The present invention provides an Image guided whole body stereotactic needle placement device with falling arc (3), comprising a circular base plate (1 ), a circular supporting ring (2) that is placed in the groove (8) in base plate (1 ) for supporting ring 2), a carrying arc (3) for needle guide (6) which has a foot (23) on either side, a fixing screw (4) which fixes the carrying arc (3) for the needle guide (6) with the supporting ring (2) and the base plate (1 ), a locking pin (29) which fixes the carrying arc (3) for needle guide (6) with the supporting ring (2) making the carrying arc (3) for the needle guide (6) perpendicular to the base plate (1 ) and a needle guide (6) that slides on the superior surface of the carrying arc (3) for the needle. This device is both CT and MR compatible, and can be used for precisely positioning a needle tip at a particular point inside the body. The needle can be used for taking tissue samples / delivering drugs/ delivering energy to ablate tissues / aspirating cystic lesions. The patient has to hold breath while the needle is being passed into regions that move on respiration. This device has a falling arc that allows quick release of the needle after placement, so as to quickly allow free breathing for the patient. This feature allows utilisation of this device in chest and abdomen also. The device can be placed on the skin or on the exposed organ during surgery. The device is light weight, small and can be used in patients of any age.La présente invention concerne un dispositif de placement daiguille stéréotactique de corps entier guidé par des images avec un arc tombant.
