Abstract

A computer-assisted surgery system comprises a first surgical device with a tracking unit tracked during a surgical procedure and adapted to perform a first function associated to the surgical procedure. A second surgical device is adapted to perform a second function associated to the surgical procedure. A triggered unit is triggered when the first surgical device and the second surgical device reach a predetermined proximity relation. A surgical procedure processing unit tracks the first surgical device. A trigger detector detects a triggering of the triggered unit. A CAS application operates steps of a surgical procedure. A controller commands the CAS application to activate a selected step associated with the second function in the surgical procedure when the trigger detector signals a detection. An interface displays information about the selected step in the surgical procedure.

First claim

The invention claimed is:

1. A method for progressing through steps of a surgical procedure of a computer-assisted surgery application, comprising:
tracking at least a first surgical device adapted to perform a first function associated with the surgical procedure, in one step of the surgical procedure;
displaying information on an interface related to the one step of the surgical procedure during said tracking;
detecting a predetermined proximity relation of the first surgical device, the predetermined proximity relation related to one other step of the surgical procedure different than said one step;
automatically activating the one other step of the surgical procedure when the predetermined proximity relation is detected; and
automatically displaying information related to the one other step on the interface as a response to said automatically activating.

2. The method according to claim 1 , further wherein tracking the first surgical device comprises receiving tracking data from a micro-electromechanical system.

3. The method according to claim 1 , wherein detecting the predetermined proximity relation comprises detecting an engagement between the first surgical device and a second surgical device adapted to perform a second function associated with the surgical procedure.

4. The method according to claim 3 , further comprising tracking the second surgical device.

5. The method according to claim 4 , wherein tracking the second surgical device comprises tracking the second surgical device from the tracking of the first surgical device and from a known geometry of the mating engagement between the surgical devices.

6. The method according to claim 4 , wherein displaying information related to the one other step comprises displaying information related to the tracking of the second surgical device.

7. The method according to claim 1 , further comprising confirming that the detected predetermined proximity relation respects predetermined conditions prior to activating the selected step.

8. The method according to claim 1 , wherein tracking the first surgical device comprises tracking a tibial reference on a tibia of a patient.

9. The method according to claim 8 , further comprising tracking a second surgical device with the second surgical device being a tibial digitizer, and wherein displaying information related to the one other step comprises displaying a tibial axis.
