Description
Technical field
The present invention relates to a kind of Minimally Invasive Surgery instruments, and in particular to a kind of biliary tract continuously arranges stone device.The invention further relates to
The biliary tract continuously arranges the application method of stone device.
Background technique
Cholelithiasis be gall-bladder, in bile duct crystal concentration precipitating, if calculus is located at gall-bladder, be called cholecystolithiasis；Such as calculus
Positioned at choledochus, it is called choledocholithiasis.Women of the cholelithiasis in specific crowd is most common, such as U.S. original inhabitant.Cholelith shape
At risk factor include advanced age, obesity, western diet and heredodiathesis.There is 20% to suffer from the U.S., the people more than 65 years old
Cholelithiasis, but it is most of asymptomatic.There is the people about more than 500,000 to do surgical operation every year and take stone, wherein most of is because going out
Existing symptom and operation of going.
The main component of most choleliths is cholesterol, is made of calcium salt.Contain a large amount of cholesterol in bile, leads to
Exist in liquid form under normal state, when bile cholesterol supersaturation, cholesterol becomes insoluble, by being precipitated in bile
Precipitate into stone.
Most of choleliths are formed in gall-bladder, and from most of calculus of bile duct move by gall-bladder.Calculus in bile duct
Be formed as bile flow velocity it is slack-off, be retarded by silt and cause, as bile duct has narrow or postcholecystectomy.
Choledocholithiasis can lead to serious, threat to life choledochus infection (cholangitis), pancreatitis or liver inflammation.
When biliary system obstruction, bacterial reproduction forms bile duct inflammation rapidly, and bacterium can spread to blood flow and cause other positions of body
Infection.
The biliary tract stone extraction that modern times pass through is to implement ERCP (through duodenoscope retrograde cholangiopancreatography)+EST (scope nipple
Endoscopic sphincterotomy) stone-extraction operation, using biliary tract stone extraction basket, take the realization of the instruments such as stone air bag, lithotriptor is minimally invasive to take stone.But
It is that the operating method of existing calculus removing instrument is all first to protrude on the head of calculus removing instrument in biliary tract, clamps a coccolith head, then
Calculus removing instrument is taken out out of biliary tract together with stone, then biliary tract is protruded into on the head of calculus removing instrument again and clamps next
Stone.Therefore, existing calculus removing instrument can only a ground take, if biliary tract stone is very more, or using after lithotrity
Rubble is more, or belongs to silt shape calculus, especially because in cause specific biliary tract rubble or silt shape calculus cannot be natural
When discharge, using above-mentioned instrument, not only take stone operation it is relatively complicated, operation takes a long time, and calculus removing instrument need continually into
Human biliary duct out, it is easy to which interior tissue is damaged.

5th step starts driving motor, drives helical conveyor (4) low speed rotation in sheath；Aspirator is opened simultaneously,
Under the double action of the screw transmission strap (4) of the negative pressure and low speed rotation of aspirator, Biliary Calculi is moved upwards, through attracting interface
Biliary tract is sucked out in Biliary Calculi.
