DESCRIZIONE DESCRIPTION

A corredo di una domanda di brevetto per invenzione industriale avente per titolo: In support of a patent application for industrial invention entitled:

“Placca di fissaggio per osteosintesi di costole”. “Fixation plate for osteosynthesis of ribs”.

La presente invenzione propone una placca di fissaggio per osteosintesi di costole rotte per facilitare il consolidamento osseo in riparazione di una frattura o fessurazione di costole assicurando una stabilizzazione della costola al fine di ridurre il tempo di ricostruzione ossea e cicatrizzazione nel paziente. The present invention proposes a fixation plate for osteosynthesis of broken ribs to facilitate bone consolidation in repair of a fracture or fissure of ribs ensuring a stabilization of the rib in order to reduce the time for bone reconstruction and healing in the patient.

Le fratture e fessurazioni ossee delle costole richiedono una loro immobilizzazione e stabilizzazione per facilitare la osteosintesi ossea al fine di ripristinare l’integrità della struttura ossea. Fractures and bone cracks of the ribs require their immobilization and stabilization to facilitate bone osteosynthesis in order to restore the integrity of the bone structure.

Vi sono pochi sistemi in uso in chirurgia toracica per assicurare tale immobilizzazione e stabilizzazione delle costole. La soluzione 3D Rib Clip<TM >della STRASBOURG<TM>, con brevetto MX319918, consiste di una placca flessibile in titanio dotata fino a 9 ganci di fissaggio che vengono serrati durante l’applicazione chirurgica. Nel brevetto US 2002128654A1 si presenta una placca di fissaggio che si può fissare all’osso di una costola tramite una vite di fissaggio per lato. Il brevetto US 2008082101A1 propone una placca di acciaio inossidabile e titanio per osteosintesi di ossa tubolari, particolarmente costole, tramite una struttura a parti intercambiabili con elementi di ancoraggio ad uncino per il fissaggio stabilizzante delle parti ossee collegate. There are few systems in use in thoracic surgery to ensure such immobilization and stabilization of the ribs. The STRASBOURG <TM> 3D Rib Clip <TM> solution, with patent MX319918, consists of a flexible titanium plate equipped with up to 9 fixing hooks that are tightened during surgical application. In US patent 2002128654A1 there is a fixing plate that can be fixed to the bone of a rib by means of a fixing screw on each side. US patent 2008082101A1 proposes a stainless steel and titanium plate for osteosynthesis of tubular bones, particularly ribs, by means of a structure with interchangeable parts with hook anchoring elements for the stabilizing fixation of the connected bone parts.

Altre soluzioni di protezioni sono state sviluppate con stutture simili alle precedenti, con un funzionamento più complicato e meno robusto rispetto alla soluzione proposta in questo brevetto. I problemi principali delle soluzioni esistenti sono la mancanza di adattabilità alle varie geometrie delle costole di pazienti diversi, l’ingombro eccessivo e la difficoltà di assicurare una stabilizzazione senza movimento relativo tra i segmenti delle costole in trattamento. Other protection solutions have been developed with structures similar to the previous ones, with a more complicated and less robust operation than the solution proposed in this patent. The main problems of the existing solutions are the lack of adaptability to the various rib geometries of different patients, the excessive bulk and the difficulty of ensuring stabilization without relative movement between the segments of the ribs being treated.

La presente invenzione presenta una nuova placca di fissaggio di segmenti di costole per facilitare la osteosintesi di ricostruzione dell’integrità ossea assicurando assenza di movimento relativo o rotazione relativa delle parti di costola raccordate con la placca. La placca di fissaggio è caratterizzata da una struttura che consiste sia di fori per viti di fissaggio che di uncini deformabili per l’ancoraggio tridimensionale avvolgente al corpo osseo dei segmenti di costola da stabilizzare. The present invention presents a new plate for fixing rib segments to facilitate the osteosynthesis of bone integrity reconstruction by ensuring the absence of relative movement or relative rotation of the parts of the rib connected to the plate. The fixing plate is characterized by a structure consisting of both holes for fixing screws and deformable hooks for the three-dimensional anchoring of the rib segments to be stabilized to the bone body.
