Abstract

The implant has a thorax clip, and an area provided adjacent to ribs and including recesses which correspond to a progression and a contour of the ribs as shape. The recesses exhibit rounded-off edges, where dimensions of the recesses exhibit sufficient large clearance for soft parts. Ridges are attached alternatively to the recesses at the area without rib contacts.

Description

Die Erfindung betrifft ein Implantat für die Trichterbrustkorrektur mit Vertiefungen, die dem Verlauf und der Kontur der anliegenden Rippen als Abdruck entspricht.The The invention relates to an implant for the funnel chest correction with depressions that match the shape and contour of the adjacent Ribs as impression corresponds.

Die Trichterbrust (Pectus excavatum) ist eine Fehlbildung der Thoraxwand. Die operative Korrektur erfolgt überwiegend minimalinvasiv durch temporäre Implantation eines Thoraxbügels, dem sogenannten „Pectus bar”. Der C-förmige Bügel wird mittels Schablonen vor der Implantation angepasst.The Funnel chest (pectus excavatum) is a malformation of the chest wall. The surgical correction is mostly minimally invasive by temporary implantation of a thorax bar, the so-called "Pectus bar". The C-shaped Temple is adjusted by means of templates before implantation.

Die WO/2005/055844 beschreibt einen Thoraxbügel mit seitlich angebrachter einstückiger Stabilisatorplatte.The WO / 2005/055844 describes a thorax bar with side-mounted one-piece stabilizer plate.

Nachteil dieses Thoraxbügels ist die ebene Oberfläche. Dadurch kommt es wegen der zu geringen Kontakt- und Auflagefläche an den Rippen oft zur Dislozierung, Abgleiten oder Abkippen des Bügels am beweglichen Thorax. Eine Korrekturoperation mit Einsetzen eines weiteren Thoraxbügels ist oft unumgänglich. Es kann zu Einschränkungen der Atemtätigkeit sowie zu starken Schmerzen kommen.disadvantage This thorax strap is the plane surface. This is because of the lack of contact and support surface often on the ribs for dislocation, slipping or tilting of the Stirrups on the movable thorax. A correction operation with insertion another thoracic hanger is often unavoidable. It may cause respiratory limitations as well come to severe pain.

Aufgabe der vorliegenden Erfindung besteht daher darin, ein gegenständliches Implantat zu schaffen, das ohne zusätzliche Gewebeschädigung und Verkomplizierung der Operationstechnik die genannten Nachteile vermeidet oder reduziert.task Therefore, the present invention is an objective To create an implant without additional tissue damage and Complication of the surgical technique avoids the disadvantages mentioned or reduced.

Gelöst wird die erfindungsgemäße Aufgabe dadurch, dass Vertiefungen an den Stellen des Thoraxbügels eingearbeitet werden, die den Rippen anliegen. Diese Vertiefungen des Thoraxbügels entsprechen dem schrägen Verlauf und der Kontur der Rippen als Abdruck. Entsprechend den anatomischen Gegebenheiten ist der Thoraxbügel individuell zu vermessen und anzupassen.Solved The object of the invention is characterized in that Recesses incorporated in the areas of the thorax bar become attached to the ribs. These depressions of the thoracic bracket correspond to the oblique course and the contour of the ribs as an impression. According to the anatomical conditions is the Individually to measure and adapt chest strap.

Durch die jetzt hohe Kontaktfläche werden Schmerzen erheblich reduziert und das Implantat besser örtlich fixiert.By The now high contact area will hurt considerably reduced and fixed the implant better locally.
