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.
Claims20
An fixator comprising:
- at least one rail;
- at least one pin suitable for use in bone fixation;
- and
- at least one clamp system having a pin clamp, a rail clamp functionally connected by a hinge, wherein the pin clamp is capable of holding the pin in a first plane and the rail clamp is capable of holding the rail in a second plane;
- and the pin clamp is hingedly adjustable to the rail clamp.
2 more elements
A clamp system for a fixator comprising:
- a first clamp area comprises a pin clamp top and a pin clamp bottom attached to a pin clamp bolt, wherein the pin clamp top and pin clamp bottom that together define a pin passage and the pin clamp top and bottom can be flexed to allow for a pin to be snapped into the pin passage;
- a hinge that is attached to the pin clamp bolt and hingedly connects the first clamp area to a second clamp area;
- wherein the hinge comprises a bolt assembly capable of fixing the first clamp area in a fixed position in relation to the second clamp area;
- wherein the second clamp area comprises a rail clamp top and a rail clamp bottom that are attached to a rail clamp bolt, wherein the rail clamp top and rail clamp bottom together define a rail passage, and the rail clamp top and bottom can be flexed to allow for a rail to be snapped into the rail passage.
1 more element
An external fixation device comprising:
- a rail;
- at least one pin;
- a first clamp and a second clamp, each clamp comprising a first spring-loaded component configured to attach the clamp to the rail, a second spring loaded component configured to attach to at least two pins, and a hinged component that can adjustably connect the first spring loaded component to the second spring loaded component, wherein both clamps are attachable to the same rail.
