Abstract

There is described a system and a method for assisting a user manipulating an object during a surgery, the method comprising: tracking the object in a sterile field in which surgery is being performed at a location using a tracking device which generates tracking data; processing the tracking data using a processing device located outside the sterile field to generate position and orientation information related to the object; and sending the position and orientation information related to the object to a displaying device positioned in the sterile field adjacent to the location at which the surgery is being performed, for display to the user.

First claim

The invention claimed is:

1. A system for assisting an object manipulation in a sterile field during a surgery, the system comprising:
a tracking device for tracking at least the object relative to a bone while the at least one object and the bone are in a sterile field in which surgery is being performed, and for generating tracking data for the object;
at least one processing device positioned inside or outside of the sterile field, for generating tracking information related to the object by processing the tracking data received from the tracking device;
a sterilized displaying device located in a volume within the sterile field defined as being above a plane of an operating table, the volume being delimited by a periphery of the operating table, the displaying device for displaying the tracking information received from the processing device to the operator during the surgery, the displaying device having a touch-screen located in the volume for interaction with the operator; and
a support connected to the displaying device and positioning the displaying device over the operating table and into said volume of the sterile field.

2. The system as in claim 1 , wherein the displaying device is positioned within a same field of view as a location at which the surgery is being performed from a surgeon's viewpoint, for display of the information to the surgeon during manipulation of the object.

3. The system as in claim 1 , further comprising an imaging device for acquiring images of at least one of the object and a location at which the surgery is being performed, the displaying device displaying the images.

4. The system as in claim 3 , wherein the processing device comprises a coordinate translating device for translating the object position and orientation information into a coordinate system relative to the images.

5. The system as in claim 1 , wherein the displaying device is integral to a portable handheld computing device in said volume during the surgery.

6. The system as in claim 5 , wherein the at least one processing device is integral to the portable handheld computing device.

7. The system as in claim 1 , wherein the displaying device includes multiple displaying devices each including a dedicated user interface, with at least one said displaying device in the sterile field.

8. The system as in claim 7 , wherein each of the displaying devices are dedicated to a specific role.

9. The system as in claim 7 , further including a communications interface for assigning a communication priority between one of the displaying devices and the processing device, the communication priority being in accordance with the dedicated user interface involved in the communication.

10. The system as in claim 1 , further including a database for the at least one processing device, the database storing information on at least one of the surgery, the object and the location, the information for being displayed by the displaying device.

11. The system as in claim 1 , wherein the tracking device comprises markers placed on the object, the markers for being tracked using one of: a mechanical frame, an electro-mechanical device, an acoustic device, an electro-magnetic device, an optical device and a radio-frequency device.

12. The system as in claim 1 , wherein the at least one processing device and the sterilized displaying device have transmitters for wireless communication therebetween.

13. The system as in claim 1 , wherein the support is integral to the operating table.

14. The system as in claim 1 , wherein the at least one processing device has a transmitter for wireless communication with at least one server of the system for additional computing to be performed by the at least one server.
