FIELD: medicine. ^ SUBSTANCE: invention concerns medical equipment, namely to devices for gamma radial therapy and can be used for treatment of malignant tumours. The equipment contains a leg with fastening for placing on a tomograph table, the carriage bound to bars with possibility of vertical moving and fixing, the console connected to the carriage, the co-ordinate device and a guide of a therapeutic radioactive implant. Thus the carriage is bound to the bars referring in the form of a ruler and has possibility of additional moving across, and the protractor is fixed on each flexure of a rotary part. The guide is executed in the form of a plate with placed in apertures referring for installation of a therapeutic radioactive implant, containing the extended carrier in a kind of concentrically located tubes bridged by the extremities among themselves and supplied with sources of radioactive radiation, located along longitudinal axis of the extended carrier. The sources are executed in the form of the silver substrates having the form of rings, covered with radioactive iodine-125 and placed on an external surface of the internal tube, thus the surface of the internal tube between the silver substrates and surfaces of the internal tube between silver substrates and the extremities of tubes bridged among themselves are covered by a varnish, and the distance between silver substrates makes 0.6-1.2 of substrates width. ^ EFFECT: reduction of terms of gamma radial therapy at the expense of an exact implant locating, provided with the equipment. ^ 4 cl, 3 dwg |
