Description
Technical field
The utility model discloses a kind of lower common bile duct occluding devices, belong to surgical operation auxiliary appliance technical field.
A kind of achievable lower common bile duct flow blocking is referred specifically to, a large amount of flows in complexity calculus of intrahepatic duct patient with operation art are reduced
Into in art caused by enteron aisle and the device of postoperative complications.
Background technology
Complexity calculus of intrahepatic duct is China's common disease frequently-occurring disease, Chang Jifa infection of biliary tract repeatedly, liver function damage, more
Severe patient needs row orthotopic liver transplantation.Biliary tract stone extraction be at present it is main for complexity treating hepatolithiasis method it
One.
It is found in biliary tract stone extraction operation is clinical, the usual state of an illness of stones in intrahepatic bile duct Calculus patient is complicated, through biliary tract fistula
It takes stone often to need to perform the operation several times and can just exhaust calculus in pipe, and needs expansion bile ducts of largely washing by water during taking stone, and it is a large amount of
A series of complication of patient can be led into intestinal tube by washing by water.Such as 1. the hypertonia of bath in art enter ductus pancreaticus and lead to pancreatitis；2. suffering from
Person's abdominal distension has to terminate operation in advance；3. diaphram raises the influence to respiratory system, cardiac function；Continue 4. water flows through stomach tube
Outflow causes accidentally to inhale possible；5. hypothermia leads to fever even general infection of shivering.Patient it is postoperative influence include：1. pain,
Diarrhea increases the ailing sense of operation and fear；2. nipple muscular function is impaired, intestinal juice, which backflows, causes biliary tract retrograde infection；3. irritability
Wound increases；4. bacterial translocation from gut, imbalance caused by a large amount of water-filling expansions of intestinal tube；5. water intoxication, electrolyte disturbance.And for pre-
The case where preventing such complication, there is no effective solution method.
Utility model content
For the above-mentioned deficiency of the prior art, the purpose of this utility model is intended to provide a kind of lower common bile duct blocking dress
It sets, including conduit and sacculus portion, tube at one end is equipped with fluid injection end, and the conduit other end is connected to sacculus portion, and the sacculus portion includes
Straightway and tilting section, straightway connecting tube, the lower common bile duct occluding device further include liquid injection pipe and thread eye, described
Liquid injection pipe is passed through from conduit, and liquid injection pipe one end connects fluid injection end, and the liquid injection pipe other end extends to inside sacculus portion, described to lead
Wire hole is arranged inside sacculus portion.
Further, the conduit cross section is ellipse, is about 30cm.
Further, the thread eye is arranged along sacculus portion length direction and thread eye is arranged at sacculus cross section center
Position.
Wherein, a diameter of 0.5mm of the thread eye.
The beneficial effects of the utility model are：A kind of lower common bile duct occluding device of the utility model, takes in biliary tract
It is used in stone operation, the device of the utility model is placed in water-filling dilating sacculus after lower common bile duct, makes choledochus epimere flow
Enteric cavity will not be flowed downwardly into, reduces the interference to enteron aisle, while avoiding the generation of abdominal distension.
Using the device of the utility model, advantageous effect is apparent：
1. keep upper digestive tract because hydrochloric acid in gastric juice there are due to the opposite germ-free condition that keeps.Avoiding a large amount of flows from entering intestinal tube causes
Bacterial translocation from gut caused by dilatation of intestine, flora imbalance.
2. mitigating the reflux infection caused due to the hepatocytes secrete pressure caused by flow is excessive is damaged.
3. for the case where there are infection of biliary tract in the case of Biliary Calculi most patients, the method, which can be reduced, will infect bile
And cholelith pours the further infection caused by intestinal tube.
4. reducing the Common openings of immense pressure impact lower common bile duct and ductus pancreaticus, the generation of pancreatitis is avoided.
5. reducing postoperative antibiotic usage.
6. water dispenser flow velocity can be reduced, it can achieve the purpose that expanding stones in intrahepatic bile duct takes stone using lower perfusion water flow velocity,
Reduce water waste.
7. applying distal common bile duct flow interrupter technique, the generation of intraoperative compliaction is reduced, can be that stone is taken to strive for more
Time.
8. minimum guiding theory is interfered to patient body with operation method, by minimally invasive surgery Idea, Promote a to new peak
Degree.
It using the device of the utility model, can reduce to corrective surgery wound, reduce patient and complication occurs, reduce patient
Hospital stays has very high application value in clinical practice.

Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further：
Lower common bile duct occluding device provided by the utility model, as shown in Figure 1 and Figure 2
In the present embodiment, a kind of lower common bile duct occluding device is provided, used in taking stone to perform the operation in through biliary tract fistula,
It is expanded by water-filling and blocks choledochus epimere flow, choledochus epimere flow is made not flow downwardly into enteric cavity, reduce surgical procedure
In interference to enteron aisle, while avoiding the generation of abdominal distension, reduce the generation of complication for patients.
Specifically, lower common bile duct occluding device, including the be interconnected conduit 1 of length 30cm and the sacculus of length 3cm
Portion 2, sacculus portion 2 include straightway 6 and tilting section 7 in the longitudinal direction, and straightway connecting tube 1, tilting section 7 is as sacculus portion
2 end is set as skewed, is adapted with the physiological structure of lower common bile duct.In one end of conduit 1, fluid injection end 3 is set,
Fluid injection end 3 can refer to conventional catheter balloon design, including liquid injection port and one-way cock, and the injection that can be lived by water filling is other
Liquid beats sacculus portion 2 of rising.The other end of conduit 1 extends to inside sacculus portion 2.
Sacculus portion 2 is due to the position of sacculus to be retained, so diameter is wider, conduit 1 takes stone due to space to be saved
Operation, therefore design flat ellipse.The changeover portion between conduit 1 in sacculus portion 2 be 45 ° of inclined-planes, convenient for operation after take out
Sacculus, while not damaging biliary tract.
As shown in figure 3, to keep device durable, while smaller sinus space is occupied, take stone to operate conducive to subsequent,
In the present embodiment, the cross section of conduit 1 is preferably arranged to ellipse.
It is led in the present embodiment as shown in figure 4, being provided in the center in sacculus portion 2 for penetrating the thread eye 5 of seal wire
