The present invention consists of an illumination apparatus capable of beingattached to surgical instruments, and providing a better illumination of theoperating field during surgical procedures. The illumination apparatus comprisesa light source (1), such as a LED, connected to a power supply source (2). The lightsource (1) and part or all of the power supply source are housed in a purpose builtcasing (3). Said casing (3) has at least one attaching means (5) on its outer surfacewhich is suitable for removably attaching the illumination apparatus to a surgicalinstrument, being removed and re-attached to another. In a preferred embodimentof the invention, said at least one attaching means (5) is a magnet. These attachingmeans allow for an easy attachment and removal of the illumination apparatusto several different surgical instruments during a particular surgical procedure.They also allow for the position of the illumination apparatus to be easily shiftedalong the surgical instrument. Due to its weight, design and size, the illuminationapparatus of the present invention does not interfere with the normal use of thesurgical instruments. Said present invention is aimed exclusively at open-airsurgeries and in particular those in which it is necessary to obtain a good illuminationof normally poorly illuminated organ cavities.
