  • Speculum with arresting device
    Patent number: 4899734
    Abstract: An arresting member (5) is rotatably mounted about the lengthwise axis of a lever handle (2) of a pair of pliers. The arresting member (5) is directed towards the other lever handle (1) and penetrates with its free end (11) through a slot (12) in this other lever handle (1). The shank (13) of the arresting member (5) is flattened so that the arresting member in one rotational position can axially freely slide in the slot (12). The largest radial extent of the shank (13) slightly exceeds the width of the slot (12) so that the arresting member (5) is clamped in another rotational position in the slot (12). By fabricating the arresting member (5) from a deformable material, the pair of pliers can be operated also with the arresting pin in this rotational position. Upon sliding through the slot (12) the arresting member (5) is thereby deformed.
