Description
Technical field
This utility model relates to a kind of gallbladder ductus pancreaticus intracavity cytology brush.
Background technology
Gallbladder ductus pancreaticus intracavity cytological brushings is the pathological diagnosis important method that obtains gallbladder ductus pancreaticus malignant tumor, sometimes or even unique method.
In bile duct, in mamillary mucinous tumors and ductus pancreaticus, the sickness rate of mamillary mucinous tumors is increasing year by year.In gallbladder ductus pancreaticus, the feature of mucinous tumors is because tumor produces too much mucus and makes tube chamber without narrow expansion.Commitment in disease needs and chronic pancreatitis, cancer of pancreas, and Duodenal Papillary Carcinoma, distal common bile duct cancer is differentiated.In the middle and advanced stage stage, need to judge the progress stage of disease, with judging prognosis, determine therapeutic strategy, therefore obtain pathological diagnosis by stages most important to determine.
Although have per os electronics choledochoscope and SPYGLASS choledochoscope, because both biopsy ducts are quite little, can not pass through cytology brush.Per os electronics choledochoscope needs two skilled Inner mirror doctor operations especially, and enter gallbladder ductus pancreaticus with the form of primary and secondary mirror from the biopsy duct of duodenoscope, therefore can not be movable fully flexibly, can not adjust angle although can look at straight, can not be arbitrary near focus.The mirror hypograph definition of SPYGLASS choledochoscope is limited, and same existence can not be arbitrary near focus.Both are expensive, easily loss, and popularity rate is very low.Therefore cannot popularize as the method that obtains the pathological diagnosis of gallbladder ductus pancreaticus.
For this reason, the patent documentation that publication number is CN202960597U discloses a kind of biliary tract cytology brush, adopts double cavity structure, increase guidewire lumen, seal wire can guide through guidewire lumen, samples thereby arrive smoothly biliary tract stenosis position, and its brush adopts linear structure.Because gallbladder ductus pancreaticus is not always narrow, but the expansion of a lot of positions obviously, when focus is present in the gallbladder ductus pancreaticus wall of expansion, and not in the time of narrow gallbladder ductus pancreaticus wall, the cytology brush of linear type brush just can not touch the gallbladder ductus pancreaticus tube wall of this type of tumor, can only obtain the contact of the mesotropic mucus of pipe, and it is little to be suspended in tumor cell in mucus, is often not enough to clear and definite cytodiagnosis.So the cytology brush of linear type brush often can not be obtained effective specimen sampling.And, in sampling process, generally need rotational head to obtain more cell tissue sample, existing cytology brush can only rotate brush by rotating whole cytology brush apparatus and epitheca pipe, and operation easier causes greatly and easily the damage of patient's tract.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this utility model is to provide a kind of gallbladder ductus pancreaticus intracavity cytology brush, rotate driving wire and rotate the cell brush of far-end by runner, can realize the rotation that one-handed performance control cell brush is spent with respect to epitheca pipe 360, make operation more convenient, obtain tissue mass larger, there is simple in structure, the operation advantage such as reliable, easy to operate gently.
To achieve the above object, this utility model has adopted following technical scheme:
A kind of gallbladder ductus pancreaticus intracavity cytology brush, comprise hands handle, slide handle, epitheca pipe, driving wire and brush, the far-end of described driving wire is connected with brush, the near-end of driving wire is connected with the slide handle being slidably connected on handle, the sheathed epitheca pipe in described driving wire outside, the near-end of epitheca pipe is fixedly connected with handle, the near-end of described driving wire is arranged with runner, runner rotates and is arranged on handle, wherein, described slide handle can sliding axially along driving wire, described driving wire with the circumferential fixed axis of runner to not being fixedly connected with, described driving wire is not circumferentially fixed axial limiting with slide handle and is connected.Runner and driving wire can transmit and rotate and can relatively move, rotate driving wire and just can rotate like this cell brush of far-end by runner, can realize the rotation that one-handed performance control cell brush is spent with respect to epitheca pipe 360, make operation more convenient, obtain tissue mass larger, there is simple in structure, the operation advantage such as reliable, easy to operate gently.Above-mentioned driving wire is some steel wires or single-strand rope.Preferably individual wire or single-strand rope, to have good pliability and torsional strength.
As preferably, the near-end of described driving wire has been fixed by socket rigid conduit, rigid conduit with the sheathed circumferential fixed axis of runner on it to not being fixedly connected with.Conduit be have certain support strength, outer cross section is special-shaped pipe fitting, coordinates to realize transmitting and rotates and can move axially with irregularly-shaped hole on runner (cross or other non-circular), convenient installation simple in structure made.In addition, above-mentioned conduit can be adopted in this way with being connected also of runner: the irregularly-shaped hole in a newly-increased tumbler and runner matches, and conduit and tumbler are fixed.
As preferably, the near-end of described epitheca pipe is arranged with rigidity guide pipe, and described epitheca pipe and rigidity guide pipe are all affixed with handle.Guide pipe is bourdon tube thicker, that have certain support strength or rigid pipe, can avoid like this connecting portion fracture, guarantees the reliable mobile of conduit in epitheca pipe.
As preferably, the far-end of described epitheca pipe is fixed a head sheath pipe, and described brush comprises elasticity brush ring, and elasticity brush ring struts and is ellipticity under naturalness, and the both sides of elasticity brush ring distribute and are fixed with bristle.Adopt elastic annular brush-head structure, while use, can be contracted in head sheath pipe, when use, stretch out head sheath pipe and naturally open and be ellipticity, can be full of the tube chamber of whole expansion, therefore can touch the tube wall of expansion.Cytology brush brush, under the state not using, is contracted in head sheath pipe, when use, by promoting slide handle by outside cell brush release head portion sheath pipe, brushes inspection in pancreatic duct; Cell brush can naturally strut and be ellipticity, and width maximum can reach about 25cm left and right, can get more histiocyte at the very serious bile duct inwall brush of expansion, obtains effective specimen sampling, makes to test the maximization of positive rate.
As preferably, described elasticity brush ring is made up of stainless steel silk, nitinol alloy wire or the macromolecular material with resiliency supported performance.
As preferably, the front end of described elasticity brush ring is fixed with blunt nosed, and the rear end of elasticity brush ring is fixedly connected with driving wire.Snare Front-end Design has blunt nosed, after avoiding brush to enter body cavities, damages tissue, and blunt nosed can being made up of the medical material such as resin or metal is fixed on cytology brush head end by methods such as bonding or welding.
As preferably, described epitheca pipe is double lumen tube, and a tract is guidewire lumen, and another tract is current for driving wire, and head sheath pipe is single lumen catheter.Head sheath pipe and epitheca Guan Douwei macromolecular material are made; Head sheath pipe is fixed on epitheca pipe by methods such as bonding or pyrocondensations.
This utility model is owing to having adopted above technical scheme, runner and driving wire can transmit and rotate and can relatively move, rotate driving wire and just can rotate like this cell brush of far-end by runner, can realize the rotation that one-handed performance control cell brush is spent with respect to epitheca pipe 360, make operation more convenient, obtain tissue mass larger, there is simple in structure, the operation advantage such as reliable, easy to operate gently.
