Abstract:
1. A device for positioning a surgical head clamp comprising a base and a plurality of arms, said plurality of arms each having a longitudinal axis and opposite ends, with a first arm being connected to the base, an intermediate second arm being connected between an end of said first arm and an end of a third arm with said arms connected so as to be pivotable about an end of the adjacent arm, at least one arm including a locking lever to lock the associated arm against pivoting relative to the adjacent arm, said third arm having a free end and including a spherical member carried in a socket and comprising an integrally formed mounting tube extending radially outwardly of said spherical member, said mounting tube being positionable at a selected point relative to the axis of said arm, said third arm including a gripping device to restrain movement of said spherical member in said socket, said device including a mounting post of a head clamp insertable into said mounting tube and having a plurality of recesses spaced about the surface of said post adjacent one end thereof, said mounting tube including a releasable locking device for engaging and holding said mounting post against rotation and withdrawal from said mounting tube so that accidental release of the mounting post is prevented, said third arm including a locking member for locking said spherical member against movement and for locking said third arm against pivoting movement relative to said second arm wherein said locking member is a lever pivotally carried adjacent the free end of said third arm and having an extension member extending through an opening in the end of said third arm to engage a toggle member which controls the locking of said spherical member in said socket.
