Description
Technical Field
The invention relates to the field of medical equipment, in particular to a choledochoscope pressure-controlled sinus tract protecting sheath.
Background
The biliary tract exploration, T-shaped tube biliary tract external drainage is a common biliary tract operation mode, the T-shaped tube is pulled out 6-8 weeks after the operation, sinus tracts which are formed around the T-shaped tube and are used for connecting skin and biliary tract are created for the biliary tract exploration through the sinus biliary tract choledochoscope after the operation, and in recent years, along with the popularization of the percutaneous transhepatic biliary tract puncture external drainage technology, the number of various operation cases of the sinus biliary tract choledochoscope after the operation is rapidly increased. The operation standard flow of the choledochoscope after the operation at the present stage is as follows: 1) After the T-shaped tube is pulled out, the choledochoscope is directly and repeatedly inserted into the sinus tract of the human body to enter the biliary tract for operation; 2) In order to keep the operation field clear, a large amount of physiological saline is continuously input into the biliary tract in the operation process.
Such an operational flow has three drawbacks:
1) Physical damage to the sinus tract of a human body by a choledochoscope. The choledochoscope is inserted and contacted with the human body Dou Daoshi, the wall of the choledochoscope insertion part is directly and repeatedly rubbed with the human body wound tissues of the sinus tract, so that obvious pain and discomfort of a patient are necessarily caused, and the external force effect is caused during the repeated insertion of the choledochoscope into the sinus tract, so that the human body sinus tissues are possibly caused to bleed out and even rupture, the hemorrhagic shock and the acute diffuse peritonitis are caused, and the life safety of the patient is even endangered due to the need of emergency operation treatment.
2) The pressure in the biliary tract increases rapidly. Under normal physiological conditions, the pressure in the biliary tract of a human body is not more than 1.96kPa, when the pressure exceeds 2.45kPa, biliary reflux occurs, biliary tract contents can break through blood vessels in the liver sinus and enter peripheral circulation, a great amount of bacteria and endotoxin substances exist in the bile in the diseased biliary tract, the substances enter the peripheral circulation to cause cholangitis and even infectious shock to endanger life, and a great amount of physiological saline is rapidly introduced into a limited biliary tract space in the biliary tract operation process, if the physiological saline cannot be timely discharged, the biliary tract pressure can be rapidly exceeded a critical value to cause cholangitis, and a patient immediately presents severe chills and even blood pressure drops, so that the operation is forced to stop for rescue.
3) The choledochoscope loss is obvious. Choledochoscope is one of precision medical equipment, and most of the equipment in domestic medical institutions comes from the import of japan and germany. The choledochoscope is directly inserted into the sinus tract of a human body, so that the choledochoscope is not only damaged to the human body, but also is obviously worn, the damage rate is high, and the service life of the choledochoscope is obviously shortened.
