Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to be implanted into Endobiliary drainage bracket through choledochoscope.
Background technique
Biliary drainage bracket refers to through scope to biliary tract rack is placed in patient body, is generally chiefly used in treating gall stone etc.
Illness, the post-operative recovery for extensive wound.
Existing biliary drainage bracket still has some shortcomings when in use: treatment choledocholithiasis is main at present
Two schemes, one kind is removing out choledocholithiasis by retrograde cholangiopancreatography art, and defect be to destroy this sphincter of Austria, and nothing
Method takes out intrahepatic calculi and cholecystolithiasis；Another kind is that exploration of common bile duct takes stone, T Tube Drain, and defect is that T pipe draws by stomach wall
It is external out, it usually needs for patient with T pipe life 1-2 months, life was inconvenient, as what laparoscopic common bile duct exploration was performed the operation popularizes, by
Cause abdominal cavity adhesion light compared with abdominal in laparoscopic surgery, generally requires patient with T and manage longer time or even 3 months, be
Pain of the patient with T pipe is reduced, has the report of the postoperative direct suture choledochus of exploration of common bile duct, but the technology is for jaundice
It is heavier, it is postoperative to need to keep biliary drainage unobstructed, subtract yellow patient as early as possible and be not suitable for, and directly after suture due to pressure of biliary tract compared with
Height, suture seepage of bile is relatively conventional, influences patient's post-operative recovery.
Summary of the invention
The purpose of the present invention is to provide Endobiliary drainage bracket is implanted into through choledochoscope, to solve to mention in above-mentioned background technique
The current main two schemes for the treatment of choledocholithiasis out, one kind are to remove out choledocholithiasis by retrograde cholangiopancreatography art,
Defect is to destroy this sphincter difficult to understand, and can not take out intrahepatic calculi and cholecystolithiasis；Another kind is that exploration of common bile duct takes stone,
T Tube Drain, defect are T pipe by outside stomach wall lead body, it usually needs patient was with T pipe life 1-2 months, and life is inconvenient, with abdomen
Popularizing for hysteroscope exploration of common bile duct operation, since laparoscopic surgery causes abdominal cavity adhesion light compared with abdominal, generally requires patient
There is the postoperative direct suture gallbladder of exploration of common bile duct in band T the pipe longer time or even 3 months in order to reduce pain of the patient with T pipe
The report of general pipeline, but the technology is heavier for jaundice, it is postoperative to need to keep biliary drainage unobstructed, it is uncomfortable to subtract yellow patient as early as possible
It closes, and since pressure of biliary tract is higher directly after suture, suture seepage of bile is relatively conventional, influences asking for patient's post-operative recovery
Topic.
To achieve the above object, the invention provides the following technical scheme: being implanted into Endobiliary drainage bracket through choledochoscope, including
Drainage stent, the end surface of the drainage stent are fixed with anti-dropout arm, and the side of the anti-dropout arm is relative to drainage branch
Frame is internally provided with scale marker.
Preferably, another end surfaces of the drainage stent offer the first side opening, the side setting of first side opening
There is the second side opening.
Preferably, the opposite of first side opening offers the 4th side opening, and the opposite of the second side opening offers
Three side openings.
Preferably, the drainage stent is hollow round estrade structure, and drainage stent is flexible material component.
Preferably, the anti-dropout arm is mounted on the surface of scale marker by the angle of tilting, and anti-dropout arm is
Cylindrical structure.
Compared with prior art, the beneficial effects of the present invention are: the Endobiliary drainage bracket designed in the present invention is total in gallbladder
It is routinely placed after pipe exploratory operation, choledochus opening can be directly sutured when placing and completing, managed, change outer without long-term band T
Drainage is the interior drainage in the case of physiology, avoids bile loss, hence it is evident that improve patients ' life quality, while guaranteeing biliary drainage,
Conducive to postoperative jaundice decline, liver function protecting greatly reduces bile leakage probability after directly suture bile duct, and in later period wound
When healing, the anti-dropout arm of design is convenient in biliary tract being placed in duodenum through choledochoscope, and having prevents biliary tract rack inverse
To falling off into biliary tract, lead to not take out through duodenoscope, so as to directly extract bracket by gastroscope, without being hospitalized, subtract
Reply cost is lacked.
