Multi-clamp apparatus for external bone fixator

A multi-clamp apparatus for an orthopedic exterior fixator, the multi-clamp apparatus comprising:

• first and second clamp arms, each clamp arm having an elongated longitudinal body extending between first and second ends, each clamp arm having a plurality of crescentic channels, the crescentic channels of the first clamp arm opposing the crescentic channels of the second clamp arm;
• first and second outrigger bars, each outrigger bar having an elongated body extending between an attached end and a distal end, the attached ends being attached to the first and second clamp arms, respectively;
• and
• first and second size changeable knobs, each knob designed to change between a first size and a second size, the first size having at least a part that extends a greater distance in a direction outwardly from a threaded body of the respective screw as compared to the second size so that a greater rotational torque can be applied relative to the respective screw in connection with the first size as compared to the second size, each knob having a central screw turn actuator engaged with the respective threaded screw that permits relative movement of the first and second clamp arms when rotational force is applied to at least one of the knobs, each screw extending along a respective screw axis;
• and
• wherein each size changeable knob includes at least one collapsible turn lever, each turn lever having a longitudinal body extending between a movable end and a hinged end, each central screw turn actuator having an outer side and an inner side, the hinged ends of each turn lever being connected via respective hinges to the outer sides of the respective central screw turn actuators, the movable ends of each turn lever being movable between a collapsed position where the movable ends are situated over the outer side of the respective central screw turn actuator and an un-collapsed position where the movable ends are situated outwardly from the outer sides of the respective central screw turn actuator.

A multi-clamp apparatus for an orthopedic exterior fixator, the multi-clamp apparatus comprising:

• first and second clamp arms, each clamp arm having an elongated longitudinal body extending between first and second ends, each clamp arm having a plurality of elongated crescentic channels, the crescentic channels of the first clamp arm opposing the crescentic channels of the second clamp arm, each opposing pair of the crescentic channels, when brought together, being of an adequate length, size, and shape to engage and secure a bone pin;
• first and second outrigger bars, the first and second outrigger bars having first and second elongated bodies, respectively, extending between first and second attached ends, respectively, and first and second distal ends, respectively, the first and second attached ends being attached to the first and second clamp arms, respectively;
• and
• first and second torque amplifying knobs, each knob having a plurality of collapsible turn levers, each turn lever having a longitudinal body extending between a movable end and a hinged end, each knob having a central screw turn actuator with an outer side and an inner side, the hinged end of each turn lever being connected via a hinge to the outer side of the respective central screw turn actuator, the movable end of each turn lever being movable between a collapsed position where each lever is situated over the outer side of the respective central screw turn actuator and an un-collapsed position where the movable end is situated outwardly from the outer side of the respective central screw turn actuator, each central screw turn actuator being engaged with a respective means for causing relative movement of the first and second clamp arms when rotational force is applied to the respective knob.
