Description
Technical field
The present invention relates to technical field of medical instruments, specifically, it is that a kind of liver transplantation takes pin device with simple portal vein.
Background technology
Liver transplantation is the most effective operation method of Current therapeutic End-stage liver disease and early hepatocarcinoma.Orthotopic liver transplantation scope
Greatly, the persistent period is long, is related to that internal organs, pipeline are many, is one of surgery operation the most complicated.Accept liver transplantation most of patients because
Liver cirrhosis, portal hypertension, lead to Portal Blood Flow to slow down or form reverse blood flow, some patientss are excised because of liver cirrhosis hypersplenism
Spleen, these factors easily promote the formation of Portal Vein Thrombosis.With the liver-transplantation patients of Portal Vein Thrombosis, in operation process
Portal Vein Thrombosis must completely be taken out, just can ensure that graft and patient's survival.Clinically specially effectively do not take bolt at present
Instrument, takes and commonly uses the routine operation apparatus such as surgical forcepss, oval tweezer during bolt, takes that bolt success rate is low, difficulty big, often will repeatedly take
Bolt, when taking bolt every time, blood loss is big, and liver-transplantation patients often have thrombin dyssynthesis, often repeatedly take bolt in orthotopic liver transplantation
Greatly increase amount of bleeding, blood coagulation substance loses exhaustion in a large number, then DIC occurs, ultimately result in graft failure.
Several features below liver cirrhosis Portal Vein Thrombosis：1st, often to form the time longer for thrombosis, and white, matter are tough；2nd, thrombosis
Often there is boundary with portal vein inner membrance, can blunt separation；3rd, thrombosis and blood vessel wall completely disengage from and could completely take out thrombosis.
In sum, need a kind of device badly simple, reduce bleeding, and disposably can completely take out the door of Portal Vein Thrombosis
Vein takes pin device, and takes pin device have not been reported with regard to this at present.
Content of the invention
The purpose of the present invention is for deficiency of the prior art, provides a kind of simple portal vein of liver transplantation to take bolt to fill
Put.
For achieving the above object, the present invention adopts the technical scheme that：A kind of liver transplantation takes pin device with simple portal vein,
It is characterized in that, the described pin device that takes is provided with thrombosis snare, thrombus separator, and described thrombosis snare is provided with thrombosis circle
Set, lock, barb, hollow pipe, described lock is arranged on the afterbody of thrombosis snare, and described barb is arranged on lock inside,
Described thrombosis snare head passes through lock, and described hollow pipe is inserted in the head of thrombosis snare, and described hollow pipe one end sets
There is ring, described thrombosis snare head is connected with ring, described thrombus separator is hollow structure.
Described latch as unidirectional lock.
Described barb shape is triangle.
Described hollow pipe material is plastics.
Described hollow pipe diameter is less than lock.
Described hollow pipe two ends are trapezoidal round platform.
Described thrombus separator head circle is blunt.
Described thrombus separator material is metal.
Described thrombus separator diameter range is 8-16mm.
The a diameter of five kinds of specifications of 8mm, 10mm, 12mm, 14mm, 16mm of described thrombus separator.
The invention has the advantages that：
1st, device is simply it is easy to produce and large-scale promotion.
2nd, easy to use it is easy to operation.
3rd, reduce the bleeding in operation, disposably can completely take out Portal Vein Thrombosis.
