Embodiments of the invention include an external fixation system that includes at least one external fixation strut that is both acutely adjustable and precisely adjustable and related methods of adjustment. Acute adjustment may be accomplished using one or more mobile jaws that may be engaged with or disengage from a threaded rod of each external fixation strut. Precise adjustment of each external fixation strut may be accomplished after releasing a lock biased toward a locked position. When each external fixation struts lock is released, a portion of each of the precise adjustment mechanism of each external fixation strut may be activated to increase and decrease the length of each of the at least one external fixation struts.

Disclosed herein are external fixation frames for correcting bone deformities. The external fixation frames include a top fixation ring and a bottom fixation ring coupled to one another by at least two struts. A half ring is coupled to bottom fixation ring. The bottom fixation ring is u-shaped. One or more rocker members may be coupled to the bottom fixation ring. The half ring may be hingedly coupled to the bottom fixation ring such that it can rotate with respect to the bottom fixation ring from a first position to a second position.

A lower limb traction device for intramedullary nail implantation operation includes a chassis with a first end portion and a second end portion opposite to each other; a first slide block slidably provided at a second end portion of the chassis in a longitudinal direction of the chassis; a lower leg support plate having two opposite end portions and two opposite side portions, wherein one end portion is connected to the first slide block; an upper leg back plate having opposite end portions and opposite side portions, wherein one end portion of the upper leg back plate is connected to the second end portion of the chassis, and the other end portion of the upper leg back plate is connected to the other end of the lower leg support plate; and a pulling mechanism provided at the first end portion of the chassis.

A clamp for an external fixator, preferably of the quick attachment type comprises at least one first attachment provided with at least one bar housing seat for a bar of the external fixator and/or with at least one screw housing seat for a bone screw; at least one second attachment provided with at least one bar housing seat; a connector which, in a tightened configuration, passes through said first attachment and said second attachment locking the bars and/or bone screws within the bar housing seats and/or the screw housing seats; and which, in an open configuration, frees the entrance to at least the bar housing seat of said second attachment; and auxiliary connection means between said first attachment and said second attachment which are active in said open configuration.

An external fixation system for the correction of long bone deformities includes an elongate beam element having an engagement feature along a longitudinal edge of the elongate beam element, a connector element secured to the elongate beam and structurally configured to support a first bone anchor extending from the external fixation system, and a movable carriage engaged with the engagement feature along the longitudinal edge of the elongate beam element and selectively movable along the engagement feature of the elongate beam element. The movable carriage is selectively lockable into a position along the elongate beam element. The movable carriage is structurally configured to support a second bone anchor extending from the external fixation system.

The present invention relates to a medical positioning device, comprising a first carriage assembly configured for mounting a first pin, wherein the orientation of the first pin is adjustable by means of a first spherical joint with three rotational degrees of freedom with an angular range of at least ±10° each, a second carriage assembly configured for mounting a second pin, wherein the orientation of the second pin is adjustable by means of a second spherical joint with three rotational degrees of freedom with an angular range of at least ±10° each and an extension assembly configured for adjusting a distance between the first pin and the second pin.

Embodiments of the invention include an external fixation system that includes at least one external fixation strut that is both acutely adjustable and precisely adjustable and related methods of adjustment. Acute adjustment may be accomplished using one or more mobile jaws that may be engaged with or disengage from a threaded rod of each external fixation stmt. Precise adjustment of each external fixation strut may be accomplished after releasing a lock biased toward a locked position. When each external fixation struts lock is released, a portion of each of the precise adjustment mechanism of each external fixation strut may be activated to increase and decrease the length of each of the at least one external fixation struts.

A bone fracture fixation system including reference pins inserted into bone fragments of a patient in a first configuration and an image capture device configured to capture an image of the reference pins, and the bone fragments. The system includes a processor configured to receive and pre-process the captured image data. The processor pre-processes the image data by virtually re-positioning the reference pins in the first configuration into a second configuration, wherein the re-positioning virtually re-positions the bone fragments into normal alignment; and virtually generating a support device. The system includes a point-of-care production apparatus that produces a three-dimensional model of the virtually generated support device in a form that can be applied to the patient. The three-dimensional support device generated by the point-of-care production apparatus is configured to receive the reference pins in the first configuration; and simultaneously re-positions and fixes the bone fragments into normal alignment.
