HAND PROBE FOR LOCAL RADIOMETRY Russian patent published in 2005 - IPC

FIELD: medical equipment, in particular, instruments of radiocontrolled surgery, applicable for detection of malignant tumors.

SUBSTANCE: the hand probe for local radiometry has a detector of gamma radiation, having a photodetector, optically conjugate to a scintillator and a collimator, fastened on a handle with an electric wire passing inside it, which connects the detector of gamma radiation to a connector installed in the base of the handle. It is also provided with a second detector of gamma radiation fastened on a dial, whose axle passes through the optical axis of the second gamma detector, the optical axes of the two detectors of gamma radiation are in the plane passing perpendicularly to the dial axle, and the dial zero readout is positioned on a straight line parallel with the optical axis of the first detector. Besides, the hand probe has a dial turning mechanism and an angle-of-turn indicator.

EFFECT: enhanced aiming of delivery of the surgical instrument.
