Sinus protection sheath with pressure control of choledochoscopy

Abstract

The invention relates to a sinus protection sheath with pressure control of choledochoscopy. The device comprises a sinus protection sheath body, the sinus protection sheath body is a hollow structure, the two sides of the inner wall of the sinus protection sheath body are respectively provided with a first opening and closing flap and a second opening and closing flap, the bottoms of the first opening and closing flap and the second opening and closing flap extend to the outside of the sinus protection sheath body through the bottom opening of the sinus protection sheath body, and the first opening and closing flap and the second opening and closing flap are respectively connected to the inner side of the sinus protection sheath body through an elastic force arm and an adjusting ferrule.An adjusting rod movable up and down is arranged in the adjusting ferrule and passes through the adjusting ferrule, one end of the adjusting rod extends to the outside of the top of the sinus protection sheath body, and the other end of the adjusting rod is connected to a rotating force arm. One end of the rotating force arm is movably connected with the adjusting rod, and the other end is rigidlyconnected to one end of the elastic force arm adjacent to the first opening and closing flap and the second opening and closing flap. According to the present invention, physical damage to human sinus can not be caused by the device, and the scope of exploration can be expanded.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a choledochoscope pressure-controlling sinus tract protective sheath. Background technique [0002] Biliary tract exploration, T-tube biliary external drainage is a common biliary surgery method. The T-tube is pulled out 6-8 weeks after the operation, and the sinus connecting the skin and the biliary tract will be formed around the T-tube. In recent years, with the popularity of percutaneous transhepatic biliary puncture and external drainage, the number of cases of sinus choledochoscopy has increased rapidly after surgery. At present, the standard operation procedure of postoperative choledochoscope is as follows: 1) After pulling out the T-tube, insert the choledochoscope repeatedly into the human sinus into the biliary tract for operation; Give plenty of saline. [0003] Such an operation process has the following three disadvantages: [0004] 1) Physical damage to human ...

Problems solved by technology

[0006] 3) Obvious loss of choledochoscope

Directly inserting the choledochoscope into the sinus of the human body will not only cause harm to the human body, but also cause significant wear and tear on the choledochoscope, with a high damage rate and significantly shorten the service life of the choledochoscope
