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:
establishing, in a processor, a predetermined proximity relation between at least a first surgical device adapted to perform a first function associated with the surgical procedure, and a second surgical device adapted to perform a second function associated with the surgical procedure, wherein the predetermined proximity relation is associated with a selected step of the surgical procedure associated with the second function;
tracking at least the first surgical device;
detecting the predetermined proximity relation between the first surgical device and the second surgical device adapted to perform the second function associated with the surgical procedure, as the first surgical device is brought in said predetermined proximity relation while the first surgical device is tracked;
as an automatic response to the predetermined proximity relation being detected, automatically triggering an activation of the selected step of the surgical procedure associated with the second function; and
displaying information related to the selected step.

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 a mating engagement between the first surgical device and the second surgical device.

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 selected 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 automatically triggering the action of 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 the second surgical device with the second surgical device being a tibial digitizer, and wherein displaying information related to the selected step comprises displaying a tibial axis.

10. The method according to claim 1 , wherein tracking the first surgical device is part of a given step of the surgical procedure.

11. The method according to claim 10 , wherein automatically triggering the activation of the selected step includes changing from the given step to the selected step in the surgical procedure of a computer-assisted surgery application.

12. The method according to claim 10 , wherein tracking the first surgical device includes displaying information relating to the given step associated with the first function.

13. The method according to claim 12 , wherein automatically triggering the activation of the selected step includes causing a change in the displaying of information.

14. The method according to claim 1 , wherein detecting a predetermined proximity relation includes receiving a signal from a proximity switch associated with at least one of the first surgical device and the second surgical device.
