Benefits of technology

[0005] The fixator can be used in multi-planar and multi-joint correction, is percutaneous and, therefore, minimally invasive, and can provide additional stability and mobility when compared to fixation devices currently in use. Additional advantages of the present invention over existing devices include the design and adjustability to easily assemble and disassemble components of the system without disturbing pins already set into the patient's bone or the rest of the system itself.

Problems solved by technology

Specifically, it is often times desirable to have an external fixation device that is capable of accommodating a wide variety of pin placements.

Embodiment Construction

[0014] While the present invention is susceptible of embodiments of various forms, there is shown in the drawings, and will hereinafter be described some exemplary and non-limiting embodiments, with the understanding that the present disclosure is to be considered an exemplification of the invention. It is not intended to limit the invention to the specific embodiments listed.

[0015] As can be seen in FIGS. 1-7, in one embodiment of the present invention, a fixator 10 comprises a rail 12, at least one clamp system 14, and a pin 16. Generally, the clamp system 14 is configured to attach to both the rail 12 and the pin 16, which is connected to the bone 40 for fixation and stabilization. The fixator 10 may further include compression and distraction nuts 18 functionally connected to the fixator 10 to allow for additional manipulation of bone healing and growth. The clamp systems 14 can be splined to receive and hold rails 12 and pins 16.

[0016] The rails12 may be any size or shape, an...

Abstract

A fixator for use in the reconstruction of acute, chronic and traumatic injuries to the upper and lower extremities. The fixator has a unique clamping system that allows for the snapping in of pins and rails, and for multi-planar fixation of bones.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to external fixation devices, and more particularly to an external fixation device for use in the reconstruction of acute, chronic and traumatic injuries to the upper and lower extremities. BACKGROUND OF THE INVENTION [0002] In the medical field, patients can suffer from acute, chronic, and / or traumatic injuries to the upper and lower extremities. In such circumstances, it is often desirable to stabilize and reconstruct the bones of the afflicted area. To that end, systems have been developed to help stabilize and reconstruct injured bones. One type of system employed in the past is an external fixation system. [0003] All bone injuries are not the same. As a result, the best mode of treatment for a bone injury can vary significantly depending on the size of the person, size of the injured bone, and type of bone injury. Specifically, it is often times desirable to have an external fixation device that is capable of...
