Abstract
A computer assisted surgery system and a method for operating a computer assisted surgery system is described therein. The system and method includes providing a virtual representation of a medical device to provide an easier application of a medical device, such as an implant or the like. The described system and method allows for simple and fast positioning of a medical device to be applied, such as an implant, for example.
Claims16
Method for operating a computer assisted surgery system, the method comprising:
- positioning of a reference body in relation to an anatomical structure;
- taking a first 2-dimensional image of the reference body and the anatomical structure at a first angle, the reference body virtually representing a position of a medical device to be applied to the anatomical structure;
- viewing the image data obtained from the first 2-dimensional image on a display device;
- viewing the anatomical structure with a virtual representation of a medical device to be applied superimposed on the image data;
- viewing an optimal virtual position of the medical device to be applied with respect to the anatomical structure so as to obtain a best fit with respect to rules for allowable ranges for applying the medical device to the anatomical structure;
- and
- modifying the position of the reference body.
A computer-readable medium having instructions stored thereon for operating a computer assisted surgery system, the instructions, when executed by a processor, cause the processor to perform a method comprising:
- detecting a position of a reference body based on image data obtained from a first 2-dimensional image taken at a first angle;
- determining the position of the reference body in relation to an anatomical structure, the reference body virtually representing a position of a medical device to be applied to the anatomical structure;
- superimposing the anatomical structure with a virtual representation of a medical device to be applied, based on the detected position of the reference body in relation to the anatomical structure;
- providing rules for allowable ranges for applying the medical device in relation to the anatomical structure;
- determining an optimal position of the medical device to be applied with respect to the anatomical structure so as to obtain a best fit with respect to the rules for allowable ranges;
- and
- displaying the optimal position virtually.
A computer assisted surgery system comprising:
- a reference body in relation to an anatomical structure, the reference body virtually representing a position of a medical device to be applied to the anatomical structure;
- a detector device being adapted for detecting a position of the reference body in relation to the anatomical structure;
- a database including virtual medical device information;
- and
- a computation device being adapted for superimposing the anatomical structure with a virtual representation of a medical device to be applied based on an output of the detector device, and modifying the position of the reference body and optimizing the virtual position of the medical device to be applied with respect to the anatomical structure so as to obtain a best fit with respect to predetermined rules for allowable ranges for applying the medical device in relation to the anatomical structure.
