Sternum replacement plate made in one piece

Abstract

Provided is an implant for sternum replacement including an upper face, a posterior face, extensions for fitting with the ribs and extensions for fitting with the manubrium, wherein that implant is manufactured in a single piece with high performance engineering polymers, with an anatomical adjustment tailored to each patient, which guarantees the reduction of the number of elements in contact with the patient, facilitating and speeding up the surgical procedure, at the same time, the required mechanical and flexibility properties, are guaranteed.

Claims

1. A sternum implant comprising: a main body section; a top end of the main body section configured to be located at a manubrium when fixed to a body of a patient; a bottom end of the main body section, distal to the top end, wherein the main body section extends from the top end to the bottom end; an upper face; a posterior face; first extensions for fitting with ribs; and second extensions for fitting with the manubrium, the second extensions forming a shape of the top end; wherein the sternum implant is manufactured with engineered polymers; wherein the upper face, the posterior face, the first extensions, and the second extensions are structurally integral with the main body section as a function of the sternum implant being manufactured as a single piece; wherein the bottom end is free of extensions; wherein the sternum implant is configured to be fixed to a rib bone of a body of a patient with screws.

2. The sternum implant of claim 1, wherein the sternum implant is a sternum replacement implant.

3. The sternum implant according to claim 1, wherein: a geometry of the posterior face fits anatomically with a mediastinum, a geometry of the first extensions are anatomically adjusted with the ribs, and a geometry of the second extensions are anatomically adjusted with the manubrium.

4. The sternum implant according to claim 1, wherein the engineered polymers include PEEK, PEKK, or Carbon Fiber reinforced PEEK where fibers are continuous or discontinuous.

5. The sternum implant according to claim 1, wherein the sternum implant is custom developed for a patient with CAD/CAM techniques and computer-assisted surgical planning.

6. The sternum implant according to claim 1, wherein the sternum implant is manufactured by machining or additive manufacturing.

Description

BRIEF DESCRIPTION

(1) Some of the embodiments will be described in detail, with references to the following Figures, wherein like designations denote like members, wherein:

(2) FIG. 1 corresponds to a front view of the implant for sternum replacement; and

(3) FIG. 2 corresponds to a posterior view of the implant for sternum replacement.

DETAILED DESCRIPTION

(4) Embodiments of the present invention is directed to an implant for sternum replacement, which is composed of the following components:

(5) Sternum implant (1) comprising an upper face (11), a posterior face (12), extensions for coupling with the ribs (2), extensions for coupling with the manubrium (3), wherein that implant is made from high performance engineering polymers, such as PEEK, PEKK or carbon fiber reinforced PEEK, where those fibers are continuous or discontinuous, in order to guarantee the necessary mechanical properties, at the same time as they are biocompatible, lightweight and highly resistant and flexible which facilitates the reduction of the number of pieces necessary for the intervention, also reducing the risk of infection.

(6) This implant is manufactured in a single piece by machining, in accordance with CAD/CAM techniques and computer-assisted surgical planning, in order to adjust to the anatomy of each patient, specifically, the geometry of that posterior face fits anatomically with the mediastinum, the geometry of those fitting extensions with the ribs is anatomically adjusted with the ribs, the geometry of those fitting extensions with the manubrium is anatomically adjusted with the manubrium.

(7) This implant is fixed to the patient's body, by direct fixation or through holes where titanium or steel screws are placed, or with titanium and steel plates.

(8) Although the present invention has been disclosed in the form of preferred embodiments and variations thereon, it will be understood that numerous additional modifications and variations could be made thereto without departing from the scope of the invention.

(9) For the sake of clarity, it is to be understood that the use of “a” or “an” throughout this application does not exclude a plurality, and “comprising” does not exclude other steps or elements.
