Abstract
The application provides methods for providing a surgical guide for placement on an anatomical part wherein the guide is provided with one or more dedicated push features that can be used as pressure points for applying force onto the surgical guide. The application further provides guides comprising one or more push features which can be used as a pressure point for applying force onto said guide.
Claims15
A method for providing a patient-specific device for placement on a patient's anatomical part, the method comprising the steps of:
- determining one or more areas on the anatomical part that can be used for the design of one or more contact surfaces on a patient-specific device configured to be placed on the anatomical part;
- determining, based on the one or more contact surfaces, an axis of least-constrained rotational direction of the patient-specific device on the anatomical part, an axis of least-constrained translational direction of the patient-specific device on the anatomical part, or both;
- and
- designing the patient-specific device with one or more contact surfaces and one or more push features that can be used for applying force onto the patient-specific device;
- wherein the one or more push features are designed such that a force applied thereto is perpendicular to the axis of least-constrained rotational direction of movement of the patient-specific device on the anatomical part, parallel to the axis of least-constrained translational direction of movement of the patient-specific device on the anatomical part, or both.
