Abstract:
1. Electromedical apparatus for intraoperative radiotherapy by means of an electron linear accelerator, including an arm (A) including means for generating electromagnetic waves, wherein said arm supports a radiating head ( 2 ), wherein said radiating head includes means for the linear acceleration of electrons ( 20 ), emitting an electron beam at an output ( 20 ′) of said means that generates electromagnetic waves through guiding means ( 6 ), characterized in that the guiding means includes in combination a first rotary coupling ( 4 ) and a second rotary coupling ( 5 ), respectively, wherein each rotary coupling includes a fixed portion ( 41 , 51 ) and a mobile portion ( 42 , 52 ), wherein the portions support said radiating head ( 2 ) upon said arm (A) respectively in pitch and in roll motion; said guiding means ( 6 ) including three mechanically separate tracts, of which an extreme tract ( 61 ) at the output of said means for generating electromagnetic waves and an extreme tract ( 62 ) of input ( 23 ) to said electron linear acceleration means ( 20 ), and an intermediate tract ( 63 ) therebetween to connect the extreme tracts and the three tracts ( 61 , 62 , 63 ) connect with the radiating head ( 2 ), wherein said extreme tracts ( 61 , 62 ) are respectively put into electric continuity through said first and second rotary couplings ( 4 , 5 ).
