Title: Obstetric forceps with adjustable distance stop in handle - comprises slider moving in slot so its projection slides in groove in other half handle (SW 14.6.76)
Inventor: SIPLI WOLFGANG DR MED
IPC: A61B17/44
Filed: 1975-10-16
Abstract: Theforceps are made in two separate parts, which do not cross, but which latch together at a hinge pin either at the end of the handle (22a, b) or between the handle and the blades. In each case, the handle of one half of the forceps holds a slider (15), which can be moved by hand along a slot (14), and which carries a projection (15a) extending into a groove (16a) in the other half handle.
