Description
Technical Field
The utility model relates to the technical field of separating forceps, in particular to a membrane separating forceps head and a membrane separating forceps.
Background
With the widespread use of laennec-based membranes in anatomical hepatectomy, branches above the second level of the liver (Glisson) as a whole can be relatively easily separated extrahepatic. For example, the S4 and S3 segments can be separated and blocked extrasheath for hepatic blood flow co-drying. Because the Laennec membrane is thin and easy to break, no special Laennec membrane separating forceps exist at present, but the common separating forceps cannot adjust the bending radian of the forceps head at will, so that the membrane is broken easily and bleeding occurs in the separating process, and liver blood flow is blocked to continue separation. The blocking of liver blood flow causes liver ischemia, so that the blocking time must be controlled within fifteen minutes, and then the blocking needs to be released, and the whole separation process is quite tedious and time-consuming.

In some embodiments, the first binding clip portion has a maximum width in a perpendicular direction along the second end of the first arcuate portion of from 0.5 cm to 0.8cm. Thus, the forceps head forceps part with the maximum width of 0.5-0.8 cm is relatively matched with the laennec membrane gap.
In some embodiments, the left side and/or the right side of the end of the first binding clip handle fixedly connected to the first binding clip jaw is concave inward to form an arc, and/or the left side and/or the right side of the end of the second binding clip handle fixedly connected to the second binding clip jaw is concave inward to form an arc.
