A surgical robotic intra-operative radiation therapy device having at least one cylindrical rotating shutter defining, in conjunction with a capsule, a defined conical beam of radiation oriented through the end of said capsule comprising:
- a robotic device configured for surgical use having at least one robotic arm configured to be manipulated remotely;
- for a patient having a surgical incision, an interchangeable capsule for irradiating at least one patient tissue by a desired width of radiation beam exposure, said capsule for irradiating said at least one tissue and said incision being sized for said capsule to be insertable through said surgical incision;
- said capsule having a longitudinal central capsule axis and having an emission aperture opening at the end of said capsule which opens to an emission cavity internal to said capsule, said capsule having at least one cylindrical rotating shutter rotating perpendicular to said central capsule axis for alternately occluding and uncovering said aperture opening to said emission cavity;
- each said at least one cylindrical rotating shutter having an electromechanical means of rotating each of said at least one cylindrical rotating shutters;
- said capsule having shielding selected to attenuate radiation exterior to said capsule;
- said capsule having a remotely operable means for controlling at least one of said at least one cylindrical rotating shutters;
- a first of said at least one cylindrical rotating shutters having a circular conical aperture conforming to a desired width of radiation beam exposure with an apex of said circular conical aperture being centered on a radiation source centered in said cylindrical rotating shutter, said circular conical aperture of said at least one cylindrical rotating shutter conforming to a defined cone, said defined cone being calculated by the selected distance of said desired width of radiation beam exposure beam from the radiation source through the capsule to the patient tissue;
- each at least one succeeding cylindrical shutter from said first of said at least one cylindrical rotating shutters set outwardly from and perpendicular to said capsule center axis having a conical aperture conforming to said defined cone, and the series of said at least one cylindrical rotating shutters in combination with said emission aperture opening conforming to said defined cone in a manner that based on each conical aperture of all of said at least one cylindrical rotating shutters being aligned a smooth cone of radiation without penumbra internal to the capsule is formed from the radiation source to the exterior edge of the capsule and configured for projecting the desired width of radiation beam exposure on the patient tissue;
- said remotely operable means for controlling each said shutter cooperating with at least one electromechanical means of rotating each of said at least one cylindrical rotating shutters to align all of said at least one cylindrical rotating shutters with said emission aperture opening;
- said robotic arm having a first means for robotic arm electrical communication and control;
- said device having a shuttle capsule holder mountable on said robotic arm, said shuttle capsule holder having a second means for electrical communication and control compatible for purposes of interchangeability with said capsule;
- said capsule being mountable on said shuttle capsule holder;
- said shuttle capsule holder having a third means for electrical communication and control compatible for purposes of interchangeability with said first means for robotic arm electrical communication and control;
- a means for positive attachment between said robotic arm and said shuttle capsule holder, said means for positive attachment being compatible for purposes of interchangeability with said shuttle capsule holder and said first and second means for electrical communication and control;
- said capsule having means for closing said at least one cylindrical rotating shutters to a fail-safe closed position shielding the patient tissue from a direct line through at least one of said cylindrical rotating shutters to the radiation source based on whether power is lost to said capsule;
- a general purpose computer for transmitting data to and from said capsule;
- and
- said intraoperative therapy device having at least one robot arm configured to be operated remotely cooperating with said capsule to move said aperture of said capsule adjacent to patient tissue to be irradiated, in a manner that by operating said at least one electromechanical means of rotating, all of said at least one cylindrical rotating shutters are aligned to expose said patient tissue to said radiation source disposed within said capsule.
