Patent ID: 6860848

Claim:
A urological resectoscope for children, comprising: a main casing ( 6 ); a distally extending stem tube ( 9 , 9 ′) that is adapted to be coupled to said main casing ( 6 ); an optic guide plate ( 4 ), said optic guide plate being mounted at a fixed distance from said main casing; a slider ( 10 ), said slider being displaceably guided between said main casing and said optic guide plate; an optic tube ( 1 ), said optic tube extending longitudinally through said resectoscope; a drive rod ( 14 , 14 ′), said drive rod being releasably secured to said slider at a first radial distance and a first angular position from said optic tube, extending from the slider parallel to the optic tube into the main casing, and then extending at a second radial distance and a second angular position and parallel to the optic tube through the stem tube, said first radial distance being greater than said second radial distance, wherein said stem tube tightly encloses the drive rod and the optic tube, and wherein a distal end of said drive rod projects from a distal end of said stem tube and supports a surgical implement; wherein a free space ( 7 ) is provided in the main casing ( 6 ), said free space having a length corresponding at least to a desired range of motion of the drive rod ( 14 , 14 ′), the drive rod comprising a deviation site ( 22 , 16 , 22 ′, 22 ″) disposed within the free space wherein said rod is angled relative to the optic tube ( 1 ) so as to change from the first radial spacing at the first angular position to the second radial spacing at the second angular position.
