POSITIONING APPARATUS FOR BIOMEDICAL USE
A medical positioning apparatus including a telescopic member extending between first and second ends and having an adjustable length; a support member for receiving an object; a base member securable to a base; a first joint mechanism movably securing the support member to the first end of the telescopic member; a second joint mechanism including a housing with a top portion directly rotationally connected to the second end of the telescopic member, and at least one side portion directly rotationally connected to the base member and movably securing the base member to the second end of the telescopic member, a locking device operatively connected to the first and second joint mechanisms and the telescopic member, the locking device operable between a locked position and a released position; and a lock activation device to unlock the locking device biased in the locked position.
1 . A medical positioning apparatus for positioning and holding an object, comprising:
a telescopic member extending between a first end and a second end and having an adjustable length;
a support member for receiving the object;
a base member securable to a base;
a first joint mechanism movably securing the support member to the first end of the telescopic member;
a second joint mechanism including a housing with a top portion directly rotationally connected to the second end of the telescopic member, a bottom portion opposite the top portion, and at least one side portion directly rotationally connected to the base member and movably securing the base member to the second end of the telescopic member, the first and second joint mechanisms each having at least two rotational degrees of freedom;
a locking device operatively connected to the first and second joint mechanisms and the telescopic member, the locking device operable between a locked position in which the support member, the base member, and the telescopic member are lockingly interconnected together and the length of the telescopic member is fixed, and a released position in which the support and base members are free to pivotally move with respect to the telescopic member and the length of the telescopic member is adjustable, the locking device being passively biased in the locked position; and
a lock activation device to unlock the locking device biased in the locked position in order to adjust the length of the telescopic member and a relative position of the support member, the base member, and the telescopic member.
