Title
(EN) PATIENT-SPECIFIC BONE GRAFTING SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE GREFFE OSSEUSE SPÉCIFIQUE AU PATIENT
Abstract
(EN)
A system for generating a model of a patient specific cut guide instrument for harvesting a graft comprises a model of a graft defined by an implant interface surface, a bone interface surface, and a spatial geometry therebetween, the model being specific to a patient. A patient-specific instrument generator outputs the model of the patient specific cut guide instrument, the patient-specific instrument generator including a position determination module for orienting and positioning at least a first guide axis, and for positioning an abutment on a model of a donor bone as a function of the spatial geometry, and an instrument body generator module for generating a model of the patient specific cut guide instrument comprising a body supporting a cut guide to perform a depth cut in the donor bone positioned and oriented as a function of a contact of the body with the abutment on the donor bone, and of the model of the graft.

La présente invention concerne un système pour générer un modèle d'un instrument de guide de coupe spécifique au patient pour recueillir une greffe qui comprend un modèle de greffe défini par une surface d'interface d'implant, une surface d'interface osseuse, et une géométrie spatiale entre celles-ci, le modèle étant spécifique à un patient. Un générateur d'instrument spécifique au patient délivre en sortie le modèle de l'instrument de guide de coupe spécifique au patient, le générateur d'instrument spécifique au patient comprenant un module de détermination de position pour orienter et positionner au moins un premier axe de guide, et pour positionner une butée sur un modèle d'un os donneur en fonction de la géométrie spatiale, et un module de générateur de corps d'instrument pour générer un modèle de l'instrument de guide de coupe spécifique au patient comprenant un corps supportant un guide de coupe pour réaliser une coupe de profondeur dans l'os donneur positionné et orienté en fonction d'un contact du corps avec la butée sur l'os donneur, et du modèle de la greffe.
