Abstract

The invention relates to a device which is used intra-operatively to localise carcinogenic tumours and ganglia precisely and in a three-dimensional manner and to correlate the surgical instruments with the images in real time. The structural elements of the functional navigator include: a surgical navigator, a camera which is used to obtain functional images, the position-finding elements of the camera and the surgical instruments and the specific software program which combines all of the information from the aforementioned elements. The surgical navigator is essentially characterised in that the position of the cameras which acquire the functional images is controlled by the navigator by means of emitters or reflectors which are disposed in said cameras. The information relating to the camera images and the position of same, which is determined by the navigator, is analysed by a specific software program and combined with the position of the surgeon'"'"'s surgical instruments in order to obtain images.

Claims

1. A surgical navigator which uses information starting from three-dimensional functional images obtained in real time, essentially characterised in that the position of the cameras which acquire the functional images is in turn controlled by the navigator by means of emitters or reflectors located in them;

the information from the images of the cameras and from the position of them determined by the navigator being analysed by a specific software program and combined with the position of the surgeon'"'"'s surgical instruments in order to obtain images.

2. A surgical navigator which uses information starting from three-dimensional functional images obtained in real time, according to claim 1, wherein its structural elements comprise:

a surgical navigator, a camera which is used to obtain functional images, the position-finding elements of the camera and the surgical instruments and the specific software program which combines all of the information from the aforementioned elements.

3. A surgical navigator which uses information starting from three-dimensional functional images obtained in real time, according to claim 1, wherein the functional images are obtained from a gamma camera, a PET camera or any camera adapted for obtaining said type of image.

4. A method for positive and precise detection of carcinogenic tumours in the operating theatre and its combination with the surgical instruments, which comprising obtaining three-dimensional functional images of said tumours and determining the location of said tumours by means of the surgical navigator of claim 1.

5. A method for positive and precise detection of carcinogenic ganglia in the operating theatre and its combination with the surgical instruments, which comprising obtaining three-dimensional functional images of said ganglia and determining the location of said ganglia by means of the surgical navigator of claim 1.
