Abstract: A model production device generates one or more contact bodies of a patient-specific surgical instrument model based on a parameterized model of a patient's bone. The parameterized model includes a predetermined number of polygons each having a predetermined position relative to the patient's anatomy. The parameterized model may be generated based on a three-dimensional model that was generated based on multiple images of the patient's bone. The model production device adds parametric fixed geometry to the patient-specific surgical instrument model based on the parameterized model and subtracts the three-dimensional model of the patient's bone from the patient-specific surgical instrument model. Each contacting body may be positioned at a high-confidence part of the parametric model, and the parametric fixed geometry may be positioned at a low-confidence part. A patient-specific surgical instrument may be manufactured based on the patient-specific surgical instrument model.
