Abstract
A choledochoscope intraoperative airbag belongs to the surgical operation or diagnosis-used auxiliary instrument manufacturing technical field. The gas bag comprises essentially a catheter (3), valves (4) which are arranged on the two ends of the catheter (3), a bag body (1) with an inner hole (2), etc. The length of the bag body (1) is 40-60mm. The diameter of the bag body (1) is 8-12mm when the bag body (1) is not aired. The whole structure and the size range can satisfy the clinical requirements of a surgical operation and solve the shriveling (Vt, Vi) problem on the lower segments of an extrahepatic bile duct and an intrahepatic bile duct of a liver and a choledochus and the filling problem during the operation. The pressure in the lower segments of the intrahepatic bile duct and the choledochus can be strengthened to enlarge the inner diameter and solve the extrahepatic bile duct and the intrahepatic bile duct of the liver shriveling without tension problem. The airbag is beneficial to the inspection during the operation, the biopsy and the stone removal and has the advantages of simple structure and less complicating diseases. The airbag also can be used to substitute a converting cap during the laparoscopy and choledochoscope inspections and the stone removal. The damages of the cholangioscope are reduced.
Description
Technical field
The present invention relates to air bag in a kind of choledochoscope art, belong to surgical operation or diagnosis manufacturing technology field with assistive device.
Background technology
Clinically during the multiple calculus of surgical operation therapy extrahepatic duct, usually can run into thinner stones in intrahepatic bile duct or ductus choledochus hypomere calculous obstruction at present, sunken because of extrahepatic duct in the art, it is all very thorny to get stone with biliary tract stone extraction pincers or choledochoscope, is difficult to take out.Often take 2 months reuse choledochoscopes of postoperative in one's hands and in T type pipe sinus tract, get stone, bring life inconvenience and painful to patient.
Summary of the invention
The object of the present invention is to provide a kind of reasonable in designly, purposes is wide, air bag in simple, convenient, the safe choledochoscope art.
The present invention is an air bag in the choledochoscope art, it is characterized in that comprising conduit, places the valve at conduit two ends and the utricule of band endoporus.
The length of described utricule can be 40～60mm.The described utricule not diameter during qi of chong channel ascending adversely can be 8～12mm.
The present invention is reasonable in design, overall structure and size range can satisfy operating clinical requirement, can solve extrahepatic duct in the art and the ductus choledochus hypomere is sunken, do not have full problem, especially can increase the pressure in stones in intrahepatic bile duct and the ductus choledochus hypomere pipe and enlarge internal diameter, solve sunken, the tension-free problem of extrahepatic duct.Check in the favourable Rhizoma Atractylodis Macrocephalae, get biopsy and get stone, material softness of the present invention, not damaged, simple to operation, complication is few, also can be used for choledochoscope inspection under the peritoneoscope, substitutes the effect of conversion medicated cap when getting stone, reduces the damage of choledochoscope.
Description of drawings
Accompanying drawing is an overall structure sketch map of the present invention.
The specific embodiment
The present invention places utricule 1 formation such as grade of the valve 4 and the band endoporus 2 at conduit 3 two ends mainly by conduit 3.The length of utricule 1 is 40～60mm, and the utricule 1 not diameter during qi of chong channel ascending adversely is 8～12mm.
Inside and outside liver during the multiple calculus row of biliary tract abdominal, after the incision ductus choledochus takes out the calculus of getting easily, in the choledochoscope inspection or when getting stone, the choledochoscope head is coated lubricant, choledochoscope is inserted in the endoporus 2 then, insert in the bile duct gently together with utricule 1, in utricule 1, inject a certain amount of gas or water according to bile duct internal diameter size by conduit 3, be generally 5～10ml, make the bile duct intracavity have certain force of strain to get final product, avoid the too high and rupture of bile duct of tension force.After the basket on the choledochoscope entangles calculus, the gas in the utricule 1 or water taken out flatly pull out externally together, it is the same to insert behind the bile duct in utricule 1 gas injection or water method once more.The perforator of 10mm is extracted in biliary tract inspection or when getting stone under the peritoneoscope, and utricule 1 inserts 2/3 from perforator is most advanced and sophisticated, annotates a certain amount of gas or water after inserting choledochoscope again, then perforator is inserted perforator from the former puncturing hole of stomach wall and can operate.
Claims (3)
1. air bag in the choledochoscope art is characterized in that comprising conduit (3), places the valve (4) at conduit (3) two ends and the utricule (1) of band endoporus (2).
2. by air bag in the described choledochoscope art of claim 1, the length that it is characterized in that described utricule (1) is 40～60mm.
3. by air bag in the described choledochoscope art of claim 1, it is characterized in that described utricule (1) not the diameter during qi of chong channel ascending adversely be 8～12mm.
