PATIENT-SPECIFIC BONE GRAFTING SYSTEM AND METHOD

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 aspatial geometry therebetween, the model being specific to a patient. A patient-specific instrument g...

Beschreibung
Zusammenfassung:	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 aspatial 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 donorbone 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. 种用于为采集移植物而生成用于患者特异性切割引导器械的模型的系统，其包括由植入物界面表面、骨界面表面以及其间的空间几何形状所限定的移植物的模型，该模型特异于患者。患者特异性器械生成器
