Abstract

The invention relates to a surgical instrument comprising a handle portion or mounting portion and a functional portion and/or tip, wherein a display device is provided on the instrument and includes or enables displays which serve to assist in image-guided and/or navigation-assisted surgery. It also relates to a method for navigating a surgical instrument, wherein its position is determined and tracked by means of a medical tracking system and the position data is processed within the framework of medical navigation by means of a medical navigation system, wherein displays for navigation assistance and/or for assisting in image-guided surgery are provided on the instrument or on an element which is positionally assigned to the instrument or fastened to the instrument.

Claims

1. A surgical instrument comprising:

a handle portion or mounting portion;

a functional portion; and

a display device configured to display information to assist in at least one of image-guided or navigation-assisted surgery,

wherein at least one of the handle portion, the mounting portion or the functional portion is formed as sterile disposable items.

2. The instrument according to claim 1, wherein the sterilely packaged disposable items are made of a plastic material.

6. The instrument according to claim 1, further comprising an integrated sensor system configured to provide tracking information, said tracking information processed by a medical navigation system.

7. The instrument according to claim 6, wherein the integrated sensor system is an inertial sensor system.

8. The instrument according to claim 1, further comprising a data processor assigned to the display device, wherein the data processor is configured to track and identify the surgical instrument.

9. The instrument according to claim 1, wherein the integrated data processor in the instrument is configured to evaluate an inertial sensor system in connection with external and additional or redundant tracking information in order to improve 3D localization.

10. The instrument according to claim 1, wherein the display device is provided integrally with the instrument or removably attached to the instrument via an adaptor, wherein a spatial assignment of the instrument and the adaptor with respect to each other is known and reproducible.

11. The instrument according to claim 10, wherein the display device is attached to the instrument via the adaptor.

12. The instrument according to claim 1, wherein the display comprises or displays tracking markings that are trackable by a tracking system.

13. The instrument according to claim 1, wherein the display device includes a navigation image display.

14. The instrument according to claim 1, wherein the data processor is provided integrally with the instrument or is removably attachable to the instrument.

15. The instrument according to claim 14, wherein the data processor is attached to the instrument via an adaptor.

16. The instrument according to claim 1, wherein the data processor and the display device form an integrated navigation system.

17. The instrument according to claim 16, wherein the integrated navigation system is a portable navigation system.

18. The instrument according to claim 16, wherein the integrated navigation system is removably attached to the handle portion or mounting portion via an adaptor.

19. The instrument according to claim 1, wherein the functional portion comprises at least one of

a functional instrument tip including a fastening device configured to fixedly attach the instrument to an object, or

a calibration receptacle configured to receive an object to be aligned to the instrument.

20. The instrument according to claim 1, wherein at least one of the display device or the data processor is provided as a removably attachable element and comprises a sterile covering.

21. The instrument according to claim 20, wherein the sterile covering is a sterile drape or a shell which is sterile.

3. The instrument according to claim 3, wherein components of the instrument which are attached to the handle portion, mounting portion or the functional portion are formed as sterile disposable items.

4. The instrument according to claim 3, wherein the sterile disposable items are sterilely packaged disposable items.

5. The instrument according to claim 4, wherein the sterilely packaged disposable items are made of a plastic material.
