Patent ID: 6893441

Claim:
A urological resectoscope ( 1 ) comprising an axial stem tube ( 2 ) having a distal end and a proximal end, said proximal end of said stem tube being affixed to a main block ( 3 ), a slide block ( 13 ) being supported proximally of said main block in an axially parallel displaceable manner relative to said main block ( 3 ), said slide block ( 3 ) being fitted with a seat ( 24 ), an affixing element ( 31 ) and an electrically contacting means ( 28 , 29 ), said resectoscope further comprising within it an hf-loaded electrode ( 18 ) which is associated with an electrode support ( 19 ) that is fitted with an electrically conducting wire ( 20 ) enclosed by an external insulator, said electrode ( 18 ) being supported so as to be axially displaceable beyond the distal end ( 7 ) of the stem tube ( 2 ), where the electrode support ( 19 ), when in an assembled resectoscope, running through the stem tube ( 2 ) and the main block ( 3 ) and into the seat ( 24 ), is affixed by the affixing element ( 31 ) and can be made to contact the electrically contacting means ( 28 , 29 ), wherein the affixing element ( 31 ) is configured proximally relative to the electrical contacting means ( 28 , 29 ) at the slider block ( 13 ) and wherein the electrically contacting means ( 28 , 29 ) is disposed within the slider block and relatively between the affixing element ( 31 ) and the main block ( 3 ).
