tract stone taking device, described epitheca pipe are that the PTFE material forms, and have 0.15 millimeter-0.25 millimeter wall thickness.
This Novel biliary tract stone taking device is provided with 1-3 developing mark on the described epitheca pipe.
This Novel biliary tract stone taking device, described conical nose are that the PU material forms, and hardness is 70A-90A;
This Novel biliary tract stone taking device, described conical nose are that the PU material forms, and be preferred, adds 25%-50% barium sulfate component in the PU material, has preferably development effect.
This Novel biliary tract stone taking device, the described control seal wire of turning round, length is 1 meter-3 meters, distal site by glue bonding or the welding mode and an end of basket body fix.
The utlity model has following beneficial effect:
The basket body is the laser engraving structure, and far-end has higher mesh density, is convenient to fixedly calculus, is withdrawing and is pulling in the process, and the protection calculus can not deviate from.The nearly section of basket has the mesh density of dredging, and is convenient to catch calculus.The structure of the laser engraving of basket body has higher stability, in catching the calculus process, is not easy to distort, thereby improves the success rate of operation, reduces complication.
Conical nose can guarantee that the basket system in vivo in the course of conveying, by sick position, does not destroy the in-vivo tissue structure, thereby avoids the generation of complication smoothly.The PU material of conical nose is convenient to develop in art with 25%-50% barium sulfate component, makes things convenient for the doctor to operate, and shortens operating time.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Wherein, 1 is conical nose, and 2 is the basket body, and 3 is the epitheca pipe, and 3-1 is developing mark, and 4 is connector, and 5 is Y-valve, and 6 for turning round the control seal wire.
Fig. 2 is this utility model basket system income sheath guard system schematic diagram.
The specific embodiment
Now in conjunction with the accompanying drawings and embodiments utility model is further described.
As shown in Figure 1 and Figure 2, a kind of Novel biliary tract stone taking device comprises conical nose 1, basket body 2, and epitheca pipe 3, connector 4, Y-valve 5 is turned round control seal wire 6.Wherein, conical nose 1, basket body 2 connects as one in turn with turning round control seal wire 6, forms the basket system; Epitheca pipe 3, connector 4 connect as one in turn with Y-valve 5, form the sheath guard system; The basket system is nested in the sheath guard system tract, can promote and rotation by turning round control seal wire 6 front and back.
