Abstract
By providing components securable to anchor pins or screws of different diameters as well as providing clamps which hold associated pins in any position during adjustments, an external fixation or adjustable frame structure is provided which is capable of being quickly and easily assembled in any desired configuration. In the present invention, the frame structure is retained in any assembled configuration in order to allow final adjustments to be made, prior to the final securement of the frame assembly in the precisely desired configuration by closure of each clamp member. In this way, an entire frame assembly is capable of being constructed, adjusted, and readjusted in order to assure each component is oriented in the precisely desired position prior to final closure of the clamping members. In one preferred embodiment, the clamping members employed in the frame structure of the present invention incorporate friction pins internally mounted in each clamp which engages the rod member once this rod is inserted into the jaws of the clamp. In this way, any rod member inserted into the clamping jaws contacts the surface of the jaws and the friction pin, preventing the rod member from…
