Description
Technical Field
The invention relates to the technical field of separating pliers, in particular to a pair of pliers heads of a membrane separating pliers and the membrane separating pliers.
Background
With the widespread use of laennec-based membranes in anatomic hepatectomy, it has become relatively easy to segment more than two secondary branches of the liver (Glisson) as a whole extrahepatic. For example, the S4 and S3 segments can be separated and blocked from entering the outer sheath of the hepatic blood flow common trunk. Because the Laennec membrane is thin and easy to break, no special Laennec membrane separating forceps exist at present, and the bending radian of the forceps head can not be adjusted randomly by a common separating forceps, so that the membrane is easy to break and the blood is easy to bleed in the separating process, and the separation can be continued only by blocking the blood flow of the liver. The blocking of the liver blood flow can cause liver ischemia, so the blocking time must be controlled within fifteen minutes, and then the blocking needs to be released, and the whole separation process is quite complicated and time-consuming.
