Description
Technical field
The utility model relates to medical auxiliary apparatus, puncture more particularly, to a kind of percutaneous transhepatic cholangiography and drainage art
Device.
Background technique
Obstruction of bile duct is liver and gall surgical department's common disease, is a kind of higher disease of the death rate, Duo Shuoji in Surgical Acute Venter Diseases
It sends out caused by the lesions such as calculus of bile duct and cholangiocarcinoma.Percutaneous transhepatic cholangiography and drainage art (i.e. PTCD) is the weight for treating obstruction of bile duct
Treatment means are wanted, percutaneously penetrate stones in intrahepatic bile duct using puncture needle, then contrast agent is directly injected into biliary tract but extrahepatic duct
Development rapidly, while biliary drainage is carried out by angiography tube.Puncture needle is generally made of needle stand, syringe needle and needle core, puncture drainage
When generally use two-step method, i.e., the indwelling puncture needle needle core in puncture process, puncture needle extracts needle core out after reaching target, use
Syringe extracts bile, it is ensured that needle point enters by puncture needle indwelling seal wire after bile duct, then by seal wire indwelling drainage tube (if
It without bile in syringe, needs to puncture again, until bile can be extracted out in syringe).Above-mentioned puncture needle is primarily present following
Defect: can not confirm whether syringe needle enters bile duct during inserting needle, need inserting needle repeatedly, site of puncture is caused inflammation etc. occur
There is bleeding in complication or operative site, while increasing patient's slight illness;When placing seal wire again after extracting needle core, it is easy because puncturing
Needle is shaken and causing needle point to slip out of bile duct leads to puncture failure, reduces success rate of operation, increases operation risk.
Summary of the invention

Specific embodiment
As shown in Figure 1-3, percutaneous transhepatic cholangiography and drainage art puncture outfit described in the utility model, including piercing needle
1, it further include the syringe being made of syringe 2, piston 3, push rod 4, piercing needle 1 is arranged on 2 nipple of syringe, piercing needle 1
Needle stalk be hollow structure, be made of stainless steel material;Nipple is connect with syringe 2 by arc transition, the cream at syringe 2
Strip through-hole 5 is offered on head, and is attached with silk guide passage 6 on 2 side wall of syringe of 5 corresponding position of strip through-hole, seal wire is logical
Road 6 is connect with 2 nipple rounding off of syringe, can smoothly enter into seal wire in the pintle of piercing needle 1, and silk guide passage 6 extends to the right
To 2 middle part of syringe to the right position, the entrance of 6 right end of silk guide passage is provided with arcuate guide side, at arcuate guide side
Silk guide passage 6 in be provided with the rubber stopper 7 of through-hole is penetrated, be convenient for sealing injection device, gas avoided to enter, be conducive to negative pressure
It is formed, penetrates through-hole and pass through convenient for seal wire;
As shown in Figure 1 and Figure 2,2 right end of syringe is symmetrical above and below is provided with upper limit bit slice 8 and lower limit bit slice 9, upper limit bit slice 8 with
6 import of silk guide passage is correspondingly arranged, and seal wire entrance hole 10 and two seal wire fixation holes in a strip shape are offered on upper limit bit slice 8,
Two seal wire fixation holes are circumferentially uniformly arranged along seal wire entrance hole 10, and are connected with seal wire entrance hole 10, two seal wire fixation holes
Width is slightly less than the diameter of seal wire, and different rule are made in two seal wire fixation holes respectively when reality manufactures convenient for fixed seal wire
Lattice, to meet the needs of different-diameter seal wire, for convenient for difference, be printed on the upper limit bit slice 8 of seal wire fixation hole corresponding position
It is the diameters of fixed seal wire that seal wire specification, which marks 13();The diameter of seal wire entrance hole 10 is greater than the diameter of seal wire, so as to
It is passed through in seal wire, when puncture, seal wire successively enters in silk guide passage 6 through seal wire entrance hole 10, rubber stopper 7, then passes through
The strip through-hole 5 of 6 front end of silk guide passage enters in piercing needle 1, is finally pierced by out of piercing needle 1;It is arranged on lower limit bit slice 9
There is horizontal-extending positive stop strip 11 to the right, the limiting stand 12 for 4 drawing handle of block push rod is hinged on positive stop strip 11, limits
Platform 12 is two station limiting stands, limiting stand 12 be located at the inside of positive stop strip 11 and with 2 inside of syringe to it is corresponding when state, be used for
The drawing handle of block push rod 4, anti-throw-out lever 4 is slided to the front end of syringe 2, when A is turned out 90 degree to limiting stand 12 along Fig. 1
When (rotating counterclockwise 90 degree), limiting stand 12 deviates 2 inside of syringe, and limiting stand 12 is in non-limit state at this time, negative taking out
Pass through during pressure convenient for drawing handle.
When operation, piercing needle 1 is fixed on nipple, while seal wire is placed in silk guide passage 6 by seal wire entrance hole 10
Inner guide wire implantation site is advisable with being located on the right side of strip through-hole 5, then seal wire is fixed in seal wire fixation hole, and by seal wire tail
End is fixed;Then point of puncture is selected, after piercing needle 1 enters subcutaneous tissue, push rod 4 is pulled out and draws its drawing handle
It moves to limiting stand 12, syringe 2 is in continuous negative pressure state at this time, and piercing needle 1 penetrates target position under B-ultrasound
Place is set, after the needle point of piercing needle 1 enters bile duct, due to suction function, bile enters in syringe 2, operates doctor one at this time
Syringe 2 is held, the other hand releases seal wire out of seal wire fixation hole, and assistant takes advantage of a situation and pushes seal wire forward, and seal wire is from strip through-hole 5
It is pierced by from the needle point of piercing needle 1 after into piercing needle 1, seal wire is placed in bile duct, be then log out piercing needle 1, stay
Seal wire is set, drainage tube is placed in bile duct along seal wire, exits seal wire, puncture procedure finally is can be completed into drainage tube fixation;If note
Do not occur bile in emitter, only need to change syringe needle direction under ultrasound, is not necessarily to repeated puncture.
The advantages of the utility model major embodiment following aspect:
1, continuous negative pressure is provided, it is ensured that puncture in place: after piercing needle 1 is inserted into subcutaneous tissue, pulling back push rod 4 and lead to
It crosses limiting stand 12 to be limited, provides continuous negative pressure for puncture process, by observing whether bile enters confirmation puncture in syringe 2
Whether in place, without pull needle core syringe needle 1 can confirm whether puncture position is correct.
2, puncture procedure is simple, puncture success rate is high: penetrating piercing needle 1 in patient's bile duct when puncture, seal wire is through leading
Silk entrance hole 10, silk guide passage 6 are pierced by from piercing needle 1, and silk guide passage 6 has guidance position-limiting action to seal wire;It can before puncture
Seal wire is preferentially fixed on puncture outfit appropriate location by corresponding seal wire fixation hole, confirmation puncture needle enters in bile duct
Afterwards, seal wire can take advantage of a situation push-in, avoid causing piercing needle 1 to slip out of bile duct because of merging seal wire, and then avoid secondary puncture, together
When mitigate patient pain.
