Description
Technical field
The utility model belongs to the field of medical instrument technology more particularly to a kind of belt carcass puncture needle component.
Background technique
Puncture is a medical surgery term, be will puncture be needled into body cavity extract secretion chemically examine, to body cavity inject
Gas or contrast agent do contrast examination, or into body cavity injection of medicine a kind of Clinics.The purpose of puncture is blood test,
Blood transfusion, infusion and merging conduit do angiography.
Obstructive jaundice common disease factor has cholangiocarcinoma, cholelithiasis etc., and often disease time is longer by such patient, but body
The mesh xanthochromia time is shorter, is frequently accompanied by liver function damage.Percutaneous transhepatic cholangiography and drainage art (PTCD, percutaneous
Transhepatic cholangial drainage) there is help meaning for such patient.It is clinically common at present
PTCD art usually uses one-step method puncture technique, and such method has many advantages, such as short without exchange, puncture time.But it is punctured
Device also has the shortcomings that certain.
In the sting device of existing step puncture method, puncture needle is hollow tubular structure, allows contrast agent
And seal wire can smoothly enter into biliary tract.But hollow tubular structure can also cut liver organization strip, on the one hand this tissue can block up
Puncture needle is filled in, on the other hand cutting damage can be generated to liver, when puncture channel is there are when artery and portal vein, be easy to produce
Dynamic-portal vein leakage, artery-bile duct leaks, portal vein-bile duct leaks etc. lead to the generation for even aggravating postoperative complications, are patient's
Health, the later period of operation, which replys, brings huge security risk.
Utility model content
To solve the above problems, the utility model provides a kind of belt carcass puncture needle component, comprising:
External puncture needle and removable needle core；

It is above-mentioned, it should be noted that Fr is the unit of conduit, is the unit for measuring perimeter originally, is a Charles Robert Richet
Utility model, for writing a Chinese character in simplified form for English French.That the subsequent number of Fr represents is Zhou Jing, as Fr16 indicates that Zhou Jing is 16Fr.
Because of 3F=1mm weeks diameter, 1/3 week diameter ≈ 0.33mm of F ≈.1/3 week diameter=F × week of Zhou Jing=π (3.14) × diameter, diameter ≈
Diameter/1mm.Conduit diameter=16 × 0.33 ≈ 5.3mm of Fr16 can be calculated according to this.In the present embodiment, 5Fr, as
Zhou Jing is 5Fr, and conduit diameter is about 1.65mm.
Above-mentioned, extension base is equipped with shackle member 133, is clamped for shackle member 133 and the counnter attack valve 125, in addition,
It can achieve a fixed connection by other means with counnter attack valve 125, for example, can be threaded connection.
Above-mentioned shackle member 133, may include manually opening knob, after shackle member 133 and counnter attack valve 125 are clamped, lead to
It crosses and presses unlatching knob, to shackle member 133 be separated with counnter attack valve 125, by opening knob, it can be achieved that singlehanded for clamping
The separation of part 133 and counnter attack valve 125 improves the efficiency of dismounting, provides convenience for surgical work.
Above-mentioned, the outer diameter of expander 13 and the outer diameter of puncture needle component are respectively less than the internal diameter of catheter sheath 12, so expander
13 and puncture needle component can penetrate in the catheter lumen 124 of catheter sheath 12；Puncture needle component can penetrate the expansion of expander 13
In chamber 134.
Above-mentioned, expander 13 plays the role of support and increases intensity, and often skin is harder by xanthochromia patient, so in this reality
In novel, the expander 13 that a kind of outer diameter is less than 122 internal diameter of sheath is provided, can combine the expander 13 with sheath 122, and
The puncture needle component is penetrated in the expansion cavity 134 of the expander 13 after the combination, as, constitutes one from the inside to the outside
The respectively combination of puncture needle component, expander 13, catheter sheath 12, as a whole by the combination, to be led along seal wire 113
Enter target bile duct.
Above-mentioned, the material of expander 13 can include but is not limited to polypropylene, and coating is silicone oil, dimethylacrylamide-
Epihydric alcohol acrylic ester copolymer.Catheter sheath 12 is disposable product, ethylene oxide sterilizing.
In order to better illustrate belt carcass puncture needle component 11 provided by the utility model, the utility model also provides one kind
The puncture procedure method of belt carcass puncture needle component 11, comprising:
1, after selecting puncture site, the anesthesia of routine disinfection drape；
2, percutaneous liver is punctured, and is worn after target bile duct using 18G belt carcass puncture needle component 11, is exited needle core, Bian Hou
Puncture needle side radiography is moved back, after radiography confirmation is punctured to target bile duct, places 0.035 short-length guidewires 113 through puncture needle under DSA perspective
To target position, puncture needle is exited；
3,5Fr sheath 122 and expander 13 are imported into target bile duct as a whole along seal wire 113；Xanthochromia patient's skin
Skin is often harder, puncture needle, expander 13 and sheath 122 can be imported target bile duct along seal wire 113 as a whole.
4, expander 13 is released, seal wire 113 and sheath 122 are retained, sheath 122 is confirmed by 123 radiography of side pipe at DSA
Position and Intrahepatic Bile Duct Dilation situation；
5, outer diameter≤5Fr conduit or other treatment instrument can be introduced directly into through sheath 122；
Outer diameter is greater than the conduit or other treatment instrument of 5Fr, must will import sheath 122 and take out, retain seal wire 11313, edge
The sheath 122 or other treatment instrument of the importing larger diameter of seal wire 113；
6, it after the completion of performing the operation, takes out seal wire 113 and imports sheath 122.
