Systems and methods for shielding medical personnel from radiation are provided. A radiation-shielding barrier is positioned between the medical personnel and the radiation source. The radiation-shielding barrier includes an opening such that a portion of the table extends through the opening in the barrier. Medical personnel are protected from secondary radiation transmitted through the patient via a special layering technique of a first, flexible sterile drape, a flexible radiation-resistive drape, and a second flexible sterile drape. The system includes an upper shield and a lower shield of independent movement and a linking mechanism between the two, while maintaining the radiation seal. The system also includes a mechanism for maintaining the radiation barrier between the upper shield and the patient aperture hoop, preventing a radiation gap from forming between the flexible portions of the system (e.g. flexible drapes, curtains, etc.) and the non-flexible portions of the system (e.g. upper shield, lower shield, radiopaque transparent window, etc.).

Method and apparatus for shielding medical personnel from radiation

A radiation protection shield for protecting medical personnel from radiation being applied to a patient positioned on a table. The shield includes a frame and a primary screen including a radiation-resistant material connected to said frame.

Lower shield for radiation protection system

A radiation protection system for protecting medical personnel from radiation being applied from a radiation source to a patient positioned on a table. The system includes a shield for positioning above the table having an inner frame sized and shaped for receiving the patient when the patient is positioned on the table, and a plurality of rods extending outward from the inner frame. The shield also has an outer frame surrounding the inner frame and connected to the plurality of rods, and a radiopaque flexible panel attached to the rods.

Radiation protection system

A prosthetic device adapted to be secured to a supporting bone by a thickness of acrylic bone cement. The prosthetic device has an outer surface which includes a plurality of spacers projecting therefrom. The spacers are made of an acrylic material, such as polymethyl methacrylate (PMMA), and are adapted so that when the prosthetic device is positioned against the supporting bone, the spacers provide a uniform space between the bone and prosthetic device, thus uniformly controlling the thickness of cement. The acrylic spacers will repolymerize and bond with the layer of acrylic bone cement. The nature of the bond formed between the new acrylic bone cement and the acrylic spacers should eliminate the stress concentrations at the interface between the spacers and the cement layer, thereby enhancing fixation of the prosthesis.
