System for Automatic and Personalized Modelling/Bending of Surgical Prosthesis for Correction of Pectus Excavatum Based on Pre-Surgical Imagyology Information

Abstract

The present invention relates to a system of modelling/bending of surgical prothesis used in the correction of pectus excavatum, allowing its pre-operative personalization according to the thoracic morphology of each patient. The system allows, on the basis of the information of the thoracic CT-scan, the application of a personalized prosthesis, reducing the initial discomfort provoked by the prosthesis and subsequent period of adaptation to the same, allowing still to reduce the duration of the surgery, and offering the patient a virtual perspective of the foreseen postoperative result.

For the effect, the system is constituted by: - Simulation and modelling of surgical prosthesis, supported in software modules, developed specifically for the effect, being executed in a personal computer; - Command and control of the machine, supported in software modules that are executed in a controller; - An equipment that includes electronic and mechanical components, for the bending of personalized surgical prosthesis, to apply in the patient.

The software modules that are executed in the personal computer have a friendly interface with the user, mainly a set of menus that guide it step by step to reach the intended goal - modelling the surgical prosthesis and simulation of the cosmetic result of its application in the patient. After the process of modelling and simulation, this application generates a set of points of control that will be sent to the controller. This includes software modules that allow receiving the control points sent by the application from the personal computer and based on this information commands and controls the equipment in an adaptive manner in the process of bending of surgical prosthesis.
