DEVICE FOR ENDOSCOPIC SANITATION OF BILE DUCTS Russian patent published in 2014 - IPC A61M1/00 A61B17/94 A61M25/00 A61M39/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to endoscopic surgery, and may be used for endoscopic sanitation of bile ducts. A device for endoscopic sanitation of bile ducts comprises a catheter inserted into an endoscope for exudate (E) aspiration. The above catheter encloses a catheter for drug preparation (DP) delivery into a bile duct lumen. The catheters are connected to control handles. What is also provided is a cylinder used for DP delivery from a container into the bile duct lumen and coupled with a bracket arm regularly loaded for ensuring the DP pressure. There is also provided an aspiration cylinder coupled with a drive cylinder attached to a ruler with adjustable stops which impact a flatted valve lever and automatically switch the drug preparation delivery and aspiration. One flat connects pressurised water supply to the drive cylinder. The second one connects water drainage and releases the load on the DP cylinder and the ruler when the valve lever is in the other position. The drive cylinder, DP cylinder, E aspiration cylinder travel speeds are regulated by the valves. There are also provided valves for E delivery from the bile duct lumen and E delivery to the container.

EFFECT: invention provides automated endoscopic sanitation of the bile ducts by dispensing the drug preparations and exudate aspiration from the bile duct lumen; reduces the labour costs in treating patients with suppurative cholangitis by avoiding the medical personnel assistance of the sanitation procedure; controlled administration of the drug preparations enables avoiding a potential pressure increase in the biliary system followed by penetration of purulent bile elements into the circulatory bed (a biliovenous shunt) and as a consequence, developing common septic complications.
