Abstract
A system and method for measuring a surgical rod are disclosed. The system includes a processor, a probe in communication with the processor and configured to trace along a surface of the implant, a tracking system in communication with the processor and the probe for generating first data representing at least one of linear and rotational movement of the probe during a first trace along the surface of the implant, wherein the processor is configured to receive the first data and generate a first graphical representation of the implant based on the first data, and a display in communication with said processor for displaying the graphical representation of the implant based on the first data. Various methods are also disclosed.
Claims19
A system for measuring an implant, comprising:
- a processor;
- a probe in communication with the processor and configured to trace along a surface of the implant;
- a tracking system in communication with the processor and the probe for generating first data representing at least one of linear and rotational movement of the probe during a first trace along the surface of the implant;
- wherein the processor is configured to receive the first data and generate a first graphical representation of the implant based on the first data;
- and
- a display in communication with said processor for displaying the first graphical representation of the implant based on the first data,
- wherein the processor is configured to calculate an angular offset between at least two portions of the implant based on the first data and display the angular offset.
A method for measuring an implant, comprising:
- moving a probe along a surface of the implant prior to positioning the implant within a patient, the implant being positioned within an implant cavity of the probe as the probe moves along the surface of the implant, the implant cavity comprising a tracking element configured to communicate positional and rotational data about the implant;
- tracking by a tracking system movement of the probe to obtain first data representing the implant;
- storing the first data in a memory;
- displaying on a display a first image representing the implant based on the first data;
- calculating by a processor based on the first data angular offsets between at least two points of the implant;
- and
- displaying the angular offsets.
A method for measuring a surgical rod, comprising:
- inserting at least one bone fixation element into a patient;
- bending the rod prior to positioning the rod within the patient;
- capturing first data using a probe to represent a shape of the rod after the bending step;
- storing the first data in a memory;
- displaying a first image representing the rod based on the first data;
- positioning the rod in the patient;
- connecting the rod to the at least one bone fixation element;
- capturing second data using the probe to represent the shape of the rod after the positioning step;
- storing the second data in the memory;
- and
- displaying a second image representing the rod based on the second data.
